US 2013/0294309 A1 · SCHEDULING SCHEMES FOR USER EQUIPMENT POWER SAVING IN A COMMUNICATION NETWORK

Abstract

In a method of allocating wireless medium resources in a communication system, the communication system including a base station and a plurality of client stations sharing a channel bandwidth, a frequency sub-band of the channel bandwidth is selected for allocating wireless medium resources to a client station. Wireless medium resources are allocated at the base station to the client station. The base station is constrained to allocate wireless medium resources to the client station within the selected frequency sub-band. A subframe is generated for transmission to the client station. The subframe includes at least a data region that contains data for the client station. The data for the client station is confined to be within the selected frequency sub-band.

Dependent claims

A method of allocating wireless medium resources in a communication system, the communication system including a base station and a plurality of client stations sharing a channel bandwidth, the method comprising:

selecting, for allocating wireless medium resources to a client station, a frequency sub-band of the channel bandwidth;
allocating, at the base station, wireless medium resources to the client station, wherein the base station is constrained to allocate wireless medium resources to the client station within the selected frequency sub-band;
and
generating a subframe for transmission to the client station, wherein the subframe includes at least a data region, and wherein the data region contains data for the client station, the data for the client station confined to be within the selected frequency sub-band.

1 more element

A method of operating a client station in a communication system, the communication system including a base station and a plurality of client stations sharing a channel bandwidth, the method comprising:

receiving, at a client station, a subframe having a control region and a data region, wherein the data region contains data for the client station, wherein the data is constrained to be within a frequency sub-band of the channel bandwidth;
and
switching operation of the client station from a fully powered state to a partially powered state for reception and processing of at least the data region of the subframe, wherein in the partially powered state, power is supplied to circuitry needed to receive and process only the frequency sub-band that contains data for the client station.

A communication device configured to operate in a communication system, the communication system including a plurality of client stations sharing a channel bandwidth, the communication device comprising:

a network interface configured to
receive a subframe having a control region and a data region, wherein the data region contains data for the communication device, the data constrained to be within a frequency sub-band of the channel bandwidth, and
switch operation from a fully powered state to a partially powered state for reception and processing of at least the data region of the subframe, wherein in the partially powered state, power is supplied to circuitry needed to receive and process only the frequency sub-band that contains data for the communication device.
