Abstract: Aspects of the disclosure provide an apparatus for wireless communication. The apparatus includes a transceiver and a processing circuit. The transceiver is configured to transmit and receive wireless signals. The processing circuit is configured to detect an error of a previous scheduled transmission of data units from the apparatus to another apparatus. The other apparatus provides scheduled resources for transmission between the two apparatuses. Further, the processing circuit is configured to determine resources that are scheduled by the other apparatus for the apparatus to perform retransmission, and provide one or more of the data units in the previous scheduled transmission to the transceiver for retransmission using the scheduled resources.

Abstract: Aspects of the disclosure provide an apparatus for wireless communication. The apparatus includes a transceiver and a processing circuit. The transceiver is configured to transmit and receive wireless signals. The processing circuit is configured to determine a transmission parameter adjustment for the transceiver, detect that the transmission parameter adjustment has a potential to cause a collision to an overlapping basic service set (OBSS), adjust timings for transmission control to avoid the collision, and control the transceiver based on the determined transmission parameter adjustment and the adjusted timings for transmission control.

Abstract: A method is carried out on a device capable of utilizing a high efficiency wireless local area network (HEW) communication protocol and a legacy communication protocol, and includes wirelessly receiving a communication frame; when the measured energy level of the frame exceeds a static clear channel assessment (CCA) energy level, identifying the BSS to which the frame corresponds, wherein identifying the BSS to which the frame corresponds comprises utilizing a BSS identifier included in the frame when the frame is an HEW frame or utilizing a MAC address included in the frame when the frame is a legacy frame; when the frame corresponds to the same BSS as the device, processing the frame utilizing the static CCA energy level; and when the frame corresponds to an overlapping OBSS, processing the frame utilizing a dynamic CCA energy level.

Abstract: A method for changing a first basic service set (BSS) color identifier for a first communication device identifiable by the first BSS color identifier and a first basic service set identifier that is longer than the first BSS color identifier is described. An indication that the first BSS color identifier and a second BSS color identifier for a second communication device have a same first value is received by the first communication device. Respective service coverage areas of the first and second communication devices at least partially overlap. A second value of the first BSS color identifier is determined by the first communication device in response to the indication. A notification frame that indicates the second value and a start time are generated by the first communication device. The first BSS color identifier is changed by the first communication device to the second value based on the start time.

Abstract: A method for accessing a shared medium includes receiving, at a first device associated with a first basic service set (BSS), a packet from a second device associated with a second BSS. The packet includes an indication of a duration for which the shared medium is expected to be busy. The method includes setting, at the first device, a first counter for an inter-BSS channel access to the duration in response to the second BSS being different than the first BSS and in response to the duration being greater than a current value of the first counter. The method includes setting, at the first device, a second counter for an intra-BSS channel access to the duration in response to the second BSS being the same as the first BSS and irrespective of whether the duration indicated in the packet is greater than a current value of the second counter.

Abstract: The present disclosure includes systems and techniques relating to controlling access to a shared communication medium in a wireless communication system. In some implementations, a first communication device associated with a first basic service set (BSS) identified by a first BSS indicator receives a data unit transmitted by a second communication device. The data unit includes (i) a second BSS indicator indicating a second BSS associated with the second communication device and (ii) a duration indicator indicating a duration of time for which the shared communication medium is expected to be busy. An inter-BSS channel access counter is set based on the duration of time indicated by the duration indicator if the second BSS is different from the first BSS. An intra-BSS channel access counter is set based on the duration of time indicated by the duration indicator if the second BSS is the same as the first BSS.

Abstract: A first communication device maintains respective spatial reuse information for respective pairs of second communication devices, the respective spatial reuse information for determining whether the first communication device can simultaneously transmit during respective transmissions between the respective pairs of second communication devices. The first communication device determines whether the first communication device can transmit a spatial reuse transmission to a third communication device simultaneously with one or more ongoing transmissions between one or more pairs of second communication devices using the spatial reuse information. Responsive to determining that the first communication device can transmit the spatial reuse transmission, the first communication device transmits a packet to the third communication device simultaneously with the one or more ongoing transmissions between one or more pairs of second communication devices.

Abstract: In a method for determining whether a communication device can transmit via a first communication channel, the communication device receives a packet via a second communication channel and sets a network allocation vector (NAV) timer corresponding to the second communication channel using duration information included in the header of the packet. The communication device determines whether the second communication channel overlaps in frequency with a first communication channel. If the second communication channel overlaps the first communication channel, the communication device is not permitted to transmit via the first communication channel when the NAV timer is not zero. If the second communication channel does not overlap the first communication channel, the communication device is permitted to transmit via the second communication channel even when the NAV timer is not zero.
