Abstract: A method and apparatus for a wireless device of reduced capabilities to access a wireless communication network targeted to operate with wireless device having higher capabilities is disclosed. The device may receive from a base station of the wireless communication network an indication of whether the type of devices that includes the wireless device of reduced capabilities is allowed to access the wireless communication network. The device may transmit to the base station signaling associated with connecting to the base station if the base station indicates that the type of devices with reduced capabilities is allowed to access the wireless communication network. The signaling allows the device to connect to the base station. The device may transmit capability information of the device to the base station. The device may configure its features based on the capability information to communicate with the base station.

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), 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: A base station is configured to transmit wake-up signals to a user equipment to wake-up the UE to receive a page from the base station. The base station transmits one or more synchronization signals, wherein the synchronization signals correspond to a wake-up signal (WUS) that is to be transmitted to a user equipment (UE) operating in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO) and transmits the WUS to the UE during a WUS occasion, wherein the WUS indicates whether the UE is to utilize an active mode or a sleep mode during the PO.

Abstract: Disclosed are methods and systems to coordinate resource allocation between two UEs for sidelink communication. A receiving UE receiving sidelink communication from a transmitting UE may configure coordination resources used to coordinate sidelink communication between the two UEs. The receiving UE may receive from the transmitting UE data indicating resources reserved and intended to be used by the transmitting UE to transmit sidelink data to the receiving UE. The receiving UE may determine a coordination message used to indicate whether the resources reserved by the transmitting UE are available for use by the receiving UE to receive the sidelink data from the transmitting UE. The receiving UE may determine resources from the coordination resources to be used to carry the coordination message and may transmit the coordination message carried on the selected resources to indicate to the transmitting UE whether to use the reserved resources for the sidelink data.
