Abstract: Provides are a method and an apparatus for transmitting a feedback frame in a wireless local area network (WLAN) system. Specifically, a station (STA) receives, from an access point (AP), a null data packet announcement (NDPA) frame indicating transmission of a null data packet (NDP). The STA receives the NDP from the AP. The STA transmits, to the AP, a feedback frame including channel state information determined based on the NDP. The channel state information indicates a feedback subcarrier in each subcarrier group. The subcarrier group is generated based on grouping information using subcarriers in a frequency band excluding a guard subcarrier and a DC subcarrier. The feedback subcarrier is included in a subcarrier with an odd-numbered subcarrier index. The feedback subcarrier corresponds to a subcarrier with an even-numbered subcarrier index that is adjacent to the subcarrier with the odd-numbered subcarrier when the subcarrier with the odd-numbered subcarrier is a null subcarrier.

Abstract: A communications device establishes a communications context for communicating data packets using a packet communications bearer from the communications device via a mobile communications network. A controller of the communications device is configured to identify that the communications device can enter a stasis state because no data packets are available for transmission for a predetermined time via the packet communications bearer or there are no data packets to receive via the packet communications bearer, to transmit a stasis state message to the mobile communications network, and to store information relating to the communications context associated with the packet communications bearer in a data store. The stored information can be used by the controller to re-establish the packet communications bearer to transmit and/or receive data packets using the packet communications bearer, the communications device thereby entering the stasis state.

The transmitter converts a sequence obtained by multiplexing multiple bits to be transmitted to a plurality of users to parallel signals, and broadly disperses the parallel signals in the time and frequency domains.
