Abstract: Wireless communication systems and methods related to determining a new multimedia broadcast multicast service (MBMS) configuration for a MBMS that is backward compatible with a legacy MBMS configurations. A base station determines a MBMS configuration. The MBMS configuration includes at least one non-optional field that indicates compatibility with a first user equipment (UE) having a first MBMS capability or compatibility with a second UE having a second MBMS capability. The MBMS configuration also includes a sub-carrier spacing indication for a MBMS corresponding to the first MBMS capability or the second MBMS capability. The MBMS configuration is broadcasted to the first UE and the second UE.

Abstract: Disclosed are techniques for wireless communication using satellite access to a wireless network, where a wireless cell supported by a satellite is moving or temporarily fixed. In an aspect, a radio access network (RAN) entity or a user equipment (UE) provides, to a core network entity, an enhanced cell global identifier (CGI), where the enhanced CGI includes at least one field representing a location of the UE. Based on the enhanced CGI, the core network entity determines a location of the UE, and may provide a service to the UE based on the location. A core network may also provide an enhanced CGI to a RAN, e.g., to support wireless emergency alerting to UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: Aspects are provided which allow an apparatus to efficiently indicate downgraded band combinations associated with carrier aggregation (CA) to a base station, in which one or more UE capabilities such as the DL MIMO of certain supported band combinations may be downgraded in exchange for other UE capabilities such as FD-MIMO and 256/1024QAM. The apparatus, which may be a UE, receives a request from a base station for information associated with downgraded band combinations and for information corresponding to at least one UE capability associated with each of the downgraded band combinations. After receiving the request, the UE sends, to the base station, information indicating the downgraded band combinations and the at least one UE capability. The UE may thus report downgraded band combinations for a subset of supported band combinations as requested by the base station, thereby minimizing capability reporting of the UE.

Abstract: Methods, systems, and devices for increasing physical random access channel (PRACH) capacity using orthogonal cover codes (OCCs) in wireless communications systems are described. A base station may transmit a PRACH configuration that indicates PRACH resources for system access, for example, in a system information block (SIB). A user equipment (UE) may receive the PRACH configuration, and may identify PRACH resources that support OCCs for system access. For example, PRACH configurations with small time domain spacing between PRACH resources may support OCCs. The UE may determine whether to transmit random access (RACH) preamble messages using OCCs in the PRACH resources, and may transmit a RACH preamble message to the base station based on the determination. In some cases, the base station may additionally indicate PRACH resources not configured for OCCs, and the UE may determine which set of resources to transmit in based on one or more parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first information element (IE) and a second IE, wherein the first IE indicates whether all UEs that do not support cell-specific reference signal (CRS) muting are barred from a carrier and the second IE indicates whether all UEs that support CRS muting are barred from the carrier; and selectively access the carrier based at least in part on at least one of the first IE or the second IE. In some aspects, a UE may determine whether the UE supports cell-specific reference signal (CRS) muting; and transmit, to a base station, a capability report that indicates whether the UE supports CRS muting. Numerous other aspects are provided.

Abstract: A method, apparatus, and computer-readable medium are provided that improves power savings and reliability of communication for DRX/eDRX modes. A base station may receive an indication from a network entity that a UE is in a DRX/eDRX mode. The base station may configure a WUS mode for the UE corresponding to the DRX mode or the eDRX mode. A UE may receive the WUS mode from the base station. When a UE is configured for relaxed RRM measurements for a first cell and moves to a second cell that supports a relaxed RRM measurement, the UE may return to a regular RRM measurement for a time period. When a UE configured for a WUS mode for a first cell moves to a second cell that supports the WUS mode, the UE may return to the DRX mode or the eDRX mode without the WUS mode for a period of time.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for reporting aperiodic channel quality indicator (A-CQI) in a new Secondary Cell (SCell) state of Long Term Evolution (LTE) carrier aggregation. A User Equipment (UE) receives a request for reporting A-CQI relating to a Scell configured for the UE when the UE is in a first state corresponding to the Scell, the first state designed for a reduced SCell activation latency and to result in the UE using lower power as compared to when the UE is in a second state. The UE, in response to the request, reports the A-CQI for the Scell in accordance with a first A-CQI reporting configuration for the first state which is different from a second A-CQI reporting configuration for the second state.

Abstract: Certain aspects of the present disclosure relate to techniques for secondary cell (SCell) configuration signaling and activation procedures. For example, certain aspects provide a method for configuring a plurality of secondary cells of a base station for a user equipment. The method includes receiving, at the user equipment from the base station, a message including at least one configuration parameter applicable to the plurality of secondary cells. The method further includes configuring the user equipment for the plurality of secondary cells based on the at least one configuration parameter.
