Problems solved by technology

[0011] In the prior art, PUCCH format3 supports HARQ-ACK transmission of up to 10 / 20 bits. Considering that in subsequent versions, the carrier aggregation technology that may support more than 5 serving cells results in the number of HARQ-ACK bits to be sent far exceeding 20 bits. Therefore, it cannot be sent using PUCCH format3
[0012] At present, there is no relevant technology for transmitting uplink control information during carrier aggregation of more than 5 serving cells for reference

Embodiment 1

[0071] The UE determines the binding mode at least according to the number of aggregated serving cells, and obtains the HARQ-ACK information to be sent according to the determined binding mode;

[0072] The HARQ-ACK information is sent by using the PUCCH.

Embodiment 2

[0074] In this embodiment, it is assumed that the UE uses PUCCH format3 to send HARQ-ACK information, and it is assumed that the maximum value of HARQ-ACK information carried by PUCCH format3 is 10, that is, the PUCCH capacity is 10;

example 1

[0076] Assuming that the number of aggregated serving cells is 6, because the number of aggregated serving cells is less than or equal to 10, use method 2 to obtain the HARQ-ACK information to be sent:

[0077] When each serving cell corresponds to a codeword stream, the HARQ-ACK information to be sent is {HARQ-ACK(0), HARQ-ACK(1), HARQ-ACK(2),..., HARQ-ACK(5)}, as shown in Figure 4(a);

[0078] When each serving cell corresponds to two codeword streams, the HARQ-ACK information to be sent is the space-bound HARQ-ACK information {HARQ-ACK(0), HARQ-ACK(1), HARQ-ACK(2 ),..., HARQ-ACK(5)}, as shown in Figure 4(b).

[0079] The HARQ-ACK information is sent using PUCCH format3 (single RM: Reed-Muller).

Abstract

The embodiment of the invention discloses an uplink control information transmission method and device. The method comprises the steps that when K service cells are polymerized, user equipment UE determines a binding mode of hybrid automatic retransmission acknowledgement HARQ-ACK information at least depending on the number of polymerized service cells, acquires hybrid automatic retransmission acknowledgement HARQ-ACK information to be sent according to the binding mode and sends the HARQ-ACK information on a physical uplink control channel PUCCH, wherein K is a positive integer greater than zero.

Description

technical field [0001] The present invention relates to a transmission technology of uplink control information, in particular to a transmission method and device for uplink control information applied in a carrier aggregation system. Background technique [0002] The radio frame in the Long Term Evolution (LTE, Long Term Evolution) system and the Long Term Evolution Advanced (LTE-A, LTE-Advanced) system includes a Frequency Division Duplex (FDD, Frequency Division Duplex) mode and a Time Division Duplex (TDD) mode. , Time Division Duplex) mode frame structure. figure 1 It is a schematic diagram of the frame structure in the existing LTE / LTE-A FDD system, such as figure 1 As shown, a wireless frame of 10 milliseconds (ms) consists of twenty slots (slots) with a length of 0.5ms and numbers 0 to 19, and slots 2i and 2i+1 form a subframe (subframe) with a length of 1ms i. figure 2 It is a schematic diagram of the frame structure in the existing LTE / LTE-A TDD system. A 10ms ...
