Detailed Description

Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.

Terms related to embodiments of the present application will be described below.

1. Network side equipment energy conservation

At present, in an NR system, a plurality of shutdown techniques can be adopted by network side equipment, so that the electric quantity consumption of the network side is reduced, and the purpose of energy conservation is achieved. Among other things, the plurality of shutdown techniques may include: symbol off technology, carrier off technology, channel off technology, and deep sleep technology.

Symbol off technology principle:

the network side device can turn off a Power switch of a Power Amplifier (PA) at the symbol period time when no data is transmitted, and turn on the PA Power switch at the symbol period time when data is transmitted, so as to reduce system Power consumption under the condition of ensuring that service is not affected.

Note that, since the symbol off technique uses the discontinuous transmission (Discontinuous Transmission, DTX) technique, the symbol off technique may also be referred to as a DTX power saving technique.

Carrier wave cut-off technology

The network side equipment can migrate the UE served by the network side equipment to the basic coverage layer cell and turn off the capacity layer cell under the condition of lower load of the capacity layer cell so as to achieve the effect of energy conservation. Under the condition that the load of the base coverage layer cell is increased, the network side equipment can wake up the capacity layer cell and migrate the served part of UE to the wake-up capacity layer cell.

Channel shutdown techniques

When the load of the cell is low, the network side equipment can close the transmitting channel (or the receiving channel) by adopting different granularity according to the load level of the cell so as to realize energy saving. After the channel is turned off, the network side equipment can compensate the work rate of the broadcast and data channels so as to ensure the coverage and performance of the network.

2. Airspace energy-saving technology of network side equipment

Currently, in NR systems, network-side devices are provided with massive multiple-input multiple-output (Massive Multiple Input Multiple Output, mimo) arrays. However, the power consumption of the mimo array is high, so the network side device may deactivate a portion of the ports of the mimo array in a time slot without data transmission, so as to reduce the power consumption of the network side device.

The reference signal measurement method, the reference signal measurement device, the reference signal measurement terminal, the reference signal measurement network side equipment and the reference signal measurement medium provided by the embodiment of the application are described in detail below by means of some embodiments and application scenes of the reference signal measurement method, the reference signal measurement device, the reference signal measurement terminal and the network side equipment with reference to the attached drawings.

Fig. 2 shows a flowchart of a reference signal measurement method according to an embodiment of the present application. As shown in fig. 2, the reference signal measurement method provided in the embodiment of the present application may include the following steps 101 and 102.

Step 101, the UE receives target indication information.

In this embodiment of the present application, the target indication information is used to indicate a change of a correlation attribute of a Reference Signal (RS) to be measured.

Optionally, in an embodiment of the present application, the correlation attribute of the reference signal may include at least one of the following: the resource location of the reference signal, the state of the port (port) occupied by the reference signal, the number of ports occupied by the reference signal, the code division multiplexing (Code Division Multiplexed, CDM) type of the reference signal, the Density (Density) of the reference signal, the number of CDM packets, the mode information of the network side device closing the port, the mode switching information of the network side device, the number of the network side device closing the port, the number of the network side device opening the port, and the like.

The resource location may specifically be a time-frequency domain location.

Optionally, in the embodiment of the present application, the UE may receive the target indication information from the network side device. The target indication information may be sent by the network side device to the UE before (or after) the mode switching of the network side device takes effect.

Wherein the modes may include at least one of: sleep mode (sleep mode), power mode (power mode), operational mode. The sleep mode may include at least one of: light sleep mode, micro sleep mode, medium sleep mode, deep sleep mode, light sleep mode, etc. The operating mode may include at least one of: energy saving mode, non-energy saving mode, etc.

It can be appreciated that if the mode switching of the network side device is effective, the state of the port of the network side device may change (e.g., the state of the port changes from an on state to an off state, etc.), that is, the resource location of the reference signal to be measured by the UE may change. Thus, the network side device may send the target indication information to the UE.

It should be noted that, the words "shallow" in the shallow sleep mode, the words "micro" in the micro sleep mode, the words "deep" in the deep sleep mode, etc. may also be expressed in other ways, for example, the words "shallow" (or the words "micro" or the words "deep") may be expressed by any one of the words "medium", the words "light", the words "deep", the words "micro" and the words "macro", which is not limited in the embodiment of the present application.

Alternatively, in the embodiment of the present application, as shown in fig. 3 in conjunction with fig. 2, the above step 101 may be specifically implemented by the following step 101 a.

Step 101a, the UE receives the target signaling from the network side device.

In this embodiment of the present application, the target indication information is carried in a target signaling; the target signaling includes any of the following: layer 1 signaling, media access Control layer (MediumAccessControl, MAC) Control Element (CE), downlink Control information (Downlink Control Information, DCI); the DCI includes at least one of: UE-specific DCI, group common DCI (group common DCI).

Step 102, the UE performs a first operation on the reference signal according to the target indication information.

In an embodiment of the present application, the first operation includes any one of the following:

determining a resource location of the reference signal and measuring the reference signal at the resource location;

the measurement of the reference signal is cancelled.

Optionally, in the embodiment of the present application, the UE may determine a correlation attribute of the changed reference signal according to the target indication information, so as to determine a first operation according to the correlation attribute, and execute the first operation.

In this embodiment of the present invention, if the state of the port of the network side device changes, the network side device may send target indication information to the UE to indicate a change of the correlation attribute of the reference signal to be measured, so that the UE may perform the first operation, so that the UE may cancel (or reduce) the actions such as measurement reporting of the reference signal corresponding to the port closed by the network side device, and may increase the actions such as measurement reporting of the reference signal corresponding to the port opened by the network side device.

According to the reference signal measurement method provided by the embodiment of the application, the UE can receive the target indication information for indicating the change of the correlation attribute of the reference signal to be measured, and execute the first operation on the reference signal according to the target indication information; wherein the first operation is to determine a resource location of the reference signal and to measure the reference signal at the resource location or cancel the measurement of the reference signal. The UE can receive the target indication information to determine the change of the related attribute of the reference signal to be measured, and re-determine the resource position of the reference signal according to the target indication information so as to measure the reference signal at the resource position instead of the resource position configured for the UE in advance by the network side equipment, so that the situation that the resource position of the reference signal is changed can be comprehensively considered, and the accuracy of the measurement result of the reference signal measured by the UE is improved; or, the UE may cancel measurement of the reference signal according to the target indication information, so that unnecessary measurement by the UE may be avoided to reduce the error rate of the measurement result, and thus the accuracy of the measurement result of the reference signal measured by the UE may be ensured. That is, inaccuracy of the measurement result of the reference signal by the UE due to the change of the resource location of the reference signal can be avoided; or, the UE may cancel measurement of the reference signal according to the target indication information, so that unnecessary measurement by the UE may be avoided; in this way, the communication performance of the device can be ensured.

And when the network side device opens or closes the port due to mode switching, the UE does not need to release the original configuration, and does not need to re-activate the new report Setting or resource set Setting, but only needs to receive the target indication information of the network side device, learn that part of the ports of the network side device are opened or closed, and according to the indication, correspondingly adjust the actions such as measurement, monitoring, reporting, and the like, for example, the measurement is not needed on part of the ports of the network side device, and the closed ports are not considered when calculating the channel state information (Channel State Information, CSI), and the like.

The contents of the target instruction information will be specifically exemplified below.

Optionally, in an embodiment of the present application, the target indication information includes at least one of the following:

first indication information;

and second indication information.

In this embodiment of the present application, the first indication information is used to indicate relevant change information of the reference signal; the second indication information is used for indicating the switching of the mode of the network side equipment.

Optionally, in the embodiment of the present application, the second indication information is used to indicate a mode to which the network side device is switched.

For example, the second indication information may be used to instruct the network-side device to switch from the power saving mode to the non-power saving mode; or, the method can be used for indicating the network side equipment to switch from the non-energy-saving mode to the energy-saving mode; or, the method can be used for indicating the network side equipment to switch from the light sleep mode to the micro sleep mode; or, the method can be used for indicating the network side equipment to switch from the micro sleep mode to the light sleep mode; or, the method can be used for indicating the network side equipment to switch from the micro sleep mode to the deep sleep mode; or may be used to instruct the network side device to switch from deep sleep mode to microsleep mode.

Optionally, in an embodiment of the present application, the first indication information includes at least one of:

the number change information of the ports occupied by the reference signals;

CDM type variation information of the reference signal;

density change information of the reference signal;

numbering of target CDM packets;

and the network side equipment closes the information of the port according to a preset mode.

The number change information of the ports occupied by the reference signals specifically indicates: the number of ports occupied by the changed reference signal.

Illustratively, assuming that the number of ports occupied by the reference signal is changed by 4, the number of ports occupied by the changed reference signal can be considered to be 4.

Wherein, CDM type change information of the reference signal specifically indicates: CDM type of the changed reference signal.

Wherein, the density change information of the reference signal specifically indicates: density of the reference signal after the change.

The target CDM packet is a CDM packet corresponding to a target port, where the target port includes any one of the following: the port opened by the network side equipment and the port closed by the network side equipment.

Optionally, in an embodiment of the present application, the preset manner includes at least one of the following:

closing the ports according to a preset proportion;

closing the ports according to parity of the port numbers;

closing the port as indicated by the list configured by radio resource control (Radio Resource Control, RRC) signaling;

closing the ports according to the code of CDM group;

and closing the ports in the ports corresponding to each CDM group according to the preset quantity.

Wherein, the preset proportion can comprise any one of the following: 1/2, 1/4, 1/8, etc.

The network side device may close the odd numbered ports of the ports, or may close the even numbered ports of the ports.

Before the UE receives the target indication information, the network side device may send an RRC signaling to the UE, where a port list to be closed after the network side enters the energy saving state is configured in the RRC signaling, and a correspondence or binding relationship between different indexes (or different values) and different ports is configured in the list, so that the UE may determine, according to the content of the list, a port closed by the network side device. For example, the list contains a plurality of index values, index value 1 corresponds to portx, index value 2 corresponds to porty, these correspondence relationships can be configured by the network, and then the UE can know which ports are closed by receiving the RRC list.

After the UE receives the target indication information, the network side device may send the number of the CDM packet to the UE, so that the UE may determine, according to the number of the CDM packet, a port closed by the network side device (i.e., a port corresponding to the number of the CDM packet).

The preset number may be predetermined by the network device or agreed by a protocol. And under the condition that the preset number is preset by the network side equipment, the network side equipment can close the preset number of ports in the port set corresponding to each CDM group according to a first preset mode.

The first preset mode comprises at least one of the following: closing the ports according to a preset proportion; closing the ports according to parity of the port numbers; closing the port according to the indication of the list configured by the RRC signaling; the ports are closed according to the CDM packet number.

For example, assuming that the preset number is preset by the network side device and the first preset manner is to close the ports according to the preset proportion, the network side device may determine the preset number according to the preset proportion according to the number of ports corresponding to one CDM packet, close the preset number of ports in the port set corresponding to the one CDM packet, and so on, so as to close the ports in the port set corresponding to each CDM packet according to the preset number.

Also for example, assuming that the preset number is predetermined by the network side device and the first preset manner is to close ports according to parity of the number of ports, the network side device may close ports with odd numbers (or even numbers) of ports corresponding to each CDM packet.

Optionally, in an embodiment of the present application, an indication manner of the first indication information includes at least one of the following: indicated by a numerical value, indicated by a bit map (bitmap).

In the case that the indication mode of the first indication information is that the indication is performed by a numerical value, the first indication information may specifically be a number, or the number of closed ports, or the number of open ports.

For example, assuming that the first indication information is a number, for example, the CDM packet number j= {0,1,2}, the network side device may be considered to close the port corresponding to the CDM packet number j= {0,1,2 }.

Also by way of example, assuming that the first indication information is a number, for example, the port number p= {1001, 1002}, the network side device may be considered to close the port having the port number p= {1001, 1002 }.

Also for example, assuming that the network side device includes 6 sets of CDM packets, bitmap= {010101}, the network side device is to close the port corresponding to CDM packet numbered {1,3,5 }.

Also by way of example, assuming that each CDM packet of the network side device has 4 ports, the 4 ports are numbered {0,1,2,3}, bitmap= {0011}, the network side device is to close the two ports with the smallest port number in each CDM packet.

Optionally, in an embodiment of the present application, the indication granularity of the first indication information includes any one of the following: each set of resources of the reference signal, each resource of the set of resources of the reference signal.

By way of example, the indication granularity of the first indication information is taken as a reference signal resource set. The network side device may send indication information to all UEs served by the network side device respectively to indicate to all UEs the change of the relevant attribute of the reference signal to be measured, fig. 4 indicates to the network side device for each (one) UE, where the network side device indicates the change of the relevant attribute of the reference signal to be measured in each Resource Set with granularity of a Resource Set, for example, the number change information and the density change information of the ports occupied by the reference signal to be measured in the Resource Set with a Resource Set Id (i.e. Resource Set id_a), and the number change information and the density change information of the ports occupied by the reference signal to be measured in the Resource Set with b Resource Set Id (i.e. Resource Set id_b).

By way of example, the indication granularity of the first indication information is described as each resource in the reference signal resource set. The network side device may send indication information to all UEs served by the network side device respectively to indicate to all UEs about the change of the correlation attribute of the reference signal to be measured, fig. 5 indicates to the network side device for each (one) UE that the network side device indicates the change of the correlation attribute of the reference signal to be measured with the granularity of each Resource in each Resource Set, for example, the number change information and the density change information of the ports occupied by the reference signal to be measured of the Resource Set Id a (i.e., resource Set id_a) with the Resource Id of 0 (i.e., resource id_0), the number change information and the density change information of the ports occupied by the reference signal to be measured of the Resource Id 1 (i.e., resource id_1), and so on.

The first operation will be described below as an example of determining a resource location of a reference signal and measuring the reference signal at the resource location, for example, how the UE performs the first operation.

Further optionally, in the embodiment of the present application, the UE may determine, from the resource mapping information list, resource mapping information that matches the first indication information, so as to determine target resource mapping information.

In case that the UE determines that the resource mapping information matched with the first indication information is one resource mapping information, the UE may directly determine the one resource mapping information as the target resource mapping information.

For example, assuming that the first indication information includes density variation information of the reference signal, for example, 3, the UE may directly determine one resource mapping information (i.e., resource mapping information of ROW 1) matched with the density variation information (i.e., 3) from the resource mapping information list and determine the resource mapping information of ROW1 as the target resource mapping information.

In the case that the UE determines that the resource mapping information matched with the first indication information is a plurality of resource mapping information, the UE may determine target resource mapping information from the plurality of resource mapping information.

The step of determining target resource mapping information from the plurality of resource mapping information by the UE will be illustrated.

Alternatively, in the embodiment of the present application, the above step 102a may be specifically implemented by the following steps 102a1 and 102a 2.

Step 102a1, the UE determines M pieces of resource mapping information matched with the first indication information from the resource mapping information list.

In the embodiment of the present application, M is a positive integer greater than 1.

For example, assuming that the first indication information includes information of a change in the number of ports occupied by the reference signal, for example, 4, the UE may determine M pieces of resource mapping information matching the information of the change in the number of ports occupied by the reference signal (i.e., 4), i.e., resource mapping information of ROW4 and resource mapping information of ROW5, from the resource mapping information list.

Step 102a2, the UE determines target resource mapping information satisfying a first preset condition from the M resource mapping information.

In this embodiment of the present application, the first preset condition includes any one of the following:

The resource mapping information corresponding to the largest number in the M resource mapping information;

the resource mapping information corresponding to the minimum number in the M resource mapping information;

the resource mapping information indicated by the resource mapping indication carried in the first indication information.

For example, assuming that the first preset condition is the resource mapping information corresponding to the largest number in the M resource mapping information, the UE may determine target resource mapping information satisfying the first preset condition, that is, the resource mapping information of ROW5, from the resource mapping information of ROW4 and the resource mapping information of ROW 5.

Also for example, assuming that the first preset condition is the resource mapping information corresponding to the minimum number in the M resource mapping information, the UE may determine target resource mapping information satisfying the first preset condition, that is, the resource mapping information of ROW4, from the resource mapping information of ROW4 and the resource mapping information of ROW 5.

Further optionally, in the embodiment of the present application, in a case that the first indication information carries a resource mapping indication, the first preset condition may be resource mapping information indicated by the resource mapping indication carried in the first indication information.

Step 102b, the UE determines the resource location according to the target resource mapping information.

Further optionally, in the embodiment of the present application, the UE may calculate, according to the resource location included in the target resource mapping information, a resource location of the reference signal to be measured.

Therefore, the UE can accurately determine the target resource mapping information according to the first indication information by using the resource mapping information list, so as to accurately determine the resource position of the reference signal to be measured according to the target resource information, so as to measure the reference signal at the resource position, and therefore, the accuracy of measuring the reference signal can be improved.

Example one:

the network side device switches from mode1 (mode 1) to mode2 (mode 2), and the network side device associates 1 resource set (and the number of Ports of the resources in the resource set is the same) in the CSI-RS report config configured by the UE, and the number of Ports of the resources in the resource set is ports=8.

Take one resource ports=8, density=1, CDM-type=fd-CDM 2 as an example.

After the mode switching of the network side device takes effect, the network side device may send, to the UE, target indication information (the target indication information is first indication information) through the group public DCI, where the first indication information includes information about a change in the number of ports occupied by the reference signal (for example, the number of ports changes to 4 ports), and in combination with table 1, the UE may determine, from the resource mapping information list, M resource mapping information (that is, resource mapping information of ROW4 and resource mapping information of ROW 5) that matches with the information about a change in the number of ports occupied by the reference signal (that is, 4 ports), so that the UE may determine, from the resource mapping information of ROW4 and the resource mapping information of ROW5, target resource mapping information (for example, resource mapping information of ROW 4) that meets a first preset condition, that is, consider the resource mapping information of ROW4 to be the time-frequency domain position of CSI-RS resource associated with reporting configuration (reporting configuration), and thus, it is not necessary to deactivate a new reporting configuration (reporting configuration).

Scheme II,

Optionally, in the embodiment of the present application, the target indication information includes second indication information, where the second indication information is used to indicate that a mode of the network side device is switched to a target mode; the first operation includes determining a resource location of a reference signal and measuring the reference signal at the resource location. Specifically, as shown in fig. 7 in conjunction with fig. 2, the above step 102 may be specifically implemented by the following steps 102c to 102 e.

Step 102c, the UE determines target port configuration information corresponding to the target mode from the N association relations.

In this embodiment of the present application, each of the N association relationships is an association relationship between a mode of a network side device and one port configuration information, where the N association relationships are configured by a network side device through a higher layer signaling in advance, or are agreed by a protocol; n is a positive integer. For example, a deep sleep mode of the network side device is associated with port configuration information 1, a light sleep mode is associated with port configuration information 2, and so on.

Step 102d, the UE determines the target port according to the target port configuration information.

In an embodiment of the present application, the target port includes any one of the following: the port opened by the network side equipment and the port closed by the network side equipment.

Further optionally, in the embodiment of the present application, the UE may determine the number of the target port according to the configuration information of the target port, so as to determine the target port.

Step 102e, the UE determines the resource location according to the target port.

Further optionally, in the embodiment of the present application, the UE may determine, according to the resource location associated with the target port, the resource location of the reference signal to be measured.

Therefore, the UE can accurately determine the target port configuration information corresponding to the target mode by adopting N incidence relations, and accurately determine the resource position of the reference signal to be measured based on the target port configuration information so as to measure the reference signal at the resource position, so that the accuracy of measuring the reference signal can be improved.

Scheme III,

Optionally, in an embodiment of the present application, the target indication information includes first indication information; the first operation includes determining a resource location of a reference signal and measuring the reference signal at the resource location. Specifically, as shown in fig. 8 in conjunction with fig. 2, the above step 102 may be specifically implemented by the following steps 102f to 102 h.

Step 102f, the UE determines the number of the target CDM packet according to the first indication information.

Further alternatively, in the embodiment of the present application, in a case where the first indication information includes the number of the target CDM packet, the UE may directly determine the number of the target CDM packet according to the first indication information.

Step 102g, the UE determines a target port corresponding to the target CDM packet.

Step 102h, the UE determines the resource position according to the target port.

As can be seen from this, since the UE can directly determine the number of the target CDM packet, and accurately determine the target port according to the number of the target CDM packet, and accurately determine the resource location of the reference signal to be measured according to the target port, so as to measure the reference signal at the resource location, the accuracy of measuring the reference signal can be improved.

Example two:

fig. 9 shows a schematic diagram of different CDM packets on different ports of a network side device. As shown in fig. 9, the numbers of the four CDM packets are {0,1,2,3}, respectively, i.e., the number of the first CDM packet is j=0, corresponding to two ports {3000, 3001}; the second CDM packet is numbered j=1, corresponding to two ports {3002, 3003}; the third CDM packet is numbered j=2, corresponding to two ports {3004, 3005}; the fourth CDM packet is numbered j=3, corresponding to two ports {3006, 3007}.

When the mode of the network side device is switched to the target mode (for example, the energy saving mode), as shown in fig. 10, the network side device may close some ports of the ports {3000, 3001, 3003, 3004, 3005, 3006, 3007} to achieve the purpose of energy saving; as shown in fig. 11, when the network side device closes two ports corresponding to the first CDM packet (i.e., {3000, 3001 }), the network side device may send target indication information (the target indication information is the first indication information) to the UE, where the first indication information includes the number of the first CDM packet, so that the UE may not need to measure the two ports, i.e., the ports {3000, 3001}, in a subsequent measurement process.

The effective time of the target instruction information will be exemplified below.

Optionally, in the embodiment of the present application, when the target indication information includes first indication information and second indication information, and the first indication information includes the second indication information, the effective time of the target indication information is the first time.

The first time is the effective time of the mode switching of the network side equipment.

It can be understood that the effective time of the target indication information is the same as the effective time of the mode switching of the network side device.

Optionally, in the embodiment of the present application, when the target indication information includes first indication information and second indication information, and the first indication information does not include the second indication information, the effective time of the target indication information is the second time.

Wherein the second time comprises any one of: the method comprises the steps of starting time of an X-th time unit after a time unit where first indication information is located, ending time of an X-th time unit after the time unit where the first indication information is located, a preset available effective position after the time unit where the first indication information is located, starting time of a Y-th time unit after a time unit where second indication information is located, and ending time of a Y-th time unit after the time unit where the second indication information is located; the preset available effective position is preconfigured for network side equipment or agreed by a protocol; x, Y are all positive integers.

The time cell may comprise any of the following: slot, subframe, frame.

Fig. 12 shows a flowchart of a reference signal measurement method according to an embodiment of the present application. As shown in fig. 12, the reference signal measurement method provided in the embodiment of the present application may include the following step 201.

Step 201, the network side device sends target indication information to the UE.

Optionally, in the embodiment of the present application, before (or after) the mode switching of the network side device takes effect, the network side device may send the target indication information to the UE.

In this embodiment of the present application, the target indication information is used to indicate a change of a correlation attribute of a reference signal to be measured; the target indication information is used for the UE to perform a first operation on the reference signal.

Wherein the first operation comprises any one of:

the measurement of the reference signal is cancelled.

Alternatively, in the embodiment of the present application, the above step 201 may be specifically implemented by the following step 201 a.

Step 201a, the network side device sends a target signaling to the UE.

In this embodiment of the present application, the target indication information is carried in a target signaling; the target signaling includes any of the following: layer 1 signaling, MAC CE, DCI; the DCI includes at least one of: UE-specific DCI, group common DCI.

Alternatively, in the embodiment of the present application, the above step 201 may be specifically implemented by the following step 201b or step 201 c.

Step 201b, the network side device sends indication information to all UEs served by the network side device.

In this embodiment of the present application, all UEs described above include UEs in the foregoing embodiment.

In this embodiment of the present application, the network side device may indicate, according to each serving cell, each UE (Per Serving cell PerUE) to change the correlation attribute of the reference signal to be measured.

In this embodiment of the present application, the content of the indication information received by Q UEs in all UEs is the same, and Q is an integer greater than or equal to 0.

It is understood that the content of the indication information received by all UEs may be identical, or partially identical, or completely different.

For example, fig. 13 shows a schematic diagram of a network side device sending indication information to all UEs served by the network side device. As shown in fig. 13, the network side device may send indication information to all UEs (e.g., UE 0 to UE K), where UE 0 to UE K include the UEs in the above embodiments. The indication information received by the UE 0 may include information of a change in the Number of Ports occupied by the reference signal (for example, number of ports=16) and information of a change in the CDM Type of the reference signal (for example, CDM-type=cdm4), the indication information received by the UE 1 may include information of a change in the Number of Ports occupied by the reference signal (for example, number of ports=16), … …, and the indication information received by the UE K may include information of a change in the Number of Ports occupied by the reference signal (for example, number of ports=16) and information of a change in the Density of the reference signal (for example, density=0.5). Wherein, the content of the indication information received by each UE in the UE 0 to the UE K is different, namely Q is 0. So that the UE 0 to UE K can decode the corresponding indication information respectively and apply to all resource sets.

As shown in fig. 13, for UE 0, assuming that the number of ports occupied by the initial reference signal of UE 0 is 32 and the CDM type of the reference signal is FD-CDM2, the number of ports of all resources in the resource set of all reference signals of UE 0 becomes 16 and the CDM type of all resources in the resource set of all reference signals becomes CDM4 according to the indication information received by UE 0.

Step 201c, the network side device sends indication information to all UE packets served by the network side device.

In this embodiment of the present application, the all UE packets include a target UE packet to which the UE belongs.

In the embodiment of the application, the network side device may indicate the change of the relevant attribute of the reference signal to be measured according to each UE group (Per Serving cell Per UE group) of each serving cell.

In this embodiment of the present application, the content of the indication information received by each UE in R UE groups in all UE groups is the same, the content of the indication information received by the UE in any UE group is the same, and R is an integer greater than or equal to 0.

It is understood that the content of the indication information sent by the network side device to all UE packets may be completely the same, partially the same, or completely different. The content of the indication information received by the UE in any UE packet is the same.

By way of example, fig. 14 shows a schematic diagram of a network-side device sending indication information to all UE packets it serves. As shown in fig. 14, the network side device may send indication information to all UE groups (for example, UE group 0 to UE group G), where the UE group 0 to UE group G include the target UE group to which the UE belongs. Wherein the indication information received by each UE in the UE group 0 may include information of a change in the Number of Ports occupied by the reference signal (e.g., number of ports=16) and information of a change in the CDM Type of the reference signal (e.g., CDM-type=fd-CDM 2), the indication information received by each UE in the UE group 1 may include information of a change in the Number of Ports occupied by the reference signal (e.g., number of ports=16), … …, and the indication information received by each UE in the UE group G may include information of a change in the Number of Ports occupied by the reference signal (e.g., number of ports=16) and information of a change in the Density of the reference signal (e.g., density=0.5). Wherein, the content of the indication information received by each UE in each UE group in the UE group 0 to UE group G is the same, i.e. R is 0. That is, when a UE decodes indication information with its belonging group ID, it is known that the indication information is for all UEs of its belonging group.

According to the reference signal measurement method provided by the embodiment of the application, the network side equipment can send the target indication information for indicating the change of the related attribute of the reference signal to be measured to the UE, so that the UE can execute the first operation on the reference signal; wherein the first operation is to determine a resource location of the reference signal and to measure the reference signal at the resource location or cancel the measurement of the reference signal. The network side equipment can send the target indication information to the UE so as to indicate the change of the relevant attribute of the reference signal to be measured to the UE, so that the UE can redetermine the resource position of the reference signal according to the target indication information, and the reference signal is measured at the resource position instead of the resource position corresponding to the resource concentrated resource configured by the network side equipment in advance for the UE. Therefore, the method and the device can comprehensively consider the condition that the resource position of the reference signal changes, so that the accuracy of the measurement result of the reference signal measured by the UE is improved; or, the UE may cancel measurement of the reference signal according to the target indication information, so that unnecessary measurement by the UE may be avoided to reduce the error rate of the measurement result, and thus the accuracy of the measurement result of the reference signal measured by the UE may be ensured. That is, inaccuracy of the measurement result of the reference signal by the UE due to the change of the resource location of the reference signal can be avoided; or, the UE can cancel the measurement of the reference signal according to the target indication information, so that the inaccuracy of the measurement result of the UE for measuring the reference signal can be avoided; in this way, the communication performance of the device can be ensured.
