Merge, certain uplink receiving diversity gain can be obtained by combining to receive, to promote the receptivity of edge customer.
When using CoMP, since Cell Center User signal quality is preferable, the space of performance boost is limited, using joint
It receives, to occupy the uplink time/frequency source of multiple cells instead, be unfavorable for the promotion of average spectral efficiency (ase).Therefore joined using CoMP
Splice grafting, which is received, only to be supported to being connect combining for uplink receiving data with neighboring community's edge customer progress in 3 sectors of station in cooperation range
It receives.The edge customer for participating in joint reception can be according to RSRP (the Reference Signal of the local area and adjacent area measured
Receiving Power, Reference Signal Received Power) difference (such as A3 event measurement reports) determines.Due to assisting cell
Acquisition be to be judged by position measurement, the position measurement of terminal is only capable of the channel strength of feeding back downlink, can not be effectively anti-
Answer the channel situation of uplink.If the interference of up channel is stronger, the CoMP of uplink can not obtain gain.

Mask body explanation.
If the interference bottom that base station obtains is made an uproar, lifting IOT values are less than the candidate participation uplink CoMP cell of predetermined threshold value
(the interference bottom of namely serving cell make an uproar lifting IOT values larger), then check whether serving cell can replace the positions PUSCH of UE
It sets and (mainly checks whether that the PUSCH that can replace UE is positioned adjacent to cell).If serving cell can replace UE's
The positions PUSCH (have the PUSCH that can replace UE to be positioned adjacent to cell), then return and continue the candidate participation uplink CoMP cell of comparison
IOT values and predetermined threshold value, reselect assistance cell；If the positions PUSCH that serving cell cannot replace UE (can not be more
The PUSCH for changing UE is positioned adjacent to cell), then exit Combined Treatment JR states.
If the interference bottom that base station obtains is made an uproar, lifting IOT values are less than the candidate participation uplink CoMP cell quantity of predetermined threshold value
More than or equal to 1, then interference bottom is selected to make an uproar the relatively small candidate uplink CoMP cell that participates in of lifting IOT values as assistance cell.
Configuration cooperation cell information enters Combined Treatment JR states.
In one embodiment of the invention, the method for determining the cooperation cells uplink coordinated multicast communication CoMP further includes pair
