Description

Information feedback and receiving method and equipment

Technical Field

The present invention relates to the field of wireless communications, and in particular, to an information feedback and receiving method and apparatus.

Background

In Long Term Evolution (LTE) and previous wireless communication systems, there is only one carrier in a cell, and the maximum bandwidth in the LTE system is 20MHz, as shown in fig. 1:

in an LTE Advanced (LTE-a) system, the peak rate of the system is greatly improved compared to the LTE system, and it is required to achieve 1Gbps downlink and 500Mbps uplink. The peak rate requirement cannot be achieved if only one carrier with a maximum bandwidth of 20MHz is used. Therefore, the LTE-a system needs to extend a bandwidth that can be used by a terminal (UE), thereby introducing a Carrier Aggregation (CA) technique that aggregates a plurality of continuous or discontinuous carriers under the same base station (eNB) while serving the UE to provide a required rate. These aggregated carriers are also called Component Carriers (CCs). Each cell may be a component carrier, and cells (component carriers) under different enbs cannot be aggregated. In order to ensure that the UE of the LTE system can operate under each aggregated carrier, each carrier does not exceed 20MHz at maximum. The CA technology for LTE-A is shown in FIG. 2.

There are 4 carriers that can be aggregated under the base station of the LTE-a system shown in fig. 2, and the base station can perform data transmission with the UE on the 4 carriers simultaneously, so as to improve the system throughput.

At most 2 component carriers are supported for aggregation in LTE-a release 10(Rel-10), while at most 5 component carriers are supported for aggregation in LTE-a release 11 (Rel-11).

The acknowledgement/negative acknowledgement (ACK/NACK) information feedback scheme is as follows:

for a Frequency Division Duplex (FDD) system, the UE receives downlink data in subframe n-4, and feeds back a signaling indicating whether the data on the downlink subframe needs to be retransmitted or not, i.e., ACK/NACK information, in uplink subframe n. And when the carriers are aggregated, the ACK/NACK information corresponding to a plurality of downlink carriers in the subframe n-4 is fed back in the uplink subframe n at the same time.

For a Time Division Duplex (TDD) system, the UE may feed back ACK/NACK information corresponding to multiple downlink subframes in the same uplink subframe, that is, the UE receives downlink data in a downlink subframe n-K and feeds back corresponding ACK/NACK information in an uplink subframe n, where K belongs to K, and a value of the set K is related to uplink and downlink configuration of the system and a specific subframe number, as shown in table 1.

TABLE 1

In table 1, a plurality of radio frames are sequentially arranged, that is, if the last subframe in the radio frame a is K, the first subframe in the radio frame a +1 is K +1, and table 2 only gives the case of K for each uplink subframe by taking one radio frame as an example, where n-K < 0 indicates the downlink subframe in the previous radio frame.

The ACK/NACK information may be transmitted using a Physical Uplink Control Channel (PUCCH), and there are multiple feedback manners, and PUCCH formats used by different feedback manners are different, which specifically includes: a transmission scheme based on PUCCH formats 1a/1b, a transmission scheme based on channel selection of PUCCH format 1b, and a multiplexing transmission scheme based on PUCCH format 3.

The PUCCH format 1a/1b can carry 1 or 2 bits of information; channel selection based on PUCCH format 1b can carry 4 bits of information at most; PUCCH format 3 can carry a large amount of information, up to 48 coded bits. When ACK/NACK information is transmitted using PUCCH format 3, the specifically used PUCCH is signaled to the UE by the base station.

The scheme of Channel State Information (CSI) feedback is as follows:

in the LTE system, the UE needs to feed back CSI to the base station. And the base station performs downlink dynamic scheduling by using the CSI fed back by the UE.

According to different trigger mechanisms, CSI is divided into two categories: periodic CSI and aperiodic CSI. The reporting period of the periodic CSI and the offset in the period are configured semi-statically by a base station through Radio Resource Control (RRC) signaling, and the UE transmits the CSI in a specific uplink subframe according to configuration information. And in the subframe without uplink data transmission, reporting the periodic CSI by using a PUCCH.

In the carrier aggregation system of LTE-A Rel-10, parameters of periodic CSI of different component carriers are configured independently, UE only feeds back the periodic CSI of one component carrier in each reporting subframe, and if the periodic CSI of a plurality of component carriers collides, the periodic CSI corresponding to the highest priority is fed back according to a preset priority.

The aperiodic CSI is triggered by a base station through a downlink scheduling signaling, the UE reports the CSI only after receiving the triggering signaling, and transmits the aperiodic CSI by using a Physical Uplink Shared Channel (PUSCH). The UE can report the aperiodic CSI of a plurality of component carriers simultaneously according to the triggering condition of the base station.

The scheme for simultaneously feeding back the ACK/NACK information and the periodic CSI is as follows:

in an LTE system, a base station configures whether UE supports the capability of simultaneously transmitting ACK/NACK information and CSI by using a PUCCH in a high-level signaling mode, and for a terminal which cannot simultaneously transmit the ACK/NACK information and the CSI, the CSI is discarded when the two signaling are collided.

In the carrier aggregation system of LTE-a Rel-10, even if the base station configures that the UE can simultaneously transmit ACK/NACK information and CSI, when the UE receives downlink data on multiple component carriers, the CSI will be discarded if there is no PUSCH in the corresponding uplink subframe. That is, the UE can only feed back the ACK/NACK information and the CSI to the base station in the PUCCH when the UE receives downlink data on the primary carrier and the configuration can simultaneously transmit the ACK/NACK information and the CSI.

The scheme of PUCCH power control is as follows:

Detailed Description

In order to implement a coding scheme when receiving response information and CSI are fed back simultaneously, an embodiment of the present invention provides an information feedback method, where a terminal performs channel coding on receiving response information to be fed back, aggregates obtained coding information and CSI to be fed back, performs channel coding on obtained aggregated information, and feeds back the obtained receiving response information and CSI combined coding information.

Referring to fig. 3, an information feedback method provided in an embodiment of the present invention includes the following steps:

step 30: the terminal carries out channel coding on the A bit receiving response information to be fed back to obtain B bit coding information, wherein B is not less than A;

step 31: the terminal aggregates the coding information of the B bit and the CSI of the C bit to be fed back to obtain aggregated information of a D bit, wherein D is equal to the sum of B and C;

step 32: the terminal performs channel coding on the aggregation information of the D bits to obtain joint coding information of the received response information and the CSI;

step 33: and the terminal feeds back the joint coding information to the base station through the PUCCH.

In step 30, the a-bit reception response information to be fed back is obtained by compressing the original reception response information (i.e., the reception response information generated according to the downlink data reception condition) by the terminal.

The a-bit reception response information to be fed back may correspond to a plurality of downlink subframes, or to a plurality of downlink carriers, or to a plurality of codewords, or to a plurality of downlink subframes and a plurality of downlink carriers, or to a plurality of downlink subframes and a plurality of codewords, or to a plurality of downlink carriers and a plurality of codewords, or to a plurality of downlink subframes, a plurality of downlink carriers, and a plurality of codewords.

In step 31, the CSI of the C bit to be fed back is the compressed CSI of the C bit obtained by the terminal performing difference or partial discarding processing on the original CSI (i.e., CSI generated according to the channel state).

The CSI of the C bits to be fed back may be CSI of a single carrier or CSI of multiple carriers.

In step 30, the terminal performs channel coding on the a-bit reception response information to be fed back to obtain B-bit coding information, which may be specifically implemented as follows:

and the terminal performs channel coding on the A-bit receiving response information to be fed back by adopting a preset coding mode to obtain B-bit coding information. The coding mode satisfies the following conditions: if each information bit of the a-bit reception response information corresponds to NACK, the B-bit encoded information generated after encoding is all 0.

The encoding method may be: repetition coding, or Reed Muller (RM) coding.

The terminal can determine the value of B as follows: determining the value of B according to the signaling indication of the base station; or determining the value of B corresponding to the current value of A according to the preset corresponding relation between the value of A and the value of B; or, determining the value of B according to preset information of the system. Specifically, the following three examples may be included:

firstly, a terminal encodes the receiving response information of the bit A to be fed back by adopting a repeated encoding mode to obtain the encoding information of the bit B;

for example, the following steps are carried out:

the coding mode is a repetition coding mode, A is 4, and the receiving response information to be fed back is a₁，a₂，a₃，a₄；

If the system is preset or the base station indicates that B is 10 through the signaling, the coded information obtained by coding the received response information in a repeated coding mode is B₁，b₂，...b_B＝a₁，a₂，a₃，a₄，a₁，a₂，a₃，a₄，a₁，a₂；

If the system preset coding is repeated for 2 times, B is Ax 2 is 8, and the coded information obtained by coding the receiving response information by adopting the repeated coding mode is B₁，b₂，...b_B＝a₁，a₂，a₃，a₄，a₁，a₂，a₃，a₄Or a₁，a₁，a₂，a₂，a₃，a₃，a₄，a₄。

Secondly, the terminal adopts an RM coding mode to code the A bit receiving response information to be fed back, and carries out rate matching on the obtained coded information to obtain the B bit coded information.

For example, the following steps are carried out:

the encoding mode is an RM encoding mode, the information length output by the RM encoder is fixed to be N-10, A-4, and the receiving response information to be fed back is a₁，a₂，a₃，a₄The received response information is coded by RM coding mode to obtain coded information

And further carrying out rate matching on the coded information according to the value of the B. And the rate matching is to obtain an output sequence with a corresponding length by repeating, truncating or puncturing the sequence according to the determined output length.

If the system presets or the base station indicates that B is 15 through signaling, the information obtained after rate matching is carried out on the coded information is $b_1,b_2,...b_B={\tilde{a}}_1,{\tilde{a}}_2,{\tilde{a}}_3,...,{\tilde{a}}_{10},{\tilde{a}}_1,{\tilde{a}}_2,{\tilde{a}}_3,{\tilde{a}}_4,{\tilde{a}}_5;$

If the system presets B ═ a × 2 ═ 8, the information obtained by rate matching the coded information is $b_1,b_2,...b_B={\tilde{a}}_1,{\tilde{a}}_2,{\tilde{a}}_3,...,{\tilde{a}}_8.$

Thirdly, the terminal adopts an RM coding mode to code the receiving response information of the bit A to be fed back to obtain the coding information of the bit B;

for example, the following steps are carried out:

the coding mode is RM codingIn this mode, the length of the information output by the RM encoder is fixed to N-10, a-4, and the reception response information to be fed back is a₁，a₂，a₃，a₄The received response information is coded by RM coding mode to obtain coded information

If the value of B is 10, then the coding is finished without performing rate matching on the coded information.

In step 31, the terminal may use a cascade connection mode or an interleaving aggregation mode to aggregate the coding information of the B bit and the CSI of the C bit to be fed back, so as to obtain the aggregation information of the D bit.

Specifically, when a cascade mode is adopted, the terminal cascades the coding information of the B bit and the CSI of the C bit to be fed back according to a cascade sequence predefined by a system or indicated by a base station through signaling to obtain aggregation information of the D bit;

for example, fig. 5A shows an example of concatenating B-bit coded information and C-bit CSI when the concatenation order is that the reception response information is before and the CSI is after.

And during the interleaving aggregation mode, the terminal performs interleaving aggregation on the coding information of the B bit and the CSI of the C bit to be fed back according to the interleaving mode predefined by the system or indicated by the base station through signaling to obtain the aggregation information of the D bit.

For example, the interleaving manner is: an example of dividing the reception response information and the CSI into a groups (a is an integer greater than 1), alternately mapping each group of reception response information and CSI, and interleaving and aggregating the coding information of the B bits and the CSI of the C bits is shown in fig. 5B, where a is 14.

In step 32, when D is greater than the preset threshold, the terminal performs channel coding on the aggregation information of D bits to obtain joint coding information of the reception response information and the CSI, which may be specifically implemented as follows:

and the terminal divides the aggregation information of the D bits into a plurality of groups, respectively codes the information in each group, and aggregates the information obtained after coding in each group to obtain the joint coding information. Wherein D is an integer greater than 1.

The above-mentioned division of the aggregation information of D bits into multiple groups may be implemented in various ways, where one way is to, for each information bit in the a-bit reception response information, divide all the coded bits in the coded information corresponding to the information bit in B bits into the same group. For example, the a-bit reception response information is a₁，a₂，a₃，a₄When the repetition coding method is adopted, the coding information of B bits is a₁，a₂，a₃，a₄，a₁，a₂，a₃，a₄，a₁，a₂Grouping the encoded information of B bit and the aggregated information obtained by aggregating the CSI of C bit, and then grouping the same a of x_xWithin the same packet, x takes on a value between 1 and 4.

Of course, the way of dividing the D-bit aggregation information into multiple groups is not limited to the above way, and an odd-even grouping way may also be adopted, in which the information bits on the odd bits are grouped into one group and the information bits on the even bits are grouped into another group; or the information bits of the first half part are divided into one group and the information bits of the rest part are divided into another group by adopting an equal division grouping mode, and the like.

When the information in each packet is encoded, a repetition coding method or an RM coding method may be used, which is not described herein again.

When the information obtained after the intra-coding of each packet is aggregated, a cascade mode or an interleaving aggregation mode may be adopted, which is not described herein again.

In order to enable the bit number of the fed-back joint coding information not to exceed the bit number of information which can be carried by the PUCCH, after information obtained by coding the information in each group is aggregated, the rate matching can be carried out on the aggregated information; or after the information in each packet is coded, rate matching may be performed on the obtained coded information, and then the information after rate matching is aggregated, so that the bit number of the obtained joint coded information does not exceed the bit number of information that can be carried by the PUCCH.

When D is not greater than the preset threshold, the terminal performs channel coding on the aggregation information of D bits to obtain joint coding information of the reception response information and the CSI, which may be specifically implemented as follows:

and the terminal adopts a repetition coding mode or an RM coding mode to code the aggregation information of the D bits to obtain the joint coding information of the receiving response information and the CSI.

In order to enable the bit number of the fed-back joint coding information not to exceed the bit number of information which can be carried by the PUCCH, the joint coding information obtained after coding can be subjected to rate matching.

In step 33, the terminal feeds back the joint coding information to the base station through the PUCCH, and the specific implementation thereof may be as follows:

first, the terminal determines a power control parameter n of the PUCCH_HARQIs A or B, n_CQIThe value of (A) is C; n is_HARQNumber of effective messages, n, indicating reception of response messages_CQIA number of bits representing the CSI;

then, the terminal is according to n_HARQAnd n_CQIDetermines the power control parameter h (n)_CQI，n_HARQ，n_SR)；h(n_CQI，n_HARQ，n_SR) Is the adjustment amount related to the PUCCH format;

finally, the terminal bases on h (n)_CQI，n_HARQ，n_SR) And determining the transmission power of the PUCCH, and feeding back the joint coding information to the base station through the PUCCH according to the transmission power.

For example, the following steps are carried out:

UE calculates power control parameter n of PUCCH_HARQA or n_HARQ＝B；

When PUCCH adopts PUCCH format 3:

if the higher layer configuration PUCCH is transmitted using 2 antenna ports, or the CSI/HARQ-ACK/SR information transmitted by the UE is greater than 11 bits, then, $h(n_{\mathrm{CQI}},n_{\mathrm{HARQ}},n_{\mathrm{SR}})=\frac{n_{\mathrm{HARQ}}+n_{\mathrm{SR}}+n_{\mathrm{CQI}}-1}{3};$

if not, then, $h(n_{\mathrm{CQI}},n_{\mathrm{HARQ}},n_{\mathrm{SR}})=\frac{n_{\mathrm{HARQ}}+n_{\mathrm{SR}}+n_{\mathrm{CQI}}-1}{2};$

then, the formula (1) in the background section is based on h (n)_CQI，n_HARQ，n_SR) And determining the transmission power of the PUCCH, and feeding back the joint coding information to the base station through the PUCCH according to the transmission power.

The PUCCH in the method may adopt PUCCH format 2, PUCCH format 3, or a PUCCH format with information carrying capacity defined after LTE release 11 no less than PUCCH format 3.

In order to implement a decoding scheme of a receiving side when receiving response information and CSI are fed back simultaneously, an embodiment of the present invention provides an information receiving method, in which a base station receives joint coding information of the receiving response information and the CSI fed back by a terminal through a PUCCH, performs channel decoding on the joint coding information, extracts coding information and CSI of the receiving response information in obtained aggregation information, and then performs channel decoding on the coding information of the receiving response information to obtain the receiving response information.

Referring to fig. 4, an information receiving method provided in the embodiment of the present invention includes the following steps:

step 40: the base station receives the joint coding information of the receiving response information and the CSI fed back by the terminal through the PUCCH;

step 41: and the base station decodes the joint coding information to obtain the receiving response information of the A bit and the CSI of the C bit. The joint coding information is obtained by performing channel coding on B-bit coding information obtained by performing channel coding on A-bit receiving response information and CSI (channel state information) of C-bit, and then performing channel coding on the obtained aggregation information, wherein B is not less than A.

Specifically, the a-bit reception response information is the reception response information obtained by compressing the original reception response information by the terminal.

The a-bit reception response information may correspond to multiple downlink subframes, or to multiple downlink carriers, or to multiple codewords, or to multiple downlink subframes and multiple downlink carriers, or to multiple downlink subframes and multiple codewords, or to multiple downlink carriers and multiple codewords, or to multiple downlink subframes, multiple downlink carriers, and multiple codewords.

The CSI of the C bit is a compressed CSI of the C bit obtained by the terminal performing a difference or partial discarding process on the original CSI. The CSI of C bits may be CSI of a single carrier or CSI of multiple carriers.

In step 41, the base station may perform a decoding operation on the received joint coding information according to the coding mode adopted by the terminal, so as to obtain a bit of reception response information and C bit of CSI. The specific implementation can be as follows:

specifically, if the terminal does not adopt a block coding scheme, the base station decodes the joint coding information to obtain a bit of reception response information and C bit of CSI information, and the specific implementation may adopt the following two methods:

the method comprises the following steps: the base station firstly carries out channel decoding on the joint coding information to obtain the aggregation information of the D bit; then, the base station extracts the coding information of the B bit receiving response information and the CSI of the C bit in the D bit aggregation information; and finally, the base station performs channel decoding on the coded information of the B-bit receiving response information to obtain A-bit receiving response information, wherein B is not less than A.

Specifically, the base station performs channel decoding on the joint coding information to obtain the aggregation information of the D bits, and the specific implementation may adopt the following two ways:

first, when the terminal encodes the D-bit aggregation information by using the repetition coding scheme or the RM coding scheme:

the base station performs channel decoding on the combined coding information according to the coding mode adopted by the terminal to obtain the aggregation information of the D bit;

secondly, after the terminal encodes the aggregation information of the D bits, and rate-matches the joint coding information obtained after encoding:

and the base station performs reverse rate matching on the combined coding information according to a rate matching mode adopted by the terminal, and performs channel decoding on the information obtained by the reverse rate matching to obtain the aggregation information of the D bit.

Specifically, the base station extracts the coding information of the reception response information of B bits and the CSI of C bits from the aggregation information of D bits, and the specific implementation may be as follows:

the base station extracts the coding information of the B-bit reception response information and the CSI of the C-bit from the aggregation information of the D-bit according to the information aggregation mode adopted by the terminal, which is an inverse process of step 31 at the terminal side.

Specifically, the base station performs channel decoding on the coded information of the B-bit reception response information to obtain the a-bit reception response information, and the specific implementation may adopt the following two ways:

firstly, when the terminal does not perform rate matching in the process of performing channel coding on the a-bit reception response information to be fed back:

the base station carries out channel decoding on the coded information of the B-bit receiving response information according to the coding mode adopted by the terminal to obtain A-bit receiving response information;

secondly, when the terminal performs channel coding on the a-bit reception response information to be fed back and performs rate matching on the obtained coding information:

and the base station performs inverse rate matching on the B-bit receiving response information according to the rate matching mode adopted by the terminal, and performs channel decoding on the information obtained by inverse rate matching according to the coding mode adopted by the terminal to obtain A-bit receiving response information.

The second method comprises the following steps: the base station directly obtains the receiving response information of the A bit and the CSI of the C bit after performing channel decoding on the joint coding information for the first time, and the specific implementation can adopt the following two modes:

first, when the terminal encodes the D-bit aggregation information by using the repetition coding scheme or the RM coding scheme:

the base station performs channel decoding on the combined coding information for the first time according to the coding mode adopted by the terminal to obtain the receiving response information of the A bit and the CSI of the C bit;

secondly, after the terminal encodes the aggregation information of the D bits, and rate-matches the joint coding information obtained after encoding:

and the base station performs inverse rate matching on the combined coding information according to a rate matching mode adopted by the terminal, and performs channel decoding on the information obtained by inverse rate matching for the first time to obtain the receiving response information of the A bit and the CSI of the C bit.

Specifically, if the terminal adopts a block coding mode, the base station extracts coding information corresponding to each block in the joint coding information according to an information aggregation mode and an information block mode adopted by the terminal, respectively decodes the extracted coding information according to the coding mode adopted by the terminal, and restores the decoded information into a-bit reception response information and C-bit CSI information.

Specifically, the base station extracts the coding information corresponding to each group in the joint coding information according to an information aggregation mode and an information grouping mode adopted by the terminal, and the specific implementation can adopt the following three modes:

first, when the terminal does not perform rate matching in step 32:

and the base station extracts the coding information corresponding to each group in the combined coding information according to the information aggregation mode and the information grouping mode adopted by the terminal, and respectively decodes the extracted coding information according to the coding mode adopted by the terminal.
