Abstract: Systems, methods, and devices are provided for performing cell selection or reselection in networks that include earth moving beams. In one example, a method includes receiving, via a satellite, control information transmitted by a base station indicating that a beam associated with a cell ID has been redirected; in response, measuring a beam strength of the redirected beam; and performing cell re-selection based on the measured beam strength.

Abstract: SL-DRX involves both Uu and PC5 interfaces. For an RRC_CONNECTED UE (also referred to as a connected mode UE, or simply connected UE), several SL-DRX enhancements are described in this disclosure to trigger SL DRX and share configurations. Alignment of SL-DRX alignment with Uu-DRX (referred to as Uu/SL DRX alignment or simply alignment) is also described, as an optional feature (since not all schedules can temporally align).

IPC: H04W72/00

Abstract: This disclosure relates to techniques for supporting switching between point to point and point to multipoint delivery with service continuity for broadcast and multicast services in a wireless communication system. A cellular base station and a wireless device may establish a wireless link. The cellular base station may provide information configuring an over the air delivery type with which to receive a broadcast or multicast service, which may be received by the wireless device. The cellular base station may transmit the service using the configured delivery type, and the wireless device may correspondingly receive the service. The cellular base station may provide information configuring the wireless device to switch to a different over the air delivery type, with service continuity. The cellular base station may then transmit the service using that delivery type, and the wireless device may correspondingly receive the service.

IPC: H04W4/40

Abstract: User equipment devices (UEs) may receive multimedia broadcast and multicast service (MBMS) transmissions over a bandwidth part (BWP) specifically allocated for MBMS point-to-multipoint (PTM) transmissions, or over MBMS-specific resources configured for PTM transmissions within a UE-dedicated BWP. The network (e.g. base station) may configure the MBMS-specific BWP for the UE for the PTM transmissions per serving cell. The MBMS-specific BWP may be used for downlink transmissions, and may be cell specific or UE specific per serving cell. The base station may provide MBMS PTM scheduling information per BWP to the UE, may indicate whether a UE-dedicated BWP may be used for PTM scheduling and transmission, and may provide the corresponding scheduling configuration when applicable. The UE may communicate its various capabilities related to MBMS reception and simultaneous reception of PTM and point-to-point (PTP) transmissions to the base station to aid the base station in scheduling communications of the UE.

IPC: H04W88/02

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing sidelink communications among multiple user equipments (UEs). A UE operates according to a periodical discontinuous reception (DRX) cycle that includes a sidelink on-duration period when the UE is in an active state. The UE is in a power saving state outside the sidelink on-duration period. The UE listens to a Physical Sidelink Control Channel (PSCCH) for sidelink communications during the active state. A UE determines the DRX cycle and the sidelink on-duration period of a receiver UE, and sends a message to the receiver UE during one or more slots of the sidelink on-duration period when the receiver UE is in the active state.

Abstract: A user equipment (UE) may operate on a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier. The UE identifies a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier corresponding to a primary secondary cell (PSCell) of a secondary cell group (SCG) for dual connectivity (DC), determines that the dormant BWP is configured in an active state and performing one or more actions corresponding to the dormant BWP.

Abstract: An example technique for security key derivation in a wireless system includes: receiving a radio resource control (RRC) suspend message from a first node, the RRC suspend message including a first next hop (NH) chaining counter (NCC) value, entering a RRC inactive state, deriving a first node key based on the first NCC value, generating a first uplink message for transmission in the RRC inactive state based on the first node key, and transmitting the first uplink message to a node while in the RRC inactive state.

Abstract: A first user equipment (UE) selects a second UE to act as a relay for the first UE. The first UE determines that multiple second UEs are available to operate as a relay for the first UE, wherein the determining is based on measurement data corresponding to communication interfaces between the first UE and each of the second UEs. The first UE selects a second UE from the multiple second UEs and transmits a signal to the second UE.

Abstract: A user equipment (UE) configured to monitor paging occasions of a network. The UE operates in a paging discontinuous reception (DRX) cycle, wherein the DRX cycle includes a paging occasion (PO). The UE determines a location in time for a wake-up signal (WUS) occasion associated with the PO and determines whether to utilize an active mode or a sleep mode during the PO based on an indication included in a WUS received during the WUS occasion.
