Description

Method for discontinuous reception and wireless access network node and terminal Technical field

The present invention relates to the field of communications technologies, and in particular, to a method for discontinuous reception in an unlicensed spectrum, and a radio access network node and a terminal.

Background technique

Up to now, it is well known that Long Term Evolution (LTE) systems are deployed and operated in licensed carriers. However, with the evolution of LTE, in the second half of 2013, some companies (such as Qualcomm Inc.) proposed to study the issue of LTE deployment in unlicensed carriers. With the rapid growth of data services, the licensed spectrum will not be able to withstand such a huge amount of data in the near future. Therefore, it is recommended to consider deploying LTE in the unlicensed spectrum to share the data traffic in the authorized carrier through the unlicensed spectrum. Unlicensed carrier (exempted spectrum) refers to the spectrum (or carrier) that can be used directly without authorization, subject to the relevant regulations (radio control) of government agencies (eg, National Radio Regulatory Commission). For example, microwave ovens, remote control toy airplanes, wireless mice, wireless keyboards, and Wireless Fidelity (WiFi) use unlicensed carriers.

In the conventional LTE system, the DRX (Discontinuous Reception) technology is adopted for the power saving of the terminal, and the terminal can periodically perform monitoring of the PDCCH (Physical Downlink Control Channel) according to the configuration. In the scenario where unlicensed spectrum-assisted data transmission is used, the radio access network needs to obtain the resources of the unlicensed spectrum through competition, and cannot always occupy the resource. If the terminal adopts the existing DRX mechanism and the terminal periodically monitors the PDCCH, Will form unnecessary monitoring behavior of the terminal, resulting in wasted power. How to perform DRX on the unlicensed spectrum is a problem that needs to be solved.

On the unlicensed spectrum, all devices perform resource preemption in the time domain. If the resources are preempted, the resources have the right to use resources. Each device can only release resources for a period of time, and resources must be released by other devices. use. Therefore, after each device preempts a period of resources in the time domain, it continues to randomly preempt at the next time, thereby ensuring that all devices use the unlicensed spectrum resources fairly. Therefore, the use of unlicensed spectrum resources by each device is non-contiguous and random in the time domain.

For the radio access network node, the resource is obtained by the resource preemption for a period of time, so that the downlink data can be sent to the terminal, and the terminal receives the data on the unlicensed spectrum, thereby improving the data traffic. The existing DRX mechanism is that the terminal periodically performs discontinuous reception of the PDCCH to obtain power saving. The periodic continuity of DRX and the discontinuity and randomness of the radio access network nodes to the unlicensed spectrum resources are contradictory.
