Abstract: Apparatuses, systems, and methods for performing multi-TRP transmissions using techniques for reducing wireless device power consumption. A wireless device may select a downlink signal buffering method for a communication slot. The downlink signal buffering method may be selected from a single antenna panel signal buffering method or a multi-antenna panel signal buffering method. One or more beams for which to perform downlink signal buffering for the communication slot may be selected based at least in part on the downlink signal buffering method selected. Downlink signals may be received from one or more cellular base stations during the communication slot using the selected one or more beams. The downlink signals received using the selected one or more beams may be buffered by the wireless device.

Abstract: A service device (e.g., a user equipment (UE), a new radio NR (gNB), or other network component) as a service provider/consumer can process or generate sidelink communications based on a downlink control information (DCI) for one or more sidelink configured grants that enables resource allocation for the sidelink communication. The device can determine whether to activate, release/deactivate, or request a retransmission for the one or more sidelink configured grants based on one or more fields of a DCI format 3_0 configuration of the DCI.

Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. An example method generates SCI stage 1 and stage 2 for transmitting a transport block (TB) to a user equipment device (UE). The method includes determining the type of sidelink communication for transmitting the TB. An SCI stage 2 format is selected based on the type of sidelink communication. An SCI stage 2 payload is encoded in accordance with the selected SCI stage 2 format. The selected SCI stage 2 format value is encoded in an SCI stage 1 payload. The SCI stage 1 payload and SCI stage 2 payload are transmitted to the UE.

Abstract: This disclosure relates to techniques for configuring and providing physical downlink control channel transmissions with improved reliability in a wireless communication system. A cellular base station may establish a wireless link with a wireless device. The cellular base station may provide downlink control channel configuration information to the wireless device. The downlink control channel configuration information may configure control resources associated with multiple transmission reception points in a search space for the wireless device. The cellular base station may provide downlink control information to the wireless device using control resources included in the search space.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for a UE to request a beam quality measurement procedure. A user equipment device may be configured to perform a method including performing transmitting a request to perform a beam quality measurement procedure for downlink receptions (e.g., a P3 procedure) to a base station/network entity, receiving instructions to perform the beam quality measurement procedure from the base station, and transmitting results of the beam quality measurement procedure to the base station. In some embodiments, transmission of the request may be response to at least one trigger condition and/or detection of a condition at the UE. The request may include an indication of a preferred timing offset. The instructions to perform the beam quality measurement procedure may include a schedule for the beam quality measurement.

Abstract: Techniques for physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH) processing for multiple transmission and reception point (multi-TRP) are disclosed. In some embodiments, determining PDSCH hybrid automatic repeat request-acknowledgement (HARQ-ACK) processing timing may include determining that a user equipment (UE) is configured for single downlink control information (single-DCI) multi-TRP PDSCH operation, determining a first PDSCH and a second PDSCH within a slot, wherein the first PDSCH and the second PDSCH are used in the single-DCI multi-TRP PDSCH operation, and determining a minimum HARQ-ACK processing timing for the first PDSCH and the second PDSCH using one or more symbols of the first PDSCH or one or more symbols of both the first PDSCH and the second PDSCH.

Abstract: Apparatuses, systems, and methods for triggering and signaling of an inter-UE coordination message. A coordinating UE may determine to transmit, to a source UE, a set of resources for the source UE to use for sidelink communications. The determination may be based, at least in part, on an occurrence of at least one condition. The at least one condition may include the coordinating UE receiving a sidelink coordination request message form the source UE, the coordinating UE detecting a resource reservation collision between the source UE and a destination UE, and/or the coordinating UE detecting a half-duplex restriction at the source UE or the destination UE. The coordinating UE may transmit an inter-UE coordination message to the source UE. The inter-UE coordination message may include at least an indication of the set of resources.

Abstract: A user equipment (UE) configured to determine a resource selection window which identifies a first set (e.g., a total set) of candidate resources. The UE may then remove one or more candidate resources from the first set of candidate resources in response to receiving sidelink control information (SCI) from a pedestrian UE with a reservation of the one or more first candidate resources. After removal of these candidate resources from the initial or first set based on their presumed unavailability, the result may be a second set of candidate resources, which may be a subset of the initial or first set for use in communicating with a third UE. The UE may also be configured to remove candidate resources based on a reference signal receive power (RSRP) threshold which can also be adjusted based on a maximum value or a highest priority of the pedestrian UE's data.
