Embodiment Construction

[0085] The technical solution in this application will be described below with reference to the accompanying drawings.

[0086] 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 stored thereon. A component may, for example, b...

Abstract

The present invention provides a resource mapping method and device. The method includes the following steps that: a terminal device receives resource configuration information sent by a network device, wherein the resource configuration information is used to indicate the parameter information of N frequency hopping bandwidth parts for the terminal device, wherein N is larger than or equal to 2,and the bandwidth length of any one of the N frequency hopping bandwidth parts is smaller than or equal to the bandwidth length of the active state bandwidth part (active-BP) of the terminal device; and the terminal device determines uplink physical transmission resources allocated by the network device according to the resource configuration information and uplink scheduling information. According to the resource mapping method and device of the invention, the bandwidth length of any one of the N frequency hopping bandwidth parts is smaller than or equal to the bandwidth length of the activestate bandwidth part (active-BP) of the terminal device, so that the terminal device will not hop out of the active state bandwidth part (active-BP) of the terminal device when perform frequency hopping according to the parameter information of any one of the N frequency hopping bandwidth parts.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to a method and device for resource mapping in the field of communications. Background technique [0002] In the Long Term Evolution (LTE) system, the transmission of the Physical Uplink Shared Channel (PUSCH) of the user equipment (User Equipment, UE) uses the OFDM (Discrete Fourier Transform-Spread) extended by discrete Fourier transform. OFDM, DFT-S-OFDM) waveform. [0003] In order to make the peak-to-average power ratio (Peak to Average PowerRatio, PAPR) of PUSCH using the DFT-s-OFDM waveform relatively low, and to use the power amplifier of the UE as efficiently as possible to improve uplink coverage, PUSCH transmission usually uses continuous physical resource blocks ( Physical Resource Block (PRB) resource, for PUSCH transmission of a continuous PRB resource, in order to improve the diversity gain of PUSCH, the PUSCH transmission in the LTE system supports i...
