Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may be configured to monitor a first set of decoding candidates within a first search space for receiving a physical downlink control channel message. A base station may identify downlink data for the user equipment and may transmit a signal to the user equipment. The user equipment may receive the signal within the first search space. In some cases, the signal may include a command for activating a second search space. The user equipment may monitor a second set of decoding candidates within the second search space based on receiving the signal. The user equipment communicate, with the base station, based on monitoring the first set of decoding candidates within the first search space and the second set of decoding candidates within the second search space.

Abstract: Certain aspects of the present disclosure provide techniques for uplink preemption indication. A method for wireless communication by a user equipment (UE) includes receiving at least one ULPI from a base station (BS) indicating, for each of a plurality of sets of uplink resources, a power level the UE can use for one or more uplink transmissions. The UE can determine one or more power levels indicated by the ULPI for resources allocated for the UE for uplink transmission. The allocated resources may include multiple of the sets of uplink resources. The UE can select the power level to use for uplink transmission using the allocated resources based, at least in part, on the determination. The UE sends or drops the one or more uplink transmissions according to the ULPI. A time duration of the plurality of sets of uplink resources can be longer than a configured ULPI monitoring periodicity.

Abstract: Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to bundle reference signals, such as demodulation reference signals (DMRSs), by maintaining one or more coherence properties across DMRSs. A base station may transmit an indication of a DMRS bundling configuration to the UE, and the UE may transmit a DMRS bundling capability indication to the base station. The base station may transmit DCI to the UE, and the UE may determine whether to maintain or alter DMRS bundling (for example, maintain or alter one or more coherence properties) for one or more physical shared channels based on the DCI. The UE may maintain or alter one or more coherence properties of the one or more physical shared channels based on determining whether to maintain DMRS bundling and may transmit the one or more physical shared channels and associated DMRSs to the base station.

Abstract: Apparatus, methods, and computer-readable media for cooperative relay in sidelink networks are disclosed herein. An example method for wireless communication at a first user equipment (UE) includes receiving, from a second UE, a groupcast signal comprising a resource allocation assigned to a plurality of sidelink UEs including the first UE. The example method also includes communicating, with a remote apparatus on a first resource included in the resource allocation, a first relay signal comprising at least a portion of the groupcast signal, in which the first relay signal corresponds to at least a portion of a second relay signal communicated with the remote apparatus on a second resource included in the resource allocation by at least one other sidelink UE of the plurality of sidelink UEs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a grant scheduling a first higher priority channel that has a higher priority than each channel of multiple lower priority channels scheduled for the UE. The UE may drop a first lower priority channel of the multiple lower priority channels that at least partially overlaps in time with the first higher priority channel based on determining that the grant is received prior to a multiplexing deadline for the multiple lower priority channels. The UE may then transmit or receive a first transmission using the first higher priority channel and a second transmission using a second lower priority channel of the multiple lower priority channels based on the dropping.

Abstract: Methods, systems, and devices for increasing the reliability of low latency transmissions are described. For example, multiple control messages and/or multiple data messages may be transmitted for a single transport block. Explicit and/or implicit signaling may be used to support the repetition of control and data transmissions in a low latency environment. For example, explicit signaling may be used to indicate a correspondence between repeated control and/or data messages. Additionally or alternatively, particular configurations may be used to implicitly signal a correspondence between repeated control and/or data messages.

Abstract: Methods, systems, and devices for wireless communications are described that provide for unambiguous mapping between downlink control channel transmissions, downlink shared channel transmissions, and uplink acknowledgment feedback resources. The uplink acknowledgment feedback resource may be located within a same transmission time interval (TTI). A base station may configure codebook-based acknowledgment resources from a user equipment (UE), and feedback delay values may be associated with time domain resources of the downlink shared channel transmissions. In some examples, feedback delay values may be associated with particular search spaces or monitoring occasions of the downlink control channel transmissions that include resource allocations for the downlink shared channel transmissions. A UE using codebook-based acknowledgment feedback resources may thus unambiguously identify uplink resources that are to be used for transmitting the uplink acknowledgment feedback.

Abstract: Wireless communications systems and methods related to transmitting sidelink channel state information (CSI) from one user equipment (UE) to another UE using a L1 signal. A first UE requests a CSI report from a second UE. The first UE sends a reference signal which the second UE measures to determine channel characteristics. The second UE forms a CSI report which includes a rank indicator, a channel quality indicator, and potentially a precoding matrix index indicator. The second UE forms the CSI report at the PHY level. The CSI report is included in reserved field(s) of a second stage sidelink control information (SCI-2). The first UE receives and processes the CSI report at a PHY level.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may transmit, and a user equipment (UE) may receive, a group-common downlink control information (DCI) message, wherein the group-common DCI message includes information identifying at least one communication parameter for a plurality of UEs. The BS and the UE may communicate in accordance with the at least one communication parameter based at least in part on the BS transmitting the group-common DCI message to the plurality of UEs and the UE receiving the group-common DCI message. Numerous other aspects are provided.
