The process for receiving M random access preamble to the network equipment below is illustrated: the network equipment receives M at random
When any one random access preamble in access lead, the random access preamble is responded.Optionally, when the network equipment receives
When any number of random access preambles in M random access preamble, one of random access preamble is responded, such as: it rings
The top-quality random access preamble of induction signal, another example is: the random access preamble that response is initially received.Optionally, work as net
When network equipment knows the random access preamble that terminal device may be sent and corresponding time frequency position, the network equipment is received
In the case where any one random access preamble in multiple random access preambles, stops detection and sent by the same terminal device
Other random access preambles.
In at least one random access chance within the random access response window time, if network equipments configuration is to terminal
At least one in multiple random access preambles of equipment is located in the random access chance, then the network equipment continues to simultaneously
Detect random access preamble.In one implementation, the network equipment can respond at least one inspection in a response message
The random access preamble measured.Optionally, random access response in the response message is detected according to network equipment reception
The power of the corresponding signal quality of random access preamble is configured.Such as: in the response message, the network equipment receives signal matter
Strong (terminal device is sent) corresponding random access response of random access preamble of amount, positioned at weak random of received signal quality
Before the corresponding random access response of access lead.Again for example: in the response message, network equipment received signal quality it is strong with
The corresponding random access response of machine access lead, positioned at receive the weak corresponding random access response of random access preamble of signal it
Before.
In one implementation, in random access response window, the network equipment by M response message respond M it is a with
Machine access lead, terminal device receive M response message.Optionally, the chronological order that M response message is sent, according to
The network equipment receives the strong and weak of the corresponding signal quality of random access preamble detected and places, and/or in the response message
Random access response receives the strong and weak of the corresponding quality signal of random access preamble detected according to the network equipment and places.Example
Such as: the network equipment sends the response message of (counterpart terminal equipment receives first in time), response message first in time
The random access preamble of middle response, (counterpart terminal equipment is in time than sending afterwards in time for corresponding received signal quality
Receive first) response message in the random access preamble that responds it is good.Again for example: it is (right that the network equipment is sent first in time
Answer terminal device to receive first in time) response message, the random access preamble responded in response message, corresponding reception
Signal quality responds random in the response message than sending (counterpart terminal equipment receives first in time) afterwards in time
Access lead is poor.
It optionally, further include random access resource where random access preamble in implementation above mode, in response message
Time and/or frequency location.
Optionally, in implementation above mode, in response message further include the network equipment receive at least one is random

In one implementation, after terminal device receives first random access response, stop sending other random
Access lead.
In one implementation, after terminal device receives M random access response that be pre-stored or being pre-configured, stop
Other random access responses are only received, and/or stop sending other random access preambles.
In other implementation, the sending method of random access response is indicated by configuring information of network appliance, terminal
Equipment is according to instruction information receiving random access response, including but not limited to: the number of the quantity of response message, random access response
The time sequencing and terminal device that amount, random access preamble are sent send beam gain, the relationship of downlink signal quality power, sound
Answer at least one of the sequencing of random access response in message, relationship of random access preamble received signal quality power.
Implement Fig. 4 embodiment, the embodiment of implementing Fig. 3, when sending multiple random access preambles, wave beam increases terminal device
The poor signal quality of the good random access preamble downlink signal low prior to beam gain of beneficial high and downlink signal signal quality
Wave beam is sent, and terminal device can first receive the decode the high random access preamble of beam gain, reduce the access of random access
Time reduces access delay.
In other implementation, terminal device needs to receive net respectively using multiple and different reception beam directions
The downlink signal of network equipment multiple directions.In this case, it is desirable that terminal receives beam direction and the downlink of the network equipment is believed
Number direction match, to improve the performance and efficiency of link transmission.At this point, in the multiple random access preambles of network equipments configuration
It when transmission, needs to consider some limitations, guarantees that user equipment can be in correct beam direction receiving random access response.
For example, the associated downlink signal of multiple random access preambles of network equipments configuration, terminal uses identical reception
Wave beam (or the corresponding parameter standard of the multiple reception wave beams of terminal is co-located: delay spread, Doppler spread, Doppler
Shift, average delay, and spatial Rx parameters) good performance can be obtained；Or it is described more
A random access preamble corresponds to beam direction (the i.e. all or part of spatial parameter phase of the downlink signal of the identical network equipment
Corresponding delay spread, Doppler spread, Doppler shift with perhaps close or multiple downlink signals,
Average delay, and spatial Tx parameters standard is co-located)；Or the multiple random access preamble association is together
One downlink signal.
Again for example: the corresponding random access preamble of the multiple and different downlink signals of network equipments configuration, terminal determine transmission
When multiple random access preambles, the corresponding random access preamble response of multiple random access preambles that the terminal determines has
Following characteristics: can be received by identical terminal reception wave beam (or the corresponding parameter standard of the multiple reception wave beams of terminal is co-located:
delay spread,Doppler spread,Doppler shift,average delay,and spatial Rx
Parameters) or terminal is had the ability while being received from multiple random access responses for receiving beam direction, the multiple
The corresponding response of random access preamble is within this multiple reception beam direction；Terminal multiple random access preambles it is corresponding with
In machine access response reception window, the receiving random access response on the multiple reception beam direction.
Again for example: terminal device is not intended to/can not at the same time, go to receive using multiple wave beams may be from not
Equidirectional random access response, terminal can be to network equipment feedback information at this time, and the network equipment is according to the feedback information tune
Spend multiple random access preambles to terminal, the corresponding random access response of the multiple random access preamble can be by identical/phase
Like direction (or the corresponding parameter standard of the multiple reception wave beams of terminal is co-located: delay spread, Doppler spread,
Doppler shift, average delay, and spatial Rx parameters) terminal receive wave beam receive.Example again
Such as, terminal is only received in a beam direction (or antenna port, such as omnidirectional receive ability), and the network equipment can at this time
The associated random access preamble of downlink signal arbitrarily to dispatch/configure multiple and different down directions gives the terminal.
In other implementation, multiple associated multiple random access preambles of downlink signal, corresponding random access
The different time responded in random access response window is sent.At this point, terminal device can receive in section respectively in different times
The corresponding response of different random access lead, at this point it is possible to the random access preamble of terminal device selection is not limited, and/
Or multiple random access preambles of network equipments configuration are not limited.
