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: Systems, methods, and circuitries are provided for direct transmission of uplink data by an INACTIVE UE using a contention free random access (CFRA) process. In one example, a method, includes, receiving uplink data from transmitted by a user equipment (UE) device while the UE is in a radio resource control (RRC) INACTIVE state, wherein the UE uses a contention-free random access (CFRA) process to transmit the uplink data using a dedicated physical random access channel (PRACH) resource or a dedicated preamble resource (dedicated PRACH/preamble resource) assigned to the UE by a network.

Abstract: Systems and methods for implementing various metrics for in integrated IAB networks are disclosed. A child IAB node may determine metrics regarding one or more of its data flows and report these metrics to an upstream IAB node (that is a parent node and/or an IAB donor). The upstream node may determine a data flow prioritization configuration using these metrics that it either uses itself or sends back to the child IAB node or another IAB node of the IAB network for use there. Metrics discussed include a number of hops metric, an aggregate throughput per BH RLC channel ID (or per routing ID) metric, a fairness index per BH RLC channel ID (or per routing ID) metric, a packet drop metric, and a per-hop latency for aggregated traffic per BH RLC channel ID (or per routing ID) per IAB node metric.

Abstract: Techniques discussed herein can facilitate inactive state transmissions for a User Equipment (UE) via a 4-step or 2-step inactive state RACH process. One example aspect is a UE device, comprising: communication circuitry; and a processor configured to perform operations comprising: in response to a determination to perform a Radio Resource Control (RRC) inactive data transmission: transmitting, via the communication circuitry, a message 1 (Msg1) or a message A (MsgA) preamble based on a Random Access Channel (RACH) configuration for the RRC inactive data transmission; transmitting, via the communication circuitry a message 3 (Msg3) or a MsgA Physical Uplink Shared Channel (PUSCH) comprising uplink (UL) data via configured resources; and receiving, via the communication circuitry, a message 4 (Msg4) or a message B (MsgB) in response to the Msg3 or the MsgA PUSCH.

Abstract: A user equipment (UE) comprising a processor configured to perform the operations that determines an uplink (UL) slot is described. In exemplary embodiments, the UE receives, from a base station, a scaling factor through a first Radio Resource Control (RRC) signal. The UE may further determines an offset through a second RRC signal. In addition, the UE may receive from the base station, downlink control information (DCI) that includes an indication of an initial time gap. Furthermore, the UE may calculate a new time gap by at least applying the scaling factor to the initial time gap and determine a slot of uplink transmission based on at least the new time gap and the offset.

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.
