Abstract: This disclosure relates to techniques for performing wireless communications by a network in communication with a UE that is moving rapidly. The network may adapt communication techniques in response to the CEs motion. For example, reference signals may be transmitted to the UE from additional transmission and reception points and/or using different configurations.

Abstract: A method for Resource Allocation for Msg-3 Transmission on an unlicensed spectrum may include receiving a random access response (RAR) grant comprising a 12-bit frequency domain resource allocation (FDRA) field. If the resource allocation type is type-1 some embodiments may zero padding the FDRA field to interpreting the 12-bit FDRA and determine a starting position of allocated resources where a Scheduled PUSCH Transmission is transmitted in an unlicensed spectrum. Some embodiments may use a virtual Bandwidth Part (BWP) to obtain a starting position and a length of allocated resources.

Abstract: Embodiments are presented herein of apparatuses, systems, baseband processors, and methods for performing vehicle-to-everything sidelink communication. A wireless device receives first control information through a sidelink control channel specifying one or more first time slots for the wireless device to transmit a first acknowledgment message over a sidelink feedback channel. The wireless device transmits second control information through the sidelink control channel specifying one or more second time slots for the wireless device to receive a second acknowledgment message over the sidelink feedback channel. The first and second time slots at least partially overlap, and it is determined whether the first data packet or the second data packet has a higher priority. The acknowledgment message associated with the higher priority data packet is transmitted or received during at least a subset of the overlapping time slots.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to provide SCell activation. In one example, a UE may support carrier aggregation in a high speed mode, such FR1 CA in HST. Serving cells can be particularly configured for the carrier aggregation based on the UE's capability to support carrier aggregation in the high speed mode. Additionally or alternatively, an SCell activation procedure can be performed based on this capability.

Abstract: Improved solutions for reliable physical channel, e.g. Physical Downlink Shared Channel (PDSCH) reception during wireless communications, for example during 3GPP New Radio (NR) communications include continuous channel repetitions that cross slot boundaries, channel repetitions with multiple frequency hops, and joint-repetition channel estimation that uses demodulation reference signals from at least two channel repetitions for the channel estimation. In one aspect, reliable PDSCH reception may have the benefit of aiding target UEs and serving base stations in implementing reliable Multicast and Broadcast Services (MBS).

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.

IPC: H04L5/00
Abstract: A user equipment (UE) communicates with transmission-reception points (TRPs). When the UE generates uplink control information (UCI), it determines a higher layer index (HLI) value to target the UCI to the appropriate TRP. (Possible values of the HLI are associated with the TRPs.) For UCI on Physical Uplink Control Channel (PUCCH), the HLI value may be determined: based on an HLI value configured for a control resource set (CORESET), or for particular Physical Uplink Control Channel (PUCCH) resources; based on UCI type or spatial relation data or an index related to PUCCH resources. For UCI on a configured-grant Physical Uplink Shared Channel (PUSCH), the HLI value may be based on higher layer signals or an indicator relating to channel sounding on spatial relation data. For UCI on MsgA PUSCH in a two-step random access procedure, the HLI value may be based on PUSCH resource unit or PUSCH opportunity.

Abstract: A base station may configure a user equipment (UE) to perform sounding reference signal (SRS) transmissions using an SRS resource set. The SRS resource set may be configured for two or more functions, e.g., functions such as codebook-based SRS transmission, non-codebook-based SRS transmission, antenna port switching, beam management, etc. By enabling the use of such dual function (or multi-function) SRS resource sets, the average data rate associated with configuration transmissions to the UE may be reduced.

Abstract: Apparatuses, systems, and methods for performing uplink transmissions during a dual active protocol stack handover. A wireless device may determine a propagation delay between the wireless device and each of a source cell and a target cell of a dual active protocol stack handover by the wireless device. The wireless device may provide an indication to the source cell of the propagation delay between the wireless device and the source cell, the propagation delay between the wireless device and the target cell, and a propagation delay difference handling capability of the wireless device. The cellular base station that provides the source cell may determine a time division multiplexing pattern for uplink communication for the wireless device during the dual active protocol stack handover based at least in part on the information provided by the wireless device.
