Abstract: A method for setting an almost blank subframe (ABS) pattern in a base station of a wireless communication system is disclosed. The method comprises receiving an ABS bitmap pattern from a neighboring base station; setting the ABS pattern of the base station by repeating the ABS bitmap pattern within a previously set number of radio frames; receiving an offset value indicating an application start point of an updated ABS bitmap pattern and an application start of the updated ABS bitmap pattern from the neighboring base station; and setting the ABS pattern of the base station by repeating the updated ABS bitmap pattern from a start subframe of a specific radio frame indicated by the offset value.

Abstract: A method and apparatus for priority handling between a prioritized MAC CE and a SR for data in a wireless communication system is provided. A wireless device determines a prioritized Media Access Control (MAC) Control Element (MAC CE) which is prioritized over a data in Logical Channel Prioritization. The wireless device triggers Scheduling Request (SR) for requesting resource for the data. Based on that Physical Uplink Control Channel (PUCCH) transmission of the triggered SR is overlapped with uplink transmission of a first MAC PDU including the prioritized MAC CE, the wireless device (1) prioritizes the uplink transmission of the first MAC PDU over the PUCCH transmission of the triggered SR transmission, and (2) performs the uplink transmission of the first MAC PDU.

Abstract: A method and apparatus for resource allocation for sidelink configured grant is provided. A a first wireless device receives, from a network, a cell specific Uplink (UL)-Downlink (DL) Time Division Duplex (TDD) configuration and considers that a first slot of a specific sidelink grant occurs in a logical slot determined based on a periodicity. The periodicity is determined based on a number of slots related to sidelink transmission, and the number of slots is determined based on the cell specific UL-DL TDD configuration.

Abstract: A method and apparatus for hybrid automatic repeat request (HARQ) transmission using timers for configured grants and discontinuous reception (DRX) is provided. A first wireless device operating in a wireless communication system receives, from a second wireless device, a sidelink HARQ feedback for a media access control (MAC) protocol data unit (PDU) on a physical sidelink feedback channel (PSFCH), and starts a DRX HARQ round trip time (RTT) timer for a HARQ process ID after end of reception of the sidelink HARQ feedback. Upon expiry of the DRX HARQ RTT timer, the first wireless device starts a DRX retransmission timer, and monitors a physical downlink control channel (PDCCH) carrying a sidelink retransmission grant during an active time including a time interval for which the DRX retransmission timer is running.

Abstract: A method and apparatus for hybrid automatic repeat request (HARQ) feedback based on a communication range and location of devices is provided. A first device (e.g., receiving user equipment in sidelink) receives, from a second device (e.g., transmitting user equipment in sidelink, control information including 1) a communication range, and 2) a location of the second device. The first device determines whether to perform a hybrid automatic repeat request (HARQ) feedback based on whether a distance between a location of the first device for the control information and the location of the second device is smaller or equal to the communication range.

Abstract: A method and appratus for hybrid automatic repeat request (HARQ) transmissions for configured grants (CGs) in a wireless communication system is provided. A first wireless device receives a retransmission resource for a HARQ process identifier (ID) for a CG. When a number of transmissions of a media access control (MAC) protocol data unit (PDU) does not reach to a maximum number of transmissions, the first wireless device performs retransmission of the MAC PDU to a second wireless device by using the retransmission resource. When the number of transmissions of the MAC PDU reaches to the maximum number of transmissions, the first wireless device flushes a HARQ buffer in a sidelink process.

Abstract: The present disclosure relates to channel state reporting in wireless communications. According to an embodiment of the present disclosure, a method performed by a first wireless device in a wireless communication system comprises: establishing a PC5 radio resource control (RRC) connection between the first wireless device and a second wireless device; receiving sidelink control information (SCI) from the second wireless device, wherein the SCI instructs the first wireless device to perform sidelink (SL) - channel state information (CSI) reporting for the PC5 RRC connection; triggering the SL-CSI reporting; and based on that a sidelink resource for the SL-CSI reporting is unavailable and the first wireless device is configured with a mode in which sidelink resources are scheduled by a network, transmitting a signal related to the SL CSI reporting for requesting the sidelink resource to the network.

Abstract: A method and apparatus for triggering of transmission carrier or resource reselection in a wireless communication system is provided. A first wireless device reserves a set of resources comprising at least a first resource and a second resource for sidelink transmission. When (i) the sidelink transmission using the first resource overlaps with an uplink transmission, and (ii) a priority of the uplink transmission is higher than a threshold, the first wireless device clears the first resource from the set of resources, and adds a third resource to the set of resources.

Abstract: A method and apparatus for allocation of lower identifier (ID) and upper identifier (ID) for sidelink transmission in a wireless communication system is provided. A first wireless device (e.g., receiving user equipment (UE)) receives, via upper layer signaling from a second wireless device (e.g., transmitting UE), a lower ID associated with an upper ID and monitors sidelink control information (SCI) based on the lower ID and the upper ID. The first wireless device receives, from the second wireless device, a data unit scheduled by the SCI.
