    Abstract: A user equipment (UE) is configured to enter a radio resource control (RRC) state with a base station wherein network operations are performed using a main radio (MR), receive a first set of parameters from the base station for wakeup radio (WUR) state operation wherein the UE enables a WUR and powers down the MR to an off or deep sleep state, the first set of parameters including a parameter enabling the WUR state operation and a configuration of WUR reference signaling (WUR-RS), receive a second set of parameters from the base station for WUR setup and a WUR signal (WUR-S) configuration and enter the WUR state from the RRC state, wherein, while in the WUR state, the UE performs uses the WUR including at least one of monitoring for the WUR-S, measuring the WUR-RS, or implementing a WUR discontinuous reception (DRX) cycle for WUR-S and WUR-RS signal monitoring.

    Abstract: Supporting high speed train (HST) schemes at user equipment (UE) (402,404) may include: In response to being within range of a transmission and reception point (TRP) of a plurality of TRPs associated with an HST, decoding a communication received from a network, the communication may include an HST scheme configuration, the HST scheme configuration may include an HST-single frequency network (HST-SFN) without network pre-compensation scheme and an HST-SFN with network pre-compensation scheme (102). At least one of a channel restriction and an environmental restriction associated with the HST scheme configuration may be identified (104). Based on the at least one of the channel restriction and the environmental restriction, the HST scheme configuration may be applied (106).

    Abstract: Triggering an uplink (UL) gap at a base station may include decoding a user equipment (UE) UL gap capability report received from a UE. A radio resource control (RRC) UL gap configuration for transmission to the UE may be encoded. The RRC UL gap configuration may include configuration information associated with at least one of a periodicity, offset, or length. Measurement information received from the UE may be decoded. The measurement information may include at least one of a power headroom value, a PCMAX, f, c value, or a P value. Based on the power headroom value, the PCMAX, f, c value, or the P value, the UL gap configuration may be activated by encoding a medium access control (MAC) control element (MAC CE) for transmission to the UE.

    Abstract: Activating an uplink (UL) gap at a base station may include decoding a user equipment (UE) UL gap capability report received from a UE. A radio resource control (RRC) UL gap configuration may be encoded for transmission to the UE. A power headroom report (PHR) medium access control (MAC) control element (CE) received from the UE may be decoded. The PHR MAC CE may include at least one of a P value or a power management maximum power reduction (P-MPR) value. Decoding the measurement information may include determining that the P value is equal to one or the P-MPR value is greater than zero. Based on determining that the P value is equal to one or the P-MPR value is greater than zero, the UL gap configuration may be implicitly activated.

    Abstract: This disclosure relates to techniques for configuring listen before talk and short control signaling in unlicensed spectrum in a wireless communication system. A wireless device may establish a wireless link with a cellular base station on a cell in unlicensed spectrum. The wireless device may receive listen-before-talk configuration information, where the listen-before-talk configuration information indicates whether listen-before-talk is configured for the wireless link. The wireless device may receive short control signaling configuration information, where the short control signaling configuration information indicates whether short control signaling is enabled for one or more types of control signaling. The wireless device may perform short control signaling with the cellular base station on the wireless link when short control signaling is enabled. The short control signaling performed between the cellular base station and the wireless device may include either or both of uplink transmissions or downlink transmissions.

    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: Apparatuses, systems, and methods for performing dual active protocol stack handovers in a frequency range above 24GHz. 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 24GHz. 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.
