The preferred embodiments of the present invention are described in conjunction with the accompanying drawings, and the preferred embodiments of the present invention are intended to illustrate and explain the invention, and not to limit the invention, and The embodiments and the features in the embodiments can be combined with each other.

As shown in FIG. 2, a schematic flowchart of an implementation process of a transmission resource allocation method according to an embodiment of the present invention includes the following steps:

5201, at the scheduling moment, the base station determines whether the transmission direction of the information transmitted on the first carrier and the second carrier scheduled by the terminal is opposite on the base station side, if yes, step S202 is performed, otherwise, step S205 is performed;

It should be noted that, in the embodiment of the present invention, for convenience of description, a carrier that is simultaneously scheduled by a base station and whose transmission information direction is opposite is distinguished by a first carrier and a second carrier. Generally, the first carrier is used for A primary carrier carrying information of high importance, and a second carrier is a secondary carrier carrying information of lower importance. It should be understood that the base station can simultaneously schedule N carriers (N is greater than or equal to 2) for the terminal.

5202, the base station determines whether the terminal supports the opposite direction information transmission on the two carriers simultaneously, if yes, step S205 is performed, otherwise, step S203 is performed;

S203. The base station determines a time domain resource occupied by information carried on the first carrier of the current subframe.

S204: Determine, in the current subframe, that the time domain resource occupied by the information carried by the first carrier and the time domain resource is the second carrier available time domain resource;

It should be understood that the frequency domain resources occupied by the first carrier and the second carrier are different, so that when the time domain resources occupied by the first carrier and the second carrier are different, the information transmitted on the first carrier and the second carrier occupy different The location of the time-frequency resource avoids mutual interference when transmitting information of the first carrier and the second carrier.

5205, normal scheduling.

Specifically, in a specific implementation, after determining that the second carrier can use the time domain resource, the base station may determine, according to the type of information carried on the second carrier, a time-frequency resource location occupied by the information carried on the second carrier. The type of information carried on the second carrier may include, but is not limited to, physical downlink shared data channel (PDSCH) information, downlink acknowledgement signaling (ACK) / non-acknowledgment signaling (NACK) information, and downlink channel shield indication (CQI). Downlink control information such as information, physical uplink shared data channel (PUSCH) information, physical uplink control channel (PUCCH), uplink (ACK/NACK) information fed back by the terminal, or uplink (CQI) information fed back by the terminal.

In order to better understand the implementation process of the embodiment of the present invention, the following is an example in which the base station simultaneously schedules two carriers for the terminal at the current time, and the transmission directions on the two carriers are opposite. For convenience of description, the first carrier is used as the first carrier. The primary carrier and the second carrier are secondary carriers, and the corresponding time-frequency resource location determining method is respectively described for the type of information transmitted on the secondary carrier.

1. The secondary carrier carries PDSCH information or downlink ACK/NACK information or downlink CQI information. As shown in FIG. 3a, it is a schematic diagram of a transmission direction of information carried by a base station for a primary carrier and a secondary carrier scheduled by a terminal, and the transmission direction of the fourth subframe of each 5 ms subframe of the primary carrier and the secondary carrier of FIG. 3a is different. The transmission direction of the information carried on the primary carrier is uplink, and the transmission direction of the information carried on the secondary carrier is downlink, and the terminal does not support simultaneous transmission of information in the opposite direction on the primary and secondary carriers. In the embodiment of the present invention, the base station determines the time domain resource of the secondary carrier and the time-frequency resource location occupied by the information carried on the secondary carrier according to the following steps:

Step 1: At the scheduling time (time of subframe 4), the base station determines whether the information carried by the primary and secondary carriers scheduled by the terminal is opposite in the transmission direction of the base station side. If yes, step 2 is performed, otherwise, the normal scheduling is performed.

Step 2: The base station determines whether the terminal supports the simultaneous transmission of the opposite direction information on the primary and secondary carriers scheduled for it, and if yes, performs normal scheduling, otherwise, step 3 is performed;

Step 3: The base station determines that the primary carrier on the subframe 4 carries uplink control information (which may be PUCCH or uplink CQI or uplink ACK/NACK, etc.) occupied by the time domain resource;

In a specific implementation, after determining the time domain resource occupied by the primary carrier, the time-frequency resource location occupied by the primary carrier, that is, the Orthogonal Frequency Division Multiplexing (OFDM) symbol position can be determined; for example, as shown in the figure As shown in 3b, the base station determines that the primary carrier occupies the first two OFDM symbols of subframe 4 (OFDM symbol number 1-2);

Step 4: The base station determines available time domain resources of the secondary carrier.

Specifically, since the available frequency domain resources on the secondary carrier are determined, after determining the available time domain resources, the OFDM symbol positions available for the secondary carrier can be determined. As shown in FIG. 3b, the base station determines the available OFDM symbols of the secondary carrier. The location includes the last 12 OFDM symbols available (OFDM symbol number 3-14); for the primary and secondary carriers, when the occupied time domain resources are different, the information is transmitted without interference at the occupied OFDM symbol positions. .

Step 5: The base station determines, according to the type of information transmitted on the secondary carrier, the location of the time-frequency resource occupied by the information carried on the secondary carrier at the time of the subframe 4.

Specifically, the time domain resource occupied by the downlink control information is determined from the available time domain resources on the secondary carrier, and the time-frequency resource location occupied by the downlink control information (specifically, the OFDM symbol location) is obtained; and the scheduling moment before the current scheduling moment The PDCCH indicates the time-frequency resource location information occupied by the downlink control information; or, when the time domain resource occupied by the PDCCH information of the secondary carrier does not conflict with the time domain resource occupied by the information carried on the primary carrier at the current scheduling time, The time-frequency resource location information occupied by the downlink control information is indicated in the PDCCH of the current scheduling moment.

For example, if the PDSCH information is carried on the secondary carrier, the maximum schedulable symbol resource is 3-14 (OFDM symbol number 3-14) OFDM symbol, and the OFDM position information occupied by the downlink PDSCH information of the subframe 4 may be in the current subframe. The PDCCH information of the previous downlink subframe indicates that, for example, the resource start location information of the downlink PDSCH information of the current subframe is indicated in the PDCCH information of the downlink subframe before the current subframe, and if the PDCCH location of the secondary carrier of the current subframe can be If the transmission is performed (for example, at the time of subframe 4, the OFDM symbol position occupied by the PDCCH information on the secondary carrier does not conflict with the OFDM symbol position occupied by the information carried on the primary carrier (in this example, Occupying 1-2 OFDM symbols)), may also be indicated in the PDCCH of the current subframe; in particular, if the base station determines that the secondary carrier available OFDM symbol position is in the time domain (ie, the time domain resource available for the secondary carrier) is divided into two For a discontinuous region, the OFDM symbol position occupied by the PDSCH information may be determined in the OFDM symbol position included in any region, or the OFDM symbol position occupied by the PDSCH information may be determined in the OFDM symbol positions included in the two regions, respectively. When determining the OFDM symbol position occupied by the PDSCH information in the OFDM symbol positions included in the two regions, the PDCCH symbol positions occupied by the PDSCH information in the two regions of the current subframe may be respectively indicated in the PDCCH of the previous subframe, for example, The PDCCHs of the previous subframes respectively indicate resource start location information of the PDSCH information in the two regions of the current subframe. Preferably, in order to save transmission resources, the base station may also indicate that the PDSCH information is at the current scheduling moment in the PDCCH of the previous subframe. Unoccupied resource location information.

If the secondary carrier carries downlink ACK/NACK or downlink CQ I information, downlink ACK/NACK or downlink

The CQI information is to be limited to the 3-140 FDM symbol. Correspondingly, the OFDM symbol position indication information occupied by the downlink ACK/NACK or the downlink CQI information may be carried in the downlink subframe PDCCH information before the current subframe, and if If the PDCCH position of the secondary subframe of the present subframe can be transmitted, it may be indicated in the PDCCH of the current subframe. In particular, if the base station determines that the secondary carrier available OFDM symbol position is divided into two discontinuous regions in the time domain (ie, the time domain resource available for the secondary carrier), the ACK/NACK information or the CQI may be determined from any region. Information, the OFDM symbol position occupied by the ACK/NACK information or the CQI information may also be determined in two areas, respectively. If the OFDM/NACK information or the OFDM symbol position occupied by the CQI information is determined in two areas, the base station needs to respectively indicate the OFDM/NACK information or the OFDM symbol position information occupied by the CQI information in the two areas in the PDCCH of the previous subframe. Preferably, in order to save transmission resources, the base station may also indicate ACK/NACK information in the previous subframe or OFDM symbol position information that the CQI information is not occupied in the current subframe.

2. The secondary carrier carries PUSCH information or PUCCH or uplink ACK/NACK information or uplink CQI information.

As shown in FIG. 4a, it is a schematic diagram of a transmission direction of information carried on a primary carrier and a secondary carrier scheduled by a base station, and is performed on a fourth subframe of each 5 ms subframe of the primary carrier and the secondary carrier of FIG. 4a. The transmission direction is different, the transmission direction of the information carried on the primary carrier is downlink, and the transmission direction of the information carried on the secondary carrier is uplink, and the terminal does not support simultaneous transmission of information in the opposite direction on the primary and secondary carriers. In the embodiment of the present invention, the base station determines the available OFDM symbol position of the secondary carrier and the time-frequency resource location occupied by the information carried on the secondary carrier according to the following steps: Step 1: The base station determines that the terminal is at the scheduling time (subframe 4) Whether the information carried by the scheduled primary and secondary carriers is opposite in the transmission direction of the base station side. If yes, perform step 2, otherwise, perform normal scheduling.

Step 3: The base station determines that the primary carrier on the subframe 4 carries the time domain resource occupied by the downlink control information.

In a specific implementation, after determining the time domain resource occupied by the primary carrier, the time and frequency occupied by the primary carrier can be determined. The source location, that is, the OFDM symbol position; for example, the base station determines that the downlink control information (which may be PDCCH or downlink CQI or downlink ACK/NACK, etc.) occupies two OFDM symbols; as shown in FIG. 4b and FIG. 4c, respectively At the time of frame 4, a schematic diagram of the occupied OFDM symbol position of the downlink control information carried on the primary carrier, where, in FIG. 4b, the downlink control information carried by the primary carrier (using PDCCH information as an example) occupies 1-20 FDM symbols, in FIG. 4c, The downlink control information carried by the carrier (taking CQI information as an example) occupies 3-40 FDM symbols.

Step 4: The base station determines available time domain resources of the secondary carrier at the time of subframe 4;

Specifically, since the available frequency domain resources on the secondary carrier are determined, after determining the available time domain resources, the OFDM symbol positions available for the secondary carrier can be determined, as shown in FIG. 4b, if the primary carrier occupies 1-2 OFDM. The symbol determines that the secondary carrier available OFDM symbol position includes 3-14 OFDM symbols (the information carried on the secondary carrier is exemplified by the PUSCH); as shown in FIG. 4c, if the primary carrier occupies 3-4 OFDM symbols, it is determined that the secondary carrier is available. The OFDM symbol positions include 1-2 OFDM symbols and 5-14 OFDM symbols (the information carried on the secondary carrier is exemplified by PUSCH).

Specifically, the time domain resource occupied by the uplink control information is determined from the available time domain resources on the secondary carrier, and the time-frequency resource location occupied by the uplink control information (specifically, the OFDM symbol location) is obtained; and the scheduling moment before the current scheduling moment The PDCCH indicates time-frequency resource location information occupied by the uplink control information.

Taking the PUSCH information on the secondary carrier as an example, the maximum schedulable symbol resource is an OFDM symbol position other than the OFDM symbol occupied by the primary carrier (including 3-14 OFDM symbols in FIG. 4b, and 1-2 OFDM symbols in FIG. 4c). And 5-14 OFDM symbols), the OFDM symbol position information (which may be PUSCH information resource start position information) occupied by the PUSCH information may be indicated in the PDCCH information of the downlink subframe before the current subframe. In particular, if the base station determines that the secondary carrier available OFDM symbol position is divided into two discontinuous regions in the time domain (ie, the time domain resource available for the secondary carrier) (as shown in FIG. 4c), it may be in any region. Determining the OFDM symbol position occupied by the PUSCH information on the included OFDM symbol position (1-20 FDM symbol or 5-140 FDM symbol) may also be determined in the OFDM symbols (1-20 FDM symbols or 5-140 FDM symbols) included in the two regions, respectively. The OFDM symbol position occupied by the PUSCH information. If the OFDM symbols occupied by the PUSCH information are respectively determined in the OFDM symbols included in the two regions, the base station needs to indicate the OFDM symbol position information occupied by the PUSCH information in the two regions in the PDCCH of the previous subframe (which may be a PUSCH information resource). Preferably, in order to save transmission resources, the base station may also indicate OFDM symbol position information that the PUSCH information is not occupied at the current scheduling time in the PDCCH of the previous subframe.

Taking the PUCCH or the uplink ACK/NACK or the uplink CQ I information on the secondary carrier as an example, the maximum schedulable symbol resource is an OFDM symbol position other than the OFDM symbol occupied by the primary carrier (including 3-14 in FIG. 4b).

OFDM symbol, including 1-2 OFDM symbols and 5-14 OFDM symbols in FIG. 4c, correspondingly, OFDM symbol position indication information occupied by PUCCH or uplink ACK/NACK or uplink CQI information may be carried in this subframe The previous downlink subframe is indicated in the PDCCH information. In particular, if the base station determines that the secondary carrier available OFDM symbol position is divided into two discontinuous regions in the time domain (ie, the time domain resource available for the secondary carrier), the PUCCH may be determined in the OFDM symbol position included in any region. The information or the OFDM symbol position occupied by the uplink ACK/NACK information or the uplink CQI information may also determine the OFDM symbol position occupied by the PUCCH information or the uplink ACK/NACK information or the uplink CQI information in the OFDM symbol positions included in the two regions, respectively; When determining PUCCH information or uplink ACK/NACK information or uplink CQI information in the OFDM symbol positions included in the two regions, the base station needs to respectively indicate PUCCH information or uplink ACK/NACK information or uplink CQI information in the PDCCH of the previous subframe. OFDM symbol position information occupied by the two regions; Preferably, in order to save transmission resources, the base station may also indicate PUCCH information or ACK/NACK information or OFDM symbol position information of the CQI information not occupied in the current subframe in the PDCCH of the previous subframe. .
