Abstract: A configuration to enable a UE to discard a TPC command for the MCG if there is an overlapping SCG transmission. The apparatus determines that a first PUSCH transmission to an SCG is scheduled to be at least partially concurrent in time with a second PUSCH transmission to a MCG. The apparatus determines whether to receive a TPC command associated with the transmission of the second PUSCH. The apparatus determines whether to discard the TPC command based on when the TPC command is received.

Abstract: A method of wireless communication by a UE (user equipment) includes receiving group-common downlink control information (DCI) indicating coverage-enhancements including channel state information (CSI) report settings for a group of UEs and/or PDCCH repetition. The method also includes reporting CSI in accordance with the coverage-enhanced CSI report settings, which may include report repetition. A method of wireless communication by a base station includes transmitting group-common downlink control information (DCI) indicating coverage-enhanced channel state information (CSI) report settings and/or PDCCH repetition for a group of UEs. The method also includes receiving CSI reports from the group of UEs in accordance with the group-common DCI.

Abstract: Orthogonal frequency-division multiplexing (OFDM) numerologies that maintain symbol boundary alignment while distributing excess cyclic prefixes (CPs) among OFDM symbols. Communication is established using a first sub-carrier spacing (SCS) and a first OFDM numerology, such as an exemplary numerology that distributes excess CP duration among a set of symbols that occupy a time interval within or equal to a corresponding time interval of a symbol of a second OFDM numerology with a second lower SCS. The first SCS may be, e.g., 960 kHz. The second SCS may be, e.g., 120 kHz. Another exemplary OFDM numerology described herein distributes the excess CP as prefix and postfix portions to one of the symbols, such as the first symbol of a set. Communication then proceeds using the first OFDM numerology at the first SCS and, in illustrative examples, using the second OFDM numerology at the second SCS or other OFDM numerologies at other SCSs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information for a plurality of carriers, wherein a set of first carriers of the plurality of carriers are single transmit receive point (single-TRP) carriers and a set of second carriers of the plurality of carriers are multi-TRP carriers; determine, for the plurality of carriers, a distribution that satisfies a per-span capability of the UE, wherein the distribution is of at least one of a plurality of non-overlapped control channel elements or a plurality of blind decodes, wherein the distribution is based at least in part on which carriers, of the plurality of carriers, are single-TRP carriers or multi-TRP carriers; and receive communications on the plurality of carriers in accordance with the distribution. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) or a base station, or both, may generate a set of orthogonal sequences that the UE may use to convey a payload of a number of bits based on a product of an orthogonal matrix and a cell-specific sequence. The UE or the base station, or both, may select a subset of the set of orthogonal sequences based on the number of bits in the payload, and the UE may construct a codebook including the subset of orthogonal sequences. The UE may select an orthogonal sequence from the constructed codebook based on the bits in the payload. The UE may transmit the payload including the number of bits to the base station using the selected orthogonal sequence.

Abstract: A user equipment (UE) may receive a first indication of a configured communication for a first set of symbols. The UE may detect a second indication associated with a second set of symbols. The UE may determine that a direction of the configured communication is different from an indicated direction for the second set of symbols, the second set of symbols at least partially overlapping the first set of symbols. The UE may cancel the configured communication or may communicate the configured communication based at least in part on a physical layer priority of the configured communication and based at least in part on the determination that the direction of the configured communication is different from the indicated direction for the second set of symbols.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a first communication, associated with a first traffic type, or a second communication, associated with a second traffic type, as a selected communication for transmission in an overlapping resource, wherein the first communication and the second communication at least partially overlap in time, and wherein the selection is performed based at least in part on a rule; and transmit the selected communication. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for a UE to measure sounding reference signal (SRS) transmission from another UE. The measurements results may be used, for example, by a serving cell for interference mitigation purposes. For example, the disclosed techniques may include a first UE receiving a configuration for measuring SRS transmitted by a second UE; determining a first bandwidth part (BWP) associated with the configuration; determining a frequency reference point for the SRS to be measured; determining SRS measurement resources, based on one or more parameters of the configuration and the frequency reference point; and measuring SRS transmitted by the second UE on the determined SRS measurement resources.
