40. The base station according to claim 36, wherein in the event that the combined bandwidth request does not include details of individual bandwidth requests, the processor reserves an aggregate amount of bandwidth for the subscriber stations, said transmitter informing the relay station of the aggregate amount of bandwidth.
Bandwidth request control message format A of a combined IBR
Head Type of the message, etc.
Amount of the Nth IBR The number of units, such as bytes, of
uplink bandwidth requested by the Nth
Other information of the Nth IBR It is optional. It could be the relevant
Connection ID of the Nth IBR Connection ID
Check sequence To check the received message, such as
To decrease the size of the control message of a combined IBR, the RS can use the message format shown in FIG. 10 (Format B). The details of this control message are listed in Table 2. When using this message format, the RS will use one of its existing (previously configured) CIDs, which is associated with all CIDs used by its SS, or MS, and RS. The BS will know that the bandwidth request enclosed with this CID is used for the SSs and any other RSs connected to the RS.
The aggregation of all IBR The total number of units, such as
Other information It is optional. It could be the relevant
Connection ID RS can apply an existing connection ID,
Defining a protocol for an RS to process the received bandwidth requests.
Minimizing the control message overhead by classifying and combining received bandwidth requests in RS.
Decreasing the collision probability for the contention style bandwidth request.
The method proposed can be used for other message relaying, thus achieving the above benefits.
Embodiments of the present invention may be implemented in hardware, or as software modules running on one or more processors, or on a combination thereof. That is, those skilled in the art will appreciate that a microprocessor or digital signal processor (DSP) may be used in practice to implement some or all of the functionality of the RS or BS in particular embodiments of the present invention. It is also possible to provide each SS with some or all of the functionality of the RS. Particular embodiments of the invention may also be embodied as one or more device or apparatus programs (e.g. computer programs and computer program products) for carrying out part or all of any of the methods described herein. Such programs embodying the present invention may be stored on computer-readable media, or could, for example, be in the form of one or more signals. Such signals may be data signals downloadable from an Internet website, or provided on a carrier signal, or in any other form.
