Abstract: Apparatuses, systems, and methods for performing downlink signal reception with antenna panel switching in a wireless communication system. A cellular base station may receive an indication of an antenna panel activation delay from a wireless device. The cellular base station may select a scheduling offset for a transmission to the wireless device based at least in part on the antenna panel activation delay. The scheduling offset may be selected to be at least the length of the antenna panel activation delay if it is expected that the wireless device may perform antenna panel activation to receive the transmission. The cellular base station may schedule the transmission to the wireless device using the selected scheduling offset, and may perform the transmission to the wireless device at the selected scheduling offset after scheduling the transmission to the wireless device.

Abstract: Methods, apparatuses, and systems are disclosed for enhancing timing relationships in non-terrestrial networks (NTNs), e.g., by managing timing offset values and intelligently handling reporting failure relating to timing information reporting. To accommodate increased propagation delay in NTNs, a user equipment (UE) may supplement its timing advance (TA) value with component values representing roundtrip times to the satellite. The UE may maintain both open-loop and closed-loop portions of the TA value, and may report the TA value, or components thereof, to the network for timing synchronization. Methods and systems are also disclosed for failure handling in this reporting process.

Abstract: A user equipment (UE) device comprising a processor configured to perform operations is described. In an exemplary embodiment, the operations include comprising establishing a sidelink session with a transmitting UE; configuring the sidelink session to support coordinated resource selection prior to performing the local sensing; performing a local sensing; receiving a PSCCH and a PSSCH from the transmitting UE. The transmitting UE reserves multiple resources. The processor is further configured to perform operations including determining whether a collision happens among the multiple reserved resources; and transmitting the coordination message to the transmitting UE.

Abstract: Aspects disclosed herein include devices, circuits, and methods for configuring reference signal (RS) measurements for a wireless device, comprising: determining, by a user equipment (UE), that an aperiodic channel state information reference signal (AP-CSI-RS) for Layer 1 reference signal received power (L1-RSRP) measurement occasion is overlapping with one or more Layer 3 (L3) RS measurement occasions; determining that the UE is not able to make measurements for both the AP-CSI-RS for L1-RSRP measurement occasion and the one or more overlapping L3 RS measurement occasions; and prioritizing, by the UE, making the measurement for the AP-CSI-RS for L1-RSRP. Other aspects include a wireless network configured to determine that a UE is not able to make both an AP-CSI-RS for L1-RSRP measurement and a L3 RS measurement in an overlapping measurement occasion and, in response, configuring either the AP-CSI-RS for L1-RSRP or the L3 RS measurement to avoid the overlapping measurement occasion.

Abstract: Performing UCI multiplexing includes generating PUCCH resources Z at an L1 HP procedure and an L1 LP procedure. The L1 HP procedure and the L1 LP procedure results in a plurality of HP PUCCHs and LP PUCCHs, respectively. A modified procedure for Set Q to resources Z is performed with the plurality of HP PUCCHs and LP PUCCHs as inputs. The plurality of HP PUCCHs according to starting symbols is scanned to identify an earliest starting HP PUCCH. A PUCCH from the plurality of LP PUCCHs or HP PUCCHS that overlaps with the earliest starting HP PUCCH is collected. Inter-L1 priority multiplexing is performed on the earliest starting HP PUCCH and the collected PUCCH, which may result in a new HP PUCCH. The new HP PUCCH is inserted into the Set Q. The modified procedure is repeated until there is no overlap among the HP PUCCHs and the LP PUCCHs.

Abstract: Techniques are described relating to hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a HARQ-ACK aggregation window. A User Equipment (UE) may receive control information (e.g., downlink control information (DCI) or radio resource control (RRC) signaling) from a base station including HARQ-ACK codebook information. The HARQ-ACK codebook information may include information on a size of a HARQ-ACK aggregation window. The UE may decode physical downlink shared channel (PDSCH) transmissions and encode corresponding HARQ-ACK feedback using the HARQ-ACK aggregation window based on the control signaling.

Abstract: A method for wireless communication includes: scheduling, by a wireless station, a first uplink (UL) transmission from a wireless device; determining, by the wireless station, a need for a higher priority uplink transmission that uses resources overlapping with the first UL transmission; determining, by the wireless station, a reference region, within which a UL cancellation indication (CI) is to be applied; determining, by the wireless station, a set of UL resources in the reference region for cancellation, wherein at least a subset of the UL resources in the reference region are interlaced; sending, via a downlink control channel, indication of the determined set of UL resources for cancellation (e.g., by indicating particular interlaces and/or particular Physical Resource Blocks within such interlaces that are to be canceled); and receiving, at the wireless station, the higher priority uplink transmission via at least a subset of the determined set of cancelled UL resources.
