Abstract: The present disclosure relates to systems and methods for operating transceiver circuitry to transmit or receive signals on various frequency ranges. To do so, an electronic device may determine a receive delay between one or more messages received on different component carriers and may transmit the receive delay to a base station to update how communications are transmitted on one of the component carriers. The update made to at least one of the component carriers may compensate for the receive delay between the different component carriers. Compensating for the receive delay may improve operations that delay downlink communications to reduce a likelihood or stop simultaneous downlink and uplink communications by further adjusting for delays seen at an electronic device when communicating with base stations disposed at a different distances from the electronic device.

Abstract: Techniques for grouping multiple serving component carriers (CCs) are disclosed. In one example, a frequency separation that defines a frequency range from a lower bound frequency to a higher bound frequency for each CC group of a plurality of CC groups may be determined, wherein a difference between the lower bound frequency and the higher bound frequency of each CC group may be equal to the frequency separation. A frequency of a first CC from a collection of CCs may be determined. The first CC may be assigned to a first CC group, of the plurality of CC groups, wherein the first CC group may have a frequency range that includes the frequency of the first CC.

Abstract: A user equipment (UE), or other network device (e.g., next generation NodeB (gNB)) component can operate to process or configure a search space information element (IE) that is configured with at least one of: a transmission configuration indicator (TCI) state identifier (ID) of a TCI, or a physical downlink control channel (PDCCH) repetition field indicating a number of PDCCH repetitions, or a number of UE-specific search space (USS) repetitions for the PDCCH. A UE can perform search space set group (SSSG) beam switching based on one or more TCI states and at least one of: a search space set (SSS) index, an SSSG index, or a beam switching request (BSR) field value. A physical downlink control channel (PDCCH) associated with the search space can be transmitted for beam switching according to a search space information element.

Abstract: The present application relates to devices and components including apparatus, systems, and methods for triggering and using uplink gaps in cellular networks. A method of an embodiment comprises: transmitting, to a base station, an indication of an uplink (UL) gap capability or preference of the UE for body proximity sensing (BPS) or transceiver calibration; activating a UL gap configuration based on an activation command received from a network; and performing operations for BPS or transceiver calibration within a UL gap defined by the UL gap configuration.

Abstract: A technique for wireless communications in a wireless system including: receiving, by a wireless device, a request to perform a pathloss reference signal (PLRS) measurement procedure in an unlicensed band, wherein the wireless device is configured to accumulate a first number of PLRS measurements within a PLRS switching period to perform the PLRS measurement procedure, wherein the first number of PLRS measurements is more than one, measuring, by the wireless device, a second number of PLRS signals during the PLRS switching period, wherein the second number is less than the first number of PLRS measurements within the PLRS switching period, determining, by the wireless device, to extend the PLRS switching period, and listening, by the wireless device, for a PLRS signal during the extended PLRS switching period.

Abstract: Aspects are presented herein of apparatuses, systems, and methods for measurement gap configuration. A cellular network may establish communication with a UE using a first and second cell. The cellular network may configure bandwidth parts (BWPs) for the first and second cell, including a first and second BWP for the first cell and a third and fourth BWP for the second cell. A measurement gap configuration that specifies when the UE is to use a first measurement gap pattern may be provided to the UE. At a first time, the cellular network may communicate with the UE using the first BWP for the first cell and the third BWP for the second cell, based on the first measurement gap pattern. At a second time, the cellular network may communicate with the UE using the second BWP for the first cell based on a modification of the first measurement gap pattern.

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: An approach to communication by a user equipment (UE) in a wireless communication system that includes the UE sending an RRC setup request message including a paging offset value to a base station. The UE receives an RRC setup message from the network node, the RRC setup message including a PS-paging offset value and a PS-P-RNTI value associated with the UE. Energy conservation approaches for use with paging are described, including paging occasion monitor reporting and configuration, paging-offset reporting, the use of a paging monitoring skipping signal, and the use of dynamic TRS triggering for paging reception.
