The embodiment of the invention 1 provides the method that realizes transfer of data in the TDD multicarrier system, and as shown in Figure 1, this method comprises:
Step 101: the ability information of obtaining user terminal;
Concrete, when accessing user terminal to network, can initiatively report oneself ability information; Also can obtain its ability information according to the feedback of this user terminal if will know the ability information of certain user terminal simultaneously by sending request to this user terminal; Certainly, the multiple ability information of user terminal of obtaining that exists in the prior art also is suitable in the scheme of present embodiment, does not repeat them here.
Step 102: the ability information according to user terminal is provided with new frame structure configuration relation on frequency domain and time domain;
Wherein, the ability information of described user terminal includes but not limited to following several at least: user terminal supports whether the ability of multi-carrier transmission, the transmitted power and the user terminal of user terminal support binary channels etc.; Be that how new according to the user capability information setting example describe frame structure configuration relation in detail with these several ability information below;
1) if user terminal is not supported multi-carrier transmission, then show its support single carrier transmission, this moment is when two-dimensional arrangement, only on same subframe, select the single allocation of carriers upstream or downstream resource in the multicarrier, promptly on same subframe, distribute to described user and be not more than a carrier wave as the upstream or downstream resource; As shown in Figure 2, wherein dotted line is represented is that subframe 1 with carrier wave 1 is set to descending sub frame, is used for the transmission of downlink data; Subframe 2 is a special subframe, and being arranged on hereinafter of this subframe can describe in detail, repeats no more herein; Subframe 3 is set to sub-frame of uplink, is used for transmission of uplink data, and the rest may be inferred;
2) if user terminal is supported multi-carrier transmission, then this moment is when two-dimensional arrangement, on same subframe, select the up and/or downlink resource of a plurality of allocation of carriers in the multicarrier, promptly on same subframe, distribute to a plurality of carrier waves of described user as up and/or downlink resource, concrete distribution can be operated according to the subframe uplink-downlink configuration of existing single carrier wave, the ascending-descending subframes structure of existing single carrier wave is also satisfied in the configuration of each carrier wave simultaneously when wherein disposing a plurality of carrier wave, specifically repeats no more herein; With following two kinds of situations is example, but is not limited thereto:
A, when user terminal is supported multicarrier, if on the service needed time domain that this user terminal is supported during continuous up and/or downlink resource, then when two-dimensional arrangement, distribute continuous uplink and downlink resource on the adjacent sub-frame in a plurality of carrier waves; As shown in Figure 3, wherein shown in the dotted line for being used for the subframe of service data transmission, wherein, the subframe 1 that carrier wave 3 is set is sub-frame of uplink, the subframe 2 that carrier wave 2 is set is sub-frame of uplink, subframe 3 and subframe 4 that carrier wave 1 is set are descending sub frame for sub-frame of uplink, subframe 5 and subframe 6, and the subframe 8 that carrier wave 3 is set is descending sub frame, and subframe 9 and subframe 10 that carrier wave 2 is set are descending sub frame; In the ascending-descending subframes structure that satisfies existing single carrier wave, adopt the different subframes of a plurality of carrier waves of described setting to be used for the transmission of business datum, thereby can well guarantee and the compatibility of existing LTE system;
B, when user terminal is supported multicarrier, if described user terminal is supported in the uplink and downlink subframe and receives and send data simultaneously, promptly this user terminal is supported the binary channels transmission, then when two-dimensional arrangement, the same subframe of described multicarrier is set to sub-frame of uplink and/or descending sub frame respectively, promptly on the same subframe of many each carrier waves, distributes up and/or downlink resource; Wherein, if the same sub of different carrier all is set to the upstream or downstream subframe, then can improve efficiency of transmission at the same sub while of a plurality of carrier waves service data transmission; Simultaneously, if the same sub of different carrier is set to uplink and downlink respectively, then user terminal can send and receive business datum simultaneously on this subframe; As shown in Figure 4, wherein dotted portion shows when the user supports binary channels, sends and receive business datum on same subframe simultaneously, has realized the binary channels transmission, and concrete setting and above-mentioned category-A seemingly do not repeat them here; Simultaneously, the uplink/downlink frames structure of each carrier wave all satisfies the frame structure when having the single carrier transfer of data now;
3) if comprised the power information of user terminal in the ability information of user terminal, i.e. this user terminal supported maximum up-link carrier number in same subframe, if then the transmitted power of described user terminal exceeds the transmitted power that its sub-district, place allows, be that transmitted power is limited, then when two-dimensional arrangement, on frequency domain, reduce employed carrier wave number in the same subframe or be provided with that this subframe is a sub-frame of uplink in the single carrier, promptly use single carrier to carry out the transmission of data; Perhaps on the one or more carrier waves on the time domain, a plurality of adjacent sub-frame of uplink are set, in order to send uplink business data; It should be noted that two kinds of settings can exist simultaneously; Can send upstream data by more sub-frame of uplink during subsequent data transmission, thus indirect reduction transmitted power, improved compatibility with existing LTE system;
In addition, on the basis of the frame structure configuration relation new, also can consider to carry out the setting of frame structure configuration relation according to the data volume and the delayed data of user terminal business datum to be transmitted based on the user capability information setting; For example, when the time-delay of described user terminal service data transmission is limited, then when two-dimensional arrangement, increase employed carrier wave number in same subframe, the adjacent sub-frames that the adjacent sub-frames that maybe sends the sub-frame of uplink of uplink business data is set to sub-frame of uplink, receive the descending sub frame of downlink service data is set to descending sub frame; When subsequent data transmission, if time delay is limited, then the downlink data of the upstream data of described transmission or reception is assigned to send on the adjacent sub-frame of uplink of the carrier wave of other carrier waves and these transmission data or descending sub frame on receive;
Certainly, when specifically implementing, after getting access to the ability information of user terminal, also need to consider other factors, as the neighbour disturb frequently, situation such as multisystem coexistence; Promptly when configuration up-downgoing resource, if the carrier wave both sides of being distributed, there are other carrier waves or other system carrier wave, then need to consider to face the uplink-downlink configuration of carrier wave frequently, avoid interference with disturbed: for example, should be assigned as descendingly according to this subframe of ability information of user terminal, the carrier wave of other system is up but face carrier wave frequently or face frequently, then can consider interference and the disturbed effect that it brings in minute timing.
In addition, it should be noted that above-mentioned when the two-dimensional frames structural arrangements being set concerning, if this user terminal is not supported the binary channels transmission, then at downlink resource when ascending resource is changed, between descending sub frame and sub-frame of uplink, dispose special subframe; Special subframe in the single carrier wave can be set to sub-frame of uplink or descending sub frame according to data transfer direction; Wherein, if when the same subframe on the multicarrier all is special subframe, DwPTS of special subframe (descending pilot frequency time slot) and UpPTS (uplink pilot time slot) can be configured on the different carrier, and reduce conversion times in time delay acceptable scope as far as possible; What particularly note is that a plurality of special subframes on the same user terminal multicarrier can adopt different special subframe configurations, and (length that is DwPTS, GP and UpPTS can be different; Can make different selections according to different situations in the specific implementation, not repeat them here.
Step 103: send indication signaling to user terminal, notify this user terminal to adopt described new frame structure configuration relation to carry out the transmission and the reception of business datum.
Concrete, when user terminal sends indication signaling, mainly be to send to user terminal, but be not limited thereto by high-level signaling, broadcast or descending control signaling; And, all do not have situation about changing in a short time for ability of user terminal and business to be transmitted, can periodically carry out the setting of new frame structure configuration relation, be notified to described user terminal then, thereby can effectively reduce Signalling exchange, save system resource; Wherein, comprise carrier index and subframe numbering in the described indication signaling at least, promptly informing user terminal is numbered transmission or reception business datum on indicated carrier wave and the subframe in described carrier index and subframe; Certainly, also can in indication signaling, comprise other guide, repeat no more herein;
