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: Techniques discussed herein may enable effective cell identification and paging within a non-terrestrial network (NTN). A base station may map logical cell identifiers, corresponding to satellites, to physical cell identifiers, corresponding to physical or geographic cells. The techniques enable cell identification and paging in both Earth-fixed cell scenarios and Earth-moving cell scenarios, and in scenarios where the satellite moves between countries.

IPC: H04W72/00
Abstract: Apparatuses, systems, and methods for enhancement of MBMS transmission reliability. A UE may receive PDCP PDUs via a PTM link from a network. The UE may determine to provide feedback regarding receipt of the PDCP PDUs, e.g., based, at least in part, on an occurrence of a triggering event. The triggering event may be configured by the network and may include the UE receiving a request for feedback from the network, the UE determining that at least one PDCP PDU is missing, the UE determining that a number of missing PDCP PDUs exceeds a threshold, and/or the UE determining that a PDCP reordering window is changing based on expiration of a PDCP reordering timer. The UE may transmit feedback associated with receipt of the PDCP PDUs. The feedback may include an indication of missing PDCP PDUs, e.g., such as an indication of a sequence number associated with missing PDCP PDUs.

Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A base station (BS) may receive from a user equipment (UE) a first buffer status report (BSR) indicating an amount of uplink data buffered by the UE for transmission to the BS, and may subsequently receive a first BSR update message indicating that an additional amount of uplink data has been buffered by the UE subsequent to transmission of the first BSR. The first BSR update message may be received prior to expiration of a timer authorizing transmission of a second BSR following the first BSR. In response, the BS may allocate resources for transmission to the UE, based on the first BSR and the first BSR update message. The BS may provide an uplink grant identifying the allocated resources.

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.
