Embodiment Construction

[0172] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0173] The present invention aims at the problem that ACK and / or NACK feedback cannot be correctly performed on multiple PDSCHs simultaneously received on the same serving cell in the prior art, and provides a method for transmitting feedback information, which can be applied to the terminal side, such as figure 1 shown, including:

[0174] Step 11: receiving configuration information sent by the base station, and determining the number of beam groups according to the configuration information;

[0175] Step 12: According to the number of beam groups, determine the number of bits of HARQ-ACK confirmed by HARQ;

[0176] Step 13: Generate a HARQ-ACK sequence corresponding to the number of bits, and send it to the base station.

[0177] Among them, HARQ-A...

Abstract

The invention provides a feedback information transmission method and device, a terminal, a bae station and a computer readable storage medium. The feedback information transmission method comprises the following steps: receiving configuration information sent by a base station, determining the number of beam group according to the configuration information; determining the bit number of hybrid automatic retransmission request acknowledgment (HAQR-ACK) according to the number of beam group; producing the HARQ-ACK sequence corresponding to the bit number, and sending to the base station. Through the scheme provided by the invention, the ACK and / or NACK feedback information can be correctly produced when the terminal receives multiple downlink transmissions using different beams at the sametime, thereby guaranteeing that the understandings on the ACK and / or NACK feedback information by the terminal and the baes station are consistent; and the problem that the ACK and / or NACK feedback cannot be correctly performed when the same service cell receives multiple PDSCHs at the same time in the prior art can be well solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a feedback information transmission method, device, terminal, base station, and computer-readable storage medium. Background technique [0002] Currently, in the LTE system, a terminal can only receive one Physical Downlink Shared CHannel (PDSCH) in one serving cell in one subframe. For a Frequency Division Duplex FDD (Frequency Division Dual) system, the feedback timing is n-4, that is, the PDSCH received in subframe n-4 performs positive acknowledgment ACK and / or negative acknowledgment NACK (ACKnowledgment / Non- ACKnowledgement) feedback. For a Time Division Duplex TDD (Time Division Duplexing) system, the feedback timing is different for different TDD uplink and downlink configurations. For example, as shown in Table 1, the PDSCH received in subframe n-k is ACKed and / or NACK feedback, where the K set may contain more than one element, which means that the PDSC...
