Description

Method and device for transmitting channel state information

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a method and apparatus for transmitting channel state information. In the Long Term Evolution (LTE), the control information that needs to be sent in the uplink has ACK/NACK (Acknowledgement/Negative Acknowledgement) and channel state information (CSI, which reflects the state of the downlink physical channel). Channel State Information), wherein the channel state information includes the following: a channel quality indicator (CQI, Channels quality indication), a pre-coding matrix indicator (PMI), and a rank indicator (RI, Rank Indicator). In the LTE system, the ACK/NACK response message is on the physical uplink control channel (PUCCH, Physical Uplink).

The control is sent in the format l/la/lb (PUCCH formatl/lal/b). If the terminal (UE, User Equipment) needs to send uplink data, it is sent on the physical uplink shared channel (PUSCH, Physical Uplink Shared Channel). The reported CSI may be periodic or non-periodic. The specific feedback is shown in Table 1. Table 1 Uplink physical channels corresponding to periodic and aperiodic reporting

If the UE does not need to send the uplink data, the periodically reported CSI is sent on the PUCCH in the format 2/2a/2b (PUCCH format 2/2a/2b). If the UE needs to send the uplink data, the periodically reported CSI is on the PUSCH. The upper CSI is sent only on the PUSCH. High-level signaling semi-static configuration The UE periodically reports different CQI, PMI, and RI information on the PUCCH. The reporting mode used for reporting is as shown in Table 2. Each downlink transmission mode has a corresponding reporting mode. Table 2. Periodic reporting mode

PMI feedback type

No feedback PMI single PMI

CQI Anti-Broadband (Broadband CQI) Mode 1-0 Mode 1-1

Feed Type UE Selected (Subband CQI) Mode 2-0 Mode 2-1 The LTE defines the CQI/PMI information and the RI information reporting type, that is, the reporting type 1 that supports the UE to select the sub-band CQI information feedback, the reporting type 2 that supports the broadband CQI information and the PMI information feedback, and the reporting type that supports the RI information feedback. 3. Supports reporting type 4 of broadband CQI information.

The LTE system further specifies a process of transmitting uplink control information on the PUSCH, first calculating a target length of the uplink control information to be transmitted, and then performing channel coding, and the ACK/NACK response information and the RI information are encoded in the same manner, when CQI/PMI When the number of bits of the information is less than or equal to 11 bits, the encoding is performed by the encoding method of (32, 0); otherwise, the CRC is added first, and then the biting tail having a length of 7 and a code rate of 1/3 as shown in FIG. 1 is used. The encoding method of the product code is encoded, and finally the bits encoded by the ACK/NACK response information, the RI information, and the CQI/PMI information are repeated until the target length is satisfied, and the encoded information bits are respectively recorded as n ^ACK n ^ACK n ^ACK 1 A° ^QI a° ^QI a° ^QI a ^CQI 1 Γ" ⁵⁷ n ^m n ^m n ^m 1 Uplink data information and control information are multiplexed, that is, the encoded CQI/PMI information and data information are in the form of modulation symbols. Linked together, it is recorded as ^[ ''''''' ^^1 ^] . Then channel interleaving: The encoded ACK/NACK response information bit sequence, ^^,^,...,^^ ¹ ] , RI information bit sequence...' ^^:! and the bit sequence [^ '^ '^ '''''^ ] which is multiplexed by data and control is written into a virtual matrix, and then the virtual matrix is read out in the order of the preceding and following columns, thereby ensuring In the process of subsequent modulation symbol to physical resource mapping, ACK/NACK response information, RI information, CQI/PMI information and data information can be mapped to the positions shown in Figure 2, respectively. To satisfy the Advanced International Telecommunication Union (ITU) -Advanced, International Telecommunication Union-Advanced), the LTE-Advanced Long Term Evolution Advanced (LTE-A) system needs to support larger system bandwidth (up to 100MHz) and requires backward compatibility. LTE existing standards. Based on the existing LTE system, the bandwidth of the LTE system can be combined to obtain a larger bandwidth. This technology is called Carrier Aggregation (CA) technology. The spectrum utilization of the advanced international mobile communication (IMT-Advance) system, mitigating the shortage of spectrum resources, and optimizing the utilization of spectrum resources. The LTE system bandwidth of the carrier aggregation can be regarded as a component carrier (CC). Each component carrier can also be called a serving cell, that is, one spectrum can be composed of n component carriers (or serving cells). Aggregated. An R10 user device

The resources of the UE (User Equipment) are composed of n component carriers (or serving cells) in the frequency domain, where one serving cell is called a primary cell (or primary cell), and the remaining serving cells are called secondary cells. (or secondary component carrier) (Secondary cell). In the LTE-A system, the CQI/PMI information and the reporting type of the RI information are also extended to: support the UE to select the sub-band CQI information reporting type 1, support the sub-band CQI and the second PMI feedback reporting type la, and support the broadband CQI. Report type 2 of the information and PMI information feedback, report type 2b, Report type 2c, report type 2a that supports wideband PMI feedback, report type 3 that supports RI information feedback, report type 4 that supports wideband CQI information, report type 5 that supports RI and wideband PMI feedback, and support for RI and PTI (Precoder Type Indication) ) Report type 6.

The LTE-A system provides: If the UE is configured with multiple downlink serving cells, the UE sends only one periodic CSI information of the downlink serving cell in any subframe, that is, the periodic CSI reports of multiple serving cells are sent in a time division multiplexing manner. . The related art also specifies a processing manner in which the periodic CSI information of multiple serving cells needs to be transmitted in the same subframe: Selecting a periodic CSI information transmission corresponding to one downlink serving cell, and erasing the periodic CSI information corresponding to other downlink service cells. The specific selection method is: according to the priority selection of the periodic CSI reporting type of each downlink serving cell, that is, the periodic CSI information of the serving cell with the higher priority of the reporting type is selected, if the periodic CSI information corresponding to the multiple downlink serving cells The reporting type has the same priority, and is selected according to the serving cell index value, that is, the periodic CSI information of the serving cell with the smallest serving cell index value is selected. The report type of the highest priority is: report type 3, report type 5, report type 6 and report type 2a; the report type with the lowest priority is: report type 1 and report type la; the priority of other report types is between.

In the LTE-A system, the periodic CSI of multiple downlink serving cells is not supported, but the periodic CSI of multiple downlink serving cells is transmitted in a time division multiplexing manner. Therefore, the base station obtains the channel quality information delay of each downlink serving cell. Scheduling has an impact, which affects the throughput of the system. In addition, the periodic CSI of multiple downlink serving cells needs to be transmitted in multiple uplink subframes, which wastes uplink resources, and the time-division multiplexing method cannot completely avoid the periodic CSI information of multiple downlink serving cells simultaneously, when multiple downlinks are used. When the periodic CSI of the serving cell needs to be transmitted simultaneously, only one periodic CSI report of the downlink serving cell is sent, and the periodic CSI report of other downlink serving cells is cancelled, which may also degrade the performance of the system, and in subsequent versions, due to the new technology The introduction of the Coordinated Multi-Point Transmission and Reception (CoMP, Coordinated Multi-Point Transmission and Reception) also increases the number of periodic CSIs to be transmitted. Each channel state information reference signal (CSI-RS, Channel State Information-Reference signal) The resource corresponds to one cycle of CSI. Different CSI-RS resources may correspond to different base stations, or may correspond to different transmission nodes, and delaying or knocking down the impact on the system cannot be ignored. During the discussion of LTE-A, it is proposed to introduce several large-load PUCCH formats to support periodic CSI transmission, such as the current PUCCH format 3, or PUSCH. However, the transmission method of transmitting multiple serving cell cycle CSIs using the PUSCH is not given, and in the related art, sufficient PUSCH resources are not configured for the terminal, and therefore, the terminal cannot implement multiple serving cells and/or CSI-RS resources. The CSI transmits a CSI-RS resource CSI-RS resource on the PUSCH.
