Abstract: Peer devices may wirelessly communicate with each other over a bidirectional sidelink logical channel (LCH) through an established bidirectional sidelink radio bearer. An initiating device of the peer devices may dynamically select a logical channel ID for establishing a fully bidirectional or semi-bidirectional SLRB. At least two alternative sidelink radio resource control (PC5-RRC) procedures may ensure the SLRB parameters are configured correctly in the established logical channel. The procedures also allow the network to configure a limited SLRB which is used to couple the SLRB configuration in the direction in which limited traffic (e.g. feedback information such as robust header compression feedback and/or status reports) is transmitted.

Abstract: When a user equipment (UE) encounters a radio link failure condition, the UE may transmit a radio link failure report to a network. The report may include information defining the radio link monitoring (RLM) resources of a current RLM configuration. The information may take the form of a resource bitmap or a list of resource identifiers/indices. The network may use the information (and radio resource management measurements) to determine whether the radio link failure occurred due to misconfiguration of RLM resources for the UE. In cases where the network does not provide RLM configuration, the UE may omit the bitmap (or list), or populate the bitmap with all zeros, or populate the bitmap (or list) according to a currently active Transmission Configuration Indication (TCI) state, which is indicated by downlink control information (DCI).

Abstract: An evaluating user equipment (UE) includes memory and one or more processors communicatively coupled to the memory. The one or more processor are configured to schedule periodic resources with one or more configured feedback-based collision detection parameters, and perform a periodic transmission to one or more receiving UEs. The one or more processors are also configured to collect negative acknowledgement (NACK) statistics for the periodic transmission according to the configured feedback-based collision detection parameters, and selectively perform corrective action based on the collected NACK statistics and at least one of the configured feedback-based collision detection parameters.

Abstract: Methods, systems, apparatuses, and computer programs for enhancing UE handover. In one aspect, the method can include obtaining a request for a handover event from a UE, wherein the request includes at least (i) a request for access to a primary cell group and (ii) data indicating capabilities of the UE, determining, based on the UE capabilities, that the UE is capable of maintaining communication with a secondary cell group of a base station during handover of the UE to the primary cell group of the first base station, generating based on the determined UE capability, a handover command that instructs the UE to maintain communication with the secondary cell group of the base station during handover of the UE to the primary cell group, encoding the generated handover command for transmission to the UE, and transmitting the generated handover command to the UE.

Abstract: A UE may perform a location-based conditional handover (CHO) based on a region information and size parameter associated with a serving cell of a non-terrestrial network (NTN). In time-based CHO, the UE may perform CHO in response to expiration of a network-configured wait time. Alternatively, the UE may perform CHO by randomly selecting a wait time from a network configured time range. The selection may be randomized using a network provided seed or using a cell Radio Network Temporary Identifier (RNTI) value. In elevation-based CHO, the UE may perform CHO in response to the elevation angle of a satellite being less than a network configured threshold. When the UE is configured with multiple cells of the NTN, and the CHO criteria for two or more of the cells are satisfied, the UE may select a target cell for CHO based on network indicated prioritization of the cells.

Abstract: A wireless network may include a base station and user equipment (UE). The UE may transmit uplink (UL) signals to the base station using a dynamically adjustable maximum UL duty cycle. When the UE identifies that a user is in proximity to the UE, the UE may transmit an indicator to the base station. The indicator may identify that a radio-frequency exposure (RFE) event has occurred and/or a suggested maximum UL duty cycle that would allow the UE to satisfy limits on RFE. The base station may limit a UL grant to the UE so that the UE performs subsequent communications using the suggested maximum UL duty cycle or a different maximum UL duty cycle. Coordinating adjustment of UL duty cycle in this way may allow the UE to meet limits on RFE without requiring the UE to perform maximum transmit power level reductions.
