Description

Uplink transmission method, device and terminal

Technical Field

The present application belongs to the technical field of wireless communication, and in particular, to a method, an apparatus, and a terminal for uplink transmission.

Background

A Physical Uplink Control Channel (PUCCH) is a Physical Channel of an Uplink in a New Radio (NR) system, and is used to carry Uplink Control information. The purpose of setting the PUCCH is: when a User Equipment (UE), that is, a terminal or a UE, is not scheduled, that is, is not allocated Uplink Shared Channel (ULSCH) resources, the UE uses the PUCCH to transfer Uplink Control Information (UCI) of Layer1 or Layer2 (Layer 1/Layer2, L1/L2), such as a Channel state report, a hybrid automatic Repeat request (HARQ) acknowledgement and a scheduling request.

In the related art, when performing uplink transmission, a cyclic shift mechanism is usually used to process a PUCCH sequence to increase user multiplexing capacity. For example, for a dedicated (truncated) PUCCH Format (PUCCH Format, PF) 0, a maximum of 6 UEs may be multiplexed (harq ack is 1 bit) with the same PUCCH time-frequency resources; for another example, for the dedicated PF1, in case that PUCCH time-frequency resources are the same, a maximum of 12 UEs may be multiplexed (only multiplexing in frequency domain is considered).

However, for the enhanced PUCCH with multiple Physical Resource Blocks (PRBs), the sequence length may change, and in this case, if the PUCCH cyclic shift mechanism provided in the related art is still used for uplink transmission, orthogonality of the PUCCH sequences cannot be fully utilized, which results in low Resource utilization rate.

In this embodiment, the method 200 may include at least the following steps.

S210, the terminal determines a target PUCCH sequence based on the target cyclic shift value.

Wherein the target cyclic shift value is determined from the first information.

The first information includes at least one of a number of Resource Blocks (RBs) occupied by a PUCCH Resource, a number of Resource Elements (REs) occupied by each RB, and a length of the PUCCH sequence, and the PUCCH Resource is a Resource for transmitting the target PUCCH sequence.

It is to be appreciated that one PUCCH resource may be used for transmission of multiple PUCCH sequences, but different PUCCH sequences may correspond to different or the same target cyclic shift value.

In this embodiment, the format of the PUCCH sequence may be any one of PF0, PF1, PF2, PF3, and PF4, and the sequence type of the PUCCH sequence may be a long sequence or a short sequence. It should be noted that, in the present embodiment, for PUCCH sequences of different formats, where PF0 and PF1 refer to sequences of PUCCH format 0 and sequences of PUCCH format 1, and PF4 refers to Demodulation Reference Signal (DMRS) sequences of PUCCH format 4.

In one possible implementation, when the PUCCH sequence is an enhanced multi-PRB PUCCH sequence and the sequence type supports one long sequence, the sequence length is the same as the number of REs occupied by the PUCCH sequence.

Or, when the PUCCH sequence is an enhanced multi-PRB PUCCH sequence and the sequence type supports a short sequence, the sequence length is the same as the number of REs occupied by the PUCCH in one RB, and cyclic shift may be performed between different RBs.

Or, a specific sequence is supported in the sequence type of the enhanced multi-PRB PUCCH sequence of the PUCCH sequence, the length of the specific sequence can be divided by the number of REs occupied by the PUCCH sequence, and cyclic shift can be performed between different sequences.

S220, the terminal carries out uplink transmission based on the target PUCCH sequence.

In this embodiment, when performing uplink transmission, the terminal determines a target cyclic shift value according to at least one of the number of RBs occupied by the PUCCH resource, the number of REs occupied by each RB, and the length of the PUCCH sequence, so that the target cyclic shift value corresponds to the length of the PUCCH sequence, thereby making full use of the orthogonal property of the PUCCH sequence, improving the resource utilization rate, and expanding the user multiplexing capacity.
