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: Certain aspects of the present disclosure provide techniques for inter-slot and intra-slot frequency hopping in full duplex. A method performed by a user equipment (UE) includes receiving scheduling information from a network entity, wherein the scheduling information schedules transmission of a plurality of uplink data channel repetitions in a plurality of slots according to a frequency hopping scheme that configures frequency hops between transmissions of repetitions of the plurality of uplink data channel repetitions. The method also includes taking one or more actions related to transmitting, according to the frequency hopping scheme, the plurality of uplink data channel repetitions in the plurality of slots based on the scheduling information.

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, a configuration message that indicates a radio resource allocation and a transmission scheme for one or more first configured grant-small data transfer (CG-SDT) occasions and one or more second CG-SDT occasions. The one or more second CG-SDT occasions are at least partially nested, in time, frequency, or a combination thereof, within the one or more first CG-SDT occasions. The UE may therefore transmit, to the base station, an uplink communication within the one or more first CG-SDT occasions or the one or more second CG-SDT occasions, using the radio resource allocation and the transmission scheme. 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 downlink control information (DCI) that schedules an uplink communication in an uplink frequency band. The UE may transmit, at an uplink frequency within the uplink frequency band, the uplink communication with a power that varies over the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be receive a grant configuration including multiple set of parameters, and the UE may select a set of parameters from the configured grant based on a channel condition. In some examples, the UE may be configured to signal to a network (e.g., a base station) the selected set of parameters and their corresponding parameter values. For example, the UE may be configured to signal the selected set of parameters over semi-static signaling (e.g., radio resource control (RRC) messaging) or dynamic signaling (e.g., medium access control-control element (MAC-CE) messaging, uplink control information (UCI) messaging, or the like). By configuring the UE with multiple set of parameters, the UE may adapt to changing channel conditions, which may provide higher reliability and lower latency for wireless communications, as well as reduce power consumption for the UE.

Abstract: Aspects are provided which allow a UE to provide a CSI report including an expiration time to a base station to reduce the risk of improper scheduling decisions at the base station based on outdated CSI reports. The UE obtains a channel measurement signal from the base station. The UE identifies CSI based on the channel measurement signal and provides a CSI report to the base station including the CSI. The CSI report further includes an expiration time for the CSI report. The base station obtains the CSI report from the UE including the expiration time for the CSI report, and the base station processes downlink data for transmission based on the expiration time in the CSI report.
