Embodiment approach

[0175] In practical applications, when the carrier load on the unlicensed spectrum is heavy, the secondary base station is likely to be unable to compete for the channel and cannot transmit downlink data, and the SGW cannot know whether the primary secondary cell or the secondary cell provided by the secondary base station is available. In this case, if the serving gateway SGW continues to send data to the secondary base station, the buffer of the secondary base station will be insufficient, resulting in data packet loss. To a certain extent, the transmission resources of the S1-U interface are not fully utilized , resulting in waste, resulting in full utilization of idle transmission resources. To solve this problem, flow control information is generally introduced between the SeNB and the SGW, and the SeNB periodically sends indication messages to the SGW. The specific implementation methods are as follows:

Abstract

The embodiment of the present invention discloses a radio resource scheduling method and related equipment. The method includes: the terminal according to the first state information of the channel indicated by the secondary base station and the second state information of the channel obtained by the terminal at least one of the above, determine the channel state of the channel, and send a first notification message indicating the channel state to the main base station, so that the main base station performs wireless resource allocation for the terminal according to the first notification message scheduling. The primary base station allocates more wireless resources to the above-mentioned terminals when the secondary base station does not schedule the terminal, and can obtain more opportunities for allocating wireless resources, thereby effectively improving the utilization rate of wireless resources to a certain extent.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for scheduling wireless resources and related equipment. Background technique [0002] With the rapid development of packet services and intelligent terminals, the demand for spectrum for high-speed and large-volume services is increasing, and it is necessary to achieve higher spectrum efficiency. The authorized frequency in the Long Term Evaluation Advanced (LTE-A, Long Term Evaluation Advanced) system Licensed assisted access (LAA, licensed assisted access) applies LTE-A cellular communication technology to unlicensed spectrum to improve utilization of unlicensed spectrum resources and increase available spectrum bandwidth for LTE users. Among them, the unlicensed spectrum includes frequency bands used for industrial, scientific and medical equipment. LAA is a scenario of carrier aggregation (CA, carrier aggregation) based on licensed spectrum a...
