Specific embodiment

With reference to the accompanying drawing, embodiments herein is described.

Fig. 1 gives the corresponding communication process of the application.Firstly, the network equipment sends reference signal, for example, channel status Reference signal (channel state information reference signal, CSI-RS) is to terminal device.Terminal is set It is standby to carry out channel estimation, PMI is calculated according to channel estimation results, channel quality is calculated according to PMI and indicates (channel Quality indicator, CQI), according to PMI and CQI selection order instruction (rank indicator, RI), by order instruction RI, The channel state informations such as Ρ Μ Ι, CQI are at uplink control channel (physical uplink control channel, PUCCH) On feed back to the network equipment.The network equipment determines pre-coding matrix based on the RI and PMI received, determines that modulation is compiled according to CQI Code hierarchical modulation coding mode (modulation and coding scheme, MCS).The network equipment uses pre-coding matrix pair The data transmitted on DSCH Downlink Shared Channel (physical downlink shared channel, PDSCH) carry out precoding, The data after precoding are sent according to MCS.

By the feedback of the above channel state information (channel state information, CSI), including RI, PMI, CQI etc., 5G mobile communication system can make transmission adapt to current channel conditions and therefore realize great performance gain.Its In, CSI can be the combined form of time domain channel information, frequency domain channel information or both.Time domain channel information can be short-term channel The form of information or long-term channel information, and frequency domain channel information can be sub-band channel information or the form of broadband channel information.

Wherein, broadband channel information, which refers to, distributes to the whole bandwidth of terminal device as a channel square in the network equipment Battle array carries out channel estimation and obtains channel state information.Sub-band channel information, which refers to, distributes to the whole of terminal device for the network equipment It is divided into multiple subbands in a bandwidth, carries out channel estimation respectively as a channel matrix on each subband, and obtain each Channel state information on subband.Short-term channel information refer to multiple periods that a period of time divides it is upper each (several milliseconds~ A few tens of milliseconds) carry out the channel state information that channel estimation obtains.Long-term channel information refers to that this is used as one for a period of time Whole (a few tens of milliseconds~several hundred milliseconds) carries out the channel state information that channel estimation obtains.Therefore, broad-band channel status information It may include broadband RI, broadband PMI, broadband CQI, phase factor between the panel of broadband, sub-band channel status information can wrap enclosed tool Band RI, subband PMI, subband CQI, phase factor between subband panel.Long-term channel status information includes long-term RI, long-term PMI, length Phase CQI.Short-term channel status information includes short-term RI, short-term PMI, short-term CQI.For in long-term or broad-band channel status information Each is usually a kind of value, and each in subband or short-term channel status information is usually a variety of values.

For RI, PMI, CQI etc. would generally on PUCCH periodic feedback and on PUSCH aperiodicity feed back, Generally it can be defined and be configured by high-level signaling in 3GPP agreement.In addition, whole system bandwidth is divided into multiple subbands.RI is logical It is often determined, i.e., is calculated based on system bandwidth by being assumed the transmission in system bandwidth, and by system The CQI and PMI that transmission in bandwidth is assumed to calculate are known as broadband CQI and broadband PMI, by the transmission on subband The CQI and PMI for being assumed to calculate are known as subband CQI and subband PMI.

Transferring content in PUCCH can have multiple format.The resource as possessed by PUCCH may limited, PUCCH The bit number that can be accommodated in format is also limited.The bit number that every kind of format can accommodate, also known as CSI magnitude of load (CSI Payload size) it is usually predetermined, therefore the RI/PMI/CQI etc. that CSI includes can be split and be passed in multiple times Defeated unit (for example, subframe, time slot, mini time slot etc.).It should be noted that RI/PMI/CQI according to different feedback cycles, Different frequency domain feedback granularities (such as subcarrier spacing) are classified, and are reported in multiple subframes.For example, RI can picture Long-term channel information is fed back like that with the relatively long period, and broadband PMI and/or broadband CQI and subband PMI and/ Or subband CQI can be fed back with the relatively short period.Terminal device can based on the CSI content reported in previous subframe come The CSI content reported in calculated for subsequent subframe.

Specifically, for example, terminal device exists in long term evolution (long term evolution, LTE) communication system The upper periodic feedback CSI of PUCCH includes following several modes:

Wherein, the period of change of RI, the first PMI of broadband are longer, the period of change of the 2nd PMI of broadband CQI and broadband compared with It is short, therefore the period of required subframe is different, the subframe of subframe type 1, the subframe of subframe type 2 belong to period longer son here Frame；The subframe of the subframe of subframe type 3 belongs to period shorter subframe.X, Y is all larger than 1 integer.

1) PUCCH mode (mode) 1-1: RI, PMI and CQI are fed back respectively in the subframe of three types:

Information is reported in the subframe of subframe type 1: RI

Information is reported in the subframe of subframe type 2: the first PMI of broadband

Information is reported in the subframe of subframe type 3: the 2nd PMI of broadband CQI and broadband

In another example UCI's reports to be configured with CSI in configuration and report and reports with RSRP.The UCI is reported, is configured on this PUCCH resource used in reporting, that is, CSI and RSRP uses the PUCCH resource.In another example UCI's reports in configuration It is configured with CSI to report, reporting for another UCI is configured with RSRP and reports in configuration, then configures the UCI configuration information that CSI is reported In may include the report cycle of CSI and/or the resource distribution of sub-frame offset and PUCCH resource or PUCCH resource rope Draw.It may include the report cycle and/or sub-frame offset and PUCCH money of RSRP in the UCI configuration information that reports of configuration RSRP The resource index in source or the resource distribution of PUCCH resource.

As an optional embodiment, terminal device is according to the configuration information of multiple UCI and matching for multiple PUCCH resources Confidence, which ceases, determines that the corresponding relationship of multiple UCI and multiple PUCCH resources can be determined using following methods:

Method 1: reporting the index of set according to CSI, or, the resource index of channel measurement resource, or, the rope of measuring assembly Draw, or, the index of channel connection indexed to determine multiple UCI, uses multiple PUCCH further according to the indexed sequential of multiple UCI Resource.

Wherein, the index of set is reported according to CSI, or, the resource index of channel measurement resource, or, the rope of measuring assembly Draw, or, channel connection index in any index, determine the index of multiple UCI, for example, CSI report set index include 1, 2,3 (reporting setting1, reporting setting 2, reporting setting 3), then it is corresponding multiple UCI includes UCI1, UCI2, UCI3.

Specifically, it is that CSI reports the index of configuration (CSI reporting setting) to believe that CSI, which reports the index of set, Breath.CSI, which reports to may include in configuration information, reports CSI parameter (reported CSI parameter (s)), CSI type (CSI type), codebook configuration (codebook configuration) information, time domain behavior (time-domain Behavior), at least one in the frequency domain granularity (frequency granularity) of CQI and PMI.User equipment according to CSI reports the index of configuration to determine that CSI reports configuration, and reports configuration to carry out the measurement of CSI and report according to the CSI.

The resource index of channel measurement resource is the index information that resource is measured for measuring the CSI of channel.For measuring The CSI measurement resource of channel can be contained in CSI measurement resource distribution (CSI resource setting) set.According to The index that CSI for measuring channel measures resource determines the index of UCI, and the resource index difference of multiple channel measurement resources is true The index of multiple UCI is determined.It includes for channel that wherein CSI, which measures resource distribution (CSI resource setting) set, The CSI of measurement measures resource, at least one of CSI measurement resource of interference measurement.

The index of channel connection is the index information for the connection that attribute is channel measurement.Specifically, connection (Link) is matched The instruction including CSI measurement resource distribution set is set, CSI reports the instruction of configuration set, measures attribute (channel measurement or interference Measurement) instruction.Connection illustrates that CSI measurement resource distribution set and CSI report the connection relationship of configuration set.

The index of measuring assembly is the index of measuring assembly (measurement setting).Wherein, measuring assembly is to survey Amount resource distribution and the set for reporting the relationship between configuration set, it may include one or more connection (Link), a terminal A measuring assembly can only be configured.

Pair (UCI that index is 1) and UCI2 are reported using PUCCH resource 1 and PUCCH resource 2 respectively for example, UCI1, i.e., The UCI of any of the above-described index is answered to be mapped in the PUCCH resource of same index, i.e. UCI1 uses PUCCH resource 1, and UCI2 is used PUCCH resource 2.

Method 2: according to the configuration of QCL or control channel, the one-to-one relationship of UCI and PUCCH resource is determined

Specifically, predefined or signal deployment QCL and PUCCH resource correspond, predefined or signal deployment QCL It is corresponded with UCI, the signaling is high-level signaling or physical layer signaling.For example, the corresponding UCI1 of QCL1 is corresponding using QCL1 PUCCH resource 1 reports.The corresponding UCI2 of QCL2 corresponds to PUCCH resource 2 using QCL2 and reports.User equipment is in corresponding PUCCH UCI is mapped in resource and is reported.

QCL is quasi- co-located information, and definition can be with reference to the definition in LTE, i.e., the letter sent out from the antenna port of QCL Number it can pass through identical large-scale fading, large-scale fading includes following one or more: delay spread, doppler spread, more General Le frequency displacement, average channel gain and average delay etc..The definition of QCL can also be with reference to QCL in 5G in the embodiment of the present application Definition, it is similar with LTE system to the definition of QCL in new wireless NR system, but spatial information (si) is increased, such as: from the day of QCL The signal that line end mouth is sent out can pass through identical large-scale fading, wherein large-scale fading includes one in following parameter It is or multinomial: delay spread, doppler spread, Doppler frequency shift, average channel gain, average delay and airspace parameter etc., airspace Parameter then can be for such as the angle of departure (AOA), the main angle of departure (Dominant AoA), average angle of arrival (Average AoA), arrival Angle (AOD), channel correlation matrix, the power perspective spread spectrum of angle of arrival, average Trigger Angle (Average AoD), the angle of departure Power perspective spread spectrum, launch channel correlation receive channel relevancy, launching beam molding, receive beam forming, space letter Road correlation, filter, space filtering parameter, or, space receives one in parameter etc..QCL relationship includes meeting QCL relationship Channel state information reference signals (channel state information-reference signal, CSI-RS), DMRS, Phase Tracking reference signal (phase tracking reference signal, PTRS) (alternatively referred to as phase compensation Reference signal (phase compensation reference signal, PCRS), or, phase noise reference signal (abbreviation phase Make an uproar reference signal)), synchronization blocks (SS block) (including one or more of synchronization signal and broadcast channel, synchronization signal packet Include primary synchronization signal PSS and/or the one or more from synchronization signal SSS).

In the method, the measurement of UCI is based on QCL information, and the configuration information of QCL can determine the index of UCI, such as The index of UCI is determined by the index of QCL.For example, UCI1 is according to CSI measurement resource (such as channel measurement for being configured with QCL#1 Resource) measured by, UCI2 is measured measured by resource (such as channel measurement resource) according to the CSI for being configured with QCL#2.

Method 3: according to control resource distribution (control resource set, CORESET)/control channel element (control channel element, CCE)/control channel search alternative (candidates) used determines that PUCCH is provided Source, for example, the corresponding UCI1 of CORESET 1 is reported in the corresponding PUCCH resource 1 of CORESET 1.CORESET 2 is corresponding UCI2 is reported in the corresponding PUCCH resource 2 of ORESET 2.User equipment maps UCI and is reported in corresponding PUCCH resource.

Control resource distribution (CORESET) is the configuration information for controlling information, e.g., CORESET configuration.Control resource distribution It may include the frequency domain resource for controlling information, starting OFDM symbol, temporal duration, REG combined size (REG bundling Size), at least one of transport-type (whether interweaving) etc..

Control channel element (CCE) is the resource units of control channel, is made of C REG, wherein C be 9 or 4 or other Positive integer.

Control channel search alternative (candidate) is that the search space of control information is alternative.

In the method, PUCCH resource index can the CORESET corresponding to the PUCCH resource configuration index Lai It determines, is perhaps determined by the index of CCE or determined by candidate index.

Moreover, it will be understood that if the number of PUCCH resource is identical with the number of UCI, it can be according to the index of the two Determine one-to-one relationship, for example, reporting in configuration for UCI is to have reported 2 UCI, however PUCCH resource is configured with 2, UCI1 then is mapped in first PUCCH resource, maps UCI2 in second PUCCH resource.At this point, if two PUCCH moneys The index in source is respectively PUCCH resource 1 and PUCCH resource 2, and the index of two UCI is respectively UCI1 and UCI2, then in PUCCH UCI1 is mapped in resource 1, maps UCI2 in PUCCH resource 2；If the index of two PUCCH resources is respectively PUCCH resource 8 With PUCCH resource 9, the index of two UCI is respectively UCI3 and UCI4, then maps UCI3 in PUCCH resource 8, is provided in PUCCH UCI4 is mapped on source 9, it is therefore, identical to stringent the two index can be not limited to when corresponding to as UCI in PUCCH resource, only need It is corresponded according to the sequence respectively indexed, i.e., first PUCCH resource in PUCCH resource index corresponds to UCI index In first UCI.

If the number of PUCCH resource and the number of UCI be not identical, it is subject to lesser number.For example, UCI's is upper It is to have reported 2 UCI, however PUCCH resource is configured with 3 in report configuration, then maps UCI1 in first PUCCH resource, UCI2 is mapped in second PUCCH resource, does not use third PUCCH resource.

For example, reporting in configuration for UCI is to have reported 3 UCI, however PUCCH resource is configured with 2, then on PUCCH11 UCI1 is mapped, maps UCI2 on PUCCH2, UCI3 is not reported.

Therefore, in this application, predefined or signal deployment multiple UCI and multiple PUCCH resources corresponding relationship.? UCI is reported in configuration, configures PUCCH resource, or the index of configuration PUCCH resource.Signal deployment PUCCH resource or resource group Index.The configuration of PUCCH resource group saves signaling overheads.The one-to-one relationship of multiple UCI and multiple PUCCH resources mentions High PUCCH resource utilization rate.
