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: Aspects herein relate to wireless devices, circuits, and methods for triggering earlier Channel State Information (CSI) feedback, comprising: transmitting, by a wireless device to a wireless station, an indication to provide earlier CSI feedback (e.g., wherein the indication comprises an indication that the wireless device has a reduced capability to receive messages); receiving from the wireless station, in response to the indication, a modified message (e.g., a Downlink Control Information or modified Medium Access Control Random Access Response), wherein the modified message triggers an earlier CSI feedback from the wireless device; transmitting to the wireless station, in response to receiving the modified message, the earlier CSI feedback using a message related to a RACH procedure (e.g., a Msg3); and completing a connection to the wireless station, e.g., in response to a repeated number of initial access messages broadcast from the wireless station and based on the transmitted CSI feedback.

Abstract: An example method for wireless communication includes: transmitting to a base station, via a user device: (1) a capability report for each of a plurality of antenna panels; and (2) an initial antenna panel index; receiving, from the base station, configuration information corresponding to each antenna panel of the plurality of antenna panels; selecting a first antenna panel for a first uplink (UL) transmission to the base station, wherein the first antenna panel corresponds to the antenna panel with the initial antenna panel index; selecting first configuration information corresponding to the selected first antenna panel; and transmitting the first UL transmission to the base station, using the selected first antenna panel and the selected first configuration information. In other aspects, rather than initially receiving configuration information corresponding to each antenna panel, the user device may receive the configuration information for each panel as it is selected for an UL transmission.

Abstract: A user equipment (UE) is configured to handle physical downlink shared channel (PDSCH) transmissions during multi-transmission/reception point (TRP) operation. The UE receives a physical downlink control channel (PDCCH) transmission configured with downlink control information (DCI) in a single-DCI, multi-transmission/reception point (TRP) operation, wherein the DCI schedules reception of a physical downlink shared channel (PDSCH) transmission, determines whether or not a TCI field is configured in the DCI, when the TCI field is not configured in the DCI, determining a default beam based on a control resource set (CORESET) with the lowest ID in the PDCCH and when the TCI field is configured in the DCI, determining whether the TCI field indicates a TCI codepoint includes two TCI states.

Abstract: Improved solutions for reliable physical channel, e.g. Physical Downlink Shared Channel (PDSCH) reception during wireless communications, for example during 3GPP New Radio (NR) communications include continuous channel repetitions that cross slot boundaries, channel repetitions with multiple frequency hops, and joint-repetition channel estimation that uses demodulation reference signals from at least two channel repetitions for the channel estimation. In one aspect, reliable PDSCH reception may have the benefit of aiding target UEs and serving base stations in implementing reliable Multicast and Broadcast Services (MBS).

Abstract: Systems and methods disclosed herein use channel state information (CSI) reports from a user equipment (UE) having additional CSI beyond CSI directly derived according to a current MIMO configuration between a base station and the UE. In some embodiments, a channel quality indicator (CQI) according to a selected layer of a plurality of layers used to receive the MIMO transmission as determined relative to the MIMO transmission is reported. In some embodiments, a precoding matrix indicator (PMI) according to a selected layer of a plurality of layers useable to receive rank 1 transmissions is reported along with a CQI determined according to that layer, or according to a layer used to receive the MIMO transmission as determined relative to the MIMO transmission. In some embodiments, a base station configures a UE to report more fulsome CSI according to each of a plurality of ranks.

Abstract: A UE may coordinate the use of a low Power Wake-Up Radio (LR) and a main radio (MR) to determine a Radio Resource Management (RRM) measurement. The UE may enter a deep sleep state by turning off a MR and turning on a LR. The UE may measure the serving cell quality when in the deep sleep state, and enter a normal state by turning on the MR, when the serving cell quality is less than a threshold. The UE may perform a neighbor cell measurement, when in the normal state when a serving cell measurement meets a criteria.

Abstract: This disclosure relates to techniques for configuring listen before talk and short control signaling in unlicensed spectrum in a wireless communication system. A wireless device may establish a wireless link with a cellular base station on a cell in unlicensed spectrum. The wireless device may receive listen-before-talk configuration information, where the listen-before-talk configuration information indicates whether listen-before-talk is configured for the wireless link. The wireless device may receive short control signaling configuration information, where the short control signaling configuration information indicates whether short control signaling is enabled for one or more types of control signaling. The wireless device may perform short control signaling with the cellular base station on the wireless link when short control signaling is enabled. The short control signaling performed between the cellular base station and the wireless device may include either or both of uplink transmissions or downlink transmissions.
