Abstract: Methods, systems, and devices for wireless communications are described. An example method of wireless communication at a user equipment includes receiving a data transmission for each of a plurality of component carriers (CCs) over a wireless channel from a base station, wherein each data transmission is associated with a number of code block groups (CBGs). The method further includes identifying a feedback protocol to apply to the plurality of CCs and selecting a subset of the plurality of CCs for which to report feedback information for the CBGs based at least in part on the feedback protocol. The method may also include generating the feedback information based at least in part on the subset of the plurality of CCs and the feedback protocol and transmitting a feedback message that indicates the feedback information for the subset of the plurality of CCs of the wireless channel to the base station.

Abstract: Methods, systems, and devices for wireless communications are described that support joint allocation for both an uplink message and a downlink message. In some cases, joint downlink control information (DCI) may indicate a time domain resource allocation (TDRA) for a downlink data channel and an uplink data channel. For example, bits of the joint DCI may be configured to indicate TDRA parameters of a downlink data channel (e.g., starting symbol, length value, slot offset, mapping type, timing advance, number of repetitions) and based on the TDRA parameters of the downlink data channel, TDRA parameters for an uplink data channel may be determined by a user equipment (UE) using the joint DCI.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.

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 base station may configure resources on a first communication link for scheduling requests and may transmit an indication of the configured resources over a second communication link to a first device. The first device may relay the indication of the configured resources to a second device via the first communication link. The second device may identify that resources on the first communication link are unavailable for a transmission and may transmit a scheduling request. The first device may receive the scheduling request. The first device may transmit, over the first communication link and based on the scheduling request, an indication of one or more shared channel resources configured by the base station for the transmission. The first device may receive, over the first communication link, the transmission over the one or more shared channel resources.

Abstract: Methods, systems, and devices for wireless communications are described to support relayed sidelink communications. A first device and a base station may communicate via a communication link including a sidelink link between the first device and a second device and a relay link between the second device and the base station. The base station may determine restrictions for the communication link and transmit an indication of the restrictions over the relay link. The restrictions may differentiate data originating from the first device and the second device, restrict the first device to one or more resources, or associate logical channels at the first device with one or more transport block sizes and communication links. The second device may relay the indication of the restrictions to the first device. The first device, the second device, and the base station may communicate over the communication link according to the restrictions.

Abstract: Methods, systems, and devices for wireless communications are described. A base station determines configuration information for a random access procedure, where the configuration information includes a repetition pattern associated with a first message of the random access procedure. A user equipment (UE) receives, from the base station, a configuration message that indicates the configuration information for the random access procedure. The UE determines a repetition pattern associated with a first message of the random access procedure based on the configuration information. The base station receives, from the UE, multiple instances of the first message based on the repetition pattern.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that a plurality of physical downlink shared channel (PDSCH) communications are associated for purposes of demodulation reference signal bundling. The UE may determine whether a phase continuity is to be maintained for the plurality of PDSCH communications based at least in part on respective quasi-co-location assumptions for the plurality of PDSCH communications. The UE may process the plurality of PDSCH communications based at least in part on whether the phase continuity is to be maintained Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. In some cases, a sidelink user equipment (UE) operating in a power saving mode may identify a resource reservation configuration for communicating within a resource pool allocated for sidelink communications. The UE may operate in a first power state of the power saving mode during a sensing window. The sensing window may correspond to a resource selection window of the resource pool. The UE may transition, after the sensing window, from the first power state to a second power state that may consume more power than the first power state. The UE may identify a subset of resources of the resource pool in the resource selection window that are available for sidelink transmission by the UE based on transitioning between the first power state and the second power state.

Abstract: Methods, systems, and devices for wireless communications are described. For a set of scheduled transmission instances of a data communication, a transmitting network node may determine a first spatial filter to apply for a first subset of the scheduled transmission instances configured to provide the data communication and a second spatial filter to apply for a second subset of the scheduled transmission instances configured to allow energy harvesting at an energy harvesting device. In some cases, the transmitting network node may indicate a first quasi co-location (QCL) relation to use for the first subset of the scheduled transmission instances configured to provide the data communication to the network node receiving the data transmissions, and the transmitting network node may indicate a second QCL relation to use for the second subset of the scheduled transmission instances configured to allow energy harvesting to the energy harvesting device.
