Abstract: To accommodate a mix of high frequency carriers and lower frequency carriers, a protocol stack may include a radio link control (RLC) entity that allows configuration of status reporting control parameters on per carrier, or per subcarrier spacing. Alternatively, a protocol stack may include two RLC entities, one for handling high frequency carriers, and another for handling lower frequency carriers. (High frequency carriers and lower frequency carriers may be distinguished based on a frequency threshold.) Furthermore, a user equipment may transmit (to the network) an indication of its L2 buffer size. The network may configure the UE and/or control scheduling, to ensure the UE's L2 buffer does not overrun. Alternatively, the UE may indicate that it can support a percentage of a maximum buffer size. The network may configure the UE and/or control scheduling so that the UE's buffer occupancy does not exceed the percentage.

Abstract: A user equipment (UE) operates in a network. The UE receives, from the network, a paging area comprising a plurality of cells of the network. When the UE is in one of a radio resource control (RRC) inactive state or RRC idle state with respect to the network, the UE transmits a message to a first cell of the paging area based on the UE moving into a first coverage area of the first cell from a second coverage area of a second cell of the paging area. The UE then monitors the first cell for a page from the network.

Abstract: A wireless user equipment (UE) device may transmit a random access preamble to a base station, using a physical resource on an uplink signal. After failing to receive an initial transmission of a response message from the base station (BS), the UE device may monitor for one or more retransmissions of the response message. Each of the retransmission may include a corresponding transmission number. As an alternative, each of the retransmissions may be at least partially scrambled using a corresponding Radio Network Temporary Identifier (RNTI). As another alternative, a window for monitoring and RNTI calculation may be extended to include the one or more retransmissions. The successive retransmissions may include the same set of UE-specific payloads, or, a decreasing set of payloads over time as UE devices acknowledge successful receipt of their respective payloads.

Abstract: A user equipment (UE) is configured with a carrier aggregation (CA) functionality and UE connected to a network via a base station that serves as a primary serving cell (PCell) providing a primary component carrier (PCC) to the UE. The UE determines a plurality of bands that are supported by the UE for use in the CA functionality, generates an individual band information element (IE) including band information for the bands, determines at least one representative CA combination having an order, the order indicating a total number of component carriers (CCs), the at least one representative CA combination forming a basis to extrapolate a plurality of CA combinations having the order based on the band information, generates a representative CA combination IE including the at least one representative CA combination and transmits the individual band IE and the representative CA combination IE to the base station.

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: Apparatuses, systems, and methods for reducing wireless device service interruptions. An indication of a disaster condition may be provided to a wireless device. The disaster condition may affect a home public land mobile network of the wireless device. The wireless device may perform cell selection in a manner influenced by the indication of the disaster condition. This may include considering cells associated with a forbidden public land mobile network for the cell selection, or excluding cells associated with the home public land mobile network of the wireless device that are unavailable, for example due to the disaster condition, among various possibilities.

Abstract: A user equipment (UE) includes a transceiver and a processor that is configured to identify a plurality of flows corresponding to data to be sent in an uplink (UL) direction. The processor is also configured to map a subset of the plurality of flows to a logical channel (LCH) of a plurality of LCHs. The processor is further configured to multiplex two or more scheduling requests (SRs) into an integrated SR for requesting one or more physical uplink control channel (PUCCH) resources corresponding to each flow of the subset of the plurality of flows of at least one LCH of the plurality of LCHs. Each SR included in the integrated SR corresponds to an SR for the data associated with at least one flow of the subset of the plurality of flows.
