Abstract: Certain aspects of the present disclosure provide techniques and apparatus for starting an extended idle interval in an effort to avoid collisions with transmissions from hidden wireless nodes. One example apparatus generally includes a receiver and a processing system. The receiver is typically configured to receive a multi-user (MU) transmission comprising at least one packet for the apparatus. The processing system is typically configured to determine a checksum of the at least one packet and to start an idle interval associated with the apparatus after receiving the MU transmission if the at least one packet comprises a frame check sequence (FCS) that corresponds to the checksum, wherein the idle interval includes at least enough time for transmission of an acknowledgment (ACK) frame. For certain aspects, the idle interval may comprise an extended interframe space (EIFS).

Abstract: Systems and methods for low overhead paging in a wireless communications network are described herein. In some aspects, an apparatus for wireless communication includes a receiver and a processor. The receiver receives a request from a first device. The request indicates a first period of a plurality of periods corresponding to a periodicity for transmitting paging messages. The processor assigns the first device to a group scheduled to receive paging messages at most every first period based on the request and determines a start time for transmitting paging messages to the first device based on schedules for transmitting paging messages to a plurality of other devices. In other aspects, an apparatus for wireless communication includes a processor and memory. The processor derives an information sub-unit from an information unit associated with a paging message, compresses the information sub-unit, and generates a second information unit associated with the method of compression.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communication, including coordinated time domain multiple access (C-TDMA) among access points (APs) with different channels. In one aspect, while using C-TDMA, a first AP may receive a control message with scheduling information for a transmission opportunity (TXOP) from a second AP, which is the TXOP owner. The second AP may operate in a certain bandwidth, and first AP may operate in an overlapping portion of the same bandwidth, and also a different portion of bandwidth. The scheduling information may indicate a portion of the TXOP for the first AP to use during the TXOP. During the portion of the TXOP for the first AP, the first AP may perform a clear channel assessment (CCA) for the overlapping and non-overlapping portions, and transmit on both the overlapping and different bandwidths during the TXOP.

Abstract: This disclosure provides methods, devices and systems for synchronizing an end of an exchange of frames during a transmission opportunity (TXOP) with a target synchronization time using a synchronization short inter-frame space (SynSIFS) before a transmission by a wireless communication device that controls the medium. The wireless communication device obtains control of the medium for the TXOP by completing a CCA procedure. An exchange of frames during the TXOP includes transmissions from the wireless communication device and responses from other devices while the wireless communication device controls the medium. A duration of the SynSIFS may be adjustable at a microsecond granularity. Accordingly, the wireless communication device may select a duration of the SynSIFS that allows alignment of the end of the exchange with the target synchronization time. The wireless communication device also may adjust a number of symbols in the transmission from the wireless communication device.
