Fig. 1 is a kind of schematic diagram for realizing scene of the transmission wave beam of base station and the reception wave beam of terminal device.Such as Fig. 1 institute Show, an ellipse represents a wave beam in figure, when base station sends information to terminal device, only in intermediate transmission wave beam Signal can be with incoming terminal equipment, terminal device also can only receive signal from intermediate reception wave beam.Other wave beams all without Method receives signal.Therefore, base station will send information to terminal device, it is necessary to which advanced traveling wave beam matching determines correct base station Transmission wave beam and terminal device reception wave beam.Likewise, terminal device is also required to carry out wave beam when sending information to base station Matching.However, not matched also when terminal device just accesses cell with the transmission wave beam of base station and reception wave beam.At this moment, it Carry out sending and receiving for information, it is necessary to advanced traveling wave beam scanning.For example, base station is receiving the message in random access procedure It when 1, needs to go to receive message 1 respectively using multiple reception wave beams, can just receive message 1 and determines correctly reception wave beam.

Also, in terminal device initial access process, in order to realize preferable covering, higher hair is can be used in base station Power is penetrated, so that the angle of the transmission wave beam of base station is wider.However, for terminal device, due to its energy constraint, It is not available too high power, causes the transmission wave beam of terminal device often relatively narrow.Base station increases to obtain higher reception Benefit also will use corresponding relatively narrow reception wave beam and go to receive.This results in base station to send signal from wider wave beam, but from relatively narrow Wave beam receive the scene of signal, such as scene shown in Fig. 2.In Fig. 2, the send wave beamwidth of base station, reception wave beam is narrow, and one Send the range that wave beam covers two reception wave beams.

In addition, terminal device is before a random access, the transmission of base station can be determined by way of receiving synchronization signal Wave beam.I.e. terminal device can determine which of base station sends wave beam and be in alignment with oneself, and by the send wave of determining base station Beam notifies base station by the message 1 in random access procedure.The method of terminal device notice be transmission wave beam based on base station with The incidence relation of running time-frequency resource used by the message 1 that terminal device is sent.That is the message 1 of base station receiving terminal apparatus transmission When, the running time-frequency resource that the uses when terminal device sends message 1 is measured, according to running time-frequency resource and sends the corresponding relationship of wave beam, Base station can know that its which transmission wave beam is in alignment with the terminal device.Will lead to using this technology, base station it is same The terminal device in beam coverage is sent, message 1 can be all sent using same running time-frequency resource.If multiple terminal devices Just having used same lead code again, (in random access procedure competition-based, the lead code that message 1 is sent is terminal device Oneself selection), base station cannot be distinguished these message 1 and come from the same terminal device or multiple terminal devices, because Lead code and running time-frequency resource are all.

Therefore, when base station using beam scanning receive message 1, receive identical 1 (message 1 of message from multiple reception wave beams In have identical running time-frequency resource and lead code) when, base station can not determine that these message 1 come from the same terminal device still Multiple terminal devices.As shown in Fig. 3 (a), base station is by receiving wave beam 1 and receive that wave beam 2 receives is that the same terminal is set The message 1 that standby (terminal device 1) is sent.As shown in Fig. 3 (b), base station is by receiving wave beam 1 with what reception wave beam 2 received The message 1 that different terminal equipment (terminal device 2 and terminal device 3) is sent.In both cases, if terminal device is again rigid Same lead code is used easily, and base station cannot be distinguished these message 1 and come from the same terminal device or multiple terminals Equipment.

In this case, it is common practice to which base station sends multiple message 2.Base station, which sends multiple message 2, can occupy one Fixed running time-frequency resource causes the occupancy and consumption of running time-frequency resource.

The embodiment of the present application provides a kind of communication means and equipment, to reduce in random access procedure because sending multiple message The occupancy and consumption of 2 pairs of running time-frequency resources.

It is located in the coverage area of a transmission wave beam of base station with terminal device 1 and terminal device 2 below, base station passes through The message that 1 receiving terminal apparatus 1 of wave beam is sent is received, the message sent by receiving 2 receiving terminal apparatus 2 of wave beam；And terminal Equipment 1 and terminal device 2 initiate to be illustrated for random access using identical lead code.It is appreciated that for three with On the implementation that is sent when carrying out random access in wave beam at one of base station of terminal device, be referred to the application implementation Two terminal devices of example send implementation when carrying out random access in wave beam at one of base station to realize, repeat no more.

Fig. 4 is the flow diagram that a kind of communication means provided by the embodiments of the present application is realized.As shown in figure 4, the side Method includes:

Step 101: respectively to the message 1 of base station transmission random access, base station connects respectively for terminal device 1 and terminal device 2 Receive the message 1 that terminal device 1 and terminal device 2 are sent；

Specifically, the message 1 for the random access that base station is sent by reception 1 receiving terminal apparatus 1 of wave beam, base station is by connecing Receive the message 1 for the random access that 2 receiving terminal apparatus 2 of wave beam is sent.

Step 102: base station measurement receives TA corresponding to used reception wave beam when each message 1, and judges to measure The difference of any two TA in obtained multiple TA；

If the difference of any two TA measured is greater than preset threshold value, the step 103A- step in Fig. 4 is executed 106A；If the difference of any two TA measured is less than preset threshold value, the step 103B- step 106B in Fig. 5 is executed.

The present embodiment is to be illustrated by taking two terminal devices as an example, such as terminal device 1 passes through the reception wave beam 1 of base station Message 1 is sent, then base station measurement receives the corresponding TA of wave beam 1, i.e., TA when terminal device 1 sends message 1 is TA1；Terminal is set Standby 2 send message 1 by the reception wave beam 2 of base station, then base station measurement receives the corresponding TA of wave beam 2, i.e. the transmission of terminal device 2 disappears TA when ceasing 1 is TA2.Whether the difference that TA1 and TA2 is compared in base station is greater than preset threshold value.

Step 103A: when the difference of any two TA in the multiple TA measured is greater than preset threshold value, base station is from described It selects a TA as the first TA in multiple TA, sends the message 2 of a random access, include described first in the message 2 TA；

When measurement, which obtains TA1 and TA2, is greater than preset threshold value, illustrate terminal device 1 and terminal device 2 and base station away from From gap it is larger.In this case, the message 2 that base station is sent, and a TA is only included in the message 2, i.e., it is described First TA.Because only sending the message 2 of a random access, without sending two different message 2, reduce random access mistake The occupancy and consumption of running time-frequency resource caused by message 2 in journey because sending multiple random access.It is appreciated that when terminal device When quantity is 3 or more, the running time-frequency resource for capableing of reduction can be more.

Optionally, when base station selected TA, it can choose the corresponding TA of the strongest reception wave beam of signal strength as described One TA.For example, receiving wave beam 1 and receiving in wave beam 2, the signal strength for receiving wave beam 1 is most strong, then the transmission of terminal device 1 disappears TA1 when ceasing 1 is as the first TA.The strongest reception wave beam of selection signal intensity, when can guarantee subsequent messaging Success rate, and then improve the success rate of random access, the high reliablity of random access.

Optionally, the strongest reception wave beam of base station selection signal, can be by measuring the letter received on each reception wave beam Number energy intensity, such as reference signal average energy intensity, to judge which receives the signal strength highest of wave beam.The ginseng Examining signal includes but is not limited to: demodulated reference signal (demodulation reference signal, DMRS) or SRS etc..

When specific implementation, base station sends the transmission wave beam used when message 2, is that terminal device is sent used in message 1 The corresponding transmission wave beam of running time-frequency resource.Since terminal device 1 and terminal device 2 are located at the covering model of a transmission wave beam of base station In enclosing, the message 2 that base station is sent, terminal device 1 and terminal device 2 can be received.

It should be noted that the threshold value in the embodiment of the present application can carry out different settings based on specific scene, this Application embodiment does not limit specific threshold value.As long as can effectively distinguish different terminal devices and meet the item of random access Part all can serve as threshold value described in the embodiment of the present application.

Step 104A: terminal device 1 and terminal device 2 send message 3 to base station respectively after receiving the message 2；

Terminal device 1 and terminal device 2 can carry described first obtained from the message 2 when sending message 3 TA.For example, including the first TA, the message 3 that terminal device 2 is sent to base station in the message 3 that terminal device 1 is sent to base station In also include the first TA.At this moment, the TA carried in the message 3 that terminal device 1 and terminal device 2 are sent be it is identical, all It is the first TA.

Step 105A: base station receives message 3 by reception wave beam corresponding to the first TA；

For example, the base station selected corresponding TA of wave beam 1 that receives is as the first TA 3 energy of message that then terminal device 1 is sent It is enough successfully received, the message 3 that terminal device 2 is sent will not be received.Terminal device 2 accesses in this random access procedure Failure can retransmit afterwards the message 1 of random access for a period of time with random back.

In this way, only TA terminal device identical with the first TA can just be successfully transmitted the message 3 of random access, it can The random access for limiting a terminal device is solved terminal device 1 and terminal device 2 while being initiated using identical lead code The problem of conflicting caused by random access.

Step 106A: base station sends the message 4 of random access to terminal device.

Base station can send the message 4 of random access to terminal device 1 based on the message 3 of the random access received.

If the difference of any two TA is less than preset threshold value in multiple TA that in a step 102, base station measures, then originally The method for applying for that embodiment provides is as shown in Figure 5.In Fig. 5, after executing step 101 and step 102, the method is also wrapped It includes:

Step 103B: when the difference of any two TA in the multiple TA measured is less than preset threshold value, base station determines the Two TA, and send the message 2 of a random access；It include that the 2nd TA and the transmission of instruction terminal equipment disappear in the message 2 The information of the number of breath 3.

Wherein, the 2nd TA can be base station according to preset rules, to the reception corresponding TA1 of wave beam 1 and receive wave beam 2 What corresponding TA2 was obtained according to preset rules.The preset rules include but is not limited to: take TA1 and TA2 average value or with it is flat The close value of mean value takes the TA of maximum value in TA1 and TA2, takes in TA1 and TA2 the TA of minimum value or signal strength is maximum connects Receive the corresponding TA of wave beam.

Optionally, the value of the 2nd TA is also possible to other values that can represent multiple TA, terminal device each in this way After receiving the 2nd TA in message 2, message 3 can be sent to base station and can send success.

Specifically, base station when sending message 2, be using terminal equipment send message 1 when running time-frequency resource corresponding to It sends wave beam and sends the message 2.Since terminal device 1 and terminal device 2 are located at the covering model of a transmission wave beam of base station In enclosing, when the transmission wave beam and terminal device 2 of the corresponding base station of running time-frequency resource when terminal device 1 sends message 1 send message 1 The corresponding base station of running time-frequency resource transmission wave beam it is identical.Therefore, terminal device 1 and terminal device 2 can receive base station The same message 2 sent.

Optionally, instruction terminal equipment in base station sends the number of message 3, is used when can receive message 1 according to base station The quantity of reception wave beam determine.For example, when base station instruction terminal equipment sends the number and base station reception message 1 of message 3 The used quantity for receiving wave beam is identical.In the present embodiment, base station passes through two different reception wave beams respectively and (receives wave beam 1 and receive wave beam 2) message 1 that receiving terminal apparatus 1 and terminal device 2 are sent, then indicate that terminal device is sent in message 2 The number of message 3 is 2 times.It is appreciated that when base station receives the message that N number of or M terminal device is sent by N number of reception wave beam When 1, the number that base station indicates that terminal device sends message 3 in message 2 is n times.Wherein, N and M is integer greater than 0, and M More than or equal to N.

Optionally, instruction terminal equipment in base station sends the number of message 3, can be in the message 2 by increasing one newly Field indicates, can also be indicated with existing field in multiplex message 2, the embodiment of the present application does not limit the side of base station instruction Formula.For example, the field that message 2 includes has in LTE: retransmitting the random back parameter field of message 1 (for calculating random return Move back the time), message 1 use random sequence id field (which message 1 that the message 2 is in response to recognized for terminal device), The word of TA field, ascending resource scheduling (UL-grant) field and the C-RNTI for receiving message 4 for sending message 3 Section.Base station can be further added by a field in message 2 and carry out the number that instruction terminal equipment sends message 3, can also be multiplexed weight Pass the random back parameter field of message 1, random sequence id field, TA field, UL-grant field and the C- that message 1 uses Any one of RNTI field carrys out the number that instruction terminal equipment sends message 3.

It optionally, can also include that instruction terminal equipment sends the running time-frequency resource used when message 3 every time in the message 2 Information.Base station indicates the number that terminal device sends message 3 in message 2, is to be able to receive all terminals and sets The message 3 that preparation is sent.In order to guarantee that all terminal devices can be successfully transmitted message 3, can be sent out every time with instruction terminal equipment Used running time-frequency resource when sending message 3.

Specifically, the instruction terminal equipment for including in the message 2 sends used running time-frequency resource when message 3 every time, It is the running time-frequency resource for having administrative relationships with the reception wave beam used when receiving message 1.For example, in the present embodiment, in the message 2 Including instruction terminal equipment send message 3 every time when used running time-frequency resource, be and receive in wave beam 1 and reception wave beam 2 A relevant running time-frequency resource.I.e. terminal device is according to use when each transmission message 3 indicated in the message 2 Running time-frequency resource send message 3 when, base station can by receive wave beam 1 or receive wave beam 2 receive.

Base station instruction terminal equipment sends used running time-frequency resource when message 3 every time can be different.Optionally, base station refers to Show that used running time-frequency resource when terminal device sends message 3 every time can be the running time-frequency resource on continuous T TI.

Step 104B: terminal device 1 and terminal device 2 are sent to base station respectively after receiving the same message 2 Message 3；

Terminal device 1 and terminal device 2 send message according to the number of the transmission message 3 indicated in the message 2 respectively 3.For example, the number that instruction sends message 3 in the message 2 is 2 times, then terminal device 1 sends message 3 twice, terminal device 2 Also message 3 twice are sent.

Optionally, when further including used when instruction terminal equipment sends message 3 every time in the message 2 that base station is sent When the information of frequency resource, terminal device 1 and terminal device 2 are respectively according to the instruction of message 2, in each transmission message 3 of instruction Running time-frequency resource on send message 3.

For example, the reception wave beam 1 of 1 respective base station of terminal device, the reception wave beam 2 of 2 respective base station of terminal device.Base station exists Instruction sends message 3 twice in the message 2 of transmission, and message 3 is sent on continuous two TTI.Then on first TTI, Terminal device 1 and terminal device 2 send a message 3 respectively；On second TTI, terminal device 1 and terminal device 2 are distinguished Send a message 3.

Also, terminal device can also carry the 2nd TA obtained from message 2 when sending message 3.For example, eventually It include the 2nd TA carried in the message 2 in the message 3 that end equipment 1 is sent to base station, terminal device 2 is sent to base station Message 3 in also include the 2nd TA that carries in the message 2.

Step 105B: the message 3 that base station receiving terminal apparatus 1 and terminal device 2 are sent；

Optionally, when base station send message 2 in further include the time-frequency used when instruction terminal equipment sends message 3 every time When the information of resource, base station receives message 3 on each corresponding running time-frequency resource.

For example, the reception wave beam 1 of 1 respective base station of terminal device, 2 respective base station of terminal device receives wave beam 2；Base station is sent Message 2 in transmission message 3 of the instruction on continuous two TTI, terminal device 1 and terminal device 2 are respectively continuous two Message 3 is sent on a TTI.Then on first TTI, base station can receive disappearing for the transmission of terminal device 1 by receiving wave beam 1 Breath 3.On second TTI, base station can receive the message 3 of the transmission of terminal device 2 by receiving wave beam 2.

In this way, base station can receive the message 3 that terminal device 1 and terminal device 2 are sent by two reception wave beams.Energy Enough solve the problems, such as that base station can not receive the message 3 that multiple terminal devices are sent from the different wave beams that receives simultaneously.Base station can be with By way of the time-division, the message 3 that all terminal devices are sent is received.

Step 106B: base station sends message 4 to terminal device.

Specifically, base station can judge that these message 3 come from a terminal device still by the message 3 received Multiple terminal devices.For example, base station can be an end according to the ID of the terminal device carried in the message 3 received, judgement The message 3 that the message 3 or multiple terminal devices that end equipment is sent are sent.

If the message 3 received, from a terminal device, base station only sends a message 4.

Disappear if the message 3 received from multiple terminal devices, needs to send one to each terminal device Breath 4.Such as base station can send different message 4 in different times respectively.Each terminal device is after receiving message 4 Judge whether the ID for including in the message 4 received is identical as the ID of oneself.If the same the message 4 is received, if different The message 4 is then abandoned, and continues to listen to control channel to receive message 4.Until the ID for including in the message 4 that receives whether with The ID of oneself is identical, illustrates that the message 4 received is destined to oneself, then does not continue to receive message 4；Or random access Timer expired is competed, message 4 is received and fails, no longer reception message 4.

It include a TA (described second in the message 2 since in step 103B, base station only has sent a message 2 TA), section terminating equipment or all terminal devices is caused although to successfully transmit message 3, but in the message 3 of its transmission The endless total correctness of TA value, therefore base station needs to send correct TA to the incorrect terminal device of TA by message 4.Meanwhile base It stands and only specifies an interim C-RNTI in the message 2, and each terminal device needs possess after random access Unique C-RNTI in cell.So only one terminal device can continue to use the interim C-RNTI as formal C- RNTI, remaining terminal device are required to be designated C-RNTI again.Therefore, base station needs to carry amendment in the message 4 of transmission C-RNTI.

In order to make each terminal device that can successfully complete random access, base station needs to carry in the message 4 of transmission Modified TA and C-RNTI, such as modified TA and C-RNTI can be carried by two fields.

Optionally, base station can increase two fields newly to carry modified TA and C-RNTI in message 4, can also be direct Modifying existing TA and C-RNTI field is revised TA and C-RNTI, can also be multiplexed existing field and carry modified TA And C-RNTI.

For increasing by two modified TA and C-RNTI of fields carrying in message 4 by base station below, to base station by disappearing Breath 4 sends modified TA and C-RNTI to terminal device and is illustrated.

Amendment about TA: base station first judge the TA that measures when receiving message 3 whether with the TA phase that is carried in the message 3 Together.The TA that terminal device carries in message 3 is the 2nd TA, and it is that each terminal is set that base station, which receives the TA measured when message 3, Preparation specific TA when sending message 3.If the two is different, it is necessary to correct TA.I.e. base station is by the TA's measured when receiving message 3 It is worth the value of the modified TA as the terminal device, and increases a field in message 4, the field is for recording the amendment TA value.

Amendment about C-RNTI: when base station, determination has multiple terminal devices when carrying out random access, only one end End equipment can continue to use the interim C-RNTI, not need amendment C-RNTI；For other terminal devices, what base station was sent disappears Modified C-RNTI is carried in breath 4, to guarantee that each terminal device has a unique C-RNTI.

After each terminal device receives the message 4 of base station transmission, elder generation is judged whether according to the ID carried in message 4 and oneself ID it is identical.If identical, confirm that the message 4 is destined to oneself, then reads the TA field increased newly in message 4 and C- RNTI field.

Optionally, if terminal device from the value that TA field or C-RNTI field are read be specific value (e.g. full 0), It then indicates not needing amendment TA or C-RNTI, terminal device can continue to use the TA or C- carried in the message 2 received RNTI.If terminal device is not specifically to be worth from the value that TA field or C-RNTI field are read, terminal device obtains the two The content of field, and to update its TA and C-RNTI.

In this way, base station may be implemented multiple terminal devices random access simultaneously, can keep away by only sending a message 2 Exempt from the waste of running time-frequency resource caused by sending multiple message 2, and solves multiple terminal devices and use identical running time-frequency resource With lead code send message 1 when caused by random access collision the problem of.

What above-described embodiment was illustrated by taking the random access that two terminal devices are initiated as an example.When the end for having 3 or more End equipment is in the coverage area of one of base station transmission wave beam, and when sending message 1 using identical random access lead code, There may be 3 or more different TA.For example, there is 5 different TA after base station measurement, the difference of two of them TA is greater than pre- If threshold value, the difference of three TA is less than preset threshold value.In this case, base station can be greater than preset threshold to difference Terminal device corresponding to TA is realized referring to the implementation of above-mentioned steps 103A- step 106A；Default threshold is less than to difference Terminal device corresponding to the TA of value is realized referring to the implementation of above-mentioned steps 103B- step 106B.It repeats no more.
