FIG. 1 is a schematic flowchart of a CSI measurement method according to an embodiment of the present application, as shown in FIG. 1 . 101. Receive resource configuration information sent by a base station for downlink data transmission and/or measurement information used for measurement.

 102. Determine, according to the resource configuration information and/or the measurement information, a measured subband resource in at least one subframe.

 103. Perform CSI measurement on the determined measurement subband resource.

 The CSI is composed of a Precoding Matrix Indicator (PMI) and a Channel Quality Indicator (CQI).

 Optionally, the CSI may further include a rank indicator (R1). It should be noted that the execution body of the foregoing 101-103 may be a terminal, may be an ordinary terminal capable of supporting system bandwidth, or may be an MTC terminal capable of supporting a part of bandwidth in the system bandwidth.

 It should be noted that the system bandwidth can be divided into several sub-band resources (sub-bands). In a sub-frame, each sub-band resource is a resource that includes a plurality of resource blocks (RBs), and the number of RBs included in each sub-band resource indicated by the resource configuration information is indicated by the measurement information. The number of RBs included in each subband resource may be inconsistent.

 Optionally, in a possible implementation manner of this embodiment, in 101, the resource configuration information sent by the base station for downlink data transmission and the measurement information used for measurement may be specifically received. Then, in the subframe corresponding to the sub-band resource indicated by the measurement information, if the sub-band resource indicated by the resource configuration information and the sub-band resource indicated by the measurement information, The sub-band resource indicated by the measurement information is a measurement sub-band resource in the sub-frame, and the bandwidth that the terminal can support is part of the system bandwidth; or If the sub-band resource indicated by the resource configuration information and the sub-band resource indicated by the measurement information are more than a bandwidth that the terminal can support, in a subframe corresponding to the sub-band resource indicated by the measurement information, And determining, by the sub-band resource indicated by the measurement information, a measurement sub-band resource in the subframe, or performing an operation of determining a measurement sub-band resource in the at least one subframe, where the bandwidth that the terminal can support is Part of the system bandwidth.

It should be noted that, in a subframe corresponding to the subband resource indicated by the measurement information, if a union of the subband resource indicated by the resource configuration information and the subband resource indicated by the measurement information exceeds The bandwidth that the terminal can support, determining that the sub-band resource indicated by the measurement information is a measured sub-band resource in the subframe, or not performing determining the measured sub-band resource in the at least one subframe Operations can operate based on pre-configured priorities of the system. For example, when data is received or transmitted

When the CSI measurement is more important, the system may set the operation of not performing the measurement subband resource in the at least one subframe to a high priority; conversely, if the CSI measurement is more important than the data reception or transmission, the system may determine the location The sub-band resource indicated by the measurement information is set to a high priority for the measured sub-band resource in the subframe.

 For example, FIG. 2A is a schematic diagram of a subband resource indicated by resource configuration information in six subframes in the embodiment corresponding to FIG. 1, and FIG. 2B is a measurement indicated by measurement information in six subframes in the embodiment corresponding to FIG. Schematic diagram of the subband resource.

 It is assumed that the bandwidth that the terminal can support is one sub-band, and the subframe corresponding to the sub-band resource indicated by the measurement information is the second subframe, the fourth subframe, and the sixth subframe, then, in the second In the sub-frame, the sub-band resource indicated by the resource configuration information is sub-band 1 , and the sub-band resource indicated by the measurement information is sub-band 1 , and the union of the two does not exceed the bandwidth that the terminal can support, and the terminal can determine The sub-band 1 is a measurement sub-band resource in the second sub-frame, as shown in FIG. 2C. In the fourth sub-frame, the sub-band resource indicated by the resource configuration information is sub-band 4, and the sub-band indicated by the measurement information The resource is subband 3, and the union of the two exceeds the bandwidth that the terminal can support. The terminal can determine the subband 3 indicated by the measurement information as the measured subband resource in the fourth subframe according to the pre-configured priority. As shown in FIG. 2C, or alternatively, the operation of determining the measured subband resource in the fourth subframe is not performed, and the subband resource is not measured in the fourth subframe.

 In the sixth subframe, the sub-band resource indicated by the resource configuration information is the sub-band 3, and the sub-band resource indicated by the measurement information is the sub-band 4, and the convergence of the two exceeds the bandwidth that the terminal can support, and the terminal can Determining, according to the pre-configured priority, the sub-band 4 indicated by the measurement information is a measurement sub-band resource in the sixth sub-frame, as shown in FIG. 2C, or determining not to measure the sub-band in the sixth sub-frame. The operation of the resource does not measure the subband resources in the sixth subframe.

 Optionally, in a possible implementation manner of this embodiment, in 101, the resource configuration information sent by the base station for downlink data transmission may be specifically received. Then, correspondingly, in 102, the indication information is further obtained, where the indication information is used to indicate a sub-band resource in the sub-band resource indicated by the resource configuration information, and then Determining the measured subband resource by using the resource configuration information and the indication information.

For example, FIG. 2A is a schematic diagram of a sub-band resource indicated by resource configuration information in six subframes in the embodiment corresponding to FIG. 1, and the indication information indicates a sub-instruction indicated by the resource configuration information. The sub-band resource in the resource group is the sub-band in the even-numbered subframes in the sub-frame corresponding to the sub-band indicated by the resource configuration information, and the terminal may follow the sub-band according to the sub-frame indicated by the resource configuration information. The order is sub-band 3, sub-band 1, sub-band 2, sub-band 4, sub-band 5, and sub-band 3, and the indication information, determining that the measured sub-band resource is sub-band 1 in the second sub-frame , subband 4 in the fourth subframe and subband 3 in the sixth subframe, as shown in FIG. 2D.

 Assume that the sub-band resource other than the sub-band resource indicated by the resource configuration information is offset downward by one sub-band for the sub-band indicated by the resource configuration information, and the terminal may be configured according to the resource configuration information. The indicated sub-bands are sub-band 3, sub-band 1, sub-band 2, sub-band 4, sub-band 5, and sub-band 3 in the order of the sub-frames, and the indication information, determining the measured sub-band resources according to the sub-frame order In turn, subband 4, subband 2, subband 3, subband 5, subband 6 and subband 4 are shown in Fig. 2E.

 Assume that the indication information indicates that the sub-band resources other than the sub-band resources indicated by the resource configuration information are offset downward by one sub-band in an even number of subframes corresponding to the sub-band indicated by the resource configuration information. Sub-band, the terminal may sequentially sub-band 3, sub-band 1, sub-band 2, sub-band 4, sub-band 5, and sub-band 3 according to the sub-frame indicated by the resource configuration information, and the indication Information, determining that the measured subband resource is a subband 2 in a second subframe, a subband 5 in a fourth subframe, and a subband 4 in a sixth subframe, as shown in FIG. 2F.

 Optionally, the terminal may further receive the indication information sent by the base station. Specifically, the terminal may specifically receive the indication information that is sent by the base station by using high layer signaling.

 For example, the high layer signaling may be radio resource control (Radio Resource Control,

The RRC message may be carried by the information element (IE) in the RRC message, where the RRC message may be an RRC message in the prior art, for example, RRC CONNECTION RECONFIGURATION The message and the like are not limited in this embodiment. The IE message is extended by the IE of the existing RRC message, or the RRC message may be different from the RRC message existing in the prior art.

 For example, the high-level signaling may be a Media Access Control (MAC) Control Element (CE) message, and the indication information may be carried by adding a new MAC CE message.

It can be understood that the specific examples of the high-level signaling that appear later can be similarly performed in the above examples, and will not be described again in the future. Optionally, the indication information may be pre-configured by the system (for example, a protocol agreement), and the terminal may further obtain the indication information according to the system pre-configuration.

 Optionally, in a possible implementation manner of this embodiment, in 101, the measurement information sent by the base station for measurement may be specifically received.

 For example, FIG. 2B is a schematic diagram of a subband resource indicated by measurement information in six subframes in the embodiment corresponding to FIG. 1, and the terminal may be in the second subframe according to the subband resource indicated by the measurement information. Subband 2, subband 3 in the fourth sub-frame, and sub-band 4 in the sixth sub-frame, then determining the measured sub-band resource as sub-band 2 in the second sub-frame Subband 3 within four subframes and subband 4 within the sixth subframe.

 Optionally, in step 102, the determined measurement subband resource in the at least one subframe may be periodically applied to a subsequent subframe, where the at least one subframe is a period of the measured subband resource.

 Optionally, in a possible implementation manner of the embodiment, after the terminal, the terminal may further report, to the base station, all subbands that have been measured in more than one subframe in one subframe in which the reporting time is located. CSI or CSI of the middle molecular band of all sub-bands.

 It should be noted that the reporting time may be determined in a periodic manner or in a non-cyclic manner. The determining manner of the terminal reporting time may be obtained by high layer signaling.

 For example, the determining the reporting time in a periodic manner may be that the terminal allocates a certain reporting period and an offset value by using the high layer signaling, and the terminal calculates the reporting time by using the reporting period and the offset value.

 Optionally, the reporting period may be greater than a reporting period in the prior art.

 Optionally, the reporting period and the offset value of the CQI, the PMI, and the RI may be separately configured, and the reporting period and the offset value of the three may be different.

 For example, determining the reporting time in a non-period manner may be determined by a bit trigger carried in a Physical Downlink Control Channel (PDCCH), or may be determined by a bit trigger carried in a random access response. If the trigger information is detected in the nth (n is an integer greater than or equal to 0) subframes, it is determined that the reporting time is the n+k (n is an integer greater than 0) subframes.

 In this embodiment, the reporting of the terminal CSI can be implemented in multiple manners, that is, multiple reporting modes. The selection of the terminal reporting mode can be obtained through high layer signaling.

It should be noted that the CSI of one sub-band in the CSI of the sub-band reported by the terminal may be obtained by measuring the sub-band in one sub-frame, or may be in different sub-frames. The average of the results of the measurement of the sub-band.

 Optionally, in a possible implementation manner of the embodiment, the terminal may report, to the base station, all subbands that have been measured in more than one subframe in one subframe that is in the last time.

CSI, as shown in Figure 2G. The CSI of all subbands that have been measured refers to the CSI measured in the subframe between the subframes in the two adjacent reporting instants. At the reporting time 1, the CSIs of all subbands that have been measured include the CSI of subband 1, the CSI of subband 2, and the CSI of subband 3 in the order of the subframes. At the reporting time 2, the CSI of all subbands that have been measured The CSI of the sub-band 4, the CSI of the sub-band 5, and the CSI of the sub-band 3 are sequentially included in the order of the subframe. Alternatively, the CSI of the sub-band 3 measured in the two sub-frames may also be averaged.

 It can be understood that the terminal can also only clamp the CSI of the measured sub-band in one subframe to the base station in one subframe in which the reporting time is located.

 Optionally, in a possible implementation manner of the embodiment, the terminal reports, to the base station, all subbands that have been measured in more than one subframe in a subframe in which the last time is located, and is optimal.

M (M is an integer greater than 0) CSI of subbands. The meaning of the optimal M (M is an integer greater than 0) subbands means that the channel quality indicated by the Channel Quality Indicator (CQI) is sorted from good to bad, and the first M CQIs are corresponding. The subband is the optimal M (M is an integer greater than 0) subbands. The value of M can be preset by the system or configured by higher layer signaling. As shown in Fig. 2G, the measured CSI of all sub-bands refers to the CSI measured in the subframe between the subframes in which two adjacent reporting times are located. At the reporting time 1, the CSIs of all subbands that have been measured include the CSI of subband 1, the CSI of subband 2, and the CSI of subband 3 in the order of the subframe. At the reporting time 2, the measured CSI of all subbands The CSI of the sub-band 4, the CSI of the sub-band 5, and the CSI of the sub-band 3 are sequentially included in the order of the subframe. If M=2 is set, after comparison, at the reporting time 1, the CSI of the optimal sub-band 2 and the CSI of the sub-band 3 in the CSI of all sub-bands are reported; at the reporting time 2, all the measured sub-reports are reported. The CSI of the optimal subband 4 and the CSI of the subband 5 in the CSI of the band.

 It can be understood that the terminal can report only the CSI of the measured sub-band in one subframe to the base station in one subframe of the reporting time.

Optionally, in a possible implementation manner of the embodiment, the terminal reports the measured CSI to the base station in turn in the sub-band sequence indicated by the measurement sub-band resource in one subframe where the time is located. As shown in FIG. 2G, the subbands indicated by the measurement subband resource are sequentially in the order of the subframe. Subband 1, subband 2, subband 3, subband 4, subband 5, subband 3, at the time of reporting, sequentially reporting all subbands that have been measured according to the subbands indicated by the measured subband resource The CSI, for example, reports the CSI of the sub-band 1 at the reporting time 1; the CSI of the sub-band 2 at the reporting time 2, and so on.

 After obtaining the CSI reported by the terminal, the base station may update the resource configuration information and/or the measurement information according to the obtained CSI reported by the terminal, that is, update the resource configuration information at the next resource allocation and/or next time. Measurement information at the time of measurement.

 For example, suppose the system bandwidth has a total of 4 subbands numbered 1, 2, 3, and 4. In the first period (assuming that the period includes 4 subframes), the subband resources indicated by the resource configuration information are subband 1, subband 1, subband 2, and subband 2 in the order of the subframe, as indicated by the measurement information. The subband resources are subband 2, subband 2, subband 3, and subband 3 in order of subframe order. The terminal determines, according to the resource configuration information and the measurement information, that the measured subband resource is a subband within a first subframe, a subband within a second subframe, a subband 3 within a third subframe, and Subband 3 in the fourth sub-frame. Then, the terminal performs CSI measurement on the measured sub-band resource, and sends the measurement result to the base station. According to the measurement result, if the sub-band 2 and the sub-band 3 are found to be suitable for the terminal, the base station may sequentially update the sub-band resources indicated by the resource configuration information into sub-bands 2 and sub-bands in a sub-frame sequence. 2. Subband 3 and subband 3. However, after a period of time, if the base station finds that subband 2 and subband 3 are no longer suitable for the terminal, then a new measurement information can be redefined to indicate the new subband resource, and then, according to the measurement result, The sub-band resource indicated by the resource configuration information is updated.

 In addition, the base station may further update the related configuration of the MCS and the MIMO according to the obtained CSI reported by the terminal.

 In this embodiment, the resource configuration information for downlink data transmission and/or the measurement information for measurement sent by the base station is received, and then determined according to the resource configuration information and/or the measurement information, in at least one subframe. The measurement subband resource within the network enables CSI measurement on the determined measurement subband resource, and enables the MTC terminal to measure CSI.

 FIG. 3 is a schematic flowchart of a CSI measurement method according to another embodiment of the present application, as shown in FIG. 3.

Send the resource configuration information and/or the measurement information to a terminal, so that the end The determining, according to the resource configuration information and/or the measurement information, the measurement subband resource in the at least one subframe, and performing CSI measurement on the determined measurement subband resource.

 The CSI is composed of a Precoding Matrix Indicator (PMI) and a Channel Quality Indicator (CQI).

 Optionally, the CSI may further include a rank indicator (R1). It should be noted that the executor of the foregoing 301-302 may be a base station, where the terminal involved may be an ordinary terminal capable of supporting system bandwidth, or may be an MTC terminal capable of supporting a part of bandwidth in the system bandwidth.

 It should be noted that the system bandwidth can be divided into several sub-band resources. In a sub-frame, each sub-band resource is a resource that includes a plurality of resource blocks (RBs), and the number of RBs included in each sub-band resource indicated by the resource configuration information is indicated by the measurement information. The number of RBs included in each subband resource may be inconsistent.

 It should be noted that, the terminal, according to the resource configuration information and/or the measurement information, that the measurement sub-band resource in the at least one subframe is detailed, may refer to related content in the embodiment corresponding to FIG. I will not repeat them here.

 Optionally, in a possible implementation manner of the embodiment, the base station may further send the indication information to the terminal, so that the terminal determines the measurement component according to the resource configuration information and the indication information. With the resource, the indication information is used to indicate a sub-band resource in or out of the sub-band resource indicated by the resource configuration information. For details, refer to related content in the embodiment corresponding to FIG. 1, and details are not described herein again.

 Specifically, the base station may specifically send the indication information to the terminal by using high layer signaling. For example, the high-level signaling may be a radio resource control (RRC) message, and the indication information may be carried by an information element (IE) in an RRC message, where the RRC message may be existing. The RRC message in the technology, for example, the RRC CONNECTION RECONFIGURATION message, is not limited in this embodiment, and the indication information or the RRC is carried by extending the IE of the existing RRC message. The message may also be different from the RRC messages already available in the prior art.

For example, the high-level signaling may be a Media Access Control (MAC) Control Element (CE) message, and the indication information may be carried by adding a new MAC CE message. Optionally, the base station may not send the indication information to the terminal, where the indication information may be pre-configured by the system (for example, a protocol agreement), and the terminal may further obtain the indication information according to the system pre-configuration.

 Optionally, in a possible implementation manner of the embodiment, after the 302, the base station may further receive, in a subframe in which the reporting time is reported, the terminal is measured in more than one subframe. CSI of all subbands or CSI of the middle molecular band of all subbands. For details, refer to related content in the embodiment corresponding to FIG. 1, and details are not described herein again.

 Optionally, in a possible implementation manner of the embodiment, after the base station obtains the CSI reported by the terminal, the base station may update the resource configuration information and/or the measurement information according to the obtained CSI reported by the terminal. That is, the resource configuration information at the time of the next resource allocation and/or the measurement information at the next measurement is updated.

 For example, suppose the system bandwidth has a total of 4 subbands numbered 1, 2, 3, and 4. In the first period (assuming that the period includes 4 subframes), the subband resources indicated by the resource configuration information are subband 1, subband 1, subband 2, and subband 2 in the order of the subframe, as indicated by the measurement information. The subband resources are subband 2, subband 2, subband 3, and subband 3 in order of subframe order. The terminal determines, according to the resource configuration information and the measurement information, that the measured subband resource is a subband within a first subframe, a subband within a second subframe, a subband 3 within a third subframe, and Subband 3 in the fourth sub-frame. Then, the terminal performs CSI measurement on the measured sub-band resource, and sends the measurement result to the base station. According to the measurement result, if the sub-band 2 and the sub-band 3 are found to be suitable for the terminal, the base station may sequentially update the sub-band resources indicated by the resource configuration information into sub-bands 2 and sub-bands in a sub-frame sequence. 2. Subband 3 and subband 3. However, after a period of time, if the base station finds that subband 2 and subband 3 are no longer suitable for the terminal, then a new measurement information can be redefined to indicate the new subband resource, and then, according to the measurement result, The sub-band resource indicated by the resource configuration information is updated.

 In addition, the base station may further update the MCS according to the obtained CSI reported by the terminal.
