Abstract: Inter-cell mobility may include decoding a first radio resource control (RRC) reconfiguration message received from a first cell. The first RRC reconfiguration message may comprise a first portion of configuration information for performing a cell change to a second cell. A cell change message received from the first cell may be decoded. The cell change message may indicate that a cell change to the second cell is to be performed. A cell change acknowledgment may be encoded for transmission to the second cell. A second RRC reconfiguration message received from the second cell may be decoded. The second RRC reconfiguration message may comprise a second portion of configuration information for performing the cell change to the second cell. The second portion of configuration information may comprise a remaining portion of configuration information to perform the cell change to the second cell.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for determining resources for scheduling side-link communications. The resources may be semi-persistent and/or dynamic resources. A user equipment device (UE) may determine a resource map for use in scheduling semi-persistent resources for side-link communications with at least one wireless node. The UE may transmit a resource map request message indicating preferred resource blocks, where each resource block may be defined by a time and a frequency. The UE may receive a confirmation message that may include a report regarding a set of resource blocks. The set of resource blocks may be from the preferred resource blocks included in the resource map request message. The UE may determine, based, at least in part, on the confirmation message, resource blocks to be used for the side-link communications and initiate the side-link communications using the determined resource blocks.

Abstract: Techniques discussed herein can facilitate back-off mechanisms for inter-cell mobility. One example aspect is a baseband processor configured to: receive a unified transmission configuration indicator (TCI) from a first serving cell where the unified TCI is associated with a second serving cell; in response to receiving the unified TCI, transmit an ACK message to the first serving cell; communicate with the second serving cell; configure a time window subsequent to transmission of the ACK message; and perform a fallback operation when a dedicated signaling from the second serving cell is not received within the time window.

Abstract: A user equipment (UE), a baseband processor or other network device can operate in a new radio (NR) unlicensed network can operate to communicate in a UE to UE (U2U) relay path through a first relay UE with another UE as a source or destination UE according to a direct communication request initiating from the source UE. The UE, as a source UE, can also perform the U2U relay reselection based on a measurement report received from a destination UE.

Abstract: Techniques are disclosed relating to reporting channel state information (CSI) when synchronization state is altered. In some embodiments, a UE starts a timing alignment timer (TAT) in response to a time alignment command (TAC) from a cellular network for one or more serving cells. In some embodiments, the UE stores a configuration for a semi-persistent (SP) channel state information (CSI) report for the apparatus over a physical uplink shared channel (PUSCH). In some embodiments, the UE activates the SP-CSI report based on downlink control information (DCI) from the network. In some embodiments, the UE transmits one or more SP-CSI reports according to the configuration. In some embodiments, in response to expiration of the TAT, the UE deactivates all active stored configurations of SP-CSI reports that use the PUSCH and that correspond to the one or more serving cells. In some embodiments, this may avoid collisions with PUSCH transmissions from other UEs, e.g., when the UE returns to an in-sync state.

Abstract: Techniques discussed herein can facilitate transmission and reference signals (RS) associated with layer-1 (L1) operations outside of a configured carrier bandwidth (CBW) of a user equipment (UE). One example aspect is a UE with one or more processors configured to transmit UE capability information. The UE capability information includes a frequency separation threshold, where the frequency separation threshold represents a frequency separation from a CBW of the UE. The one or more processors are further configured to receive a RS within the frequency separation threshold and outside of the CBW, and subsequently perform a L1 operation based on the RS.
