Abstract
Methods, apparatus, media and signals for assigning frequency channels to a beam in a multi-beam cellular communications system are disclosed. One method involves receiving an indication of channel quality representing a channel quality in the second region, of a frequency channel used in the first region to communicate with the source. The method further involves handing off the frequency channel to a transceiver in the second region to cause the transceiver in the second region to use the frequency channel to communicate with the source in the second region, in response to the indication representing at least a pre-determined minimum channel quality.
Claims9
A method of communicating with a source moving from a first region to a second region, the method comprising:
- receiving an indication of channel quality representing a channel quality in said second region, of a frequency channel used in said first region to communicate with said source;
- and
- handing off said frequency channel to a transceiver in said second region to cause said transceiver in said second region to use said frequency channel to communicate with said source in said second region, in response to said indication representing at least a pre-determined minimum channel quality.
A computer readable medium for providing codes for directing a processor in a multi-beam cellular communications system, to communicate with a source moving from a first region to a second region, by:
- a) receiving an indication of channel quality representing a channel quality in said second region, of a frequency channel used in said first region to communicate with said source;
- and
- b) handing off said frequency channel to a transceiver in said second region to cause said transceiver in said second region to use said frequency channel to communicate with said source in said second region, in response to said indication representing at least a pre-determined minimum channel quality.
A computer data signal embodied in a carrier wave, said data signal comprising code segments for directing a processor in a multi-beam cellular communications system, to communicate with a source moving from a first region to a second region, said code segments comprising:
- a) a first code segment for directing said processor to receive an indication of channel quality representing a channel quality in said second region, of a frequency channel used in said first region to communicate with said source;
- and
- b) a second code segment for directing said processor to hand-off said frequency channel to a transceiver in said second region to cause said transceiver in said second region to use said frequency channel to communicate with said source in said second region, in response to said indication representing at least a pre-determined minimum channel quality.
An apparatus for communicating with a source moving from a first region to a second region, the apparatus comprising:
- a) means for receiving an indication of channel quality representing a channel quality in said second region, of a frequency channel used in said first region to communicate with said source;
- and
- b) means for handing off said frequency channel to a transceiver in said second region to cause said transceiver in said second region to use said frequency channel to communicate with said source in said second region, in response to said indication representing at least a pre-determined minimum channel quality.
An apparatus for communicating with a source moving from a first region to a second region, the apparatus comprising:
- a) a receiver operable to receive an indication of channel quality representing a channel quality in said second region, of a frequency channel used in said first region to communicate with said source;
- and
- b) a frequency channel assignment device operable to hand-off said frequency channel to a transceiver in said second region to cause said transceiver in said second region to use said frequency channel to communicate with said source in said second region, in response to said indication representing at least a pre-determined minimum channel quality.
