Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform respective measurements of one or more demodulation reference signals (DMRSs). Each of the one or more DMRSs may be associated with a repetition of a downlink transmission. Each of the one or more DMRSs may be transmitted on a narrow beam that is located within a wide beam associated with a transmission configuration indication indicated in a grant for the downlink transmission. The UE may transmit an indication of one or more of the respective measurements. Numerous other aspects are provided.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE or a component thereof configured to receive, from a base station, SPS configuration information for broadcast and/or multicast indicating a set of resources configured for feedback, with each transmit (TX) beam of a set of TX beams corresponding to a respective subset of the set of resources. The apparatus may be further configured to receive SPS signaling from the base station via one or more TX beams of the set of TX beams over each of a set of SPS occasions. The apparatus may be further configured to transmit feedback to the base station on one or more subsets of the set of resources respectively corresponding to the one or more TX beams based on the SPS signaling, the feedback indicating one of acknowledgement (ACK) or non-acknowledgement (NACK).

Abstract: Wireless communications systems and methods related to random access signaling are provided. A user equipment (UE) may transmit to a base station (BS) in a frequency band, a random access signal including at least one of a length in time or a length in frequency that is based on a subcarrier spacing (SCS) in the frequency band. The BS may receive the random access signal and transmit a response to the random access signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a downlink control information, a bit map identifying a plurality of feedback indicators for a plurality of uplink transmissions, wherein the plurality of feedback indicators includes more than one acknowledgment and/or negative acknowledgment; and retransmit one or more of the plurality of uplink transmissions based at least in part on receiving the bit map identifying the plurality of feedback indicators. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, based at least in part on the UE being a reduced-capability UE, control information on a reduced capability control resource set (CORESET) at least partially in a reduced capability region of a CORESET region, wherein the reduced capability CORESET is associated with a reduced configuration relative to a CORESET for a non-reduced-capability UE; and communicate in accordance with the control information. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for conveying information via medium access control (MAC) control element (CEs). In some cases, the MAC-CEs may relate to sidelink communications between two user equipments (UEs). A first wireless node may send the first MAC-CE on at least one of a sidelink or a cellular link and provide providing routing information for the first MAC-CE. The routing information may indicate, for example, a source node, a destination node, or a transit route through one or more nodes. The routing information may also indicate whether traffic sent with the first MAC-CE is relayed traffic or traffic originating at the first node.

Abstract: Wireless communications systems and methods related to communicating a serving cell dormancy indication field and acknowledgement. In some implementations, a wireless communication device (e.g., user equipment), may detect a physical downlink control channel (PDCCH) with a secondary cell (Scell) dormancy indication field. The user equipment can change states from an initial state to another state (e.g., a dormancy-like state to a non-dormancy like state) based on detecting Scell indicator field in the PDCCH. The user equipment may also transmit a hybrid-ARQ acknowledgment (HARQ-ACK) in response to the detecting the PDCCH with the Scell dormancy indication field. Other aspects and features are also claimed and described.

Abstract: Aspects are provided in which narrow channels are configured and carrier aggregated with defined channel bandwidths in order to support irregular channel bandwidths that are not a multiple of 5 MHz or other defined bandwidth multiple. An apparatus such as a UE receives, from a base station, a configuration for carrier aggregation for a PCell and one or more SCells. A total bandwidth of the PCell and the one or more SCells is not a defined bandwidth multiple. The apparatus communicates with the base station through the PCell and the one or more SCells. In this way, the available spectrum of wireless operators that include channel bandwidths of irregular size may be supported.
