Description

Reporting status information of channel, the method for determining modulation coding mode and device

Technical field

The present invention relates to communication technical field, relate in particular to a kind of reporting status information of channel, determine method and the device of modulation coding mode.

Background technology

At LTE-A(Long Term Evolution-Advanced, senior Long Term Evolution) in the downlink transmission of system, for auxiliary eNB(eNodeB, base station) select suitable MCS(Modulation and Coding Scheme, modulation coding mode), UE(User Equipment, subscriber equipment) need to feed back some channel condition informations (Channel State Information to eNB, CSI), in CSI, can comprise CQI(Channel Quality Indicator, channel quality indication), PMI(Precoding Matrix Indicator, pre-coding matrix indication), PTI(Precoding Type Indication, precoding type is indicated) and RI(Rank Indicator, order indication) etc.ENB determines according to up (UL) feedback information receiving the MCS that descending (DL) subframe is used, and realizes Adaptive Modulation and Coding (Adaptive Modulation and Coding, AMC).

LTE-A and LTE all support FDD(Frequency Division Duplex, Frequency Division Duplexing (FDD)) and TDD(Time Division Duplex, time division duplex) two kinds of duplex modes.In the TDD of LTE-A duplex mode, sending and receiving signal is in identical frequency band, up-downgoing radio frames, by sending and distinguish in the time periods different on time shaft, can comprise in a radio frames: descending sub frame, sub-frame of uplink, special subframe and flexible sub-frame.Wherein, flexible sub-frame is the LTE-A subframe type newly-increased compared with LTE, and this flexible sub-frame can be dynamic or semi-static is configured to descending sub frame or sub-frame of uplink.

In prior art, UE reports time point only to report the up-to-date CSI that the last time measures, and no matter this subframe is fixedly subframe or flexible sub-frame, the CSI that base station measured according to UE the last time of reporting determines the MCS that current subframe scheduling is used, also no matter current subframe is fixedly subframe or flexible sub-frame.Thereby there is such problem: if the up-to-date CSI that measures of UE the last time comes from fixedly subframe, measure, and the selection reference of the MCS of flexible sub-frame may be used it in base station, or, if the up-to-date CSI that UE the last time measures comes from flexible sub-frame and measures, and the fixedly selection reference of the MCS of subframe may be used it in base station, at this moment, because fixedly the CSI in subframe and CSI in flexible sub-frame have larger difference because the interference of neighbor cell is around different, if according to determine the MCS of flexible sub-frame from the fixing CSI of subframe, or determine the fixedly MCS of subframe according to the CSI from flexible sub-frame, just there will be larger error, cause the MCS determining not accurate enough, affect efficiency of transmission.

Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.

As shown in Figure 1, the method flow diagram of a kind of reporting status information of channel providing for the embodiment of the present invention, is described below.

Step 101: subscriber equipment is determined at least one channel condition information, described at least one channel condition information is the channel condition information of at least one subframe or at least one subframe collection.

In LTE-A system, reporting of channel condition information can comprise that aperiodicity reports and periodically report two kinds.

It can be by network equipment that aperiodicity reports, for example base station triggers is used PUSCH(Physical Uplink Shared Channel, Physical Uplink Shared Channel) resource reporting, periodically report mainly (Physical Uplink Control Channel on PUCCH, Physical Uplink Control Channel) feedback, it is to supplementing of periodically reporting that trigger-type aperiodicity reports.

Periodicity on PUCCH reports and mainly can be divided into broadband and report pattern (Mode1-0/1-1) and frequently choose two types of report patterns (Mode2-0/2-1).Broadband reports pattern only to feed back broad-band channel state information, frequently chooses the feedback of existing broad-band channel state information of report pattern, also has the feedback of sub-band channel state information.As shown in Figure 2 A and 2 B, wherein, Fig. 2 A represents that broadband reports pattern, and Fig. 2 B represents frequently to choose report pattern.WB in Fig. 2 A and Fig. 2 B represents broadband, and the SB in Fig. 2 B represents subband, and the Np in Fig. 2 A represents report cycle.

Aperiodicity reports and can be called trigger-type and reports, trigger-type reports and mainly passes through network equipment, for example base station is at descending PDCCH(Physical Downlink Control Channel, Physical Downlink Control Channel) in channel, send UL grant (uplink scheduling signaling) to subscriber equipment (UE), wherein can include " CSI request " field(channel condition information request domain) field triggers UE reporting status information of channel when this field is effective.PDCCH channel can be divided into two search volumes, is respectively public search space (CSS) and UE dedicated search space (USS).CSS is for sending the common control information of all UE, and USS is for sending the control information of particular UE.

In LTE system, support two kinds of frame structures---Frequency Division Duplexing (FDD) (FDD) and time division duplex (TDD).In tdd frame structure, the radio frames of 10ms is divided into the field that two length are 5ms, and each field is long for the subframe of 1ms forms by 5, comprising 4 common subframes and 1 special subframe.Common subframe is comprised of two 0.5ms; and special subframe is comprised of 3 special time slots; these 3 special time slots are respectively UpPTS(Uplink Pilot TimeSlot; uplink pilot time slot), GP(Guard Period; protect interval) and DwPTS(Downlink Pilot TimeSlot, descending pilot frequency time slot), wherein DwPTS is for the transmission of downstream signal; UpPTS is for the transmission of upward signal, and GP is the protection interval of TDD up-downgoing conversion.

As a feature of TDD system, time resource distributes on up-downlink direction.Tdd frame structure supports 7 kinds of different up-downgoing time scales to distribute (configuring 0～6) at present.Can be configured according to the characteristic of traffic carrying capacity.These 7 kinds of configurations comprise the situation in 4 kinds of 5ms cycles and 3 kinds of 10ms cycles.In the configuration in 5ms cycle, the conversion interval that every 5ms comprises a downstream-to-upstream, and in the configuration of the cycle of 10ms, the conversion interval that every 10ms comprises a downstream-to-upstream.Concrete configuration is as shown in table 1, and wherein " D " represents descending sub frame, and " U " is expressed as sub-frame of uplink, and " S " is expressed as the special subframe that comprises conversion interval.

Table 1

LTE is discussing TDD up-downgoing flexible sub-frame allocation problem at present.The method of this configuration is that UE can be used above-named different TDD proportioning within the shorter cycle.

What for example in first 400ms, UE adopted is up-downgoing proportioning 0, at next 400ms, just can adopt up-downgoing proportioning 1.Such benefit is just can adopt the configuration of many sub-frame of uplink such as proportioning 0 when uplink service system of many times, just can adopt the many configurations of descending sub frame configuration, such as proportioning 2 when downlink business is many.Generally, can do sub-frame of uplink and can do again the subframe of descending sub frame and be called flexible sub-frame, for example, if system configuration UE can change between up-downgoing proportioning 0 and up-downgoing proportioning 2, flexible sub-frame can be just subframe 3,4,8,9 so.Interference and the UE interference difference in flexibly upper and lower subframe of UE in fixing sub-frame of uplink is larger.

Preferably, in the embodiment of the present invention, described subscriber equipment is determined described at least one channel condition information, can be specifically: described subscriber equipment is determined on the first descending sub frame or the channel condition information measuring on the descending sub frame of the first descending sub frame collection, and determine at least one the second descending sub frame or the channel condition information measuring on the descending sub frame of the second descending sub frame collection.

Wherein, described the first descending sub frame is fixing subframe, described the first descending sub frame collection is the subframe collection that fixedly subframe forms, can be called fixedly subframe collection, described the second descending sub frame is flexible sub-frame, described the second descending sub frame integrates the subframe collection forming as flexible sub-frame, can be called flexible sub-frame collection.

That is,, in the embodiment of the present invention, UE can only determine a channel condition information measuring in fixing subframe, and a definite channel condition information measuring in flexible sub-frame.

For example, UE can determine 2 channel condition informations.Channel condition information channel condition information for measuring in fixing subframe, fixedly subframe can be for example No. #0 shown in table 1, No. #5, No. #1 or #6 work song frame, channel condition information channel condition information for measuring in flexible sub-frame, flexible sub-frame can be for example that the #3 shown in table 1, #4, #7(are undetermined), #8 or #9 work song frame.

But preferably, flexible sub-frame may be divided into because disturbing difference a plurality of flexible sub-frame collection, UE is when determining the channel condition information measuring in flexible sub-frame, can determine a channel condition information according to each flexible sub-frame collection, determine a plurality of channel condition informations that measure in flexible sub-frame, these a plurality of flexible sub-frame belong to respectively different flexible sub-frame collection.

Like this, described subscriber equipment can be determined the channel condition information measuring in fixing subframe simultaneously, and the channel condition information measuring in flexible sub-frame, described subscriber equipment can all report network equipment by these channel condition informations, described network equipment can therefrom select own required channel condition information to apply, can make the modulation coding mode determined according to channel condition information comparatively accurate, or the channel condition information that described subscriber equipment can directly need described network equipment reports, both saved and reported required expense, also can reach the demand of described network equipment, can make the modulation coding mode determined according to channel condition information comparatively accurate.

Step 102: described subscriber equipment reports the part or all of channel condition information in definite described at least one channel condition information to network equipment.

Described subscriber equipment, after determining described at least one channel condition information, can report impaction of partial channel state information or whole channel condition information wherein to described network equipment.

Optionally, in one embodiment of the invention, described subscriber equipment reports the part or all of channel condition information in definite described at least one channel condition information to network equipment, can be specifically: described subscriber equipment all reports whole channel condition informations of determining.

For example, described subscriber equipment may have been determined a channel condition information fixedly measuring in subframe, and a plurality of channel condition information measuring in flexible sub-frame, and described subscriber equipment can all report these channel condition informations.

Upper, give the correct time, particularly, for periodically reporting, owing to having reported a plurality of channel condition informations, may cause PUCCH expense double, may occur exceeding the original original bearer cap of some transformat.For example, the form 3 of the form 2b/ control signal of the form 2a/ control signal of form 2/ control signal of Format2/2a/2b/3(control signal) channel condition information giving the correct time on may be used to transmit periodically, but the information bit restriction that the form of every kind of control signal has maximum to transmit.For example Format2 maximum can be transmitted 11 bits, Format2a maximum can be transmitted 12 bits (wherein also needing to transmit 1 bit A/N(acknowledgement/non-acknowledgement), space for transmitting channel state information also only has 11 bits), Format2b maximum can be transmitted 13 bits (wherein needs to pass 2 bit A/N, space for transmitting channel state information also only has 11 bits), Format3 maximum under FDD can be transmitted 11 bits, and under TDD, maximum can be transmitted 21 bits.Visible, for the form of a control signal, not necessarily can meet the transmission demand in the embodiment of the present invention.

Preferably, in the embodiment of the present invention, described subscriber equipment reports the part or all of channel condition information in definite described at least one channel condition information to network equipment, can be specifically: the first transfer resource that described subscriber equipment configures by described network equipment, the channel condition information that transmission measures on fixing descending sub frame, and the second transfer resource configuring by described network equipment, the channel condition information that transmission measures on described at least one flexible descending sub frame.

For example, described subscriber equipment can transmit the channel condition information measuring on fixing descending sub frame by Format2a, and can transmit the channel condition information measuring on described at least one flexible descending sub frame by Format2b.Like this, different channel condition informations adopts different resources to transmit, and can meet the demand of a plurality of channel condition informations of transmission.
