Description

Method and device for sending uplink control information

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for sending uplink control information.

Background

A Long Term Evolution (Long Term Evolution, LTE for short) system is an important project of the third generation partnership organization, fig. 1 shows a structural diagram of a basic frame structure in the LTE system, and as shown in fig. 1, the frame structure is divided into four levels of a radio frame, a field, a subframe, and a slot, wherein a length of one radio frame is 10ms, one radio frame is composed of two fields with a length of 5ms, one field is composed of 5 subframes with a length of 1ms, and one subframe is composed of two slots with a length of 0.5 ms.

In the Downlink HARQ of LTE, an Acknowledgement/Negative Acknowledgement (ACK/NACK) response message of a Physical Downlink Shared Channel (PDSCH) is transmitted on a Physical Uplink Control Channel (PUCCH) when a terminal (User Equipment, UE) does not have the Physical Uplink Shared Channel (PUSCH). LTE defines various PUCCH formats, including PUCCH formats 1/1a/1b and format2/2a/2b, where format1 is used to send a Scheduling Request (SR) signal of a UE, formats 1a and 1b are used to feed back 1-bit ACK/NACK response Information and 2-bit ACK/NACK response Information, respectively, and format2 is used to send Channel State Information (CSI).

In an LTE system, in a Frequency Division Duplex (FDD) system, since uplink and downlink subframes are in one-to-one correspondence, when a PDSCH includes only one transport block, a UE needs to feed back 1-bit ACK/NACK response information, and when the PDSCH includes two transport blocks, the UE needs to feed back 2-bit ACK/NACK response information, and the UE uses PUCCH format/1 b to send 1/2-bit ACK/NACK response information. In a Time Division Duplex (TDD) system, because uplink and downlink subframes are not in one-to-one correspondence, that is, ACK/NACK response information corresponding to a plurality of downlink subframes needs to be sent on a PUCCH channel of an uplink subframe, wherein a downlink subframe set corresponding to an uplink subframe constitutes a "bundling window". There are two methods for sending ACK/NACK response information: one is bundling, and the core idea of the method is to perform logical and operation on ACK/NACK response information of a transport block corresponding to each downlink subframe that needs to be fed back on the uplink subframe. If one downlink subframe has 2 transmission blocks, the UE needs to feed back 2-bit ACK/NACK response information, if one downlink subframe has only one transmission block, the UE needs to feed back 1-bit ACK/NACK response information, and the UE adopts PUCCH format 1a/1b to send 1/2-bit ACK/NACK response information; the other method is a Multiplexing with Channel Selection method, the core idea of the method is to use different PUCCH channels and different modulation symbols on the PUCCH channels to represent different feedback states of a downlink subframe that needs to be fed back on the uplink subframe, if there are multiple transport blocks on the downlink subframe, perform logical and (Spatial Bundling) on ACK/NACK fed back by the multiple transport blocks of the downlink subframe before performing Channel Selection, and the UE uses format1b with Channel Selection (format1b joint Channel Selection) to send an ACK/NACK response message.

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 order to obtain higher peak spectrum efficiency, in an LTE-a system, multiple transmission antennas are supported in uplink, that is, the uplink supports a single-antenna transmission mode and a multi-antenna transmission mode. Considering that the transmission diversity mode can improve the reliability of channel transmission and improve the signal-to-noise ratio of received signals, the discussion of the multi-antenna transmission mode for the PUCCH channel is based on the transmission diversity mode, and for the four-antenna scenario, the multi-antenna transmission mode is obtained by virtualizing two antennas.

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. For a terminal of LTE-A, if the terminal supports 4-bit ACK/NACK response information at most, using format1b with channel selection to send the ACK/NACK response information; if the ACK/NACK response information with more than 4 bits is supported, the ACK/NACK response information can be sent by using format1b with channel selection, the ACK/NACK response information can also be sent by using a newly introduced PUCCH format3, and the ACK/NACK response information is specifically configured by using which mode is used for sending the ACK/NACK response information through high-level signaling.

Space Orthogonal Resource Transmission Diversity (SORTD) is a transmission Diversity scheme of PUCCH format/1 a/1b, format2/2a/2b and format3 under the current multi-antenna system, the principle of SORTD is to use different Orthogonal resources to Transmit the same signaling on different antennas, and for channel selection, the number of the used Orthogonal resources is multiplied, so the same signaling is not supported to be transmitted on different antennas in the Rel-10 version. In subsequent releases, for FDD systems, 4 PUCCH resources are used at most for transmission in the multi-antenna mode, and for TDD systems, the problem of channel selection for transmission in the multi-antenna mode is not yet achieved.

In view of the above problems, no effective solution has been proposed.

when the PDCCH corresponding to the PDSCH of the secondary cell is in the primary cell, the transmission diversity scheme is the SORTD with the PUCCH resource number of 8;

when the PDCCH corresponding to the PDSCH of the secondary cell is not in the primary cell and the number of downlink subframes corresponding to the uplink subframes is 2, the transmission diversity scheme is a SORTD with the number of PUCCH resources being 8;

and when the PDCCH corresponding to the PDSCH of the secondary cell is not in the primary cell and the number of downlink subframes corresponding to the uplink subframes is more than 2, the transmission diversity scheme is an improved SORTD with the PUCCH resource number of 6.

12. An apparatus for transmitting uplink control information, wherein the apparatus for transmitting uplink control information is located on a UE in a time division duplex system, comprising:

the selection unit is used for selecting a transmission diversity scheme according to the number of configured service cells and the number of downlink subframes corresponding to uplink subframes where the physical uplink control channel PUCCH is located when the physical uplink control channel PUCCH transmission mode is configured into a multi-antenna transmission mode and is configured to adopt a format1b joint channel to select and feed back correct/error response information;

and a sending unit, configured to send uplink control information according to the selected transmission diversity scheme.
