Provided is a distributed scheduling method and apparatus for resource allocation for Device-to-Device (D2D) communication. The method includes sending, by a Mobile Station (MS) including data to transmit, a first resource reservation message through at least one first slot among a plurality of slots constituting a resource reservation unit in a resource reservation channel; and when a second resource reservation message sent by another MS is not sensed in a slot with a higher priority than the first slot in the resource reservation unit, transmitting the data through a transmission resource unit corresponding to the resource reservation unit in a data transmission channel. The resource reservation channel corresponds to the transmission resource unit, and the plurality of slots has mutually cyclic priorities.

A method (1900) performed by a first UE for establishing a connection with an access point. The method includes the first UE transmitting (s1904) a random access, RA, preamble to an access point. The method also includes the first UE receiving (s1906) a message transmitted by the access point. The method also includes the first UE determining (s1908) a priority value included in or associated with the message. The method also includes the first UE determining (s1910), based on the priority value, whether or not the message is intended for a UE other than the first UE. The message is a downlink control message that was received within RAR window

An AP multi-link device is disclosed. The AP multi-link device comprises: a transceiver; and a processor. During reception at any one link, when performing transmission at the second link to a non-AP multi-link device operating at a first link and a second link, which are non-simultaneous transmit and receive (STR) links not supported for transmission at another link, the processor determines whether to perform transmission at the second link for the non-AP multi-link device based on whether the non-AP multi-link device is transmitting to the first link.

Embodiments of the present invention disclose a signaling processing method. The method includes: in a downlink subframe set, generating a downlink assignment index (DAI) respectively for a downlink subframe that has a physical downlink control channel (PDCCH) to be sent, where a value of the DAI is generated according to a preset rule and a sequence of carrier first and then subframe; and sending the PDCCH to the user equipment, where the PDCCH carries the DAI. According to the embodiments of the present invention, a transmission delay is shortened and transmission efficiency is improved.

Method and apparatus for transmission of data based on a resource configuration and reception of a response signal are disclosed. The apparatus includes a receiver that receives a resource configuration; and a transmitter that transmits a data based on the resource configuration; wherein the receiver further receives a feedback control signal of the data in a first search space; wherein the resource configuration includes at least one of: a resource for the data, a period of the resource P, a duty cycle of the resource D, a duty period of the resource Ton, a frequency band of the feedback control signal, a transport block size of the data, a modulation and code scheme of the data, a number of repetitions of the feedback control signal R, a first scaling factor G of the first search space, a reduced blind detection indication, and a response window size T to receive the feedback control signal.

Wireless communications systems and methods related to channel occupancy time (COT) sharing among sidelink user equipment devices (UEs) are provided. A first user equipment (UE) determines a channel occupancy time (COT) in a shared radio frequency band for communicating a sidelink with a second UE. The first UE transmits, to the second UE, the sidelink using first resources in the COT, the sidelink comprising COT sharing information for second resources in the COT.

Methods and devices for early CSI reporting by high priority devices, such as for mission critical services. Early reporting can be configured or otherwise indicated by a node for UEs having a particular status, access identity, and/or access category. Reported feedback can include a transmission rank indicator (RI), a precoder matrix indicator (PMI), and a channel quality indicator (CQI) for a codeword.

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for priority access on a shared wireless channel. A priority station (STA), an access point (AP), or a network operator may activate a priority access service. The priority access service provides priority access to authorize priority STAs by allowing them to use more aggressive contention parameters for contention-based access of the wireless channel as compared to other STAs. In some implementations, non-priority STAs may be configured with weakened contention parameters to increase or ensure the likelihood that a priority STA will win contention for access to the wireless channel.

Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of traffic priority-based energy detection threshold adaption in unlicensed band. The method comprises determining a target traffic priority for transmitting data from a first device to a second device; obtaining at least one candidate configuration parameter of an energy detection threshold for channel clearance assessment for the target traffic priority; determining a target configuration parameter for transmitting the data based on the at least one candidate configuration parameter; and transmitting the data to the second device based on the target configuration parameter. In this way, the maximum EDT can be associated with the traffic priority, to facilitate flexible channel access requirement of different uplink traffic priority.

Disclosed herein are method, system, and computer program product embodiments for utilizing multiple traffic identifiers (TIDs) in a single user (SU) transmission. Some embodiments may operate by forming a SU multiple TID data unit that includes first data associated with a first access category and a first TID and second data associated with a second access category and a second TID. Some embodiments may further operate by transmitting the SU multiple TID data unit during a transmission opportunity based on configuration parameters associated with the transmission opportunity.
