Abstract: Disclosed are methods and apparatus for determining time-domain PRACH resources in wireless communication. A New Radio (NR) Physical Random Access Channel (PRACH) configuration comprising an indication of a time-domain PRACH resource type to determine when the UE is allowed to transmit a PRACH preamble and a type of preamble format may be received. Additionally, a PRACH resource based on the received PRACH configuration to transmit the PRACH preamble, wherein the PRACH resource includes RACH resource occasions (ROs) with gaps in between may be determined. Thereafter, a PRACH procedure may be initiated by transmitting the PRACH preamble on a RO based on the determined PRACH resource to a base station (BS).

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform SRS transmission when a UE supports SRS Tx antenna port switching. In an example, a determination is made about whether a scheduled SRS transmission impacts a scheduled DL reception given the SRS Tx antenna port switching. If so, the SRS transmission and/or the DL reception are changed. In a further example, the UE can supports an SRS TA capability in conjunction with the SRS Tx antenna port switching capability. In this example, SRS TA can be applied to a scheduled SRS transmission.

Abstract: The present application relates to devices and components including apparatus, systems, and methods for partial sensing for resource selection, reevaluation, and preemption. In some embodiments: a UE receives configuration information for a resource pool; determines a type of traffic to be transmitted by the UE, the type to include aperiodic traffic or periodic traffic; determines, based on the configuration information and traffic type, first and second values to define a window for contiguous partial sensing; and performs contiguous partial sensing within the window.

Abstract: Technology for an eNodeB to communicate with a user equipment (UE) using a self-contained time division duplex (TDD) subframe within a wireless communication network is disclosed. The eNodeB can process, for transmission to the UE, a DL self-contained time division duplex (TDD) subframe comprising an extended physical downlink shared channel (xPDSCH), an extended physical downlink control channel (xPDCCH), a downlink (DL) spacing signal, and a guard period, wherein the xPDSCH, the xPDCCH, the DL spacing signal, and the guard time are located within the DL self-contained TDD subframe prior to an extended physical uplink control channel (xPUCCH). The eNodeB can process, an uplink (UL) self-contained TDD subframe, received from the UE, having a UL spacing signal located after an extended physical uplink shared channel (xPUSCH).

Abstract: A base station may establish a cellular link with a user equipment (UE) according to a single frequency network scheme. The base station may then determine one or more control resource set (CORESET) transmission configuration indication (TCI) states and transmit signaling to configure the UE with the one or more CORESET TCI states. Additionally or alternatively, the one or more CORESET TCI states may be useable by the UE in performing communications with at least one of a first transmission reception point (TRP) and a second TRP associated with the cellular link with the cellular network.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform measurements on reference signals based on measurement gaps. In an example, a device supports a frequency range that includes frequencies equal to or larger than 52.6 GHz. Measurement gap capability information is used to indicate and/or determine whether a measurement gap is supported for this frequency range. If so, measurement gap configuration can be defined and can include a measurement gap length and/or a measurement gap repetition period defined based on the frequencies being equal to or larger than 52.6 GHz.

Abstract: Apparatuses, systems, and methods for CCA power signaling during COT sharing. A UE may report a maximum EIRP for COT sharing as a UE capability, e.g., for a frequency range between 52.6 and 71 gigahertz. The UE may receive a Pout value for CCA based on the UE capability and may report an actual EIRP used for CCA to acquire the COT. For configured grant COT sharing, the UE may perform a directional LBT with a specific EIRP and beam detection for a transmission burst and report a Pout value for COT sharing based on the directional LBT, e.g., via a configured grant uplink control indication. For dynamic grant COT sharing, the UE may detect that an EIRP exceeds a threshold and report a Pout value for COT sharing via a medium access control (MAC) control element. The threshold may be based on a closed loop power control setting.
