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: Methods, systems, and devices are described for wireless communication. A transmitting device may transmit soliciting frames to a receiving device on a forward link. In response to the soliciting frames, the receiving device may transmit solicited frames in an immediate response back to the transmitting device on a reverse link. A solicited frame may fail to successfully decode at the transmitting device. The transmitting device in response may indicate an instantaneous value for one or more reverse link transmission parameters when sending a subsequent soliciting frame. The reverse link transmission parameters may be predetermined in a fixed mapping such that one or more values for the reverse link transmission parameters depend on values for the forward link transmission parameters. The receiving device may override the predetermined value and instead use the instantaneous value. An indicator of the instantaneous value may also be sent in a control field.
