摘要:
A method for reduced overhead paging by an access point is described. The method includes assigning at least one paging identifier to at least one station. The method also includes partitioning a paging identifier space into paging identifier sets. The method further includes generating a paging message based on at least one of the paging identifier sets and the at least one paging identifier. The method additionally includes sending the paging message.

Simultaneous, multi-user uplink communication is scheduled in a wireless network by transmitting a poll message to a plurality of access terminals in response to receiving a first request to transmit data via uplink. The poll message includes a solicitation for requests to transmit data from each of the plurality of access terminals. The poll message also includes a medium reservation and schedule for transmission of the requests from the access terminals. Based on the requests received from the access terminals, a number of the access terminals are selected for simultaneous transmission of data via uplink. A transmit start message is sent to each of the selected access terminals indicating when and for how long the selected access terminals may transmit data via uplink. After the data is received, a block ACK message is sent to each of the selected access terminals indicating successful simultaneous communication.

Systems, methods, and devices for communicating a compressed beacon are described herein. In some aspects, a method of communicating in a wireless network. includes generating a compressed beacon. The compressed beacon includes a next full beacon time indication (NFBTI). The method further includes transmitting, at an access point, the compressed beacon.
摘要:
Systems, methods, and devices for communicating a compressed beacon are described herein. In some aspects, a method of communicating in a wireless network includes transmitting, at an access point, a full beacon at a first multiple of a beacon interval. The method further includes transmitting a compressed beacon at each beacon interval that is not the first multiple of the beacon interval. Another method of communicating in a wireless network includes receiving, at a wireless device, a full beacon at a first multiple of a beacon interval. The method further includes receiving a compressed beacon at a beacon interval that is not the first multiple of the beacon interval.
摘要:
Certain aspects of the present disclosure provide techniques and apparatus for signaling the bandwidth to be used for wireless communications using an RTS/CTS (Request to Send/Clear to Send) frame exchange, providing for bandwidths of at least 20 MHz, 40 MHz, 80 MHz, 160 MHz, or higher. This exchange of bandwidth information may be performed implicitly—by determining the channels in which the RTS/CTS frames are actually sent—or explicitly. In addition to this bandwidth information exchange, aspects of the present disclosure may also allow for Network Allocation Vector (NAV) protection in multiple channels. In this manner, the wireless medium may be reserved, and the transmission may be protected from hidden nodes.
摘要:
Certain aspects of the present disclosure provide techniques for signaling extended sizes for Medium Access Control (MAC) Protocol Data Unit (MPDU), Aggregated MPDU (A-MPDU) and Aggregated MAC Service Data Unit (A-MSDU) frame formats. A first technique proposes modifications to the current specifications of the IEEE 802.11n standard in order to allow for longer MPDUs in an A-MPDU. This technique reuses the IEEE 802.11n signaling format and utilizes reserved bits to convey the new information. The second technique proposes a new signaling mechanism to convey the extended sizes for the MPDU, A-MPDU and the A-MSDU through a very high throughput (VHT) capability element.

Certain aspects of the present disclosure provide a protocol to allow for load balancing between multiple frequency channels in a wireless communications system.
摘要:
Techniques for supporting communication over an extended range in a wireless network are disclosed. In one aspect, a station sends multiple messages of a given type for different operating modes. These messages can be detected by stations with different capabilities, which may avoid collisions between stations. In one design, a first station receives a Request-to-Send (RTS) message from a second station having data to send. The first station sends a first Clear-to-Send (CTS) message and also a second CTS message in response to the RTS message. The second CTS message has an extended range as compared to the first CTS message. The first station thereafter (i) receives data sent by the second station in response to the second CTS message and (ii) sends an acknowledgement having an extended range.
