  • Publication number: 20230413276
    Abstract: A method for WTRU autonomous resource selection may comprise receiving a TX resource pool for D2D communication from a base station. The WTRU may sense one or more resources of the TX resource pool and determine resources for transmission of control information and D2D data, based on the sensing. The WTRU may then transmit, to another WTRU, the control information and the D2D data on the determined resources.

  • Publication number: 20230362941
    Abstract: Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

  • Patent number: 11729691
    Abstract: A method and base station are disclosed. The base station comprises a transceiver and a processor. The base station transmits a system information block (SIB) to a wireless transmit/receive unit (WTRU), wherein the SIB indicates random access transmission uplink resources. After transmitting the SIB, the base station receives a random access preamble from the WTRU. After receiving the random access preamble, the base station receives, using one or more of the uplink resources indicated by the SIB, a first message from the WTRU, wherein the first message includes a first radio network temporary identifier (RNTI) of the WTRU. After receiving the first message, the base station transmits a second message to the WTRU, wherein the second message is derived from a second RNTI, the second RNTI being different than the first RNTI. The base station may be configured to communicate with the WTRU on a plurality of cells.

  • Publication number: 20230209401
    Abstract: Methods and apparatuses are provided for generating a protocol data unit (PDU). A method may include transmitting a medium access control (MAC) protocol data unit (PDU) include information associated with one or more logical channels. The MAC PDU to be transmitted may be assembled by determining an amount of information associated with one of the one or more logical channels to be included in the MAC PDU; and multiplexing one or more complete service data units (SDUs) associated with at least the one of the one or more logical channels into the MAC PDU. On a condition that multiplexing an additional SDU associated with the one of the one or more logical channels would exceed the determined amount of information, the one or more complete SDUs may be multiplexed with a segment of the additional SDU associated with the one of the one or more logical channels and a header indicating that the segment is not a last segment of the additional SDU.

  • Publication number: 20230189350
    Abstract: A method, a wireless transmit/receive unit (WTRU), and a base station are disclosed. The WTRU comprises a receiver, a transmitter, and a processor. The WTRU receives at least one radio resource control (RRC) message indicating an uplink resource for the WTRU and receives grants over first channels associated with the indicated uplink resource. The WTRU transmits uplink data using the indicated uplink resource based on the received grants, and, based on a trigger, deactivates the indicated uplink resource and to stop the reception of grants over the first channels associated with the indicated uplink resource and flush hybrid automatic repeat request (HARQ) buffers associated with the indicated uplink resource. The base station is configured to communicate with the WTRU.

  • Publication number: 20230056813
    Abstract: A wireless transmit/receive unit (WTRU) may receive configuration information indicating a first and a second cell group, and indicating discontinuous reception (DRX) information for them; and may receive a command associated with DRX. The WTRU may perform, based on the command, DRX for cells of the first and second cell groups. A first active time for the first cell group may differ from a second active time for the second cell group. Cells within the first cell group may be active during the first active time; cells within the second cell group may be active during the second. The WTRU may receive a first command to deactivate a first cell of the first cell group, and deactivate the cell based on the first command. The WTRU may receive a first command to reactivate the deactivated first cell, and reactivate the deactivated first cell based on the first command to reactivate.

  • Patent number: 11470551
    Abstract: Method and apparatus for multi-carrier/multi-cell discontinuous reception (DRX)/discontinuous transmission (DTX) operations and activation/deactivation of DRX/DTX are disclosed. A wireless transmit/receive unit (WTRU) may configure at least one state variable for controlling DRX, DTX or both on a group of cells. The WTRU may receive an order for DRX or DTX activation or deactivation. The WTRU may determine a setting for the state variable based on the order. The WTRU may activate or deactivate DRX or DTX based on the setting for the state variable. The group of cells may include all cells within the same frequency band, all cells in a particular frequency or group of frequencies, and all secondary cells associated with a primary cell. The primary cell may be an uplink (UL) or downlink (DL) primary cell. The secondary cells may be UL or DL secondary cells. The WTRU may apply common, group-specific or cell-specific DRX monitoring.
