An access point generates a beacon frame that carries a trigger frame information element comprising sending information of a trigger frame for indicating a sending period of the trigger frame; and sends the beacon frame. In this case, the station switches to an active state, and receives the trigger frame by listening to the channel, and the station performs uplink transmission according to indication of the trigger frame after receiving the trigger frame. In this way, when signaling overheads are not increased and reliability is ensured, a station can learn of a sending time of a trigger frame, and the station remains in a receiving state in an appropriate period of time.

Methods, devices, systems, and means for selection of a coordinating user equipment, UE, in a user equipment-coordination set, UECS, that facilitates selection of the coordinating UE by the UEs in the UECS are described herein. Sharing of the role of coordinating UE by UEs in the UECS can be scheduled in a round-robin manner. Selection criteria can be used to determine which one or more UEs in the UECS will offer better performance in the role of coordinating UE.

A short cycle configuration method The method includes: for a plurality of discontinuous reception (DRX) groups of a user equipment, configuring, by a base station, a DRX short cycle parameter of the DRX group for a first frequency band and/or the DRX group for a second frequency band; where a frequency of the first frequency band is higher than a frequency of the second frequency band.

A method for multicast communication. The method which may be performed by a terminal device comprises receiving a downlink control channel from a network node. The downlink control channel may be associated with a traffic of the terminal device. The method further comprises determining an uplink resource to transmit feedback for the traffic to the network node, according to the association between the downlink control channel and the traffic. A hybrid automatic repeat request feedback may be implemented efficiently and flexibly for different traffic such as multicast and unicast traffic.

A signal processing method includes receiving, by a terminal, first indication information and second indication information. The first indication information indicates at least one first resource block group. The second indication information indicates a second resource block group. The second resource block group belongs to the at least one first resource block group. The signal processing method also includes receiving, by the terminal, a downlink signal on the at least one first resource block group. The signal processing method further includes processing the downlink signal based on the second indication information.

Various aspects of the disclosure relate to distributed multiple-input multiple-output (MIMO) communication such as coordinated beamforming or Joint MIMO. In some aspects, distributed MIMO is used to support communication in a cluster of wireless nodes (e.g., access points). A distributed MIMO scheduling scheme as taught herein is used to schedule the wireless nodes (e.g., access points and/or stations) operating within the cluster. For example, stations may be scheduled across basis services sets of the access points for a downlink transmission and/or an uplink transmission.

The present invention relates to a wireless communication terminal and a wireless communication method for efficiently managing simultaneous data transmissions of a plurality of terminals. To this end, provided are a base wireless communication terminal including: a transceiver configured to transmit and receive a wireless signal; and a processor configured to control an operation of the base wireless communication terminal, wherein the processor is configured to: transmit a trigger frame triggering a multi-user uplink transmission of a plurality of terminals, receive multi-user uplink data through resources allocated to the plurality of terminals, and transmit a block ACK through the resources in response to the received multi-user uplink data, wherein the transmission of the block ACK in each resource is terminated at the same time, and a wireless communication method using the same.
