Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
Embodiment 1
The transmission of the embodiment of the invention 1 triggers the method for SRS configuration information can be according to the relative position of PDCCH trigger message in a SRS period of sub-frame, mode that can implicit expression transmit some former should be on PDCCH information transmitted.Referring to Fig. 2 (A), this method may further comprise the steps:
Step 101:, determine the pairing implicit information of first configuration information by first configuration information that presets and the corresponding relation of implicit information;
In the present embodiment, the base station has set in advance the corresponding relation of SRS period of sub-frame N, implicit information and subframe numbers and the corresponding relation of first configuration information and described implicit information.Preferably, the number of bits of implicit information has been determined by the SRS period of sub-frame in the base station, and the bit number of implicit information correspondence can pass through
Figure BSA00000164369700031
Calculate.For example, the SRS period of sub-frame is 4, by calculating The bit number that obtains the implicit information correspondence is 2, and the wherein represented configuration information of each bit has been determined in the base station, that is, first configuration information in the SRS configuration information, its corresponding implicit information have been determined to trigger in the base station.
For example, SRS can trigger by PDCCH, and PDCCH trigger message (being whole configuration informations) can be to the information below the UE transmission:
Whether-the UE that receives the PDCCH trigger message is triggered.
If-being triggered, how many shared bandwidth of the SRS of transmission is.
If-be triggered the position of the SRS of transmission on frequency domain.
If-being triggered, which (0 or 1) the shared broach of the SRS of transmission is.
If-being triggered, which the shared cyclic shift of the SRS of transmission is.
If-be triggered, send still SRS repeatedly of SRS.
If-send repeatedly, send how many times on earth.
-if repeatedly, so whether the frequency hopping of SRS is arranged, if what kind of frequency hopping mode is frequency hopping specifically adopt.
-some other information that needs indication.
More than the available some bits of each bar represent.Attention has various ways by the realization of PDCCH trigger message, the base station can want the UE that triggers to send a PDCCH trigger message at each, can want also that the UE that triggers is common to send a PDCCH trigger message at one group, the information of a plurality of UE is dealt in the same PDCCH trigger message.
Receive the UE of PDCCH trigger message,, learn whether oneself is triggered,,, carry out the transmission of SRS according to the configuration of indication if be triggered according to the information of carrying above.
In the prior art, to be used to trigger that trigger message that the configuration information of the SRS of UE all sends by physical layer control channel sends, thus, a lot of bits have been taken, and the method for the transmission of present embodiment triggering SRS configuration information together sends by implicit information and trigger message, promptly, the configuration information that a part triggers SRS sends by implicit information, the configuration information that another part triggers SRS sends by trigger message, and carry by the relative position that triggers the PDCCH place during transmission of implicit information, thereby reduce the shared number of bits of each physical layer control channel trigger message.
Accept example, above-mentioned PDCCH trigger message can be represented with X bit, for example first bit is represented " whether the UE that receives the PDCCH trigger message is triggered ", several bits represent that " if be triggered; how many shared bandwidth of the SRS of transmission is ", by that analogy, X bit represent " information of some other needs indication " thereafter.
What which two in this X configuration information need trigger with implicit information determined in the base station, for example, " if be triggered; which (0 or 1) the shared broach of the SRS of transmission is " in the above-mentioned configuration information and " if be triggered, sending still SRS repeatedly of SRS " is defined as pairing first configuration information of implicit information.And the configuration information of the SRS of remaining triggering UE is as second configuration information.
Referring to Fig. 3 (A) and Fig. 3 (B), first bit of implicit information triggers SRS for " 0 " is illustrated on No. 0 broach, is " 1 ": be illustrated in and trigger SRS on No. 1 broach; Second bit of implicit information is that " 0 " expression triggers a SRS, for " 1 " expression triggers repeatedly SRS.Wherein implicit information is corresponding mutually with first configuration information, the first corresponding configuration information of implicit information " 00 " is " send and trigger 1 time " on No. 0 broach, first corresponding configuration information of " 01 " is " send and trigger repeatedly on No. 0 broach ", first corresponding configuration information of " 10 " is " send and trigger 1 time " on No. 1 broach, first corresponding configuration information of " 11 " is " send and trigger repeatedly on No. 1 broach "
Determined the corresponding relation of implicit information and subframe numbers simultaneously, for example; The corresponding subframe 0 of implicit information " 00 ", " 01 " corresponding subframe 1, " 10 " corresponding subframe 2, " 11 " corresponding subframe 3.The base station sends to the UE that those need trigger SRS with the corresponding relation of above-mentioned SRS period of sub-frame, implicit information and the subframe numbers that presets and the corresponding relation of first configuration information and described implicit information.
Behind the UE access base station that needs trigger, first configuration information of this UE is determined in the base station to described UE, by above-mentioned first configuration information that presets and the corresponding relation of implicit information, determine the implicit information of this UE, for example, UE1 is determined to trigger SRS to be sent and triggers once on No. 0 broach, to UE2, determine on No. 1 broach, to send and repeatedly trigger, first configuration information that is UE1 is " send and trigger once " on No. 0 broach, first configuration information of UE2 is " repeatedly triggering on No. 1 broach ".The implicit information of UE1 is " 00 " so, and the implicit information of UE2 is " 11 ".
The base station also can send to UE with the corresponding relation of subframe numbers in SRS period of sub-frame, implicit information and the SRS period of sub-frame and the corresponding relation of first configuration information and implicit information;
Step 102:, determine the subframe of described implicit information correspondence by the corresponding relation of subframe numbers in the implicit information that presets and the SRS period of sub-frame;
Accept above-mentioned example, and referring to the description of Fig. 3 (B), if the implicit information of UE1 is " 00 ", first configuration information of UE2 is " 11 ", so according to the corresponding relation of above-mentioned implicit information that presets and subframe numbers, the subframe of the triggering SRS correspondence of UE1 is 0, and the subframe of the triggering SRS correspondence of UE2 is 3.
Step 103: on described subframe, trigger user equipment (UE), comprise second configuration information in the described trigger message by sending trigger message.
Referring to the description of step 102, accept above-mentioned example, the base station will be triggered UE1 and be triggered 1 time on the 0th frame, and will trigger UE2 and trigger repeatedly on the 3rd subframe.
The beneficial effect that the technical scheme that the embodiment of the invention provides is brought is: by carrying implicit information according to the relative position that triggers the PDCCH place, and base station side is informed the cycle of SRS subframe of the UE sub-district in the sub-district and the meaning of implicit information representative by system information, make UE according to the implicit information of the position calculation that receives PDCCH trigger message place subframe, can reduce the number of bits that each physical layer control channel trigger message takies.
