According to redundancy versions corresponding with the frame number information, it is determined as the sub-block that starting sends position；
Since the sub-block determined, the PBCH information sequence is cycled through.
Wherein, above-mentioned multiple continuous sub-blocks can be to the multiple sub-blocks after PBCH signaling channel coding, obtained.When superfluous After remaining version determines, so that it may the corresponding sub-block of the redundancy versions is determined, thus using the sub-block as starting transmission position, from true The sub-block made starts, and cycles through the PBCH information sequence.
In present embodiment, the PBCH information sequence obtained after channel coding is carried out to PBCH signal, is segmented into multiple Continuous sub-block.When sending PBCH information sequence, transmission can be started the cycle over from any one sub-block.Different can be risen It originates and position is sent to be defined as different redundancy versions, to indicate different frame number information using redundancy versions.
Optionally, the PBCH information sequence includes 4 continuous sub-blocks.
In present embodiment, PBCH information sequence can be divided into 4 continuous sub-blocks, such as: as shown in Figure 4.Coding PBCH information sequence afterwards not necessarily sends from initial position when sending, but can start the cycle over from any one sub-block It sends.It is sent until all information sequences.Initial positions different so is just defined as different redundancy versions.And 4 The value of corresponding 4 redundancy versions in a different initial position is as shown in Figure 5.From figure 5 it can be seen that n can be usedrdIndicate superfluous The value of remaining version, as 0 (n of redundancy versionsrd=0) when, PBCH information sequence is sent since initial position sub-block 0, is successively sent Sub-block 0,1,2,3, to send complete PBCH information sequence.1 (n of redundancy versionsrd=1) when, PBCH information sequence is from sub-block 1 Start to send, successively transmission sub-block 1,2,3,0, to send complete PBCH information sequence.2 (n of redundancy versionsrd=2) when, PBCH information sequence is sent since son 2, successively transmission sub-block 2, and 3,0,1, to send complete PBCH information sequence.Redundancy Version 3 (nrd=3) when, PBCH information sequence is sent since sub-block 3, successively transmission sub-block 3, and 0,1,2, to send complete PBCH information sequence.
It can indicate the information content of 2 bits, by above-mentioned redundancy versions in this way accurately to indicate the first of radio frames Part serial number information.
Optionally, the period of the PBCH signal is 4 of the period of synchronous access signal collection belonging to the PBCH signal Times；
In the same period of synchronous access signal collection, the redundancy versions for sending the PBCH signal are identical；Same In the different cycles of step access signal collection, the redundancy versions for sending the PBCH signal are different.
Such as: as shown in fig. 6, the period of PBCH signal is 8 radio frames, such as 80ms, which is synchronous access signal 4 times of the period of collection.Within the period of a PBCH signal, 4 transmissions of identical synchronous access signal collection.An and PBCH letter Number period in synchronous access signal collection 4 transmission when, PBCH therein is using different redundancy versions.As shown in fig. 6, So as to indicate that current sync accesses position of the signal collection in 8 radio frames with redundancy versions, i.e. removed in 10 bit informations 7 bit informations of highest order and 2 bit information of residue except significant bits information.
In present embodiment, it may be implemented the different sending cycles for synchronizing access signal collection being mapped to PBCH signal not With in redundancy versions, to achieve the purpose that transmit remaining 2 bit frame numbers using redundancy versions.Such as: with radio frames For serial number 0~1023, after user terminal receives PBCH signal, first by detection PBCH signal, 7 ratios of highest order are obtained Special information, uses nMIBIt indicates, originally obtained intermediate 2 bit informations by detecting different redundancy versions, for nrdIt indicates, and Significant bits information can be determined according to synchronous access signal collection position.
Such as: if the period of 2 radio frames of synchronous access signal collection, since even frame, which accesses signal Frame number where collection can be obtained by following formula:
nf=nMIB×8+nrd×2
If the period of 2 radio frames of synchronous access signal collection, the synchronization accessed signal collection institute since odd-numbered frame Frame number can be obtained by following formula:
nf=nMIB×8+nrd×2+1
In the present embodiment, the complete sequence number letter that radio frames are accurately indicated to user terminal may be implemented through the above steps Breath, to improve the accuracy of frame synchronization.
