Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
The signal that is used for positioning function can be carried by the MBSFN subframe, for the user terminal of deferring to LTE R8 agreement, generally can receive the control of the clean culture on preceding 1～2 OFDM symbol signaling in the MBSFN subframe, and can not handle any signal that sends on the OFDM symbol of back, therefore, the base station can utilize other OFDM symbols except 1～2 OFDM symbol to send location reference signals in the MBSFN subframe.When adopting the MBSFN subframe to carry framing signal, see also Fig. 1, it is a kind of schematic flow sheet that sends the method for location configuration information of one embodiment of the invention, this method may further comprise the steps.
Step 101: handle the MBSFN subframe configuration information, make the MBSFN subframe configuration information comprise the MBSFN subframe for positioning function;
Need to prove that carrying out the executive agent that sends the location configuration information in the embodiment of the invention can be the base station, can be the centre of location also, the present invention does not limit this, can be network element or network entity that any realization sends the location configuration information.
The configuration information of above-mentioned MBSFN subframe can be broadcast to user terminal in system broadcast information, for example, and broadcasting in SIB2 (System Information Block 2, system information block 2).The MBSFN subframe configuration information mainly comprises three parts composition: radio frames assignment period, radio frames allocation offsets and sub-frame allocation.
Wherein, the span of radio frames assignment period can be 1,2,4,8,16 and 32, and unit is radio frames.The span of radio frames allocation offsets is 0～7, and unit is radio frames.
Sub-frame allocation can have two kinds of forms, a kind of form is a radio frames, totally 6 bits, under FDD (Frequency Division Duplex, Frequency Division Duplexing (FDD)) situation, these 6 bits are subframe 1, subframe 2, subframe 3, subframe 6, subframe 7 and subframe 8 in corresponding the radio frames respectively, at TDD (TimeDivision Duplex, time division duplex) under the situation, subframe 3, subframe 4, subframe 7, subframe 8 and 9, the 6 bits of subframe need not in corresponding the radio frames respectively for preceding 5 bits;
Another form of sub-frame allocation is 4 continuous radio frames, totally 24 bits, under the FDD situation, per 6 bits are subframe 1, subframe 2, subframe 3, subframe 6, subframe 7 and subframe 8 in corresponding each radio frames respectively, under the TDD situation, per 5 bits are subframe 3, subframe 4, subframe 7, subframe 8 and the subframe 9 in corresponding each radio frames respectively, and last 4 bits need not.Utilize each bit value to indicate the type of the subframe corresponding with this bit respectively.For example, when the bit value of subframe 3 correspondences is 1, can represent that subframe 3 is the MBSFN subframe, when the bit value of subframe 3 correspondences is 0, can represent that subframe 3 is normal sub-frames, vice versa.
Step 102: set up indication information, described indication information is used in reference to the MBSFN subframe that is used for positioning function in the MBSFN subframe configuration information is shown;
Wherein, when a whole set of MBSFN subframe configuration information during all for positioning function, described indication information adopts the form of index or bitmap to generate, and wherein, index value or bitmap values are used in reference to the MBSFN subframe configuration information that is used for positioning function in the set of MBSFN subframe configuration information is shown.Because in the SIB2 of system broadcast information, the MBSFN configuration information has many covers, has constituted the set of MBSFN subframe configuration information.Processed MBSFN subframe can comprise the cover in the set of MBSFN subframe configuration information or overlap the MBSFN subframe configuration information more, simultaneously, when the MBSFN subframe configuration information a whole set of during all for positioning function, the indication information employing index that the MBSFN subframe configuration information comprises or the form generation of bitmap.
For example, if indication information generates with the index form, see also Fig. 2, it is the schematic diagram of indication information of a kind of index form of one embodiment of the invention.As shown in Figure 2, indicate the MBSFN subframe configuration information that in the set of MBSFN subframe configuration information, is used for positioning function by index value.For example, when first cover in the set of MBSFN subframe configuration information, the 3rd cover and n cover MBSFN subframe configuration information are used for positioning function, then comprise 3 index values in the indication information of corresponding index form with it, utilize index value itself to indicate first cover, the 3rd cover and n cover MBSFN subframe configuration information in the set of MBSFN subframe configuration information to be used for positioning function respectively.If MBSFN subframe configuration information the whole series all are used for positioning function, all the MBSFN subframes in the MBSFN subframe configuration information are the MBSFN subframe for positioning function.
In another embodiment of the present invention, if indication information generates with bitmap form, see also Fig. 3, it is the schematic diagram of indication information of a kind of bitmap form of another embodiment of the present invention.As shown in Figure 3, the MBSFN subframe configuration information in the set of each MBSFN subframe configuration information has a corresponding bitmap with it, is indicated the MBSFN subframe configuration information that is used for positioning function in the set of MBSFN subframe configuration information by bitmap values.For example, when bitmap values is 1, illustrate that the MBSFN subframe configuration information corresponding with this bitmap is the MBSFN subframe configuration information for positioning function, when bitmap values is 0, illustrate that the MBSFN subframe configuration information corresponding with this bitmap is not the MBSFN subframe configuration information for positioning function, vice versa.Equally, because MBSFN subframe configuration information the whole series all are used for positioning function, therefore, all the MBSFN subframes in the MBSFN subframe configuration information are the MBSFN subframe for positioning function.
Wherein, when a whole set of MBSFN subframe configuration information during not all for positioning function, described indication information adopts the form of nested index or nested bitmap to generate, wherein, the nested index value of one-level or the nested bitmap values of one-level are used in reference to the MBSFN subframe configuration information that is used for positioning function in the set of MBSFN subframe configuration information are shown, and the nested index value of secondary or the nested bitmap values of secondary are used in reference to the MBSFN subframe that is used for positioning function in a whole set of MBSFN subframe configuration information is shown.
