Abstract
In a multicarrier communication network, specific subcarriers are dedicated for use in carrying burst descriptor information. A subscriber station in the network may monitor the dedicated subcarriers to determine when a burst involving the station is to occur. By using dedicated subcarriers for burst information, scheduling decisions can be made closer in time to the actual bursts.
Claims28
A machine implemented method comprising:
- monitoring, at a first wireless subscriber station, a subset of subcarriers within a series of multicarrier symbols for burst descriptors, said subset of subcarriers being dedicated for transmission by a remote base station of burst descriptor information, wherein said series of multicarrier symbols are allocated to carry data communication between said remote base station and a plurality of wireless subscriber stations and said subset of subcarriers that are dedicated for transmission of burst descriptor information extends across said series of multicarrier symbols in time, wherein no other information is permitted to be transmitted within said subset of subcarriers but burst descriptor information;
- and
- when a burst descriptor is detected that is directed to said first wireless subscriber station:
- reading said burst descriptor to determine a type of burst that is scheduled to occur and a time said burst is scheduled to occur;
- and
- preparing said first wireless subscriber station to process said burst.
3 more elements
An apparatus comprising:
- a multicarrier transceiver to support wireless communication between said apparatus and a remote wireless base station within a series of multicarrier symbols;
- and
- a burst descriptor monitor to monitor predetermined subcarriers within said series of multicarrier symbols to detect burst descriptors carried by said predetermined subcarriers that are directed to said apparatus, said burst descriptors having been transmitted by said remote wireless base station and each burst descriptor to describe a burst that is to occur shortly after detection of said burst descriptor, wherein said predetermined subcarriers are dedicated for use by said remote wireless base station to transmit burst descriptors and extend across said series of multicarrier symbols in time, wherein no other information is permitted to be transmitted within said predetermined subcarriers but burst descriptors.
An apparatus for use in a multicarrier base station, comprising:
- a multicarrier transceiver to support wireless communication between said multicarrier base station and one or more remote subscriber stations within a coverage region of said multicarrier base station in a series of multicarrier symbols;
- and
- a scheduler to schedule multicarrier communications between said multicarrier base station and said one or more remote subscriber stations within said series of multicarrier symbols, said scheduler to deliver burst descriptors to said multicarrier transceiver to be transmitted, using dedicated subcarriers, to corresponding remote subscriber stations, said burst descriptors to each describe a corresponding burst that is scheduled to occur a short time after transmission of said burst descriptor, wherein said dedicated subcarriers that are dedicated for transmission of burst descriptors extend across said series of multicarrier symbols in time, wherein no other information is permitted to be transmitted within said dedicated subcarriers but burst descriptors.
A system comprising:
- at least one dipole antenna;
- a multicarrier transceiver, coupled to said at least one dipole antenna, to support wireless communication between said apparatus and a remote wireless base station within a series of multicarrier symbols;
- and
- a burst descriptor monitor to monitor predetermined subcarriers within said series of multicarrier symbols to detect burst descriptors carried by said predetermined subcarriers that are directed to said system, said burst descriptors having been transmitted by said remote wireless base station and each burst descriptor to describe a burst that is to occur shortly after detection of said burst descriptor, wherein said subset of subcarriers is dedicated for use by said remote wireless base station to transmit burst descriptors and extends across said series of multicarrier symbols in time, wherein no other information is permitted to be transmitted within said predetermined subcarriers but burst descriptors.

An article comprising a computer readable storage medium having instructions stored thereon that, when executed by a computing platform, operate to:
- monitor, at a first wireless subscriber station, a subset of subcarriers within a series of multicarrier symbols for burst descriptors, said subset of subcarriers being dedicated for transmission by a remote base station of burst descriptor information, wherein said series of multicarrier symbols are allocated to carry data communication between said remote base station and a plurality of wireless subscriber stations and said subset of subcarriers that are dedicated for transmission of burst descriptor information extends across said series of multicarrier symbols in time, wherein no other information is permitted to be transmitted within said subset of subcarriers but burst descriptor information;
- and
- when a burst descriptor is detected that is directed to said first wireless subscriber station:
- read said burst descriptor to determine a type of burst that is scheduled to occur and a time said burst is scheduled to occur;
- and
- prepare said first wireless subscriber station to process said burst.
