A transmitting wireless device provides channel spatial reuse information to a receiving wireless device for the receiving wireless device to make a determination of how to contend the medium for spatial reuse transmission, when to transmit and what transmissions parameters to use for the transmission in the spatial reuse. A timer is designated to track the remaining time for inter-ESS and/or intra-ESS spatial reuse. The spatial reuse information may include fields indicative of color code identifying BSS, transmission power used, signal to noise ratio headroom available and so on. With the spatial reuse information, the wireless device can calculate the target transmit power for initiating spatial reuse transmission without interrupting the on-going transmission, perform EDCA in spatial reuse condition to assess the channel status for contending the medium over the on-going transmission(s), tracking the spatial reuse duration and initiate a new spatial reuse transmission over the on-going transmission without interruption.

Techniques of improving EDCA mechanism in spatial reuse

Methods, apparatus, and systems for coordinating joint transmissions among multiple access points are described. In one example aspect, a wireless communication method includes receiving, by a communication device, a first frame from a master access point or a first intermediate communication device. The first frame indicates a joint transmission to be performed by multiple access points. The first frame includes a scheduling information for a secondary access point to perform the joint transmission and an indicator directing the communication device to forward the scheduling information. The method also includes transmitting, by the communication device, a second frame to the secondary access point or a second intermediate communication device. The second frame includes the scheduling information for the secondary access point to perform the joint transmission.

Coordinating joint transmissions among multiple access points

A method and a device for transmitting or receiving scheduling information are described. In the method for transmitting scheduling information, information about a scheduling result of resources to be occupied by one or more User Equipment (UEs) is acquired; and scheduling information including a first type of scheduling information and a second type of scheduling information is transmitted to the one or more UEs according to the information about the scheduling result. The first type of scheduling information includes information for parsing the second type of scheduling information, and the scheduling information determines a resource scheduling condition of the user.

Method and device for transmitting or receiving scheduling information

A method of setup a protection mechanism for scheduled transmissions to multiple stations is introduced. Through transmitting a control frame addressing to multiple stations for immediate simultaneous responses, the transmitter would know the stations that are ready for receiving the scheduled data frames and schedule the packet for those stations. Combining the transmission of the control frame with the power saving mechanism would allow triggering a group of power saving stations to wake up at same for receiving the control frame and scheduled user data frames. A new mechanism of simultaneous group responses to the control frame with orthogonal identifier information for individual station is provided to uniquely identify the responding stations.
