Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
It is described at ground, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in figure 3, one embodiment of the invention provides a kind of acquisition methods of timing-advance information, it is applied to terminal, packet
It includes:
Step 301, random accessing message is sent on object beam to base station；
It should be noted that timing advance (TA) information to be carried out to corresponding, an i.e. TA information with wave beam in the present embodiment
A wave beam is corresponded to, when terminal needs to obtain the TA information on some wave beam, only need to send random access on the wave beam
To indicate that base station feedback corresponds to the TA information of wave beam, the object beam in step 301 refers to be needed to obtain TA message
The wave beam of information.
Step 302, receive the base station fed back according to the random accessing message it is corresponding with the object beam fixed
Shi Tiqian TA information.
Base station is receiving random accessing message, need to only be somebody's turn to do according to the object beam for sending the random accessing message, feedback
The corresponding TA information of object beam.TA information herein generally refers to TA value.
It should be noted that the access way because of terminal is different, the specific implementation process of step 301 also can be different, optional
Ground, the first implementation of step 301 are as follows: obtain the triggering message that base station is sent, the triggering message instruction terminal carries out
Random access is to obtain at least one TA information；
It should be noted that the wave beam that the triggering message includes: progress random access is connect to link (BPL), at random
At least one the uplink beam information and progress random access entered obtains at least one at least one TA information.
The specific implementation for the triggering message that above-mentioned acquisition base station is sent are as follows: in the default signaling that base station is sent, obtain
The triggering message for taking base station to send；
The default signaling includes: physical downlink control channel PDCCH signaling or the dedicated letter for carrying the triggering message
It enables.
It should be noted that base station can new field can to carry the triggering message or base station in PDCCH signaling
With a newly-generated dedicated signaling, it is specifically used to carry out the transmission of triggering message.
According to the triggering message, the object beam for carrying out random access is determined；
Terminal can determine which TA information needed to obtain according to the triggering message, the TA information obtained as needed, just
It can determine that needs carry out random access on which wave beam.
On the object beam, random accessing message is sent to base station.
When terminal has determined the wave beam of random access, random accessing message is just sent on the wave beam to base station, to ask
Seek the corresponding TA information of base station feedback.
It should also be noted that, base station is not that whenever can send triggering message, base station is only determining permission
When terminal is sent using multi-beam, the transmission of triggering message just will do it, it is corresponding, the triggering that base station is sent, which is obtained, in terminal disappears
Before the step of breath, further includes:
For reporting ability information to base station, the ability information is used to indicate whether terminal supports multi-beam transmitting capacity, is
It is no to support more control panel transmitting capacities, whether support more control panels while sending the ability of more TA information and whether supporting single control
At least one in the ability of more TA information is sent in plate simultaneously.
Base station receives the ability information that terminal is sent, and determines whether that terminal is sent using multi-beam；
If terminal is allowed to send using multi-beam, triggering message will be sent to terminal.
It should be noted that the first implementation of step 301 needs base station to be triggered, only base station is being received
Triggering message after, terminal just will do it random access procedure.
The specific implementation process of such implementation are as follows:
Terminal can select a uplink beam to carry out random access procedure, get a BPL in initial access process
On TA information, after access, terminal reporting ability information is to base station；Base station is judging that terminal is allowed to make according to the ability information
When being sent with multi-beam, triggering message will be sent to terminal, random access procedure is carried out on other wave beams with triggering terminal
Obtain the TA information of other or multiple available links.
Optionally, second of implementation of step 301 are as follows:
Respectively in corresponding time-frequency domain Physical Random Access Channel (PRACH) resource of multiple object beams, send random
Message is accessed to base station.
It should be noted that in this way, terminal carries out the triggering that random access needs not move through base station, and terminal is certainly
Main initiates random access simultaneously on multiple uplink beams, to obtain at least one TA value.
In the second implementation, the different uplink beam of terminal is simultaneously in identical or different time-frequency domain PRACH
Random access preamble (preamble) is sent in resource, it should be noted that is sent on different uplink beams
Preamble can be the same or different.
It should be noted that because of the TA information that the TA information of base station feedback is at least one chain road, it follows that base station
The TA information of feedback may be multiple TA information of multiple chain roads, therefore, the specific implementation of step 302 are as follows:
Receive the base station fed back in presetting message according to the random accessing message it is corresponding with the object beam
At least one TA information；
Wherein, the presetting message includes: at least one in random access response RAR message and TA feedback message；
It should be noted that base station can by the way that when sending RAR message, at least one TA information is fed back to terminal,
Base station can be specifically used to carry out the feedback of at least one TA information with a newly-generated TA feedback message.
The TA information includes: TA value mark and TA value corresponding with the TA value mark；
It should be noted that it is that it is corresponding to be used to refer to TA value for TA value mark for which link；The TA value identifies
Uplink beam mark, BPL mark, wave beam group mark, there are the downlink wave beam of uplink and downlink wave beam corresponding relationship mark and port numbers
In one；
The TA value is that default value or the object beam correspond to the value of TA information and the difference of preset reference value.
It should be noted that base station can send specific TA value to terminal, can also send the offset of TA value to
Terminal, meanwhile, the reference quantity of TA value is arranged in base station, when terminal gets the offset of the TA value of base station transmission, only needs to utilize
The reference quantity of the offset and TA value carries out operation, can obtain the specific value of TA.
The embodiment of the present invention carries out with wave beam TA information corresponding by obtaining the corresponding TA information of object beam, avoids
The indistinguishable problem of the TA information of multi-beam ensure that terminal obtains accurate uplink synchronous, ensure that NR system is logical
Believe reliability.
As shown in figure 4, one embodiment of the invention provides a kind of feedback method of timing-advance information, it is applied to base station, packet
It includes:
Step 401, the random accessing message that terminal is sent on object beam is received；
Step 402, it according to the random accessing message, feeds back timing advance TA information corresponding with the object beam and gives
Terminal.
