Embodiment
Embodiment one, and according to stipulating in the 3GPP agreement that network side is optional for transmit diversity, UE is to force to support for transmit diversity, therefore, do not have the support situation of cell indication UE for transmit diversity in the agreement.But in real network, not all UE realizes the support to transmit diversity according to agreement, for the scheduling that realizes that better network side sends data, proposes the method that a kind of data of present embodiment are sent, and referring to Fig. 1, this method can comprise:
101, the message that reports according to receiving terminal judges whether receiving terminal supports transmit diversity.
Receiving terminal comprises portable terminal, multimedia terminal, fixed telephone terminal etc.; Whether receiving terminal reports supports transmit diversity; New information can be set be used to indicate receiving terminal whether to support transmit diversity, also can in existing message, increase field and be used to indicate receiving terminal whether to support transmit diversity.
According to the message that receiving terminal reports, judge that whether this receiving terminal supports transmit diversity, can judge in the following manner:
Be used to indicate receiving terminal whether to support transmit diversity if new information is set, then receive this new information and just judge that receiving terminal do not support transmit diversity, do not receive this new information and just judge that receiving terminal supports transmit diversity; Perhaps,, judge that then receiving terminal supports transmit diversity,, judge that then receiving terminal do not support transmit diversity if this new information is FALSE if this new information is TRUE.In like manner, also can in existing message, be used to indicate receiving terminal whether to support transmit diversity by extended field.
102, when receiving terminal is not supported transmit diversity, select the antenna transmission data.
Can select transmitting antenna arbitrarily, also can select transmitting antenna in order, promptly each antenna sends data in turn, for example according to each antenna corresponding identification sign indicating number, selects the antenna transmission data successively; Also can be according to the load selection transmitting antenna; Can also adopt each antenna to send in turn and the mode that combines according to the load selection antenna transmission, the transmission of the data of transmit diversity receiving terminal is not supported in realization.
Wherein, Each antenna sends the mode of data in turn, can for, when supposing to have many antennas such as first antenna, second antenna, third antenna, the 4th antenna; First packet that needs to send is used first antenna transmission; Second packet that needs to send used second antenna transmission, and the 3rd packet that needs to send sends with third antenna, and the 4th packet that needs to send is with the 4th antenna transmission; The 5th packet that need to send with first antenna transmission,,, and the like, realize that each antenna sends data in turn.
Mode according to load selection antenna transmission data; Can select the minimum antenna transmission data of load, the threshold value of load also can be set, the antenna of selecting load to be lower than threshold value sends data in turn; Perhaps, select load to be lower than arbitrary transmission data in the antenna of threshold value.Can for, when supposing to have many antennas such as first antenna, second antenna, third antenna, the 4th antenna,, then adopt the first antenna transmission data if the minimum antenna of load is first antenna; Perhaps, the threshold value of load is set in advance, in the process that data are sent; Detect the load of each antenna, compare the load and the threshold value of each antenna, the antenna of selecting load to be lower than threshold value takes turns or arbitrary transmission data; For example, when supposing to have many antennas such as first antenna, second antenna, third antenna, the 4th antenna, be first antenna, second antenna and third antenna if load is lower than the antenna of threshold value; First packet that then need send is used first antenna transmission, and second packet that needs to send used second antenna transmission, and the 3rd packet that needs to send sends with third antenna; The 4th packet that needs to send used first antenna transmission; The 5th packet that needs to send used second antenna transmission ..., and the like, the antenna that the realization load is lower than threshold value sends data in turn; Perhaps, optional antenna second antenna transmission data from first antenna, second antenna and third antenna.
In addition; Also can adopt each antenna to send in turn and the mode that combines according to the load selection antenna transmission, detect the load of each antenna, when the load balancing of each antenna; Each antenna sends data in turn; When the load of antenna changes, when the load of each antenna is unbalanced, select the minimum antenna transmission data of load; The threshold value of load perhaps also can be set, and the antenna of selecting load to be lower than threshold value sends data in turn, perhaps, selects load to be lower than arbitrary transmission data in the antenna of threshold value.
Data are given receiving terminal through antenna transmission, and these data can comprise business datum, channel data, pilot data etc.
After receiving terminal receives data, adopt the corresponding pilot channel of transmitting antenna as the phase reference of separating timing.At present; R7 agreement regulation; The pilot channel that transmitting antenna is corresponding is P-CPICH and S-CPICH, is the situation of two transmit antennas, and the method that the present embodiment data are sent goes for the situation of two transmit antennas and two above transmitting antennas; When transmitting antenna is two, can adopt the pilot channel of agreement regulation; The number that needs spread pilot channel is the number of transmitting antenna when above when transmitting antenna is two, and transmitting antenna is corresponding one by one with pilot channel.
After UE receives data,, then adopt first pilot channel as the phase reference of separating timing if receive data from first antenna; If receive data, then adopt second pilot channel as the phase reference of separating timing from second antenna; If receive data, then adopt the 3rd pilot channel as the phase reference of separating timing from third antenna; If receive data, then adopt the 4th pilot channel as the phase reference of separating timing from the 4th antenna; If receive data, then adopt the 5th pilot channel as the phase reference of separating timing from the 5th antenna.
Further, the method that the present embodiment data are sent can also comprise: during the data re-transmission of each receiving terminal, adopt former transmitting antenna to send the data that retransmit.Change transmitting antenna if retransmit, need be with the information notice receiving terminal of new antenna, receiving terminal could receive data on new antenna; And may there be time delay in the process of notice; Some possibly can't be used the strict business of delay requirement, therefore, do not change transmitting antenna during re-transmission; Can reduce the time delay that data are sent, improve the efficient that data are sent.
