Description

Method and device for configuring signal transmission mode of wireless communication system

The present invention relates to wireless communication technologies, and in particular, to a method and apparatus for configuring a signal transmission mode of a wireless communication system.

Background technique

In a wireless communication system, user equipment (User Equipment, UE) in different wireless environments uses different transmission methods for communication with the base station. For example, when the UE is in the center of the cell, the channel is in a good condition and is suitable for transmission at a higher rate. Therefore, the base station and the UE use a spatial multiplexing (SM) method to transmit and receive signals to improve the transmission rate, and Guarantee transmission reliability. When the UE is at the cell edge, the channel condition is poor, which is suitable for transmission at a lower rate. Therefore, the base station and the UE use a Transmit Diversity (TD) method or a single layer transmission method to transmit and receive signals to ensure transmission. reliability.

a transmission mode for transmitting and receiving signals between the base station and the UE, and the base station sends a dynamic control signaling to the UE to configure a transmission mode to indicate that the base station and the UE transmit and receive signals between the base station and the UE within the current transmission time interval (TTI). The transmission mode corresponding to the transmission mode is adopted. Since each TTI base station sends signaling to configure the transmission mode, the channel load is increased. In order to solve the above problem, in the prior art, the base station configures a transmission mode for the UE by sending semi-static configuration signaling, and uses the transmission mode with the UE in all TTIs before the base station sends the next semi-static configuration signaling. The transmission mode is to send and receive signals. However, when the channel state changes frequently, if the existing method is used to configure the transmission mode for the UE, the base station needs to frequently send the semi-static configuration signaling, so that the channel load increases, and the role of the semi-static configuration signaling is further reduced.

The present invention will be further described in detail with reference to the accompanying drawings, in which FIG. An embodiment. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. FIG. 1 is a flowchart of a method for configuring a signal transmission manner of a wireless communication system according to an embodiment of the present invention. The method shown in this embodiment is an operation flow on the network device side. The network device can be a base station (BS), an access point (AP), a remote radio equipment (RRE), a remote radio head (RRH), and a remote radio unit. (Remote Radio Unit, RRU), relay node, etc. Network design The relationship between the standby and the cell is not limited, and may be one network device corresponding to one or more cells, or one cell corresponding to one or more network devices. The method for configuring a signal transmission mode of a wireless communication system by a network device specifically includes:

Step 11: Determine a first transmission mode corresponding to the first transmission time interval (TTI) set and a second transmission mode corresponding to the second TTI set, where the first transmission mode and the second transmission mode are different.

The first transmission mode and the second transmission mode may be an uplink transmission mode, or the first transmission mode and the second transmission mode may be a downlink transmission mode.

The TTI set of the downlink transmission is a set of TTIs that the network device sends to the UE and the UE receives the signal of the network device. The TTI set of the uplink transmission is a set of TTIs that the UE uses to send signals to the network device and the network device receives the signals of the UE. In this embodiment, the network device may divide the TTI set of the uplink transmission, for example, classify the TTIs with better channels into a set such as the TTI set A, and classify the TTIs with strong interference or poor channel into one set. For example, TTI set B, then configure one transmission mode a for TTI set A, and another transmission mode b for TTI set B, to transmit uplink signals in the transmission mode of transmission mode a in the TTI in TTI set A, in the TTI set. The TTI in B transmits the uplink signal by using the transmission mode in the transmission mode b.

Similarly, the network device may divide the TTI set of the downlink transmission, such as classifying the better TTIs of the channel into a set such as the TTI set C, and classifying the TTIs with strong interference or poor channel into a set such as TTI. Set D, then configure a transmission mode c for the TTI set C, and configure another transmission mode d for the TTI set D, so that the TTI in the TTI set C transmits the downlink signal in the transmission mode in the transmission mode c, in the TTI set D. The TTI transmits the downlink signal by using the transmission mode in the transmission mode d.

There are 10 modes for the transmission mode of the downlink transmission: Mode 1 (Model 10 Mode 10 (Model0), as shown in Table 1. Table 1 Physical downlink control channel downlink control information corresponds to a physical downlink control channel

Mode 9 (Mode 9) DCI format 1A single antenna port or transmit diversity

DCI format 2C Up to 8 layers of transmission or single antenna port Mode 10 (Mode 10) DCI format 1A Single antenna port or transmit diversity

DCI format 2C Up to 8 layers of transmission, supporting Coordinated Multiple Point transmission/reception (CoMP) In Table 1, each transmission mode corresponds to two PDCCHs in the downlink control information (DCI) format. And corresponding to at least one PDSCH transmission mode. In the Long Term Evolution (LTE) system, the DCI is information that is sent by the network device to the UE and is used to schedule the UE to send or receive signals according to the indication of the information. The PDCCH is a general term for the signal that the network device sends the DCI. Different PDSCH transmission methods require different types of DCI information, including modulation coding scheme (Modulation and Coding Scheme, MCS) Information, precoding information, transmission layer number information, etc., and corresponding to different formats of DCI, such as DCI format 1, DCI format 2, etc. shown in Table 1. In this way, according to the environment in which the UE is located, the preferred transmission mode suitable for the environment can be flexibly adopted to ensure the stability and reliability of the transmission. For example, the UE1 is in the cell center, the channel condition is good, and the network device is It can be configured with a transmission mode Mode9 or ModelO to support up to 8 layers of transmission, thus improving transmission efficiency while ensuring reliability. For example, if the UE2 is at the cell edge and the channel conditions are not good, the network device can configure the transmission mode Mode6 for the network, and send the PDSCH to the UE by using the diversity or single-layer closed-loop spatial multiplexing mode to ensure the reliability of the transmission.

When the network device sends the DCI to the UE to schedule the UE to receive the PDSCH, the network device sends the DCI to the UE in the TTI numbered n, and sends the PDSCH corresponding to the TTI in other resources of the TTI. The UE first detects the DCI in the TTI, and detects the PDSCH on the corresponding resource according to the DCI after detecting, so that the data sent by the network device is received. The two DCI formats corresponding to each transmission mode include DCI format 1A, so that the UE can detect some common PDSCH signals. These common PDSCH signals are usually broadcasted to all UEs, that is, the network devices only send once. It is hoped that all UEs can receive these common PDSCH signals, thereby improving transmission efficiency. Since these common PDSCH signals need to be sent to all UEs, the most reliable transmission method such as single antenna port or transmit diversity must be adopted. Therefore, in this paper, the main transmission mode other than the transmission mode corresponding to DCI format 1A is mainly concerned. The transmission mode of the uplink transmission is shown in Table 2.

Table 2

The uplink transmission mode includes two types, where Mode 1 only allows the UE to transmit the PUSCH through a single antenna port, and Mode 2 allows the UE to transmit the PUSCH by using closed-loop spatial multiplexing, thereby obtaining more stable or faster data transmission. During the uplink transmission, the network device sends the DCI to the UE in the TTI with the number n, and the UE first detects the DCI in the TTI, and after detecting the TTI, the TTI is numbered n+4, and the PUSCH is sent on the corresponding resource according to the DCI. . Correspondingly, the network device receives the PUSCH transmitted by the UE according to the DCI in the TTI numbered n+4. In this embodiment, the transmission mode determined by the network device for the TTI set of the uplink transmission may be the transmission mode in Table 2, and the transmission mode determined for the TTI set of the downlink transmission mode may be the transmission mode in Table 1.

Exemplarily, the first TTI set is a TTI set with a higher interference to the UE than a preset value, and the second TTI set is a TTI set with interference to the UE that is lower than the preset value, Determining that the reliability of the first transmission mode is higher than the second transmission mode, and determining that the transmission efficiency of the second transmission mode is higher than the first transmission mode; for example, the first transmission mode may be the transmission mode 1 In any of the-8, the second transmission mode may be the transmission mode 9 or 10. Or,

The first set of TTIs may be a set of TTIs for transmitting a first amount of data, and the second set may be a set of TTIs for transmitting a second amount of data, where the first amount of data is greater than or equal to a threshold value, The second data amount is less than the threshold, and the determined transmission efficiency of the first transmission mode is higher than the second transmission mode, and the determined reliability of the second transmission mode is higher than the first Transfer mode.

Exemplarily, the TTI set that is higher than the preset value of the interference of the UE is a TTI set that sends a downlink signal to a second network device whose transmit power is higher than the first network device, where the interference to the UE is low. The TTI set of the preset value is a TTI set in which the second network device does not send a downlink signal, where the first network device is a network device that sends the semi-static configuration signaling to the UE; The first transmission mode is a transmission mode in which the transmission mode is a single-layer closed-loop spatial multiplexing, and the determined second transmission mode is a transmission mode in which the transmission mode is a transmission of up to 8 layers;

Or the TTI set that is higher than the preset value by the UE is a TTI set of inter-device direct communication D2D between the network devices, and the interference between the UEs is low. The TTI set of the preset value is a non-interactive backhaul information between the network devices or a TTI set that is not D2D; the determined first transmission mode is a transmission mode of single layer transmission or large delay cyclic delay diversity CDD transmission. Mode, or for transmission mode does not support coordinated multipoint transmission/reception The transmission mode of the CoMP, or the transmission mode of the single antenna port, the determined second transmission mode is a spatial multiplexing transmission mode with a transmission mode greater than 1 layer, or a transmission mode supporting a CoMP transmission mode. Or the transmission mode is spatially multiplexed. Assume that the determined first transmission mode and the second transmission mode are downlink transmission modes, and further determines a third transmission mode corresponding to the third TTI set and a fourth transmission mode corresponding to the fourth TTI set, and the determined third transmission The mode and the fourth transmission mode are uplink transmission modes. For downlink transmission, one of the first transmission mode and the second transmission mode includes a spatially multiplexed transmission mode greater than one layer, and the other transmission mode includes a single layer transmission or a transmission mode of a large delay CDD. As shown in Table 1, the spatial multiplexing transmission mode of more than one layer includes any one of Mode 4, Mode 5, Mode 8, Mode 9, and Model O. These transmission modes have high transmission efficiency and can significantly improve system throughput; Layer transmission or large delay CDD transmission modes include Model (single layer transmission), Mode2 (single layer transmit diversity), Mode3 (large delay CDD), Mode6 (single layer spatial multiplexing), or Mode7 (single layer transmission). The transmission mode can better resist the strong interference environment and ensure good transmission reliability. Alternatively, one of the first transmission mode and the second transmission mode is a CoMP-supported transmission mode (ie, ModelO), and the other transmission mode is a CoMP-free transmission mode (ie, other transmission modes other than ModelO); ModelO can support CoMP technology, which has high transmission efficiency and can avoid strong interference through coordination or joint scheduling between network devices. For the uplink transmission, one of the third transmission mode and the fourth transmission mode includes a spatially multiplexed transmission mode, that is, Mode2, and the other transmission mode includes a single antenna port transmission mode, that is, a Model. The specific effect is the same as the downlink transmission, as described below. Step 12: Send, by the semi-static configuration signaling, at least one TTI set information of the first TTI set information and the second TTI set information, and the first transmission mode information, to a user equipment (User Equipment, UE) And the second transmission mode information. Wherein, semi-static signaling example ia Access Control, MAC) letter

It is assumed that a certain TTI set includes a first TTI set and a second TTI set, the first TTI set includes TTIs numbered 3, 8, and the second TTI subset includes a TTI other than the numbers 3 and 8 in one radio frame. Other TTIs, which can send information of the first TTI set and the second TTI set For the UE, the information of the first TTI set (ie, the information of the TTIs numbered 3 and 8) may also be sent only to the UE, and the other TTIs are the second set of TTIs. The first TTI set may be a TTI set of interaction backhaul information between network devices, or a TTI set that can be used for Device to Device (D2D) transmission, or another set of TTIs that may have strong interference. Then the second set of TTIs is a set of other TTIs than the first set of TTIs. The semi-static configuration signaling sent by the network device to the UE may include the TTI set of the uplink transmission or the TTI set of the downlink transmission, or may include the TTI set of the uplink transmission and the TTI set of the downlink transmission. When the semi-static configuration signaling includes the information of the TTI set of the uplink transmission, the semi-static configuration signaling further includes information about the transmission mode corresponding to the TTI set of the uplink transmission determined in step 11. In this way, the UE may use the TTI set corresponding to the TTI in the TTI of the uplink transmission before receiving the next static configuration signaling according to the information of the TTI set and the information of the transmission mode in the semi-static configuration signaling. The transmission mode in the transmission mode uplinks the signal. For example, the semi-static configuration signaling includes information of the TTI set A and the TTI set B, and the network device determines the information of the transmission mode a corresponding to the TTI set A and the transmission mode b corresponding to the TTI set B, and the UE transmits the TTI in the uplink. If it is determined that the TTI of the transmitted signal belongs to the TTI set A or the TTI set B, if the TTI of the transmitted signal belongs to the TTI set A, the signal is transmitted by using the transmission mode in the transmission mode a, and if the TTI of the transmitted signal belongs to the TTI set B, The transmission mode in transmission mode b transmits a signal. When the semi-static configuration signaling includes the information of the TTI set of the downlink transmission, the semi-static configuration signaling further includes information about the transmission mode corresponding to the TTI set of the downlink transmission determined in step 11. In this way, the UE may use the TTI set corresponding to the TTI in the TTI of the downlink transmission before receiving the next static configuration signaling according to the information of the TTI set and the information of the transmission mode in the semi-static configuration signaling. The transmission mode in the transmission mode downlinks the signal. For example, the semi-static configuration signaling includes information of the TTI set C and the TTI set D, and the network device determines the information of the transmission mode c corresponding to the TTI set C and the transmission mode d corresponding to the TTI set D, and the TTI of the downlink transmission of the UE. The TTI of the received signal is determined to belong to the TTI set C or the TTI set D. If the TTI of the received signal belongs to the TTI set C, the signal is received by the transmission mode in the transmission mode c. If the TTI of the received signal belongs to the TTI set D, the TTI is used. The transmission mode in transmission mode d receives the signal. When the semi-static configuration signaling includes a TTI set of the uplink transmission and a TTI set of the downlink transmission For example, the method provided by the embodiment of the present invention further includes: determining a third transmission mode corresponding to the third TTI set and a fourth transmission mode corresponding to the fourth TTI set, the third transmission mode and the fourth transmission The mode is different; the first transmission mode and the second transmission mode are uplink transmission modes, and the third transmission mode and the fourth transmission mode are downlink transmission modes, or the first transmission mode and the second transmission mode are downlink a transmission mode, where the third transmission mode and the fourth transmission mode are uplink transmission modes;

Transmitting, by the semi-static configuration signaling, at least one of the third TTI set information and the fourth TTI set information, and the third transmission mode information and the fourth transmission to the user equipment UE The mode information, the method further includes: transmitting, by the semi-static configuration signaling, at least one of the third TTI set information and the fourth TTI set information, and the third transmission mode information to the UE And the fourth transmission mode information.

In this way, the UE may use the information corresponding to the TTI to which the TTI belongs in the TTI of the uplink transmission before receiving the next static configuration signaling according to the information of the TTI set and the information of the transmission mode in the semi-static configuration signaling. The transmission mode in the transmission mode uplinks the signal. For example, the semi-static configuration signaling includes information of the TTI set A and the TTI set B, and the network device determines the information of the transmission mode a corresponding to the TTI set A and the transmission mode b corresponding to the TTI set B, and the UE transmits the TTI in the uplink. If it is determined that the TTI of the transmitted signal belongs to the TTI set A or the TTI set B, if the TTI of the transmitted signal belongs to the TTI set A, the signal is transmitted by using the transmission mode in the transmission mode a, and if the TTI of the transmitted signal belongs to the TTI set B, The transmission mode in the transmission mode b transmits a signal; in the TTI of the downlink transmission, the signal is downlink-transmitted by using a transmission mode in a transmission mode corresponding to the TTI set to which the TTI belongs. For example, the semi-static configuration signaling includes information of the TTI set C and the TTI set D, and the network device determines the information of the transmission mode c corresponding to the TTI set C and the transmission mode d corresponding to the TTI set D, and the TTI of the downlink transmission of the UE. If it is determined that the TTI of the received signal belongs to the TTI set C or the TTI set D, if the TTI of the received signal belongs to the TTI set C, the signal is received by using the transmission mode in the transmission mode c, and if the TTI of the received signal belongs to the TTI set D, The transmission mode in transmission mode d receives the signal. Further, the third TT set, the fourth TTI set, and the first TTI set and the second TTI set partially overlap. The TTI set transmitted as above and the TTI set of the downlink transmission may also be partially or completely identical. For example, if both the TTI set A and the TTI set D include the TTI numbered 4, the UE uses the transmission mode a if it receives an indication from the network device and transmits a signal in the TTI numbered 4. The next transmission mode transmits a signal; if receiving an indication from the network device and receiving a signal in the TTI numbered 4, the signal is received by the transmission mode in the transmission mode d. In this embodiment, by sending a semi-static configuration signaling to the UE, the UE can be configured with at least two transmission modes, and the TTI sets corresponding to different transmission modes are different, so that the network device can send the TTI to which the TTI belongs to the UE in different TTIs. The signaling of the DCI format corresponding to the corresponding transmission mode is set to schedule the UE to transmit the signal by using the transmission mode corresponding to the signaling. In this way, different transmission modes can be adapted to different interference situations, respectively, thereby ensuring reliable transmission in a disturbance fluctuation environment. And configuring the transmission mode in the interference fluctuation environment by using a semi-static configuration signaling. After the network device sends the TTI set information to the UE and takes effect, the configuration is always used until the next time the new TTI set information is sent to the UE. The information can indicate long-term transmission configuration information to the UE through one information transmission, effectively reducing information overhead, reducing channel load, improving configuration efficiency, and making the role of semi-static configuration signaling more obvious. For example, if the network device configures one of the transmission modes for each UE, the dynamic control signaling (ie, PDCCH) corresponding to the transmission mode is sent only to the UE, and only the transmission mode is used to send data or receive to the UE. Data from the UE, including downlink data (ie, PDSCH) and uplink data (ie, PUSCH). For the UE, since the network device only configures one transmission mode, the network device only sends the DCI of the format corresponding to the transmission mode to the UEs, and the UE only needs to detect the DCI of the formats sent by the network device. For example, if UE3 is configured with Mode 1, UE3 only needs to detect DCI formats 1 and 1A sent by the network device, and does not need to detect DCI in other formats. However, when the fluctuation of the wireless channel becomes severe, as shown in Figure 2 In the heterogeneous network (Hetogeneous Network, HetNet) environment, UE 1 is served by the first network device, UE2 is served by the second network device, and the transmit power of the first network device and the second network device are different, assuming the first The network device is higher than the second network device, and the coverage of the two network devices is different. The coverage of the first network device includes the coverage of the second network device, so that if the first network device sends a downlink signal to the UE1, The downlink signal sent by the second network device to the UE2 causes strong interference; when the first network device does not send the downlink signal, the UE2 does not cause strong interference to the UE2, that is, the UE2 receives the signal sent by the second network device. The interference fluctuates as the first network device transmits a signal. In such a scenario, UE2 is different in interference from the signal transmitted by the first network device at different times, so different times should be applied to different transmission modes. For example, if UE2 is not subjected to strong interference, it is suitable for transmissions of up to 8 layers, so it is suitable for Mode 9 or 10; if UE2 is subjected to strong interference, it is applicable to a single-layer closed-loop spatial multiplexing scheme, that is, Mode 6. If the prior art is used, only one transmission mode is configured at a time, which increases the channel load and the burden on the network device, or the transmission efficiency is not high. If the technical solution provided in this embodiment is adopted, the network device can configure at least two transmission modes for the UE at one time. For any two transmission modes, the network device sends a data signal to the UE or receives the data signal sent by the UE in the first TTI set according to the transmission mode corresponding to the first transmission mode, and uses the second transmission mode in the second TTI set. The transmission mode transmits a data signal to the UE or receives a data signal sent by the UE. With reference to FIG. 2, the first network device sends the PDSCH to the UE1 only in the first TTI set, and causes strong interference to the UE2, and the second network device can use the first transmission mode suitable for high interference (for example, Mode6). Communicating with the UE to transmit DCI to the UE in DCI format 1B, instructing UE2 to receive the PDSCH in a single-layer closed-loop spatial multiplexing transmission manner in the first TTI set; further, the first network device does not transmit the PDSCH in the second TTI set Therefore, the UE2 does not cause strong interference to receive the PDSCH sent by the second network device, and the second network device can communicate with the UE2 by using a second transmission mode (for example, Mode9 or 10) suitable for low interference, thereby adopting the DCI format. The 2C sends a DCI to the UE2, instructing the UE2 to receive the PDSCH in a closed-loop spatial multiplexing transmission manner of up to 8 layers in the first TTI set. Therefore, the technical solution shown in this embodiment has the advantage that the network device configures at least two transmission modes for the UE-time, so that different transmission modes are used to communicate with the UE in different TTIs, so that the signal transmission and the interference environment corresponding to the TTI are transmitted. The matching enhances the reliability of the transmission, and effectively reduces the load generated by the channel configuration mode of the network device, and improves the configuration efficiency of the transmission mode. In this paper, the single layer and the 8 layers are the number of transmission layers, and the number of transmission layers is the number of transmission layers representing the space. The higher the number of layers, the higher the transmission efficiency and the worse the stability; the more the number of transmission layers is usually It is suitable for scenarios with high Signal to Interference plus Noise Ratio (SINR), such as cell center UE. Exemplarily, the intersection between the first TTI set and the second TTI set is 0. The first TTI set transmitted as above does not overlap with the second TTI set, so that it is convenient to keep the complexity of the UE detecting DCI unchanged. As in the downlink of the LTE system, the UE detects the DCI at the TTI numbered n, and also receives the PDSCH in the TTI. Generally, in an LTE system, regardless of the network device configured for the UE In which transmission mode, the UE performs up to 44 DCI detections. The technical solution provided by the embodiment of the present invention is used. Although the UE is configured with multiple transmission modes, for the same TTI, the UE only needs to detect the DCI corresponding to one transmission mode, and does not increase the UE for DCI detection. frequency. That is, the embodiment of the present invention maintains a transmission mode in the same TTI, and the UE still only needs to detect the DCI corresponding to one transmission mode, and the UE is for the same TTI while increasing the transmission mode that the UE can support. There is no need to increase the number of detected DCI formats, and thus there is no increase in the complexity of the UE detecting DCI. Exemplarily, the first TTI set is a TTI set with a higher interference to the UE than a preset value, and the second TTI set is a TTI set with interference to the UE that is lower than the preset value, The determined reliability of the first transmission mode is higher than the second transmission mode, and the determined transmission efficiency of the second transmission mode is higher than the first transmission mode.

Optionally, the TTI set that is higher than the preset value of the interference of the UE is a TTI set that sends a downlink signal to a second network device whose transmit power is higher than the first network device, where the interference to the UE is low. The TTI set of the preset value is a TTI set in which the second network device does not send a downlink signal, where the first network device is a network device that sends the semi-static configuration signaling to the UE; The first transmission mode is a transmission mode in which the transmission mode is a single-layer closed-loop spatial multiplexing, and the determined second transmission mode is a transmission mode in which the transmission mode is a transmission of up to 8 layers.

In the scenario shown in FIG. 3, the UE and the second network device use a certain frequency band for communication, and the first network device and the second network device may also use the frequency band to transmit backhaul information in a wireless manner (ie, between network devices). Interactive information). Therefore, the signal sent by the first network device to the second network device may cause interference to the signal sent by the UE to the second network device. Generally, the rate of transmitting backhaul information between network devices is relatively constant, so the resources used for the interactive backhaul information between the first network device and the second network device are fixed for a certain period of time, for example, in LTE. In the system, one radio frame includes 10 subframes (numbered from 0 to 9 respectively), and one subframe length is a TTI. If the frame numbered 3, 8 is used to transmit the backhaul information in a radio frame, the uplink signal sent by the UE to the second network device in the two frames is strong by the backhaul information sent by the first network device. Interference, while in other areas, it will not be disturbed. With the method provided in the foregoing embodiment, two transmission modes can be configured for the UE. Specifically, ΤΤΙ 3 (ie, ΤΤΙ numbered 3) and ΤΤΙ 8 (ie, ΤΤΙ numbered 8) may be used as a set of ΤΤΙ in the set of uplink transmissions (referred to as a first set of 为 for convenience of description), Put other ΤΤΙ as available Another set of TTIs in the set of TTIs for transmission (referred to as a second set of 为 for ease of description), and determining to use the first transmission mode in the first set (ie, 编号 numbered 3, 8), the first The transmission mode can ensure stable transmission even in the case of strong interference, or can be adapted to be transmitted simultaneously with the wireless backhaul information. It is determined that the second transmission mode is used in the second set, which can bring higher transmission efficiency, so that both of these can be taken into consideration. Different chirp interference conditions are used to use the appropriate transmission mode.

As shown in Figure 4, the D2D scenario indicates that the UE and the UE can communicate directly without going through the network device. In this scenario, the network device may send the D2D information to the UE, and the UE2 may directly send the D2D signal to the UE3, and the D2D signal may cause interference to the uplink signal sent by the UE1 to the network device, which is provided by using the foregoing embodiment. The method, the UE may send the set of D2D signals as a second set of the set of uplink transmissions, and determine a transmission mode configured by the network device in the second set of the second set, and other The first set of ΤΤΙ in the set of uplink transmissions is determined to determine another transmission mode configured by the network device within the ΤΤΙ of the first set to ensure reliable transmission.

Or, exemplarily, the first set of 为 is a set of ΤΤΙ for transmitting a first amount of data, and the second set is a set of 用于 for sending a second amount of data, where the first amount of data is greater than or equal to a threshold value, the second data amount is less than the threshold value, and the determined transmission efficiency of the first transmission mode is higher than the second transmission mode, and the determined reliability of the second transmission mode is higher than The first transmission mode. For a video service scenario, for a typical video data, the change of the video picture is a slow process for a certain video environment. Taking a mobile video as an example, the network device sends the video to the UE. As shown in FIG. 5, the person moves from the lower left corner (left image) to the upper right corner (right image), when the screen is switched to someone in a specific environment. In the middle (as shown in the left figure below), the network device needs to send a larger amount of data to the UE, including data of all video pictures of the entire environment, and is suitable for adopting a transmission mode corresponding to spatial multiplexing. When the environmental data does not change, and only the position of the person changes, it is not necessary to frequently send the entire video picture to the UE, and only the data of the part of the video picture caused by the movement of the right picture relative to the left picture is sent to the left picture. The UE can be. In this case, the amount of data that the network device needs to send to the UE during the mobile process is not large, and the transmission mode such as single-layer closed-loop spatial multiplexing is suitable. When the method shown in the embodiment of the present invention is used, all the 发送 that send a large amount of data (such as the amount of data larger than the preset value) can be regarded as a set of ( (for convenience of description, the ΤΤΙ set is hereinafter referred to as a set of ΤΤΙ Μ) , the amount of data to be sent is small (for example, the number is greater than the preset value) All TTIs of the data volume are regarded as another TTI set (for convenience of description, the TTI set is hereinafter referred to as TTI set N), and the network device determines the transmission mode m of the TTI set M and the transmission mode n of the TTI set N, and passes a semi-static configuration signaling, the information of the at least one TTI set in the TTI set M and the TTI set N and the information of the transmission mode m and the transmission mode n are sent to the UE, and the network device uses the transmission mode in the TTI of the TTI set M The transmission mode under m (such as spatial multiplexing) transmits video data, and the UE uses the transmission mode (such as spatial multiplexing) in the transmission mode m to receive the video data sent by the network device; in the TTI of the TTI set N, the network device uses the transmission mode. The transmission mode under n (such as single-layer closed-loop spatial multiplexing) transmits video data, and the UE receives the video data transmitted by the network device by using a transmission mode under transmission mode n (such as single-layer closed-loop spatial multiplexing). The method for configuring the signal transmission mode of the wireless communication system provided by the embodiment of the present invention is described by taking the video service as an example. The amount of other service data may be different with time or transmitted between the network device and the UE at different times. The examples with different amounts of data are similar, and will not be described here. When the amount of data transmitted between the network device and the UE is different at different times, the method provided by the embodiment of the present invention can also facilitate the transmission of such services. Specifically, when the video picture is completely changed (for example, the screen is switched to the person moving in a new environment), the network device sends the PDSCH to the UE by using the transmission mode corresponding to the high transmission rate by using the foregoing method; and when the video picture part changes, the network device The PDSCH is transmitted to the UE using a transmission mode corresponding to a low transmission rate. Or the network device sends the PDSCH to the UE by using different transmission modes according to the change of the video picture being higher or lower than a certain threshold. Exemplarily, the information of the at least one TTI set includes information of a periodic set of TTIs. For example, in a periodic TTI set, the intervals between TTIs are the same, for example, the TTIs in the TTI set are TTIs numbered 2, 7, 12, 17, 22, 27. The information of the periodic set of 包括 includes a period of the set of periodic ΤΤΙ and an offset of ΤΤΙ of the set of periodic ΤΤΙ. For example, if the network device sends the ΤΤΙ in the ΤΤΙ set to 5 TTIs and the ΤΤΙ offset is 3 ΤΤΙ, the network device sends 5 ΤΤΙ and offset 3 ΤΤΙ to the UE, and the UE can learn ΤΤΙ The collection is ΤΤΙ numbered 3, 8, 13, 18, ... to further perform corresponding transmission processing in the collection according to the transmission mode information.

After the semi-static configuration signaling is sent to the user equipment UE, the method further includes: Sending activation signaling, such as Semi-Static Scheduling (SPS) transmission activation signaling, to the UE, so that after receiving the activation signaling, the UE receives the next semi-static configuration signaling, according to The information of the at least one TTI set, and the first transmission mode information and the second transmission mode information, are transmitted in a corresponding transmission mode in a TTI of the first TTI set and the second TTI set signal.

For example, after the semi-static configuration signaling is sent to the user equipment UE, the network device may send the scheduling signaling to the UE only once, for activating the multi-transmission mode SPS transmission, for example, the UE receives the scheduling signaling and sends the scheduling signaling to the network device. After the acknowledgement (ACK), the network device sends the downlink data to the UE in the first TTI set using the first transmission mode, and uses the second transmission mode to send the downlink data to the UE in the second TTI set. In this way, the UE can be triggered to receive data sent by the network device in multiple TTIs by using only one scheduling, and the transmission modes corresponding to different TTIs are different. For example, the first transmission mode supports a high transmission rate (for example, Mode9), and can be used to transmit data when the video picture is completely changed; the second transmission mode supports a low transmission rate (for example, Mode6), which can be used when transmitting a video picture part change. Data, and save DCI information overhead and resources for sending PDSCH. When it is not necessary to transmit a video signal (for example, the video signal transmission is completed), the network device can retransmit the deactivation signaling to the UE to cancel the multi-transmission mode SPS transmission.

For the Hybrid Automatic Repeat Request (HQQ) scenario, the method provided by the embodiment of the present invention further includes:

Receiving, by the UE, data that is initially transmitted by using the transmission mode in the first transmission mode in the first TTI set, and performing decoding; if the decoding fails, sending, by using, the first transmission mode to the UE a first indication of the retransmission of data by the transmission mode;

Or, it also includes:

In case the decoding fails, the transmitting party in the second transmission mode is sent to the UE. a second indication of retransmission of data;

Receiving, by the UE, data that is retransmitted by using the transmission mode in the second transmission mode according to the second indication, and performing decoding. To ensure that the method shown in the embodiment of the present invention can also be applied to HARQ.

Exemplarily, the information of the at least one TTI set includes information of a periodic TTI set, where the information of the periodic TTI set includes a period of the set of periodic TTIs and a set of the periodic TTIs. The offset of the TTI. Illustrative,

When the semi-static configuration signaling carries one of the first TTI set information and the second TTI set information, the method further includes: performing, according to the semi-static configuration signaling, the one TTI The set information determines another TTI set information in the first TTI set information and the second TTI set information.

For example, for Hybrid Automatic Repeat Request (HARQ) transmission, if the network device sends a DCI to the UE for scheduling uplink transmission in the TTI with the number n, the UE is numbered n+4. The TTI sends the PUSCH, and the network device sends an ACK/Negative Acknowledge (NAK) to the UE at the TTI numbered n+8, and notifies the UE whether the network device correctly decodes the PUSCH information sent by the UE; if the information is NAK If the network device fails to correctly decode the PUSCH, the UE retransmits the PUSCH to the network device again at the TTI numbered n+12.
