Description

Information transmission method, device and system

Technical field

The present invention relates to the field of communications, and in particular, to an information transmission method, device, and system.

Background technique

CA (Carrier Aggregation) is a key technology in the LTE (Long Term Evolution) system. It can aggregate multiple LTE component carriers (CCs) to achieve higher bandwidth information transmission. .

However, when more than 5 carriers are aggregated by using the CA technology, each sub-frame needs to transmit more information, so the amount of information is greatly increased. For example, in a CA scenario, the PUCCH (Physical Uplink Control Channel) is used. The UCI (Uplink Control Information) is fed back, and the UCI information of the multiple CCs can be fed back in each subframe. In the prior art, the UCI information includes only UCI information of up to 5 carriers, and the occupied PUCCH resource is 1 PRB. (Physical Resource Block), only the location of the PRB is indicated. When the amount of UCI information that is fed back is too large, for example, when there are more than 5 carriers, the PUCCH resource occupied by the UCI information may exceed one PRB, which may cause the PUCCH resource information to be uninformed.

Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (General Packet Radio Service, GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (Universal Mobile Telecommunication System, UMTS) or Worldwide Interoperability for Microwave Access (WiMAX) communication system.

It should be understood that, in the embodiment of the present invention, the first device or the second device includes but is not limited to a user equipment (English name: User Equipment, English abbreviation: UE), and a mobile station (English full name: Mobile Station, English abbreviation: MS) Mobile terminal, mobile telephone, handset, and portable equipment.

In the embodiment of the present invention, the first device or the second device may be a base station in GSM or CDMA (English full name: Base Transceiver Station, English abbreviation: BTS), or may be a base station (NodeB) in WCDMA, or may be LTE. The embodiment of the present invention is not limited to the evolved base station (English name: evolved Node B, English abbreviation: eNB or e-NodeB).

It should be understood that, in the embodiment of the present invention, the “first” and the “second” are used for distinguishing, and are not used for limitation in the embodiment of the present invention. Preferably, in the present invention, the first device is a user equipment. The second device is a base station. Of course, the description herein is merely illustrative and does not mean that the present invention is limited thereto.

The embodiment of the present invention provides an information transmission method, which is applied to a first device. Preferably, the first device is a user equipment. Referring to FIG. 1 , the information transmission method includes the following steps:

101. The first device determines a PUCCH format used to send the UCI.

The size of the load information corresponding to the PUCCH format is greater than or equal to the information size of the UCI. Here, it should be noted that the information size of the UCI refers to the UCI before encoding. The size of the information, the size of the payload information corresponding to the PUCCH format is also the size of information that can be carried before encoding in the PUCCH format. Preferably, the information size of the UCI refers to the number of bits of the UCI before encoding.

The PUCCH format can be defined differently. 1) In the first definition, the PUCCH format includes the resource size of the PUCCH, that is, each PUCCH format has a fixed PUCCH resource size, that is, the number of occupied PRB (Psical Resource Block) pairs, and is fixed. The length of the encoded information, and the total number of symbols. For example, in PUCCH format 3, the PUCCH resource size is fixed to 1 PRB pair (PRB pair), and the encoded information size is 48 bits, and the total number of symbols occupied by the load information is 24 modulation symbols. 2) In the second definition manner, the PUCCH format does not include the resource size of the PUCCH, and the PUCCH format having the same number of modulation symbols and user multiplexing degree on a unit resource (ie, a single PRB pair) may be referred to as the same PUCCH. format. The same PUCCH format can occupy different PUCCH resource sizes (that is, the number of PRB pairs, and no special statement is made later, and the number of PRBs refers to the number of PRB pairs), and different modulation modes can be used to generate different numbers. The encoded information bits.

It should be noted that the PUCCH in the LTE system is used by the UE to send uplink L1/L2 (layer 1/layer 2) control information, and is used to support uplink and downlink data transmission. The uplink L1/L2 control information (UCI) may include:

The SR (Scheduling Request) is used to request an Uplink Physical Uplink Shared Channel (ULSCH) resource from the base station;

HARQ (Hybrid Automatic Repeat Request) ACK/NACK (Acknowledgment/Negative Response), which is called HARQ feedback information, is used to transmit downlinks on the PDSCH (Physical Downlink Shared Channel). Data is HARQ confirmed;

CSI (Channel State Information) includes information such as CQI (Channel Quality Indicator), PMI (Precoding Matrix Indicator), and RI (rank indication). It is used to indicate the downlink channel quality and the like, so that the base station performs downlink scheduling.

The UCI information in the present invention may include any one of the above information or a plurality of types of information. Combinations, of course, are merely illustrative and are not meant to limit the invention. .

The existing PUCCH format PF3 (PUCCH Format 3, physical uplink control channel format 3) can encode up to 22 bits of information, occupying 1 PRB. When CA technology is used to make the UCI information volume too large, there is no way. transmission. Therefore, it is necessary to select a new PUCCH format for transmission. The present application provides a method for transmitting UCI information on a PUCCH based on a plurality of new PUCCH formats, considering different PUCCH format definition manners.

Here, optionally, the three PUCCH format types provided in this embodiment are described as follows:

The first PUCCH format:

Based on the structure of the existing PUSCH (Physical Uplink Shared Channel), the following changes are made: 1) In addition to DMRS (De Modulation Reference Signal), it can be used to transmit UCI; 2) UCI The coding method adopts TBCC (Tail Biting Convolutional Coding); 3) increases the number of DMRS symbols; 4) specifies the resource mapping position of various UCI information.

For the case where the occupied resource is 1 PRB, the maximum number of encoded symbols that can be carried in the first PUCCH format is 144 modulation symbols, and if it is QPSK (Quadrature Phase Shift Keying) modulation, then support The number of coded bits is 144×2=288 bits. When the coding rate is between 0.1 and 0.9, the UCI information size supported by the PUCCH format ranges from 22 to 256 bits, and the preferred range is from 64 to 256 bits. For higher order modulation, or more PRBs, the UCI information it supports can be larger.

The second PUCCH format:

The existing PUCCH format 3 format is improved: 1) the number of PRBs is more than one PRB; 2) the modulation mode; 3) the coding mode is TBCC.

For the case of 1-PRB, the maximum number of coded symbols that can be carried in the second PUCCH format is 24 modulation symbols. If it is QPSK modulation, the number of supported bits is 24×2=48 bits, in the case of bit rate change. Next, the second PUCCH format supports The UCI information size is between 22 and 64 bits.

The third PUCCH format:

Reduce the number of DMRSs to 1 and reduce the number of OCC (Orthogonal Convolutional Codes) based on the existing PF3 format. When the number of OCCs is reduced from the original 5 to 2. The maximum number of encoded symbols supported by it is 144 modulation symbols.

Specifically, as shown in Table 1, the specific PUCCH format is as follows:

Table I

Among them, DMRS (De Modulation Reference Signal). This embodiment provides two definitions of the PUCCH format, which corresponds to the case where the PUCCH format includes the PUCCH resource size and the PUCCH format does not include the PUCCH resource size, as shown in Table 2 and Table 3.

Table II

	第一格式First format	第二格式Second format	第三格式Third format
每个资源块上DMRS个数Number of DMRS per resource block	11	22	11
正交序列个数Orthogonal sequence number	11	55	22
单位资源上的调制符号数Number of modulation symbols on a unit resource	144144	24twenty four	7272

调制方式Modulation	QPSKQPSK	QPSKQPSK	QPSKQPSK
编码后比特数Number of bits after encoding	288288	9696	144144

Optionally, as shown in Table 2, the first definition of the PUCCH format can be applied. The PUCCH format does not include the resource size of the PUCCH. In the same PUCCH format, different coding methods may be used according to different UCI information sizes, and the coding rate may be different. Here, an encoding rate of 0.5 is used as an example to estimate the UCI information size that can be carried in different PUCCH formats. The size of the UCI information that can be carried by the first format is 144; the size of the UCI information that can be carried by the second format is 48; and the size of the UCI information that can be carried by the third format is 72.

Table 3

Optionally, as shown in Table 3, the second definition manner of the PUCCH format may be applied, that is, the PUCCH format does not include the resource size of the PUCCH. Of course, the description herein is merely illustrative and does not mean that the present invention is limited thereto.

The modulation method includes QPSK (Quadrature Phase Shift Keyin), QAM (Quadrature Amplitude Modulation) 16QAM, 32QAM, and the like.

For the first device, how to determine the PUCCH format, this embodiment provides two specific implementation manners. Of course, the description herein is merely illustrative and does not mean that the present invention is limited to this:

The first implementation,

Optionally, before step 101, the first device may receive the second The second indication information is used to indicate a PUCCH format, and the first device determines the PUCCH format according to the second indication information.

Optionally, the second indication information is sent to the first device by using DCI (Downlink Control Information) or RRC (Radio Resource Control) signaling, when the second indication information is carried on the DCI. The second indication information is included in the original field of the DCI, or the second indication information is included in the newly added field of the DCI. Optionally, the format of the DCI is DCI format 0/1/1A/1B/1C/1D/2/2A/2B/2C/2D/4, or the format of the DCI is DCI format 5. The DCI format 5 refers to a new DCI format without special explanation below. In this case, the second device indicates the information such as the PUCCH format of the second device by using the display mode. In this case, the first device may not store the correspondence between the information size of the UCI and the PUCCH format, and the second device indicates.

In the first implementation manner, the second device indicates the PUCCH format and other information to the first device. Optionally, the first implementation manner may be applied to two preferred application scenarios, in one application scenario. The Codebook Size of the HARQ-ACK when the number of carriers is configured to be the largest is used. Or, in another application scenario, the UCI information size changes dynamically and is configured in real time. Of course, the following is only three application scenarios for illustration, and does not mean that the present invention is limited thereto.

The second implementation,

Optionally, before step 101, the first device acquires the information size of the UCI; the first device determines the PUCCH format according to the correspondence between the predefined information size and the PUCCH format and the information size of the UCI. Optionally, the information size of the UCI includes at least one of a size of the HARQ feedback information, an information size of the CSI, and an information size of the SR. Further, when the first device determines, in the preset list that has been stored, that the information size of the UCI is less than or equal to the information size corresponding to the nth PUCCH format of the N PUCCH formats included in the preset list, the nth The PUCCH format serves as a PUCCH format for transmitting the UCI. In this case, both the first device and the second device need to store the correspondence between the information size of the UCI and the PUCCH format, and there is no need to display the information by sending the information.

In the second implementation manner, the second device indicates the PUCCH format and other information, that is, the information indication is not sent, but the first device and the second device pre-set the UCI information size and the PUCCH format. Corresponding relationship, optionally, the second implementation manner can be applied to a preferred application scenario. The information size of the UCI (Information Size & Codebook Size) can determine the UCI information size according to the number of carriers and the transmission mode configured in the CA scenario. The information size may be a Codebook Size of a HARQ-ACK (Hybrid Automatic Repeat ReQuest-Acknowledgement). Table 4 gives an example of the PUCCH format by the HARQ codebook size:

Table 4

1～21比特1 to 21 bits	PUCCH format3PUCCH format3
22～64比特22 to 64 bits	Multi-PRB PF3(第二种PUCCH格式)Multi-PRB PF3 (second PUCCH format)
65～128比特65 to 128 bits	PUSCH-based format(第一种PUCCH格式)PUSCH-based format (first PUCCH format)

102. The first device sends a UCI to the second device by using a PUCCH format.

Optionally, in the two definition manners of the PUCCH format, when the PUCCH format includes the resource size of the PUCCH, the first device sends the UCI to the second device according to the resource size of the PUCCH corresponding to the PUCCH format; and the PUCCH format does not include the PUCCH resource. The large device determines the resource size of the PUCCH, and sends the UCI to the second device according to the PUCCH format and the resource size of the PUCCH.

Optionally, for the case that the PUCCH format does not include the resource size of the PUCCH, the first device may acquire the information size of the UCI, and determine the resource size of the PUCCH according to the correspondence between the size of the UCI information and the resource size and the information size of the UCI; or The first device receives the first indication information, where the first indication information is used to indicate the resource size of the PUCCH, and the first device determines the resource size of the PUCCH according to the first indication information. Further, the first indication information may be sent to the first device on the DCI or the RRC signaling. When the first indication information is carried on the DCI, the first indication information is included in the original field of the DCI, or The first indication information is included in the new field of the DCI. Among them, optional, DCI format is DCI format 0/1/1A/1B/1C/1D/2/2A/2B/2C/2D/4, or DCI format is DCI format 5.

In addition, optionally, the first device may also determine a resource start location of the PUCCH, and the first device may adopt a PUCCH format, and send the UCI to the second device according to the resource start location of the PUCCH. Optionally, the first device may receive the third indication information that is sent by the second device, where the third indication information is used to indicate a resource start location of the PUCCH, and the first device determines a resource start location of the PUCCH according to the third indication information. Optionally, the third indication information is sent to the first device on the downlink control information DCI, where the third indication information is included in the original field of the DCI, or the first indication information is included in the newly added field of the DCI. Optionally, the DCI format is DCI format 0/1/1A/1B/1C/1D/2/2A/2B/2C/2D/4, or the format of the DCI is DCI format 5. Certainly, the foregoing is only an example. The third indication information may also be sent in the RRC signaling or other information, which is not limited in this embodiment.

Optionally, when the UCI information includes CSI information of multiple CCs, or CSI information and HARQ feedback information of multiple CCs, the second device may instruct the first device to send UCI information of different sizes according to different uplink channel conditions. The second device provides MCS index information to the first device, by which the first device can correspondingly know the modulation mode and/or the redundancy version of the PUCCH. And the size of the UCI information that can be transmitted is obtained by the first device by using the corresponding TBS table of the MCS index. Low-priority CSI information that exceeds the UCI information size can be discarded. The first device may encode the UCI according to a modulation mode and an encoding policy corresponding to the PUCCH format, and send the encoded UCI.

Optionally, this embodiment provides a specific MCS (Modulation and Coding Scheme) indication table as shown in Table 5. The specific TBS table is also shown in Table 6.

Table 6

Optionally, before the step 102, the first device may receive the DCI information sent by the second device, where the DCI information is used to indicate at least one of a modulation mode corresponding to the PUCCH format and an encoding policy corresponding to the PUCCH format.

It should be noted that the first indication information, the second indication information, and the third indication information may be sent simultaneously, or may be separately sent. Preferably, the first indication information, the second indication information, and the third indication information may be included in the first The DCI sent by the two devices is sent to the first device. Of course, it can also be carried in other information (such as RRC signaling). This is only an example. Optionally, the second indication information and the third indication information may be represented by a domain, that is, the size of the resource and the starting address of the resource are simultaneously calculated by using one value. Further, the first indication information and the second indication information may use the original DCI format to redefine the field of the original DCI information to indicate information, for example, TPC (Transmit power control) of the DCI information. The control field is used to indicate the PUCCH format, and of course, this is merely an example, and does not mean that the present invention is limited thereto. Alternatively, the first indication information, the second indication information, and the third indication information may adopt a new DCI format, and may perform field division on the DCI to indicate a field indicating the information division, for example, all the bits of the DCI. It is divided into a PUCCH format field, a resource start position field, a resource size field, an MCS field, a TBS field, and the like. Table 7 illustrates a new DCI format (DCI format 5):

Table 7

In order to reduce the number of blind checks, the new DCI format can use the same size as the existing DCI format 0.

Optionally, for the implementation of the original DCI format, the original DCI information field is redefined. This embodiment provides a specific definition manner as shown in Table 8. The original DCI is reused. The format of format 0, the new settings are shown in the last column of the table:

Table eight

The transmit power control field of the scheduled PUSCH may be used to indicate a PUCCH format. It should be noted that when the original DCI is used to perform the PUCCH information indication, a new RNTI (Radio Network Temporary Identifier), that is, a radio network temporary identifier, may be introduced to XOR the DCI data, and the new RNTI may be referred to as a PUCCH-RNTI. And the length of the new DCI format remains the same as the original DCI format0 and format1A.

In the information transmission method provided by the embodiment, the first device determines the PUCCH format for transmitting the UCI, and sends the UCI to the second device by using the PUCCH format, where the information size corresponding to the PUCCH format is greater than or equal to the information size of the UCI, because UCI information size selects an appropriate PUCCH format to encode and transmit UCI, and the new PUCCH format provided in this embodiment supports encoding and sending of a large amount of information.
