Description

Information reporting method and equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and a device for reporting information.

Background

The PDCSH (downlink physical shared channel) of LTE (Long Term Evolution) supports three coding modes, which are: QPSK (Quadrature) Phase Shift Keying), 16QAM (Quadrature Amplitude Modulation) and 64QAM, the three coding schemes require different channel conditions, the higher the coding scheme is, the better the channel condition is.

As will be understood by those skilled in the art, downlink scheduling is determined by a base station, and the base station as a transmitting end does not know how the channel condition is, so a UE (User Equipment) is required to measure the channel quality and feed back to the base station. When measuring the Channel Quality, the UE quantizes the Channel Quality to a sequence of 0 to 15 and defines the sequence as a Channel Quality Indicator (CQI), that is, the UE feeds back Channel Quality Information (CQI) to the base station periodically (i.e., periodically) or aperiodically (aperiodically), and the base station determines the coding mode according to the CQI reported by the UE.

Currently, a link for Uplink transmission in the LTE system includes a PUCCH (Physical Uplink Control CHannel) and a PUCSH (Physical Uplink Shared CHannel), where the PUCCH is used for transmitting Control signaling and the PUCSH is mainly used for transmitting data.

The UE reports a periodic CQI through a PUCCH, and meanwhile, the UE may also report a PMI (Pre-coding Matrix Indicator) and an RI (Rank Indicator) through the PUCCH to the base station, where the CQI, the PMI, and the RI are collectively referred to as CSI (Channel State Information). Therefore, CSI may also be divided into periodic CSI and aperiodic CSI.

The conventional terminal reports periodic CSI through a PUCCH and reports aperiodic CSI through a PUSCH. The relation between PUCCH and PUSCH in time domain and frequency domain is shown in fig. 1. When the aperiodic CSI is reported, the UE inserts the aperiodic CSI into uplink data carried by a PUSCH and reports the uplink data together under a normal condition, and if no data to be reported through the PUSCH exists when the aperiodic CSI is required to be reported, the aperiodic CSI is reported separately through the PUSCH.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Some of the words referred to in the examples of the present application are explained below:

1. the term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

2. In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

3. The term "terminal" in the embodiments of the present application refers to a terminal capable of supporting radio frequency communication, that is, a mobile phone, a tablet, and the like.

The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it should be understood that the preferred embodiments described herein are merely for illustrating and explaining the present application, and are not intended to limit the present application, and that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Conventionally, the PUCCH mainly carries periodic CSI, SR, and HARQ ACK/NACK (hereinafter abbreviated ACK/NACK), which are collectively referred to as UCI. The SR is a scheduling request sent by the UE to the base station, the ACK/NACK is feedback of the UE on the PDSCH, that is, the base station is notified whether data issued by the PDSCH is correct, and if the feedback is NACK, the base station retransmits the corresponding data to the UE.

And the terminal detects that UCI reporting requirements exist, modulates signals contained in the UCI and reports the signals through at least one PUCCH subframe.

The embodiment of the invention provides a new reporting mode, which is applied to a terminal to report periodic CSI and aperiodic CSI to a base station through a PUCCH. The base station may be a device with a wireless communication function, such as: macro base station, micro base station. As shown in fig. 2, it is a schematic view of an application scenario in which a terminal reports periodic CSI and aperiodic CSI.

After detecting that UCI reporting requirements exist, the terminal modulates signals contained in the UCI and reports the signals through at least one PUCCH subframe, or after detecting that aperiodic CSI reporting requirements exist, modulates signals contained in the aperiodic CSI and reports the signals through at least one PUCCH subframe.

In the reporting scenario provided by the present application, one possible situation is that the terminal has the reporting requirements of the aperiodic CSI and the periodic CSI at the same PUCCH subframe, that is, a reporting collision occurs, which may also be understood as a reporting collision, as shown in the scenario diagram shown in fig. 3.

Therefore, the present application provides a new reporting mode, in which the terminal reports the aperiodic CSI through the PUCCH to avoid resource waste caused when the aperiodic CSI is reported through the PUSCH alone, and further, the present application further includes a selection strategy when the aperiodic CSI and the UCI are reported through the PUCCH to generate a reporting conflict, so that when the aperiodic CSI and the UCI generate a reporting conflict, the terminal selects information to be reported through the selection strategy of the present application to minimize the influence on transmission of the system.

As shown in fig. 4, an embodiment of the present invention provides a method for reporting information, which specifically includes the following steps:

step S400: after a terminal determines that reporting requirements of aperiodic Channel State Information (CSI) and Uplink Control Information (UCI) exist in the same PUCCH subframe, the remaining space capacity after the non-periodic CSI is carried by the PUCCH subframe is determined;

step S401: the terminal selects part or all information from the UCI according to the space capacity;

step S402: and the terminal reports the selected information and the aperiodic CSI through the PUCCH subframe.

By the scheme, the terminal detects that the aperiodic CSI and the UCI need to be reported at the same PUCCH subframe, namely the aperiodic CSI and the UCI are reported and collided. And the terminal determines the residual space capacity after the non-periodic CSI is carried by the PUCCH subframe, selects part or all information with the capacity not larger than the residual space capacity from the UCI, places the selected information in the PUCCH subframe carrying the non-periodic CSI and reports the information together. The embodiment of the application provides a new aperiodic CSI reporting scheme, and further comprises a selection strategy when the aperiodic CSI reported by a terminal through a PUCCH conflicts with UCI, so that the normal reporting of the aperiodic CSI is ensured, and the influence on the transmission of UCI information is reduced.

Because the aperiodic CSI has aperiodic nature, if the aperiodic CSI and the UCI generate reporting conflict at the PUCCH subframe, if the aperiodic CSI is discarded, compared with discarding the periodic UCI, the base station may need to wait for a longer period to receive the aperiodic CSI again, therefore, in the embodiment of the present invention, when the terminal transmits the aperiodic CSI through the PUCCH, if the aperiodic CSI and the UCI generate reporting conflict, the aperiodic CSI is selected to be reported, and if the aperiodic CSI is modulated, the PUCCH subframe still has vacant symbols (i.e., remaining spatial capacity), part or all of the information is selected from the UCI and reported together through the PUCCH subframe.

The following illustrates a manner of determining the remaining spatial capacity of the PUCCH subframe:

description is first made on PUCCH:

taking an LTE system as an example, a length of one radio frame is 10ms, one radio frame includes 10 subframes, as shown in fig. 5, a structural diagram of a PUCCH subframe when a subcarrier interval is 15KHz (normal CP), a PUCCH subframe length is 1ms, and includes 1 slot, and the number of OFDM symbols included in each slot is 14.

When the terminal reports UCI and/or aperiodic CSI through a PUCCH, PUCCH channel control information, namely PUCCH-specific reference signals (DMRS), is also transmitted along with the UCI and/or aperiodic CSI information, wherein the DMRS is used for the base station to demodulate PUCCH signals.

Existing PUCCH formats include 1/1a/1b/2/2a/2b, and DMRSs carried by different PUCCH formats are also different, for example, as shown in fig. 6, a PUCCH format 1/1a/1b, where DMRSs occupy the 2 nd, 3 rd and 4 th symbols of a PUCCH subframe of a normal CP, and a PUCCH format 2/2a/2b, where DMRSs occupy the 3 rd symbol of a PUCCH subframe of a normal CP.

Then when determining the remaining spatial capacity of the PUCCH subframe carrying aperiodic CSI, the terminal determines the remaining spatial capacity according to the total number of symbols and the number of symbols occupied by the carried resources, where the carried resources include multiple types, for example, see the PUCCH subframe shown in fig. 7, and the carried resources in the PUCCH subframe include DMRS and aperiodic CSI.

For example, as shown in fig. 8, the terminal determines that a PUCCH subframe shown in fig. 8 generates a reporting collision, where the number of symbols of the PUCCH subframe is 14, the number of symbols occupied by the aperiodic CSI and the DMRS is 6symbol, and the remaining number of symbols is 14-6-8, 8 symbol. It can be understood that the size characterizing the UCI information is data bits. When the terminal selects part or all of the information from the UCI according to the 8 symbols, an optional mode is that the terminal firstly modulates the information contained in the UCI and determines the number of symbols occupied by the modulated information; another optional paradigm is that the terminal determines the number of data bits that can be carried and corresponding to the number of remaining symbols according to the modulation mode of the aperiodic CSI, for example, the modulation mode of the aperiodic CSI is BPSK, that is, 1 symbol is occupied by modulated 1-bit data, then the maximum number of bits of information that can be carried by 8 symbols is 8 bits, and the terminal selects UCI information according to the maximum number of bits.

The terminal selects information from the UCI according to the remaining spatial capacity in the following manner:

in the first method, it is assumed that the modulation method of the aperiodic CSI is QPSK, that is, the number of OFDM symbols occupied by 2-bit data after modulation is 2 symbols, and the size of the resource that can be carried by 8 symbols is 8 symbols by 2 bits/symbol being 16 bits.

The size of the UCI generating reporting collision is assumed to be 10 bits, and 10 bits is less than 16 bits, that is, the terminal may insert all the information of the UCI into the PUCCH subframe and report the UCI together with the aperiodic CSI.

And secondly, the terminal determines information contained in UCI modulated by using a modulation mode of the aperiodic CSI, the number of OFDM symbols occupied by the modulated UCI is 5 symbols, and the 5 symbols are less than 8 symbols, namely, the terminal can insert all the information of the UCI into the PUCCH subframe and report the information together with the aperiodic CSI.

The above modulation scheme is merely an example, and does not limit the specific modulation scheme of the aperiodic CSI in the present application. The modulation mode of the terminal for the aperiodic CSI is determined by configuration information issued by the base station.

It should be noted that the PUCCH subframe described above contains the aperiodic CSI and some fixed information, such as DMRS, which is only an example. The loaded resources in the PUCCH subframe may further include indication information for indicating whether UCI information is inserted and/or a kind of inserted UCI information in the PUCCH subframe loaded with aperiodic CSI, which will be described below.

Further, in order to meet the requirement of high reliability and low delay in a 5G scenario (such as a URLLC scenario), the terminal may also determine the maximum spatial capacity of the PUCCH subframe that meets the delay and reliability requirements according to the delay requirement and the reliability requirement, where the maximum spatial capacity may be the total number of symbols in the PUCCH subframe or may be less than the total number of symbols in the PUCCH subframe. As shown in fig. 9, the maximum space capacity of the PUCCH subframe satisfying the delay and reliability requirements is determined for the terminal, and it can be understood that no content is carried on symbol 11, symbol 12, and symbol 13 on the PUCCH subframe shown in fig. 9.

The terminal determines the maximum space capacity of the PUCCH subframe meeting the delay and reliability requirements in many ways, and the following are listed as follows:

the determination method is as follows: the terminal determines the maximum space capacity of the PUCCH sub-frame according to the current system parameters;

the total time delay of the PUCCH sub-frame is the sum of the sending time delay, the propagation time delay, the processing time delay and the queuing time delay, wherein the sending time delay is the time required from the sending of the first bit of the PUCCH sub-frame to the completion of the sending of the last bit of the frame, and the sending time delay can be calculated by the following formula:

the transmission time delay is frame length (b)/channel bandwidth (b/s);

therefore, the transmission delay of the PUCCH sub-frames is determined by the frame length and the channel bandwidth, and as the propagation delay, the processing delay and the queuing delay of the system are approximately the same in a certain time and the sum of the propagation delay, the processing delay and the queuing delay is a constant value in a certain threshold range, the terminal can determine the transmission delay according to the length of each PUCCH sub-frame transmitted in a period of time and the corresponding total delay and determine the maximum bit number which can be carried by the PUCCH sub-frame meeting the delay requirement according to the current channel bandwidth.

Determining a second mode: the terminal determines the maximum space capacity of the PUCCH sub-frame through a neural network model;

the terminal determines the maximum space capacity of a PUCCH subframe which simultaneously meets the time delay requirement and the reliability requirement under the current channel condition through a neural network model;

the neural network model can be obtained by training channel information, interference information, network load conditions, modulation modes, subframe lengths, corresponding transmission delay and bit error rates and the like.

The output layer of the neural network model may be a neuron, that is, the maximum spatial capacity value satisfying both the delay requirement and the reliability requirement, or the output layer of the neural network model includes two neurons, which are the maximum spatial capacity of the PUCCH subframe satisfying the delay requirement and the maximum spatial capacity of the PUCCH subframe satisfying the reliability requirement, respectively.

Determining a third mode: the terminal determines the maximum space capacity of the PUCCH sub-frame in a table look-up mode;

the terminal establishes a mapping relation list of the maximum space capacity of the PUCCH sub-frame which meets the time delay requirement and the reliability requirement and corresponds to different scenes, and determines the maximum space capacity of the PUCCH sub-frame corresponding to the current scene in a mode of inquiring the mapping relation list.

The information of the mapping relation list is obtained in advance through a large number of data experiments. Different scenes are distinguished by parameters such as the current channel condition of the terminal, the network load condition, interference information, a modulation mode and the like.

In order to determine the maximum space capacity of the PUCCH subframe, the terminal determines the remaining space capacity according to the maximum space capacity and the number of symbols occupied by the carried resources in the PUCCH subframe, and selects part or all of information from the UCI according to the remaining space capacity to insert into the PUCCH subframe for reporting.

When UCI information is selected, if the size of UCI is not larger than the residual space capacity, the terminal places all the modulated UCI in PUCCH subframes, and if the size of UCI is larger than the residual space capacity, the terminal also needs to select partial information from the UCI according to the residual space capacity or selects to discard the UCI when the information contained in the UCI cannot be reported partially.

For example, whether the terminal selects partial information or discards UCI is determined according to specific information included in the UCI, the UCI may include one or more of SR, ACK/NACK, RI, CQI, and PMI, and then, according to different information included in the UCI, there are a plurality of cases where reporting collision occurs between aperiodic CSI and UCI, where one possible case is that the aperiodic CSI collides with UCI including one type of information, for example: if the bit number of the SR is greater than the maximum bit number that can be carried by the remaining symbols in the PUCCH subframe, it can be understood by those skilled in the art that the SR splitting reporting is meaningless, and therefore the terminal selects to discard the SR instead of selecting part of SR information for reporting. Another possible scenario is that aperiodic CSI collides with UCI containing multiple information types, such as: the UCI comprises SR and ACK, and when the aperiodic CSI collides with the UCI, the aperiodic CSI actually collides with the SR and the ACK. The terminal selects partial information in the SR and ACK according to the remaining spatial capacity. The following is illustrated by specific examples:

example 1: the aperiodic CSI collides with the SR;

the data bits of the SR are typically multi-bits, e.g., as defined in the 5GNR standard 38.213, with the size of the SR being

Wherein K represents the number of SRs; []Indicating rounding up.

The UCI only includes SR, and when the SR and the aperiodic CSI report collision in the same PUCCH subframe, the possible situations are as follows:

example 1: the rest space capacity can bear the modulated SR, and the SR and the aperiodic CSI are completely reported;

because the SR is resource scheduling information requested by the terminal to the base station, if the base station does not resolve the SR request sent by the terminal, the RB resource cannot be allocated to the terminal, and the UE cannot transmit data to the base station without a corresponding terminal resource, thereby causing an increase in delay.

Example 2: the remaining space capacity cannot bear the modulated SR, the terminal discards the SR, and only reports the aperiodic CSI.

If the SR cannot be completely reported, the base station cannot demodulate useful information, and therefore, if the remaining spatial capacity cannot carry the modulated SR, the terminal selects to discard the SR and only reports the aperiodic CSI.

Example 2: aperiodic CSI and ACK/NACK collisions;

unlike SR, the data bit of one ACK/NACK is small, typically 1bit or 2 bits.

The UCI only includes ACK/NACK, and when the ACK/NACK and the aperiodic CSI report collision occur in the same PUCCH subframe, the possible situations are as follows:

example 1: determining that the number of bits which can be carried by the residual space capacity is not less than the number of bits of ACK/NACK according to the modulation mode of the aperiodic CSI, and completely reporting the ACK/NACK and the aperiodic CSI;

example 2: determining the bit number which can be carried by the residual space capacity and is less than the bit number of ACK/NACK according to the modulation mode of the aperiodic CSI, and selecting partial ACK/NACK from the total ACK/NACK by the terminal to report the aperiodic CSI;

for example, assuming that the bit number that can be carried by the remaining spatial capacity is 10 bits, if the UCI only includes ACK/NACK and the bit number of the included multiple ACK/NACK is 16 bits, assuming that one ACK/NACK is 1bit, the total number of ACK/NACK is 16, the terminal may select a partial ACK/NACK from the 16 ACK/NACKs and report the non-periodic CSI, and there are various ways for the terminal to select the partial ACK/NACK, which are listed as follows:

the selection mode is as follows: randomly selecting;

with the combination of the above embodiments, the terminal randomly selects 10 ACK/NACKs from the 16 ACK/NACKs, discards 6 ACK/NACKs, modulates the selected 10 ACK/NACKs according to the modulation method of the aperiodic CSI, and reports the modulated ACK/NACK together with the aperiodic CSI through the PUCCH subframe.

And a second selection mode: selecting according to the priority of each ACK/NACK;

the terminal determines the priority of each ACK/NACK according to the priority indication identifier or the sequence of the ACK/NACK or the corresponding cell identifier, and selects the first 10 ACK/NACKs with high priority according to the determined priority sequence, such as: and if 10 ACK/NACK in the 16 ACK/NACK is the primary cell and 6 ACK/NACK is the secondary cell, the ACK/NACK of the primary cell is selected to be reported together with the non-periodic CSI.

If the determined number of the ACK/NACKs with the higher priority exceeds the remaining spatial capacity, the ACK/NACKs with the higher priority may be randomly selected again, for example, if the number of the ACK/NACKs of the primary cell is determined to be 15, and the number of the ACK/NACKs of the secondary cell is determined to be 1, 10 ACK/NACKs from the ACK/NACKs of the 15 primary cells may be randomly selected to report the aperiodic CSI.

Since each ACK/NACK corresponds to one downlink data packet, if the base station does not receive an ACK signal, the same data is repeatedly transmitted in the following subframe, causing additional signaling overhead, and the more the number of ACK/NACK signals discarded by the terminal is, the more the signaling overhead may be caused. Therefore, if part or all of the ACK/NACK and the aperiodic CSI are reported simultaneously through the same PUCCH subframe, normal reporting of the aperiodic CSI can be ensured, and the problem of increased signaling overhead caused by discarding the ACK/NACK is solved.

It should be noted that, when the aperiodic CSI and the ACK/NACK collide in the same PUCCH subframe, and the number of bits that can be carried by the remaining spatial capacity is smaller than the ACK/NACK, the terminal may also choose to discard the ACK/NACK completely, and only report the aperiodic CSI, which is only an example, and the present invention does not limit the selection manner after any UCI information collides with the aperiodic CSI.

Example 3: collision of the aperiodic CSI with the periodic CSI;

the periodic CSI comprises one or more of RI, PMI and CQI, the aperiodic CSI also comprises one or more of RI, PMI and CQI, the aperiodic CSI is different from the periodic CSI in a reporting period, the aperiodic CSI is reported irregularly, and the periodic CSI is reported periodically;

if reporting conflict occurs between the aperiodic CSI and the periodic CSI, the possible situations are as follows:

example 1: determining that the number of bits which can be carried by the residual space capacity in the PUCCH subframe is not less than the periodic CSI according to the modulation mode of the aperiodic CSI, and completely reporting the periodic CSI and the aperiodic CSI;

example 2: the periodic CSI only comprises one of CQI, PMI and RI, the number of bits which can be carried by the residual space capacity in the PUCCH subframe is determined to be less than the periodic CSI according to the modulation mode of the aperiodic CSI, the terminal discards the periodic CSI and only reports the aperiodic CSI;

similar to the SR, the number of bits occupied by the CQI, PMI, and RI themselves is large, and the CQI, PMI, and RI cannot be reported separately, so that the number of bits that can be carried by the remaining spatial capacity in the PUCCH subframe is smaller than any one of the CQI, PMI, or RI, and the periodic CSI is selected to be discarded directly.

For example, the periodic CSI colliding with the aperiodic CSI only contains RI, and assuming that the number of bits that can be carried by the remaining spatial capacity is 10 bits and the size of RI is 12 bits, if the RI is split and reported, the base station cannot demodulate the complete information of RI, and therefore, the RI is discarded, and only the aperiodic CSI is reported.

Example 3: the periodic CSI only comprises a plurality of CQI, PMI and RI, the number of bits which can be carried by the residual space capacity in the PUCCH subframe is determined to be less than the bit number of any information contained in the periodic CSI according to the modulation mode of the aperiodic CSI, the terminal discards the periodic CSI and only reports the aperiodic CSI;

example 4: and the periodic CSI only contains multiple types of CQI, PMI and RI, the bit number which can be carried by the residual space capacity in the PUCCH subframe is determined to be not less than the bit number of one type of information contained in the periodic CSI according to the modulation mode of the aperiodic CSI, and the terminal selects the information and the aperiodic CSI to report.

In another possible case, the bit number of the information included in the periodic CSI is smaller than the bit number that can be carried by the remaining spatial capacity in the PUCCH subframe, and the terminal needs to select one of the information for reporting, where the selection method may refer to the above selection method, which is not described herein again.

For example, as shown in fig. 10(a), the terminal determines that a reporting collision occurs at a PUCCH subframe shown in fig. 10(a), where the total spatial capacity of the PUCCH subframe is 14 symbols, the carried resources are DMRS and aperiodic CSI, the carried resources occupy 8 symbols, and the remaining spatial capacity is 6 symbols;

as shown in fig. 10(b), the periodic CSI at the position where the reporting collision occurs is adjusted by using the modulation of the aperiodic CSI for the terminal, where the periodic CSI includes RI and PMI, PI is 6bit, PMI is 8bit, it is assumed that the modulation mode of the aperiodic CSI is QPSK, the number of symbols occupied by RI after QPSK modulation is 3 symbols, and the number of symbols occupied by PMI after QPSK modulation is 4 symbols.

The total number of symbols occupied by the RI and the PMI is 7, and the number of symbols left in a PUCCH subframe is 6 symbols, so that the terminal cannot completely report the RI and the PMI, but can select any one of RI or PMI for reporting, namely, an optional selection mode, and the terminal randomly selects one of RI and PMI for reporting; in another alternative, the terminal selects according to the priority of the information, such as: and the priority specified by the protocol is SR & gt RI & gt CQI/PMI & gt ACK/NACK, and the terminal determines to select RI and non-periodic CSI to report according to the specified priority sequence. As shown in fig. 10(c), RI multiplexes the same PUCCH subframe with non-periodicity.

Example 5: and the periodic CSI only contains multiple types of CQI, PMI and RI, the bit number which can be carried by the residual space capacity in the PUCCH subframe is determined to be not less than the bit number of at least one type of information contained in the periodic CSI according to the modulation mode of the aperiodic CSI, and the terminal selects the at least one type of information to report the aperiodic CSI.

Because the periodic CSI reflects the state of a downlink channel and can guide the base station to adopt which modulation mode and code rate, if the CSI information is discarded, the base station cannot change the corresponding transmission mode in time, the original transmission mode is still adopted, and if the channel condition becomes good, the data volume transmitted in the same time is reduced; if the channel condition is poor, the bit error rate is increased, and the reliability requirement of the data may not be met. Therefore, the periodic CSI and the aperiodic CSI are reported simultaneously through the same PUCCH subframe, so that normal reporting of the aperiodic CSI can be ensured, and the problem of reliability or resource waste possibly caused by the periodic CSI is reduced.

After the terminal selects part or all of the information from the UCI in the mode, the selected information is modulated by using the modulation mode of the aperiodic CSI, and the selected information and the aperiodic CSI are reported together through the same PUCCH subframe.

Optionally, the terminal may further carry indication information in the PUCCH subframe, where the indication information is used to indicate whether UCI information and/or a type of the inserted UCI information is inserted in the PUCCH subframe carrying the aperiodic CSI;

illustratively, the indication information is 1bit, such as: when the indication information is 0, indicating that UCI is not inserted into the PUCCH subframe carrying the aperiodic CSI, namely, the aperiodic CSI and the UCI information do not multiplex the PUCCH subframe; when the indication information is 1, the indication information indicates that the UCI is inserted into the PUCCH subframe carrying the aperiodic CSI, namely, the aperiodic CSI and UCI information multiplexing PUCCH subframe.

As another example, the indication information is 3 bits, such as: when the indication information is 000, indicating that the aperiodic CSI and the UCI do not multiplex PUCCH subframes; when the indication information is 001, the aperiodic CSI and CQI multiplexing PUCCH subframe is represented; when the indication information is 010, the aperiodic CSI and PMI multiplexing PUCCH subframes are represented; when the indication information is 011, the aperiodic CSI and RI multiplexing PUCCH subframe is represented; when the indication information is 100, the aperiodic CSI and SR multiplexing PUCCH subframes are represented; when the indication information is 101, the indication information indicates that the aperiodic CSI and the ACK/NACK are multiplexed on the PUCCH subframe.

For example, the indication information may be located in any one symbol of the PUCCH subframe that does not carry resources, such as: the last symbol of the PUCCH subframe.

As shown in fig. 11, a schematic view of a complete process for reporting information after collision between aperiodic CSI and UCI provided in the embodiment of the present invention includes the following steps:

step 1100: the terminal detects that aperiodic CSI is reported;

step 1101: the terminal judges whether UCI is still reported at the PUCCH subframe position reporting the aperiodic CSI; if so, go to step 1102; otherwise, go to step 1103;

step 1102: the terminal determines the residual space capacity in the PUCCH subframe;

step 1102: the terminal only reports the aperiodic CSI and discards the UCI;

step 1104: the terminal judges whether the size of the UCI is larger than the residual space capacity; if so, perform step 1105; otherwise, go to step 1006;

step 1105: the terminal multiplexes all UCI and non-periodic CSI;

step 1106: the terminal sorts the information according to the priority of the information contained in the UCI from big to small;

step 1107: the terminal judges whether the information which is not larger than the residual space capacity exists according to the priority sequence; if so, go to step 1109; otherwise, go to step 1108;

step 1108: the terminal only reports the aperiodic CSI and discards the UCI;

step 1109: and the terminal multiplexes the selected partial information and the aperiodic CSI and discards the rest of the UCI.
