Problems solved by technology

[0005] However, considering that the result of LBT is real-time, that is, the LBT initiated by the network device may succeed in different locations, then based on the above indication method, the network device needs to update the indication information of the DCI in real time to indicate the time domain resources of the terminal device data. very wasteful of resources

Embodiment approach

[0324] Portion 1820 may include one or more single boards, each single board may include one or more processors and one or more memories. The processor is used to read and execute the program in the memory to realize the baseband processing function and the control of the base station. If there are multiple single boards, each single board can be interconnected to enhance the processing capability. As an optional implementation manner, multiple boards may share one or more processors, or multiple boards may share one or more memories, or multiple boards may share one or more processors at the same time. device.

[0325] For example, in one implementation, the transceiver unit of part 1810 is used to execute Figure 9 The sending operation on the network device side in step 910 and step 920 shown in , and / or the transceiver unit in step 1810 is also used to perform other sending and receiving steps on the network device side in the embodiment of the present application. The ...

Abstract

The invention provides a method for receiving and sending data and a communication device, so as to avoid resource waste and save signaling overhead. The method may comprise the steps that: a terminaldevice receiving downlink control information (DCI), the DCI being used for indicating a time domain resource indication, the time domain resource indication comprising information about a relative position between a time domain resource for transmitting data and a time domain resource for transmitting the DCI; and the terminal device determines an initial position of a time domain resource for transmitting data, and receives the data based on the initial position.

Description

technical field [0001] The present application relates to the field of communication, and more particularly, to a method and a communication device for receiving data and sending data. Background technique [0002] The rapid development of wireless communication technology has led to an increasingly scarce spectrum resource, which has promoted the exploration of unlicensed frequency bands. The 3rd Generation Partnership Project (3GPP) introduced license assisted access (LAA) in release 13 (release-13, R-13) and release 14 (release-14, R-14) respectively ) and enhanced license-assisted access (enhanced LAA, eLAA) technology, that is, non-standalone (non-standalone) deployment of LTE / LTE-A systems on unlicensed spectrum, through the assistance of licensed spectrum to maximize the use of unlicensed spectrum resource. [0003] Communication systems deployed on unlicensed spectrum (unlicensed spectrum) usually use or share wireless resources in a contention manner. Generally, ...
