Abstract: Some aspects of this disclosure include apparatuses and methods for implementing mechanisms for downlink control information between an electronic device (for example, a UE) and a network for cell detection and measurement. For example, some aspects relate to an electronic device including a transceiver and a processor communicatively coupled to the transceiver. The processor monitors one or more paging occasions within a discontinuous repetition cycle (DRX) and can make a determination of one or more paging occasions within the DRX to not monitor. Each paging occasion may include a transmission by the network of downlink control information for one or more paging messages.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for signaling cross-division duplex configurations. One of the methods includes identifying, by a first device and for a first link with a second device, a switch in a first bandwidth part to a second bandwidth part for the first link, the first link associated with a second link having a third bandwidth part; determining, by the first device, whether a bandwidth band between the second bandwidth part and the third bandwidth part satisfies a threshold guard band; and selectively determining to maintain the third bandwidth part for the second link or to switch the third bandwidth part to a fourth bandwidth part for the second link using a result of the determination whether the bandwidth band between the second bandwidth part and the third bandwidth part satisfies the threshold guard band.

Abstract: Techniques for a wireless device to share a Channel Occupancy Time (COT) in a sidelink (SL) channel are disclosed. The techniques include a method for sharing a Channel Occupancy Time (COT) in a sidelink (SL) channel that includes performing a Clear Channel Assessment (CCA) by a first wireless device to initialize the COT. The first wireless device determines that a portion of the COT may be shared, and transmits to one or more qualifying wireless devices, first Sidelink Control Information (SCI). The first SCI may include a destination identification (ID), an offset, and a SL duration. The destination ID indicates one or more qualifying wireless devices that may share the COT, and the SL duration defines a duration of time available for the one or more qualifying wireless devices to share the COT. The first wireless device may resume transmission in the COT.

Abstract: This disclosure relates to techniques for performing physical uplink control channel repetitions before dedicated physical uplink control channel resource configuration in a wireless communication system. A wireless device may receive configuration information indicating that physical uplink control channel repetition before dedicated physical uplink control channel resource configuration is supported. The wireless device may perform a physical uplink control channel transmission with repetition before dedicated physical uplink control channel resource configuration based at least in part on the configuration information.

Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A user equipment (UE) may receive, from a base station, information indicating that a coverage enhancement mode is supported. The UE may determine whether to enter the coverage enhancement mode based on a downlink signal synchronization block (DL SSB). In response to determining to enter the coverage enhancement mode, the UE may transmit a reserved preamble to the base station to initiate random access for the coverage enhancement mode.

Abstract: Systems and methods provide user equipment (UE) coordinated channel state information (CSI) measurement and reporting. One or both of a first UE and a second UE may perform CSI measurement, but only the first UE sends a CSI report to a base station.

Abstract: Configuring channel state information (CSI) reporting at a user equipment (UE) in a high speed train scenario may include, in response to being within range of a first transmission and reception point (TRP) of a plurality of TRPs associated with an HST, decoding a CSI reporting configuration communication received from a network. The CSI reporting configuration indicating that CSI reporting is to be performed in an HST scenario and being configured for the HST scenario. Measurements based on the decoded CSI reporting configuration received from the network may be performed. A CSI report communication associated with the HST scenario based on the measurements may be encoded for transmission to the network.

Abstract: A user equipment (UE) is configured to use multiple beams for transmission or reception. The UE receives, from a base station, at least one medium access control (MAC) control element (CE) that indicates multiple activated transmission configuration indicator (TCI) states, receives, from the base station, at least one downlink control information (DCI) indicating a subset of TCI states of the multiple activated TCI states, wherein the MAC CE and the DCI are part of a TCI configuration, and wherein the subset of TCI states corresponds to multiple transmission and reception points (TRPs) of a wireless network, maps the subset of TCI states to the corresponding multiple TRPs based on the TCI configuration and selects a beam used for transmission or reception based on one mapped TCI state of the mapped subset of TCI states.

Abstract: Apparatus and methods are provided for a user equipment (UE) to control sidelink power allocation on multiple carriers. The UE determines, from among a plurality of physical sidelink feedback channels (PSFCHs) scheduled for simultaneous transmission on the multiple carriers, prioritized PSFCHs to simultaneously transmit across the multiple carriers based at least in part on a capability of the UE for a maximum number of simultaneous PSFCH transmissions per carrier of the multiple carriers and a total transmission power PCMAX of the UE, where j is an index of a jth-carrier of the multiple carriers. The UE determines allocated transmission power for the prioritized PSFCHs. Then, the UE simultaneously transmits the prioritized PSFCHs on the multiple carriers according to the allocated transmission power.
