Background technology

With sharply increasing for message volume, the capacity of the existing wireless frequency spectrum for distributing to mobile service can not Satisfaction require that.In the 3GPP Rel-13 stages, one kind is referred to as LAA (licensed-assisted access, the access of auxiliary Technology) mechanism be introduced into.In LAA mechanism, the transmission of mobile communication can carry in unlicensed spectrum, such as 5GHz Frequency range.And these unlicensed spectrums are presently mainly that the systems such as Wi-Fi, bluetooth, radar, medical treatment are using.

Due to the diversity and complexity of system in unlicensed spectrum, directly LTE (Long Term Evolution, length Phase evolution) mechanism be used for unlicensed spectrum on be the security and connection that can not ensure user stability.Therefore, exist In LAA mechanism, by CCA mechanism, the access in unlicensed spectrum is helped using mandate frequency spectrum.At present, in unauthorized frequency If using LTE in spectrum, system can have two kinds of working methods, and one kind is supplement descending (SDL, Supplemental Downlink), i.e. only downlink transfer subframe；Another kind is TDD (Time Division Duplex, time division duplex) pattern, Both comprising descending sub frame, sub-frame of uplink.It can only be used by carrier aggregation technology (such as Fig. 1 institutes to supplement the fact that descending Show)：

And in existing LAA systems, LAA systems first have to perform LBT (Listen before unauthorized channel is taken Before Talk, listem-before-talk) mechanism.Need to do CCA detections first to judge whether channel is idle.If it is determined that channel Free time, LAA systems can be with busy channels, if it is determined that channel busy, LAA systems need that after waiting channel idle letter could be taken Road.

LBT mechanism is divided into two kinds at present, and a kind of is based on frame structure (FBE, Framed based equipment) LBT mechanism, LBT cycle is fixed that CCA (channel clear assessment) time is under this mechanism Each cycle most starts.Another is the LBT mechanism based on load (LBE, Load based equipment), should Mechanism cardinal principle be load to up to when, at once carry out Channel Detection, if detection channel idle, at once send data industry Business；If detecting channel busy, a number N is randomly choosed, in ensuing Channel Detection Time, if detecting channel busy, Then N is constant, if detecting the channel spare time, N-1, when N is kept to 0, then can send data.

Either which kind of LBE mechanism, due to detecting that channel is not busy and can be likely to occur with the time of busy channel in office When carve, i.e. the not no boundary alignment with LTE subframe, then terminal can not learn received since which position come on CCA Down control channel PCFICH, while can not also learn the size of control area, thus can not also learn PCFICH (Physical Control Format Indicator Channel, Physical Control Format Indicator Channel), PHICH (Physical Hybird ARQ Indicator Channel, Physical HARQ Indicator Channel) and PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) etc. down control channel original position, the institute of below figure 2 Show, and then lead to not receive the control signaling carried on down control channel PCFICH, PHICH and (E) PDCCH, with basis The control signaling carries out associative operation.

As shown in figure 12, the equipment with base station functions can also detect subframe in channel idle and detect down channel sky Idle, it is reservation signal to send preserved signal to terminal, so that terminal is used to indicate in preserved signal The First ray value of first area length and the second sequential value put for indicating first start bit, obtain first area length and First start bit is put：

Under this approach, due in LAA systems, after CCA detections are finished, after determining that channel can take, having The equipment of base station functions may send reservation signals, therefore, can be by reservation signals come implicit The size and first start bit for indicating the first control area in unlicensed spectrum are put；

Specifically, the first control area can implicitly be indicated by the different sequences of reservation signals Length and first start bit put, as shown in figure 12, it is assumed that reservation signals be a length be 10 sequence, then, If the front two for preassigning sequence is used to refer to the length i.e. front two sequence of 10 bit sequence of the first control area Sequential value is First ray value, behind 8 first start bits for being used for the first control area put latter eight of i.e. 10 bit sequence The sequential value of sequence is the second sequential value, and this definition is sent to terminal, so, terminal can in the form of configured information The length of the first control area can be obtained according to the sequential value of front two sequence by implicitly knowing, and according to rear 8 bit sequence Sequential value can obtain first start bit and put, as shown in figure 12, in fig. 12, when the sequential value of current two bit sequence is 00, eventually End will know that the first control area length is 1 OFDM symbol according to configured information；The sequential value of current two bit sequence is 01 When, terminal will know that the first control area length is 2 OFDM symbols according to configured information；The sequential value of current two bit sequence For 10 when, terminal will know that the first control area length is 3 OFDM symbols according to configured information；The sequence of current two bit sequence When train value is 11, terminal will know that the first control area length is 4 OFDM symbols according to configured information；When after 8 bit sequences Sequential value when being 00000000, after terminal will know that first start bit is put and is reservation signals according to configured information The 1st OFDM symbol, when rear 8 bit sequence sequential value be 00000001 when, terminal will know that first according to configured information Original position is the 2nd OFDM symbol after reservation signals, the like.

Certainly, the sequence shown in Figure 12 is only example, the length of sequence be probably it is different (such as can be 12 Deng), the place that the sequence that the first control area size and first start bit are put is indicated in sequence is also likely to be different, example Such as：When the length of reservation signals is still 10 sequences, if the front three for preassigning sequence is used to refer to first The length of control area is that the sequential value of first three bit sequence of 10 bit sequence is First ray value, and 2 are used for first after inverse The sequential value that the first start bit of control area puts 2 bit sequences after the i.e. inverse of 10 bit sequence is the second sequential value, and should Definition is sent in the form of configured information to terminal.

Technical scheme is described in detail above in association with accompanying drawing, can allow in the clear and definite CCA subframes of terminal The original position and length of control area, to be accurately received down control channel in time, and then descending control are obtained exactly The control signaling carried on channel.
