Abstract: Reporting UL Tx DC sub-carrier location information may include decoding a radio resource control (RRC) message received from a base station. The RRC message may comprise a configuration for dynamically reporting uplink (UL) transmit (Tx) direct current (DC) sub-carrier location information. A change associated with at boast one previous UL Tx DC sub-carrier location may be determined to have occurred, thereby creating at least one new UL Tx DC sub-carrier location. In response to determining the change, a medium access control (MAC) control element (MAC CE) may be encoded for transmission to the base station. The MAC CE may include information corresponding to the at least one new UL Tx DC sub-carrier location.

Abstract: Techniques, described herein, include solutions for enabling inter-user equipment (UE) coordination (IUC) using media access control (MAC) control elements (CE). A first UE may send an IUC request to a second UE, and the second UE may respond with a MAC CE that includes IUC information. The IUC information may indicated one or more wireless resources that the first UE may use to communicate with the second UE. The IUC information may also include a time-domain validity for wireless resources, which may include one or more durations of time the wireless resources may be used for communication. The first UE may also implement a latency bound during which the second UE is to respond with the IUC information. In some implementations, discontinuous reception (DRX) may be used by the first and second UEs, and DRX active times of the UEs may be modified or configured to facilitate IUC.

Abstract: A user equipment (UE) configured to receive a first cumulative acknowledgement (ACK) from a protocol stack of the UE at a first time, store the first cumulative ACK in a queue, receive a second cumulative ACK from the protocol stack at a second time, wherein the second time occurs after the first time, store the second cumulative ACK in the queue, discard the first cumulative ACK from the queue based on the second cumulative ACK being received after the first cumulative ACK and encapsulate the second cumulative ACK to form a radio link control (RLC) packet data unit (PDU) that is to be transmitted over the air.

Abstract: Provided is a method for a user equipment (UE). The method includes determining a mobility state of the UE and performing reference signal measurement in a relaxation mode within at least one cell. The mobility state indicates mobility capability of the UE, and, the at least one cell is determined based on the mobility state.

Abstract: A user equipment (UE), next generation NodeB (gNB), or other network component can operate to configure a group configuration message that initiates a plurality of UEs in a coverage area of a non-terrestrial network (NTN) to concurrently transfer communication from a first beam of a first satellite to a second beam of a second satellite. The communications of one or more UEs can be re-directed to the second beam of the second satellite based on downlink control information of the group configuration message.

Abstract: Provided is a method for a user equipment (UE). The UE obtains a cell reselection indication from a network device. The cell reselection indication indicates to the UE whether a terrestrial network (TN) cell or a non-terrestrial network (NTN) cell serves as a camping cell for which the UE performs cell reselection; The UE performs the cell reselection based on the cell reselection indication.

Abstract: A user equipment (UE) device may perform random access to a base station in the context where propagation delay between the base station and the UE device is large. The UE device randomly selects a random access preamble from an available set of preambles. The UE device selects a time slot for transmission of the random access preamble based on a configured correspondence between allowable time slots and subsets of the available set. The UE device transmits the random access preamble to a base station in the selected time slot, with timing advance to compensate for a common delay. Thus, the base station, knowing the configured correspondence, is able to determine the time slot in which the random access preamble was transmitted. The UE device receives a random access response that has been addressed with a Random Access Radio Network Temporary Identifier (RA-RNTI).
