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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a connection with a base station based at least in part on a synchronization signal block from the base station, wherein the synchronization signal block comprises at least a first synchronization signal. The UE may identify a configuration for a transmission pattern for the first synchronization signal to be transmitted by the base station. The UE may receive one or more instances of the first synchronization signal according to the transmission pattern for the first synchronization signal. The UE may modify the established connection with the base station based at least in part on the received one or more instances of the first synchronization signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a resource for a joint uplink transmission comprising a sounding reference signal and a scheduling request. The UE may receive a grant of a set of resources for an uplink data transmission to a base station. The UE may perform the joint uplink transmission comprising the sounding reference signal and the scheduling request using the resource for the joint uplink transmission in connection with performing the uplink data transmission using the set of resources for the uplink data transmission.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink transmission via at least one of a primary cell, a secondary cell, or a combination thereof. The UE may identify a feedback indication for the downlink transmission. The UE may transmit a first feedback message that includes the feedback indication via the primary cell. The UE may transmit a second feedback message that also includes the feedback indication via the secondary cell.

Abstract: An apparatus for wireless communications includes a processor and a memory that includes instructions. The one or more processors are configured to execute the instructions to control reception, from a base station, of a first downlink signal using a first bandwidth amount that is based on a first frequency range associated with a particular signal transmitted by the base station. The one or more processors are further configured to execute the instructions to initiate transmission, to the base station, of a first uplink signal using a second bandwidth amount. The second bandwidth amount is less than the first bandwidth amount, and the second bandwidth amount is based on a second frequency range associated with an uplink channel.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station may configure a user equipment (UE) with a low latency mode indication that indicates one or more different retransmission timelines or repetition techniques relative to communications that are not associated with the low latency mode indication. The base station may provide the low latency mode indication in downlink control information (DCI) that may include a resource grant for uplink resources for an uplink communication, such as for a UE transmission of pose information of an extended reality (XR) application. The low latency mode indication may signal that no retransmissions of the uplink communication are to be transmitted, that a different retransmission timeline is enabled for low latency mode communications, that retransmissions may happen based on a particular timeline that is determined according to one or more timers, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a dual connectivity configuration for a set of communication links, where at least one communication link of the set includes a sidelink. The UE may transmit a report based on an event associated with the sidelink that triggers the power headroom report. Additionally or alternatively, the UE may identify a carrier aggregation configuration for a set of communication links where at least one communication link of the set is a sidelink. The UE may determine an event associated with the sidelink that triggers a power headroom report, and transmit the power headroom report based on the determined event associated with the sidelink that triggers the power headroom report.

Abstract: Wireless communications systems and methods related to managing sidelink interference on resources shared with a direct link in a wireless communication network are provided. A first user equipment (UE) receives, from a base station (BS), a configuration indicating one or more sidelink interference measurement resources for determining an interference from a sidelink to a direct link of the BS. The first UE communicates, with a second UE, a reference signal in at least a first sidelink interference measurement resource of the one or more sidelink interference measurement resources, where one of the first UE or the second UE is associated with the sidelink, and where the other one of the first UE or the second UE is associated with the direct link.
