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: Apparatuses, systems, and methods may use an smtc information element or an smtc2-LP information element to calculate timing of a first measurement period to evaluate a serving cell while the UE is in idle mode or inactive mode. Additionally, apparatuses, systems, and methods may use the smtc information element or the smtc2-LP information element to calculate timing of a second measurement period to evaluate intra-frequency cells while the UE is in idle mode or inactive mode.

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: 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.

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.

Abstract: In an example method, a user equipment (UE) device determines an offset length of time associated with transmitting or receiving data over a wireless network. The UE device transmits an indication of the offset length of time to the wireless network. The UE device transmits or receives, during a first time interval, a first portion of data to or from the wireless network though a first wireless link. The UE device transmits or receives, during a second time interval, a second portion of data to or from the wireless network though a second wireless link. An end of first time interval is offset from a beginning of the second time interval by the offset length of time.

Abstract: A method for enhanced autonomous uplink timing adjustment includes determining that a user equipment (UE) is traveling above a predetermined velocity. In response to the determination that the UE is traveling above the predetermined velocity, a maximum aggregate adjustment rate to an uplink timing for the UE and a maximum amount of a magnitude of a timing change to the uplink timing for the UE are determined. The uplink timing for the UE is adjusted based on the maximum aggregate adjustment rate and the maximum amount of the magnitude of the timing change.
