Abstract: When a user equipment (UE) encounters a radio link failure condition, the UE may transmit a radio link failure report to a network. The report may include information defining the radio link monitoring (RLM) resources of a current RLM configuration. The information may take the form of a resource bitmap or a list of resource identifiers/indices. The network may use the information (and radio resource management measurements) to determine whether the radio link failure occurred due to misconfiguration of RLM resources for the UE. In cases where the network does not provide RLM configuration, the UE may omit the bitmap (or list), or populate the bitmap with all zeros, or populate the bitmap (or list) according to a currently active Transmission Configuration Indication (TCI) state, which is indicated by downlink control information (DCI).

Abstract: A first cellular base station transmits a configuration message to a reporting device installed on a high-speed vehicle. The configuration message specifies one or more parameters of a Doppler measurement report. The reporting device performs one or more first Doppler measurements on the first base station and/or one or more second Doppler measurements on a second base station. The reporting device transmits the Doppler measurement report to the first and/or second base stations. The Doppler measurement report may be used by the first and/or second base stations to perform Doppler pre-compensation on transmissions to the reporting device.

Abstract: Systems, methods, and apparatus for paging early indication (PEI) and paging subgrouping are described herein. One described user equipment (UE) includes a set of one or more transceivers and a processor. The processor is configured to transmit, via the set of one or more transceivers, UE assistance information including a preferred time offset between receipt of a PEI by the UE and receipt of a paging occasion (PO) by the UE; transition from a sleep state to an awake state prior to the PO; and monitor for the PEI via the set of one or more transceivers, after transitioning to the awake state.

Abstract: A base station may transmit to a device an indication of codebook subset restriction (CBSR), which includes at least a restriction on a frequency basis. The device may receive the indication of CBSR, and may transmit to the base station channel state information (CSI) according to the received indication of CBSR. The indication of CBSR may also include a restriction on a spatial basis and restrict the device from reporting the CSI based on a subset of the frequency basis in addition to the spatial basis per configuration of the base station. The indication of CBSR may include a separately configured maximum allowed amplitude of a weighting coefficient for the spatial basis and the frequency basis, where the weighting coefficient is associated with a column vector of a precoding matrix used by the base station and the device. The number of frequency bases and the frequency compression units may be determined based on a number of different criteria, for example the number of antennas, the number of subbands, etc.

Abstract: Provided is a method for a user equipment (UE). The UE generates a first information for the UE for transmission to a network device. The first information is associated with a small data transmission (SDT) procedure in an inactive state of the UE. The UE obtains a first configuration information from the network device. The first configuration information is determined with reference to the first information. The UE determines whether to perform the SDT procedure in the inactive state according to the first configuration information. The UE, in response to determining to perform the SDT procedure in the inactive state, performs the SDT procedure in the inactive state according to the first configuration information.
