Abstract: Aspects are provided allowing a base station to configure a UE to accumulate CSI over time for downlink data transmissions, and to transfer the accumulated CSI to a base station in a CSI report in response to a CSI report trigger event, thereby improving efficiency in CSI reporting and subsequent transmission reliability. Initially, the base station configures a CSI report trigger event and sends a plurality of data transmissions to a UE. The UE receives the data transmissions and then identifies the CSI report trigger event. Afterwards, the UE sends a CSI report to the base station including a CSI for each of the data transmissions in response to the CSI report trigger event. The base station may then adjust MCS or other parameters for subsequent data transmissions in response to the CSI report.

Abstract: The apparatus may include a base station and UEs configured to communicate via sidelink communication. The UEs may select transmission resources from a resource pool including first periodic resources for PSFCH and second periodic resources for SL-RS, and rate-match the PSSCH around at least one of the first period resources or the second period resources. The second periodic resources may be shifted in time or canceled based on the first periodic resources. The base station may configure the UEs based on the UEs' capabilities to support the SL-RS and rate-matching the PSSCH around the multiplexed SL-RS and PSFCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive information indicating a reservation or allocation of a resource for transmission of a first signal by another network node, wherein the information identifies whether the network node is to use the resource for transmission of a second signal concurrently with the first signal. The network node may transmit the second signal in the resource based at least in part on the information identifying whether the network node is to use the resource for transmission of the second signal. Numerous other aspects are described.

Abstract: The base station may transmit, to a UE, a configuration of a set of secure RSs for each CC of a set of CCs and at least one RE, and instruct the UE to select a subset of CCs from a set of CCs. The base station and the UE may measure the set of secure RS across the at least one RE, and select the subset of CCs from the set of CCs based on the measurement. The base station and the UE may communicate with each other on the subset of CCs. The base station and the UE may communicate with each other on a first CC of the subset of CCs, and switch the CC from the first CC to a second CC of the subset of CCs to communicate with each other, based on a number of ACKs/NACKs transmitted or a pattern.

Abstract: Wireless communications systems and methods related to energy harvesting services are provided. A first wireless communication device transmitting, to a second wireless communication device, at least one of an energy request or an energy level indication. The first wireless communication device receives, from the second wireless communication device in response to the at least one of the energy request or the energy level indication, an indication of one or more resources for receiving a radio frequency (RF) energy harvesting signal. The first wireless communication device receives, from the second wireless communication device in the one or more resources, the RF energy harvesting signal. The first wireless communication device converts the RF energy harvesting signal to energy.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a first source UE of two or more source UEs, an indication of a first resource allocation for transmitting first data. The UE may transmit, to a second source UE of the two or more source UEs, an indication of a second resource allocation for transmitting second data. The UE may receive, from the first source UE, the first data using the first resource allocation. The UE may receive, from the second source UE, the second data using the second resource allocation. The UE may transmit the first data and the second data to at least one destination UE. Numerous other aspects are described.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for mitigation of crowded UL SPS feedback transmissions. A UE may receive, from a base station, a plurality of SPS PDSCHs in a plurality of DL slots, and determine that at least one UL transmission including HARQ-ACK feedback associated with the plurality of SPS PDSCHs overlaps in time with the plurality of DL slots. Hence, the UE may delay the at least one UL transmission including the HARQ-ACK feedback associated with the plurality of SPS PDSCHs to one or more subsequent slots based on a bitmap indicative of the one or more subsequent slots.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive group common downlink control information (GC-DCI) including an indication of a periodic communication cancellation resource pattern. The UE may selectively cancel a scheduled periodic communication occasion based at least in part on a determination of whether a resource associated with the scheduled periodic communication occasion overlaps with the periodic communication cancellation resource pattern. Numerous other aspects are described.

Abstract: Aspects relate to semi-persistent scheduling (SPS) designs for relay communication in sidelink networks. A scheduling entity, such as a base station and/or sidelink device, may configure an SPS configuration for relaying a packet from a source device to a destination device (e.g., the base station or destination sidelink device) via at least one relay device in a relay sidelink tunnel. SPS information associated with the SPS configuration may be provided to the source device and relay device(s). The SPS information may include, for example, periodic transmit occasions for the source device and the relay device(s). The periodic transmit occasions may include periodic uplink occasions and/or periodic sidelink occasions for groupcast and/or unicast relay transmission. Periodic feedback occasions may further be configured for providing feedback information (e.g., an acknowledgement or negative acknowledgement).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, a sidelink communication via a physical sidelink shared channel (PSSCH). The UE may transmit, to the second UE and based at least in part on the sidelink communication via the PSSCH, hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback and channel state information (CSI) feedback on a single physical sidelink feedback channel (PSFCH) resource. Numerous other aspects are described.
