The user may have both a personal and a business subscription in one device or has two personal subscriptions in one device for different services (e.g. use one individual subscription and one \u201cfamily circle\u201d plan). However, support for multi-USIM within a device is currently handled in an implementation-specific manner, resulting in a variety of implementations and UE behaviours. Standardizing support for such UE\u2019s can prove beneficial from a performance perspective in that network functionality can be based on predictable UE behaviour.\nCollision due to reception of paging when the UE is in IDLE\/INACTIVE mode in both the networks associated with respective SIMs was discussed in both SA\/CT and RAN, an IMSI offset was introduced to calculate an alternative IMSI for deriving the modified Paging Occasion to avoid paging collisions. Several features like gap pattern were designed for UE to notify Network A of its switch from Network A to network B, while paging indictor was introduced to indicate the UE whether the service is VoLTE\/VoNR. Standardization makes the states of UEs and networks to be more synchronously and bring better performance.\nThe Rel-17 SA1\/SA2 WI MUSIM had been almost finished all standardization work, and the related CT1 WI was already 65% completed at CT#93 (September 2021), for LTE_NR_MUSIM-Core in RAN2, the target date of completion is Q1 2022, in other words, the work of the core specifications will be completed soon.

LTE Band 39 (1880-1920 MHz) is a widely deployed TDD band in China. There are also 5G NR band n34 and band n39, which has been specified in Rel-15. Enabling co-existence of existing LTE deployment along with a NR addition in same band is essential to allow operators to refarm the existing LTE band 34 and n39, and improve the spectrum efficiency.\n3.1 DSS requirements for n34 and n39 NR band\nFor resource block level spectrum sharing, frequency alignment between LTE and NR is necessary to avoid inter-subcarrier interference. Following three features are needed for band 34 and 39 spectrum sharing.\n1.\t100 kHz channel raster support\nAs shown in the following table, 100 kHz channel raster is supported for n34 and n39 in Rel-15. \nReferred from TS38.101-1 Table 5.4.2.3-1: Applicable NR-ARFCN per operating band\n..\nThe NR band n34 and n39 already complies to this requirement. \n2.\t30 KHz SS block SCS support \nIn RAN4 #96-e meeting, RAN4 already agreed to add 30KHz SSB pattern case C in addition to 15KHz SSB for n34 and n39 from Rel-15 (R4-2011682). \nReferred from TS38.101-1 Table 5.4.3.3-1: Applicable SS raster entries per operating band\n..\nThe NR band n34 and n39 already complies to this requirement.\n3.\tUL 7.5kHz frequency shift for 15KHz data SCS\nIn section 5.4.2.1 of TS38.101-1 inclusion of band n34 and n39 for the list of bands supporting UL 7.5 kHz shift is required for 15 kHz SCS. DSS with 15 kHz SCS gives better spectral efficiency using RE level rate matching than RB level rate matching. \nGiven above justifications, spectrum sharing for b34\/n34 and b39\/n39 would be necessary and the following requirements should be supported for n34 and n39 from Rel-15.\n1.\tUL 7.5 kHz frequency shift for 15 KHz SCS operation.\nThe completion level of the 3GPP Rel-17 work item on LTE\/NR spectrum sharing in Band 34\/n34 and Band 39\/n39 has achieved 100% at RP#93-e (Sep-2021).
