Abstract: Determining RRC processing delays for multi-subscriber identify module (MSIM) user equipments (UEs) may include decoding a capabilities message from a UE that indicates the UE is an MSIM UE that includes at least a first SIM and a second SIM. A communication for the first SIM of the UE may be encoded. The communication may be configured to cause the UE to perform a radio resource control (RRC) procedure. A transmission request received from the UE may be decoded. The transmission request may be associated with the RRC procedure. In response to receiving the transmission request, an uplink (UL) gram may be scheduled for the first SIM of the UE.

Abstract: A user equipment (UE) is grouped into a paging subgroup for the purposes of receiving pages from a network. The UE receives, from the network, a paging configuration for a Radio Resource Control (RRC) idle state or an RRC inactive state paging operation, the paging configuration comprising a paging subgroup identification for the UE and monitors paging occasions based on at least the paging subgroup identification.

Abstract: Techniques, described herein, include solutions for managing hybrid automatic repeat request (HARQ) processes and communications for non-terrestrial networks (NTNs) (e.g., a wireless communication network that includes a satellite network component). A user equipment (UE) may connect to an NTN and determine hybrid automatic repeat request (HARQ) capabilities regarding NTNs. The UE may also communicate a HARQ disablement message to the NTN and communicate with NTN without HARQ procedures. The HARQ disablement message may provide the HARQ disablement capabilities of the UE and/or be a request for the network to disable HARQ. The HARQ disablement message may include a radio resource control (RRC) reconfiguration message and may address HARQ disablement per logical channel identifier (LCID) or dedicated radio bearer (DRB).

Abstract: Techniques are described for improving service continuity for Multicast and Broadcast Services (MBS) communications during handover. Techniques are included for supporting lossless handover and data forwarding during handover for peer-to-multiple (PTM) MBS transmission. Lossless handover may be achieved in part by the user equipment (UE) providing to the target base station an indication of the next packet of the MBS session to be received following an RRC reconfiguration message, and an indication of any MBS packets provided by the source base station prior to the RRC reconfiguration message that were not properly received by the UE. Data forwarding may be performed from the source base station to the target base station if the MBS session was not configured on the target base station prior to the handover. Data forwarding may be omitted if the MBS session was configured on the target base station prior to the handover.

Abstract: Systems and methods for enhancing the use of pre-emptive buffer status reports (pre-BSRs) in wireless communications systems implementing integrated access and backhaul (IAB) networks are disclosed herein. In some cases, an IAB node can re-classify the LCGs of one or more incoming data flows according to such pre-BSR usage. This may involve the use of and extended medium access control (MAC) control element (MAC CE) having more LCG bits than previously contemplated, having sub-LCG bits, or that includes further LCG classification information bits. Other embodiments use a priority index for LCGs in an extended pre-BSR MAC CE. The priority index may include one or more of a priority field, a prioritized bit rate (PBR), and/or a bucket size duration (BSD) that is reported to an IAB donor. Other embodiments leverage the provision of additional grants from an IAB node to a child IAB node to reduce unwanted pre-BSR effects.

Abstract: Reporting UL Tx DC sub-carrier location information may include decoding a radio resource control (RRC) message received from a base station. The RRC message may comprise a configuration for dynamically reporting uplink (UL) transmit (Tx) direct current (DC) sub-carrier location information. A change associated with at boast one previous UL Tx DC sub-carrier location may be determined to have occurred, thereby creating at least one new UL Tx DC sub-carrier location. In response to determining the change, a medium access control (MAC) control element (MAC CE) may be encoded for transmission to the base station. The MAC CE may include information corresponding to the at least one new UL Tx DC sub-carrier location.
