These networks support the family of 3GPP technologies including GSM and LTE for mission-critical applications. These operational networks are now looking to invest in the future of 3GPP by deploying 5G services. This includes the use of NR to support multiple low latency use cases (see 3GPP TR 38.825) resulting from various vertical industry domains, e.g., electrical power distribution grid & rail communication. These use cases often require less than the latency offered by LTE technology and thus need NR to fully support them.\n\u2022\tBand 26 and Band 8 in the USA (Band 106 is now allocated in RAN4 for Band 8 in the USA) using 3 MHz wide channels have set a precedent of existing networks requiring a growth path to NR to meet the needs of utilities, the critical infrastructure industry (CII), and enterprise customers \u2013 what 3GPP refers to as Smart Energy and Infrastructure (SEI).\n\u2022\tThe CII in the U.S. is currently planning to deploy private LTE systems in this spectrum allocation to leverage the transformative power of broadband in support of infrastructure modernization for energy, transportation, logistics and other industries.\n\u2022\tRail Communication in Europe is used for operational purposes to ensure the safety of millions of rail passengers. The Future Railway Mobile Communication System (FRMCS) forms the basis for digitizing rail operations to increase train path utilization and improve punctuality. Possibilities in 5G NR to operate in bandwidths <5 MHz (e.g., from around 3 MHz upwards) would enable parallel operation of FRMCS and GSM-R and massive infrastructure reuse. The responsible authorities and organizations in Europe have set the start of the migration from GSM-R to FRMCS for 2025.\n\u2022\tThe provision of simultaneous use of the 2x5.6MHz FDD in the 900MHz frequency band and the associated provision of bandwidths less than 5MHz for 5G NR thus has a key function to be able to start the migration from GSM-R to FRMCS in Europe.\n\u2022\tFor Public Protection and Disaster Relief (PPDR), 2 x 3MHz FDD in band 28 has been identified in Europe. \n\u2022\tThe lower 700 MHz spectrum in the USA was auctioned in 6 MHz blocks, based on the previous use for NTSC television channels. There is interest in deploying 3 MHz B12 LTE along with 3 MHz of NR in n85 in a 6 MHz block.\nNR specifications starting in Rel-15 defined a minimum bandwidth of 5 MHz channels. Although NR can support multiple channel bandwidths due to the flexible numerology implementation, channel bandwidths smaller than 5 MHz were not supported in NR. \nParent WIs have specified necessary changes to NR physical layer with minimum specification impact to operate in spectrum allocations from approximately 3 MHz up to below 5 MHz.

Furthermore, the intra-band carrier aggregation (CA) operation is also of interests to operators, which is not yet covered in Rel-17 work item scope. \nIn the Rel-17 WI, similar as FR2 handheld and other UE types, the single active panel operation was focused, i.e. only one active antenna panel at a time as baseline antenna assumption. Based on the Rel-17 conclusion, two panels shall be physically installed to flexibly support either forward or backward incoming signal direction; however, the restriction of only one active antenna panel limits utilizing two neighbouring RRHs to serve one HST UE in the bi-directional RRH deployment scenario. Accordingly, it is of importance to introduce the support of simultaneous reception with maximum 2 active panels at the train roof-mounted FR2 high power devices for the bi-directional RRH deployment scenario. \nAnother issue identified in Rel-17 work item is the large propagation delay difference from neighbouring RRHs to UE. For example in the uni-directional RRH deployment, it is identified that the signal propagation delay difference can be as much as 2.5us, which is much larger than CP length with 120kHz subcarrier spacing. In Rel-17 work item, the larger autonomous timing adjust step Tq is specified for FR2 HST UE, and the RAN4-based solutions for the uplink timing issue are focused, while other solutions, including involving other RAN working groups, are not fully studied. \nThe Rel-18 WI NR_HST_FR2_enh-Core has been 100% completed and NR_HST_FR2_enh-Perf has been 80% completed at RAN#102 meeting.

In Rel-15\/16\/17, MIMO features were investigated and specified for both FDD and TDD systems, of which major parts were for downlink MIMO operation. In Rel-18, it is important to identify and specify necessary enhancements for uplink MIMO, while necessary enhancements on downlink MIMO that facilitate the use of large antenna array, not only for FR1 but also for FR2, would still need to be introduced to fulfil the request for evolution of NR deployments. This comprises the following areas of enhancement. \nFirst, significant loss of performance for a UE at high\/medium speed has been observed in commercial deployments especially in multi-user MIMO (MU-MIMO) scenarios. As the performance loss is partly caused by outdated CSI, enhancements on CSI acquisition to alleviate such loss can be beneficial. Second, the unified TCI framework was introduced in Rel-17 which facilitates streamlined multi-beam operation targeting FR2. As Rel-17 focuses on single-TRP use cases, extension of unified TCI framework that focuses on multi-TRP use cases is beneficial. Third, due to the increasing need for multiplexing capacity of downlink and uplink demodulation reference signal (DMRS) from various use cases, there is a need for increasing the number of orthogonal ports for DMRS. Fourth, features for facilitating multi-TRP deployments have been introduced in Rel-16\/17 focusing on non-coherent joint transmission (NC-JT). As coherent joint transmission (CJT) improves coverage and average throughput in commercial deployments with high-performance backhaul and synchronization, enhancement on CSI acquisition for FDD and TDD, targeting FR1, can be beneficial in expanding the utility of multi-TRP deployments. Fifth, as advanced UEs (e.g. CPE, FWA, vehicle, industrial devices) become more relevant, introducing necessary enhancements to support for 8 antenna ports as well as 4 and more layers for UL transmission can offer the needed improvement for UL coverage and average throughput. Sixth, with the introduction of features for UL panel selection in Rel-17, advanced UEs (e.g. CPE, FWA, vehicle, industrial devices) can benefit from higher UL coverage and average throughput with simultaneous UL multi-panel transmission. Finally, some further enhancement to facilitate UL multi-TRP deployments via two timing advances (TAs) and enhanced UL power control can offer additional UL performance improvement.\n\nThe Rel-18 WI NR_MIMO_evo_DL_UL-Core has been 100% completed and NR_MIMO_evo_DL_UL-Perf has been 25% completed at RAN#102 meeting.

The objective of the corresponding Core Work Item approved at RAN#86 meeting was to introduce the support of non-terrestrial networks into the NR protocol and NG-RAN architecture, as well as the definition of requirements for devices and satellite access nodes, focussing on the two NTN bands \u2013 L-band and S-band \u2013 which were added as bands n255 and n256, respectively. At the same time there exist other satellite deployments which, as was presented during the RAN4#99 meeting, use mixed L-\/S-band pairing, Thus, during the RAN#98 meeting a new Rel-18 NTN spectrum WI was agreed with the objective of adding support for a new NTN band labelled as n254, where the UL is on the L-band and the DL is on the S-band. \nSince the Core and Performance parts of the RAN4 Work item on introduction of the L-\/S- band has achieved 100% completion as of RAN#102, it is necessary to introduce the conformance test requirements related to this band within the RAN5 test specifications. \n4\tObjective\n4.1\tObjective of SI or Core part WI or Testing part WI\nThe objective of this Testing Part Work Item is to:\n-\tIntroduce and specify a new release-independent NTN FDD band with a UE transmitting at 1610-1626.5MHz and SS transmitting at 2483.5-2500MHz within the conformance test specifications.\n-\tDefine channel bandwidths and SCS to be utilized in the conformance tests as defined in TS 38.101-5.\n-\tSupport UE Power class 3 (+23dBm). \n-\tIntroduce the test requirement updates for the following test cases\n\t-\tMaximum Output Power\n\t-\tMaximum Power Reduction\n\t-\tAdditional Maximum Power Reduction\n\t-\tAdditional Spurious Emissions\n\t-\tSpurious Co-existence \n-\tReference Sensitivity\n-\tBlocking Characteristics\n-\tAdditional spectrum emission \n-\tUpdate the band grouping in RRM test specifications with n254","secretary_remarks":"","agenda_item_sort_order":7,"ainumber":"4.1","ainame":"\tNew Work Item proposals - for intro only","tdoc_agenda_sort_order":14200,"status":"withdrawn","reservation_date":"2024-02-16 22:40:58","uploaded":"2024-02-17 08:36:42","revisionof":"","revisedto":"","release":"Rel-18","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_ran\/WG5_Test_ex-T1\/TSGR5__102_Athens\/Docs\/R5-241420.zip","group":"R5","meeting":"R5-102","year":2024,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
