Abstract: Disclosed are embodiments for a request and response signaling between first and second user equipment (UE) via a PC5 link for configuring inter-UE coordination. In some embodiments, request signaling entails a first UE identifying a transmit resource pool of the first UE to be sensed or evaluated by the second UE; instructing the second UE to report information indicating a quantity of resources; and instructing the second UE to evaluate the resources to be reported. In other embodiments, response signaling entails a first UE receiving from the second UE a request signal for inter-UE coordination; indicating a set of one or more resources, in which the set is indicated as corresponding to whitelist, blacklist, or collision list; and providing a validity time for resources indicated.

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: Systems, apparatuses, and methods for notification support in extended discontinuous reception mode. A base station and UE may configure eDRX communication. An indication may be received during the eDRX communication. The network may cache the indication. The network may modify the DRX configuration. The network may use a wake up signal. In response, the UE may receive the indication while achieving power savings from the eDRX configuration.

Abstract: The exemplary embodiments relate to a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. A user equipment (UE) enters into a first state including one of a non-dormant state or a dormant state with a secondary serving cell (SCell) of a network, the SCell being configured to provide either one of a non-dormant bandwidth part (BWP) as a secondary component carrier (SCC) in the non-dormant state or a dormant BWP as an SCC in the dormant state. The UE switches from the first state to a second state including the other one of the non-dormant state or the dormant state, the switch being based on network configuration, a dormancy timer, or a radio condition.

Abstract: An example technique for security key derivation in a wireless system includes: receiving a radio resource control (RRC) suspend message from a first node, the RRC suspend message including a first next hop (NH) chaining counter (NCC) value, entering a RRC inactive state, deriving a first node key based on the first NCC value, generating a first uplink message for transmission in the RRC inactive state based on the first node key, and transmitting the first uplink message to a node while in the RRC inactive state.

Abstract: Techniques discussed herein can facilitate improved security establishment procedures for Vehicle to Everything (V2X) direct connections. Various embodiments are employable at or comprise User Equipment, and can initiate and/or receive V2X security establishment connections wherein a receiving UE can reject the connection based on the initiating UE's capabilities/policy and/or the initiating UE can make the final decision regarding the connection based at least on receiving security policy and capability information from the receiving UE.

Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.
