Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a report that includes measurements associated with one or more downlink reference signals that are received using a set of candidate downlink beams. The UE may transmit one or more uplink reference signals using a set of candidate uplink beams. The UE may receive, from the base station, information that indicates, among the set of candidate downlink beams and the set of candidate uplink beams, a best uplink beam to use for one or more uplink transmissions. For example, the base station may select the best uplink beam based at least in part on the measurements associated with the one or more downlink reference signals and measurements associated with the one or more uplink reference signals. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a network entity configuring a virtual cell group with multiple cells, where each cell may have a radio frequency spectrum band with a frequency gap that exceeds an operating band threshold. The network entity may transmit additional control signaling including information for the virtual cell group. In some cases, the additional control signaling may include resource allocation information for the virtual cell group, such that the UE may communicate multiple shared channels via different cells in the virtual cell group using the resources indicated in the resource allocation information. In some other cases, the additional control signaling may include a cancellation indication for the virtual cell group, such that the UE may refrain from communicating signals using one or more cells of the virtual cell group.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station as part of a wireless communications system. The UE may identify a configuration for one or more repetitions of an uplink control channel transmission, where each repetition of the one or more repetitions including a first quantity of symbols. The UE may determine a power level for each repetition of the one or more repetitions. The UE may then identify that a second quantity of symbols is available to the UE to transmit a repetition of the one or more repetitions, and the second quantity of symbols may be less than the first quantity of symbols indicated by the configuration. The UE may transmit, to a base station, the repetition on the using the power level.

Abstract: Methods, apparatuses, and computer-readable storage medium for SL communications are provided. An example method may include transmitting, to a second UE, a SL BWP switching request message requesting a switch from a first BWP to a second BWP. The example method may further include receiving, from the second UE, an SL BWP switching decision message confirming the switch from the first BWP to the second BWP. The example method may further include switching from the first BWP to the second BWP upon receiving the SL BWP switching decision message. The example method may further include transmitting, to the second UE, an SL BWP switching confirmation message confirming the switch from the first BWP to the second BWP. The example method may further include reverting back to the first BWP.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving first downlink information, failing to decode a first portion of the first downlink information, transmitting, to a base station (BS), a first response including a negative acknowledgement (NACK) indicating a first decoding failure associated with the first portion of the first downlink information, receiving second downlink information, failing to decode a first portion of the second downlink information, detecting a hybrid automatic repeat request (HARQ) buffer unavailability, determining to discard NACK information associated with the NACK, resetting at least a portion of a HARQ buffer, in response to detecting the HARQ buffer unavailability, by discarding NACK information associated with the NACK, generating a reset NACK indicating the HARQ buffer reset and indicating the NACK information being discarded, and transmitting a second response including the reset NACK to the BS.

Abstract: An aspect of this disclosure relates to a relay node, and a method of wireless communications by the relay node, including attempting to decode first code block groups of a transport block received in a resource allocation and according to a first encoding configuration. The aspects include identifying a symbol in the resource allocation that includes both of a first part of a successfully decoded one, and a first part of an unsuccessfully decoded one, of the plurality of first code block groups, and determining a modified transmit configuration for the symbol. Further, the aspects include encoding a second part of the successfully decoded one according to the first encoding configuration to define a second code block group that is outside of the symbol. Additionally, the aspects include transmitting the transport block including the one or more second code block groups and the symbol according to the modified transmit configuration.

Abstract: Processes, systems, and devices for wireless communications are described. A communication device may monitor a wakeup signal monitoring occasion in an inactive duration of a discontinuous reception (DRX) cycle. The communication device may transmit, in a first active duration of the DRX cycle, a channel state information (CSI) report on one or more resources based on monitoring the wakeup signal monitoring occasion. In some examples, the communication device may transmit an indication that the communication device requests reporting of the CSI report in the first active duration of the DRX cycle. The communication device may, in some examples, receive, in a second active duration of the DRX cycle, control information for the UE based on the CSI report.

Abstract: Techniques are discussed herein identify transmission strategies and to communicate those identified transmission strategies in a transparent communication environment. In some examples, a user equipment (UE) may identify a new transmission strategy for a downlink channel different from a current transmission strategy for the down link channel. The UE may transmit a channel state information (CSI) message that includes an indication of the new transmission strategy identified by the UE. In some examples, a base station may identify the new transmission strategy for the downlink channel. The base station may transmit a codebook subset restriction (CSR) indicator that includes an indication of the new transmission strategy identified by the base station. In some examples, the UE may modify its feedback strategy based on the new transmission strategy.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a first UE may receive an indication of first resources from a second UE. In some examples, the second UE may be a UE configured to receive a transmission from a third UE over the first resources. In some such examples, the first UE may transmit, to a fourth UE, a sidelink transmission over available resources that exclude the first resources. Additionally, or alternatively, the second UE may be a UE that received sidelink control information from the third UE indicating the resources for transmission by the third UE to a fourth UE. In some such examples, the first UE may transmit, to the second UE, a sidelink transmission over available resources that exclude the first resources.
