    Abstract: The present disclosure relates to methods and devices for group based Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) measurement and report. The system according to the present disclosure includes at least a network device and a wireless device. A network device (such as a gNB) including at least a first Transmission and Reception Point (TRP) and a second TRP may generate a message used for a wireless device (such as a user equipment (UE)) to perform L1-SINR measurement, wherein the L1-SINR measurement is related to inter-beam interference for beams associated with the first TRP and the second TRP. The message may at least include: (1) a first channel measurement resource (CMR) set including multiple CMRs for the first TRP, and a first interference measurement resource (IMR) set including multiple IMRs for the first TRP, which is corresponding to the first CMR set; (2) a second CMR set including multiple CMRs for the second TRP, and a second IMR set including multiple IMRs for the second TRP, which is corresponding to the second CMR set; and (3) relation information, indicating the relation between the first CMR set and the second IMR set, and the relation between the second CMR set and the first IMR set. The network device sends the message to the wireless device, such that the wireless device may perform the L1-SINR measurement with respect to multiple CMR pairs at least based on the received message and then send corresponding report of the L1-SINR measurement to the network device.

    Abstract: A user equipment (UE) may support concurrent synchronization signal block (SSB) inter-frequency measurement without a measurement gap (MG). The UE may also, or alternatively, support concurrent SSB inter-frequency measurement in intra-band scenarios (e.g., where a target inter-frequency cell and serving cell are on the same band) and/or inter-band scenarios (e.g., where a target inter-frequency cell and serving cell are on the same band). The UE may report concurrent SSB based inter-frequency measurement as a NEEDFORGAP information element (IE), which may include one or more of a variety of parameters regarding UE measurement capabilities. Scheduling restrictions (e.g., restrictions to downlink and uplink communications) are also enabled based on UE measurement capabilities, including scheduling restriction for frequency range 1 (FR1), frequency range 2 (FR2), and cross frequency range scenarios.

    Abstract: Current 5G provisions for wireless communications do not allow for the differentiation of channel access by User Equipments (UEs) with different priorities. Approaches are described by which priority access for UEs in a controlled environment using frame based equipment (FBE), and in particular for different UEs or the same UE that has different configured grants. The approaches are particularly helpful for ultra-reliable low-latency communication (URLLC) UEs. In one approach, the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP), followed by a channel access priority test. In an alternative approach, the UE performs a channel access priority test before the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP). Other approaches include setting the fixed frame period length to different sizes for each UE, using a random number of skipped fixed frame periods, and the gNB configuring UEs with multiple semi-static channel access mode parameters.

    Abstract: Apparatuses, systems, and methods for performing dual active protocol stack handovers in a frequency range above 24 GHz. A UE may transmit an indication to a base station indicating a dual active protocol stack (DAPS) handover capability of the UE corresponding to a frequency range (FR) above 24 GHz. The UE may receive, from a target cell of the one or more cells, a command to perform a DAPS handover from a source cell to the target cell. While performing the DAPS handover and maintaining a data connection with the source cell, the UE may perform measurements on the target cell followed by a physical random access channel (PRACH) procedure. The UE may then receive a source cell release command from the target cell and release the data connection with the source cell.
