A computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE). configure the UE for NR communication. The instructions cause the UE to decode sidelink control information (SCI). The SCI includes scheduling information and priority information. The scheduling information indicates time resource assignment and frequency resource assignment for sidelink data communications using a physical sidelink shared channel (PSSCH). The instructions further cause the UE to detect that a transmission (Tx) of a first set of physical sidelink feedback channels (PSFCHs) would overlap in time with a reception (Rx) of a second set of PSFCHs. The first and second sets of PSFCHs include sidelink feedback control information for the sidelink data communications. The instructions further cause transmission of at least one PSFCH from the first set of PSFCHs or the second set of PSFCHs based on the priority information.

The present invention relates to a wireless communication terminal and a wireless communication method for a multi-user EDCA operation, and more particularly, to a wireless communication terminal and a wireless communication method for performing a combination of a legacy EDCA operation and a multi-user EDCA operation. To this end, provided are a wireless communication terminal including: a communication unit; and a processor configured to control transmission and reception of a wireless signal through the communication unit, wherein the processor updates enhanced distributed channel access (EDCA) parameters for channel access, the EDCA parameters being updated based on an EDCA parameter set selected from a first EDCA parameter set and a second EDCA parameter set, and performs channel access based on the updated EDCA parameters and a wireless communication method using the same.

A wireless communication protocol for an access point (AP) multi-link device (MLD) using carrier-sense multiple-access collision avoidance (CSMA/CA) with multi-link operations. Transmit opportunities (TXOPs) are obtained by setting a random number of backoff slots, as a random backoff, for channel contention on each link, and counting down the random backoff on each link independently. When the backoff for the link reaches zero, channel access is obtained and a TXOP duration of reserved on a link whose end time cannot occur later than the latest existing TXOPs of the AP MLD. Numerous variations are described for setting the random number of backoff slots and for reserving the TXOP duration on a link.

An uplink transmission method performed by a terminal includes: receiving, from a base station, at least one DCI for allocating first uplink transmission and second uplink transmission; performing a first LBT procedure for the first uplink transmission, and performing the first uplink transmission when the first LBT procedure is successful; and performing a second LBT procedure for the second uplink transmission, and performing the second uplink transmission when the second LBT procedure is successful, wherein the first uplink transmission and the second uplink transmission are consecutively performed with a time interval longer than a predetermined time.

A wireless device determines a Basic Service Set (BSS) associated with a wireless transmitter by receiving a first frame, determining an address of the first frame, receiving a second frame, and determining, using the address of the first frame, a property of the second frame. Determining the property of the second frame may include determining whether the second frame is intra-BSS frame or an inter-BSS frame. Determining the property of the second frame may be performed by comparing an address of the second frame with the address of the first frame, and the second frame determined to be an intra-BSS frame when the address of the first frame matches the address of the second frame, and determined to be an inter-BSS frame otherwise. The address of the first frame may be a transmitter address (TA).

A dynamic BSS color feature for co-hosted virtual access points is described. An example of a storage medium includes instructions to operations including enabling, by an access point, a dynamic basic service set (BSS) color feature for operation with multiple virtual access points (VAPs) hosted by the access point; switching a parameter of the access point to indicate that no co-hosted BSS is present; assigning a different BSS color to each of the VAPs; performing access point operations, including utilizing the assigned BSS colors for transmissions relating to any of the VAPs; and disabling the dynamic BSS color feature upon occurrence of one or more conditions.

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, to a second UE, a first request message indicating a request to transmit a first sidelink message in a first slot of a sidelink network, and may transmit the first sidelink message in a first data section of the first slot based on transmitting the first request message. The first UE may monitor a first portion of a control section of a second slot of the sidelink network for request messages or response messages. The first UE may transmit a second request message in a portion of the second control section of the second slot designated for scheduling ongoing transmissions, and may transmit a second sidelink message in at least one portion of the second slot based on transmitting the second request message.

A system in wireless network including an Access Point utilizing at least an unlicensed first wireless interface; a Station utilizing at least a first unlicensed wireless interface, transmitting in uplink to the AP; Said at least one STA further includes a secondary wireless interface different from the first unlicensed wireless interface, said STA is configured to, determine that transmission of a message be in a secondary wireless interface of the STA when it is utilized for Reliable and Low Latency Communication RLLC data transmission, generate a message and then transmit the message to a serving AP. Said AP is configured to, when receiving the message from the STA, determine whether information will be generated based on the message received from the STA, generate at least scheduling information and transmit the generated information to the STA.

A method for scheduling transmissions between a controller node, one or more, and one or more uplink nodes comprising: defining one or more non-overlapping downlink and uplink timeslots within a maximum cycle time period; scheduling each of the downlink nodes to listen to receive a respective downlink transmission from a one or multiple radios of the controller node in one of the downlink timeslots on one of a plurality of channels such that none of the downlink transmissions conflict with each other; and scheduling each of the uplink nodes to transmit a respective uplink transmission to a controller radio in one of the uplink timeslots on one of the channels such that none of the uplink transmissions conflict with each other. Each of the downlink nodes is scheduled to listen on a same channel as another if it is possible to do so without any of the respective downlink transmissions conflicting; and each of the uplink nodes is scheduled to transmit on a same channel as another if it is possible to do so without any of the respective uplink transmissions conflicting.

Data including a plurality of blocks is received from a communication apparatus 102. A communication time of retransmission data which is a part of the received data and which is to be retransmitted by the communication apparatus 102 and a communication time of a response signal to be transmitted by the communication apparatus 103 are acquired. The response signal in which a communication reservation time is set is transmitted wherein the communication reservation time includes the communication time of the retransmission data and the communication time of the response signal.
