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, from a base station, signaling indicating a channel state information (CSI) report configuration. The CSI report configuration may indicate a mapping between one or more CSI reference signal (CSI-RS) resources or one or more CSI-RS port groups and one or more antenna panels or antenna subpanels of the base station. The UE may generate CSI feedback based on the mapping. In some cases, the UE may generate the CSI feedback based on multiple hypotheses that correspond to CSI-RS measurements. In some examples, the multiple hypotheses may include a set of hypothesis groups based on one or more antenna panels or antenna subpanels of the base station. The UE may transmit a message reporting the CSI feedback to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may select, from a first path and a second path, a path for an uplink communication associated with at least one of a variable payload size for hybrid automatic repeat request (HARQ) feedback or channel state information (CSI) feedback, wherein the first path is on an uplink of the UE and the second path is on a sidelink of the UE; and transmit the uplink communication on the selected path. 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 downlink control message from a base station scheduling multiple downlink messages and indicating a first offset for communicating a first feedback message of multiple feedback messages including feedback information for the multiple downlink messages. The UE may additionally receive, from the base station, a second offset for communicating the remaining feedback messages of the multiple feedback messages after communicating the first feedback message. The UE may transmit the first feedback message a quantity of resources equal to the first offset after receiving a first downlink message. The UE may then transmit the remaining feedback messages a quantity of resources equal to the second offset after transmitting the first feedback message. Each of the feedback messages may include feedback information for one downlink message.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support allocation of resources for a physical broadcast channel (PBCH) for reduced bandwidth devices. In a first aspect, a method includes monitoring, by a user equipment (UE) configured for reduced bandwidth operation, at least a subset of a first set of time and frequency resources allocated to a synchronization signal block (SSB) for UEs configured for non-reduced bandwidth operation. The SSB includes synchronization signals and a PBCH. The method includes monitoring, by the UE, a second set of time and frequency resources allocated to the PBCH for UEs configured for reduced bandwidth operation. The method includes receiving, by the UE, the synchronization signals and the PBCH within at least the subset of the first set of time and frequency resources and the second set of time and frequency resources. Other aspects and features are also claimed and described.

Abstract: One apparatus may be configured to transmit a set of reference signals on shared resources of a first communication link and a second communication link, the set of reference signals indicating an interference channel on the shared resources. The apparatus may further communicate data or control information on the first communication link following transmission of the set of reference signals. Another apparatus may be configured to detect a signal on shared resources of a first communication link and a second communication link, the signal being indicating an interference channel on the shared resources. The other apparatus may further perform channel estimation on the interference channel based on detecting the signal. The other apparatus may further communicate data or control information on the first communication link based on the channel estimation on the interference channel.

Abstract: Wireless communications systems and methods related to sidelink transmissions from a relay user equipment (UE) to a remote UE are provided. For example, a first UE receives, from a second UE, a configuration indicating a set of resource regions spaced apart from each other in time. The first UE monitors, in one or more of the resource regions, for sidelink control information. The first UE receives, from the second UE based on the monitoring, the sidelink control information in a first resource region of the set of the resource regions. The first UE receives, from the second UE based on the sidelink control information, sidelink data.
