Flexibly disabling particular uplink or downlink channels when in a state of power imbalance
摘要
說(shuō)明書(shū)
The scrambling code is a series of pseudo random code; on an uplink, a base station distinguishes and identifies users by identifying the scrambling code. The channelization code of the first E-HICH indicates which code channel is used by the first E-HICH sent to the UE. The signature sequence of the first E-HICH indicates a signature sequence used by the UE.
Further, the second instruction signaling includes timing information of the first E-HICH, where the timing information of the first E-HICH is used to indicate a start time location for sending each subframe of the first E-HICH.
The timing information of the first E-HICH is a timing offset τF-DPCH,n and/or a symbol location of a fractional downlink physical channel F-DPCH of the first base station. For example, a reference channel is a P-CCPCH, and a timing offset is τF-DPCH,n, which indicates that each F-DPCH frame/subframe is τF-DPCH,n later than the P-CCPCH. Channel timing of the first E-HICH may be known by using the timing offset τF-DPCH,n of the F-DPCH.
In another implementable manner, further, the second instruction signaling further includes a code channel and a signature sequence of an E-RGCH, where the E-RGCH is used to control E-DCH transmit power of the UE; or a code channel and a signature sequence of an E-RGCH, and timing information of the E-RGCH, where the timing information of the E-RGCH is used to indicate a time when the UE receives the E-RGCH, and the timing information of the E-RGCH is a timing offset τF-DPCH,n and/or a symbol location of a fractional downlink physical channel F-DPCH of the first base station.
