Description

Data receiving method, data transmitting method, device and system

Technical Field

The present application relates to the field of communications, and in particular, to a data receiving method, a data sending method, a device, and a system.

Background

With the development of communication technology, the requirements for data receiving and transmitting of devices in the communication field are also higher and higher. In the fifth Generation mobile communication technology (5 th-Generation, 5G) being driven by the third Generation partnership project (3rd Generation Partnership Project,3GPP), the communication device needs to receive data from different beam directions, and may also receive reference signals for measurement.

In some cases, the reference signals and data may come from different beam directions, for example, as shown in fig. 1, the receiving device is a User Equipment (UE) that receives data and reference signals from three different beam directions on the current slot (slot), wherein a synchronization signal block (Synchronization Signal Block, SSB) 1 (a reference signal for measurement) is sent in beam direction 1, SSB2 and data are sent in beam direction 2, and SSB3 is sent in beam direction 3, wherein SSB1 and SSB3 come from different beam directions than the data in beam direction 2. The UE needs to receive the data and SSB sent by these Beam directions through its own receive Beam unit (Rx Beam 1).

Since the UE needs to receive data from beam direction 2, it also needs to measure different beam directions, e.g. beam directions 1-3, by receiving SSBs 1-3 to determine the channel quality between its own received beam unit and the different beam directions. It can be seen that the receiving device needs to have the capability to receive reference signals and data from different beam directions in order to compromise the measurement accuracy without affecting the reception of data from the serving cell.

Detailed Description

Embodiments of the present application are described below with reference to the accompanying drawings.

In the 5G standardization process being promoted by 3GPP, the communication device needs to receive data from different beam directions, where the data may include service data and reference signals for measurement. In this embodiment of the present application, the data may include control information such as physical downlink control channel (Physical Downlink Control Channel, PDCCH) information and traffic data such as physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) data. The Reference Signal is a Signal for measuring channel quality, and may include SSB, channel state information Reference Signal (CSI-RS), and the like.

The SSB here includes at least a synchronization signal for synchronization, such as a master synchronization signal, a slave synchronization signal; optionally, the SSB may also include a broadcast channel for secondary synchronization, such as a physical broadcast channel PBCH (Physical Broadcast Channel). The SSB may include a plurality of time domain symbols including the above-mentioned: the primary synchronization signal and the secondary synchronization signal optionally further comprise a symbol where the PBCH is located.

When the first device needs to receive reference signals from different beam directions simultaneously and the first device also needs to acquire data from the second device, the first device is difficult to receive the reference signals and the data simultaneously, or the first mode needs to discard part of the data to receive the reference signals; or in a second way not receiving reference signals from other beam directions but receiving data of the second device. For the first mode, decoding errors may be caused by discarded data portions when the first device decodes the received data; in the second mode, the measurement accuracy of the first device in the beam directions other than the beam direction from the second device is reduced, which may adversely affect the first device when it needs to switch to the other device. For example, to improve system performance under co-channel measurements, the base station typically does not configure a measurement GAP (GAP) for the UE making the co-channel measurements. The UE needs to measure reference signals from each of the different beam directions based on its own capabilities. How to measure the UE can ensure certain measurement accuracy without affecting the reception of the data packet of the serving cell is a problem which needs to be solved. Otherwise, the measurement accuracy is reduced, and cell switching based on the measurement result is affected; or to the reception of own downstream data.

Therefore, the embodiment of the application provides a data receiving method, a data sending method, a device and a system for receiving reference signals from multiple beam directions, and a rate matching mode of the reference signals and data which are required to be sent by a second device is configured according to indication information sent by a first device, so that the first device can acquire the reference signals from multiple beam directions under the condition that the reference signals from multiple beam directions are required to be received, the data sent by the second device can be received without being influenced, and the two aspects of measurement precision and data receiving are guaranteed.

In an embodiment of the application, a first device that needs to receive reference signals from different beam directions and a second device that needs to send reference signals and data to the first device are involved. The first device may comprise a transmitting device and the second device may comprise a receiving device. The first device and the second device may be various network elements having a transmission function, and may be, for example, a Base Station (BS), a relay device, a terminal device (Terminal Equipments, TE), an evolved Node B (eNB), an NR Base Station (gNB) in 5G, and the like. Wherein the TE may comprise a UE.

The second device is a device that transmits data to the first device. In some cases, a data connection may be established between the first device and the second device, where the data connection may be related to a scenario in which the embodiments of the present application are applied. The scenario to which the embodiments of the present application are applied may include a cellular link, and may also include an inter-Device-to-Device (D2D); but also to the backhaul link between base stations. In the cellular link, the first device may be a UE, and the second device may be a base station, for example, as shown in fig. 2a, where the UE and the base station communicate through an uplink and a downlink; in the D2D link, both the first device and the second device may be UEs, for example, as shown in fig. 2b, and the UE1 and the UE2 communicate through a sidelink (sidelink).

In the embodiment of the present application, the transmission resource may include a symbol, and the symbol may refer to a time domain symbol used for transmitting a reference signal, service data, and the like. At least one subband, bandwidth portion, carrier, spread-spectrum code channel, or one or more beam directions pointing to a particular spatial domain may be included in a symbol. One symbol may be a symbol in a multi-carrier system (i.e., a carrier unit including a plurality of frequency domains), or a symbol in a single carrier system or a symbol in a spread spectrum system. The carrier unit in the multi-carrier system may be a carrier unit of an orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) system, or may be a carrier unit of an OFDM system based on discrete fourier transform (Discrete Fourier Transform, DFT) spreading, which is not limited in the embodiment of the present application.

The beam (beam or beam forming) in the embodiment of the present application may be a spatial transmission waveform with a certain directivity formed by the first device by using a certain beam forming manner. The beam forming manner may be a beam formed based on an analog circuit, or a beam generated by precoding vectors or matrices based on a plurality of digital antenna ports, which is not limited in the embodiment of the present application. The beam has a certain spatial directivity, and the beam direction can be used to indicate the spatial pointing direction of the beam.

The beam direction may be a direction in which one device, e.g., the second device, transmits a beam, one device may have a plurality of beam directions, and the beam direction of one device may be changed. And a receive beam element of a device, such as a first device, may be an element for receiving a beam from a beam direction. The direction of the receive beam unit of one device may also be changed.

In the embodiment of the present application, the first device needs to receive the reference signals from different beam directions, and each beam direction in the different beam directions may respectively originate from different devices, where multiple beam directions may also originate from the same device. For example, in the case shown in fig. 1, the beam direction 1 and the beam direction 2 may both be directions in which the second device transmits the beam, i.e. both originate from the second device, and the data in the beam directions 1 and 2 may both be transmitted by the second device. Alternatively, beam directions 1-3 are the directions in which three different devices transmit beams, respectively.

Example 1

The present embodiment mainly describes, in connection with the first device and the second device, various manners of data reception and transmission when the first device needs to receive the reference signal from the multi-beam direction.

Next, a method for receiving multi-beam direction data and transmitting the data according to an embodiment of the present application is described with reference to fig. 3, where the method includes the following steps:

301: the first device sends to the second device information indicative of the number of beams receivable by the first device.

The number of receivable beams by the first device may embody the capability of the first device to receive beams. When the number of receivable beams of the first device is one, the first device can receive data and reference signals of one beam direction at the same time; when the number of receivable beams is plural, the first device may receive data and reference signals for plural beam directions simultaneously. The more the first device can receive the wave beam quantity at the same time, the stronger the capability of the first device for receiving the wave beam is reflected. Accordingly, the more powerful the first device is in receiving the beam, the more costly it is to get the first device.

Most of the first devices currently have low beam receiving capability, and it is not uncommon for a first device to be able to receive multiple beam direction data and reference signals simultaneously. Therefore, when facing a scene where a plurality of beam direction reference signals need to be received simultaneously, most of the first devices have difficulty in achieving both measurement accuracy and reception data.

Since the capability of different first devices to receive the beam may be different, it is not desirable to use a uniform rate matching scheme, which requires consideration of the first devices with lower capability to receive the beam. Therefore, the first device needs to report the indication information of the number of receivable beams of the first device to the second device, so that the second device can determine the corresponding rate matching mode according to different number of receivable beams in a targeted manner.

The indication information may include any one of the following:

the number of beams receivable by the first device, the beam capabilities receivable by the first device, or the rate matching manner supported by the first device.

If the indication information is the number of beams receivable by the first device, the indication information may directly represent the number of beams receivable by the first device, so that the second device may directly determine, through the indication information, the number of beams receivable by the first device at the same time, thereby selecting a corresponding rate matching manner to be applied to data sent to the first device.

If the indication information is the beam capability that the first device can receive, the first device and the second device may have a preset beam capability corresponding relationship, where the corresponding relationship includes the number of beams or the rate matching manner corresponding to different beam capabilities, for example, the capability 1 corresponds to FDM, the capability 2 corresponds to TDM, and the second device searches, according to the preset corresponding relationship and the beam capability provided in the indication information, the number of beams that the first device can simultaneously receive to determine the corresponding rate matching manner, or can directly find the rate matching manner corresponding to the counting capability, which is not limited herein.

If the indication information is a rate matching mode supported by the first device, the rate matching mode may be selected by the first device, and the selected mode may be based on an ability of the first device to receive a beam, or based on a rate matching mode supported by a specific application scenario dynamic change. For example, in the case where power consumption needs to be saved, the indication information that the first device, which originally can receive the plurality of beams, can send to the second device is TDM, so that the first device can only turn on one receiving beam unit to receive the reference signals from the plurality of beam directions, and turn off the remaining receiving beam units to save power consumption; when power consumption does not need to be saved, the indication information sent by the first device to the second device is FDM, so that data sent by the second device through the first beam direction is subjected to rate matching according to the FDM, and the first device can receive reference signals from multiple beam directions through multiple receiving beam units. In an alternative case, when the number of receivable beams of the first device is plural, the indication information sent by the first device may be a rate matching manner supported by the first device. If the rate matching mode supported by the first device in the indication information is TDM, the first device may configure the number of receivable beams of the first device to be one, so as to save power consumption.

The indication information may also include different possibilities in the same application scenario, for example, the first device may send, to the second device at a first time, indication information including the number of beams receivable by the first device or the beam capability receivable by the first device, then the data received through the first beam direction are all rate matching modes corresponding to the number of beams receivable by the first device or the beam capability receivable by the first device, at a second time after the first time, the first device may send, to the second device, according to its own needs, indication information including the rate matching modes supported by the first device, where the rate matching modes in the indication information may be different from the rate matching modes adopted by the second device for the data before the second time after the first time, and after the first device sends the indication information, the data received through the first beam direction are all rate matching modes in the indication information. For another example, the first device may first send, to the second device at a first time, indication information including a rate matching manner supported by the first device, and at a second time after the first time, the first device may send, to the second device, further according to its own needs, indication information of the number of beams receivable by the first device or beam capability receivable by the first device.

The indication information may include, in addition to the number of beams receivable by the first device, the beam capability receivable by the first device, or the rate matching mode supported by the first device, duration information, where the duration information is used to determine an applicable time of the rate matching mode supported by the first device in the indication information. The time length information can be preset for a period of time, can be preset for a plurality of periods of time, or can be preset for a plurality of periods of time with a periodic rule. When the second device receives the indication information with the duration information, the second device can adopt a rate matching mode corresponding to or indicated by the indication information to the data sent to the first device in a time period indicated by the duration information, and can determine the rate matching mode according to own requirements or other basis or not to perform rate matching on the data outside the time period indicated by the duration information. It should be noted that, when the indication information may include the duration information, if the first device has sent the indication information including the beam capability receivable by the first device to the second device before sending the indication information including the duration information to the second device, the second device performs rate matching on the data sent to the first device in a rate matching manner indicated by the indication information including the duration information within an applicable time indicated by the duration information. Corresponding to the rate matching mode corresponding to the indication information covering the receivable beam capability of the first device. And the second device can also adopt a rate matching mode corresponding to the indication information comprising the receivable beam capability of the first device for the data sent to the first device outside the using time indicated by the duration information.

302: and the second equipment determines a rate matching mode for the data according to the indication information.

In the embodiment of the application, rate matching refers to the operation of configuring and adjusting transmission resources occupied by reference signals and data when the transmission resources occupied by the reference signals and the transmission resources occupied by the data overlap in data transmission. That is, the transmission resources of the reference signal overlap with the transmission resources of the data prior to rate matching according to the rate matching scheme.

While the rate matching paradigm refers to a specific implementation of rate matching, there are many ways in which rate matching may be performed, and may include, for example, frequency division multiplexing (Frequency Division Multiplexing, FDM) and time division multiplexing (Time Division Multiplexing, TDM). When the rate matching manner of FDM is used, the transmission resources occupied by the reference signal include data, for example, as shown in fig. 4a, where the reference signal and the data are on different subcarriers with the same symbol. In the case of using the TDM rate matching method, the reference signal and the data occupy different time domain transmission symbols, for example, as shown in fig. 4b, the symbol occupied by the reference signal is not mapped with a data subcarrier, and the data is only transmitted on other symbols except for the symbol occupied by the reference signal. Other possibilities for transmission resources occupied by reference signals and data are also possible, such as shown in fig. 4c, 4 d.

These two rate matching approaches have different spectral efficiencies. Under FDM, the second device can simultaneously transmit data and reference signals on the same symbol, so that the spectrum efficiency can be maximized; in TDM, since the reference signal and the data occupy different time domain transmission symbols, in order to transmit the reference signal, the second device needs to discard a part of data originally carried in the data subcarriers on the reference signal symbol, and use the part of subcarriers to transmit the reference signal, or cannot transmit the service data by using the part of subcarriers, which reduces the spectrum efficiency.

Since the time domain symbols occupied by the reference signal also include data in the case of FDM, the first device needs to keep receiving data in the beam direction of the second device in order to avoid discarding data. If the first device has low beam receiving capability, for example, when only data and reference signals in one beam direction can be received simultaneously, the second device does not perform rate matching on the data in the FDM manner, which would cause that it is difficult for the first device to receive the reference signals and the data simultaneously.

Therefore, when the second device determines that the number of receivable beams of the first device is one, the corresponding rate matching mode can be determined to be TDM, in the case of TDM, no data subcarrier exists in the time domain symbol occupied by the reference signal, the first device can change the receiving direction of the self-receiving beam unit on the transmission resource so as to receive the reference signals in other beam directions, and the parallel receiving capability of the first device on the reference signals and data from different beam directions is improved.

When the first device has higher beam receiving capability, for example, can receive data and reference signals in multiple beam directions at the same time, the first device can receive the reference signals from other beam directions through other beam receiving units while one beam receiving unit keeps receiving the beam direction data and the reference signals of the second device, so when the second device determines that the number of receivable beams of the first device is multiple, the corresponding determination of the rate matching mode of the data is FDM with higher frequency spectrum efficiency, and the utilization rate of system resources is improved.

When the second device determines a corresponding rate matching mode according to the capacity of the first device for receiving the wave beam, the second device sets transmission resources occupied by the reference signal and the data in the data by adopting the rate matching mode or performs rate matching on the data by adopting the rate matching mode when transmitting the data to the first device.

303: the first device obtains data from the first beam direction and determines a rate matching manner of the data based on the number of beams receivable by the first device. The first beam direction may be one of a plurality of beam directions received by the first device and be a beam direction of the second device.

The manner in which the data acquired by the first device from the first beam direction is rate matched may be changed accordingly in connection with the different possibilities that the indication information can comprise in step 301.

The first device may acquire, in addition to the data from the second device, an indication information sent by the second device from the second device, where the indication information may include an applicable time of the rate matching mode supported by the first device. That is, although the first device informs the second device of the capability of receiving the beam by itself, the second device may determine whether or not the data transmitted to the first device can be rate-matched according to the rate matching method corresponding to the capability of receiving the beam by the first device, or may determine the time of using the rate matching method when it is determined to use the rate matching method corresponding to the capability of receiving the beam by the first device, and when it is determined to use the applicable time of the rate matching method, the second device may inform the first device of the applicable time by the above-mentioned indication information, so that the first device can know what rate matching method is used to decode the data received from the second device in what time period.

It can be seen that the first device may send, to the second device, indication information of the number of receivable beams of itself, determine, by the second device sending data to the first device, which rate matching mode to use for rate matching data to be sent, and send the data to the first device from the first beam direction, where transmission resources of the reference signal overlap with transmission resources of the data before rate matching according to the rate matching mode. That is, before rate matching is performed on the transmitted data, the time-frequency resource where the transmitted data is transmitted and the time-frequency resource where the reference signal is transmitted overlap with the transmission carrier of the data on all or part of the symbols where the reference signal is located on the subcarriers where the reference signal is located. The UE does not receive two completely different signals on the same subcarrier and the second device needs to rate match on these overlapping subcarriers or time domain symbols. The relation between the data from the first beam direction and the transmission resources occupied by the reference signal is adapted to the capability of the first device to receive the number of beams, so that the first device has the possibility to acquire the reference signal from the other beam directions when acquiring data through the first beam direction. Therefore, under the scene that the reference signals from a plurality of beam directions are required to be received, the first equipment can acquire the reference signals from the plurality of beam directions, and can not influence the receiving of the data sent from the second equipment, so that the two aspects of measurement accuracy and data receiving are both ensured.

In the case that the indication information includes a rate matching mode that can be supported by the first device, in a scenario that the indication information needs to receive reference signals from multiple beam directions, the rate matching mode that the first device acquires data from the first beam direction is that the first device can support the first device in the scenario, so that the first device can acquire the reference signals from the multiple beam directions, and can also not influence the reception of data sent from the second device, thereby realizing both measurement accuracy and data reception.

After step 303, the first device will need to receive reference signals from different beam directions. Next, how the first device can receive data from multiple beam directions will be described in connection with the difference in the manner in which the data acquired from the first beam direction is rate matched.

For the case where the rate matching manner is FDM:

in this case, the first device belongs to a device with a high beam receiving capability. The first device may receive a plurality of beam directions, and the first device includes at least a first receive beam unit and a second receive beam unit.

For step 303, the first device may use one of its receive beam units, such as the first receive beam unit, to receive data sent from the second device from the first beam direction, where the reference signal and the traffic signal are rate matched in an FDM manner, so the first device needs to keep the first receive beam unit from receiving the data so as not to discard the traffic data. And the first device may also receive reference signals transmitted from a second beam direction, which is one of the plurality of beam directions received by the first device, through other receive beam units, such as a second receive beam unit.

For example, as shown in fig. 5, the first device includes two receiving Beam units, namely Rx Beam1 (first receiving Beam unit) and Rx Beam2 (second receiving Beam unit), the first device receives data in Beam direction 2 (first Beam direction) through Rx Beam1, the data is sent by the second device, and includes PDSCH and SSB2, where PDSCH and SSB2 are rate-matched through FDM. The first device, upon receiving data from Beam direction 2, may receive a reference signal from Beam direction 3 or Beam direction 1 through Rx Beam 2.

Therefore, the first device can receive the reference signals in different beam directions, and simultaneously can receive the service data sent by the second device, and the spectrum efficiency is maximized.

For the case where the rate matching manner is TDM:

in this case the first device belongs to a device with a weaker reception beam capability. The number of receivable beams is one for the first device, which comprises one receiving beam unit.

The first device acquires data from a first beam direction through a beam receiving unit on transmission resources occupied by the data.

The first device may also receive, via the receive beam unit, a reference signal transmitted from a second beam direction on a transmission resource occupied by the reference signal, the second beam direction being one of a plurality of beam directions received by the first device.

In the same-frequency measurement scenario, the device sending the reference signal will set measurement windows uniformly, and the transmission resource position of the reference signal in each measurement window can be determined. The first device may obtain a reference signal for measurement in a transmission resource where the measurement window is located. For example, fig. 6 shows different measurement windows configured by a base station transmitting a reference signal for a UE. In the transmission resource where the measurement window 1 is located, the first device may acquire the reference signal from the first beam direction through its own beam receiving unit, in the transmission resource where the measurement window 2 is located, the first device may adjust the receiving angle of the beam receiving unit, receive the reference signal from the second beam direction, and so on. Thereby improving the capability of the first equipment for both the reference signal and the service data.

It should be noted that the second beam direction may be a direction in which the second device transmits a beam, or may be a direction in which the third device transmits a beam.

Example two

This embodiment describes an alternative way of determining the rate matching, which may be implemented on the basis of the first embodiment or may be implemented off the basis of the first embodiment.

The first device may obtain matching mode information from the second device, the matching mode information indicating a rate matching mode of the data. I.e. the first device knows by means of the matching means information in which rate matching means the data acquired from the first beam direction is rate matched. Thus, when the first device acquires the data from the first beam direction, the first device can decode the data according to the rate matching mode indicated by the matching mode information because the rate matching mode of the data is the rate matching mode indicated by the matching mode information.

The rate matching mode indicated by the matching mode information is determined by the second device according to the position of the first device, the first beam direction and a third beam direction, wherein the third beam direction is one of a plurality of beam directions received by the first device, and a reference signal is sent in the third beam direction.

When determining the rate matching mode, the second device needs to consider the position of the first device, the angle between the first beam direction and the third beam direction, and when the angle is smaller, for example, when reaching Quasi Co-Location (QCL), the first beam direction and the third beam direction are the same or similar, and relative to the first device, the first beam direction and the third beam direction can be regarded as one beam direction, so that the second device can determine the corresponding rate matching mode, for example, FDM. When the included angle is larger, the first beam direction and the third beam direction are different beam directions relative to the first device, so that the second device can determine a corresponding rate matching mode, such as TDM. This scheme of determining the rate matching manner may in some cases help the first device with lower beam receiving capability to improve the spectral efficiency, for example, optionally, the number of receivable beams of the first device is one. In a scenario where reference signals from multiple beam directions need to be received, the second device typically performs TDM rate matching on the data sent to the first device, so as to help the first device achieve both measurement accuracy and data reception. When the first device moves to a position such that the included angle between the first beam direction and the third beam direction is smaller relative to the position of the first device, the second device can adjust the rate matching mode of data sent to the first device to be FDM, and inform the first device through the matching mode information, so that the first device can receive reference signals from the first beam direction and the third beam direction at the position through one beam receiving unit, and the data from the first beam direction can not be discarded, thereby improving the frequency spectrum efficiency.

Example III

The present embodiment mainly describes, in connection with the first device and the second device, various manners of data reception and transmission when the first device needs to receive the reference signal from the multi-beam direction. In this embodiment, the second device does not determine a rate matching manner suitable for the beam receiving capability of the first device according to the beam receiving capability of the first device, but adopts a manner of configuring measurement GAPs (GAPs) for the first devices with different beam receiving capabilities, so that the first device can acquire reference signals for measurement from multiple beam directions on transmission resources indicated by the measurement GAPs.

Fig. 7 is a method flowchart of a data transmission method according to an embodiment of the present application, where the method includes:

701: the first device sends information indicating the number of receivable beams of the first device to the second device, which is the device that sends data to the first device.

The indication information includes any one of the following:

the number of beams receivable by the first device or the beam capabilities receivable by the first device.

The description of the indication information may be referred to the description in the first embodiment, and will not be repeated here.

702: if the second device determines that the number of receivable beams of the first device is one according to the indication information, the second device configures configuration information of the measurement gap for the first device.

703: and if the second equipment determines that the number of the receivable beams of the first equipment is multiple according to the indication information, the second equipment does not configure a measurement gap for the first equipment.

It can be seen that after the second device obtains the indication information, the receivable beam capability of the first device can be determined, and whether to configure the measurement gap for the first device can be determined according to the receivable beam capability of the first device. When the number of receivable beams of the first device is plural, the plural receiving beam units of the first device may receive the reference signals from different beam directions, so that the measurement gap may not be configured for the first device. When the number of receivable beams of the first device is one, the first device has only one beam receiving unit, and when the reference signals from different beam directions are received, it is difficult to achieve both measurement accuracy and reception data, so that a measurement gap can be configured for the first device. So after execution 702 is complete, execution 704 may be performed.

Wherein 703 is an optional implementation step.

704: the second device sends configuration information and a reference signal to the first device from the beam direction of the second device, and transmission resources occupied by the reference signal are transmission resources corresponding to the measurement gap.

705: the first device obtains reference signals for measurement from a plurality of beam directions on transmission resources indicated by the configuration information.

The configuration information may indicate whether the measurement gap is configured. Therefore, when the number of receivable beams of the first device is one, the first device can determine that the second device configures a measurement gap for the first device through the configuration information acquired from the second device, and the measurement gap does not transmit data to the first device through the first beam direction, so that the first device can acquire reference signals for measurement from a plurality of beam directions on a transmission resource of the measurement gap, and does not discard the data from the first beam direction.

Optionally, the second device may further determine, when determining that the measurement gap is configured for the first device, an application time for using the measurement gap according to a requirement, and after determining the application time, the second device may carry the duration information through configuration information, and send the configuration information to the first device, where the duration information is information indicating a time length for which the measurement gap configuration is effective. So that the first device knows in what time period to acquire reference signals for a plurality of beam directions through the measurement gap.

When the number of receivable beams is plural, optionally, the first device may also obtain configuration information from the second device, indicating that the second device does not configure the measurement gap for the first device.

It can be seen that the first device may send, by the second device, indication information of the number of self-receivable beams, from which indication information the second device sending data to the first device determines whether to configure configuration information of the measurement gap for the first device. Since the number of receivable beam directions by the first device is one, the first device can acquire the configuration information from the second device. Since no data is present on the transmission resource indicated by the configuration information, the first device may be able to acquire reference signals for measurement from multiple beam directions without receiving data from the second device on the transmission resource. Therefore, under the scene that the reference signals from a plurality of beam directions are required to be received, the first equipment can acquire the reference signals from the plurality of beam directions, and can not influence the receiving of the data sent from the second equipment, so that the two aspects of measurement accuracy and data receiving are both ensured.

Example IV

Fig. 8 is a method flowchart of a data transmission method according to an embodiment of the present application, where the method includes:

801: the second device determines indication information according to preset conditions, wherein the indication information is used for indicating a rate matching mode adopted by data sent by the second device, and the second device is a device for sending the data to the first device.

In this embodiment, the second device may determine, according to a preset condition, what rate matching mode is used for rate matching of the data sent to the first device, where the preset condition may be related to an environment, a requirement, a state, and a situation in which the second device is located. The preset condition may include, for example, a priority level of data to be transmitted to the first device or a power consumption level of the second device. Optionally, the rate matching manner for the data includes FDM or TDM. For example, the second device may use FDM when the priority of the data to be transmitted is higher, to reduce the probability of discarding the data by the first device, and TDM when the priority of the data to be transmitted is lower, so that the first device may have a chance to receive the reference signals from other beam directions.

802: the second device sends the indication information to the first device;

The second device may send the rate-matching pattern determined in this way to the first device via the indication information, which is different from the indication information mentioned in the previous embodiments.

803: the first device obtains the data from the second device, and determines a rate matching mode of the data according to the indication information, wherein transmission resources of a reference signal overlap with transmission resources of the data before rate matching is performed according to the rate matching mode.

For data received from the second device, the first device will decode the data in a rate matching manner indicated in the indication information obtained from the second device.

The first device may receive the data from a target beam direction, the target beam direction being a direction of a transmit beam of the second device, the target beam direction being one of a plurality of beam directions received by the first device.

The first device may obtain, in addition to the indication information from the second device, duration information from the second device, where the duration information includes a length of time for indicating that the speed matching mode is effective in the foregoing indication information.

The time length indicated by the duration information may be determined by the second device according to the requirement, i.e. it is clear in which time length the rate matching mode indicated in the indication information is used. After the first device acquires the duration information, it can be clear at which time duration the content adopts the rate matching mode indicated by the indication information to decode the data received from the second device.
