Specific embodiment
The embodiment of the present invention is described with reference to the attached drawing in the embodiment of the present invention.
Fig. 1 be the present embodiments relate to a kind of communication system architecture schematic diagram, the communication system includes multiple bases
It stands and multiple terminal devices.Fig. 1 a shows the 1a network equipment and 2 terminal equipment in communication.The communication system can be the whole world

(such as newly eating dishes without rice or wine (new radio, NR)) system, a variety of communication technologys fusion communication system (such as: LTE technology and NR skill
The communication system of art fusion) or subsequent evolution communication systems.It should be noted that the network equipment and base station equipment in Fig. 1 a
Quantity and the exemplary only explanation of form, not to the embodiment of the present invention constitute limit.
In long term evolution communication system, the random access procedure between terminal device and the network equipment is as shown in Figure 1 b.
S101, the network equipment send system information to terminal device, and terminal device receives the system letter that the network equipment is sent
It ceases, the parameters such as maximum retransmission can be carried in system message.S102, terminal device send random access preamble to the network equipment
(msg1, message 1), the random access preamble that network equipment receiving terminal apparatus is sent.S103, the network equipment are sent out to terminal device
It send random access response (msg2), terminal device receives the random access response that the network equipment is sent；It is wrapped in random access response
Include random preamble index and uplink scheduling authorization (UL grant).S104, terminal device send to the network equipment and dispatch for the first time
The message 3 (msg3) of transmission, the message 3 for the first time scheduled transmission that network equipment receiving terminal apparatus is sent；Terminal device root
Scheduled transmission message 3 (msg3) is sent according to the time-domain position and frequency domain position indicated in uplink scheduling authorization；If the network equipment is just
Really reception message 3 then sends message 4 (msg4) for solving conflict to terminal device, and conflicting, it is identical to make to refer to that multiple users use
Ascending resource initiating random access procedure, and the network equipment thinks that only 1 user initiates random access.S105, network are set
It is standby to send Schedule retransmission to terminal device, scheduling weight is sent by DCI (downlink control information, DCI)
It passes.S106, terminal device are retransmitted to network equipment scheduled transmission.S107, the network equipment send contention resolved to terminal device
(msg4, message 4).
When message 3 is transmitted, due to channel fading, interference, sends that power is too low or the factors such as multiple users conflict, cause
The network equipment receives message 3 and fails.It again can be message 3 by Downlink Control Information when the network equipment receives message 3 and fails
Dispatch resource.In long term evolution communication system, the network equipment dispatches resource, downlink control using descending control information format 0
The structure of information format 0 is as shown in table 1.Wherein, scheduling of resource field (resource block assignment and
Hopping resource allocation) scheduling message 3 retransmit frequency domain resource.The maximum retransmission of message 3 is by being
It is indicated in system information, when the number of retransmissions of message 3 is more than maximum retransmission, terminal device retransmits random access preamble
Or random access problems are reported to high level.
In message 2, the network equipment can assign Temporary Cell Radio Network temporary identifier (temporary to terminal device
Cell-radio network temporary identifier, TC-RNTI) it is used for the scrambling of message 3.If the network equipment
It detects 3 transmission success of message and message 4 successfully solves conflict, face TC-RNTI as the cell-radio network of terminal device
When identify (cell-radio network temporary identifier, C-RNTI).

Table 1
According to the random access procedure of above-mentioned long term evolution communication system, the network equipment can match again when message 3 retransmits
Resource and power are set, can solve by channel fading or the transmission of message 3 caused by interfering fails, but there is no solve conflict.
When a collision occurs, the network equipment is notified that terminal device retransmits always message 3, causes biggish access delay.
A and Fig. 2 b referring to fig. 2, in new idle port communication system, the network equipment and terminal device may use multiple wave beams
It is communicated, equally exists the problem that collision probability is big, and access delay is grown.Such as: as shown in Figure 2 a, multiple terminal devices use
Identical random access preamble, multiple terminal devices receive the network equipment transmission random access response when, be regarded as to
The uplink scheduling authorization of oneself, therefore multiple terminal devices send message 3 on identical ascending resource, to cause to conflict.
As shown in Figure 2 b, under multi-beam scene, terminal device is when initiating random access, in order to rapidly join, uses wider wave
Shu Jinhang communication, wider wave beam acquisition antenna gain is low, and the network equipment may cannot be correctly received message 3, thus cause
The transmission of message 3 fails.
It is big in order to solve the collision probability that the re-transmission of message 3 in current random access procedure occurs, access delay length
Problem, present applicant proposes a kind of repeating methods of message 3: when the network equipment detects the transmission failure of message 3, sending out to terminal device
A Downlink Control Information is sent to dispatch multiple ascending resources, terminal device selects 1 or more from multiple ascending resources of scheduling
A ascending resource retransmits one or more message 3, to reduce the probability clashed when message 3 retransmits, reduces time delay；Or net
It when network equipment detects the transmission failure of message 3, sends multiple Downlink Control Information and dispatches multiple ascending resources, terminal device is from more
It selects one or more ascending resources to retransmit at least one message 3 in a ascending resource, is clashed to reduce and retransmit message 3
Probability, reduce time delay；Or when the network equipment detection transmission failure of message 3, dispatch multiple ascending resources, terminal device is from multiple
One or more ascending resources are selected to send one or more message 3, detection with reference to letter using narrower wave beam in ascending resource
Number (sounding reference signal, SRS), channel state information reference signals (channel state
Information reference signal, CSI-RS), so that promoting message 3 detects successful probability.
Terminal device in the application is a kind of equipment with wireless communication function, be can be with wireless communication function

Fig. 3 is referred to, Fig. 3 is a kind of flow diagram of the method for communication provided in an embodiment of the present invention, this method packet
It includes but is not limited to following steps:
S301, terminal device send message 3, the message 3 that network equipment receiving terminal apparatus is sent to the network equipment.
Specifically, it is the data just passed that the transmission of message 3 is available in this step, is also possible to the data retransmitted.In this step
Before rapid, the network equipment sends system message to terminal device, and terminal device sends random access preamble to the network equipment
(msg1), the random access preamble that network equipment receiving terminal apparatus is sent, the network equipment send random access to terminal device
It responds (msg2).Wherein, the transmission process of message 1 and message 2 can be found in the description in long term evolution communication system, herein no longer
It repeats.
S302, network equipment detection message 3 send failure.
In a kind of possible embodiment, the network equipment can determine the reason of message 3 fails according to signal quality, and
Determine scheduling for multiple ascending resources of re-transmission and/or the quantity of multiple ascending resources.Such as: signal quality is reference signal
