Description

Resource sharing method, network element and system based on competition

Technical Field

The present invention relates to a Long term evolution Advanced system (Long term evolution, LTE-Advanced for short), and in particular, to a resource sharing method, network element and system based on contention.

Background

With the continuous progress of radio technology, various radio services emerge in large quantities, and the frequency spectrum resources supported by the radio services are limited, so that the frequency spectrum resources show a very nervous situation in the face of the continuous increase of bandwidth requirements of people; on the other hand, under the conventional fixed spectrum allocation mode, the utilization rate of the spectrum resources is not high. In a sense, the spectrum allocation system fixedly allocated to the authorized system causes a situation of extremely tight spectrum resources. The cognitive radio technology breaks through a traditional spectrum fixed allocation system, dynamically allocates the spectrum among systems, and improves the utilization efficiency of the spectrum. Typically, as the daily communication demand of people is continuously increased and is not satisfied with simple voice data communication, the proportion of video streaming media service in the communication life of people is continuously increased, which requires larger bandwidth as a support, and the International Mobile Telephone (IMT) system shows an unprecedented spectrum tension.

Spectrum dynamic configuration is a potential technical feature of future networks, since cell sizes are moving towards smaller levels in the future due to the network's spectrum usage efficiency, and the possible extension towards higher frequency bands. The number of terminals in the cell becomes smaller, which means that the burstiness of the cell service is enhanced, the cell-level load is not as stable as the traditional network, and the dynamic property of the resource demand is improved. This is embodied in: 1. dynamically increasing or decreasing the frequency spectrum outside the system bandwidth, namely the use of the unlicensed frequency spectrum; 2. and within the system bandwidth, dynamically scheduling.

Due to the improvement of the dynamic property of resource allocation, the problem of interference under the condition of multiplexing the same frequency spectrum among cells is more complicated, higher requirements are provided for the interference coordination technology among adjacent cells, and a relatively static interference coordination mode under the traditional mode cannot meet the requirements. The problem that the interference coordination processing cannot keep up with the change of the interference state often occurs, so that the resource allocation efficiency is reduced, and the overall throughput of the system is greatly influenced.

Example 1

As shown in fig. 5, a macro cell terminal (MUE) interferes with a micro cell communication site (HeNB) in a heterogeneous network (all are FDD (Frequency Division duplex) system). The MUEs are located at the edge of the Femto cell coverage, and uplink transmission of MUEs will cause interference to Femto, and the procedure for configuring MUEs competing for the shared mode, and the procedure for MUEs competing for obtaining uplink transmission resources, are described in detail below. In this embodiment, a heterogeneous network formed by the HeNB and the eNB is taken as an example for description, and other forms of heterogeneous networks are all applicable.

As shown in fig. 6, the macro cell base station eNB determines a contention sharing domain and sends the contention sharing domain to the micro cell base station HeNB, and specifically, the eNB may determine the position and size of the time-frequency domain resource set as the contention sharing domain according to the current load condition and the number of terminals that need to be scheduled to the contention sharing domain. In this embodiment, the eNB sets subframe1, 2, 6, and 7 of each radio frame in the uplink frequency band as a contention sharing domain.

The eNB judges whether the MUE meets a predefined condition, and decides whether to schedule the MUE on a competitive shared domain based on the judgment result. The specific judgment process is as follows:

1. a decision criterion is preset, preferably, the eNB may determine, according to a potential interference situation of the MUE to the HeNB, for example, a measurement result of reference signal received power, RSRP, of the HeNB by the MUE, where the decision criterion is: rsrp (HeNB) > a dBm (that is, it is described that the distance between the MUE and the HeNB is within a certain range, the MUE uplink transmission has a possibility of interfering with the HeNB, a specific distance may be controlled by setting different threshold a values, in this embodiment, a is set to 10), that is, when the measured value of the HeNB reference signal received power reported by the MUE is higher than 10dBm, the MUE is considered to satisfy a predefined condition;

2. the MUE measurements are configured and the measurement results are received. Based on the decision criterion set in the foregoing, it is necessary to obtain the measurement result of the MUE on the HeNB reference signal received power, therefore, the MUE is configured with the reference signal received power for measuring the HeNB, and the measurement report of the received MUE is: and P is 12dBm, exceeds a preset threshold and meets a predefined condition.

Therefore, it is determined to schedule this MUE to the contention shared domain.

The eNB sends a competition sharing configuration message to the MUE, wherein the competition sharing configuration message is used for indicating the terminal meeting the predefined criterion to enter a competition sharing mode, standardizing the time-frequency resource range of a competition sharing domain and configuring parameters on the competition sharing domain;

the contention sharing mode refers to that the terminal meeting the predefined criteria is scheduled to a contention sharing domain, and the terminal needs to obtain an uplink transmission opportunity on the contention sharing domain in a contention manner;

time-frequency domain position information of a contention sharing domain (

subframe

1, 2, 6, 7 of each radio frame of an uplink frequency band); configuration parameters on the contention-shared domain, including the following information: the contention algorithm (LBT) used, the frequency domain contention granularity (the whole system bandwidth, e.g. 5MHz), the time domain contention granularity 1ms, the maximum contention window length 1ms, and the minimum contention window length 0.1 ms.

In this embodiment, the frequency domain contention granularity is defined as the entire system bandwidth, that is, when the MUEs contend for the transmission opportunity, the ue will occupy the entire system bandwidth to transmit uplink data.

The time domain contention granularity refers to the time domain granularity for which the terminal contends, that is, the time duration that the MUE can occupy to the transmission opportunity, that is, 1 ms.

After receiving the contention sharing configuration message, the MUE enters a contention sharing mode according to the requirement of the configuration message, so as to make a contention algorithm (LBT) to contend for a transmission opportunity on the contention sharing domain with other UEs which are also scheduled to the contention sharing domain.

MUEs contend for a certain transmission opportunity (e.g., frame1 subframe 2), and transmit uplink data to the eNB over the full bandwidth on frame1 subframe 2. Preferably, when uplink data is transmitted, the MUE carries its own identification information, so that the eNB receives the identification. The identification information may be a specific sequence that uniquely identifies the MUE, or a specific data transmission scheme.

The eNB monitors uplink data on time-frequency resources corresponding to all contention sharing domains, and identifies whether the uplink data is data to be received by itself and from which terminal, by combining identification information included in the uplink data.

Example 2

As shown in fig. 7, in a heterogeneous network (all are TDD systems), two uplink interferences exist between macro and micro systems: namely, a macro cell terminal (MUE) interferes with a macro cell base station (HeNB), and the micro cell terminal HeNB interferes with the macro cell base station eNB. The following describes in detail the contention sharing mode configuration procedure for MUEs and HUE, and the procedure of contention acquisition of uplink transmission resources between MUEs and HUE. In this embodiment, a heterogeneous network formed by the HeNB and the eNB is taken as an example for description, and other forms of heterogeneous networks are all applicable.

As shown in fig. 8, the macro cell base station eNB and the micro cell base station HeNB negotiate to determine a contention sharing domain, specifically, the eNB and the HeNB interact with the current load condition, and the number of terminals that need to be scheduled to the contention sharing domain, and determine the position and size of the time-frequency domain resource set as the contention sharing domain by combining the information of both parties. In this embodiment, part of uplink subframes of the TDD system are set as contention sharing domains, the uplink and downlink subframes of the system are configured as DSUUDs, and subframe2 and subframe 7 of each radio frame are set as contention sharing domains.

And the HeNB and the eNB respectively judge and determine the subordinate terminals meeting the predefined condition. The specific judgment process is as follows:

1. the eNB determines whether the subordinate MUE1-3 meets the predefined condition, and the specific process is the same as that in embodiment 1, which is not described herein again. The judgment result is: the MUE1 and the MUE2 meet the preset judgment criterion and determine that the two MUE are scheduled to the competition sharing domain.

2. The HeNB judges whether subordinate HUE1 and HUE2 meet predefined conditions or not, the HeNB configures the subordinate terminals to measure the reference signal receiving power of the HeNB and the eNB respectively, and the judgment criterion is set to be P (HeNB) < B dBm and P (eNB) > C dBm, at the moment, the HUE meeting the conditions is far away from the HeNB, and the corresponding transmitting power is relatively large; and closer to the eNB, more likely to interfere with the eNB. Based on the above criteria, respectively sending measurement configuration messages to the HUE, receiving measurement results and reporting, comparing the measurement results with the judgment criteria to obtain that the HUE2 meets the preset judgment criteria, and determining to schedule the HUE2 to the competition shared domain.

Note: the communication station can also respectively judge different UEs at different times and schedule the UEs meeting the predefined condition to the contention sharing domain at any time.

The HeNB and the eNB respectively send competition sharing configuration messages to the UE (MUE1, MUE2 and HUE2) meeting predefined conditions, wherein the competition sharing configuration messages are used for indicating the terminal meeting the predefined criteria to enter a competition sharing mode, and specifying the time-frequency resource range of a competition sharing domain and configuration parameters on the competition sharing domain;

time-frequency domain location information of the contention-shared domain (subframe 2, 7 of each radio frame); configuration parameters on the contention-shared domain, including the following information: the contention algorithm (LBT) used, the frequency domain contention granularity (dividing the system bandwidth into sub-bands, e.g. for 10MHz, into two sub-bands, each sub-band being 25 RBs), the maximum occupancy duration being 0.5ms, the maximum contention window being 1ms long, and the minimum contention window being 0.1ms long.

In this embodiment, the frequency domain contention granularity is defined as a frequency domain width of 25 RBs, that is, when the MUEs contend for the transmission opportunity respectively for the sub-bands 1 and 2, and when the contention succeeds, the uplink data is transmitted with the bandwidth occupying the contended sub-band.

The maximum occupied time is 0.5ms, which is the time that the MUE can occupy to the transmission opportunity, i.e. 0.5 ms.

After receiving the contention sharing configuration message, each UE enters a contention sharing mode according to the requirement of the configuration message, and contends for a transmission opportunity on a contention sharing domain by using a formulated contention algorithm (LBT).

The contention results for frame0 and subframe2 for each UE are shown in fig. 6. And the UE sends uplink data to the respective base station on the respective contended time-frequency resources. Preferably, when transmitting uplink data, the UE carries its own identity information, so that the eNB/HeNB receives the identification.

When the terminal sends the uplink data, the base station does not know which terminal occupies which time-frequency resource, so the HeNB and the eNB monitor the uplink data on the time-frequency resources corresponding to all the contention sharing domains, and identify whether the data is to be received by the HeNB and the eNB from which terminal by combining the identification information contained in the uplink data.

Example 3

As shown in fig. 10, in the isomorphic network scenario, uplink interference exists between macro cells: i.e., uplink transmissions of macro cell edge terminals (UEs) potentially interfere with reception by neighboring cell base stations eNB. The following describes in detail the contention sharing mode configuration process of the eNB for each subordinate UE and the process of contention acquisition of uplink transmission resources among macro-cell UEs. .

As shown in fig. 11, the upper management node configures a contention sharing domain (shaded in the figure) for the communication station, determines that resources of a part of subbands (for example, the system bandwidth is 20MHz, and the subband range is 60 th RB to 69 th RB) in the system bandwidth are used as contention sharing resources, and configures the contention sharing resources to each eNB;

the upper management node may be an entity located on the network management side or an entity located on the core network side. And may even be manually configured.

The eNB a, eNB B, and eNB C respectively schedule respective edge UEs to a contention sharing domain, configure the edge UEs into a contention sharing mode, and specifically include the following UEs: UE (user Equipment)_A1、UE_A2、UE_B1、UE_B2、UE_C1、UE_C2。

Each eNB sends a request to a UE (UE) satisfying a predefined condition_A1、UE_A2、UE_B1、UE_B2、UE_C1、UE_C2) Sending a competition sharing configuration message, wherein the competition sharing configuration message is used for indicating the terminal meeting the predefined criterion to enter a competition sharing mode, and standardizing the time-frequency resource range of a competition sharing domain and configuration parameters on the competition sharing domain;

time-frequency domain position information of the contention sharing domain: frequency domain: 60 th to 69 th RBs; time domain: full period (which may not be included at this time, default full period); configuration parameters on the contention-shared domain, including the following information: the competition algorithm (LBT) used. In this embodiment, the system already defaults to specific configuration parameters under the contention algorithm, so in the configuration message, it only needs to determine which contention algorithm is adopted, and no specific configuration parameters are needed.

And each UE sends uplink data to each base station on the time-frequency resource which is contended by each UE. Preferably, before the uplink data is sent, the UE first sends the contention success indication information to the eNB to which the UE belongs, and the indication information carries the identification information of the UE, so that the eNB/HeNB receives the subsequent uplink data.

And each eNB monitors competition success indication information on the competition shared domain, continues to receive the subsequent uplink data when the indication information shows that the uplink data is sent to the eNB, and abandons the subsequent reception otherwise.

Example 4

As shown in fig. 12, in a scenario of coexistence of different systems, both the UMTS cell and the LTE cell are FDD systems, and overlap coverage or are adjacent to each other, and when two systems share a spectrum, uplink interference between the systems exists: i.e. uplink transmissions of terminals (UEs) within the coverage overlap area potentially cause interference to reception by the different system base stations eNB. The following describes in detail the contention sharing mode configuration process and the process of contention acquisition of uplink transmission resources among UEs in each system. In this embodiment, a scenario in which UMTS and LTE coexist is taken as an example for description, and other scenarios of spectrum sharing between different systems are all applicable.

The two systems are both FDD systems, the scheme is designed aiming at uplink bandwidth, the bandwidth of a UMTS system participating in competition sharing is 5MHz, the bandwidth of an LTE system is 10MHz, and the central frequency points of the two systems are the same. Determining the size of the contention sharing domain of the two systems according to the load status of the two cells, as shown in fig. 13, determining to set the shaded portion as the contention sharing domain, and defining the time-frequency domain range of the contention sharing domain by the frame structure of the LTE system: the time domain is the second time slot of each subframe, and the frequency domain is the middle 5MHz of the system bandwidth. For the UMTS system, the frequency domain range of the contention based shared domain relates to the whole system bandwidth, the time domain needs to be synchronized with the LTE system, and the corresponding time-frequency domain resource is found and set as the contention based shared domain.

The NodeB and the eNB respectively schedule the terminal potentially causing interference to the neighboring cell to a competition shared domain, the terminal potentially causing interference to the neighboring cell can be obtained by respective base stations according to the measurement result of the subordinate terminal to the neighboring cell, for example, when the reception power of the NodeB subordinate terminal to the eNB exceeds a certain threshold, the terminal is considered to be in the coverage range or coverage edge of the eNB subordinate cell, and the uplink transmission of the terminal potentially causes interference to the reception of the eNB.

The NodeB and the eNB respectively send competition sharing configuration messages to terminals which are subordinate to the respective terminals and expected to be scheduled to a competition sharing domain, wherein the competition sharing configuration messages are used for indicating the terminals meeting the predefined criterion to enter a competition sharing mode, standardizing the time-frequency resource range of the competition sharing domain and configuring parameters on the competition sharing domain;

time-frequency domain position information of the contention sharing domain: the two systems allocate time-frequency domain resource positions corresponding to the competitive sharing domains of the respective systems to the subordinate terminals. Configuration parameters on the contention-shared domain, including the following information: competition algorithm employed (CSMA/CA, Carrier Sensing Multi Access/colloid Avoidance). In this embodiment, the system already defaults to specific configuration parameters under the contention algorithm, so in the configuration message, it only needs to determine which contention algorithm is adopted, and no specific configuration parameters are needed.

After receiving the configuration message of the competition sharing, each UE enters into a competition sharing mode according to the requirement of the configuration message, and mutually competes for the transmitting opportunity on a competition sharing domain by a formulated competition algorithm.

It is worth noting that: in the above embodiment, the setting of the contention based shared domain may be performed dynamically, that is, the time-frequency domain resource location of the contention based shared domain may be readjusted according to the current network state, and the updated contention based shared domain information may be sent to the terminal scheduled to the contention based shared domain through the processes of the embodiments.

Example 5

As shown in fig. 14, in the isomorphic network scenario, uplink interference exists between macro cells: that is, uplink transmission of macro cell edge terminals (UEs) potentially interferes with reception of neighboring cell base stations eNB B, eNB C. The following describes in detail the configuration process of eNB a canceling the contention sharing mode for the UE when the UE moves to the cell center and is not a potential interference source of the neighboring cell.

The UE is a terminal which is subordinate to the eNB A and is scheduled to a competition sharing domain, the UE participates in competition with other UE on the competition sharing domain, RSRP of the service base station eNB A is measured, a measurement result shows that the UE has moved to a cell center, namely a white area, and potential interference on adjacent cells eNB B and eNB C cannot be caused by uplink transmission of the UE.

The eNB sends an indication message to the UE, indicates the UE to cancel the contention sharing mode and recovers the normal scheduling mode; and the UE later uplink transmission is recovered to the LTE normal scheduling mode.

Similarly, in other scenarios, the communication station may also determine whether the terminal continues to be scheduled on the contention sharing domain according to the state change of the terminal scheduled on the contention sharing domain, and may decide to change its operating mode to the normal mode at an appropriate time.

Example 6

As shown in fig. 15, in a case of a homogeneous network application corresponding to the present invention, uplink interference exists between macro cells: i.e., uplink transmissions of macro cell edge terminals (UEs) potentially interfere with reception by neighboring cell base stations eNB. The following describes in detail the collision avoidance procedure between the terminal and the legacy terminal in the contention sharing mode, so as to achieve compatibility with the legacy terminal.

Similar to embodiment 3, the process of configuring the contention sharing domain by the upper management node (as shown in fig. 11) is performed in sequence; each base station determines that each edge user is scheduled to a competition sharing domain; the terminals entering the competition sharing mode compete for respective transmitting opportunities on a competition sharing domain;

the difference lies in that: the conventional terminal UE2 exists under eNB a, and since the conventional terminal cannot identify messages such as contention based shared domain configuration, if no special processing is applied to the conventional terminal, uplink transmission of the UE2 may occur in the contention based shared domain, potentially causing a conflict with the terminal in the contention based shared mode. In order to realize compatibility between the terminal and the legacy terminal in the contention sharing mode, eNB a needs to limit uplink resources of the legacy terminal UE2, that is, uplink transmission of UE2 is not scheduled within the contention sharing domain, and no uplink transmission is allowed in the contention sharing domain. Thereby avoiding resource conflicts between the UE2 and the contention sharing mode UE over the contention sharing domain.

It is worth mentioning that: in this embodiment, the uplink resource occupation of the legacy terminal is limited by the communication station, so as to avoid uplink collision with the contention sharing mode terminal in the contention sharing domain, and finally achieve compatibility with the legacy terminal;

the communication station also can perform limited pre-configuration on the competition sharing mode terminal to realize the compatibility of the traditional terminal; at this time, it is necessary to add limitation pre-configuration information in the contention sharing configuration message, so as to indicate the time frequency resources that are limited to be used in the contention sharing domain to the terminal in the contention sharing mode, where the time frequency resources that are limited to be used are occupied by the uplink transmission of the conventional terminal. Therefore, the conflict avoidance of the uplink resources of the two terminals is realized, and the traditional terminal is compatible.

Example 7

The UE is instructed by the eNB to enter the contention sharing mode by the method described in any of the above embodiments, and the determining and instructing processes of the sending mode of the UE in the contention sharing domain are described in detail in this embodiment.

In order for the eNB to correctly demodulate uplink data of the UE on the contention sharing domain, the eNB indicates the following information to the UE in the contention sharing configuration message: time-frequency domain position of transmission opportunity starting point, MCS level limit, Transmission Mode (TM) limit, uplink resource allocation type limit.

The time-frequency domain position of the transmission opportunity starting point refers to time-frequency domain resource information corresponding to the starting points of all transmission opportunities in the shared contention domain, and is used for limiting the transmission starting point of the uplink data of the UE. It is also convenient for the eNB to distinguish different transmission opportunities when detecting UE uplink data.

The MCS level restriction is configured to restrict an MCS level adopted by the terminal to transmit uplink data in the contention based shared domain, or an MCS level set (restricted to MCS10 in this embodiment); the transmission mode restriction is used to limit a transmission mode or a transmission mode set (limited to TM1 in this embodiment) that the terminal uses to send uplink data in the contention sharing domain. The uplink resource allocation Type limitation is used to limit the uplink resource allocation Type of the terminal in the contention sharing domain (in this embodiment, the limitation is Type0, and the number of RBs is 15).

And the UE contends for the uplink transmitting resource according to a specified contention algorithm, and after the UE contends to the transmitter, the UE transmits uplink data on the contended time-frequency resource according to the indication of the transmitting mode and the specified MCS level, the transmission mode and the uplink resource allocation type.

Until the uplink data of the UE is successfully demodulated, thereby completing the process of receiving the uplink data of the UE on the contention sharing domain.

It is worth noting that: the eNB may refer to CQI feedback previously made by the UE when defining MCS level, transmission mode, uplink resource allocation type for uplink transmission by the UE. There are two possible ways for the UE to feed back CQI in the contention sharing mode: 1. the CQI feedback mode of the first class terminal is the same as that of the traditional terminal, and the time-frequency resources corresponding to the competitive shared domain need to be avoided, namely the first class terminal also needs to perform CQI feedback on the non-competitive shared domain resources; 2. the CQI feedback of the first class of terminals also needs to be performed in the contention-based shared domain, that is, the UE needs to contend for the time-frequency resource to feed back the CQI, and the content to be fed back is sent to the eNB in the contended time-frequency resource in the sending manner indicated by the eNB. In any of the above manners, after receiving the CQI feedback of the UE, the eNB determines the corresponding MCS level, transmission mode, and uplink resource allocation type, and indicates the MCS level, transmission mode, and uplink resource allocation type to the UE through a downlink channel or a signal.

The configuration information of the uplink data transmission scheme indication field is used for the eNB to indicate the transmission scheme (referred to as a first transmission scheme) adopted by the "uplink data transmission scheme indication field" itself to the UE.

The uplink data sending mode indication field is sent together with the first class terminal uplink data, and can be placed at a specific position, such as the front or the back of the uplink data, and occupy a certain amount of bit resources. The sending mode comprises the following steps: MCS level, transmission mode, resource allocation type.

In this embodiment, the uplink data transmission mode indication field is placed in front of the uplink data and occupies N bits, and in this case, the eNB may demodulate the uplink data transmission mode indication field at the time-frequency domain position of the transmission opportunity start point according to the specified transmission mode. And further reading the uplink data transmission mode contained in the data.

In this embodiment, the UE contends for the uplink transmission resource according to a designated contention algorithm, and after the UE contends for the transmitter, the UE transmits uplink data on the contended time-frequency resource according to the indication of the transmission mode and the MCS level, the transmission mode, and the uplink resource allocation type determined by the UE. And indicating the transmission mode information of the uplink data to the eNB in the indication field before the uplink data according to the configuration information of the uplink data transmission mode indication field.

The eNB successfully demodulates an "uplink data transmission mode indication field" at the starting point of a certain uplink transmission opportunity, and obtains the following uplink data transmission mode: the MCS10, the transmission mode is TM1, the uplink resource allocation Type is Type0, and the RB number is 15.

Example 9

The UE is instructed by the eNB to enter the contention sharing mode by any one of the methods described in the above embodiments one to six, and this embodiment describes in detail another process of determining and instructing the sending mode of the UE in the contention sharing domain.

In order for the eNB to correctly demodulate uplink data of the UE on the contention sharing domain, the eNB indicates the following information to the UE in the contention sharing configuration message: time-frequency domain location of the start of the transmission opportunity, MCS level restriction, Transmission Mode (TM) restriction.

The MCS level restriction is configured to restrict an MCS level adopted by the terminal to transmit uplink data in the contention based shared domain, or an MCS level set (restricted to MCS10 in this embodiment); the transmission mode restriction is used to limit a transmission mode or a transmission mode set (limited to TM1 in this embodiment) that the terminal uses to send uplink data in the contention sharing domain.

The UE contends for the uplink transmission resource according to a specified contention algorithm, and after the UE contends for the transmitter, according to the indication of the sending method, sends uplink data on the contended time-frequency resource with a specified MCS level and a specified transmission mode, and indicates an uplink resource allocation Type (in this embodiment, the restriction is Type0, and the number of RBs is 15).

And the eNB receives and tries to demodulate the uplink data in each transmission opportunity according to the corresponding MCS level and the transmission mode. Until the uplink data of the UE is successfully demodulated, thereby completing the process of receiving the uplink data of the UE on the contention sharing domain.

Example 10

In order for the eNB to correctly demodulate the CQI feedback information of the UE on the contention sharing domain, the eNB indicates the following information to the UE in the contention sharing configuration message: time-frequency domain location of the start of the transmission opportunity, MCS level restriction, Transmission Mode (TM) restriction.

When the UE needs to feed back the CQI, the UE competes for the uplink transmission resource according to a specified competition algorithm, and after the UE competes to a transmitter, the UE sends the CQI information according to the sending mode indicated in the competition sharing configuration message, namely the CQI information is sent on the competed time-frequency resource by the specified MCS level and the transmission mode.
