Description

Data transmission method and device in the TDD protection frequency band of the Chinese-language TDD protection band This application claims to be submitted to the Chinese Patent Office on November 23, 2012, the application number is 201210484481.9, and the invention is entitled "Data transmission method and device in the time division duplex TDD protection band" The priority of the Chinese Patent Application, the entire contents of which is incorporated herein by reference. Technical field

The present invention relates to the field of wireless communications, and in particular, to a data transmission method and apparatus in a time division duplex protection band. Background technique

When different time division duplex (TDD) uplink and downlink configurations are configured on two adjacent operating bands, cross interference between uplink and downlink may occur, as shown in Figure 1. The interference between the uplink and the downlink will seriously affect the normal communication. To avoid this interference, the guard band needs to be reserved between the two working bands. The guard band may be attributed to the operator A or the operator B separately, or partially belong to the operator. A. Partially attributed to Carrier B. No data transmission is currently taking place within the guard band.

In a Long Term Evolution (LTE) system, the length of one radio frame is 10 ms, and the length of one subframe is 1 ms, that is, one radio frame contains 10 subframes. For time division (TD) systems, seven TDD uplink and downlink configurations are currently defined in units of one radio frame. As shown in Table 1, D represents a downlink subframe, U represents an uplink subframe, and S represents a special subframe in the TDD system. The special subframe includes a Downlink Pilot Time Slot (DwPTS) and a guard interval. (Guard Period, GP) and Uplink Pilot Time Slot (UpPTS), where DwPTS is used to transmit downlink primary synchronization signals and common downlink service data, and GP is protection interval, generally according to downlink to uplink. The switching time, the uplink to downlink switching time, and the transmission delay associated with the cell radius are defined to avoid overlapping interference between the uplink and the downlink on the same carrier, and the UpPTS is used to transmit the uplink random access signal and the uplink. Probe signal.

Currently, 10 special subframe configurations are defined for different application scenarios, as shown in Table 2, where ^Ts is the system sampling time interval, which is defined based on 1 subframe corresponding to 30720 ^Ts . The subframe structure of different special subframe configurations is shown in Figure 2a and Figure 2b. When the downlink uses a cyclic prefix (CP) (as shown in Figure 2a), a special subframe contains 14 symbols, and the downlink subframe. When using an extended CP (shown in Figure 2b;), a special sub-frame contains 12 symbols.

In order to reduce the system overhead, a new carrier type (NGT) is defined in LTE Release 11 (Rel-11), and the traditional Physical Downlink Control Channel (PDCCH) is not transmitted in the carrier ( That is, legacy PDCCH), which can transmit an Enhanced Physical Downlink Control CHannel (E-PDCCH). The data transmission on this carrier is based on a UE-specific Reference Signal (URS). The Cell-specific Reference Signal (CRS) is transmitted only on antenna port 0 in a period of 5 ms, and is mainly used for tracking.

In summary, since the TDD guard band and the band adjacent to the TDD guard band may belong to different operators, the base station in the TDD guard band cannot obtain the TDD uplink and downlink configuration information used by the adjacent band, and is directly used in the guard band. In any of the TDD uplink and downlink configurations, there may be an uplink/downlink overlap with the adjacent frequency band. As shown in FIG. 1, the subframes in the dotted line frame have an uplink/downlink overlap. Therefore, a specific transmission subframe structure needs to be adopted in the TDD protection band, and the overlap between the uplink subframe and the downlink subframe does not exist in the transmission subframe used in the protection band and the existing multiple TDD uplink and downlink configurations. Therefore, on the basis of avoiding mutual interference between the uplink/downlink subframes in the TDD guard band and the uplink/downlink subframes of other operators in the adjacent frequency band, data transmission in the guard band is realized, and spectrum utilization is improved.

A frame or a regular downlink subframe or an uplink subframe, a ninth subframe, and a 10th subframe are regular downlink subframes or blank subframes. The vacant sub-frame is a sub-frame that does not transmit any data, and the normal downlink sub-frame is a downlink sub-frame that performs downlink transmission on all orthogonal frequency division multiple access (OFDM) symbols in the sub-frame, and the truncated downlink sub-frame For a downlink subframe that performs downlink transmission only on the first M OFDM symbols in the subframe, M is an integer not less than one. Preferably, in order to avoid interference between the truncated downlink subframe and the special subframe on the adjacent frequency band of the TDD guard band, the value of M is 3, and of course, other M value definition methods are not excluded, for example, if the terminal can Obtaining the TDD special subframe configuration used by the pre-frequency carrier can be comprehensively considered according to the TDD special subframe configuration used by the pre-frequency carrier, the TDD protection band, and the TDD special subframe configuration of the carrier pre-frequency. The M value is determined. For example, it is determined that the minimum number of symbols included in the DwPTS in the TDD special subframe configuration used by the two operators is an M value.

Preferably, if the second subframe is a special subframe, the third subframe is an uplink subframe, otherwise the third subframe is a blank subframe; if the seventh subframe is an extended downlink a sub-frame, the eighth sub-frame is a blank sub-frame; if the seventh sub-frame is a normal downlink sub-frame, the eighth sub-frame is a normal downlink sub-frame; if the seventh sub-frame is special a sub-frame, the eighth sub-frame is a blank sub-frame or an uplink sub-frame; if the eighth sub-frame is a normal downlink sub-frame, the ninth sub-frame and the tenth sub-frame are a regular downlink sub-frame Frame, otherwise, the ninth subframe and the tenth subframe are null subframes.

Specifically, in a radio frame, the radio frame includes 10 subframes, and each subframe is from

0 starts the sequence number, and the transmission subframe structure is specifically one of the following structures:

The first structure: subframe 0 and subframe 5 are regular downlink subframes, and subframe 1 and subframe 6 are truncated a downlink subframe, and the remaining subframes are empty subframes;

The second structure: subframe 0 and subframe 5 are regular downlink subframes, subframe 1 is a special subframe, subframe 2 is an uplink subframe, subframe 6 is a truncated downlink subframe, and the remaining subframes are empty subframes. ;

The third structure: subframe 0 and subframe 5 are regular downlink subframes, subframe 1 and subframe 6 are special subframes, subframe 2 is an uplink subframe, and the remaining subframes are empty subframes;

The fourth structure: subframe 0 and subframe 5 are regular downlink subframes, subframe 1 and subframe 6 are special subframes, subframe 2 and subframe 7 are uplink subframes, and the remaining subframes are empty subframes;

The fifth structure: subframe 0, subframe 5, subframe 6, subframe 7, subframe 8 and subframe 9 are regular downlink subframes, subframe 1 is a special subframe, subframe 2 is an uplink subframe, and the rest The subframe is a null subframe.

For the above five structures, see Table 3 below, where D represents a regular downlink subframe, D1 represents a truncated downlink subframe, S represents a special subframe, U represents an uplink subframe, and X represents a null subframe.

table 3

The first type of transmission subframe structure is the most conservative structure. In any scenario, the downlink subframes in the TDD guard band do not overlap with the uplink subframes in the adjacent frequency bands of other carriers.

The foregoing second and third transmission subframe structures are applicable to a scenario in which a guard band is not significantly different from other operators in a transmission band of an adjacent band, such as a non-multi-TA scenario, and a special use in a conservatively configured TDD guard band. On the basis of the subframe (for example, using special subframe configuration 0), the overlapping of the downlink subframe in the TDD guard band with the uplink subframe of other operators in the adjacent frequency band and the uplink subframe in the TDD guard band can be avoided. The overlap with the downlink subframes of other carriers in the adjacent frequency band; in addition, when other operators use the TDD uplink and downlink configuration of the downlink-uplink switching point period of 10 ms in the adjacent frequency band, the TDD protection frequency band is in the second half of the frame. The UpPTS in the special subframe overlaps with the downlink subframes of other operators in the adjacent frequency band, but the overlapping symbols are less, only one symbol. The fourth transmission subframe structure described above is applicable to a scenario in which the TDD uplink and downlink configuration of the downlink-uplink switching point period of the 5ms is used by other carriers in the adjacent frequency band.

The foregoing fifth seed frame structure is applicable to a scenario in which the TDD uplink and downlink configuration of the downlink-uplink switching point period of the 10ms is used by other carriers in the adjacent frequency band.

Specifically, the special subframe in the foregoing transmission subframe structure may adopt the TDD special subframe configuration 0 defined in the LTE system protocol.

The terminal does not perform a measurement process in the vacant subframe in the above-described transmission subframe structure, and the measurement process includes at least a measurement and reporting process related to Radio Resource Management (RRM).

The UE does not blindly detect the PDCCH corresponding to the PUSCH in the subframe in which the null subframe is scheduled, and includes a PDCCH indicating uplink SPS resource activation/release and a PDCCH carrying uplink scheduling signaling (UL grant); and a subframe scheduled by the null subframe. In the frame, there is no data transmission, including uplink and downlink data, that is, no data is received, and no data is sent.

In step 30, the terminal determines the structure of the transmission subframe used in the TDD guard band, and the specific implementation may adopt one of the following six methods:

First, the terminal receives configuration information sent by the network side by using system information or high layer signaling or physical downlink control channel (PDCCH) signaling, where the configuration information indicates one of a predefined TDD uplink and downlink configuration applied to the TDD protection band. The TDD uplink and downlink configuration, and determining that the subframe structure in one radio frame defined by the TDD uplink and downlink configuration is a transmission subframe structure used on the TDD guard band;

The subframe structure in a radio frame defined by the TDD uplink and downlink configuration is a transmission subframe structure used on the TDD guard band, that is, the subframe structure in one radio frame defined by the TDD uplink and downlink configuration satisfies the structure of the foregoing transmission subframe. Conditions, such as the five structures in Table 3, can be pre-defined as five TDD uplink and downlink configurations applied to the TDD protection band.

Second, the terminal determines a TDD uplink and downlink configuration applied to the TDD protection band according to a pre-arrangement with the network side, and determines a subframe structure in a radio frame defined by the TDD uplink and downlink configuration as the transmission sub Frame structure; Here, the subframe structure in a radio frame defined by the TDD uplink and downlink configuration is a transmission subframe structure used on the TDD guard band, that is, the subframe structure in one radio frame defined by the TDD uplink and downlink configuration satisfies the above Conditions for transmitting sub-frame structures, such as the five in Table 3. The structure can be pre-defined as five TDD uplink and downlink configurations applied to the TDD protection band.

Third, the terminal receives configuration information sent by the network side by using system information or higher layer signaling or PDCCH signaling, where the configuration information indicates a null subframe in one radio frame; and a sub-frame in a radio frame defined by the specific TDD uplink and downlink configuration A subframe in the frame structure that is the same as the subframe number indicated by the configuration information is used as a vacant subframe, and determining a subframe structure including a vacant subframe in a radio frame defined by the specific TDD uplink and downlink configuration is used on the TDD guard band. Transmission sub-frame structure; Here, the specific TDD uplink and downlink configuration is one of a plurality of TDD uplink and downlink configurations defined in the LTE system protocol, that is, one of the seven TDD uplink and downlink configurations defined in the existing system, such as Table 1 shows. For example, when the specific TDD uplink and downlink configuration is the TDD uplink and downlink configuration 2 defined in Table 1, the null subframe indicated by the configuration information received by the terminal includes subframe 3, subframe 4, subframe 7, subframe 8, and sub-frame. Frame 9, then, after the terminal uses subframe 3, subframe 4, subframe 7, subframe 8, and subframe 9 in the TDD uplink and downlink configuration 2 as a null subframe, the TDD uplink and downlink configuration 2 includes a sub-frame of the null subframe. The frame structure is the transmission subframe structure used on the TDD guard band, and the transmission subframe structure is the third structure in Table 3.

The subframe structure in a radio frame defined by a TDD uplink and downlink configuration is the specific transmission direction of each subframe in a radio frame corresponding to the TDD uplink and downlink configuration.

Fourth, the terminal receives configuration information sent by the network side by using system information or high layer signaling or PDCCH signaling, where the configuration information indicates available subframes in one radio frame; and divides one radio frame defined by the specific TDD uplink and downlink configuration The subframes other than the subframes with the same subframe number indicated by the configuration information are used as the vacant subframes, and the subframe structure including the vacant subframes in one radio frame defined by the specific TDD uplink and downlink configuration is determined to be used on the TDD guard band. Transmission sub-frame structure; Here, the specific TDD uplink and downlink configuration is one of a plurality of TDD uplink and downlink configurations defined in the LTE system protocol, that is, one of the seven TDD uplink and downlink configurations defined in the existing system, As shown in Table 1. For example, when the specific TDD uplink and downlink configuration is the TDD uplink and downlink configuration 2 defined in Table 1, the available subframes indicated by the configuration information received by the terminal include subframe 0, subframe 1, subframe 2, subframe 5, and sub Frame 6, then, the terminal will be in the TDD uplink and downlink configuration 2 except for subframe 0, subframe 1, subframe 2, subframe 5, and subframe 6 (ie, subframe 3, subframe 4, subframe 7) After the sub-frame 8 and the sub-frame 9 are used as the vacant sub-frame, the sub-frame structure including the vacant sub-frame in the TDD uplink and downlink configuration 2 is used on the TDD guard band. The transmission subframe structure, which is the third structure in Table 3.

Fifth, the terminal determines, according to a pre-arrangement with the network side, a null subframe in a radio frame, and uses a subframe with the same subframe number as the pre-agreed subframe number in the subframe structure in one radio frame defined by the specific TDD uplink and downlink configuration. The vacant sub-frame determines that the subframe structure including the vacant subframe in one radio frame defined by the specific TDD uplink and downlink configuration is a transmission subframe structure used on the TDD guard band; here, the specific TDD uplink and downlink configuration is in the LTE system protocol. One of the plurality of TDD uplink and downlink configurations defined is one of the seven TDD uplink and downlink configurations defined in the existing system, as shown in Table 1. The difference between this method and the third method is that the null subframe is pre-agreed with the network side, rather than the network side indicating by the configuration information.

Sixth, the terminal determines, according to the pre-arrangement with the network side, the available subframes in one radio frame, and the other subframes defined by the specific TDD uplink and downlink configuration, except for the subframes with the same subframe number as the pre-agreed subframe number. As a vacant subframe, determining a subframe structure including a vacant subframe in a radio frame defined by the specific TDD uplink and downlink configuration is a transmission subframe structure used on a TDD guard band; where, the specific TDD uplink and downlink configuration is an LTE system protocol. One of the multiple TDD uplink and downlink configurations defined in the system is one of the seven TDD uplink and downlink configurations defined in the existing system, as shown in Table 1. The method differs from the fourth method only in that the available subframes are pre-agreed with the network side, and not the network side is indicated by the configuration information.

Specifically, the terminal may determine the specific TDD uplink and downlink configuration according to the notification sent by the network side through the system information or the high layer signaling or the PDCCH signaling; or the terminal determines the specific TDD uplink and downlink configuration according to the pre-arrangement with the network side; or, the terminal Determining the TDD uplink and downlink configuration used by the adjacent frequency band of the TDD protection band as a specific TDD uplink and downlink configuration, the adjacent frequency band and the TDD protection frequency band belong to the same carrier; or the frequency band in which the terminal aggregates with the TDD protection frequency band The TDD uplink and downlink configuration used is determined to be a specific TDD uplink and downlink configuration.

In the step 31, the terminal performs data transmission on the TDD protection band according to the transmission subframe structure and the network side, and specifically includes:

The terminal receives the physical downlink shared signal corresponding to the PDCCH according to the PDCCH carrying the downlink scheduling signaling detected in the regular downlink subframe or the truncated downlink subframe or the special subframe numbered n. Road (PDSCH) information.

That is, the downlink scheduling timing of the TDD guard band is: PDSCH transmission in the downlink subframe numbered n (including the DwPTS part, the normal downlink subframe, and the truncated downlink subframe in the special subframe), detected by the subframe PDCCH scheduling for bearer downlink scheduling grant (DL grant);
