Abstract: A user equipment (UE) is configured to configured to use multiple beams for transmission or reception. The UE receives, from a base station, at least one medium access control (MAC) control element (CE) that indicates multiple activated transmission configuration indicator (TCI) states, receives, from the base station, at least one downlink control information (DCI) indicating a subset of TCI states of the multiple activated TCI states, wherein the MAC CE and the DCI are part of a TCI configuration, and wherein the subset of TCI states corresponds to multiple transmission and reception points (TRPs) of a wireless network, maps the subset of TCI states to the corresponding multiple TRPs based on the TCI configuration and selects a beam used for transmission or reception based on one mapped TCI state of the mapped subset of TCI states.

Abstract: Systems and methods for using a relay user equipment (UE) to transport data of interest received from a first remote UE to a second remote UE on a UE to UE relay within a wireless communication system are discussed herein. These methods may be performed at Layer 2 of a protocol stack of the wireless communication system. Data packets sent on the UE to UE relay may include an adaptation header including routing information (e.g., Layer 2 addresses, a bearer-specific index, etc.) for the UE to UE relay. An adaptation layer may accordingly be provided within Layer 2 to decode these adaptation headers. In some cases, a per-bearer approach may be used to map between individual direct bearers of a hop by hop path configuration of the UE to UE relay. Embodiments eschewing the adaptation header and instead using logical channel identifiers (LCIDs) to make routing indications are also described.

Abstract: Systems and methods for beam failure recovery (BFR) are disclosed herein. A user equipment (UE) receives downlink (DL) reference signal(s) on corresponding beam(s) from a base station. The UE performs beam failure detection (BFD) on such beams used for user data to determine whether a beam failure has occurred, and candidate beam detection (CBD) on such beams not used for user data to identify candidate beams for recovering from the beam failure. The BFD and the CBD are based on both uplink (UL) channel performance considerations and DL channel performance considerations, as determined using the DL reference signal(s), such that a beam failure may be determined in the UL, the DL, or both, and a candidate beam may be identified for UL, DL, or both. The UE sends a beam failure recovery request BFRQ with this information to the base station, and the system changes beams accordingly.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for reducing interferences for Sounding Reference Signal (SRS) by, for example, one or more of frequency domain interference randomization, code domain interference randomization, or power control. For example, a user equipment (UE) can be configured to determine a comb offset and/or a cyclic shift for each Sounding Reference Signal (SRS) transmission occasion for the UE. The comb offset and/or the cyclic shift change between different SRS transmission occasions of the UE. The UE is further configured to transmit an SRS to the base station using the determined comb offset and/or the determined cyclic shift during the SRS transmission occasion corresponding.

Abstract: A base station is configured to transmit wake-up signals to a user equipment to wake-up the UE to receive a page from the base station. The base station transmits one or more synchronization signals, wherein the synchronization signals correspond to a wake-up signal (WUS) that is to be transmitted to a user equipment (UE) operating in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO) and transmits the WUS to the UE during a WUS occasion, wherein the WUS indicates whether the UE is to utilize an active mode or a sleep mode during the PO.
