Position, to which user equipment can be in the corresponding time-domain resource position in the second base station and frequency domain resource location resolution to corresponding
Configure resource.
Certainly, first base station is by descending control signaling other than it directly can be issued to user equipment, can also will under
Row control signaling is sent to the second base station, and then issuing same downlink to same category of user equipment via the second base station controls
Signaling.Briefly, it is exactly to forward descending control signaling via the second base station.The effect finally realized exactly controls downlink
Transmitting signaling downwards are to user equipment.
After first base station issues same descending control signaling to same category of user equipment, which will also
Channel measurement request is sent to user equipment, or the channel measurement request, such first base station are sent via the second base station
The channel state information between user equipment and the second base station can be got in real time, to which first base station is just in real time to the
User under two base stations carries out category division, and specific dividing mode is in the above-described embodiments it is stated that just no longer superfluous herein
It states.
Further, which will also receive the upstream data request and/or mixed automatic retransfer that user equipment uploads
