According to one embodiment of the present disclosure, provided is a method by which a first device performs sidelink communication with a second device. The method can comprise the steps of: determining a first resource for first sidelink transmission; receiving, from the second device or a third device, on an Nth slot, SCI including information related to a second resource for second sidelink transmission; determining, on the basis of a DMRS RSRP threshold value and a DMRS RSRP measurement value of a first PSCCH related to the SCI, whether to reselect the first resource overlapping with the second resource on an N+Kth slot spaced from the Nth slot by K slot length; and transmitting, to the second device, a second PSCCH related to the first sidelink transmission or a PSSCH related to the second PSCCH, on the basis of the determination on whether to reselect.

A user equipment (UE) is described that includes a higher layer processor configured to determine that a high-priority channel collides with a low-priority channel. The high-priority channel and the low-priority channel are uplink channels. The higher layer processor is also configured to drop at least a portion of the low-priority uplink channel. The UE also includes transmitting circuitry configured to transmit the high-priority channel.

An apparatus configured to be employed in a user equipment (UE) associated with a new radio (NR) system is disclosed. The apparatus comprises one or more processors configured to select a first resource from a candidate resource set comprising a plurality of candidate resources within a first resource selection window. In some embodiments, the first resource is to be utilized by the UE for a first transmission of a transport block (TB) over sidelink. In some embodiments, a size of the first resource selection window is derived based on a (pre)configured maximum number of retransmissions of the TB. In some embodiments, the one or more processors is further configured to generate a first transmission signal comprising the first transmission of the TB, to be transmitted over the sidelink using the selected first resource.

This disclosure provides systems, methods, and devices for wireless communication that support physical uplink control channel (PUCCH) resource set determination for multiplexing uplink control information (UCI) messages of different priorities in a wireless communication system. In particular, a user equipment (UE) determines to multiplex a high-priority (HP) UCI message of a first size and a low-priority (LP) UCI message of a second size for a multiplexed PUCCH based on a reference UCI payload size different from a sum of the first and second sizes. The reference UCI payload size is based on a sum of the first size and the second size with a weight factor applied to the first size, second size, or both, or is based on a sum of the first size and a reference second size. The resource set from which the multiplexed PUCCH resource is selected is determined based on the reference UCI payload size.

This disclosure provides systems, methods, and devices for wireless communication that support managing compression and compression indications of a low-priority (LP) uplink control information (UCI) message that is multiplexed with a high-priority (HP) UCI message in a wireless communication system. In particular, a user equipment (UE) determines a compression indication for the LP UCI message, encodes the compression indication jointly with the HP UCI payload, and separately encodes the LP UCI payload. The encoded LP UCI payload is multiplexed with the jointly-encoded compression indication and HP UCI payload in an uplink transmission to a base station. The compression indication includes information related to whether and how the LP UCI has been compressed. The base station decodes the compression indication and then decodes the LP UCI message based on the compression indication.

A method and apparatus for supporting a device-to-device (D2D) communication between user equipments (UEs) are provided. The method of a device-to-device (D2D) communication between user equipments (UEs), the method includes: receiving, at a transmission (Tx) UE, resource assignment information transmitted from an evolved NodeB (eNB), the resource assignment information being associated with a D2D discovery signal to be transmitted in a discovery period; determining, at the Tx UE, that a D2D discovery signal associated with a first discovery type and a D2D discovery signal associated with a second discovery type are to be transmitted in a first subframe included in the discovery period; and in the first subframe, transmitting the D2D discovery signal associated with the second discovery type and dropping the D2D discovery signal associated with the first discovery type.

Management of throughput, link rate, airtime, access, collision probability and other factors influencing performance of a wireless access point configured to wirelessly support two or more networks over the same radio channel and/or antenna is contemplated. The management may be suitable for use with access points operating according to a Distributed Coordination Function (DCF) based on Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) whereby each device desiring airtime executes a random binary backoff procedure or other suitable contention based process before attempting to access the channel.

The present invention relates to a Vehicle-to-X (V2X) communication method performed by a terminal in a wireless communication system. The method comprises: determining priority of information related to the V2X communication; selecting a transmission time interval (TTI) on the basis of the priority; and transmitting the information on the basis of the selected TTI. If the information related to the V2X communication is information having high priority, a first TTI is selected, and if the information related to the V2X communication is information having relatively lower priority than the information having high priority, a second TTI is selected.

A method, apparatus and computer program product are provided herein to provide a Protocol Data Unit (PDU) session priority parameter. For example, a method is provided that comprises identifying a need in a user equipment (UE) for establishing a new protocol data unit PDU session. The method also includes evaluating whether to establish a new PDU session and determining whether to establish a new PDU session based on a PDU session priority parameter when a maximum number of PDU sessions the UE can establish in the network is reached.

A method and apparatus for logical channel prioritization (LCP) based on hybrid automatic repeat request (HARQ) feedback in a wireless communication system is provided. A wireless device selects a first logical channel with a highest priority among multiple logical channels having data available for transmission. When the first logical channel is configured with a hybrid automatic repeat request (HARQ) feedback, the wireless device selects one or more second logical channels configured with the HARQ feedback among the multiple logical channels. When the first logical channel is not configured with HARQ feedback, the wireless device selects one or more second logical channels not configured with the HARQ feedback among the multiple logical channels. The wireless device creates a data unit based on the first logical channel and the one or more second logical channels.
