Abstract: Radio network Positioning Reference Signals (PRSs) may be managed dynamically via user equipment (UE) requests triggered by measurements in accordance with initial PRS configurations, whereby a UE contacts an Access and Mobility Management Function (AMF) and/or a Location Management Function (LMF). Similarly, an LMF may initiate adjustments in PRS configurations and transmission via communications with base stations, UEs, and/or AMFs. Dynamic signaling of PRS configurations may be achieved via legacy protocols and/or New Radio Positioning Protocol A (NRPPa), for example. A requests from a UE for PRS configuration adjustment may include an indication of a required level of service or of a class of service, for example, and/or an indication of signal measurements, a position estimate, an indication of a capability of the UE.

Abstract: A first apparatus receives, from a second apparatus via a sidelink (SL) transmission, first configuration parameters for a first SL DRX group and second configuration parameters for a second SL DRX group. The first configuration parameters for the first SL DRX group comprise: a common SL DRX parameter set that is shared with the second configuration parameters for the second SL DRX group, and a first dedicated SL DRX configuration parameter set. The first dedicated DRX parameter set comprises: a first on duration at the beginning of a SL DRX cycle of the first apparatus, and a first duration: after an occasion of a PSCCH carrying a first-stage SL control information (SCI) indicates a new SL transmission for a MAC entity of the first apparatus, or after an occasion of a PSSCH carrying a second-stage SCI indicates a new SL transmission for the MAC entity of the first apparatus. The first apparatus determines that the first apparatus is in a first SL active time for receiving information on the SL based on the first configuration parameters for the first SL DRX group, and in a second SL active time for receiving information on the SL based on the configuration parameter for the second SL DRX group.

Abstract: Blind coverage for wireless devices is enhanced varying one or more transmission characteristics of a repeated transmission sent or received by apparatuses, where the repeated transmission includes, for example a Physical Downlink Shared CHannel (PDSCH) and/or a Physical Uplink Shared CHannel (PUSCH) transmissions. Varied characteristics may include a start time for each repetition, a duration for each repetition, a start frequency for each repetition, a bandwidth of each repetition, a number of repetitions for each subframe, and/or a number of repetitions for each slot. Repetitions may be within a Bandwidth Part (BWP) or span multiple BWPs. Repetitions may vary from one to another in start time, start frequency, duration, bandwidth, and slot and subframe patterns. Higher level signalling, such as Radio Resource Control (RRC) signalling may be used to control the inclusion or omission of a DeModulation Reference Signal (DMRS) in repeated transmissions.

Abstract: SL DRX mechanism is used for power savings, to address a number of sidelink non-vehicular sidelink use cases. Methods, systems, and apparatuses, among other things, as described herein may use 1) A sidelink state model to describe the UE behavior for sidelink DRX operation. The DRX operation tailored to each of the sidelink states; 2) Power savings opportunities during SL operation, in addition to stopping PSCCH monitoring; 3) Various DRX models applicable to the sidelink; 4) SL_DRX operation for the SL UnLinked state; or 5) SL DRX operation for the SL_Linked state.

Abstract: Methods, apparatus, and systems are described for assistance information from the UE to network side, e.g., enabling faster decision-making for secondary cell group deactivation in 3GPP MR DC/CA deployments. According to some aspects, instructions for UE behavior upon MR DC/CA secondary cell group activation are provided in a secondary cell group deactivation message to reduce delays for a UE triggered secondary group activation. RRC signaling ambiguities for conditional PSCell addition/ change may be resolved by a synchronization message between a main node and a secondary node to avoid delays and signaling errors.

Abstract: A wireless User Equipment (UE) may indicate to a base station (gNB) that the UE is capable of simultaneously using sidelink resource allocations Mode 1, with scheduling by the gNB, and sidelink resource allocation Mode 2 with scheduling by the UE, and then receive from the gNB, a Medium Access Control (MAC) entity configuration comprising information for Mode 1 and for Mode 2, and Sidelink Radio Bearer (SERB) configurations which may include the mode (Mode 1 or Mode 2) for the SERB. The UE may determine grants for both modes. In case of a grant collision or overlap, the UE may use logical channel priority to select one grant over the other. The UE may change from one mode to another. The MAC entity may take actions related to feedback, BSR reporting, and SR reporting, to manage the transitions.

Abstract: The exchange of resource allocation assistance information between a requester User Equipment (UE) and an assistant UE allows the requester to make better resource allocation decisions. The assistance information may include a blacklist, a whitelist, resource allocation information, a candidate resource set, and measurement information, for example. Both UEs may have an assistance configuration to assist in the exchange of resource allocation assistance information, that may be obtained from a third apparatus, such as a base station. The configuration may include information related to when to trigger assistance, identities of UEs, and types of assistance information, for example. The requester may, based on the assistance information received, modify a candidate resource set at a Medium Access Control (MAC) layer. The requester may, at the MAC layer, determine a configured sidelink grant for a selected destination using assistance information targeting this destination.

Abstract: Methods and apparatuses are described herein for transmission priority, collisions, and sharing in the COT by frame based equipment (FBE). In accordance with one embodiment, a wireless communications device such as an FBE, may conduct two stage channel sensing to avoid collision between other FBEs nodes. The wireless communications device may adjust the energy threshold to reflect a channel access priority. The FBE may conducting continuous and non-continuous second stage channel sensing. The FBE may perform enhanced two stage channel sensing to exploit the remaining portion of the COT. The FBE may store a configuration for the second stage of channel sensing for both the downlink (DL) and uplink (UL).
