Figure 10 be according to embodiments of the present invention in the flow chart for a kind of fast link recovery method in high-frequency mobile broadband connections, as shown in Figure 10, comprise the following steps:
Step S1002: dispatching station sends packet in the first wave beam group
In one embodiment of the invention, after dispatching station sends n times packet in the first wave beam group, or in the given time still without receiving the confirmation receiving packet that receiving station feeds back, namely think that the link of this packet occurs to worsen or disconnect, packet bust this, at this moment, receiving station will determine the channel quality adopting specified measurement reference signal to measure adjacent beams group.
The value of N or scheduled time length can be network side and terminal is made an appointment, it is also possible to be that network side passes through common signaling, controls signaling etc. and inform terminal.
Network side and terminal can the value of a pair N in the following manner count:
Mode one:
Network side, before sending each packet (including the packet retransmitted), all first sends a control signaling for dispatching this packet;
Terminal supposes to receive above-mentioned control signaling every time, and terminal is often receiving once above-mentioned control signaling, and the packet of network side transmission is counted by the instruction still retransmitting packet according to the new data packets in this control signaling.
Mode two:
Network side is in the n times packet sent to terminal, the control signaling dispatching this packet is have sent before having at least once, wherein this control signaling contains correspondence be scheduled packet be which time send, it is possible to further comprises the maximum round trip time delay that this packet sends every time and receives.
Packet is carried out synchronous counting by receiving above-mentioned control signaling by terminal.
Mode three:
Network side, while sending packet by the first wave beam group or after send the failure of n times packet by the first wave beam group, sends specified measurement reference signal to terminal in the second wave beam group.
Terminal is attempting receiving the first wave beam group in each subframe of packet simultaneously from the above-mentioned specified measurement reference signal of trial reception the second wave beam group, once blind check measures above-mentioned specified measurement reference signal, then utilize this appointment reference signal that the channel link qualities in the second wave beam group is measured, and carry out quickly channel link recovery again.
Preferably, above-mentioned appointment reference signal can be triggered by control signaling, can also comprise the instruction of the use resource to this appointment reference signal in this control signaling further.Wherein, it is intended that the use resource of reference signal includes but not limited to time-domain resource, frequency domain resource, reference signal sequence etc..
Mode four:
Network side just used the control signaling that robustness is higher to limit to the longest deadline that this packet of terminal notification transmits before packet sends first, if network side is from the confirmation receiving this packet starting to send packet first and start never to receive within the scope of this time restriction self terminal, then think that link there occurs deterioration or disconnects, then after having crossed this time restriction, network side sends appointment detection reference signal immediately, wave beam in second wave beam group is carried out link quality measurements, enters fast link recovery process;
Terminal has known the maximum transmission time restriction of this packet by receiving stronger the controls signaling of robustness, once limit from receiving the transmission time that control signaling starts beyond this maximum transmission time, but but without receiving this packet.Terminal is thought and this packet bust this is received above-mentioned appointment detection reference signal, and the link-quality of the second wave beam group is measured, and enters fast link recovery process.
Preferably, the control signaling that robustness is high refers to and is subject to the control signaling that terminal moves, the impact such as the change of external conditions such as terminal rotating, channel condition is smaller, and terminal is easier detection and receives this control signaling.Usual this control signaling is broadcast signaling or common signaling etc., uses wider wave beam or lower frequency resource to be transmitted, and it would furthermore be possible to send by some cycles.
In another embodiment of the present invention, packet sends ability after unsuccessfully and is sent to receiving station by dispatching station to specify reference signal not necessarily to wait until, but is sent to receiving station according to a kind of periodic mode at regular intervals in the resource that predefined or base station configure.The channel link qualities of receiving station's periodic measurement the second wave beam group, one or more beam information corresponding for the channel link qualities in the second wave beam group with optimum are regularly fed back to dispatching station by receiving station, or one or more beam information corresponding for the channel link qualities with optimum are only fed back to dispatching station when determining packet bust this by receiving station.

Dispatching station can send specified measurement reference signal to receiving station according to periodic mode or triggering mode in appointment resource in dispatching station the second wave beam group.
The resource of specified measurement reference signal can by predefined mode, or notify to terminal by the control signaling that high-level signaling or robustness are higher, or can pass through the last time be transferred to terminal descending/upstream control signaling or packet indicate the resource allocation information of reference signal to terminal.
The resource of specified measurement reference signal includes time-domain resource, frequency domain resource and the reference signal sequence etc. that this measuring reference signals uses.
Preferably, network side can send specified measurement reference signal on the continuous measuring hours unit of sent packet, or in the different measuring frequency cells of sent packet, send specified measurement reference signal, or in identical measuring, time quantum, identical measurement frequency cells send different witness mark sequences.Wherein, measurement time quantum, measurement frequency cells, measuring reference signals sequence are made an appointment by network side and terminal, or informed terminal by network side by common signaling, or informed terminal by network side by high-level signaling, or with terminal iidentification (Identity, referred to as ID), terminal place community ID, at least one is correlated with to be sent to the data package size of this terminal, type of service etc..
Measure time quantum, it is possible to be system time unit, or be made up of one group of continuous or discrete system time unit;Each measurement time quantum is for the channel link qualities between the one pair of which wave beam in measuring process 3 or receives Signal to Interference plus Noise Ratio (SignaltoInterferenceandNoiseRatio, referred to as SINR);Multiple measurement time quantums constitute the measurement time resource of (after this packet bust this) fast link recovery process.
Measure frequency cells, for system frequency unit, or be made up of one group of continuous or discrete system frequency unit;Each measurement frequency cells is for the reception SINR of the one pair of which wave beam pair in measuring process 3;Multiple measurement frequency cells constitute the measurement frequency resource of (after this packet bust this) fast link recovery process.
Measure time resource or measure frequency resource, it is possible to being that network side keeps for fast link recovery process, for instance it is periodic for measuring time resource, and measuring frequency resource is system bandwidth;It is also likely to be all or part of of the time shared by the packet being transferred to this terminal or frequency resource.
Wherein, packet failure n times or after being not received by confirmation in the given time, network side can also trigger specified measurement reference signal and carry out fast link recovery by controlling signaling.Wherein, control signaling can also comprise the resource distribution to detection reference signal.
Step S1006: receiving station measures the reception SINR on the wave beam in the second wave beam group respectively
