In embodiment, uplink of 100 use space filter of the network node separation from multiple user nodes 110 passes It is defeated.This can be realized for example, by Buttler matrix.Same radio resource point is selected in two or more user nodes In the case where carrying out uplink, fallen into the different spaces wave beam for receiving Buttler matrix in view of user node 110, net Network node 100 can separate the transmission of these user nodes.However, will not then be sent to user node 110 in case of conflicting Response.Such spatial filter reduces has selected same wireless money in two or more user nodes 110 by chance Collision probability in the case where the distribution of source.

In embodiment, uplink 308 further includes response instruction.Response indicates to indicate user's section to network node 100 110 expectation network nodes 100 of point make response to uplink to user node 110.Such as based on payload data to be sent Type, user node 110 may determine whether in uplink include response indicate.For example, if user node 110 is fixed Phase (for example, once per second transmission) sends sensing data to network node 100, because most of uplink can be by network section Point 100 receives, if that some uplink are also not related without correctly reaching network node 100.Therefore, Yong Hujie Point 110 can determine not indicate in uplink using response.In another embodiment, if user node 110 is sent only Lotus data and key are that each uplink will reach network node 100, then user node 110 can activate uplink to pass Response instruction in defeated, to receive the response to its uplink.

If including that response indicates in uplink 308, network node 100 can send to user node 110 and answer Answer 310.In embodiment, network node 100 knows which radio resource allocation has been used in uplink 308.This is wirelessly provided Source distribution can for example be identified by temporary identifier.For example, provide to be stored with the time window for connectionless transport, subcarrier and The index of the reference of the data of at least one of code can be used as temporary identifier.In another embodiment, data entry can To include individual temporary identifier.For example, the data entry #3 in data can be associated with temporary identifier #70.Network Node 100 can then scramble response with casual user's node identifier.

In embodiment, two or more user nodes 110 be might have and select same radio resource allocation simultaneously And the transmission success of these user nodes.This also means that above-mentioned uplink is related to same casual user's node identifier. However, precoder is different, therefore interference can be ignored (if any).Therefore, it is marked through same casual user Each user node 110 will be sent to by knowing the scrambled response of symbol.If there is conflict, then it will not send and answer to user node 110 It answers.

When uplink 308 is successfully decoded in network node 100, it can be forwarded the transmitting uplink data being successfully decoded It is further processed to other network elements.

In embodiment, response instruction can indicate expectation uplink by another network element (except network node 100) Response.For example, response entity can be the end-to-end transmission that reception includes one or more packets in uplink transmission Final receiver.Response then can be sent back to user node 102 via network node 100 by the final receiver.

Fig. 4 A is the flow chart for showing its operation executed when user node 110 will send data.Show shown in Fig. 4 A Example and its description are assumed that user node 110 previously has received as shown in Fig. 2A, Fig. 2 B, Fig. 3 and its description and are come The first broadcast and the second broadcast of automatic network node 100.Second broadcast includes at least one nothing that mark is used for connectionless transport The data of line resource allocation.The data for identifying at least one radio resource allocation may include realize one group of connectionless transport must Want information.Alternatively, the data for identifying at least one radio resource allocation include at least one index, at least one above-mentioned index is mentioned For the reference of the data to the multiple necessary informations for being stored with realization connectionless transport.Above-mentioned necessary information may include for nothing Connect time window, subcarrier and the code of transmission.

Although in addition, Fig. 4 A and its description shown in example may teach timer (authorization validity timer or Back off timer (back-off timer)) to 0, but in other embodiments, timer can arrive in timing upwards for timing downwards Specific terminal.Timer can also be progression timer (progressivetimer).

The process starts from 400.402, user node 110 determines that it has payload data needs to send via uplink To network node 100.

User node 110 then determines if to want to receive the response to sent uplink 404.If The determination of user node 110 does not need response, then selects radio resource allocation 406.In Figure 4 A, term " authorization " is used to indicate The identical meaning with " radio resource allocation ".Execute at least one radio resource allocation that the data from the second broadcast are identified Middle selection radio resource allocation.

Upon selection, the unique identifier of user node 110 and payload data are included by user node 110 408 Next uplink opportunity is waited in one or more data packets to be sent, and 410.412, user node 110 makes Uplink packet is sent to network node 100 with selected radio resource allocation.

If the determination of user node 110 needs response, radio resource allocation is selected 414.It executes from the second broadcast At least one radio resource allocation for being identified of data in select radio resource allocation.Radio resource allocation can from have than It is selected in one group of specific radio resource allocation of the longer available time of other radio resource allocations.The group is specifically wireless Resource allocation is properly termed as semi-static radio resource allocation.The validity of these radio resource allocations passes through authorization validity timing Device (or radio resource allocation validity timer) Lai Dingyi, the authorization validity timer have in one section of longer time Effect, including discontinuous reception (discontinuous reception, DRX)/discontinuous transmission (discontinuous Transmission, DTX) period.Authorize one or more values of validity timer can be in user node 110 from network section It is defined in 100 received system informations of point.Such semi-static radio resource allocation is for example useful for ultralow time delay communication , because user node 110 withouts waiting for the radio resource allocation of broadcast.It can also be that network node 100 already ensures that this The semi-static radio resource allocation of sample will not conflict with other connectionless transports (by properly dispatching such resource).

When semi-static radio resource allocation has been chosen to for example be randomly assigned, user node 110 is awarded in 416 startings It weighs validity timer (it is referred to as radio resource allocation validity timer).Starting authorization validity timer it Afterwards, the unique identifier of user node 110 and payload data are included in one or more to be sent 408 by user node In data packet, and next uplink opportunity is waited 420.422, user node 110 uses selected radio resource point Orientation network node 100 sends uplink packet.

If receiving response 424 before authorization validity timer expires, user node 110 can determine net Network node 100 has been properly received uplink, and the process ends at 432.

If being not received by response 424, validity timer is authorized to update 428.In the updated, user node 110 check whether authorization validity timer expires 430.If authorization validity timer expires not yet, user Node 110 waited for 420 uplink opportunitys next time.When use and the authorization associated semi-static radio resource of validity timer When distribution, if being not received by response and validity timer being authorized not expire, same radio resource can be reused Distribution.

In embodiment, when 424 determine and are not received by response, additional timer can be used: keeping out of the way timing Device.The value of back off timer can be closed according to the system information broadcasted from the first broadcast or from the radio resource allocation of selection The parameter of the gain of parameter of connection randomly chooses.When 426 back off timer expire and 430 authorization validity timers also When not expiring, user node 110 waits next uplink opportunity 420, and reuses the wireless money for previously selecting and using Source distribution.

If expired in 430 authorization validity timers, there are two selections for user node 110.It may proceed to It selects the process of new radio resource allocation (" authorization ") and starts again at uplink process using new radio resource allocation. In embodiment, if the unsuccessful re-transmission that user node 110 performs pre-determined number is attempted, user node can go to it His transfer program 432 for example, going to the channel based on contention to send upstream data, or goes to request and establishes for data The carrying of communication and network registry.

Fig. 4 B shows the flow chart that retransmission timer is used at user node 110.Although institute in Fig. 4 B and its description The example shown can illustrate the downward timing of retransmission timer to 0, but in other embodiments, and timer can arrive in timing upwards Specific terminal.The retransmission timer can also be progression timer.

As previously mentioned, network node 100 can broadcast in the system information of the first broadcast to be used by user node 110 Default retransmission timer.Although having shown that it wants to be apprised of its uplink quilt with response instruction in user node 110 Be successfully decoded but still without response is received from network node 100 in the case where, retransmission timer trigger user node 110 at Movement.

The process starts from 440 when transmitting timer starting.When selection radio resource allocation or work as selected by transmission use When the uplink for the radio resource allocation selected, retransmission timer starting.444, it is determined whether receive to uplink Response.If response has been received, retransmission timer is reset 446, and the process terminates 452.

If being not received by response 444 and not expiring in 448 retransmission timers, which is circulated back to 442 reduce the value of retransmission timer, and check whether 444 and receive response.

If 448 before receiving response retransmission timer expire, user node 110 can go to following several Possible item:

1. user node 110 can decode the broadcast message for new connectionless radio resource allocation.

2. user node 110 can increase the transmission power of next transmission, next phase transmission use and previously selected Same radio resource allocation.

3. user node 110 can go to 450 based on the channel of contention to send upstream data.

4. user node 110 can request carrying and network registry of 450 foundation for data communication.

In embodiment, because the first two selection avoids the alternative solution for using and such as time delay being caused to dramatically increase, because This is preferred.

Exemplary difference shown in Fig. 6 A and Fig. 6 B is, in the example shown in Fig. 6 A, spread spectrum is used in uplink Code, and in the example shown in Fig. 6 B, use frequency band when non-overlap.Therefore, in the example shown in Fig. 6 B, code sequence is not used Column are spread to data and are sent the coded sequence for channel estimation, but can non-overlap when frequency band in send Uplink, and send lead code 618 rather than transmission coded sequence that user node 110 and network node 100 are both known about.

Fig. 7 A shows the solution according to the embodiment that beam forming is carried out to radio resource allocation.

In order to minimize the conflict of the uplink from user node to network node, and in order to introduce dynamic resource allocation A possibility that with scheduling, shown in example and its description as shown in Figure 7 A, network node 100 can be carried out radio resource allocation Beam forming.

Wave beam can be designed by way of the aerial array and ambient enviroment of any suitable network node 100.Downlink Wave beam can be for example equally divided into as shown in the example of Fig. 7 A 45 degree of sectors or be directed toward anticipating user where geographic area. Example shown in Fig. 7 A shows the downlink transfer of radio resource allocation, and wherein the transmitting of network node 100 is with radio resource point 8 wave beams of the different subcarrier distribution matched.This means that each wave beam includes one group of different radio resource allocation.

In embodiment, the radio resource allocation of precoding can be reused by adjacent network node.However, dry in order to reduce Probability is disturbed, and has two wave beams of same wireless resource allocation towards the same space region, network section in order to avoid being formed Point 100 can be randomized the subcarrier distribution of radio resource allocation.

Fig. 7 B shows the solution that field angle is randomized when carrying out beam forming to radio resource allocation.

Example shown in Fig. 7 B is with example difference shown in Fig. 7 A, in the example shown in Fig. 7 B, random offset 702 It is applied between random access window and differently wave beam is turned to, avoid and interfere between network node.

In addition, also being helped in the solution shown in Fig. 7 A and Fig. 7 B using beamformed radio resource allocation It is transmitted in receiving actual uplink at network node 100.After broadcasting beamformed radio resource allocation, user is come from The uplink of node 110 can be received with receiving filter, and the receiving filter is from the transmission for radio resource allocation The export of precoding weight vector.In addition, can be used from the response (if necessary) that network node 100 is sent to user node 110 Identical precoding weight vector is transmitted with initial radio resource distribution.

In the exemplary embodiment shown in Fig. 7 A and/or Fig. 7 B, beam forming is also used to from network node 100 to user Node 110 sends response.If network node 100 is properly received uplink and user node 110 in the uplink It include response instruction, then network node 100 can send beamformed response to user node 110, and this is answered Answering can be scrambled with the associated temporary identifier of used radio resource allocation.For being sent to user node 110 The wave beam of response can be identical as receiving the wave beam of Buttler matrix of uplink from user node 110.

Further to example shown in Fig. 7 A and Fig. 7 B, by beam forming, mobile network can spatially optimize Resource distributes the resource of optimal number for specific geographical area.Therefore, can to need more resources geographic area distribute more More resources (for example, radio resource allocation).In addition, the received uplink by using for reference, can also spatially optimize Used modulation and coding strategy realize ideal Block Error Rate.

In embodiment, access grade corresponds to the respective service quality or priority of application or service.User node 110 reads second Access grade information in broadcast is to determine if to can be used the transmission that authorization carries out service needed for it.User node 110 The predefined mapping between (multiple) services and (multiple) access grade can be being stored in memory 116.In another embodiment In, which can match in the subscriber identification module (subscriber identity module, SIM) of user node 110 It sets.In another embodiment, user node 110 can by other means, for example, Non-Access Stratum (non-access Stratum, NAS) signaling or chain of command configuration, above-mentioned mapping is received from mobile network in advance.For given access grade, In simplest situation, access information can indicate specific radio resource allocation can with or may not be usable for the access grade The transmission of service.

In another embodiment, the access grade information of access grade can indicate that radio resource allocation can be used for this and connect Enter the particular probability of the transmission of grade.For example, the processor 112 of user node 110 can be used for taking out between one 0 to 1 with Machine number simultaneously compares the probability whether it is lower than instruction.If it is, resource allocation, which can be used, in user node 110 carries out uplink biography It is defeated.The advantage of doing so is that being changed by the conflict between the uplink using previous radio resource allocation arrived according to the observation Become the probability indicated in access grade information, very high efficiency may be implemented in network.Spatially due to radio resource allocation Distribution, this can be used to inefficient caused by being avoided because of crowded point overload.

In embodiment, access grade information may include that user node 110 is being attempted to access network again to carry out together The duration for needing to wait before the uplink of one access grade.Access grade information in radio resource allocation can be as follows Table:

Access probability grade 1	Waiting time grade 1
		Access probability grade 2	Waiting time grade 2
…	…
		Access probability grade M	Waiting time grade N

Above- mentioned information can be encoded in an efficient way, for example, the quantity of probability and waiting time are limited to Several ranks.

In embodiment, access grade information can indicate whether radio resource allocation can be used for signaling and/or payload Data transmission.In another embodiment, access grade information, which also can indicate that, only allows certain types of signaling to use wireless money Source distribution.

In embodiment, access grade information also can indicate that whether access obstruction is applied to it belongs to public land shifting Move the user node in network (public land mobile network, PLMN), and/or the user in the PLMN accessed Node, and/or the user node for being connected to particular core net or core net slice.
