Description

Uplink control information UCI sending and acquiring method and device

Technical Field

The invention relates to the field of communication, in particular to a method and a device for transmitting and acquiring uplink control information UCI.

Background

In the lte (long Term evolution) system, Uplink channels of a terminal include a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), and a Physical Random Access Channel (PRACH), where data Information, Hybrid Automatic Repeat request ACKnowledgement (HARQ-ACK) and Channel State Information (CSI) may be transmitted in the PUSCH, SR, HARQ-ACK, and CSI may be transmitted in the PUCCH, wherein, HARQ-ACK is a response message to a Physical Downlink Shared Channel (PDSCH) or a Physical Downlink Control Channel/Enhanced Physical Downlink Control Channel (PDCCH/EPDCCH) indicating Semi-Persistent Scheduling (SPS) release.

In order to meet the requirements of the International telecommunications Union-Advanced (ITU-Advanced for short), a Long Term Evolution-Advanced (Long Term Evolution-Advanced, LTE-a) system, which is an Evolution standard of LTE, needs to support a larger system bandwidth (up to 100MHz) and needs to be backward compatible with the existing standard of LTE. On the basis of the existing LTE system, the bandwidth of the LTE system can be combined to obtain larger bandwidth, the technology is called Carrier Aggregation (CA) technology, the technology can improve the spectrum utilization rate of the IMT-Advance system, relieve the shortage of spectrum resources and further optimize the utilization of the spectrum resources.

In a system in which Carrier aggregation is introduced, a Carrier to be aggregated is referred to as a Component Carrier (CC) or one Serving Cell (Serving Cell). Meanwhile, the concept of Primary Component Carrier/Cell (PCC/PCell) and Secondary Component Carrier/Cell (SCC/SCell) is also proposed, and in a system with Carrier aggregation, at least one Primary serving Cell and one Secondary serving Cell are included, where the Primary serving Cell is always in an active state.

In the existing carrier aggregation system, uplink control information comprises request scheduling SR, HARQ-ACK and periodic CSI, and when there is no PUSCH to transmit simultaneously, the control information can only be transmitted on the PUCCH of PCell. Meanwhile, the protocol defines a plurality of PUCCH formats to adapt to bear different uplink control information under different scenes. The plurality of PUCCH formats include:

PUCCH format 1: carrying the SR;

PUCCH format 1a/1 b: HARQ-ACK carrying 1/2 bits or HARQ-ACK and SR carrying 1/2 bits

PUCCH format 2a/2 b: HARQ-ACK carrying 1/2 bits and periodic CSI;

PUCCH format 2: carrying periodic CSI or carrying periodic CSI and HARQ-ACK;

PUCCH format 3: carrying HARQ-ACK, or carrying HARQ-ACK and SR, or carrying HARQ-ACK and CSI, or carrying HARQ-ACK, SR and CSI. The PUCCH format3 itself can carry 22 bits at most, while the existing protocol specifies that 20-bit HARQ-ACK or 20-bit HARQ-ACK and 1-bit SR can be carried at most, or 10-bit HARQ and 11-bit CSI and 1-bit SR.

Fig. 1 is a schematic diagram of a processing process when uplink control information is transmitted on a PUSCH (PUSCH corresponds to a single codeword stream), as shown in fig. 1, uplink data is transmitted in the form of a Transport Block (TB), the TB is subjected to cyclic redundancy check addition (CRC attachment), Code Block segmentation (Code Block segmentation) and sub-Block CRC addition (Code Block CRC attachment), Channel coding (Channel coding), Rate matching (Rate matching), Code Block synthesis (Code Block coordination), and then the encoded CQI/PMI is multiplexed with the uplink data and control signaling, and finally, the encoded ACK/NACK response information and RI information and data are multiplexed together by Channel interleaving. The coding process corresponding to the uplink control information is as follows:

firstly according to the formula (1)

Calculating the number Q 'of required code modulation symbols'_ACK、Q'_RI，

Calculating the number Q 'of the required code modulation symbols according to formula (2)'_CQI；

Wherein, O represents the number of bits of the transmitted uplink control information;

representing the bandwidth of the current subframe for PUSCH transmission, and representing the bandwidth by the number of carriers;

indicating the number of symbols used in the initial PUSCH transmission, except for a Demodulation Reference Signal (DMRS) and a Sounding Reference Signal (SRS);

the bandwidth during initial PUSCH transmission is represented by the number of subcarriers; c represents the number of code blocks corresponding to the transmission block after CRC and code block segmentation; k_rRepresenting the number of bits corresponding to each code block of the transport block; c, K for the same transport block_rAnd

obtaining from an initial PDCCH; when there is no PDCCH of the initial DCI format0,

c and K_rCan be obtained in two ways: (1) when the initial PUSCH adopts semi-persistent scheduling, the PUSCH can be acquired from the PDCCH configured by the latest semi-persistent scheduling; (2) when the PUSCH is triggered by the random access response authorization, acquiring the random access response authorization corresponding to the same transmission block;

to represent

Or

This value is configured by higher layers; l is the number of CRC check bits for CQI/PMI information when O_CQIWhen the value is more than 11, L is 8, otherwise L is 0; and then, carrying out channel coding according to a coding mode corresponding to the uplink control information, and repeating the bits after coding the ACK/NACK information, the RI information and the CQI/PMI information until Q is Q'. Q_mIn this way, according to the modulation order, a corresponding code modulation sequence is generated.

The determination of the current HARQ-ACK feedback sequence is determined based on configured parameters, specifically, for an aggregation system in which a primary serving cell is FDD, a terminal determines a HARQ-ACK sequence to be fed back according to the number of configured serving cells and a transmission mode configured by the serving cell, an uplink subframe to feed back HARQ-ACK, and a corresponding downlink serving cell forms a bundling window, fig. 2 is a schematic diagram of a HARQ-ACK bundling window in an aggregation system in which a primary serving cell is FDD in the related art, as shown in fig. 2, an HARQ-ACK of a downlink subframe 0 is to be sent on an uplink subframe 4, and the bundling window of FDD only includes the dimension of the number of serving cells. For an aggregation system with a TDD serving cell as a main serving cell, a terminal determines according to the number of configured serving cells, a transmission mode configured by the serving cell, and a downlink subframe of HARQ-ACK that needs to be fed back on the serving cell, an uplink subframe for feeding back HARQ-ACK, and a corresponding downlink serving cell and downlink subframe form a bundling window, fig. 3 is a schematic diagram of the HARQ-ACK bundling window in the aggregation system with the TDD serving cell in the related art, as shown in fig. 3, assuming that the uplink and downlink configurations of the TDD serving cell are the same and are both uplink and downlink configurations 2, then HARQ-ACKs of

downlink subframes

9,0,1, and 3 are sent on an uplink subframe 7, and the bundling window of TDD includes two dimensions, namely, the number of serving cells and the number of subframes.

In the TDD system, when HARQ-ACK needs to be transmitted on a PUSCH and the PUSCH transmitted by the HARQ-ACK has corresponding DCI format0/4, when a terminal calculates the number of coding modulation needed for transmitting the HARQ-ACK, the number of transmitted HARQ-ACK bits is determined according to DAI in DCI format0/4, the actual scheduling situation can be correctly reflected, the reasonable number of coding modulation is calculated, and the influence on data is reduced. Taking configuring PUCCH format3 to transmit HARQ-ACK as an example, the HARQ-ACK feedback sequence corresponding to serving cell c is

Wherein, when the transmission mode corresponding to the serving cell c supports 1 transport block or spatial domain HARQ-ACK binding enablement,

otherwise

The number of downlink subframes for feeding back HARQ-ACK bits is needed for a serving cell c; for TDD uplink and downlink configuration {1,2,3,4,6} and transmission of PUSCH is according to the detected DCI format0/4, then

The value is corresponding to the DAI field in DCI format 0/4.

Considering that the HARQ-ACK feedback sequence determination method is adopted in a situation that a large number of configured serving cells (corresponding to a scenario in which FDD is a main serving cell) or serving cells and subframes (corresponding to a scenario in which TDD is a main serving cell) are provided, and when the number of serving cells or serving cells and subframes requiring HARQ-ACK feedback is relatively small, a terminal will feed back a large amount of useless HARQ-ACK information. On one hand, the useless HARQ-ACK information affects the reception performance of the base station for the HARQ-ACK, and on the other hand, the terminal needs more transmission power and/or more uplink resources to transmit the HARQ-ACK. Therefore, determining the HARQ-ACK sequence according to the scheduling cell is a subsequent enhancement scheme, wherein in order to solve the problem of inconsistent understanding of the eNB and the UE on the HARQ-ACK feedback sequence, a second DAI design of the DAI domain in the PDCCH/EPDCCH corresponding to the PDSCH is introduced, for example, the second DAI is a serving cell DAI and a subframe DAI, and is different from the existing first DAI. The HARQ-ACK sequence which needs to be transmitted actually can be determined through the introduced second DAI scheme, so when the HARQ-ACK is transmitted on the PUSCH and the number of the coding modulation symbols needed by the HARQ-ACK is calculated, the determination can be carried out according to the length of the HARQ-ACK sequence, and the determination through the DAI domain in the DCI format0/4 is not needed.

In the related art, an effective solution is not provided at present for the problem that downlink resources cannot be effectively utilized in the process of processing uplink control information.
