Abstract: Techniques for adjusting a contention window (CW) for transmissions in a shared radio frequency spectrum band may include identifying a number of nodes attempting to transmit using a channel of a shared radio frequency spectrum band and determining a target CW based on the number of nodes attempting to transmit. A new CW value may then be determined based on a prior CW value and the target CW value, and a listen-before-talk (LBT) procedure (e.g., a clear channel assessment (CCA)) to access the channel of the shared radio frequency spectrum band may be performed to access the channel.

Abstract: A method for confirming receipt of an aggregated data frame containing one or more decoding errors is disclosed. A wireless device receives the aggregated data frame from another device over a wireless channel, determines a transmit duration of the aggregated data frame, and defers access to the channel for a time period selected as either an EIFS duration or a DIFS duration based, at least in part, on the transmit duration, and then transmits a block acknowledgement frame to the other device after the time period.

Abstract: Methods, systems, and devices are described for efficient use of transmit opportunities (TXOPs) through adjustment of contention window backoff time values to compensate for one or more TXOPs that may exceed a TXOP limit. A contention window value may be increased, for example, to provide other devices in the network with a fair opportunity for network access based at least in part on one or more TXOPs that exceed the TXOP limit. Allowing one or more transmissions to exceed a TXOP limit may provide enhanced efficiency as compared to having multiple transmissions.

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.
