Embodiment 1

[0224] See figure 1 An embodiment of the present invention provides a transmission method, which can be executed by a terminal, and the terminal can be implemented by a device capable of communicating with a base station, such as a personal computer (Personal Computer), a mobile phone, or a tablet computer. The flow of the method is described as follows, wherein, in the following flow, the description of the method at the base station side will also be involved.

[0225] S101: The terminal determines M-bit scheduling request SR information, where M is an integer greater than 1;

[0226] S102: The terminal simultaneously sends M-bit SR information and first uplink control information UCI to the base station.

[0227]In the embodiment of the present invention, the base station may configure at least one SR configuration for the terminal, and different SR configurations include one or more parameters that are different. Wherein, the terminal can choose which SR configuration to...

Embodiment 2

[0297] See figure 2 , based on the same inventive concept, an embodiment of the present invention provides a transmission method, the process of which can be described as follows:

[0298] S201: The base station receives the information sequence sent by the terminal on the transmission resource of the first PUCCH format, where the information sequence includes M-bit SR information and the first UCI, and M is an integer greater than 1;

[0299] S202: The base station obtains the M-bit SR information based on the information sequence, and determines SR states of multiple SR configurations configured for the terminal according to the M-bit SR information.

[0300] In a possible implementation manner, the M-bit SR information corresponds to the multiple SR configurations, wherein one bit in the M-bit SR information corresponds to one SR configuration, and the value of each bit is used for Indicates that the corresponding SR is configured as a positive SR state or a negative SR s...

Embodiment 3

[0325] See image 3 , the embodiment of the present invention also provides a terminal, where the terminal includes a memory 301 , a processor 302 and a transceiver 303 . Wherein, the memory 301 and the transceiver 303 can be connected to the processor 302 through a bus interface ( image 3 Take this as an example), or it can also be connected to the processor 302 through a dedicated connection line.

[0326] Wherein, the memory 301 can be used to store programs. The processor 302 can be used to read the program in the memory 301 and execute the following processes:

[0327] Determine M-bit scheduling request SR information, where M is an integer greater than 1;

[0328] The transceiver is configured to simultaneously send the M-bit SR information and the first uplink control information UCI to the base station.

[0329] In a possible implementation manner, the M-bit SR information corresponds to the multiple SR configurations, wherein one bit in the M-bit SR information c...

Abstract

Embodiments of the present invention provide a transmission method, a terminal, and a base station to solve the problem in the prior art of how to distinguish which SR in multiple SR configurations is transmitted simultaneously with other UCIs. It is a technical problem that the SR of the terminal performs correct uplink scheduling. In the transmission method for distinguishing multiple SR configurations provided by the embodiment of the present invention, the terminal concatenates the M-bit scheduling request SR and the first UCI together for simultaneous transmission, and indicates the SR status of multiple SR configurations of the terminal through the M-bit SR information, so that This ensures that the base station performs correct uplink scheduling on the terminal.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a transmission method, a terminal and a base station. Background technique [0002] With the development and change of mobile communication service requirements, many organizations such as the International Telecommunication Union (ITU) have begun to study a new wireless communication system (5Generation New RAT, 5G NR) for future mobile communication systems. [0003] In the 5G NR system, the terminal may have multiple scheduling request (Scheduling Request, SR) configurations, and the parameters of each SR configuration are different, such as SR resources, period, etc., when there are multiple SR configurations occurring at the same time When overlapping, the Media Access Control (MAC) layer of the terminal may only notify the terminal that one of the SRs is configured for transmission at the physical layer, that is, the positive SR is transmitted. When the SR is...
