Taking a distributed antenna system in a base station as an example, when the base station transmits channel state information reference signals (Channel State In formation-Reference Signals, CSI-RS) through the distributed antenna system, one multi-port CSI-RS may be mapped to multiple antenna ports (one antenna port corresponds to one antenna unit), or one single-port CSI-RS may be mapped to one antenna port, and multiple single-port CSI-RS may be mapped to multiple antenna ports. The User Equipment (UE) may measure CSI-RS transmitted by the base station and report measurement results (e.g., CSI including channel Rank Index (RI), precoding matrix Index (Precoding Matrix Index, PMI), and channel quality information (Channel Quality Index, CQI)) to the base station.

The measurement configuration method according to the embodiment of the present invention is described below with reference to fig. 2. Fig. 2 is a flow chart of a measurement configuration method according to an embodiment of the present invention, as shown in fig. 2, the measurement configuration method includes S201 and S202:

s201, the network equipment sends measurement configuration information to the user equipment UE.

The measurement configuration information is used for indicating N pieces of resource information, the N pieces of resource information are the resource information adopted by the network equipment for transmitting the reference signal, and N is a positive integer.

It should be noted that, M antenna units are provided in the network device, where each of the M antenna units may be used for the network device to send a reference signal, and one resource information may correspond to one antenna unit. In the case where the distributed antenna system in the network device is an oversized distributed system, M may be much larger than N.

In the embodiment of the present invention, one antenna unit may correspond to one physical antenna, or one antenna unit may also correspond to a plurality of physical antennas. The plurality of physical antennas corresponding to one antenna unit may be physical antennas with adjacent positions, or may be physical antennas with non-adjacent positions, which is not particularly limited in the embodiment of the present invention.

It may be appreciated that in the embodiment of the present invention, the network device may indicate to the UE to measure the reference signals sent on a part of the M antenna elements by measuring the configuration information.

For example, in the embodiment of the present invention, the reference signal may also be referred to as a pilot signal, for example, a reference signal CSI-RS, and may also be referred to as a CSI-RS pilot.

The measurement configuration information may further include time domain resource information, frequency domain resource information, and the like for transmitting the reference signal.

The measurement configuration information may be one information, or N pieces of information, and in the case of multiple pieces of information, the measurement configuration information may be transmitted at one time or may be transmitted in multiple times, which is not particularly limited in the embodiment of the present invention.

S202, the UE receives measurement configuration information sent by the network equipment.

It may be appreciated that after receiving measurement configuration information sent by the network device, the UE may determine N pieces of resource information employed by the network device to send the reference signal according to the measurement configuration information, and then the UE may measure the reference signal sent on the corresponding antenna unit based on the N pieces of resource information. The number of antenna units for the UE to specifically measure the reference signal may be less than or equal to N (for example, P in the following embodiments), that is, the UE may measure the reference signal sent on N antenna units at most, which will be described in detail in the following embodiments, and will not be described in detail herein.

In the measurement configuration method provided by the embodiment of the invention, the network equipment can send the measurement configuration information to the UE so as to be used for indicating the network equipment to send N pieces of resource information of the reference signal, so that the UE can determine the resource information of the measurement reference signal according to the measurement configuration information, and the UE can further carry out measurement.

Optionally, in an embodiment of the present invention, in a possible implementation manner, the measurement configuration information may include one CSI-RS resource, where the one CSI-RS resource may correspond to N port numbers, and in this implementation manner, the N resource information is the N port numbers.

Specifically, one port number is mapped to one antenna unit, i.e., the above-mentioned N port numbers are mapped to N antenna units. The port number corresponding to an antenna unit may be a logical port number corresponding to the antenna unit.

That is, the UE may measure the reference signals transmitted on the antenna units to which the port numbers are mapped based on the N port numbers indicated in the measurement configuration information transmitted by the network device.

In another possible implementation manner, the measurement configuration information may include N CSI-RS resources, where each CSI-RS resource corresponds to a port number, and the N resource information is the N CSI-RS resources.

Specifically, one CSI-RS resource is mapped to one antenna unit, i.e., the above-mentioned N CSI-RS resources are mapped to N antenna units. Wherein each CSI-RS resource map contains a port number.

That is, the UE may measure the reference signal transmitted on the antenna unit to which the CSI-RS resource is mapped based on the N CSI-RS resources indicated in the measurement configuration information transmitted by the network device.

Fig. 3 is a schematic diagram of resource information provided by the embodiment of the present invention, where 12 physical antennas (12 inclined black rectangles) are shown in the figure, and one antenna unit includes 1 physical antenna, where n=8, as shown in (a) in fig. 3, a network device may configure CSI-RS resources of 8 ports according to a configuration manner shown in (a) in fig. 3, where the first antenna unit corresponds to CSI-RS port 1, the second antenna unit corresponds to CSI-RS port 2, the third antenna unit corresponds to CSI-RS port 3, the fourth antenna unit corresponds to CSI-RS port 4, the fifth antenna unit corresponds to CSI-RS port 5, the sixth antenna unit corresponds to CSI-RS port 6, the seventh antenna unit corresponds to CSI-RS port 7, the eighth antenna unit corresponds to CSI-RS port 8, the ninth antenna unit corresponds to CSI-RS port 1, the tenth antenna unit corresponds to CSI-RS port 2, the eleventh antenna unit corresponds to CSI-RS port 3, and the twelfth antenna unit corresponds to CSI-RS port 4. The antenna elements, not shown, continue to correspond to the corresponding CSI-RS port numbers in the above order in turn. As shown in (b) of fig. 3, the network device may configure 8 CSI-RS resources with single ports according to the configuration manner shown in (a) of fig. 3, where the first antenna unit corresponds to CSI-RS resource 1, the second antenna unit corresponds to CSI-RS resource 2, the third antenna unit corresponds to CSI-RS resource 3, the fourth antenna unit corresponds to CSI-RS resource 4, the fifth antenna unit corresponds to CSI-RS resource 5, the sixth antenna unit corresponds to CSI-RS resource 6, the seventh antenna unit corresponds to CSI-RS resource 7, the eighth antenna unit corresponds to CSI-RS resource 8, the ninth antenna unit corresponds to CSI-RS resource 1, the tenth antenna unit corresponds to CSI-RS resource 2, the eleventh antenna unit corresponds to CSI-RS resource 3, and the twelfth antenna unit corresponds to CSI-RS resource 4. And the antenna units which are not shown continue to correspond to the corresponding CSI-RS resources in sequence according to the sequence.

Based on the scheme, the network equipment can configure one CSI-RS resource for the UE through measuring the configuration information, the one CSI-RS resource corresponds to N port numbers, so that the UE can measure reference signals on N antenna units corresponding to the N port numbers in the CSI-RS resource, and can configure N CSI-RS resources for the UE through measuring the configuration information, each CSI-RS resource corresponds to one port number respectively, and the UE can measure the reference signals on N antenna units corresponding to the N CSI-RS resources.

Optionally, in the embodiment of the present invention, the N pieces of resource information are specific resource information adopted by the network device to send the reference signal through M antenna units in the network device, where M is a positive integer, and N < M.

It will be appreciated that the network devices may employ the same resource information on different antenna elements, i.e. the network devices may multiplex the same resource information.

In case the resource information is a port number, the network device may use the same port number on different antenna units, i.e. the network device may multiplex the same port number. In the case that the resource information is a CSI-RS resource, the network device may use the same CSI-RS resource on different antenna units, i.e. the network device may multiplex the same CSI-RS resource.

Based on the scheme, the network device may include M antenna units, where the N pieces of resource information may be resource information (N may be smaller than M) used by the network device to transmit reference signals through the M antenna units in the network device, that is, in a process of measuring the reference signals by the UE, the UE may measure reference signals corresponding to the N pieces of resource information at most, that is, may measure reference signals transmitted on the N antenna units. If the network device includes an oversized distributed antenna system, that is, if M is far greater than N, on one hand, since the UE can measure the reference signals sent on part of the antenna units, it is not necessary to measure the reference signals sent on all the antenna units, so that the number of reference signals measured by the UE can be reduced, the complexity of calculating the measurement result by the UE is reduced, and the overhead of reporting the measurement result by the UE is also small. On the other hand, the network device can adopt the same resource information on different antenna units, namely, the network device can multiplex the same resource information, so that the cost of the resource information adopted by the network device for transmitting the reference signal can be reduced.

Optionally, in an embodiment of the present invention, each of the M antenna units corresponds to one resource information of the N resource information.

That is, each of the M antenna elements corresponds to the same one of the N resource information, respectively.

For example, in the case where the resource information is a port number, each of the M antenna units corresponds to one of the N port numbers, respectively. That is, there are at least two antenna elements corresponding to the same port number. And under the condition that the resource information is the CSI-RS resource, each antenna unit in the M antenna units corresponds to the N CSI-RS resources respectively. That is, there are at least two antenna elements corresponding to the same CSI-RS resource.

In connection with fig. 3 (a), the first and ninth antenna elements shown in the drawing multiplex CSI-RS ports 1, the second and tenth antenna elements multiplex CSI-RS ports 2, the third and eleventh antenna elements multiplex CSI-RS ports 3, and the fourth and twelfth antenna elements multiplex CSI-RS ports 4. In connection with (b) of fig. 3, a first antenna unit and a ninth antenna unit shown in the drawing multiplex CSI-RS resource 1, a second antenna unit and a tenth antenna unit multiplex CSI-RS resource 2, a third antenna unit and an eleventh antenna unit multiplex CSI-RS resource 3, and a fourth antenna unit and a twelfth antenna unit multiplex CSI-RS resource 4.

Optionally, in the embodiment of the present invention, a distance between any two antenna units corresponding to the same resource information in the N pieces of resource information in the M antenna units is greater than or equal to a distance threshold.

Based on the scheme, the network device can repeatedly use a plurality of antenna units in M antenna units to map the same resource information in N resource information, so that the UE only measures the reference signals sent by the antenna units, which are relatively close to the UE, in the process of measuring the reference signals.

Optionally, in an embodiment of the present invention, the M antenna elements include K antenna element groups, each antenna element group includes at least one antenna element, and in each antenna element group, different antenna elements correspond to different resource information.

Wherein the K antenna element groups comprise X first antenna element groups and (K-X) second antenna element groups; the number of the antenna units in each first antenna unit group is smaller than N, the number of the antenna units in each second antenna unit group is equal to N, and K and X are positive integers.

It should be noted that, in the embodiment of the present invention, X may be equal to 0, that is, the number of antenna elements in each of the K antenna element groups is equal to N, that is, M is an integer multiple of N.

Illustratively, in the case where the resource information is a port number, it is assumed that m=100, n=8. The network device may include 100 antenna elements, the network device configures 8-port CSI-RS resources, one 8-port CSI-RS resource may correspond to 8 antenna elements, and if the antenna elements are configured in order from small to large, the 1 st group of antenna elements to the 12 th group of antenna elements include 8 antenna elements, and the 8 antenna elements in each group of antenna elements correspond to port 1, port 2, port 3, port 4, port 5, port 6, port 7 and port 8. The 13 th group of antenna elements includes 4 antenna elements (i.e., antenna element 97 may correspond to port 1, antenna element 98 may correspond to port 2, antenna element 99 may correspond to port 3, and antenna element 100 may correspond to port 4); i.e. x=1 and is group 13. Of course, if the antenna unit numbers are configured in order from large to small, the 1 st group of antenna units includes 4 antenna units (i.e., antenna unit 1 may correspond to port 4, antenna unit 2 may correspond to port 3, antenna unit 3 may correspond to port 2, antenna unit 4 may correspond to port 1), and the 2 nd group of antenna units to 13 th group of antenna units includes 8 antenna units; i.e. x=1 and is group 1.

Illustratively, in the case where the resource information is CSI-RS resources, it is assumed that m=100 and n=8. The network device may include 100 antenna units, the network device configures 8 CSI-RS resources with single ports, each CSI-RS resource with single port may correspond to one antenna unit, and if the antenna units are configured in order from small to large according to the number of the antenna units, the 1 st group of antenna units to the 12 th group of antenna units include 8 antenna units, and the 8 antenna units in each group of antenna units correspond to CSI-RS resource 1, CSI-RS resource 2, CSI-RS resource 3, CSI-RS resource 4, CSI-RS resource 5, CSI-RS resource 6, CSI-RS resource 7 and CSI-RS resource 8. The 13 th group of antenna elements includes 4 antenna elements (i.e., antenna element 97 may correspond to CSI-RS resource 1, antenna element 98 may correspond to CSI-RS resource 2, antenna element 99 may correspond to CSI-RS resource 3, and antenna element 100 may correspond to CSI-RS resource 4); i.e. x=1 and is group 13. Of course, if the antenna unit numbers are configured in sequence from large to small, the 1 st group of antenna units includes 4 antenna units (i.e., antenna unit 1 may correspond to CSI-RS resource 4, antenna unit 2 may correspond to CSI-RS resource 3, antenna unit 3 may correspond to CSI-RS resource 2, and antenna unit 4 may correspond to CSI-RS resource 1), and the 2 nd to 13 th groups of antenna units include 8 antenna units; i.e. x=1 and is group 1.

It should be noted that, of course, the network device may be configured not in the order of the antenna unit numbers, and X may be any value configured by the network device.

It should be noted that, in the above example, the antenna element groups are merely divided in order, that is, the number of antenna elements in the last group or the first group is smaller than N, and in practical application, the number of antenna elements in the multiple antenna element groups may be configured to be smaller than N, which is not limited in particular in the embodiment of the present invention.

The time domain resource and the frequency domain resource of the reference signal transmitted on different antenna units corresponding to the same resource information may be the same or different.

It should be noted that, when the time domain resource and the frequency domain resource of the reference signal transmitted on different antenna units of the same resource information are the same, the overhead of the network device for transmitting the reference signal can be reduced compared with the case of transmitting the reference signal by using different time-frequency domain resources.

Based on the scheme, M antenna units in the network equipment can be divided into K groups, and the K groups of antenna units can comprise antenna unit groups with the number of the antenna units smaller than N, namely the embodiment of the invention does not limit the multiple relation between the number of the antenna units in the network equipment and N pieces of resource information, and can be integer multiple or not integer multiple, so that the network equipment can flexibly configure the relation between the antenna units and the resource information.

Optionally, in an embodiment of the present invention, X is configured for the network device or predefined for the protocol.

It should be noted that in the embodiment of the present invention, X may be configured neither for the network device nor predefined for the protocol.

For example, X may also be determined for the UE according to parameters configured by the network device. For example, m=100, n=8, if the UE determines that the network device configures the resource information according to the order of the antenna unit numbers from small to large, X determined by the UE may be 1 and be the 13 th group of antenna units; if the UE determines that the network device configures the resource information according to the order of the antenna unit numbers from large to small, X determined by the UE may be 1 and be the 1 st group of antenna units.

Based on this scheme, the network device may configure or predefine a value of X for the UE, indicating which antenna element groups of the UE have a number of antenna elements less than N.

Optionally, the measurement configuration method provided in the embodiment of the present invention may further include S203:

s203, the network device indicates the first value P to the UE.

And P is used for indicating the quantity of the resource information corresponding to the reference signal to be measured by the UE in the N resource information, wherein P is a positive integer, and P is less than or equal to N.

For the "resource information corresponding to the reference signal" described above, the UE measures the reference signal transmitted on the antenna unit corresponding to the resource information, for example, the reference signal transmitted on the antenna unit corresponding to the port number measured by the UE, or the reference signal transmitted on the antenna unit corresponding to the CSI-RS resource measured by the UE.

Specifically, the network device may configure the first value P to the UE through semi-static configuration, configure the first value P to the UE through static configuration, or may indicate the first value P to the UE through dynamic signaling.

For example, the UE may select, from the N pieces of resource information, resource information corresponding to H reference signals with the strongest signal strength by measuring signal strength according to P indicated by the network device. Typically, the signal strength of the reference signal transmitted by the nearest H antenna elements is the strongest.

It should be noted that, the network device may determine P antenna elements nearest to the UE according to the location of the UE or by measuring the network device through an uplink channel or a signal of the UE, and the network device may also configure P port numbers for the UE.

Optionally, the network device may carry P in the measurement configuration information when sending the measurement configuration information to the UE, or the network device may indicate the first value P to the UE after or before S201, which is not limited by the configuration timing of P in the embodiment of the present invention.

Based on the scheme, the network device indicates the first value P to the UE, and the network device can indicate the number of the resource information corresponding to the measurement reference signal in the N resource information to the UE, so that the UE can measure the reference signal sent on the antenna unit corresponding to part or all of the N resource information.

Optionally, the measurement configuration method provided in the embodiment of the present invention may further include S204:

s204, the network equipment indicates the first initial resource information to the UE.

The first initial resource information is initial resource information of the reference signal to be measured by the UE in the N pieces of resource information.

Specifically, the network device may configure the first initial resource information to the UE through semi-static configuration, configure the first initial resource information to the UE through static configuration, and may also indicate the first initial resource information to the UE through dynamic signaling.

It should be noted that, if the UE determines the first initial resource information according to the indication of the network device, the UE may measure the reference signals corresponding to the H initial resource information by using the first initial resource information as the initial resource information.

Specifically, if the network device indicates the first value P to the UE, the UE may determine H pieces of resource information (h=p) according to the first starting resource information and the first value P. If the network device does not indicate the first value P to the UE, the UE may determine H resource information according to the first starting resource information and other information (e.g., signal strength of the reference signal, etc.).

The first initial resource information may be a start port number or a start CSI-RS resource. In combination with (a) in fig. 3, the network device may indicate that the CSI-RS port 2 is an initial CSI-RS port number, and if the network device further indicates p=4, the UE may determine that reference signals sent on the 4 antenna units corresponding to the CSI-RS port 2, the CSI-RS port 3, the CSI-RS port 4, and the CSI-RS port 5 are reference signals to be measured. In combination with (b) in fig. 3, the network device may indicate that the CSI-RS resource 2 is an initial CSI-RS resource, and if the network device further indicates p=4, the UE may determine that reference signals sent on the 4 antenna units corresponding to the CSI-RS resource 2, the CSI-RS resource 3, the CSI-RS resource 4, and the CSI-RS resource 5 are reference signals to be measured.

Optionally, the network device may carry the first initial resource information in the measurement configuration information when sending the measurement configuration information to the UE, or the network device may indicate the first initial resource information P to the UE after or before S201.

Based on the scheme, the network device may further indicate first initial resource information to the UE, and the UE may determine P pieces of resource information to be measured according to the first initial resource information, so as to measure reference signals corresponding to the P pieces of resource information.

Optionally, as shown in fig. 4, the measurement configuration method provided in the embodiment of the present invention may further include S205 and S206 described below after S202:

s205, the UE measures the reference signals corresponding to H pieces of resource information in the N pieces of resource information to obtain a measurement result.

Wherein H is a positive integer, and H is less than or equal to N.

Specifically, the manner in which the UE measures the reference signals corresponding to the H resource information may refer to a conventional measurement manner, which is not specifically described in the embodiments of the present invention.

Optionally, in the embodiment of the present invention, the second value H is a first value P indicated by the network device, or is the number of resource information corresponding to the UE measurement reference signal determined from the N pieces of resource information by the UE; the initial resource information in the H resource information is configured by the network equipment, indicated by the network equipment or determined by the UE from the N resource information.

That is, in the embodiment of the present invention, S205 and S206 may be performed after S202, after S203, or after S204.

Specifically, the network device may indicate P for the UE, or may not indicate P, and the network device may indicate starting resource information for the UE, or may not indicate starting resource information for the UE. Thus the UE may have the following 4 ways to determine P resource information:

(1) In the case where the network device indicates the first value P for the UE and indicates that the starting resource information is the first starting resource information, the UE may determine P resource information (h=p) according to the first value P and the first starting resource information.

For example, if the network device indicates that p=4 and the initial CSI-RS port number is CSI-RS port 2 for the UE, the UE may determine that 4 resource information is CSI-RS port 2, CSI-RS port 3, CSI-RS port 4, and CSI-RS port 5. The network device indicates that p=4 for the UE, and the initial CSI-RS resource is CSI-RS resource 2, then 4 resource information is CSI-RS resource 2, CSI-RS resource 3, CSI-RS resource 4, and CSI-RS resource 5.

(2) In the case where the network device indicates the first value P for the UE and does not indicate the start resource information for the UE, the UE may determine one resource information as the start resource information (e.g., the UE may determine one resource information as the start resource information according to the signal strength of the reference signal), and determine P consecutive resource information in which the one resource information is the start resource information as P resource information (h=p) of the UE measurement reference signal.

For example, the network device indicates p=4 for the UE, and the UE determines that the starting port number is CSI-RS port 4, and determines CSI-RS port 4, CSI-RS port 5, CSI-RS port 6, and CSI-RS port 7 as port numbers corresponding to the reference signals to be measured. The network device indicates that p=3 for the UE, and the UE may determine that the initial CSI-RS resource is the CSI-RS resource 5 according to the distance between the UE and the antenna unit, and determine that the CSI-RS resource 5, the CSI-RS resource 6, and the CSI-RS resource 7 are CSI-RS resources corresponding to the reference signal to be measured.

(3) In the case where the network device does not indicate the first value P for the UE and does not indicate the starting resource information for the UE, the UE may determine H resource information (e.g., may determine the corresponding H resource information according to the signal strength of the received reference signal).

For example, the network device does not indicate P and initial resource information for the UE, the UE may determine the CSI-RS port 4, the CSI-RS port 5, the CSI-RS port 6, the CSI-RS port 7, and the CSI-RS port 8 as CSI-RS port numbers (h=5) corresponding to the reference signals to be measured, and the UE may determine the CSI-RS resource 5, the CSI-RS resource 6, and the CSI-RS resource 7 as CSI-RS resource (h=3) corresponding to the reference signals to be measured.

(4) In the case where the network device does not indicate the first value P for the UE and indicates that the starting resource information is the first starting resource information for the UE, the UE may determine H resource information (e.g., the UE may determine H resource information corresponding to the signal strength of the reference signal) in combination with the first starting resource information.

For example, if the network device indicates that CSI-RS port 1 is the starting CSI-RS port number, the UE may determine CSI-RS port 1, CSI-RS port 2, and CSI-RS port 3 as CSI-RS port numbers corresponding to the reference signals to be measured (UE determines p=3). The network device indicates that the CSI-RS resource 3 is an initial CSI-RS resource, and the UE may determine that the CSI-RS resource 3, the CSI-RS resource 4, the CSI-RS resource 5, and the CSI-RS resource 6 are CSI-RS resources corresponding to the reference signal to be measured (UE determines p=4).

For example, assuming that the reference signal measured by the UE is CSI-RS, the UE may perform joint measurement and calculation on the H resource information, and the obtained measurement result may include: RI, PMI, CQI.

It should be noted that, compared with measuring the reference signals sent on M antenna units, the number of rows and columns of the matrix of the PMI is related to H, where H is less than or equal to N, so that the complexity of calculating the PMI by the UE is lower compared with the traditional measurement configuration method.

Optionally, in an embodiment of the present invention, the measurement result may include Q channel state information reference signal indexes (CSI-RS index, CRI), Q is a positive integer, and 1<Q is less than or equal to H.

For example, with reference signals measured by the UE as CSI-RS, after the UE measures the corresponding reference signals on the H resource information, the measurement result CSI reported by the UE may include: q CRI and CQI. Wherein the CQI is calculated based on CRI. The number of CRIs may indicate data flows that may be supported, e.g., if the number of CRIs is 1, the UE may support 1 flow of data, and if the number of CRIs is 2, the UE may support 2 flows of data.

Optionally, if the network device does not indicate the first value for the UE, the UE needs to measure all the N resource information, then selects H resource information corresponding to the reference signal with the reference signal strength greater than the signal strength threshold according to the signal strength of the measured reference signal, and then calculates to obtain the measurement result according to the reference signal corresponding to the H resource information.

For example, if the UE reports Q CRIs, the UE may report the second value H to the network device, or may not report the second value H to the network device.

It should be noted that, when the network device does not indicate the first value P to the UE, the number of CRI reported by the UE may be equal to the second value H; in the case where the network device indicates the first value P for the UE, the number of CRI reported by the UE may be less than or equal to the second value H. The number of CRI reported by the UE may also represent the number of resource information with better signal quality in the reference signals corresponding to the P resource information measured by the UE.

S206, the UE sends measurement feedback information to the network equipment.

The measurement feedback information includes a measurement result, or at least one of a second value H and initial resource information, and the measurement result, where the initial resource information is initial resource information in the H resource information.

Of course, the UE may report the second value H, where H may be the first value indicated by the network device, or may be the number of resource information corresponding to the UE measurement reference signal determined from the N pieces of resource information determined by the UE.

It may be appreciated that, if the network device does not indicate the first value to the UE, the second value reported by the UE may enable the network device to determine what reference signals corresponding to the resource information the UE measures.

Specifically, if the network device does not indicate the first value to the UE, the feedback information sent by the UE may not include the second value H if the resource information is CRI-RS.

Based on the scheme, after receiving measurement configuration information sent by the network device, the UE may send at least one of the first value P indicated by the network device and the first initial resource information indicated by the network device according to the measurement configuration information or according to the measurement configuration information, and measure reference signals corresponding to H resource information in the N resource information.

Optionally, the measurement configuration method provided in the embodiment of the present invention may further include S207:

s207, the network equipment receives measurement feedback information sent by the UE.

The measurement feedback information includes measurement results corresponding to H resource information measured by the UE, or includes at least one of the second value H and the second starting resource information and measurement results corresponding to the H resource information.

In the embodiment of the present invention, the second value H is the first value P, or is the number of resource information corresponding to the UE measurement reference signal determined from the N pieces of resource information by the UE; the second initial resource information is initial resource information in the H resource information.

Optionally, in the embodiment of the present invention, the second starting resource information is first starting resource information indicated by the network device, or is starting resource information determined by the UE from the N pieces of resource information.

It may be appreciated that if the network device does not indicate the initial resource information for the UE, the second initial resource information reported by the UE may enable the network device to determine which reference signals corresponding to the resource information are measured by the UE.

For example, if the network device determines that the channel state satisfies the transmission condition according to the measurement result, the network device may send data, such as physical downlink shared channel data (Physical Downlink Shared Channel, PDSCH), to the UE according to the channel state information.

Based on the scheme, after the network equipment receives the measurement feedback information sent by the UE, the network equipment can determine the measurement result of the reference signal sent on the antenna unit corresponding to the P resource information measured by the UE, or the measurement result of the reference signal sent on the antenna unit corresponding to the P resource information and the second initial resource information, and can determine whether the transmission condition is satisfied or not according to the measurement result, if the network equipment does not indicate the initial resource information for the UE, the network equipment can determine which reference signals corresponding to the resource information the UE actually measures according to the second initial resource information, so the configuration mode and the feedback mode of the measurement result in the measurement configuration method provided by the embodiment of the invention are more flexible.
