Description
Technical field
The present invention relates to wireless communication field, in particular to a kind of Notification Method and system of independent midamble configuration information.
Background technology
In TD-SCDMA system, have employed intelligent antenna technology, its core uses adaptive wave beam shaping (Beamforming) technology, radio signal can be led concrete direction, produce spatial orientation wave beam, make antenna main beam aim at subscriber signal arrival direction, secondary lobe or zero falls into aims at interference signal arrival direction, thus reaches the object reducing and disturb, improve MPS process and improve power system capacity.Generally, smart antenna is used in base station end, and the smart antenna of base station receiver may be used for by the channel estimating of the signal of up link the performance improving down link.
In HSPA+, can cancel with DPCH in celldch state, therefore there will be user not only without adjoint DPCH but also without periodic uplink transmissions transmission resources such as up semi-continuous schedulings, do not having stable periodic uplink signal can be used for carrying out effective channel estimating in this case, in order to descending wave beam forming can not be affected, introduce Sounding (burst) reference signal in agreement in celldch state, based on standalonemidamble sounding burst structure as shown in Figure 1:
Can find out, the data field of sounding signal is empty, does not need to take Walsh code channel, and the code channel under saving can be used for transmitting uplink data.
Meanwhile, the midamble that sounding uses is independent midamble.When each time slot user number K=8, the Midamble method of salary distribution of acquiescence as shown in Figure 2:
The midamble method of salary distribution of acquiescence gives the corresponding relation of code channel and midamble, user can obtain its midamble code word used by the code channel distributed, such as when spreading factor is 4, if midamble code word is 1,3,5,7 are allocated to user, remaining 2,4,6,8 are independent midamble code word, sounding signal can use these independent midamble to send, and the independent midamble that sounding uses can configure to terminal and NodeB by RNC in celldch state.
In MIMO transmission, NodeB needs according to two antenna upper signal channel conditions to judge whether to enable stream transmission, and the mode therefore adopting sounding and HS-SICH alternately to send on two antennas makes NodeB can all obtain the judgement of uplink channel estimation for stream transmission on two antennas.
In MU-MIMO (multiuser MIMO) transmission, multiple user sends multiple data flow simultaneously, thus utilizes MU-MIMO technology to realize SDMA, and from terminal point, UE only needs single antenna reception data flow.The use of MU-MIMO needs the judgement relying on space isolation, and when not having stable periodic uplink signal, the judgement of space isolation needs to be obtained by the up sounding channel estimating of user.
As can be seen here, the Main Function of sounding is in celldch state, when there is no stable periodic uplink signal, terminal use periodically can send up sounding signal, NodeB carries out channel estimating to promote descending Beamforming figuration accuracy or for the judgement of MIMO double fluid transmission or the isolation etc. for judging empty point user, to save code channel resource simultaneously by this periodic sounding.
