Fruit, base station make decisions whether the terminal needs to carry out uplink switching according to measurement result, if necessary to carry out uplink switching, just
Down link control information (Downlink Control Information, DCI) is sent to the terminal, indicates the terminal
It is switched to the running time-frequency resource position of new up-link carrier, the terminal continues to send data on new up-link carrier.
For being configured with the cell of SUL carrier wave and PUL carrier wave, when terminal moves towards fringe region from central area, PUL is carried
Wave mass can sharply decline, if terminal at this time on PUL carrier wave initiate random access (random access, RA) or into
Row radio link layer control protocol (Radio Link Control, RLC) layer data transmission, it is more likely that due to PUL carrier wave item
Part is deteriorated, and leads to RA failure or reach rlc layer maximum retransmission, and then trigger Radio Link Failure (Radio Link
Failure, RLF) process.It, can gravity treatment progress cell searching and wireless heterogeneous networks (Radio after terminal enters RLF

Configuration information instruction is stated to measure the RSRP or RSRQ of synchronization signal, then the terminal to the RSRP of the synchronization signal or
RSRQ is measured, for another example configuration information instruction measures the RSRP or RSRQ of CSI-RS, then the terminal pair
The RSRP or RSRQ of the CSI-RS is measured.
First thresholding≤downlink reference signal measurement result≤the second thresholding indicates that the terminal is positioned over model
Enclose the borderline region of lesser up-link carrier, such as positioned at the borderline region of first up-link carrier, first thresholding and
Second thresholding can be received by broadcast channel or dedicated channel from the network equipment, and it is pre- to be also possible to the terminal
First thresholding and second thresholding are first configured, the present embodiment does not limit.
Step 601, the terminal is opened when using the SPS resource to send the data on second up-link carrier
Move the first timer.
Step 602, before the first timer time-out, whether the terminal receives the ACK feedback of network equipment transmission
If the terminal does not receive the ACK feedback of the network equipment, touching before the first timer time-out
Radio Link Failure (RLF) process of hair；Or, being set if the terminal receives the network before the first timer time-out
Standby ACK feedback determines successful switch to second up-link carrier, and the terminal continuation is in second up-link carrier transmission
Upstream data, for example, sending the upper line number using the ascending resource that the SPS resource or the network equipment are redistributed
According to the terminal resets the first timer.
Step 603, the network equipment determines that up-link carrier switching occurs for the terminal.
When the network equipment receives the upstream data that the terminal is sent from the SPS Energy Resources Service of second up-link carrier
When, so that it may it determines that UL switching has occurred in the terminal, then sends corresponding ACK to the terminal, and configure before withdrawing
The SPS resource.
As can be seen from the above description, when terminal is at the overlapping region of the up-link carrier of two different channels, when the end
A up-link carrier sends signal weaker wherein at end, such as the random access number of transmission reaches threshold value or rlc layer re-transmission time
Number is when reaching threshold value, can to avoid triggering RLF process, but triggering be switched to another up-link carrier initiate random access or
Upstream data directly is sent using the SPS resource of another up-link carrier, avoids the prolonged interruption of communication.
