Abstract: Techniques are provided for Wake up signal monitoring in a radio resource control connected (RRC) mode. An example method can include a user equipment (UE) determining capability information associated with wake-up signal (WUS) monitoring, the capability information to include an indication that the UE supports WUS monitoring in a radio resource control (RRC) connected mode. The UE can transmit, to a base station, an indication of the capability. The UE can perform, while in a sleep state in which transmitting and receiving by a main radio is suspended, WUS monitoring to detect a trigger. The UE can transition from the sleep state to the awake state based on the trigger. The UE can monitor for a downlink (DL) transmission in the awake state.

Abstract: A user equipment (UE) in a multiple transmission and reception point (multi-TRP) configuration having simultaneous connections with a first next generation node B (gNB) and at least one second gNB over a same carrier. The UE divides uplink (UL) resources into a plurality of groups, determines a spatial relation and a pathloss reference signal (RS) for each one of the plurality of groups based on a transmission configuration indication (TCI) indicating a quasi-co-location (QCL) source RS for a downlink channel and transmits UL data on the UL resources corresponding to each one of the plurality of groups to a respective one of the first gNB or the at least one second gNB.

Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. An example method generates SCI stage 1 and stage 2 for transmitting a transport block (TB) to a user equipment device (UE). The method includes determining the type of sidelink communication for transmitting the TB. An SCI stage 2 format is selected based on the type of sidelink communication. An SCI stage 2 payload is encoded in accordance with the selected SCI stage 2 format. The selected SCI stage 2 format value is encoded in an SCI stage 1 payload. The SCI stage 1 payload and SCI stage 2 payload are transmitted to the UE.

Abstract: Apparatuses, systems, and methods for positioning reference signals (PRSs) for reduced capacity devices, e.g., in 5G NR systems and beyond. A UE may report, to a network (e.g., to a base station or an LMF) one or more capabilities associated with a positioning procedure for location estimation, e.g., such as a radio frequency retuning time, a parameter indicating a number of bandwidth switches needed by the UE to cover an effective bandwidth and a duration of downlink positioning reference signal symbols, N, that the UE can process in an indicated time period, T, and/or a processing bandwidth, among other parameters. The UE may be configured to transmit a reference signal configuration for the positioning procedure. The reference signal configuration may support frequency hopping with tone-overlap. The reference signal configuration may include an indication of a repetition factor and/or an indication of a frequency hopping factor. In addition, the UE may be configured to perform reference signal measurements, e.g., based on the reference signal configuration.

Abstract: Aspects are described for a user equipment (UE) comprising a low power wake up radio (LP-WUR) and a main radio configured to enable wireless communications with a base station, and a processor communicatively coupled to the LP-WUR and the main radio. The processor is configured to receive a first low power wake up signal (LP-WUS) from the base station; determine that the first LP-WUS corresponds to a cell of the UE; and determine that the first LP-WUS indicates powering on the main radio. The processor is further configured to turn on the main radio and receive a paging message from the base station.
