Abstract

Embodiments disclosed herein address the need in the art for efficient management of grant, acknowledgement, and rate control channels. In one aspect, a list associated with a first station is generated or stored, the list comprising zero or more identifiers, each identifier identifying one of a plurality of second stations for sending a message to the first station. In another aspect, sets of lists for one or more first stations are generated or stored. In yet another aspect, the messages may be acknowledgements, rate control commands, or grants. In yet another aspect, messages comprising one or more identifiers in the list are generated. Various other aspects are also presented. These aspects have the benefit of reduced overhead while managing grant, acknowledgment and rate control messaging for one or more remote stations.

Claims

1. An apparatus, comprising:

a processor for generating a list comprising zero or more identifiers, the list associated with a first station, each identifier identifying one of a plurality of second stations for sending a first message to the first station; and

a transmitter for transmitting a second message to the first station, wherein the processor further generates the second message comprising zero or more of the identifiers from the list,

wherein the second message directs the first station to remove an identifier from a list of identifiers stored in the first station.

2. The apparatus of claim 1, wherein the list is generated in accordance with one or more predetermined criteria.

3. The apparatus of claim 1, further comprising a receiver for receiving a measurement of a second station, wherein the processor includes an identifier associated with the second station in the list in accordance with the received measurement and in accordance with one or more predetermined criteria.

4. The apparatus of claim 1, wherein the second message identifies a list of identifiers for storing in the first station.

5. An apparatus, comprising:

a processor for generating a list comprising zero or more identifiers, the list associated with a first station, each identifier identifying one of a plurality of second stations for sending a first message to the first station;

a transmitter for transmitting a second message to the first station, wherein the processor further generates the second message comprising zero or more of the identifiers from the list, wherein the second message directs the first station to add an identifier to a list of identifiers stored in the first station.

6. A method for monitoring messages, comprising:

generating a list comprising zero or more identifiers, the list associated with a first station, each identifier identifying one of a plurality of second stations for sending a first message to the first station; and

transmitting a second message to the first station, the second message comprising zero or more of the identifiers from the list,

wherein the second message directs the first station to remove an identifier from a list of identifiers stored in the first station.

7. The method of claim 6, further comprising storing the list of identifiers from the second message in the first station.

8. A method for monitoring messages, comprising:

generating a list comprising zero or more identifiers, the list associated with a first station, each identifier identifying one of a plurality of second stations for sending a first message to the first station; and

transmitting a second message to the first station, the second message comprising zero or more of the identifiers from the list, wherein the second message directs the first station to add an identifier to a list of identifiers stored in the first station.
