Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a flowchart of a first embodiment of a power measurement method of the present invention, and as shown in fig. 1, the method of this embodiment may include:

step 101, receiving a reference power reference signal transmitted by a transmitter on a corresponding transmission resource according to configuration information of the reference power reference signal, wherein the configuration information includes information of the transmission resource corresponding to the reference power reference signal, and the transmission resource includes any combination of all resource units that can be decoded by a UE;

and 102, performing power measurement according to the reference power reference signal.

Specifically, the existing power measurement uses a fixed RS, for example, uses a transmission resource corresponding to a CRS or a CSI-RS. For example, the number of ports of the CSI-RS resource may be 1, 2, 4, or 8, and each CSI-RS port may correspond to a plurality of Resource Elements (REs). When performing power measurement, the transmitter may send CSI-RS to the receiver on the CSR-RS port, and the receiver may perform power measurement using the CSI-RS received on the CSR-RS port. However, with the increasing types of power measurement and the complex and variable interference environment, the power measurement method using a fixed RS in the prior art is not flexible enough, or the RS resource is not sufficient, or the RS resource is redundant, and the power measurement may be inaccurate, so that the current RS design may not be completely consistent with the purpose of power measurement, and the power measurement that cannot be performed using the current RS design may occur. Moreover, with the power measurement method in the prior art, the transmitter cannot flexibly control the power measurement process of the receiver.

In order to solve the above problems that may occur when the prior art performs power measurement, the power measurement does not need to be bound to the existing RS resources, and for different power measurement types, the used REs may not belong to one RS, or all REs of one RS may be used for different types of power measurement.

For this purpose, the present embodiment defines an RS, i.e., a Reference Power Reference Signal or a Received Power Reference Signal (hereinafter referred to as RP-RS), which may also include a plurality of RP-RS ports, like the CSI-RS, and each RP-RS port may correspond to a plurality of REs. Unlike CSI-RS, the transmission resource corresponding to the RP-RS may be any combination of all REs that can be decoded by the receiver, that is, the RP-RS in this embodiment does not correspond to some REs only fixedly as CSI-RS in the prior art, but does not divide or limit the REs available to the receiver, and the transmission resource corresponding to the RP-RS may perform any combination of all REs that can be decoded by the receiver.

It should be noted that the RP-RS described in this embodiment is a general term for any RE combination, and for example, may be any user-decodable RE combination, that is, a new signal, or a combination of RE resources carrying existing signals. For example, if the transmission resource corresponding to the RP-RS is the RE combination corresponding to the CSI-RS resource, the receiver only receives and processes the RP-RS on the corresponding transmission resource according to the configuration information, and it still receives the CSI-RS.

In particular implementations, the REs that the receiver is capable of decoding may include: RE corresponding to a CSI-RS port, RE corresponding to a CSI-RS resource, RE corresponding to a CRS port, RE corresponding to a CRS resource, Positioning Reference Signal (PRS) port, RE corresponding to a Multicast/Multicast Single Frequency Network (MBSFN RS) port, RE corresponding to a UE-Specific reference signal (UE-Specific RS) port, RE corresponding to a Physical Downlink Control Channel (PDCCH), RE corresponding to a Physical Downlink Shared Channel (PDSCH) and SRS resource or RE corresponding to a port. Furthermore, the REs that can be decoded by the receiver may also be an aggregation of multiple signals in all the above signals, such as REs corresponding to aggregated multiple CSI-RS ports or REs corresponding to aggregated multiple CSI-RS resources. The RP-RS may also correspond to an aggregate resource. Where all of the above signals, such as CSI-RS, may be zero-powered or non-zero-powered. It should be noted that, this embodiment does not limit that the RE that the receiver can decode only includes the RE already defined in the above prior art.

The transmitter may send the configuration information related to the RP-RS to the receiver, or use a defined manner to enable both the transmitter and the receiver to know the configuration information of the RP-RS, so that the receiver may receive the RP-RS sent by the transmitter on the corresponding transmission resource according to the configuration information of the RP-RS, and perform power measurement according to the RP-RS signal.

In this embodiment, the receiver may obtain the configuration information of the RP-RS, so as to obtain which transmission resources corresponding to the RP-RS the transmitter will transmit on, and therefore, the receiver may receive, on the corresponding transmission resources, the RP-RS transmitted by the transmitter according to the configuration information of the RP-RS, and perform power measurement. Since the transmission resource corresponding to the RP-RS in this embodiment may include any combination of all REs that the receiver can decode, the transmitter may flexibly send the RP-RS on any RE combination through the configuration information, so that RE combinations may be performed for different measurement types, thereby avoiding a situation where some measured RS resources are not sufficient and some measured RS resources are redundant, and further making power measurement accurate. Moreover, with the technical solution of this embodiment, the transmitter can flexibly control the process of power measurement performed by the receiver through the configuration information.

The configuration information in the above embodiment may include the following information:

(1) and the corresponding relation between the RP-RS port and the RE combination on the time frequency resource block.

(2) And attribute information of the RP-RS port.

For example, the attribute information may include: one of scrambling code information and sequence information, transmission power information, time domain position information, and at least one of frequency domain position information. The time domain location information may include: time domain period information and position offset information within a period. The frequency domain location information includes: sub-band position information or band position information of the frequency domain. The information of the scrambling code or the sequence information can enable the transmitter to control which scrambling code or sequence is adopted by the receiver to perform descrambling processing on the signal.

The information described in (1) and (2) above is a general definition of an RP-RS, which may define a plurality of RP-RS ports, and the definition of each RP-RS port may include the information described in (1) and (2) above.

(3) And RP-RS port and measurement type information required by power measurement.

The information in (3) above, which is used to indicate on which RP-RS port or ports the transmitter specifically needs to send the RP-RS to the receiver, and indicate the type of measurement performed by the receiver using the RP-RS.

For example, the measurement type information may include: the information may include type information indicating RSRP measurement, type information indicating received power of an interference signal in Channel Quality Indicator (CQI) measurement, type information indicating received power of an effective signal in CQI measurement, and the like.

In addition, RP-RS resources can be defined, one RP-RS resource corresponds to one RP-RS port, and corresponds to the corresponding relation of the combination of the RP-RS port and the RE on the time frequency resource block (1) and the attribute information of the RP-RS port (2). Then (3) the RP-RS port and measurement type information required for power measurement may become the RP-RS resource and measurement type information required for power measurement.

In particular implementation, the transmitter may notify the receiver of the configuration information of the RP-RS in the following manner:

in the first mode, the transmitter sends a notification message to the receiver, wherein the notification message contains the corresponding relation between the RP-RS port and the RE combination on the time-frequency resource block, the attribute information of the RP-RS port, and the reference power reference signal port and the measurement type information which are required to be adopted for power measurement.

Based on the transmitter notifying the receiver in this way, correspondingly, the receiver can receive the notification message sent by the transmitter, receive the RP-RS sent by the transmitter on the corresponding transmission resource according to the content notified by the notification message, and perform power measurement corresponding to the measurement type information according to the RP-RS.

The transmitter sends two notification messages, namely a first notification message and a second notification message, to the receiver, wherein the first notification message comprises the corresponding relation between the RP-RS port and the RE combination on the time-frequency resource block and the attribute information of the RP-RS port; and the second notification message contains the RP-RS port and the measurement type information which are required to be adopted by the power measurement.

Based on the transmitter informing the receiver in this way, the receiver can receive a first notification message sent by the transmitter accordingly to know the definition of the RP-RS, and further, the receiver can receive a second notification message sent by the transmitter to know on which RP-RS port or ports the transmitter is to send the RP-RS and what measurement is to be performed by using the RP-RS. Then, the receiver may receive the RP-RS transmitted by the transmitter on the corresponding transmission resource according to the content notified by the first notification message and the content notified by the second notification message, and perform power measurement corresponding to the measurement type information according to the RP-RS.

And the transmitter sends a notification message to the receiver, wherein the notification message comprises attribute information of an RP-RS port on a time-frequency resource block, and RP-RS port and measurement type information required by power measurement.

In this way, the corresponding relation between the RP-RS port and the RE combination on the time-frequency resource block is defined, and the transmitter only needs to notify the attribute information of the RP-RS port and measurement type information required to be adopted for power measurement in one notification message.

Based on the transmitter, the receiver is informed by adopting the method, correspondingly, the receiver can receive the RP-RS sent by the transmitter on the corresponding transmission resource according to the content informed by the informing message and the corresponding relation between the RP-RS port and the RE combination on the configured time frequency resource block, and carry out power measurement corresponding to the measurement type information according to the RP-RS.

And the transmitter sends two notification messages, namely a first notification message and a second notification message, to the receiver, wherein the first notification message contains the attribute information of the RP-RS port, and the second notification message contains the RP-RS port and the measurement type information required by power measurement.

The difference between this method and the third method is that in this method, two notification messages are used to notify the receiver of the attribute information of the RP-RS port, the RP-RS port required for power measurement, and the measurement type information, and in this method, the correspondence between the RP-RS port and the RE combination on the time-frequency resource block is still defined.

Based on the transmitter notifying the receiver in this way, correspondingly, the receiver can receive the RP-RS sent by the transmitter on the corresponding transmission resource according to the content notified by the first notification message, the content notified by the second notification message, and the corresponding relationship between the RP-RS port and the RE combination on the configured time frequency resource block, and perform power measurement corresponding to the measurement type information according to the RP-RS.

And in the fifth mode, the transmitter sends a notification message to the receiver, wherein the notification message contains the RP-RS port and the measurement type information required by the power measurement.

In the method, the corresponding relation of the combination of the RP-RS ports and the REs on the time-frequency resource blocks and the attribute information of the RP-RS ports are defined, and the transmitter only needs to adopt one notification message to notify the receiver which RP-RS port or ports to measure.

Based on the transmitter notifying the receiver in this way, correspondingly, the receiver can receive the RP-RS sent by the transmitter on the corresponding transmission resource according to the content notified by the notification message, the corresponding relationship between the RP-RS port and the RE combination on the configured time-frequency resource block, and the attribute information of the RP-RS port, and perform power measurement corresponding to the measurement type information according to the RP-RS.

When the above-mentioned various modes one to five are implemented, the corresponding relationship between the RP-RS port and the RE combination on the time frequency resource block may be indicated by using a bitmap (hereinafter referred to as bitmap), where a bit of the bitmap may be one RE or all REs of one resource or one port. For example, a bitmap with a length of 32 may be used to indicate which RE corresponding to the RP-RS is the RE corresponding to the CSI-RS with 2 ports, or a bitmap with a length of 12 may be used to indicate which RE corresponding to the RP-RS is the RE corresponding to the CSI-RS with 2 ports on 9/10 th symbols in the RB pair, or a bitmap with a length of 12 may be usedA bitmap of 6 indicates that the RE corresponding to the RP-RS is the RE corresponding to the CSI-RS with 4 ports on the 9/10 th symbol in the RB pair, or a bitmap of 3 indicates that the RE corresponding to the RP-RS is the RE corresponding to the CSI-RS with 8 ports on the 9/10 th symbol in the RB pair. Or the corresponding relation between the RP-RS port and the RE combination on the time-frequency resource block may be indicated by using an index (hereinafter referred to as index), where the indication information of each Nbit indicates a resource corresponding to the RP-RS or a RE corresponding to one port. For example, the index number of 5 bits is used to indicate that the RE corresponding to the RP-RS is the RE corresponding to which CSI-RS with 2 ports corresponds, or the index number of 4 bits is used to indicate that the RE corresponding to the RP-RS is the RE corresponding to which CSI-RS with 2 ports on 9/10 th symbols in the RB pair. Further, when the transmitter informs the receiver which RP-RS port to use for power measurement, it can adopt

Wherein

The rounding-up is performed on x, M is the number of the RP-RS ports which are notified to the receiver before, and M can also be obtained by summarizing all the RP-RS ports of a cell or a node. One RP-RS port is indicated by each N-bit indication information, so that a receiver can determine on which RP-RS port to perform power measurement according to each N-bit indication information. Or a port number is arranged for each RP-RS port, and the port number of the RP-RS port used for measuring the power is informed.

A sixth mode is that the transmitter sends two notification messages to the receiver, namely a first notification message and a second notification message, wherein the first notification message contains the binding relationship between the RP-RS port and all or part of REs of the RS port or the binding relationship between the RP-RS port and all or part of REs of the RS resource; the second notification message contains the RP-RS port and the measurement type information.

The binding relationship may be indicated by bitmap mapping or index number.

The RP-RS resource information can include the number of RP-RS ports corresponding to the RP-RS resource, the corresponding relation between each RS port and the resource unit on the time-frequency resource block, the subframe period and the offset position in the subframe period of the RP-RS resource, the frequency band position information of the RP-RS resource, and the like.

Herein, the RP-RS may be a CRS, a CSI-RS, a PRS, an MBSFN RS, a UE-Specific RS, an SRS, and the RP-RS resource may include reference signal resources for one or more of the same or different types of reference signals described above.

Taking the RP-RS as an example of the CSI-RS, one CSI-RS resource may include 4 ports, and each time-frequency resource block for transmitting the CSI-RS resource uses a certain pattern to determine a correspondence between each port and a resource unit on the time-frequency resource block, where the time-frequency resource block may be an RB pair (resource block pair).

In one embodiment, the attribute information of the reference power reference signal port includes time domain periodicity information and position offset information within a periodicity, the subframe periodicity size of the CSI-RS resource is 5 subframes, and a corresponding CSI-RS, i.e., the RP-RS, is transmitted in the 1 st subframe (offset position within a subframe periodicity) of each periodicity.

In an embodiment, the attribute information of the reference power reference signal port includes subband position information or band position information of a frequency domain, and the band position of the CSI-RS resource may be all subbands or several subbands of the entire system bandwidth, that is, the pattern is applied to RB patterns of all subbands or several subbands to determine the correspondence between each port and a resource unit on a time-frequency resource block.

An RP-RS port is fully or partially bound to at least one port in an RS resource if the RP-RS port is fully or partially bound to a type of RS port, where RS may be CRS, CSI-RS, PRS, MBSFN RS, UE-Specific RS, SRS.

For example, the first notification message includes a binding relationship between the RP-RS port and all or part of CSI-RS ports of the CSI-RS resource, or a binding relationship between the RP-RS port and all or part of CRS ports of the CRS resource, or a binding relationship between the RP-RS port and all or part of resource units of the CSI-RS resource, or a binding relationship between the RP-RS port and all or part of resource units of the CRS resource; the second notification message includes the reference power reference signal port and the measurement type information.

In this way, the resource corresponding to the RP-RS may be defined by a CSI-RS port, a CSI-RS resource, a CRS port or a CRS resource, a PRS port, an MBSFN RS port, a UE-Specific RS port, a RE resource corresponding to the PDCCH, a RE resource corresponding to the PDSCH, and a RE corresponding to the SRS port and the SRS resource. For example, assuming that the RP-RS resource includes 2 RP-RS ports and a certain CSI-RS resource includes 4 CSI-RS ports, in this way, the RP-RS port0 may be bound to two CSI-RS ports of the 4 CSI-RS ports, and the RP-RS port1 may be bound to the other two CSI-RS ports of the 4 CSI-RS ports. Therefore, when informing the receiver of what measurement is performed on which RP-RS port or ports, the transmitter only needs to inform the RP-RS port and the measurement type information, instead of informing the corresponding relationship between the RP-RS port and the RE combination and the attribute information of the RP-RS port, for example, informing the receiver of RSRP measurement using RP-RS port 1.

On the basis, the attribute information of the RP-RS port corresponding to the receiver can be simultaneously notified, at the moment, the RP-RS port corresponds to a part of port of a certain RS resource or a certain RS resource, and the receiver receives the RP-RS according to the notified attribute information of the RP-RS port instead of the attribute information of the port of the RS. At this time, the correspondence between the RP-RS port and a part of ports of a certain RS resource or a certain RS resource may be that the period of the RP-RS port is different from the period of the ports of the bound RS resource or the period of the RS resource, for example, the period of the RP-RS port is a multiple of the period of the bound RS resource; or the band position of the RP-RS port is different from the band position of the ports or RS resources of the bonded RS resources, e.g., the band position of the RP-RS port is the central 6 RBs or 72 subcarriers of the entire system bandwidth regardless of the band position of the bonded ports or resources. The scrambling code information or sequence information of the RP-RS port may also be different from the bound port or resource, for example, the notified scrambling code information or sequence information of the RP-RS port is orthogonal to the scrambling code corresponding to the bound port or resource.

Based on the transmitter notifying the receiver in this way, correspondingly, the receiver can receive the first notification message sent by the transmitter, thereby obtaining the binding relationship between the RP-RS port and the existing CSI-RS port, CRS port, CSI-RS resource or CRS resource, that is, obtaining the corresponding relationship between the RP-RS port and the RE combination and the attribute information of the RP-RS port. Or simultaneously obtaining the attribute information of the RP-RS ports according to the first notification message. The receiver may then receive a second notification message sent by the transmitter to learn what measurements are made on which RP-RS port or ports. Then, the receiver can receive the RP-RS sent by the transmitter on the corresponding transmission resource according to the RP-RS port notified by the second notification message and the binding relationship and attribute information notified by the first notification message, and perform power measurement corresponding to the measurement type information according to the RP-RS.

And the transmitter sends a notification message to the receiver, wherein the notification message comprises the binding relationship between the RP-RS port and all or part of REs of the RS port or the binding relationship between the RP-RS port and all or part of REs of the RS resource, the RP-RS port and the measurement type information

For example, the notification message may include a binding relationship between an RP-RS port and a CSI-RS port, a binding relationship between an RP-RS port and a CRS port, a binding relationship between an RP-RS port and CSI-RS resources, a binding relationship between an RP-RS port and CRS resources, and RP-RS port and measurement type information.

The difference between this method and the sixth method is that the binding relationship, the RP-RS port, and the measurement type information are all notified to the receiver in one message. Similar to the sixth way, if the RP-RS port is bound with a part of REs of the RS port or bound with a part of REs of the RS resource, the transmitter further notifies the receiver of the attribute information of the RP-RS port, such as time domain position information and frequency domain position information of the RP-RS port.

Based on the transmitter, the receiver is informed in the manner, accordingly, the receiver can receive the RP-RS sent by the transmitter on the corresponding transmission resource according to the informed RP-RS port and the informed binding relationship, and perform power measurement corresponding to the measurement type information according to the RP-RS. If the RP-RS port is bound with part of the REs of the RS port or bound with part of the REs of the RS resource, the receiver can receive the RP-RS sent by the transmitter on the corresponding transmission resource according to the RP-RS port, the binding relation and the attribute information of the RP-RS port notified by the transmitter, and carry out power measurement corresponding to the measurement type information according to the RP-RS.

In the sixth or seventh mode, each RP-RS port may correspond to a CSI-RS resource of 1/2 ports, and there are 32 ports, so that the transmitter may notify the receiver of available RP-RS ports by using a 32-bit bitmap, and when the transmitter notifies the receiver of performing power measurement, the receiver may be notified by using 5 bits of the available RP-RS ports to perform what measurement is performed by using which RP-RS port of the 32 RP-RS ports.

It should be noted that the transmitter may notify one or more RP-RS ports when notifying the receiver of available RP-RS ports, and may also notify one or more RP-RS ports when subsequently notifying the receiver of what measurement can be performed on which RP-RS port. For example, the transmitter may notify the receiver of available 5 RP-RS ports, and the notification enables the receiver to know all information of the 5 RP-RS ports, such as RE resources corresponding to the RP-RS ports on a time-frequency resource block, time-domain location information of the RE resources, frequency-domain location information of the RE resources, and the like. When the subsequent transmitter needs the receiver to perform CQI measurement, the transmitter may notify the receiver to perform measurement of valid signal or interference signal of CQI on 2 RP-RS ports, and the final measurement result may obtain an average value of power for the measurement on the 2 RP-RS ports, for example. Or informing the effective signal or interference signal measurement of the CQI on one RP-RS port, and using the measured power value for the calculation of the CQI after the measurement by the receiver.

In the network, in order for the receiver to be able to detect correct power information, the network side may correspondingly transmit a certain signal on the transmission resource of the RP-RS port for measuring power by the receiver on all or part of the network nodes on the network side, so as to cooperate with the receiver to perform corresponding power measurement. For example, when the receiver measures interference, all or a part of nodes on the network side may transmit a certain signal on the resource where the corresponding receiver measures interference, so that the receiver may measure the interference of the corresponding node.

The network end is informed of the measurement according to the accuracy of the power measurement and the cost occupied by the RP-RS used for the power measurement, a certain compromise scheme is obtained, and meanwhile, the accuracy requirement of the power measurement and the limit of the cost are met.

The transmitter can transmit anything on the transmission resource corresponding to the RP-RS, and the receiver can only perform power measurement according to the information informed or configured by the transmitter. If the transmitter transmits data on the transmission resource corresponding to the RP-RS, the receiver may also include the data transmitted by the transmitter in the measured interference when the receiver measures interference on the corresponding RP-RS. The processing of the receiver is fully controlled, just by measuring the corresponding power on the corresponding RP-RS, without knowing which node the corresponding RP-RS is transmitting and what the actual signal is transmitted on the RP-RS.

All power measurements, including interference measurements, reference signal related power measurements and new power measurements or interference measurements that may occur in the future, may be measured on a certain RP-RS port.

In this embodiment, the notification may be implemented by high-level signaling such as Radio Resource Control (RRC) or may be one or more fields of physical layer signaling, such as PDCCH and ePDCCH.

After the power measurement is performed in the seven manners, the receiver may calculate feedback information according to the measurement type information and the power measurement result, and send the feedback information to the transmitter, for example, feed back an RSRP measurement result to the transmitter, or feed back a calculated CQI to the transmitter; alternatively, the receiver may perform local power-related processing, such as adjustment of local transmit power, port selection, node selection, and the like, according to the measurement type information and the power measurement result.

The technical solution of the present invention is explained in detail below using two specific examples.

Fig. 2 is a flowchart of a second embodiment of the power measurement method of the present invention, and as shown in fig. 2, the method of this embodiment may include:

step 201, the transmitter informs the receiver of the configuration information of the RP-RS.

For example, the transmitter may determine that the receiver needs to measure two RSRPs, and according to the two RSRPs that need to be measured, may determine that the RP-RS in this embodiment may include two RP-RS ports, i.e., RP-RS port0 and RP-RS port 1. For example, in this embodiment, the RP-RS port0 corresponds to the CSI-RS Config 5 of the 4 ports, and the RP-RS port1 corresponds to the CSI-RS Config 0 of the 4 ports, or the RP-RS port0 corresponds to the CSI-RS Config 5 of the 4 ports, and the RP-RS port1 corresponds to the port 19/20 in the CSI-RS Config 0 of the 8 ports. Therefore, the transmitter can inform the receiver of the configuration information of the RP-RS port0 and the RP-RSport 1, and the configuration information can be the corresponding relation between the RP-RS port0 and the RP-RSport 1 and the CSI-RS port or the RE of the CSI-RS resource.

In a specific implementation, the configuration information may include: a configuration number, a resource number or a port number of the RP-RS port; information of corresponding RE combinations on the time-frequency resource blocks; time domain position information such as time domain period information and position offset information within a period; frequency domain location information, such as corresponding frequency band location information. Optionally, the configuration information may further include: and generating initialization parameter information and transmitting power information by the sequence.

It is understood that the RP-RS port0 and RP-RS port1 in the present embodiment are not limited to REs that both use CSI-RS resources or CSI-RS ports, and as mentioned above, RP-RS port0 and RP-RS port1 may be any combination of all REs that the receiver can decode.

In this embodiment, the notification may be implemented by a higher layer signaling such as RRC, or may be one or several fields of a physical layer signaling such as PDCCH and ePDCCH.

Step 202, the transmitter informs the receiver that the RSRP measurements are respectively performed on the two RP-RS ports.

After receiving the notification from the transmitter, the receiver may determine the REs corresponding to RP-RS port0 and the REs corresponding to RP-RS port1 according to the configuration information obtained in step 201. Then, the receiver can measure the received signal corresponding to the CSI-RS on the RE corresponding to the RP-RS port0, average the power of the received signal corresponding to the CSI-RS on the RE corresponding to the RP-RS port0, such as arithmetic averaging, and quantize the power value obtained after averaging to RSRP as the RSRP measured on the RP-RS port 0. In the same way, the receiver can measure the RSRP corresponding to RP-RS port 1.

And step 203, the receiver feeds back the RSRP measured on the RP-RS port0 and the RP-RS port1 to the transmitter.

The notification of RP-RS in step 201 may be for a certain UE or for a certain cell, while the notification of which measurements are made on which RP-RS port in step 202 may be for a certain UE.

In this embodiment, step 201 and step 202 are notified by using two notification messages to the receiver, and those skilled in the art can understand that, according to the foregoing seven manners, the two notification messages in step 201 and step 202 may also be combined into one notification message for notification, or the notification message in step 201 may also be split into two parts for notification respectively.

In this embodiment, after receiving the notification message that the transmitter performs RSRP measurement on the RP-RS port, the receiver may receive, on the corresponding RE, the RP-RS sent by the transmitter according to the configuration information of the RP-RS, and perform corresponding RSRP measurement. Therefore, in this embodiment, the transmitter may send the RP-RS on the CSI-RS resources or REs on the CSI-RS ports through the configuration information, so that the RE combination may be performed for RSRP measurement, thereby avoiding a situation that some measured RS resources are not enough and some measured RS resources are redundant, and further making RSRP measurement accurate. Moreover, by adopting the technical scheme of the embodiment, the transmitter can flexibly control the process of power measurement of the receiver.

Fig. 3 is a flowchart of a third embodiment of the power measurement method of the present invention, and as shown in fig. 3, the method of this embodiment may include:

step 301, the transmitter informs the receiver of the configuration information of the RP-RS.

For example, the transmitter may determine that the receiver needs to measure two CQIs, and according to the two CQIs that need to be measured, determine to measure the CSI-RS of the effective signal portion, and determine to measure two RP-RS ports corresponding to the interference portion, i.e., RP-RS port0 and RP-RS port 1.

In this embodiment, it is assumed that the signal portions corresponding to the two CQIs are the same, and the interference portions are different. The valid signal part can be measured on REs corresponding to the CSI-RS resources (using CSI-RS Config 1) of the 4 ports. The interference fraction can be measured on RP-RS port0 and RP-RS port 1. Wherein, RP-RS port0 may correspond to RE of CSI-RS Config 0 of 4 ports, RP-RS port1 may correspond to RE of CSI-RS Config 5 of 4 ports, or RP-RS port0 corresponds to RE of CSI-RS Config 0 of 4 ports, RP-RS port1 corresponds to port 19/20 in CSI-RS Config 0 of 8 ports. The RP-RS port also corresponds to certain time domain and frequency domain position information at the same time, for example, the RP-RS port is the same as the time-frequency domain position information of the CSI-RS resource containing the corresponding CSI-RS port.

The transmitter may inform the receiver of both RP-RS ports of the RP-RS through RRC signaling.

Step 302, the transmitter informs the receiver to measure the interference part on two RP-RS ports, and measures the signal part on the CSI-RS resource (using CSI-RS Config 1) of 4 ports.

After receiving the notification from the transmitter, the receiver may determine the REs corresponding to RP-RS port0 and the REs corresponding to RP-RS port1 according to the configuration information obtained in step 301. The receiver can then make interference measurements on both RP-RS ports, respectively, and the measurement of the active signal part on the 4-port CSI-RS Config 1.

Step 303, the receiver calculates two CQIs respectively according to the signal part measured on the CSI-RS resource (using CSI-RS Config 1) and the interference part measured on the two RP-RS ports, and feeds back the two CQIs to the transmitter.

Specifically, the receiver may measure the received signal and the total received signal of the corresponding CSI-RS on the RE corresponding to RP-RS port0, subtract the received signal of the corresponding CSI-RS from the total received signal corresponding to each RE to obtain the interference signal corresponding to the RE, and average the power of the interference signal measured on each RE, for example, arithmetic average, to obtain the interference signal for calculating the corresponding CQI. Also, the receiver may measure the valid signal on the 4-port CSI-RS resource (using CSI-RS Config 1), and finally, the receiver may calculate the corresponding CQI from the valid signal and the interference signal measured on RP-RS port 0.

The receiver can measure the interference signal on RP-RS port1 and the effective signal on the CSI-RS resource of 4 ports (using CSI-RS Config 1) in the same way, and calculate the corresponding CQI. The receiver may feed back these two CQIs to the transmitter.

It should be noted that in this embodiment, two RP-RS ports may also be used to measure the effective signal portion, and other REs are used to measure the interference portion.

In addition, it can be understood by those skilled in the art that step 301 and step 302 in the present embodiment can also be notified to the receiver in the aforementioned seven ways.

In this embodiment, after receiving the notification message about CQI measurement performed on the RP-RS port by the transmitter, the receiver may receive, on the corresponding RE, the reference signal sent by the transmitter according to the configuration information of the RP-RS, and perform interference signal power measurement or effective signal power measurement of the corresponding CQI. Therefore, in this embodiment, the transmitter may send the reference signal on the CSI-RS resource or the RE of the CSI-RS port through the configuration information, so that the RE combination may be performed for the CQI measurement, thereby avoiding a situation that some measured RS resources are not enough and some measured RS resources are redundant, and further making the CQI measurement accurate. Moreover, with the technical solution of this embodiment, the transmitter can flexibly control the process of CQI measurement performed by the receiver.

In another embodiment of the power measurement method of the present invention, the RP-RS port may be associated with an SRS port or an RE of an SRS resource. In this embodiment, one RP-RS port may correspond to one SRS port or to an RE of an SRS resource, and the transmitter may notify the first receiver to measure the received power of the RP-RS on the RP-RS, so as to obtain the received power of the reference signal from the second receiver to the first receiver, which transmits the SRS. This reference signal received power may be used as reference information for communication between the first receiver and the second receiver.

Fig. 4 is a flowchart of a first embodiment of a signal measurement method according to the present invention, and as shown in fig. 4, the method of this embodiment may include:

step 401, obtaining a measurement mode of signal measurement.

And 402, performing signal measurement on the transmission resource corresponding to the signal measurement by adopting the measurement mode.

In particular, in existing communication systems, the resources available for signal measurement may include zero-power CSI-RS or non-zero-power CSI-RS. In some cases, the transmitter may notify the user of multiple CSI-RS resources, and among these resources, a zero-power CSI-RS resource and a non-zero-power CSI-RS resource may use the same RE location or the same CSI-RS configuration number, so that different measurement methods may be adopted when performing signal measurement on corresponding REs. However, in the prior art, the transmitter can only inform the receiver on which resources to measure the signal, but when different measurement methods are needed to perform signal measurement on the same resource, the receiver does not know how to perform signal measurement, so that the problem of inaccurate signal measurement often occurs.

Accordingly, in this embodiment, the receiver may obtain a measurement mode of signal measurement, and then the receiver may perform signal measurement on the transmission resource corresponding to the signal measurement by using the measurement mode.

In this embodiment, before the receiver performs signal measurement, the receiver may obtain a measurement mode of the signal measurement, so as to perform signal measurement on a transmission resource corresponding to the signal measurement by using the measurement mode, thereby making the signal measurement more accurate.

The embodiment of the method shown in fig. 4 is a technical solution implemented by a receiver, and accordingly, for a transmitter, it may send an indication signaling to the receiver, where the indication signaling includes a measurement mode of signal measurement, so that the receiver performs signal measurement on a transmission resource corresponding to the signal measurement by using the measurement mode.

Specifically, the transmitter may send an indication signaling to the receiver to indicate a measurement mode of the signal measurement performed by the receiver, and then the receiver may perform corresponding signal measurement by using the obtained measurement mode.

In this embodiment, the transmitter may instruct the receiver to perform a measurement mode of signal measurement, so that the receiver may perform corresponding signal measurement by using the measurement mode, and further, the signal measurement may be more accurate.

In a specific implementation, for the zero-power CSI-RS, the corresponding measurement manner may be to perform signal measurement on the received signal as a signal for performing direct measurement, and for the non-zero-power CSI-RS, the corresponding measurement manner may be to perform signal measurement on a signal obtained by subtracting a decodable portion (e.g., a corresponding signal of the non-zero-power CSI-RS) from the received signal as a signal for performing direct measurement; or, for the zero-power CSI-RS, the corresponding measurement method may be to perform signal measurement using the transmission resource as a zero-power reference signal, and for the non-zero-power CSI-RS, the corresponding measurement method may be to perform signal measurement using the transmission resource as a non-zero-power reference signal. The transmitter may also, upon notification of the transmission resource, notify whether to use the transmission resource as a zero power reference signal, e.g., for signal measurement, or as a non-zero power reference signal, e.g., for signal measurement. Wherein the non-zero power reference signal may include: RE corresponding to a CSI-RS port, RE corresponding to a CSI-RS resource, RE corresponding to a CRS port, RE corresponding to a CRS resource, RE corresponding to a PRS port, RE corresponding to an MBSFN RS port, RE corresponding to a UE-Specific RS port, RP-RS, RE corresponding to an SRS port or any combination of RE corresponding to SRS resources.

The transmitter may cause the receiver to obtain the measurement mode by sending an indication signaling. In a specific implementation, the indication signaling may include a 1-bit indication bit, and the two states represented by the indication bit may be respectively used to represent a measurement mode in which the received signal is used as a signal to be directly measured and a measurement mode in which a signal obtained by subtracting a decodable portion from the received signal is used as a signal to be directly measured; or respectively represent a measurement mode with the transmission resource as a zero power reference signal and a measurement mode with the transmission resource as a non-zero power reference signal. Alternatively, the indication signaling may also include an indication bit of Nbit,wherein

Indicating that x is rounded up, M is the number of corresponding CSI-RSs on the same RE of the notification receiver, and 2 of the indicator bit^NEach state is used for representingA measurement mode for performing signal measurement on different reference signals on the same transmission resource, for example, when each indicator bit represents measurement interference, a received signal of the reference signal corresponding to the indicator bit needs to be subtracted from a total received signal; or N is equal to the number of reference signals corresponding to the same transmission resource, and each bit is used to identify a measurement mode for performing signal measurement according to the reference signal on the transmission resource corresponding to the bit, such as subtracting all received signals corresponding to the reference signals with bit 1 from the total received signal when interference is measured.

Another measurement method of this embodiment may be to descramble the received signal by using a scrambling code orthogonal to or the same as the scrambling code scrambled by the transmitter, and use the descrambled signal as the signal to be directly measured.

Specifically, the transmitter may notify the receiver of a scrambling code used for descrambling, which is not necessarily the same as the scrambling code used for scrambling the signal by the transmitter, and a specific notification manner may be to generate the initialization parameter for the notification sequence. When the descrambled scrambling code notified by the transmitter is orthogonal to the scrambled scrambling code, and a signal obtained by descrambling a received signal, for example, a signal measured on an RE corresponding to the CSI-RS, is averaged by the receiver, the portion corresponding to the CSI-RS is zero or approximately equal to zero after being accumulated, so that only signal power or interference power other than the CSI-RS remains. For example, one RP-RS port corresponds to one CSI-RS port, and the scrambling code used by the transmitter for scrambling is X₁，X₂，…，X_NIf the transmitter informs the receiver that the descrambling scrambling code used is Y₁，Y₂，…，Y_NWhere Σ (X)₁×Y₁) If the measured power of the RP-RS port is equal to or greater than 0, that is, the scrambled scrambling code is orthogonal to the decoded scrambling code, then when the receiver accumulates the measured signal on the RP-RS port after descrambling, the signal portion corresponding to the CSI-RS is accumulated to zero or approximately equal to zero, so that the measured power does not include the power of the corresponding CSI-RS, that is, the descrambled signal is used as a signal for direct measurement.

The signal measurement described in the embodiment of fig. 4 may be a power measurement or an interference measurement. The interference measurement may be a power measurement of the interference or a covariance matrix measurement of the interference.

The following describes the interference measurement procedure performed by the transmitter and receiver interaction in a specific embodiment.

Fig. 5 is a flowchart of a second embodiment of the signal measurement method of the present invention, and as shown in fig. 5, the method of this embodiment may include:

step 501, the transmitter informs the receiver of the CQI to be fed back and informs the receiver of the interference measurement mode on the interference measurement resource.

For example, the transmitter may inform the receiver that the CSI-RS resource is a non-zero power CSI-RS resource and at the same time inform that the CSI-RS resource is a zero power CSI-RS resource.

When the transmitter notifies the receiver of the CQI that needs to be fed back, the receiver may be notified to measure an interference signal on the CSI-RS resource in two measurement manners, one interference signal is to directly measure a total received signal on the CSI-RS resource as an interference signal to calculate the CQI (one node in a corresponding cell serves the receiver), and the other interference signal is to calculate another CQI (another node in a corresponding cell serves the receiver) by subtracting the received corresponding CSI-RS signal from the total received signal on the CSI-RS resource as an interference signal.

Step 502, the receiver uses the corresponding interference measurement mode to measure on the interference measurement resource, and calculates the corresponding CQI.

If the interference measurement method notified by the transmitter is to perform interference measurement using a directly measured received signal as an interference signal or using the resource as a zero-power resource, the receiver may directly perform calculation of the corresponding CQI using signals measured on all REs corresponding to the resource as interference signals.

If the interference measurement method notified by the transmitter is to subtract the RS received on the corresponding resource from the received total signal and then use the subtracted RS as an interference signal or use the resource as a non-zero power resource for interference measurement, the receiver may subtract the RS received on the corresponding resource from the received total signal and then use the remaining signal as an interference signal for calculation of the corresponding CQI.

Step 503, the receiver feeds back the CQI to the transmitter.

In this embodiment, the receiver may be notified of the measurement mode of the interference measurement by the transmitter before the interference measurement is performed, so that after the signal sent by the transmitter is received on the transmission resource corresponding to the interference measurement, the received signal may be subjected to the interference measurement by using the corresponding measurement mode, and thus, a more accurate CQI may be obtained by using a correct measurement mode.
