Background
In an existing LTE (Long Term Evolution ) system, data transmission is generally performed by using a single carrier resource; in a TDD (Time Division Duplex) mode, a base station configures a single carrier by using a frame structure specified in an LTE system, and agrees on a configuration relationship between an uplink subframe and a downlink subframe with a user terminal, as shown in table 1, where D denotes a downlink subframe, S denotes a special subframe, and U denotes an uplink subframe; and, for different base station cells, different frame structure configuration relationships can be adopted.
TABLE 1
However, in the LTE multi-carrier system, there may be multiple carrier resources between the base station and the user equipment for data transmission, and if the frame structure configuration manner in the existing single carrier transmission is still adopted, when the base station allocates uplink and downlink resources to the user equipment, the base station can only allocate resources based on one or more of multiple carriers, but is limited by the existing uplink and downlink frame structure configuration of the system, and the compatibility is often poor, and the requirements in the aspects of service, data volume, transmission power, system delay, and the like of the LTE multi-carrier system cannot be met: for example, the base station can only allocate resources to the user terminal according to the TDD mode frame structure configuration on different subframes, and cannot continuously allocate multiple uplink resources or multiple downlink resources according to the service requirement; or the user terminal can only allocate and schedule uplink or downlink resources in the same subframe, and the uplink and the downlink cannot exist simultaneously.

Detailed Description
The basic idea of the invention is to establish a two-dimensional uplink and downlink frame structure configuration relationship in the frequency domain and the time domain based on the capability of the user terminal, and inform the user terminal of the two-dimensional uplink and downlink frame structure configuration relationship, so that the service is transmitted and received between the base station and the user equipment on the time-frequency resources allocated and scheduled based on the two-dimensional frame structure configuration relationship, thereby ensuring the compatibility with the existing LTE system in the aspect of multi-carrier service data transmission, and greatly improving the flexibility of the TDD mode in the multi-carrier system.
It should be noted that, in the embodiment of the present invention, the two-dimensional configuration relationship between the uplink and downlink frame structures refers to that both time domain and frequency domain are considered when allocating uplink and downlink resources on a subframe; hereinafter, the new frame structure configuration relationship is referred to.
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; it is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
step 101: acquiring capability information of a user terminal;
specifically, when the user terminal accesses the network, the user terminal can actively report the own capability information; meanwhile, if the capability information of a certain user terminal needs to be acquired, the capability information can be acquired according to the feedback of the user terminal by sending a request to the user terminal; of course, various methods for obtaining the capability information of the ue in the prior art are also applicable to the solution of this embodiment, and are not described herein again.
Step 102: setting a new frame structure configuration relation in a frequency domain and a time domain according to the capability information of the user terminal;
wherein, the capability information of the user terminal at least includes but is not limited to the following: the capability of the user terminal for supporting multi-carrier transmission, the sending power of the user terminal, whether the user terminal supports dual channels or not and the like; the following describes how to set a new frame structure configuration relationship according to the user capability information in detail by taking the several types of capability information as examples;
1) if the user terminal does not support multi-carrier transmission, the user terminal only supports single-carrier transmission, and at the moment, when the user terminal is in two-dimensional configuration, only a single carrier in the multi-carrier is selected on the same subframe to allocate uplink or downlink resources, namely the user terminal is allocated to the same subframe to be not more than one carrier as the uplink or downlink resources; as shown in fig. 2, a dotted line indicates that subframe 1 of carrier 1 is set as a downlink subframe for transmission of downlink data; subframe 2 is a special subframe, and the setting of the subframe will be described in detail hereinafter, which is not described herein again; setting the subframe 3 as an uplink subframe for transmitting uplink data, and so on;
2) if the user terminal supports multi-carrier transmission, then when configuring two-dimensionally, selecting multiple carriers in the multiple carriers on the same subframe to allocate uplink and/or downlink resources, that is, allocating multiple carriers to the user on the same subframe as uplink and/or downlink resources, wherein the specific allocation can be operated according to the subframe uplink and downlink configuration of the existing single carrier, and the configuration of each carrier when configuring multiple carriers also meets the uplink and downlink subframe structure of the existing single carrier, which is not described herein again; the following two cases are taken as examples, but not limited thereto:
A. when a user terminal supports multiple carriers, if the service supported by the user terminal needs continuous uplink and/or downlink resources in a time domain, distributing the continuous uplink and downlink resources on adjacent subframes in the multiple carriers during two-dimensional configuration; as shown in fig. 3, a subframe for transmitting service data is shown by a dotted line, where subframe 1 of carrier 3 is set as an uplink subframe, subframe 2 of carrier 2 is set as an uplink subframe, subframes 3 and 4 of carrier 1 are set as uplink subframes, and subframes 5 and 6 are set as downlink subframes, subframe 8 of carrier 3 is set as a downlink subframe, and subframe 9 and subframe 10 of carrier 2 are set as downlink subframes; different subframes of the multiple set carriers are adopted for transmitting service data while the uplink and downlink subframe structure of the existing single carrier is met, so that the compatibility with the existing LTE system can be well ensured;
B. when a user terminal supports multiple carriers, if the user terminal supports simultaneous receiving and sending of data in uplink and downlink subframes, that is, the user terminal supports dual-channel transmission, the same subframe of the multiple carriers is respectively set as an uplink subframe and/or a downlink subframe in two-dimensional configuration, that is, uplink and/or downlink resources are allocated on the same subframe of the multiple carriers; if the same sub-frame of different carriers is set as the uplink or downlink sub-frame, the service data can be transmitted at the same time in the same sub-frame of a plurality of carriers, thereby improving the transmission efficiency; meanwhile, if the same sub-frame of different carriers is set as uplink and downlink respectively, the user terminal can send and receive service data on the sub-frame at the same time; as shown in fig. 4, when the dotted line indicates that the user supports dual channels, the service data is simultaneously transmitted and received on the same subframe, so that dual-channel transmission is implemented, and the specific configuration is similar to that of the above a, which is not described herein again; meanwhile, the uplink and downlink frame structure of each carrier meets the frame structure of the existing single carrier data transmission;
3) if the user terminal capability information contains the sending power information of the user terminal, namely the maximum uplink carrier number which can be supported by the user terminal in the same subframe, if the sending power of the user terminal exceeds the sending power allowed by the cell where the user terminal is located, namely the sending power is limited, in the two-dimensional configuration, the number of used carriers is reduced in the same subframe on a frequency domain or the subframe in a single carrier is set as an uplink subframe, namely the single carrier is used for data transmission; or on one or more carriers in the time domain, setting a plurality of adjacent uplink subframes for sending uplink service data; it is noted that both settings may exist simultaneously; when subsequent data is transmitted, uplink data can be transmitted through more uplink subframes, so that the transmission power is indirectly reduced, and the compatibility with the existing LTE system is improved;
in addition, on the basis of setting a new frame structure configuration relationship based on the user capability information, setting of the frame structure configuration relationship according to the data volume and the delay information of the service data to be transmitted of the user terminal can be considered; for example, when the delay of the user terminal transmitting the service data is limited, the number of used carriers is increased in the same subframe during two-dimensional configuration, or a subframe adjacent to an uplink subframe for transmitting the uplink service data is set as an uplink subframe, and a subframe adjacent to a downlink subframe for receiving the downlink service data is set as a downlink subframe; during subsequent data transmission, if the time delay is limited, the transmitted uplink data or the received downlink data are distributed to uplink subframes or downlink subframes adjacent to the carrier of the transmitted data and other carriers for transmission or reception;
certainly, in specific implementation, after the capability information of the user terminal is obtained, other factors, such as adjacent channel interference, multi-system coexistence and the like, need to be considered; that is, when configuring uplink and downlink resources, if there are other carriers or other system carriers on both sides of the allocated carrier, the uplink and downlink configuration of the adjacent frequency carrier needs to be considered, so as to avoid interference and interfered: for example, the subframe should be allocated as downlink according to the ue capability information, but if the carrier of the frequency adjacent or the carrier of another frequency adjacent system is uplink, the interference and interfered effect caused by the carrier can be considered during allocation.
In addition, it should be noted that, when the two-dimensional frame structure configuration relationship is set, if the user equipment does not support dual-channel transmission, when the downlink resource is converted into the uplink resource, a special subframe is configured between the downlink subframe and the uplink subframe; the special subframe in a single carrier can be set as an uplink subframe or a downlink subframe according to the data transmission direction; if the same sub-frame on the multi-carrier is a special sub-frame, DwPTS (downlink pilot time slot) and UpPTS (uplink pilot time slot) of the special sub-frame can be configured on different carriers, and the conversion times are reduced as much as possible within the acceptable time delay range; it is particularly noted that different special subframe configurations can be adopted for a plurality of special subframes on the same user equipment multicarrier (i.e. the length of DwPTS, GP, and UpPTS can be different; different selections can be made according to different situations in specific implementation, and further description is omitted here.
Step 103: and sending an indication signaling to the user terminal to inform the user terminal to adopt the new frame structure configuration relationship to send and receive the service data.
Specifically, when the indication signaling is sent to the user terminal, the indication signaling is mainly sent to the user terminal through a high-level signaling, a broadcast message or a downlink control signaling, but is not limited to this; in addition, for the condition that the capability of the user terminal and the service to be transmitted do not change in a short period, the new frame structure configuration relationship can be periodically set and then notified to the user terminal, so that the signaling interaction can be effectively reduced, and the system resources are saved; wherein, the indication signaling at least comprises a carrier number and a subframe number, that is, the user terminal is informed to send or receive service data on the carrier and the subframe indicated by the carrier number and the subframe number; of course, other contents may also be included in the indication signaling, which is not described herein again;
when the frame structure configuration relation during the service data transmission is determined with the user terminal, the subsequent user terminal transmits and receives the service data by using the resources distributed and scheduled on the set subframe; for example, the frame structure configuration relationship set in the above-mentioned mode a is used to allocate and schedule resources for the user terminal, so that the user terminal can continuously transmit and receive service data on the set subframe; for another example, the frame structure configuration relationship set in the above B mode is used to allocate and schedule resources for the user terminal, and the user terminal can implement dual-channel transmission of service data on the set subframe.
It can be seen that, by adopting the method of the embodiment of the present invention, based on the capability of the user terminal, a two-dimensional uplink and downlink frame structure configuration relationship is established in the frequency domain and the time domain, and is notified to the user terminal, so that the base station and the user equipment transmit and receive service data on the time-frequency resources allocated and scheduled based on the two-dimensional frame structure configuration relationship, thereby ensuring the compatibility with the existing LTE system in the aspect of multi-carrier service data transmission, and greatly improving the flexibility of the TDD mode in the multi-carrier system; in addition, the uplink and downlink frame structure configuration relationship is established by utilizing the capability of supporting the service, the data volume, the transmitting power, the time delay and the like of the multi-carrier system by the user terminal, and the service data is transmitted and received according to the uplink and downlink frame structure configuration relationship, so that the multi-aspect requirements of the LTE multi-carrier system can be well supported.
