Problems solved by technology

However, this may not always be possible (due to long distances and / or poor radio propagation conditions), may be complex and / or may require additional circuitry in the base station, thereby increasing size and cost
Also, upgrades are inflexible and cumbersome if, for example, a new base station is introduced

Embodiment Construction

[0050] The following description focuses on embodiments of the invention applicable to broadband wireless metropolitan area networks (WMANs) and, in particular, to Institute of Electrical Engineers (IEEE) 802.16 standard communication systems. However, it will be appreciated that the invention is not limited to this application but may be applicable to many other systems including eg WLAN or cellular communication systems such as IEEE 802.22 (WRAN), GSM or UMTS. The invention is applicable to both permissioned and permissionless systems.

[0051] figure 2 An example of a communication system according to some embodiments of the invention is illustrated.

[0052] In the system, first and second base stations 201, 203 support a number of remote stations, of which three remote stations 205, 207, 209 are shown. In particular, the base stations 201, 203 are WMAN base stations operating according to the IEEE 802.16 standard well known to those skilled in the art.

Abstract

A cellular communication system comprises a set of base stations (201,203) which transmit downlink resource exchange discovery messages to remote terminals in resource allocations of a Media Access Control, MAC, frame structure. The discovery messages may indicate that a base station has resource available for reallocation to another base station or that a base station is seeking resource to be allocated from another base station. A remote terminal (205) comprises a receiver (401, 403) which receives a first message of the downlink resource exchange discovery messages from at least a first base station (201). A discovery message transmit processor (407) generates a second message, which is an uplink resource exchange message comprising resource exchange data determined from the first message, and transmits this to a second base station (203). The second base station (203) then initiates a temporary air interface resource reallocation with the first base station in response to receiving the second message.

Description

technical field [0001] The present invention relates to resource exchange discovery in cellular communication systems, and in particular, but not exclusively, to resource exchange for IEEE 802.16 networks or IEEE 802.22 networks. Background technique [0002] Wireless communication systems have become common over the past few decades. For example, cellular communication systems such as mobile communication systems, broadband wireless metropolitan area networks (WMANs) and wireless local area networks (WLANs) have become popular as a means of providing efficient communication services to eg mobile communication units. However, the increasing popularity of wireless communication systems has led to a significant increase in the need for air interface resources, and the need for efficient and flexible utilization of available resources has become necessary for the further development of wireless systems. [0003] A proposed method for efficiently increasing the utilization of a...
