Description

Data transmission method, terminal device and network device

This application claims the priority of the Chinese Patent Application filed on November 24, 2017, the Chinese Patent Application No. 201711194357.8, the entire disclosure of which is hereby incorporated herein In the application.

Technical field

The present application relates to the field of communications, and in particular, to a data transmission method, a terminal device, and a network device in the field of communications.

Background technique

In a wireless communication system, in order to improve transmission efficiency while ensuring transmission reliability, a network device generally estimates the quality of a wireless channel for transmitting signals, and determines a scheduling scheme according to the quality of the wireless channel. In current wireless communication systems, quality information of a wireless channel is usually obtained by means of a transmission reference signal. Communication systems typically use different kinds of reference signals: one type of reference signal is used for channel quality measurement, such as cell-specific reference signal (CRS), so that channel quality measurement and cell selection and handover can be implemented; The reference signal is used for measurement of channel state information to enable scheduling of the terminal device. For example, the terminal device can obtain corresponding channel state information CSI based on channel quality measurement of a channel state information reference signal (CSI-RS).

To overcome large propagation losses, a common signal transmission mechanism based on beamforming techniques is employed to compensate for the aforementioned losses in the propagation of common signals through larger antenna gains. The network device needs to send a reference signal to the terminal device during the beam training process. Therefore, the network device needs to configure the reference signal resource set for the terminal device, and the reference signal resource set includes multiple reference signal resources, and the network device can indicate to the terminal device that the type of the reference signal resource set is “ON” by using the high layer signaling. Or "OFF". When the reference signal resource set type is "ON", the terminal device assumes that the transmission beam of the network device is fixed, that is, the plurality of reference signal resources of the reference signal resource set correspond to the same beam, and is used to train the receiving beam of the terminal device. The device does not feed back the reference signal resource index. When the reference signal resource set type is "OFF", the terminal device assumes that the transmission beam of the network device is not fixed, that is, the reference signal resource set corresponds to multiple different beams, and is used to train the transmission beam of the network device. The reference signal resource index is fed back, that is, the at least one beam that is better is selected by measuring the multiple beams sent by the network device, and the index of the at least one beam is reported to the network device.

In the above beam training process, the network device may configure a plurality of reference signal resource sets for the terminal device, where the reference signal resource set includes multiple beams for any one of the plurality of reference signal resource sets ( Beam), for example, b1-b8. In order to train the transmit beam and the receive beam at the same time, the network device may use the multiple reference signal resource sets to send reference signals to the terminal device on multiple time units, and the terminal device needs to report the reference signal measurement to the network device on each time unit. As a result, in the process of creating the present invention, the inventor found that when the terminal device reports the reference signal measurement result to the network device, the reporting overhead is large.

It should be understood that multiple-input multiple-output (MIMO) technology refers to multiple transmitting and receiving antennas respectively used by the transmitting device and the receiving device, so that the signal passes through multiple devices of the transmitting device and the receiving device. Antenna transmission and reception improve communication quality. It can make full use of space resources and achieve multiple transmission and reception through multiple antennas. It can multiply the system channel capacity without increasing spectrum resources and antenna transmission power.

MIMO can be divided into single-user MIMO (SU-MIMO) and multi-user MIMO (MU-MIMO). Based on the principle of multi-user beamforming, Massive MIMO arranges hundreds of antennas at the transmitting end, modulates the respective beams for dozens of target receivers, and transmits dozens of signals simultaneously on the same frequency resource through spatial signal isolation. Therefore, Massive MIMO technology can make full use of the spatial freedom brought by large-scale antenna configuration to improve spectrum efficiency.

As shown in FIG. 1, the communication system 100 includes a network device 102, which may include multiple antenna groups.

terminal devices

116 and 122 in the relevant coverage area, the network device 102 uses a single antenna to transmit signals to all of its terminal devices. Mobile devices are subject to less interference.

At a given time, network device 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting device and/or a wireless communication receiving device. When transmitting data, the wireless communication transmitting device can encode the data for transmission. Specifically, the wireless communication transmitting device may acquire a certain number of data bits to be transmitted to the wireless communication receiving device through a channel, for example, the wireless communication transmitting device may generate, receive from another communication device, or save in a memory, etc., to be transmitted through a channel. A certain number of data bits to the wireless communication receiving device. Such data bits may be included in a transport block or a plurality of transport blocks of data, and the transport blocks may be segmented to produce a plurality of code blocks.

In addition, the communication system 100 may be a public land mobile network PLMN network or a device to device (D2D) network or a machine to machine (M2M) network or other network, and FIG. 1 is merely an example for convenience of understanding. A simplified schematic diagram of the network may also include other network devices, which are not shown in FIG.

In current wireless communication systems, quality information of a wireless channel is usually obtained by means of a transmission reference signal. Communication systems typically use different kinds of reference signals: one type of reference signal is used for channel quality measurement, such as cell-specific reference signal (CRS), so that channel quality measurement and cell selection and handover can be implemented; The reference signal is used for measurement of channel state information to enable scheduling of the terminal device. For example, the terminal device can obtain corresponding channel state information CSI based on channel quality measurement of a channel state information reference signal (CSI-RS).

In order to measure the channel quality, the network device may send a plurality of reference signals to the terminal device, where the number Q of channel quality information that needs to be reported may be predefined, or the network device is configured to the terminal device by using signaling. Q is an integer greater than or equal to 1. The terminal device receives the plurality of reference signals sent by the network device, and based on the configuration of the network device, measures all the reference signals sent by the network device, obtains optimal Q channel quality information, and obtains the optimal Q information. The channel quality information is reported to the network device.

With the development of communication technology, the signal transmission mechanism based on the beamforming technology can be adopted for the reception and transmission of the reference signal to compensate the loss in the signal propagation process by the larger antenna gain, thereby ensuring the uplink coverage performance and the cell. Significant improvements in parameters such as average throughput and edge user rate. The beamforming technology is any one of beamforming in the analog domain, beamforming in the baseband domain, and hybrid beamforming, and the beamformed signal may be a cell-specific first type reference signal. It can also be a user-specific second type of reference signal, etc., and can also be other reference signals.

Specifically, the beam management mechanism based on beamforming signal transmission includes three main processes:

(1) selecting an optimal one or more transceiver beam pairs for the terminal device to select an optimal transmit beam and/or a receive beam based on different beam scans on the network device side;

(2) update of the transmit beam, used by the terminal device to update the transmit beam based on scanning of different transmit beams on the network device side;

(3) The update of the receive beam is used by the terminal device to update the receive beam by repeating the same transmit beam scan multiple times on the network device side;

The terminal device can track and update the transceiver beam through the above beam management mechanism.

In the beamforming-based signal transmission mechanism, optionally, the reference signal is in one-to-one correspondence with the beam, and the channel quality information corresponding to the reference signal also corresponds to the beam one-to-one. In order to measure the channel quality based on the plurality of reference signals for tracking and updating the beam, the optimal number of beams Q reported by the terminal device is the number Q of channel quality information corresponding to the beam.

In general, the network device needs to configure the reference signal resource set for the terminal device, and the reference signal resource set includes multiple reference signal resources, and the network device can indicate to the terminal device that the type of the reference signal resource set is “ ON" or "OFF". When the reference signal resource set type is "ON", the transmission beam of the network device is fixed, that is, the plurality of reference signal resources of the reference signal resource set correspond to the same beam, and the training beam of the terminal device is trained, and the terminal device does not feedback at this time. Reference signal resource index. When the reference signal resource set type is "OFF", the transmission beam of the network device is not fixed, that is, the reference signal resource set corresponds to multiple different beams, and is used to train the transmission beam of the network device. At this time, the terminal device needs to feed back the reference signal. The resource index, that is, the at least one beam is selected by the plurality of beam measurements sent by the network device, and the index of the at least one beam is reported to the network device.

It should be understood that, in this embodiment of the present application, the reference signal resource may include at least one of a time domain resource for transmitting a reference signal, a frequency domain resource, and a spatial domain resource (eg, a beam, a spatial domain transmission filter). The index of the reported beam of the terminal device may also be an index for reporting the reference signal resource corresponding to the beam. The spatial domain resource may be referred to as a beam, and may also be referred to as a spatial domain transmission filter, which is not limited in this embodiment of the present application. It should be understood that in this context, a spatial domain transmit filter is equivalent to a beam.

The network device may send the reference signal to the terminal device by using the multiple reference signal resource sets on the multiple time units, and the terminal device needs to report the result of the reference signal measurement to the network device on each time unit. In general, the terminal device measures the reference signal and reports the channel quality information in each time unit. For example, if the network device transmits the reference signal on the first time unit, the beam used is b1-b8, and the terminal device passes the measurement report b1. The index is that the beam used for transmitting the reference signal on the second time unit is still b1-b8, and the terminal device still reports the index of b1 after being measured, which causes the terminal device to repeatedly report, and the signaling overhead is large. In order to solve this problem, the embodiment of the present application proposes a new method.

FIG. 2 shows a schematic flowchart 200 of a data transmission method of an embodiment of the present application. The method 200 can be applied to the communication system 100 shown in FIG. 1, but the embodiment of the present application is not limited thereto.

S220, the network device sends a reference signal to the terminal device by using a reference signal resource in the N reference signal resource sets; correspondingly, the terminal device receives, by the network device, the N reference signal resources. a reference signal transmitted by a reference signal resource in the set;

S230, the terminal device sends channel quality information measured by the reference signal, where the first parameter L is used to indicate that the channel quality information is that the terminal device measures a reference signal corresponding to L reference time units. Each of the L reference time units corresponds to a set of N reference signal resources, and L is an integer greater than or equal to 2;

In an implementation manner, the number of bits of the channel quality information is less than K times L, where K is a number of bits required by the terminal device to report channel quality information in each reference time unit, where K is greater than or An integer equal to 1;

Correspondingly, the network device receives the channel quality information sent by the terminal device according to the first parameter L and the first configuration information.

Specifically, the network device may first configure, by using the first configuration information, the N reference signal resource sets, where the N reference signal resource sets include reference signal resources used by the network device to send the reference signal to the terminal device. Then, the network device may send a reference signal to the terminal device by using the reference signal resource in the configured N reference signal resource sets, and the terminal device receives the reference signal and measures the reference signal. As described above, the terminal device can select the optimal Q channel quality information from the measurement result and report it to the network device.

In the embodiment of the present application, there is a first parameter L, which is known by both the network device and the terminal device, and the first parameter L is used to indicate the reporting period of the terminal device, that is, the terminal device can synthesize the reference signals of the L reference time units. As a result of the measurement, the optimal Q channel quality information is selected, and the channel quality information is reported to the network device. Since each reference time unit corresponds to N reference signal resource sets in the L reference time units, that is, the network device repeatedly uses the N reference signal resource sets to transmit the reference signal, the terminal device can combine the first parameter L. The first configuration parameter L determines the content of the channel quality information, and the different first parameter L corresponds to different channel quality information selection manners, and the channel quality information may have different bit numbers under different channel quality information content. For the same reason, the network device can also determine the content of the report of the terminal device, so as to determine the channel quality information to be reported by the terminal device, so as to accurately receive the channel quality information reported by the terminal device.

As an optional embodiment, the first parameter L is predefined; or the first parameter L is that the network device is configured by using the signaling for the terminal device.

Specifically, the foregoing first parameter L may be predefined, or may be configured by the network device by using the signaling, and is not limited by the embodiment of the present application. It should be understood that, in a case where the network device configures the first parameter L for the terminal device by signaling, the first parameter may be included in the foregoing first configuration information.

As an optional embodiment, the signaling is radio resource control RRC signaling, downlink control information DCI, or media access control control element MAC CE.

Specifically, the signaling that is sent by the network device to the terminal device for carrying the first parameter may be radio resource control (RRC) signaling or downlink control information (DCI). The media access control (MAC) layer control element (CE) signaling may be used in the embodiment of the present application.

It should be understood that the configuration of the first parameter by using RRC signaling is applicable to a scenario in which the configuration of the first parameter does not change frequently and is relatively stable, and the bit overhead of signaling of the physical layer and the MAC layer can be greatly saved. The configuration of the first parameter by using the DCI is advantageous for the terminal device to perform fast detection and ensure that the terminal device receives the first parameter in time. The first parameter configured by using MAC CE signaling is applicable to a scenario in which the change of the first parameter is relatively dynamic. Since the decoding speed of the MAC CE signaling is faster than the RRC signaling, in such a scenario, the network device uses the MAC CE signaling to configure the first parameter to be more efficient.

As an optional embodiment, the first configuration information is carried in at least one of RRC signaling, MAC CE, and DCI.

Specifically, in a case that the network device configures the foregoing N reference signal resource sets for the terminal device according to the periodic or semi-period scenario, the first configuration information may be RRC signaling, and the first configuration information may also be RRC signaling. And the MAC CE, where the network device configures the foregoing N reference signal resource sets for the terminal device based on the aperiodic scenario, the first configuration information may be RRC signaling and DCI, and the first configuration information may also be an RRC message. The embodiment, the MAC CE and the DCI, are not limited in this embodiment.

As an optional embodiment, the spatial reference transmit cells corresponding to the L reference time units are the same.

Specifically, each of the L reference time units corresponds to a set of N reference signal resources, that is, the network device repeatedly transmits the L reference time units on the L reference time units by using the reference signal resources in the N reference signal resource sets. Secondary reference signal. Therefore, the spatial domain transmission filters corresponding to the L reference time units are the same, and the number of spatial domain transmission filters corresponding to the L reference time units may be plural. It should be understood that the spatial domain transmit filter corresponding to the L reference time units may be a spatial domain transmit filter corresponding to the reference signal resource used by the reference signal transmitted on the L reference time units.

As an optional embodiment, the channel quality information includes an index of the first reference signal resource within the N reference signal resource sets.

As an optional embodiment, each of the N reference signal resource sets includes a maximum of W reference signal resources, where W is an integer greater than or equal to 1, and the number of bits of the channel quality information is

As an optional embodiment, the reference time unit is any one of a subframe, a time slot or a symbol.

The present application is described in detail below by way of a specific embodiment.

The network device configures a reference signal resource set (resource set) for the terminal device in the first configuration information, where the reference signal resource set includes 8 resources, and the corresponding beams are b1-b8. The reference signal corresponding to the reference signal resource set has a transmission period of 5 ms, that is, the network device uses the reference signal resource in the reference signal resource set to send a reference signal to the terminal device every 5 ms.

In addition, the first parameter L=2, the terminal device assumes that the beams corresponding to the two consecutive resource sets are the same, and measures and determines the reported channel quality information for the reference signals of the two consecutive reference time units. That is, the eight reference signals corresponding to b1-b8 in the first reference time unit are measured first, and the corresponding channel quality information is obtained. After 5 ms, the 8 reference signals corresponding to b1-b8 in the second reference time unit are measured to obtain corresponding channel quality information. The terminal device may report the optimal Q channel quality information of the channel quality information of the 16 reference signals after the measurement is completed. It should be understood that, optionally, the channel quality information reported by the terminal device does not include the index of the same reference signal resource, that is, the same index is not reported multiple times. In this case, the terminal device reports the reference signal resource index in each channel quality information.

If the terminal device reports the channel quality information to the network device in each reference time unit, 6 bits is required for the two reference time units, and in the embodiment of the present application, only 3 bits is needed, which saves the reporting overhead of the terminal device. .

The data transmission method in the embodiment of the present application is beneficial to reducing the reporting overhead of the terminal device and improving the feedback efficiency of the terminal device.

As an optional embodiment, the first parameter L is reported by the terminal device.

It should be understood that the first parameter L may also be obtained by the network device and/or the terminal device according to other parameters, for example, the number of receiving beams of the terminal device, the number of antenna panels of the terminal device, and the sending of the terminal device. The number of the receiving antennas, and the like, may be reported to the network device by the terminal device, or may be a pre-configured parameter, which is not limited in this embodiment of the present application.

Or the number of bits of the channel quality information is less than or equal to

Specifically, each reference signal resource set in the set of N reference signal resources configured by the network device includes at most W reference signal resources, and the number of bits of the channel quality information reported by the terminal device may be at most

or

It should be understood that, in the embodiment of the present application, since each reference signal resource set in the N reference signal resource sets includes a maximum of W reference signal resources, in a possible implementation manner, the terminal device may use all N reference signals. The resource set is numbered, that is, the number of coexisting numbers is less than N×W, so that the number of bits of the channel quality information is smaller than

Similarly, in another possible implementation manner, the terminal device may separately number each reference signal resource set, and then number the resources in each reference signal resource set, so that the first reference signal to be reported is reported. The number of bits of the index of the resource collection is

The number of bits of the index of the first reference signal resource in the first reference signal resource set depends on the number of reference signal resources in the first reference signal resource set, and the number of bits of the index of the first reference signal resource is less than or equal

Therefore, the number of bits of the channel quality information reported by the terminal device is less than or equal to

In this article, you can use the above rounding

The reference signal resource set includes a plurality of different beams, for example, b1-b8, and the terminal device defaults that the plurality of reference signal resource sets are configured with the same beam, and the order is the same, for example, at 3 In the set of reference signal resources, the beams of each reference signal resource set are b1-b8. However, in this case, the beams in the plurality of reference signal resource sets used by the network device to transmit the reference signal may be different, for example, b1-b8, b9-b16, b17-b24, and the terminal device still follows The default multiple signal signal sets include the same beam for reporting. For example, the beam index of b1-b8 is reported, which causes the content reported by the terminal device to be inaccurate. To solve this problem, the embodiment of the present application proposes a new method.

FIG. 3 shows a schematic flowchart 300 of a data transmission method in an embodiment of the present application. The method 300 can be applied to the communication system 100 shown in FIG. 1, but the embodiment of the present application is not limited thereto.

S310. The network device sends second configuration information to the terminal device, where the second configuration information is used to configure M reference signal resource sets, where each reference signal resource set in the M reference signal resource sets includes P reference signals. a resource, where M and P are integers greater than or equal to 1; correspondingly, the terminal device receives the second configuration information sent by the network device;

S320, the network device sends a reference signal to the terminal device by using a reference signal resource in the M reference signal resource set; correspondingly, the terminal device receives the M reference signal resource by the network device a reference signal transmitted by a reference signal resource in the set;

S330, the network device determines, according to the second parameter, the third parameter, and the second configuration information, a reporting mode of the terminal device, where the reporting mode is used to indicate channel quality information and/or the channel quality information. a number of bits, the second parameter is used to indicate that the spatial domain transmit filters corresponding to the P reference signal resources in each reference signal resource set are different, and the third parameter is used to indicate the M reference Whether the spatial domain transmission filter between the signal resource sets is the same;

S340, the terminal device determines, according to the second parameter, the third parameter, and the second configuration information, a reporting mode of the terminal device;

S350, the terminal device sends the channel quality information measured by the reference signal according to the reporting mode; and correspondingly, the network device receives the channel quality information sent by the terminal device according to the reporting mode.

Specifically, the network device may first configure, by using the second configuration information, the M reference signal resource sets, where each reference signal resource set includes P reference signal resources, that is, reference signal resources included in each reference signal resource set. The number of the reference signal resources is the same, and the set of M reference signal resources includes the reference signal resources used by the network device to send the reference signal to the terminal device. Then, the network device may send a reference signal to the terminal device by using the reference signal resource in the configured M reference signal resource sets, and the terminal device receives the reference signal, and measures the reference signal to obtain a measurement result. As described above, the terminal device can select the optimal Q channel quality information from the measurement result and report it to the network device.

In the embodiment of the present application, there are a second parameter and a third parameter, which are both known by the network device and the terminal device, and the second parameter is used to represent the P reference signal resources in each of the reference signal resource sets. The spatial domain transmit filters are different, in other words, the type of the M reference signal resource sets is of the "OFF" type. The third parameter is used to indicate whether the spatial domain transmission filter between the M reference signal resource sets is the same. Taking M=2 as an example, the two reference signal resource sets of the "OFF" type may be b1-b8 and b1-b8, or b1-b8 and b9-b16. It should be understood that the former indicates that the spatial domain transmission filter between the two reference signal resource sets is the same, and the latter indicates that the spatial domain transmission filters between the two reference signal resource sets are different. For b1-b8 and b1-b8, the terminal device only needs to report for 8 reference signal resources, and for b1-b8 and b9-b16, the terminal device needs to report for 16 reference signal resources, so different third The parameters affect the reporting mode of the terminal device.

The terminal device may determine the current reporting mode according to the second parameter, the third parameter, and the second configuration information, that is, determine the reported channel quality information, and further, the terminal device may determine the number of bits of the channel quality information. Different reporting modes correspond to different channel quality information selection methods, and in different reporting modes, the number of bits of channel quality information may be different. For the same reason, the network device can also determine the reporting mode of the terminal device, thereby determining the channel quality information selected by the terminal device, so as to accurately receive the channel quality information reported by the terminal device.

As an optional embodiment, the third parameter includes a repetition factor R of the M reference signal resource sets, where the repetition factor R is used to represent a number of reference signal resource set groups, and the reference signal resource set The group includes at least one reference signal resource set, and the spatial domain transmit filter between the at least one reference signal resource set is different, and the spatial transmit filter between the R reference signal resource set groups is the same, where R is An integer greater than or equal to 1 and less than or equal to M.

H is an integer greater than or equal to 1.

As an optional embodiment, when R is equal to M, the channel quality information includes an index of a first reference signal resource in any reference signal resource set;

When R is equal to 1, the channel quality information includes an index of a first reference signal resource in the M reference signal resource sets, or an index of a first reference signal resource set in the M reference signal resource sets, and the An index of the first reference signal resource in the first set of reference signal resources; and/or

When R is greater than 1 and less than M, the channel quality information includes an index of a first reference signal resource in the reference signal resource set, or an index of a first reference signal resource set in the reference signal resource set An index of the first reference signal resource in the first reference signal resource set.

It should be understood that the first reference signal resource index is the channel quality information of the optimal Q reference signals selected by the terminal device, and needs to be reported by the terminal device to the network device. At the time of reporting, if R=M, the terminal device can directly report the index of the first reference signal resource in any reference signal resource set, because the spatial domain transmission filter between the M reference signal resource sets is the same. The spatial domain transmit filters may be in the same order; if R=1, the terminal device may report the index of the first reference signal resource in the M reference signal resource sets, or first report the first reference where the first reference signal resource is located. The index of the signal resource set is further reported to the index of the first reference signal resource in the first reference signal resource set, which is not limited in this embodiment; if R>1 and R<M, the terminal device may directly report the first The index of the reference signal resource in the reference signal resource set group is such that the reporting overhead of the terminal device is reduced.

As an optional embodiment, when R is greater than or equal to 1, and is less than M, the channel quality information includes an index of the first reference signal resource in the M reference signal resource sets, or the M reference signals An index of the first set of reference signal resources in the set of resources and an index of the first reference signal resource in the first set of reference signal resources.

In this case, optionally, M is an integer multiple of R.

The present application is described in detail below in conjunction with a specific embodiment.

For example, the network device is configured with eight reference signal resource sets, and each of the eight reference signal resource sets includes eight reference signal resources, that is, the number of reference signal resources sent by the network device to the terminal device is 64. The repetition factor R can be 1, 2, 4 or 8.

When R=8, the reference signal resource index in the eight reference signal resource sets may be b1-b8, b1-b8, b1-b8, b1-b8, b1-b8, b1-b8, b1-b8, b1- B8, at this time, there are 8 reference signal resource set groups (set groups), and the terminal device reports channel quality information according to the index in the reference signal resource set, which requires 3 bits;

When R=4, the reference signal resource index in the eight reference signal resource sets may be b1-b8, b9-b16, b1-b8, b9-b16, b1-b8, b9-b16, b1-b8, b9- B16, at this time, there are 4 set groups, and the terminal device reports channel quality information according to the index of the set group, which requires 4 bits;

When R=1, the reference signal resource index in the eight reference signal resource sets may be b1-b8, b9-b16, b17-b24, b25-b32, b33-b40, b41-b48, b49-b56, b57- B64. At this time, there is one set group, and the terminal device reports channel quality information according to the index of the set group, which requires 6 bits.

In this way, under different repetition factors, the index of the reference signal resource reported by the terminal device and the number of used bits are different, which enables the terminal device to select the corresponding bit for reporting according to the actual situation, which is beneficial to save the reporting overhead of the terminal device. Thereby improving system performance.

In an optional embodiment, the third parameter includes a parameter of a first type or a parameter of a second type, where the first type is used to indicate P spatial domain transmission filtering between the M reference signal resource sets The second type is used to indicate that the P spatial domain transmit filters between the M reference signal resource sets are not identical.

Specifically, the first type can be represented by "type A" and the second type can be represented by "type B". In type A, the spatial domain transmit filters between the M reference signal resource sets are the same. Under type B, the spatial transmit filters between the M reference signal resource sets are not identical. For example, M=2, P=8. Under type A, the two reference signal resource sets are b1-b8 and b1-b8, respectively. Under type B, the two reference signal resource sets are b1-b8 and B9-b16. The terminal device may directly determine the type between the M reference signal resource sets according to the third parameter, thereby determining the channel quality information to be reported.
