Abstract: Methods, systems, and devices for wireless communications are described. In an example, a method for wireless communication at a first user equipment (UE) in a wireless communications system is described, including receiving, from a base station, information associated with one or more reconfigurable intelligent surfaces (RISs) in the wireless communications system. The method may also include transmitting a sensing signal to the one or more RISs based at least in part on the information and transmitting an uplink wireless communication to the base station or a second UE using the one or more RISs based at least in part on the sensing. Another method includes determining information associated with one or more RISs in the wireless communications system, transmitting, to a UE, the information associated with the RISs, and communicating with the UE via the RISs based at least in part on the information associated with the RISs.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems implementing beamforming, a neighboring base station may cause interference to a user equipment (UE) served by a different base station. To mitigate unexpected interference, an interference coordination region including time and frequency resources may be configured between the base stations. The interference coordination region may be configured based on long-term information for the base stations and may include one or both of a set of beam-avoidance sub-regions or a set of beam-preference sub-regions for a base station, where each sub-region is associated with a beam index. A base station may schedule a communication beam in the interference coordination region based on a beam-avoidance region (e.g., refraining from using a particular communication beam) or a beam-preference region (e.g., prioritizing a particular communication beam). The base station may transmit a message to a UE using the scheduled communication beam.

Abstract: A user equipment (UE) in communication with a base station may receive downlink control information (DCI) on a physical downlink control channel (PDCCH). The UE may receive a configuration of the PDCCH. The UE may determine a number of downlink PDCCH candidates and a number of uplink PDCCH candidates within a search space based on the configuration, wherein the number of downlink PDCCH candidates is different than the number of uplink PDCCH candidates, and a length of each downlink PDCCH candidate is different than a length of each uplink PDCCH candidate. The UE may blindly decode the search space with each PDCCH candidate as a hypothesis to determine whether any of the downlink PDCCH candidates or uplink PDCCH candidates decode to a DCI format.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. A communication system may include a user equipment (UE) that receives a configuration for contention-free random access (CFRA) and a configuration for contention-based random access (CBRA). The UE determines a first random access resource. The first random access resource maps to one or more beams from a target base station. The UE determines a beam quality associated with the first random access resource. The UE initiates a random access request using the CFRA when the first random access resource is a contention-free resource, and the beam quality of the first random access resource is above a threshold beam quality. The UE initiates the random access request using the CBRA when the first random access resource is the contention-free resource, and the beam quality of the first random access resource is below the threshold beam quality.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to transmit, to a base station, a capability report indicating a capability of the UE to support multi-transmission time interval scheduling. The UE may then receive, from the base station based on the capability report, a first configuration of a first processing mode for the UE that is associated with communications scheduled for a single transmission time interval, and a second configuration of a second processing mode for the UE that is associated with communications scheduled for a scheduling interval spanning a plurality of transmission time intervals. The UE may receive, from the base station, an indication to apply the first processing mode or the second processing mode, and may communicate with the base station based on the indication.

Abstract: Methods, systems, and devices for wireless communications are described that support feedback for multicast communications. A user equipment (UE) in a group of UEs may receive multicast information from a base station in a downlink (DL) transmission scheduled by a DL grant. The DL grant may also indicate a set of uplink resources for the group of UEs to use to transmit feedback. The UE may attempt to decode a message containing the multicast information in the DL transmission. If the UE determines the message was successfully decoded, the UE may send no feedback to the base station. If the UE determines the message was not successfully decoded, the UE may transmit a feedback message to the base station to indicate the message was unsuccessfully decoded. The base station may monitor for the feedback message and determine to retransmit the multicast information if the feedback message is received.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine that a phase-tracking reference signal (PTRS) will not be transmitted based at least in part on a mapping value associated with transmitting the PTRS, and may identify another mapping value associated with transmitting the PTRS, wherein the other mapping value is different from the mapping value. In some aspects, a wireless communication device may identify a symbol in which a demodulation reference signal (DMRS) is to be muted, and may map, based at least in part on a mapping value configured on the wireless communication device, a PTRS relative to the symbol in which the DMRS is to be muted. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive a sounding reference signal (SRS) resource configuration indicating one or more resources over which the UE may transmit one or more SRSs to one or more transmission and reception points (TRPs) within a multi-TRP communications system applying a multi-TRP communication scheme. The SRS resource configuration may configure the one or more resources based on a type of multi-TRP communication scheme being applied by multiple TRPs within the multi-TRP communications system and the UE may support SRS-based channel state information (CSI) acquisition within the multi-TRP communication scheme based on transmitting one or more SRSs over the configured resources. The UE may also receive configurations indicating spatial relations between each configured resource, two or more downlink reference signals, and a demodulation reference signal of an associated downlink transmission.
