Flexibly disabling particular uplink or downlink channels when in a state of power imbalance
摘要
說明書
In area B in a heterogeneous network and a similar environment, because quality of an uplink channel from the UE to the first base station is better than quality of an uplink channel from the UE to another base station (for example, a macro base station), it is more probable that the first base station correctly receives the E-DCH data sent by the UE. Therefore, the first base station may be used to receive new E-DCH data sent by the UE and then send the new E-DCH data in an uplink direction to an RNC. By using the technical solution in the present disclosure, more E-HICHs feed back an ACK to the UE. This reduces a case in which all E-HICHs of the UE feed back an NACK, reduces a quantity of times that the UE retransmits E-DCH, and improves E-DCH transmission efficiency.
When the first E-HICH indicates a NACK, the UE retransmits E-DCH data.
That the first base station is located within a detection range of the UE includes that downlink pilot quality that is of the first base station and measured by the UE is greater than a preset first threshold value. The first threshold value refers to a minimum value of pilot quality at which the UE correctly decodes the E-HICH sent by the first base station.
Further, before the UE receives the first E-HICH sent by the first base station, the method may further include the following.
