Abstract

The embodiment of the invention discloses a time domain resource allocation method and a device, and relates to the technical field of communication. The transmission performance of data transmissioncan be ensured by allocating reasonable default candidate resources. The method comprises the following steps: determining N pieces of candidate time domain resource information, wherein N is greaterthan or equal to 2; and receiving indication information, wherein the indication information is used for determining time domain resources allocated to the data channel from the N pieces of candidatetime domain resource information. Wherein for at least one frame structure parameter in the M frame structure parameters, M is a natural number; wherein the time domain resource indicated by at leastone piece of candidate time domain resource information in the N pieces of candidate time domain resource information is different from the time domain resource used by at least one of the following signals and / or channels in the LTE: a cell common reference signal CRS, a physical downlink control channel PDCCH, a multimedia broadcast single frequency network MBSFN, a main synchronization signal PSS, an auxiliary synchronization signal SSS and / or a broadcast channel PBCH.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a time domain resource allocation method and device. Background technique [0002] In a communication system, when a network device and a user equipment (User Equipment, UE) perform data transmission, the network device may schedule the UE, for example, may allocate frequency domain resources and / or time domain resources of a data channel to the UE through control information. In 5G new radio (New Radio, NR), the transmission of the data channel is on part of the frequency domain resources (Bandwidth Part, BWP), and the occupied time domain symbols can be changed dynamically, for example, it can be selected from the first time slot or subframe A symbol starts transmission, or any other symbol starts, and the end symbol can also be anywhere in the slot or subframe. The time domain resources specifically used for data transmission need to be determined by th...
