Description
Technical field
The present invention relates to wireless communication technology field, more particularly to a kind of method, apparatus that sends of rlc layer state report and it is
System.
Background technology
In RLC (Radio Link Control, the Radio Link of LTE (Long Term Evolution, Long Term Evolution)
Control) AM (affirmation mode) pattern under, in order to ensure the reliability of transmission, by receiving side status report to sending side,
Sending side according to state report report as a result, being discharged to the datagram for having been received by confirmation, and to not receiving the datagram of confirmation
Retransmitted.
However, during the transmission of state report is realized, when scheduling bandwidth very little, less than state report length when, it is logical at present
Normal processing method is：According to the size of scheduling bandwidth, isloation state report is split as two, first state report is sent, and the
Two are abandoned, and set the transmission state of state report to be sent completely state.Since the state of state report is to be sent completely
State, causes when next scheduling bandwidth arrives, will not hair-like state report again, sending side can only be waited to trigger again.
The shortcomings that this way：The state report reported due to receiving side not in time, reports the data cached of sending side
Less than timely release, committed memory space, more seriously, after transmission window has been expired, does not receive upper strata and delivers and carry out data,
Stop data transfer.Similarly, since receiving side state report is sent not in time, the datagram of re-transmission is not retransmitted in time, influence
The reception data of receiving side are delivered to upper strata in time.
The content of the invention
The present invention provides the methods, devices and systems that a kind of rlc layer state report is sent, to solve to transmit in the prior art
The data sending side that state report is brought not in time sends data outage, data receiver side joint is received data and cannot be delivered in time to upper strata
The problem of.
To solve the above-mentioned problems, the present invention adopts the following technical scheme that：
On the one hand, the present invention provides a kind of method that rlc layer state report is sent, including：
Structural regime report, and it is state to be sent to set the state report；
