Problems solved by technology

Therefore, it may appear that the number of symbols included in a certain resource cannot meet the transmission power requirements of the uplink control signal. If the transmission method of using a fixed number of symbols in a resource to carry the uplink control signal in the prior art is followed, the terminal The device needs to wait for the resource containing the number of symbols that can meet the transmission power requirement to transmit the uplink control signal, resulting in waste of resources and increasing the transmission delay of the uplink control signal

Embodiment Construction

[0069] The technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in this application.

[0070] The terms "component", "module", "system" and the like are used in this specification to refer to a computer-related entity, hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and / or a computer. By way of illustration, both an application running on a computing device and the computing device can be components. One or more components can reside within a process and / or thread of execution and a component can be localized on one computer and / or distributed between two or more computers. In addition, these components can execute from various computer readable media having various data structures st...

Abstract

A method and device for transmitting an uplink control signal, the method comprising: a first device determines a first number of symbols; the first device sends an uplink control signal to a second device on at least one resource according to the first number of symbols, and the uplink The number of symbols included in the control signal is a second number of symbols, and the second number of symbols is greater than or equal to the first number of symbols. The method can reduce the time delay of transmitting the uplink control signal between the first device and the second device by sending the uplink control signal on at least one resource, and can save resource overhead.

Description

technical field [0001] The present application relates to the field of communications, and more specifically, to a method and device for transmitting an uplink control signal. Background technique [0002] In order to improve the accuracy and reliability of wireless communication, the second device and the first device will transmit an uplink control signal (or in other words, an uplink control channel) during communication. [0003] Moreover, in the prior art, the number of symbols used to carry uplink control signals in each uplink transmission subframe is fixed at 14, and each uplink control signal is transmitted on only one resource. [0004] However, with the development of communication technology, the number of symbols contained in each resource will change, not all resources contain 14 symbol resources of uplink control channels, and the number of symbols occupied by uplink control signals and transmission of communication services Power requirements also become div...
