Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message indicating that a control resource set for a downlink control channel is associated with a plurality of demodulation reference signal (DMRS) ports. The UE may determine, based at least in part on the configuration message, that a first set of DMRS resource elements in a first symbol of the control resource set correspond to a first DMRS port of the plurality of DMRS ports and a second set of DMRS resource elements in a second symbol of the control resource set correspond to a second DMRS port of the plurality of DMRS ports. The UE may decode the downlink control channel based at least in part on the determining.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support monitoring for intra-slot and intra-slot-group control channel repetitions. The UE may receive a message indicating a respective set of parameters for a first search space set and a second search space set, an indication that the first and second search space sets are linked, and a respective bitmap for each of the search space sets, where the bitmaps include a same quantity of bits. The bitmaps may indicate a quantity of slots and a location of the slots within a group of slots in which a respective search space set exists within the group of slots. As such, the UE may monitor the first and second search space sets based on the respective sets of parameters and the respective bitmaps (e.g., using monitoring occasions associated with each search space set linked based on the bitmaps).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) messages scheduling downlink data transmissions at the UE, where at least one DCI message schedules two or more downlink data transmissions. The UE may determine, based on the DCI messages, a first set of downlink resources associated with a first control resource set (CORESET) group and a second set of downlink resources associated with a second CORESET group. The UE may receive one or more first downlink data transmissions on the first set of downlink resources and one or more second downlink data transmissions on the second set of downlink resources. The UE may communicate using a first set of parameters associated with the first CORESET group and a second set of parameters associated with the second CORESET group.

In some aspects, a user equipment (UE) receive, from a base station (BS), a first downlink control information (DCI) message scheduling an uplink (UL) data transmission, the first DCI message indicating a first value for an UL schedule timing indicator. The UE activates a timer based at least in part on the first value of the UL schedule timing indicator. The UE monitors a downlink control channel based at least in part on the timer. The UE receives, from the BS, a second DCI message indicating UL schedule timing for the UL data transmission based at least in part on the monitoring.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication including random access between a base station and a user equipment (UE). The UE transmits a first random access message to a serving cell. The UE receives a second random access message from the serving cell, in response to the first random access message. The UE transmits a third random access message to one or more transmission reception points of the serving cell in a beam sweep pattern for reception on multiple beams and using resources based on at least one of a beam pool index or a TRP index.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The UE may receive signaling configuring the UE with first and second sounding reference signal (SRS) resource sets. The UE may receive a first downlink control information (DCI) that schedules a first physical uplink shared channel (PUSCH) and indicates a first sounding reference signal (SRS) resource indicator (SRI) value, and a second DCI that schedules a second PUSCH and indicates a second SRI value. The UE may determine SRS resources indicated by the first and second SRI values based on an association between control resource set (CORESET) pool index values and the first and second SRS resource sets. The UE may transmit the first PUSCH indicated by the first SRI value and the second PUSCH indicated by the second SRI value, in accordance with the determination.
