Problems solved by technology

[0013] Considering that in subsequent versions, the carrier aggregation technology that supports up to 32 serving cells results in the number of HARQ-ACK bits that need to be sent far exceeding 10 / 20 bits, the existing PUCCH format 3 will not be able to carry
[0014] For the problem of the small number of bits of the uplink control information carried by the PUCCH format in the related art, no effective solution has been proposed yet

Embodiment 1

[0176] like Figure 18 As shown, a preprocessing process of uplink control information in a preferred embodiment of the present invention is given, the figure is Figure 5 or Image 6a form of deformation. In this example, the preprocessing process of the preferred embodiment of the present invention includes: source bit segmentation, channel coding, concatenation, scrambling, modulation, time domain extension or repetition, transmission pre-transformation, resource mapping, etc.

[0177] Wherein, the process of scrambling and transmission pre-conversion can refer to the corresponding process of PUCCH format 3 in the existing LTE standard, and will not be repeated in the preferred embodiment of the present invention.

[0178] Wherein, the channel coding may consist of P block codes, where P is an integer greater than 2.

[0179] Preferably, P is determined according to one of the following methods:

[0180] Mode 1: Determine the maximum number of bits of uplink control inf...

Embodiment 2

[0184] When the number P of block codes for channel coding is determined according to the maximum number of bits of uplink control information that the system needs to feed back, the number of block codes can be determined in the following two ways:

[0185] Mode 1a: determined according to the maximum number of bits of the HARQ-ACK that need to be fed back in the FDD and TDD systems respectively.

[0186] where, for FDD, the required 64 is equal to 32×2, that is, 32 FDD serving cells are aggregated, and each serving cell is configured with a transmission mode scenario of 2 transport blocks. This scenario is required for the FDD system to support 32 carrier aggregation The scene with the most HARQ-ACK feedback.

[0187] And for TDD, need 128 is equal to 32×4, that is, 32 TDD serving cells are aggregated, and each serving cell needs to feed back the HARQ-ACK of 4 downlink subframes according to the downlink reference configuration.

[0188] When the value of P is determine...

Embodiment 3

[0193] An encoder using 6 block codes and a new PUCCH format 4 using 6 OFDM symbols to carry uplink control information are used as an example for illustration.

[0194] Assume that the physical uplink control channel carrying uplink control information adopts the following Figure 19 In the reference signal structure shown, the third OFDM symbol of each time slot (that is, the No. 3 OFDM symbol mentioned above, similar descriptions in the embodiments of the present invention are explained with reference to this definition) is used to carry reference signal, and other OFDM symbols are used to carry uplink control information. OFDM symbols in each slot are numbered starting from 0, the same below.

[0195] Under this structure, the number of resource block units that can carry uplink control information is 12×12=144. Assuming that QPSK modulation is used, a total of 288 coded bits can be carried.

[0196] The block coder can adopt the (32, O) block code supported by the exist...

Abstract

The invention provides an uplink control information transmitting method, an uplink control information transmitting device and user equipment. The method comprises the steps of preprocessing the uplink control information; and transmitting the uplink control information on a physical uplink control channel carrying the uplink control information. According to the method, the problem that in related technologies, the uplink control information carried by a PUCCH format is small in bit number is solved, and thus the bit number of the uplink control information can be carried by the physical uplink control channel is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method, device and user equipment for sending uplink control information. Background technique [0002] In the Long Term Evolution (LTE for short) system, the uplink channel of the terminal includes a Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH for short), a Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH for short) and Physical Random Access Channel (Physical Ramdom Access Channel, PRACH for short). Among them, data information, scheduling request (Scheduling Request, SR for short), Hybrid Automatic Repeat request ACKnowledgment (HARQ-ACK for short), and channel state information (Channel State Information, CSI for short) can be transmitted in the PUSCH. , SR, HARQ-ACK and CSI can be transmitted in the PUCCH. [0003] In order to meet the requirements of the International Telecommunication Union-Advanced (ITU-Advanced for s...
