Abstract: A user equipment (UE) may receive a measurement reporting capability request from a base station and further transmit, in response to the request, an indication of the UE’s measurement reporting capability. The UE may further receive, signaling comprising a channel status information (CSI) request trigger from the base station. In response to receiving the CSI request trigger, the UE may transmit a measurement report to the base station, wherein the measurement report may comprise at least one received signal strength indicator (RSSI) measurement.

Abstract: Methods and devices for a UE to multiplex uplink control information (UCI). The UE establishes a connection with a base station. The UE determines whether to multiplex first UCI by first identifying whether intra-priority timing overlap exists between the timing resources of the first UCI and a PUSCH with the same priority. Subsequently, the UE identifies whether inter-priority timing overlap exists between the timing resources of the first UCI and a second PUCCH with a different priority from the first PUCCH. Finally, the UE identifies whether the timing resources of the first UCI overlap with a second PUSCH with a different priority than the first PUCCH. The UE multiplexes the first UCI based on the determination whether to multiplex the first UCI, and transmits the multiplexed first UCI to the base station.

Abstract: Methods, apparatuses, and systems are disclosed for configuring measurement timings in connection with UEs that are capable of signaling whether a measurement gap (MG) is needed to measure a target frequency carrier. For example, a measurement period may be determined for the target frequency carrier based on the UE indicating that it supports per-frequency range (FR) MGs, and determining that the FR of the target frequency carrier does not include any current serving cell(s). If the UE indicates that no MG is needed to measure the target frequency carrier, then the measurement period may be based on an SMTC, and may be further based on a predefined effective measurement gap repetition period (MGRP). If the UE indicates that a MG is needed, then the measurement period may be based on the SMTC, and may be further based on the effective MGRP or a per-UE MGRP.

Abstract: This disclosure relates to techniques for aligning wireless device and cellular network expectations and behavior in conjunction with neighbor cell measurements in a wireless communication system. A wireless device may determine that a reference signal is configured for a neighbor cell measurement when communication with the serving cell is also configured. The wireless device may determine whether the reference signal for the neighbor cell measurement is configured with same or different subcarrier spacing as the communication with the serving cell. The wireless device may select one or more of the reference signal for the neighbor cell measurement or the communication with the serving cell to receive based at least in part on whether the reference signal for the neighbor cell measurement is configured with same or different subcarrier spacing as the communication with the serving cell.

Abstract: Described is an apparatus of an Evolved Node-B (eNB). The apparatus comprises a first circuitry, a second circuitry, and a third circuitry. The first circuitry is operable to associate a first Beam Reference Signal (BRS) for a first Transmit (Tx) beam having a first beamwidth with one or more second BRSes for one or more respectively corresponding second Tx beams having a second beamwidth. The second circuitry is operable to generate a first BRS transmission carrying the first BRS, and to generate one or more second BRS transmissions carrying the one or more respectively corresponding second BRSes. The third circuitry is operable to provide information regarding the first BRS and the second BRSes to the second circuitry.

Abstract: Systems and methods disclosed herein relate to confirmatory signaling sent by a base station for the use of multiple physical uplink control channels (multi-PUSCH) or multiple physical downlink control channels (multi-PDSCH) scheduled in downlink control information (DCI) sent by the base station. Confirmatory signaling may be provided in the form of DCI, or in the form of a physical confirmation indicator channel (PCICH). Confirmatory signaling in DCI may confirm multi-PUSCH/multi-PDSCH scheduling according to one or more UE, and according to one or more CC used by each of the one or more UE using a bitmap. Confirmatory signaling in PCICH may confirm the multi-PUSCH/multi-PDSCH scheduling according to one or more UE. In these embodiments, a symbol for each such UE is spread according to different orthogonal covering codes (OCC), and such spreaded symbols are sent to the UE in a resource element set (RES) of a physical radio block (PRB).

Abstract: Systems and method for using control information to control the relay of signaling between a base station and a user equipment (UE) using a smart repeater (SMR) and/or reconfigurable intelligent surface (RIS) are disclosed herein. In embodiments, a first phase is used by the SMR with a first SS burst from a base station to identify a trained Rx beam to use with the base station, and a second phase receives a second SS burst from the base station and forwards it to a UE using a beam sweep such that the UE is enabled to provide feedback of one SSB of the second SS burst. In other embodiments, an SMR or an RIS is controlled to enable the use of an SS burst to perform a full check of all beam-wise routes between the base station and the UE, enabling feedback of a corresponding SSB selection by the UE.
