Technical scheme, can apply to the wireless communication systems such as LTE system or lte-a system.Terminal therein can be the user equipment (User Equipment, UE) in LTE system or lte-a system；Base station therein can be the eNB in LTE system or lte-a system.

The schematic flow sheet for the CSI measurement method that Fig. 1 provides for the embodiment of the application one, as shown in Figure 1. 101st, the resource allocation information for downlink data transmission and/or the metrical information for measurement that base station is sent are received.

102nd, according to the resource allocation information and/or the metrical information, it is determined that the measurement sub-band resources at least one subframe.

103rd, it is determined that the measurement sub-band resources on, carry out CSI measurements.

Wherein, the CSI indicates (Channel Quality Indicator, CQI) composition by pre-coding matrix instruction (Precoding Matrix Indicator, PMI) and channel quality.

Alternatively, the CSI can further include order instruction（ Rank Indicator, Rl ) .It should be noted that above-mentioned 101 ~ 103 executive agent can be terminal, can also be able to be that can support the MTC terminal of a part of bandwidth in system bandwidth for the ordinary terminal of system bandwidth can be supported.

It should be noted that system bandwidth can be divided into several sub-band resources（Subband）.In a sub- frame in, each sub-band resources are to include several resource blocks（Resource Block, RB) resource, the RB numbers that the RB numbers that each sub-band resources indicated by the resource allocation information are included are included with each sub-band resources indicated by the metrical information can be with inconsistent.

Alternatively, in a possible implementation of the present embodiment, in 101, the resource allocation information for downlink data transmission and the metrical information for measurement of base station transmission can specifically be received.So, correspondingly, in 102, in the subframe corresponding to the sub-band resources indicated by the metrical information, if the union of the sub-band resources indicated by the resource allocation information and the sub-band resources indicated by the metrical information is no more than the bandwidth that terminal can be supported, it is the measurement sub-band resources in the subframe, a part for a width of system bandwidth of band that the terminal can be supported then to determine the sub-band resources indicated by the metrical information；Or in the subframe corresponding to the sub-band resources indicated by the metrical information, if the union of the sub-band resources indicated by the resource allocation information and the sub-band resources indicated by the metrical information exceedes the bandwidth that terminal can be supported, it is the measurement sub-band resources in the subframe then to determine the sub-band resources indicated by the metrical information, or do not perform the operation for determining the measurement sub-band resources at least one subframe, a part for a width of system bandwidth of band that the terminal can be supported.

It should be noted that, in the subframe corresponding to the sub-band resources indicated by the metrical information, if the union of the sub-band resources indicated by the resource allocation information and the sub-band resources indicated by the metrical information exceedes the bandwidth that terminal can be supported, it is the measurement sub-band resources in the subframe to determine the sub-band resources indicated by the metrical information, or does not perform measurement sub-band resources of the determination at least one subframe The priority that operating can be pre-configured with according to system is operated.For example, when data receiver or transfer ratio

When CSI measurements are more important, system, which will can not performed, determines the operation setting of the measurement sub-band resources at least one subframe for high priority；If conversely, when CSI measurements are than data receiver or more important transmission, system can will determine that the sub-band resources indicated by the metrical information are set to high priority for the measurement sub-band resources in the subframe.

For example, Fig. 2A is the pattern schematic diagram in the corresponding embodiments of Fig. 1 in the sub-band resources indicated by 6 sub- frame in resource allocation informations, and Fig. 2 B are the pattern schematic diagram in the corresponding embodiments of Fig. 1 in the sub-band resources indicated by 6 sub- frame in metrical informations.

Assuming that a width of subband of band that the terminal can be supported, because the subframe corresponding to the sub-band resources indicated by the metrical information is second subframe, the 4th subframe and the 6th subframe, so, in second sub- frame in, sub-band resources indicated by resource allocation information are subband 1, sub-band resources indicated by the metrical information are subband 1, the union of the two is no more than the bandwidth that terminal can be supported, terminal can then determine measurement sub-band resources of the subband 1 for second sub- frame in, as shown in Figure 2 C；In the 4th sub- frame in, sub-band resources indicated by resource allocation information are subband 4, sub-band resources indicated by the metrical information are subband 3, the two union exceedes the bandwidth that terminal can be supported, terminal then can be according to the priority being pre-configured with, determine measurement sub-band resources of the subband 3 indicated by the metrical information for the 4th sub- frame in, as shown in Figure 2 C, or, the operation for the measurement sub-band resources for determining the 4th sub- frame in is not performed, sub-band resources are not measured in the 4th sub- frame in.

In the 6th sub- frame in, sub-band resources indicated by resource allocation information are subband 3, sub-band resources indicated by the metrical information are subband 4, the two union exceedes the bandwidth that terminal can be supported, terminal then can be according to the priority being pre-configured with, determine measurement sub-band resources of the subband 4 indicated by the metrical information for the 6th sub- frame in, as shown in Figure 2 C, or, the operation for the measurement sub-band resources for determining the 6th sub- frame in is not performed, sub-band resources are not measured in the 6th sub- frame in.

Alternatively, in a possible implementation of the present embodiment, in 101, the resource allocation information for downlink data transmission of base station transmission can specifically be received.So, correspondingly, in 102, can also further obtain configured information, the configured information be used to indicating among the sub-band resources indicated by the resource allocation information or outside sub-band resources；Then, then the measurement sub-band resources can be determined according to the resource allocation information and the configured information.

For example, Fig. 2A is the pattern schematic diagram in the corresponding embodiments of Fig. 1 in the sub-band resources indicated by 6 sub- frame in resource allocation informations, it is assumed that configured information indicates the son indicated by the resource allocation information Subband in the subframe corresponding to subband with the sub-band resources among resource indicated by the resource allocation information in even number of subframes, terminal then according to ordering of sub-frames can be followed successively by subband 3, subband 1, subband 2, subband 4, subband 5 and subband 3 according to the subband indicated by the resource allocation information, and the configured information, the sub-band resources that measure are determined for the subband 1 in second sub- frame in, subband 4 and the subband 3 in the 6th sub- frame in the 4th sub- frame in, as shown in Figure 2 D.

Assuming that configured information indicates that subband of the sub-band resources outside the sub-band resources indicated by the resource allocation information indicated by the resource allocation information offsets downward a subband, terminal then according to ordering of sub-frames can be followed successively by subband 3, subband 1, subband 2, subband 4, subband 5 and subband 3 according to the subband indicated by the resource allocation information, and the configured information, determine that the measurement sub-band resources are followed successively by subband 4, subband 2, subband 3, subband 5, subband 6 and subband 4 according to ordering of sub-frames, as shown in Figure 2 E.

Assuming that configured information indicates that the subband in subframe corresponding to subband of the sub-band resources outside the sub-band resources indicated by the resource allocation information indicated by the resource allocation information in even number of subframes offsets downward a subband, terminal then according to ordering of sub-frames can be followed successively by subband 3 according to the subband indicated by the resource allocation information, subband 1, subband 2, subband 4, subband 5 and subband 3, and the configured information, it is the subband 2 in second sub- frame in determine the measurement sub-band resources, in the subband 5 and the subband 4 in the 6th sub- frame in of the 4th sub- frame in, as shown in Figure 2 F.

Alternatively, terminal can also further receive the configured information that the base station is sent.Specifically, terminal can specifically receive the configured information that the base station is sent by high-level signaling.

For example, the high-level signaling can be wireless heterogeneous networks（Radio Resource Control,

RRC) message, can specifically pass through the information element in RRC information（Information Element, IE) configured information is carried, the RRC information can be RRC information of the prior art, for example, RRC connections are reconfigured（RRC CONNECTION RECONFIGURATION) message etc., the present embodiment is to this without limiting, the carrying configured information is extended by the IE to existing RRC information, or the RRC information can also be different from existing RRC information in the prior art.

For another example the high-level signaling can be media access control（Media Access Control, MAC) control element（Control Element, CE) message, specifically it can also carry the configured information by increasing new MAC CE message.

It is understood that the concrete form of the high-level signaling occurred below can similarly carry out the example above, repeat no more later. Alternatively, the configured information can be system be pre-configured with (for example, protocol conventions）, terminal can also further be pre-configured with according to system and obtain the configured information.

Alternatively, in a possible implementation of the present embodiment, in 101, the metrical information for being used to measure of base station transmission can specifically be received.

For example, Fig. 2 B are the pattern schematic diagram in the corresponding embodiments of Fig. 1 in the sub-band resources indicated by 6 sub- frame in metrical informations, terminal can be then the subband 2 in second sub- frame in, subband 3 and the subband 4 in the 6th sub- frame in the 4th sub- frame according to the sub-band resources indicated by the metrical information, so, determine that the measurement sub-band resources are the subband 2 in second sub- frame in, subband 3 and the subband 4 in the 6th sub- frame in the 4th sub- frame in.

Optionally, in 102, it is determined that the measurement sub-band resources at least one subframe periodically can be applied in subsequent subframe, at least one described subframe for it is described measurement sub-band resources cycle.

Alternatively, in a possible implementation of the present embodiment, after 103, terminal further can also report the CSI of molecular band in the middle part of all subbands of CSI or described of all subbands measured in more than one sub- frame in the base station in a sub- frame in where reporting the moment.

It should be noted that described report the moment can be in the way of the cycle or aperiodic mode is determined.Terminal reports the determination mode at moment be obtained by high-level signaling.

For example, described determine to report the moment to be that, by the high-level signaling report cycle certain to terminal configuration and deviant, terminal is calculated by the report cycle and deviant and reports the moment in the way of the cycle.

Alternatively, the report cycle can be more than report cycle of the prior art.

Alternatively, CQI, PMI and RI report cycle and deviant can be respectively configured, and the report cycle and deviant of this three can be with different.

For example, it is described to determine to report the moment to be by Physical Downlink Control Channel (Physical Downlink Control Channel by aperiodic mode, PDCCH the bit triggering carried in) is determined, or the bit triggering carried in accidental access response is determined.If triggering information, (n is the integer more than or equal to 0 n-th）Individual subframe is detected, it is determined that it is that (n is the integer more than 0 to the n-th+k constantly to report）Individual subframe.

Reporting for terminal CSI can have a variety of implementations in the present embodiment, i.e., a variety of to report pattern.Terminal reports the selection of pattern to be obtained by high-level signaling.

It should be noted that the CSI of a subband in the CSI for the subband that the terminal is reported can be measured to the subband in a sub- frame in and obtained, alternatively it is also possible to be in different subframes The average value of the result measured to the subband.

Alternatively, in a possible implementation of the present embodiment, terminal can report all subbands for having been measured in more than one sub- frame in the sub- frame in of where the upper moment to the base station

CSI, as shown in Figure 2 G.The CSI of all subbands measured refers to the CSI measured in the subframe between adjacent two subframes reported where the moment.The moment 1 is reported, the CSI of all subbands measured includes CSI, the CSI of subband 2 of subband 1 and the CSI of subband 3 successively according to the order of subframe;The moment 2 is reported, the CSI of all subbands measured includes CSI, the CSI of subband 5 of subband 4 and the CSI of subband 3 successively according to the order of subframe.Alternatively, the CSI of the subband 3 of two sub- frame in measurements can also be averaged.

It is understood that terminal can also be in a sub- frame in where reporting the moment only to the CSI of the blunt subband measured in a sub- frame on the base station.

Alternatively, in a possible implementation of the present embodiment, terminal is upper, and " a sub- frame in where the moment is reported in all subbands that more than one sub- frame in has been measured to the base station, optimal

(M is the integer more than 0 to M）The CSI of individual subband.Wherein, (M is the integer more than 0 to optimal M）The implication of individual subband refers to, channel quality indicates (Channel Quality Indicator, CQI the channel quality indicated by) is according to the sequence from getting well to going bad, and then for optimal M, (M is the integer more than 0 to the subband corresponding to preceding M CQI）Individual subband, M value can system pre-set or high-level signaling configure.As shown in Figure 2 G, the CSI of all subbands measured refers to the CSI measured in the subframe between adjacent two subframes reported where the moment.The moment 1 is reported, the CSI of all subbands measured includes CSI, the CSI of subband 2 of subband 1 and the CSI of subband 3 successively according to the order of subframe;The moment 2 is reported, the CSI of all subbands measured includes CSI, the CSI of subband 5 of subband 4 and the CSI of subband 3 successively according to the order of subframe.If setting M=2, after comparing, the moment 1 is reported, the CSI of subband 2 optimal in the CSI of all subbands measured and the CSI of subband 3 is reported;The moment 2 is reported, the CSI of subband 4 optimal in the CSI of all subbands measured and the CSI of subband 5 is reported.

It is understood that terminal can also report a sub- frame at moment only to report the CSI of the subband measured in a sub- frame in the base station.

Alternatively, in a possible implementation of the present embodiment, terminal is upper, and " a sub- frame in where the moment reports the CSI measured according to the sub-band sequence indicated by measurement sub-band resources to the base station in turn.As shown in Figure 2 G, the subband indicated by measurement sub-band resources is followed successively by according to the order of subframe Subband 1, subband 2, subband 3, subband 4, subband 5, subband 3, the moment is reported, the CSI of all subbands measured is being reported according to the sub-band sequence indicated by the measurement sub-band resources successively, for example, the moment 1 is reported, the CSI of subband 1 is reported;In the CSI for reporting the moment 2 to report subband 2, by that analogy.

Base station is obtained after the CSI that terminal is reported, the CSI that can be then reported according to the terminal of acquisition, the resource allocation information and/or the metrical information are updated, that is, resource allocation information when updating resource allocation next time and/or metrical information when measuring next time.

For example, it is assumed that system bandwidth has 4 subbands, numbering is 1,2,3 and 4 respectively.In a cycle（Assuming that the cycle includes 4 subframes）, the sub-band resources indicated by resource allocation information are followed successively by subband 1, subband 1, subband 2 and subband 2 according to ordering of sub-frames, and the sub-band resources indicated by metrical information are followed successively by subband 2, subband 2, subband 3 and subband 3 according to ordering of sub-frames.Terminal is according to resource allocation information and metrical information, it is determined that measurement sub-band resources are the subband 2 in first sub- frame in, the subband 2 in second sub- frame in, subband 3 and the subband 3 in the 4th sub- frame in the 3rd sub- frame in.Then, terminal then carries out CSI measurements in the measurement sub-band resources, and ^ in measurement result is blunt to base station.Base station is according to the measurement result, if it find that subband 2 and subband 3 are adapted to this terminal, then in next cycle the sub-band resources indicated by the resource allocation information can be updated to subband 2, subband 2, subband 3 and subband 3 according to ordering of sub-frames successively.But spend a period of time, if the base station find that subband 2 and subband 3 are no longer appropriate for this terminal, it so can then redefine a new metrical information, to indicate new sub-band resources, then, it can then be updated according to measurement result, then by the sub-band resources indicated by the resource allocation information.

In addition, the CSI that base station can also be reported according to the terminal of acquisition, is updated MCS, MIMO relevant configuration.

In the present embodiment, by receiving the resource allocation information for downlink data transmission and/or the metrical information for measurement that base station is sent, and then according to the resource allocation information and/or the metrical information, it is determined that the measurement sub-band resources at least one subframe, make it possible to it is determined that the measurement sub-band resources on, CSI measurements are carried out, can realize that MTC terminal measures CSI.

Alternatively, the CSI can further include order instruction（ Rank Indicator, Rl ) .It should be noted that above-mentioned 301 ~ 302 executive agent can be base station, the terminal being directed to can also be able to be that can support the MTC terminal of a part of bandwidth in system bandwidth for that can support the ordinary terminal of system bandwidth.

It should be noted that system bandwidth can be divided into several sub-band resources.In a sub- frame in, each sub-band resources are to include several resource blocks（Resource Block, RB) resource, the RB numbers that the RB numbers that each sub-band resources indicated by the resource allocation information are included are included with each sub-band resources indicated by the metrical information can be with inconsistent.

It should be noted that the terminal is according to the resource allocation information and/or the metrical information, it is determined that the detailed description of the measurement sub-band resources at least one subframe may refer to the related content in the corresponding embodiments of Fig. 1, here is omitted.

Alternatively, in a possible implementation of the present embodiment, base station further can also send configured information to the terminal, to cause the terminal according to the resource allocation information and the configured information, determine the measurement sub-band resources, the configured information be used to indicating among the sub-band resources indicated by the resource allocation information or outside sub-band resources.The related content that may refer in the corresponding embodiments of Fig. 1 is described in detail, here is omitted.

Specifically, base station specifically to the terminal can send the configured information by high-level signaling.For example, the high-level signaling can be wireless heterogeneous networks（Radio Resource Control, RRC) message, it can specifically pass through the information element in RRC information（Information Element, IE) configured information is carried, the RRC information can be RRC information of the prior art, for example, RRC connections are reconfigured（RRC CONNECTION RECONFIGURATION) message etc., the present embodiment is to this without limiting, the carrying configured information is extended by the IE to existing RRC information, or the RRC information can also be different from existing RRC information in the prior art.

For another example the high-level signaling can be media access control（Media Access Control, MAC) control element（Control Element, CE) message, specifically it can also carry the configured information by increasing new MAC CE message. Alternatively, base station can not also send the configured information to the terminal, the configured information can system be pre-configured with（For example, protocol conventions）, terminal can also further be pre-configured with according to system and obtain the configured information.

Alternatively, in a possible implementation of the present embodiment, after 302, base station can also further receive the CSI of molecular band in the middle part of all subbands of CSI or described for all subbands measured in terminal described in a sub- frame in where reporting the moment in more than one sub- frame in that the terminal is reported.The related content that may refer in the corresponding embodiments of Fig. 1 is described in detail, here is omitted.

Alternatively, in a possible implementation of the present embodiment, base station is obtained after the CSI that terminal is reported, the CSI that can be then reported according to the terminal of acquisition, the resource allocation information and/or the metrical information are updated, that is, resource allocation information when updating resource allocation next time and/or metrical information when measuring next time.

In addition, the CSI that base station can also be reported according to the terminal of acquisition, be updated MCS,

MIMO relevant configuration.

In the present embodiment, by determining the metrical information for the resource allocation information of downlink data transmission and/or for measurement, make it possible to send the resource allocation information and/or the metrical information to terminal, to cause the terminal according to the resource allocation information and/or the metrical information, it is determined that the measurement sub-band resources at least one subframe, it is determined that the measurement sub-band resources on, carry out CSI measurements, can Realize that MTC terminal measures CSI.

Fig. 8 is a kind of flow chart for the method indicated by resource allocation information sub-band resources being related in the corresponding embodiments of Fig. 1 and Fig. 3, as shown in Figure 8.

801st, the information element R of sub-band resources, the frame initial time FRAMESTART of application resource configuration information and subframe initial time SUBFRAMESTART that the cycle T, effective window length 3, instruction of resource allocation information are configured in cycle Τ are determined₀

802nd, the information element R of sub-band resources, the frame initial time FRAMESTART of application resource configuration information and the subframe initial time SUBFRAMESTART configured according to the cycle fourth of the resource allocation information of the determination, effective window length 3, instruction in cycle T, generates resource allocation information.

803rd, the resource allocation information by the generation is notified to terminal.

It should be noted that above-mentioned 801 ~ 803 executive agent can be base station.

In 801, the unit of the cycle T of the resource allocation information can be millisecond, and T is the integer more than or equal to 1.The long S of effective window represents that effective window length is made up of S subframe, and S is the integer more than or equal to 1.The cycle T is comprising " r/ effectively windows are long, and preceding " the effectively long sizes of window of r/-l are S, and last effective long size of window is The long S of effective window represents that each sub-band resources that the resource allocation information is indicated can apply to S subframe.Described information element R can be expressed as a sequence, and the sequence is divided into that " 77 parts, each part is represented with information element N.Described information element N indicates the sub-band resources in a long S of effective window.System bandwidth can be divided into M sub-band resources, in a sub- frame in, and each sub-band resources are the resources for including several RB.N can be integer, alternatively, can also be binary bits, for indicating one or more of M sub-band resources.

Alternatively, in a possible implementation of the present embodiment, the frame initial time and subframe initial time of application resource configuration information can also be determined by formula.For example, the frame initial time and subframe initial time of application resource configuration information can be the numbering or index for meeting SFN and subframeindex in equation below respectively：

(10 X SFN+subframeindex) mod T =Χ;

In above-mentioned formula, SFN (system frame number) is the radio frame number of system, and subframindex is the numbering or index of the subframe in a radio frames, and mod is modulus computing, T is the cycle of resource allocation information, and X is pre-defined constant.

If the frame initial time and subframe initial time of application resource configuration information are determined by formula, In 801, without the frame initial time FRAMESTART and subframe initial time SUBFRAMESTART that determine application resource configuration information₀

In 802, the resource allocation information of the generation can be：

Resourceconfiginfo::=sequence

{ T ENUMERA TED { t1, t2, ....},

S ENUMERATED {s1, s2, ....},

R SEQUENCE (SIZE (ceil(T/S))) of N
