Description
Technical field
The present invention relates to communication technical field, relate in particular to the transmission method of descending control signaling in a kind of TDS-CDMA evolution system.
Background technology
TD SDMA (TD-SCDMA, Time Division-Synchronous Code DivisionMultiple Access) technology is the technical standard of unique employing time division duplex (TDD, Time Division Duplex) mode in the three big international standards of 3-G (Generation Three mobile communication system).TD-SCDMA supports the transmission of up-downgoing non-symmetrical service, has bigger flexibility on spectrum utilization.TD-SCDMA system synthesis has adopted the advanced technology in the radio communications such as smart antenna, uplink synchronous, joint-detection and software radio, makes system have the higher performance and the availability of frequency spectrum.
Along with the development and the development of technology of society, people improve constantly the demand of mobile communication, objectively require mobile communication system that the data transport service of bigger capacity, higher rate, lower time delay can be provided.In order to satisfy this growing demand, 3G (Third Generation) Moblie collaborative project group (3GPP, 3
RdGeneration Partnership Project) TD-SCDMA evolution system scheme has been proposed.
In TD-SCDMA evolution system scheme, determine that at present down channel adopts OFDM (OFDM, Orthogonal Frequency Division Multiplex) technology.OFDM technical support 1.25MHz, 1.6MHz, 2.5MHz, 5MHz, 10MHz and 20MHz system bandwidth, frame structure can adopt the frame structure with the TD-SCDMA system compatible, as shown in Figure 1, the radio frames of a 10ms is made of the field of two 5ms, each field is by seven common time slot (TS, Time Slot) and three special time slots constitute, common time slot be numbered TS0 to TS6.Wherein, common time slot is used for control channel and business datum, and three special time slots are respectively: descending pilot frequency time slot (DwPTS, Downlink PilotTime Slot) is used for the down-going synchronous information of transmitting system; Uplink pilot time slot (UpPTS, Uplink Pilot Time Slot) is used to send the uplink synchronous information that the user inserts; (GP GuardPeriod), is used to provide the time interval of descending sending time slots to up sending time slots conversion to the translation and protection time slot.
The Transmission Time Interval of TD-SCDMA evolution system (TTI, Transmission Time Interval) length is defined as the length of a common time slot, i.e. 0.675ms.TTI is also referred to as a subframe of TD-SCDMA evolution system, and in the TD-SCDMA evolution system, subframe is identical with the notion of time slot.Wherein, a common time slot is made of 9 OFDM symbols or 8 OFDM symbols, corresponds respectively to Cyclic Prefix (CP, the Cyclic Prefix) configuration of different length: when adopting the short common CP of length, a common time slot is made of 9 OFDM symbols; When adopting the long expansion CP of length, a common time slot is made of 8 OFDM symbols.
And in Wideband Code Division Multiple Access (WCDMA) (WCDMA, the Wideband Code Division Multiple Access) evolution scheme, the frame structure of system as shown in Figure 2, the radio frames of a 10ms is made of 20 isometric wireless time slots, time slot be numbered 0 to 19.The length of each time slot is 0.5ms, and per two time slots constitute a subframe, i.e. the TTI of WCDMA evolution system, and the length of subframe is 1ms.One of them time slot is made of 7 OFDM symbols or 6 OFDM symbols, corresponds respectively to the CP configuration of different length: when adopting the short common CP of length, a time slot is made of 7 OFDM symbols; When adopting the long expansion CP of length, a time slot is made of 6 OFDM symbols.
In WCDMA evolution system and TD-SCDMA evolution system, descending control signaling can be divided into descending shared control signaling and downlink dedicated control signaling.Descending shared control signaling is to be sent by the base station, can be received by terminals all in the sub-district (UE, User Equipment); Downlink dedicated control signaling also is to be sent by the base station, and it receives liking specific certain UE or one group of UE.Descending shared control signaling is used for the defeated mode of multi-antenna transmitting that transmission system is business data transmission resource of distributing and business datum, for example, system can distribution service The data multiple-input and multiple-output (MIMO, Multi-InputMulti-Output) mode or send diversity mode and send, also can distribution service The data single antenna mode or intelligent antenna beam excipient mode send.Downlink dedicated control signaling is used to indicate code rate, the digital modulation that certain UE or one group of UE service data transmission adopted and mixes automatic repeat requests information such as (HARQ, Hybrid Auto Repeat Request).
At present, for the WCDMA evolution system, determined substantially that descending control signaling transmits in the individual OFDM symbol of the preceding m (m≤3) of a TTI.The benefit of this mode is that UE can receive descending control signaling soon, obtains the transmission resource location of the business datum of self, thereby can receive business datum apace.If UE learns the data that do not send to this UE in this TTI after receiving descending shared control signaling, can also select not receive other data in this TTI, thereby save the battery expense of UE.
During the standard of TD-SCDMA evolution system was in and studies and defines, the transmission means of descending control signaling did not still have concrete technical scheme.At present, tend to the TD-SCDMA evolution system and adopt the descending control signaling transmission policy identical with the WCDMA evolution system.Because the TD-SCDMA evolution system is different with the frame structure of WCDMA evolution system,, then can cause the following problem if the TD-SCDMA evolution system adopts the descending control signaling transmission policy identical with the WCDMA evolution system:
(1) the descending control signaling expense is bigger: for the WCDMA evolution system, the individual OFDM symbol of m (m≤3) carries out the transmission of descending control signaling before using among the TTI, set m and equal 3, when a TTI comprised 14 OFDM symbols at most, descending control signaling expense proportion was 21% among the TTI; For the TD-SCDMA evolution system, if also adopt identical strategy to carry out the descending control signaling transmission, equal 3 when setting m, when a TTI comprises 9 OFDM symbols at most, descending control signaling expense proportion will be 33.3% among the TTI, with respect to the WCDMA evolution system, the descending control signaling expense is excessive.
(2) the common reference symbol expense is excessive: the descending shared control signaling of demodulation needs demodulation to comprise the common reference symbol of pilot frequency information, if in each TTI, all send descending shared control signaling, so, just correspondingly need in each TTI, all send common reference symbol.And for the TD-SCDMA evolution system, only need send descending shared control signaling in the descending time slot in a radio half frame, just can satisfy the channel condition information Testing requirement that its dispatching office needs, thereby common reference symbol also only need send in the descending time slot in a radio half frame.If the evolution system of TD-SCDMA adopts the control signaling transmission policy identical with the WCDMA evolution system, all send descending shared control signaling and common reference symbol at each TTI, then can cause the common reference symbol expense excessive.
(3) influence the use of closed loop multi-antenna transmitting transferring technologies such as wave beam forming: for the TD-SCDMA evolution system, the multi-antenna transmitting transferring technology of closed loops such as use wave beam forming need use the dedicated reference symbol, if in a TTI, have common reference symbol and dedicated reference symbol simultaneously, can cause whole reference symbol expense excessive, if do not use the quantity of dedicated reference symbol or minimizing dedicated reference symbol, can influence the performance of closed loop multi-antenna transmitting transferring technologies such as wave beam forming again.
Therefore, the descending control signaling transmission policy of WCDMA evolution system can't effectively be applied to still do not have the transmission method of descending control signaling in the effective TD-SCDMA evolution system in the prior art in the TD-SCDMA evolution system.
