Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive a sounding reference signal (SRS) from a first user equipment (UE). The base station may receive a cross-link interference (CLI) report from a second UE based at least in part on the SRS. The base station may determine a CLI from an uplink shared channel based at least in part on a power headroom report for the uplink shared channel received from the first UE and the CLI report received from the second UE. Numerous other aspects are provided.

Abstract: Aspects presented herein may enable reduced capability UEs to support certain type of services with strict delay but limited throughput, while less parallel hardware or computational resources may be used by the reduced capability UEs. In one aspect, a UE reports multiple UE capabilities to a base station, each capability including a set of one or more processing time parameters for a group of HARQ processes. Then the UE receives downlink communication from the base station based on a number of HARQ processes. Then the UE processes the downlink communication from the base station based on a UE capability corresponding to the number of HARQ processes.

Abstract: Aspects presented herein may enable reduced capability UEs to support certain type of services with strict delay but limited throughput, while less parallel hardware or computational resources may be used by the reduced capability UEs. In one aspect, a UE reports, to a base station, a UE capability based on a HARQ process unit (e.g., the UE may indicate to the base station the number of available or maximum HARQ process unit (s) at the UE, etc. ). Then the UE receives downlink communication from the base station. Then the UE processes the downlink communication from the base station and providing HARQ feedback based on the reported UE capability (e.g., based on the number of available HARQ process unit (s) at the UE).

Abstract: A configuration that enables a UE to process a PDSCH DMRS bundle having a higher density of DMRS symbols at a beginning of the PDSCH DMRS bundle. The apparatus receives a PDSCH and DMRS in each slot of a plurality of slots, the DMRS being bundled across the plurality of slots, a first subset of slots of the plurality of slots each having a higher DMRS symbol density of DMRS than a second subset of slots of the plurality of slots, the second subset of slots being subsequent to the first subset of slots. The apparatus decodes each received PDSCH based on at least a subset of the received DMRS.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a first base station transmitting a control message to a user equipment (UE). The control message may include an indication to perform a measurement during one or more resources associated with the first base station and that correspond to a second base station. The UE may measure reference signals transmitting via the beam of the second base station and during the time and frequency resources of the first base station. Based on the measurements, the UE determine an interference status correspond to the beam of the second base station and transmits an indication of the interference status to the first base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate using demodulation reference signal enhancements for control channel repetitions. The UE and the base station may identify a configuration to use to receive or transmit a set of repetitions of control information on a downlink control channel, each repetition of the set of repetitions including one or more symbol periods for an instance of the repeated control information. The base station may transmit, and the UE may receive, a first set of demodulation reference signals in accordance with a first set of parameter values, a second set of demodulation reference signals in accordance with a second set of parameter values, and instances of the control information during the set of repetitions. The UE may decode the control information based on the received signals and configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine that a distance between an end of a first downlink control information (DCI) and a corresponding first physical downlink shared channel (PDSCH) and a distance between an end of a second DCI and a corresponding second PDSCH satisfy a minimum distance threshold for a user equipment (UE). The ends of the DCIs are to be received at the same symbol. The base station may transmit the first DCI, the first PDSCH, the second DCI, and the second PDSCH based at least in part on determining that the distances satisfy the minimum distance threshold. In some aspects, the UE may decode the first and second DCIs in an order that depends on DCI properties. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal mapping each of a plurality of receive port identifiers of the UE to at least one repetition of a multi-repetition downlink transmission, wherein different receive port identifiers are mapped to different repetitions of the multi-repetition downlink transmission. The UE may transmit, based at least in part on the mapping, one or more uplink reference signals using transmission ports corresponding to each receive port identifier that is mapped to at least one repetition of the multi-repetition downlink transmission. The UE may receive the multi-repetition downlink transmission according to the mapping and based at least in part on the one or more uplink reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. Feedback information associated with decoding downlink information may be reported in a first stage and a second stage. A size of the second stage may be restricted by an upper limit associated with an available set of uplink resources for transmitting the feedback information. Limiting the size of the second stage may include reducing a size of second information generated for the second stage, yielding third information for the second stage. The third information may be transmitted with first information generated for the first stage. Limiting the size of the second stage may also include generating second information having a reduced size based on determining that the upper limit may be exceeded. The reduced-size second information may be transmitted with the first information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of a demodulation reference signal (DMRS) bundling set. The UE may determine whether a physical downlink shared channel (PDSCH) received in a slot is bundled with one or more other PDSCHs in the DMRS bundling set based at least in part on downlink control information. The UE may demodulate the PDSCH based at least in part on a same precoder used for the one or more other PDSCHs in the DMRS bundling set. Numerous other aspects are provided.
