The schematic flow sheet for the channel state information reporting method that Fig. 1 provides for the embodiment of the application one, as shown in Figure 1.
101st, terminal determines at least two CSI for needing to report.
102nd, when the load sum for reporting at least two CSI is more than load threshold value, the terminal is according to the precedence information of at least two CSI, the part CSI at least two CSI is reported, to cause the load sum of the part CSI to be less than or equal to the load threshold value.
It is understood that at least two CSI that the terminal is reported the need for determining can include the CSI in the case of the various hypothesis of terminal measurement.
Alternatively, in a possible implementation of the present embodiment, the CSI is by order instruction（Rank Indicator, Rl), pre-coding matrix instruction (Precoding Matrix Indicator, PMI) and channel quality indicate (Channel Quality Indicator, CQI) composition.
Wherein, the Rl can be that therefore, RI is then full bandwidth RI (or broadband RI) based on system bandwidth measurement；The PMI and CQI can include measuring based on system bandwidth and based on subband measurement, therefore, PMI, which can include full bandwidth PMI (or broadband PMI) or subband PMI, CQI, can include full bandwidth CQI (or broadband CQI) or subband CQI.
Alternatively, in a possible implementation of the present embodiment, in 101, the load at least two CSI that the needs that the terminal is determined are reported can include but is not limited to：
The bit number that at least two CSI is included（ bits ) ；Or
The number of at least two CSI.
Alternatively, in a possible implementation of the present embodiment, before 102, the terminal can also further obtain the load threshold value and the precedence information.
Specifically, the terminal can specifically receive the load threshold value and the precedence information that the base station is sent by high-level signaling.
It should be noted that the terminal can obtain the load threshold value and the precedence information simultaneously, or the load threshold value and the precedence information can also be obtained respectively.
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 the load threshold value and/or the precedence information) are carried, the RRC information can be RRC message of the prior art, for example, RRC connections reconfigure (RRC CONNECTION RECONFIGURATION) message etc., the present embodiment is to this without limiting, the carrying load threshold value and/or the precedence information are 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 can also be new by increase
MAC CE message carries the load threshold value and/or the precedence information.
Specifically, the terminal need not receive the load threshold value and the precedence information that the base station is sent by high-level signaling, but can obtain the load threshold value and/or the precedence information according to being pre-configured with, for example, protocol conventions.
Alternatively, in a possible implementation of the present embodiment, the precedence information can include but is not limited to the first precedence information and/or the second precedence information.Wherein, the content that first precedence information can be according to included by each CSI determines that second precedence information can be according to
The numbering of each CSI, the resource number of each CSI CSI reference signals (CSI RS Reference Signal, CSI-RS) mapping, each CSI interferometry resource（Interference Measurement Resource, IMR) mapping resource number and carry each CSI PUCCH mappings resource number at least one of determine.Wherein, the resource number can include but is not limited to subband numbering, resource block（Resource Block, RB) numbering, portions of bandwidth（Bandwidth Parts, BP) number or subframe number.
For example, the precedence information is first precedence information.First precedence information content included by each CSI can determine that its corresponding mapping ruler can have various ways, e.g., the first highest priority indicated by RI or broadband PMI the first precedence information according to；The first priority indicated by broadband CQI the first precedence information is taken second place；The first priority indicated by subband CQI or subband PMI the first precedence information is minimum.
For example, terminal determines to need to report M that (M is the integer more than or equal to 2）Individual CSI, if reporting the load sum of the M CSI to be more than load threshold value, so terminal then can be according to the first priority indicated by first precedence information, the M CSI reported the need for the determination is ranked up, select N number of CSI that the first priority is higher, due to reporting the load sum of N number of CSI to be less than or equal to load threshold value, therefore, the terminal can then report N number of CSI to base station.
For example, the precedence information is first precedence information and second precedence information.First precedence information content included by each CSI can determine according to, e.g., RI or the first highest priority indicated by corresponding first precedence informations of broadband PMI；The first priority indicated by corresponding first precedence informations of broadband CQI is taken second place；The first priority indicated by corresponding first precedence informations of subband CQI or subband PMI is minimum.Second precedence information can the numbering of each CSI according to, the resource number of each CSI CSI-RS mappings, the resource number of each CSI IMR mappings, the measurement of the resource number and each CSI of each CSI of carrying PUCCH mappings assume at least one of determine, its corresponding mapping ruler can have various ways, such as
Different CSI numbering can determine corresponding second precedence information using same mapping rule, for example, the priority indicated by more big corresponding second precedence information of numbering is bigger.If CSI numbering is identical, then corresponding second precedence information is also identical.
The resource number that different CSI numbering can map according to each CSI CSI-RS, using corresponding mapping ruler, determines corresponding second precedence information.For example, it is assumed that mapping ruler has K (K is more than or equal to 2) to plant, it is F respectively0(), F2(), Fm(), FK-I (), then, when
When resource number divided by K remainder are m, the terminal can then use mapping ruler Fm()。
The resource number that different CSI numbering can map according to the PUCCH for carrying each CSI, using corresponding mapping ruler, determines corresponding second precedence information.For example, it is assumed that mapping ruler has K (K is more than or equal to 2) to plant, it is F respectively.(), F2(), Fm(), FK-I (), then, when the remainder of resource number divided by K is m, the terminal can then use mapping ruler Fm()。
Different CSI numbering can determine corresponding second precedence information according to configured information, using corresponding mapping ruler.For example, it is assumed that mapping ruler has K (K is more than or equal to 2) to plant, it is F respectively0(), F2(), Fm(), FK-1(), then, when the mapping ruler indicated by configured information is FmWhen (), the terminal can then use mapping ruler Fm().Wherein, the configured information can the terminal receive base station and sent by high-level signaling, or can also be the terminal according to being pre-configured with acquisition.
The resource number of different each CSI CSI-RS mappings can determine corresponding second precedence information, for example, the priority indicated by more big corresponding second precedence information of resource number is bigger using same mapping rule.If the resource number of CSI CSI-RS mappings is identical, then corresponding second precedence information is also identical.
The resource number of different each CSI IMR mappings can determine corresponding second precedence information, for example, the priority indicated by more big corresponding second precedence information of resource number is bigger using same mapping rule.If the resource number of CSI IMR mappings is identical, then corresponding second precedence information is also identical.
The resource number of the different each CSI of carrying PUCCH mappings can using same mapping rule shellfish ' corresponding second precedence information is determined, for example, the priority indicated by more big corresponding second precedence information of resource number is bigger.If the resource number for carrying CSI PUCCH mappings is identical, then corresponding second precedence information is also identical.
For example, terminal determines to need to report M that (M is the integer more than or equal to 2）Individual CSI, if reporting the load sum of the M CSI to be more than load threshold value, so terminal then can be according to the first priority indicated by first precedence information, the M CSI reported the need for the determination is ranked up, select N number of CSI that the first priority is higher, due to reporting the load sum of N number of CSI still above load threshold value, therefore, the terminal then can be according to the second priority indicated by second precedence information, N number of CSI of the selection is ranked up, select the P CSI that the second priority is higher, due to reporting the load sum of the P CSI to be less than or equal to load threshold value, therefore, institute
The P CSI can then be reported to base station by stating terminal.
It should be noted that at least two CSI reported the need for terminal is by performing 101 determinations, except other CSI in addition to the 102 part CSI reported are performed, then Ke Yi Jin Hang Lost abandon processing to the terminal.
Alternatively, in a possible implementation of the present embodiment, the part CSI at least two CSI that the terminal can also be reported further according to adjusts the priority indicated by second precedence information.
CSI, reduce the priority indicated by corresponding first precedence information of content included by the part CSI, and/or the numbering of the reduction part CSI, the resource number of the resource number of the CSI-RS mappings of the part CSI, the part CSI IMR mappings and the carrying part CSI PUCCH mappings resource number at least one of priority indicated by corresponding described second precedence information.
The priority indicated by the second precedence information specifically reduced can be determined according to following method：Priority=0 (〇 31 numbering) indicated by second precedence information of reduction, wherein D (CSI numbering) value can be 0 or-A.Wherein A=(max (H (CSI numbering))-min (H (CSI numbering)))+delta, wherein H () is the priority given the correct time on last time CSI indicated by different CSI corresponding second precedence information of numbering, and delta is a positive number.For example, the CSI reported the need for the determination of last time terminal is M, corresponding the D () values of the N number of CSI reported of being given the correct time on last time CSI are-A, and corresponding the D () values of remaining M-N CSI are 0.
CSI, improve the priority indicated by corresponding first precedence information of content included by other CSI at least two CSI in addition to the part CSI, and/or improve in the numbering of other CSI, the resource number for the PUCCH mappings that the resource number of the resource number of the CSI-RS mappings of other CSI, other CSI IMR mappings and ^^ carry other CSI at least one of priority indicated by corresponding described second precedence information.The priority indicated by the second precedence information specifically improved can be determined according to following method：
Priority=the D (CSI numbering) indicated by the second precedence information improved, wherein D (CSI numbering) value can be 0 or A.Wherein A=(max (H (CSI numbering))-min (H (CSI numbering)))+delta, wherein H () is the priority given the correct time on last time CSI indicated by different CSI corresponding second precedence information of numbering, and delta is a positive number.For example, reported the need for the determination of last time terminal
CSI is M, and corresponding the D () values of the N number of CSI reported of being given the correct time on last time CSI are 0, and corresponding the D () values of remaining M-N CSI are A.
In the present embodiment, at least two CSI for needing to report are determined by terminal, so that when the load sum for reporting at least two CSI is more than load threshold value, the terminal can be according to the precedence information of at least two CSI, report the part CSI at least two CSI, to cause the load sum of the part CSI to be less than or equal to the load threshold value, can be when terminal needs to report the CSI for each transmission point, the problem of appropriate Slow solutions can not report the CSI for all transfer points for being the terminal common service for some reason.

It should be noted that receiver 31 can obtain the load threshold value and the precedence information simultaneously, or the load threshold value and the precedence information can also be obtained respectively.
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 the load threshold value and/or the precedence information) are carried, the RRC information can be RRC message of the prior art, for example, RRC connections reconfigure (RRC CONNECTION RECONFIGURATION) message etc., the present embodiment is to this without limiting, the carrying load threshold value and/or the precedence information are 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 load threshold value and/or the precedence information by increasing new MAC CE message.
Specifically, the terminal need not receive the load threshold value and the precedence information that the base station is sent by high-level signaling, but can obtain the load threshold value and/or the precedence information according to being pre-configured with, for example, protocol conventions.
Alternatively, in a possible implementation of the present embodiment, the precedence information can include but is not limited to the first precedence information and/or the second precedence information.Wherein, first precedence information content included by each CSI can determine according to, second precedence information can the numbering of each CSI according to, the resource number of the resource number of each CSI CSI-RS mappings, each CSI IMR mappings and each CSI of carrying PUCCH mappings resource number at least one of determination.Wherein, the resource number can include but is not limited to subband numbering, resource block（Resource Block, RB) numbering, portions of bandwidth（Bandwidth Parts, BP) number or subframe number.
For example, the precedence information is first precedence information.First precedence information content included by each CSI can determine that its corresponding mapping ruler can have various ways, e.g., the first highest priority indicated by RI or broadband PMI the first precedence information according to；The first priority indicated by broadband CQI the first precedence information is taken second place；The first priority indicated by subband CQI or subband PMI the first precedence information is minimum.
For example, processor 21 determines to need to report M that (M is the integer more than or equal to 2）Individual CSI, if reporting the load sum of the M CSI to be more than load threshold value, then processor 21 is then
Can be according to the first priority indicated by first precedence information, the M CSI reported the need for the determination is ranked up, select N number of CSI that the first priority is higher, due to reporting the load sum of N number of CSI to be less than or equal to load threshold value, therefore, transmitter 22 can then report N number of CSI to base station.
For example, the precedence information is first precedence information and second precedence information.First precedence information content included by each CSI can determine according to, e.g., RI or the first highest priority indicated by corresponding first precedence informations of broadband PMI；The first priority indicated by corresponding first precedence informations of broadband CQI is taken second place；The first priority indicated by corresponding first precedence informations of subband CQI or subband PMI is minimum.Second precedence information can be in the numbering of each CSI according to, the resource number of each CSI CSI-RS mappings, the resource number of the resource number of each CSI IMR mappings and each CSI of carrying PUCCH mappings at least one of determine, its corresponding mapping ruler can have various ways, such as
