For the problems referred to above existed in correlation technique, illustrating below in conjunction with alternative embodiment, this alternative embodiment combines above-described embodiment and optional embodiment thereof.

Describing embodiments of the present invention in detail below with reference to embodiment, to the present invention, how application technology means solve technical problem whereby, and the process that realizes reaching technique effect can fully understand and implement according to this.

Time orientation in unauthorized carrier wave is divided into some cycles by this alternative embodiment, cycle is T, channel P (being equivalent to above-mentioned predetermined channel) is set in each cycle T, total duration of P is that (T is multiplied by 5% to Tx5%, follow-up for the ease of describe be designated as t), in P channel, base station can send data signal and not perform CCA process.

Wherein, P channel is at frequency domain, it is possible to be full bandwidth, it is also possible to be fractional bandwidth, for instance part physical Resource Block (PRBs) is taken as P channel. P channel is in time domain, it is possible to be continuous duration be t, it is also possible to be the summation of the duration that several are little be t.

P channel is in any one duration T, and the total duration of P channel not can exceed that t.

Optionally, in P channel, configuration sends about fixed sequence, and the original position of P channel is determined by detecting about fixed sequence in other base stations. And arrange the position that described sequence sends, for instance the OFDM symbol position in channel P. A kind of PSS/SSS that preferably can select 2 OFDM symbol transmission LTE in P channel. Such as when cycle T is equal to (or more than) 20ms, it is possible to arranging P channel duration is 1ms, equal to a subframe of LTE, now can send relevant data according to LTE standard. Such as can sending PSS/SSS according to the subframe 0 of LTEFDD or subframe 5, PSS/SSS now can about be decided to be unified sequence.

Optionally, P channel can be divided into several OFDM symbol in time domain. Preferably, these OFDM symbol are divided into 3 parts: up (transmission data division), descending (reception data division), and conversion time portion. Further, according to P channel difference purposes, above-mentioned 3 parts can configure and only use one of them. Specifically it is referred to described in embodiment.

P channel can include the signal of identification purposes, such as in the position of P channel agreement, send the different sequences of agreement, purposes with the current P channel (or P channel of next cycle) of sequence identifier, or structure (also comprises those signals with regard to P channel, how these signals send), receive base station and can first detect the sequence of tag slot, then the purposes of P channel is known, thus base station determines the processing mode of oneself, the resource such as receiving/sending, receives/sends those signals.

The purposes of P channel includes: describe P channel receives signal section, transformation time part and send data division distribution and with or without; The type sending signal in P channel is described.

Time resource in P channel divides according to OFDM symbol, optional, the OFDM symbol duration OFDM duration equal to LTE.

When P channel is 1ms duration, P channel determines that 2 OFDM symbol are to send the PSS/SSS of LTE, first alternatively/second OFDM symbol carrying.

P channel is divided into the physical resource that M group is orthogonal, and each group of physical resource all includes all of OFDM symbol of P channel. Each group of physical resource takies RE quantity in each OFDM of P channel and is at least L. Wherein, the detection of the signal energy in L RE meets the minimum threshold that the unauthorized carrier wave of regulation does.

The sequence sent in P channel sends according to the PSS/SSS structure of LTE, the sequence of the PSS/SSS in the main plot (primarycell, referred to as Pcell) that sequence is corresponding equal to the unauthorized carrier wave in P channel place; It is one or more that the reference signal sent in P channel includes in CRS, CSI-RS, PRS.

The structure of P channel includes one of the following:

Structure 1:P channel includes about fixed sequence transmitting portion, data or reference signal transmitting portion. In structure 2:P channel, time sequencing includes transmitting portion, changes time portion, receives part, and wherein conversion time portion can configure. In structure 3:P channel, time sequencing includes reception part, changes time portion, transmitting portion, and wherein conversion time portion can configure. Structure 4:P channel include about fixed sequence transmitting portion, conversion time portion, transmission/reception section. For above-mentioned 4 kinds of structures, if P channel completely cannot be divided, P channel can send Seize ACK message and (be used for so that unauthorized carrier wave is called busy after transmission, thus avoiding other base stations or system to seize, Seize ACK message is different from occupied information, it is possible to use occupied information substitutes). For conversion time portion, if existed in P channel, then conversion time portion is divided into two kinds of situations. The first situation is, conversion time portion is different for different base station, if time portion need not be changed to adjust hardware in the base station such as having, then these base stations need to send Seize ACK message in conversion time portion, realize unauthorized carrier wave for busy state with help. For needing the base station of conversion time portion, then it is carried out hardware adjustment in this part. The second situation is, changes time portion, so base station all can only perform hardware adjustment, it is impossible to send data. Now make it possible to other system and seize away unauthorized carrier wave, but this mode still can use (both not to have had different system) when same system.

The various piece of said structure can at P channel internal recycle repeatedly. Base station can also repeatedly perform the process of correspondence.

For structure 1: described data or reference signal transmitting portion, described data include taking the occupied information for unauthorized carrier wave that the usufructuary base station of unauthorized carrier wave sends, or plan the expectation taking the base station transmission of the unauthorized carrier wave occupied information for unauthorized carrier wave. The base station that described reference signal transmitting portion is mainly used in planning taking unauthorized carrier wave do not rob account for unauthorized carrier wave time, it is that subordinate UE performs to measure and synchronize that base station sends reference signal.

For structure 2: the base station and/or the plan that have taken unauthorized carrier wave take the base station of unauthorized carrier wave and send for unauthorized carrier occupancy information in transmitting portion and/or expect the occupied information for unauthorized carrier wave. In described reception part, base station receives the occupied information for unauthorized carrier wave of other base stations transmission and/or expects the occupied information for unauthorized carrier wave.

For structure 3: base station (includes plan and uses the base station of unauthorized carrier wave, and other base stations take situation for unauthorized carrier wave in unclear unauthorized carrier wave) in described reception part, receive the occupied information for unauthorized carrier wave of other base stations transmission and/or expect the occupied information for unauthorized carrier wave, to determine that oneself the expectation occupied information for unauthorized carrier wave is (for taking the base station of unauthorized carrier wave and having formulated the base station expecting the occupied information for unauthorized carrier wave, the occupied information of other base stations can also be received in acceptance division tap, thus adjusting the occupied information of oneself).

In described transmitting portion, base station sends for unauthorized carrier occupancy information and/or expects the occupied information for unauthorized carrier wave.

P channel include about fixed sequence transmitting portion, conversion time portion, transmission/reception section.

For structure 4: base station is in about fixed sequence transmitting portion, send the about fixed sequence (can be used for mark P channel or synchronize purpose) identifying this P channel or next P channel, then the purposes according to P channel, send the occupied information for the unauthorized carrier wave and/expectation occupied information for unauthorized carrier wave in transmission/reception section, or send reference signal. In this case, it is mainly used for not robbing and accounts for unauthorized carrier wave, but plan uses the base station of unauthorized carrier wave.

Conversion time portion, is mainly used for adjusting base station from the RF hardware state receiving transmission (or from being sent to reception). If hardware is advanced, then this function can not need. So this part is optional.

The application is except 4 kinds of above-mentioned P channel architectures, can also by identical for the structure with existing LTE subframe of P channel design, such as structure can be the subframe structure (subframe 0 under such as FDD structure) comprising major-minor synchronization in LTE, or comprise the subframe structure (subframe 0 under such as TDD structure of main synchronization,) or comprise the subframe structure (subframe 1 under such as TDD structure) of auxiliary synchronization or common subframe (subframe 1 of such as FDD).

About fixed sequence transmission for above-mentioned P channel is also optionally in limited instances, such as when the position using the subframe timing of main carrier of unauthorized carrier pairings to describe P channel, sequence just can not send, now website determines existence and the cycle of P channel by receiving corresponding P channel configuration signaling, and the subframe timing of reference main carrier determines the concrete time-domain position of P channel.

P channel is used for base station, by according to following flow performing.

First base station detects whether unauthorized carrier wave exists P channel, concrete, base station (include robbing account for the usufructuary base station of unauthorized carrier wave and/or do not rob account for the usufructuary base station of unauthorized carrier wave) the about fixed sequence of transmission in P channel can be detected, thus judging whether unauthorized carrier wave has P channel; If had, base station (include robbing account for the usufructuary base station of unauthorized carrier wave and do not rob account for the usufructuary base station of unauthorized carrier wave) will use P channel, specifically used mode, the base station of the different conditions structure according to different purposes or purposes and P channel, will have each different use flow processs. It is referred to the description of above-mentioned P channel architecture part; Without, base station will perform according to following two mode respectively: first mode, rob and accounted for the unauthorized carrier wave usufructuary base station unauthorized carrier cycle of division and configure P channel, and in P channel, performed the operation of correspondence as desired according to the description of foregoing moieties. Second mode, does not rob the base station accounting for unauthorized carrier wave, and the right to use performing to seize unauthorized carrier wave also constantly detects whether P channel exists simultaneously, if after getting the right to use, does not still find P channel, then this base station is follow-up performs according to first kind of way. Or do not rob and account for unauthorized base station simultaneously unauthorized this base station divides unauthorized carrier cycle and also configures P channel for time idle, and in P channel, perform the operation of correspondence as desired according to the description of foregoing moieties.

In literary composition, P channel is actual is physical resource, so P physical resource can also be become. Website belonging to herein includes base station, it is also possible to be UE.

In this alternative embodiment, base station is changed to terminal, and such scheme is equally applicable.

In one alternate embodiment, assume that base station 1 is first to begin to use the base station (this can determine first base station beginning to use unauthorized carrier wave according to operator's actual deployment situation of this geographical position A) of unauthorized carrier wave in the A of geographical position, cycle T is determined in base station 1, and original position starts to determine channel P continuous in time in cycle T, the duration of P is t, and full bandwidth. Channel P is divided by base station 1 according to the OFDM symbol duration (other OFDM symbol durations it is also possible that) of LTE. Sending the sequence of agreement in the OFDM symbol that base station 1 is arranged in channel P, this sequence determines the position of P channel in unauthorized carrier wave for other base stations. Such as base station 1 determines that cycle T is 20ms, and now the duration t of P channel is 1ms, and according to the standard of LTE, P channel is exactly equal to a subframe duration, is divided into 14 OFDM symbol. Figure 11 is the schematic diagram one of P channel according to embodiments of the present invention, as shown in figure 11, for a schematic diagram of P channel.

P channel can be further divided into the P channel of different purposes according to the cycle, the P channel be such as divided into the P channel sending data, receiving data, or the P channel of other purposes (the P channel that the P channel of such as synchronized tracking, RRM measure), apparent from the difference of purposes, the data form sent in P channel is different.

It is alternatively possible to the more different sequences of agreement identify the P channel of different purposes respectively. Such as sequence 1 sends in the P channel of synchronized tracking, sequence 2 sends at the P channel receiving data, and so other base stations can according to the difference of sequence, it is determined that perform the operation of correspondence in corresponding P channel. The transmission position that sequence is concrete in P channel can be arranged in advance, is so easy to receiving terminal and determines P channel starting point.

Alternatively it is also possible to adopt sequence to describe the P channel usage of correspondence in different P channel frequency positions.

Alternatively it is also possible to determined the purposes of P channel by the numbering of different cycles. The numbering of P channel also sends in P channel.

Base station is when using unauthorized carrier wave, base station is by detecting P channel determines whether there is P channel in unauthorized carrier wave, if existed, then base station can use P channel carry out related data transmission or reception and need not perform CCA process, for instance sends and measures signal, synchronizing signal, take the negotiation information of unauthorized carrier wave. Concrete, P channel can be the resource that many base stations can use, so needing to ensure that the orthogonality of resource between multiple base station or code division mode use. Such as P channel is divided into several little resources (can according to the base station number using unauthorized carrier wave while vicinity), each resource sets up one-to-one relationship for subordinate community, base station, and then the resource location oneself sent in P channel is determined in base station according to this corresponding relation. If it does not, base station can divide and sends P channel according to the cycle divided.

Can use if P channel is multiple base station, if send relevant reference signal be used for measuring, when synchronizing purpose, the RE position of the reference signal that different base station sends can be orthogonal. The UE of such different base station subordinate all can each receive the measurement of corresponding reference signal.

In another alternative embodiment, the signal describing P channel is sent as UE.

The purposes of P channel is different, and the corresponding signal that sends also is different. When P channel is used for sending measurement, synchronizes (including essence synchronization), due to receive data in P channel to as if the subordinate terminal of base station, so P channel has only to consider how base station sends, it is not necessary to consider base station reception.

P channel can carry different reference signals according to different demands, it is also possible to carry multiple reference signal and sequence simultaneously. time such as utilizing P channel to carry out RRM measurement, base station can be configured in P channel, send CRS and/or CSI-RS, the sequence for synchronizing can also be increased, such as, PSS/SSS in LTE, this is primarily to help UE and base station synchronization, is then easy to the RE location resolution of CRS and/or CSI-RS. UE can (this parameter can be solidified by agreement or inform UE by the cycle T that arranges according to base station, so it is easy to UE and P channel detected), detection base station sends sequence at P channel, and (sequence can inform UE, or when being PSS/SSS such as infructescence, base station agreement adopts the sequence identical with the PSS/SSS of the Pcell of UE), then can determine that P channel original position according to sequence, such as initial OFDM symbol position, thus calculating other OFDM symbol positions in P channel, thus mapping pattern according to reference signal further, determine the RE position of reference signal, the final reference signal obtained in P channel. obviously, profit this alternative embodiment in P channel time, base station need not perform CCA mechanism, thus can so that the situation accounting for unauthorized carrier wave be not being robbed in base station, unauthorized carrier wave sends data etc. by P channel, the UE of such base station subordinate also is able to carry out RRM measurement by P channel for the unauthorized carrier wave being likely in the future use, so, when base station is robbed and is accounted for unauthorized carrier wave, according to the RRM measurement result of UE before, can quickly be determined as those UE configuration and use unauthorized carrier wave. similar, the UE of base station subordinate also is able to be undertaken synchronizing and synchronize to maintain by P channel, so when base station is robbed and accounted for unauthorized carrier wave, UE can quick and unauthorized carrier synchronization so that base station can begin to scheduling UE data transmission the very first time, similar, the UE of base station subordinate also is able to carry out CSI measurement by P channel, so when base station is robbed and accounted for unauthorized carrier wave, the MCS grade of scheduling directly can be determined in base station according to UE by the CSI measurement result of P channel, so that the head that base station is UE passes the MCS grade that data acquisition is suitable, promote efficiency of transmission.

Wherein, the cycle T of base station configuration is sent to UE by the Pcell of UE. The concrete configuration message using Scell, or use the activation/deactivation information of Scell to notify UE. In the configuration message of Scell, such as increase new parameter T or the value of the bit characterising parameter T in the MACCE of the activation/deactivation of SCell.

Further, in order to avoid all UE of base station subordinate perform measurement for P channel in unauthorized carrier wave, base station can select part UE, example base station utilizes special RRC message notification section UE to perform measurement for P channel by Pcell, can also notify to send, in cycle of P channel or P channel, the reference signal (or relevant information of reference signal configuration) sent in sequence or P channel simultaneously. The UE so only receiving base station notice just can perform above-mentioned measurement, thus reducing the impact of the UE for inapplicable unauthorized carrier wave.

In another alternative embodiment, describe and between base station, utilize P channel to interact.

Rob and account for the usufructuary base station 1 of unauthorized carrier wave, it is possible to sent the occupied information oneself taking unauthorized carrier wave by P channel, for instance take duration (the taking continuously) information of unauthorized carrier wave and/or take the subframe drawing information of unauthorized carrier wave.

The occupied information that the base station 2 accounting for unauthorized carrier wave is able to receive that base station 1 sends in P channel will be robbed, then calculate the occupied information of oneself according to occupied information, then this occupied information is sent in P channel. The concrete occupied information calculating oneself, for instance, the subframe pattern oneself taking unauthorized carrier wave is determined in base station 2 in the subframe except take the subframe pattern of unauthorized carrier wave except base station 1, form subframe drawing information, and send in P channel.

Different base station can also be arranged and take the subframe of a series of unauthorized carrier wave according to orthogonal subframe pattern, such as adjacent bus station has N number of base station, total N number of orthogonal subframe pattern, and it is numbered 0��N-1, a series of subframes in holding time direction can be carried out in each base station according to numbering, and number information (or about fixed sequence of numbering correspondence) is sent at P channel. Such as each orthogonal subframe pattern adopts cycle, skew to describe. Skew is 0��N-1, with the subframe 0 of frame 0 for skew 0.

Figure 12 is the schematic diagram one including P channel that is up, descending and that protect interval according to embodiments of the present invention, and as shown in figure 12, the design of P channel includes up, descending and protection interval. Owing to P channel is that multiple base station shares, so from different base station side, it is possible to some base stations regard up as, and other base stations are descending really, for the ease of describing, can be labeled as transmitting portion, reception part, conversion time portion in the application. Wherein conversion portion is optional. Such as, after hypothesis base station 1 is robbed and accounted for unauthorized carrier wave, base station 1 can utilize the resource of transmitting portion to send the occupied information of oneself in P channel, and the acceptance division at P channel taps receives the occupied information that will take unauthorized carrier wave that other base stations send. Figure 13 is the schematic diagram two including P channel that is up, descending and that protect interval according to embodiments of the present invention, and as shown in figure 13, P channel can also be designed according to Figure 13. Conversion time portion now is also optional, and actually deleting the only performance being also to work slightly affects.

In the part resource of the transmitting portion of P channel, base station optionally sends the sequence of agreement, is so easy to other base stations detection sequence and determines P channel position.

In another alternative embodiment, it is provided that another kind of interaction mechanism.

Figure 14 is the schematic diagram two of P channel according to embodiments of the present invention, as shown in figure 14, P channel is divided into 3 parts: tag slot, it is used for identifying the purposes (in similar and above-mentioned alternative embodiment, being may determine that purpose and the purposes of this P channel by the information sent in tag slot) of this P channel. Conversion time portion, is primarily to reserved regular hour section and makes base station can adjust the power amplifier state of transmission/reception or resolve the information of tag slot, partly as optional part, namely can also should be absent from. Transmission/reception section, is used for sending or receiving data division, and the purposes that this part identifies with tag slot is consistent. How three parts dispose in P channel, not strict restriction, but should be standardized, and such base station can know tag slot physical location in P channel accurately, and Figure 14 simply show the signal of a kind of optimum. First base station receives the tag slot information in P channel, knows the purposes of P channel, thus receiving in P channel according to purposes or sending data.

This alternative embodiment can also use the use between base station and subordinate UE.

In another alternative embodiment, being to above-described embodiment improvement, this alternative embodiment is defined as the next purposes by the P channel arrived for the P channel that the tag slot of the P channel in above-described embodiment identifies. Such main purpose is, can leave more sufficient parsing and data processing time to be sent (size approximates cycle T duration) for the base station (or UE) that disposal ability is low. Now the conversion time portion in P channel is also optional.

Base station (or UE) receives the information of tag slot in current P channel, it is determined that the purposes of P channel next time, and as needed in sending/receive data in next P channel, and these data can the occupied information of unauthorized carrier wave.

In another alternative embodiment, it is provided that another kind utilizes P channel to carry out the scheme that unauthorized carrier occupancy information is mutual.

The resource of P channel is divided into the physical resource that M group is independent, and wherein M is the maximum base station interacting base station quantity (value that different bandwidth is likely to M is different) supported. the independent physical resource dividing of M group needs to meet orthogonal principle. further, M group independent resource any one group can both cover all OFDM symbol resources of P channel, and to ensure to make other system when detecting P channel, testing result is channel busy, and other system thus can be avoided to seize unauthorized carrier wave during P channel. the RE quantity that M group independent resource any one group takies in an OFDM symbol at least meets following condition: namely in one OFDM symbol of hypothesis when sending signal be more than or equal to the RE of L, other websites will detect that this OFDM symbol is busy (this concrete L number and the testing conditions of definition in standard, thresholding size relevant (different bandwidth is difference slightly), these information can find in standardization specifications of surveys, so L can obtain, different bandwidth is likely to there is different values), so may determine that the RE quantity that M group independent resource any one group takies in an OFDM symbol is at least L.

A kind of design of M group independent resource, the RE quantity distributed in each OFDM symbol frequency domain direction of P channel is L (can also more than L), and wherein L RE can be continuous, it is also possible to discrete, L RE of each OFDM symbol can be identical in the position of frequency domain, it is also possible to orthogonal. The data sent in each group of resource, it is possible to be the sequence provided in advance. Figure 15 is the schematic diagram that L RE according to embodiments of the present invention is continuous and each OFDM symbol frequency domain is orthogonal. The discrete capacity of resisting disturbance that can promote channel with time domain discrete of frequency domain, but also can increase complexity, it is necessary to and compromise considers.

M group resource needs and M base station suggestion corresponding relation, for instance M group resource is numbered respectively, and the resource group not sending data in P resource is first detected in base station, then selects one or more resource group to use it, and sends data in corresponding resource group.

In this alternative embodiment, it is also possible to a reserved public resource carrys out sequence in advance, it is simple to base station finds the position of P channel. Such as reserving the position of transmission LTEPSS/SSS in advance, each base station can send the PSS/SSS of oneself in this position. The energy of PSS/SSS or sequence can be detected to determine the position of P channel in base station.

In sum, this alternative embodiment gives and need not perform the CCA channel that just can directly use in a kind of unauthorized carrier wave, by this channel, can realize taking between base station the mutual of unauthorized carrier wave, especially the base station between different operators so that the base station between different operators is possibly realized alternately and efficiency is very high. Can also realize base station vacant to unauthorized carrier wave time just send relevant reference signal, realizing UE uses the channel quality condition of unauthorized carrier wave to measure in advance for own base station in the future, thus promoting base station to take the service efficiency after unauthorized carrier wave.
