In LTE system, once the case where RRC is reconfigured has occurred, then in the fuzzy phase, the same terminal is set Standby, the network equipment is both had been friends in the past nID(i.e. RRC reconfigures the n of the RRC signaling carrying before signalingID) there is new n againID(；That is RRC reconfiguration The n carried in confidence orderID), then the previous common way of mesh is that the network equipment is alternately based on old nIDWith new nIDFor adding Disturb downlink data, such as the old n of odd-times transmissionID, the new n of even-times transmissionIDOr it is on the contrary.This mode is more simple It is single, but it is once transmitted as failed transmission due to inevitable, so there is the wasting of resources.
It is that n is replaced using cell ID (CellID) in the fuzzy phase there are also a kind of schemeIDFor initializing scramble sequence Generator, i.e. nIDAlthough=CellID, this method avoid the ambiguity of sending and receiving end, but also have at least two disadvantages: 1) in mould The paste phase and fuzzy need to convert three different n around phaseID, so that the generation of scramble sequence becomes complex；2) fuzzy Before phase terminates, it is necessary to all scrambled using CellID, it in this case can only be using more conservative Downlink Control Information (DCI) lattice Formula, such as format 1_0, this style representatives is more conservative transmission mode, and the data flow that can be supported is fewer, generally Be necessary to ensure that connection status but it is of less demanding to efficiency of transmission in the case where use, also therefore can reduce scheduling flexibility and Frequency spectrum service efficiency.The definition of specific DCI format may refer to 3GPP TS38.212v15.0.0 (3rd Generation Partner Project Technical Specification 38.212)。
The application provides a kind of method, can realize flexible dispatching as early as possible, improves efficiency of transmission.
Fig. 2 is the illustrative method of a data transmission within the fuzzy phase, without loss of generality, with the shared letter of physical down Specific as follows for road (physical downlink shared channel, PDSCH) transmission, wherein the initial value of i is 0, separately Outside, nIDIt is also an example of high-rise configuration parameter, the other similar high-rise configuration parameter for having the fuzzy phase can also use this The way of sample:
Step S210: the network equipment is in i-th transmission with old nIDThe RRC of ----i.e. reconfigure signaling (such as RRCreconfig the n that the RRC signaling before) carriesID--- --- generates scramble sequence, wherein without loss of generality, RRC is reconfigured RRC signaling before signaling is the last RRC signaling；
Step S220: the network equipment receives the data receiving feedback signals from terminal device:
If data receiving feedback signals are to indicate to receive correct ACK, return step S210, what is transmitted next time When still with old nIDGenerate scramble sequence；
If data receiving feedback signals are to indicate to receive incorrect NACK, enter step when transmit next time Rapid S230 switches nID；
Step S230: the network equipment is in current transmission with new nID(i.e. RRC reconfigures the n of signaling carryingID) generate scrambling Sequence；
Step S240: the network equipment receives the data receiving feedback signals from terminal device,
Incorrect NACK is received if it is expression, and did not also receive passed for the downlink based on new nID before Defeated ack signal indicates to receive correctly, then enters step S210, with old n when transmit next timeIDGenerate scrambling sequence Column；
If it is the correct ACK of reception is indicated, then show that terminal device has been detected by new nID, then step can be entered Rapid S250, transmission later can be directly based upon new nIDGenerate scramble sequence, it is no longer necessary to old nID, in other words, it is equivalent to nID Be reconfigured successfully, without until terminal device send show successful signaling (such as RRCreconfigCompleted) is reconfigured New n can be appliedID.
Step S250: since current transmission, the network equipment is based on new nIDGeneration scramble sequence, DCI format aspect, in addition to Except the more conservative format 1_0 routinely used in the fuzzy phase, can also in other words it be mentioned using others format such as 1_1 The high flexibility of scheduling, increases frequency spectrum service efficiency.
In addition, after the network equipment receives the RRCreconfigCompleted signaling of terminal device transmission, then it is necessary Switch to new nIDScramble sequence is generated to scramble downlink data and send.
Step shown in Fig. 2 is the behavior of the network equipment, and the behavior of terminal device can illustratively be provided by Fig. 3, can To see, dotted arrow indicates that terminal device successfully solves new n from RRCreconfig signaling in figureIDAt the time of, this is because After receiving RRCreconfig signaling other than the physical layer process delay such as decoding demodulation, also for the interpretation of signaling information Delay, therefore this really solves new nIDAt the time of necessarily after receiving RRCreconfig signaling, due to different terminals Equipment disposal ability is also different, therefore this delay is also different for different terminal devices.Preceding terminal is set at this moment For with old nIDGenerating scrambling sequence, (scrambling sequence is identical as scramble sequence, is intended merely to distinguish transmitting terminal and receiving end, transmitting terminal Illustrated with scramble sequence, receiving end is illustrated with scrambling sequence), after this then with new nIDScrambling sequence is generated, alternatively, terminal is set It is standby any time between the moment and transmission RRCreconfigCompleted signaling to use new n insteadIDGenerate descrambling Sequence, but should be noted that and once change into new nIDIt afterwards, cannot be again with old nIDGenerate scrambling sequence.It is opposite with transmitting terminal It answers, with old nIDWhen, DCI format may only have 1_0, and apply new nIDLater, as long as after detection is correct primary, It can be using the format 1_1 in other DCI formats, such as Fig. 3 that can support more data flow more kept forging ahead.
In addition, as seen from Figure 3, if UE solves new nIDAfterwards, RRCreconfigCompleted letter can be sent immediately It enables, then the beneficial effect of this programme is than relatively limited, but in view of RRCreconfigCompleted itself is a high-level signaling, The either formation of the signaling or the reception of network equipment detection, when all not accomplishing instantaneously to receive, therefore necessarily having a here Between it is poor, only the processing capacity of different terminal equipment is different or RRCreconfigCompleted needs the information for including different This time difference is caused to have with short, this programme is exactly to make full use of the time difference, utilizes new n as early as possibleID, so as to more flexible Scheduling.
It can be seen that new n can be gone to as early as possible using the method in the applicationID, so as to use a variety of DCI formats, obtain The flexibility that must be dispatched, and two kinds of n are related only in entire reconfiguration courseID, more succinctly.Even if poor in channel condition When, it is possible to it can be in new nIDWith old nIDBetween toggle, but this also only returns to processing in LTE as previously described Mode, therefore still have stronger practicability.
Physical Uplink Shared Channel (physical uplink shared channel, PUSCH) is transmitted, processing side Formula is similar with the PDSCH transmission of downlink.For terminal device, new n is being detectedIDBefore, with old nIDIt is right after generation scramble sequence Upstream data scrambling retransmits, and is detecting new nIDLater, with new nIDIt generates after scramble sequence scrambles upstream data and sends out again It send.And for the network equipment, the network equipment is still with old n at the beginning of the fuzzy phaseIDDetection, always with old if correct nIDDetection, can be again with new n in view of the processing capacity of the network equipment is stronger if incorrectIDDetection one time, works as network Equipment is with new nIDAfter correct detection, then old n is abandonedID, only with new nID, and start by new nIDScheduling.
In fact, can also have other similar embodiment, and such as: 1) in fuzzy phase it is all based on old nIDGenerate scrambling sequence Column, certainly, can only also use DCI format 1_0 under this mode；2) new n is all based in the fuzzy phaseIDGenerate scramble sequence, but this It will lead under kind mode and detect new n in terminal deviceIDTransmission before is all wasted；3) an extreme mode be in order to It avoids confusion, does not dispatch the terminal device reconfigured within the fuzzy phase, certainly, this mode is more to the waste of resource.
In addition, with old n when i=0 in example shown in Fig. 2IDStart, but in fact can also be with new nIDStart, especially When delay dispatching, i.e. at the time of i=0 after RRCreconfig signaling for some time, the network equipment It can be directly with new nIDIt attempts to send, i.e., is executed since the step S230 of Fig. 2, but the behavior of terminal does not change.
Fig. 4 gives a specific example, it is assumed that old nIDIt is 99, new nIDIt is 100, the terminal device inspection within the fuzzy phase Measure new nIDAt the time of be T0, moment T1, T2, T3 are before T0, and moment T4, T5, T6 are before T0, then an illustrative place It is as follows to manage process:
Moment T1: the network equipment is with nID=99 generation scramble sequences scramble downlink data and send, DCI format 1_0 Terminal device is with nID=99 detections are correct, feeding back ACK；
Moment T2: the network equipment is still with nID=99 generation scramble sequences scramble downlink data and send, DCI format 1_ 0, terminal device nID=99 cannot detect correct, feedback NACK；
Moment T3: the network equipment is with nID=100 generation scramble sequences scramble downlink data and send, DCI format 1_ 0, terminal device nID=99 cannot detect correct, feedback NACK；
Moment T4: the network equipment is with nID=99 generation scramble sequences scramble downlink data and send, DCI format 1_0, Terminal device nID=100 cannot detect correct, feedback NACK；
Moment T5: the network equipment is with nID=100 generation scramble sequences scramble downlink data and send, DCI format 1_ 0, terminal device nID=100 detections are correct, feeding back ACK；Then since the next moment, with nID=100 generate scrambling or descrambling Sequence.
Moment T6: the network equipment is with nID=100 generation scramble sequences scramble downlink data and send, DCI format 1_ 1, terminal device nID=100 detections are correct, feeding back ACK.
N is adjusted according to ack/nack signal to the embodiment of the present application aboveIDThe method for generating scramble sequence has been made in detail It introduces.Using n provided by the embodiments of the present applicationIDThe flexibility of data transmission can be improved in the method for adjustment.
It is the solution of scramble sequence part in the data transmission for downlink or uplink above, in fact, in channel In the generation of reference signal (channel state information reference signal, CSI-RS) sequence, also can Use nID, therefore the method in the application can also be used, usage is the same, not reinflated here.
In addition, demodulated reference signal (the demodulation during reconfiguring, for PDSCH and PUSCH Reference signal, DMRS) producing method also have similarly fuzzy phase problem with the producing method of scramble sequence.Such as The generator of the sequence of DMRS initializes (3GPP TS38.211v15.0.0 (3 by following formulard Generation Partner Project Technical Specification 38.211):
Wherein cinitIt is the DMRS sequence initialization factor, l is the serial number of OFDM symbol inside time slot, nsIt is the time slot in frame Serial number,It is configurable parameter, value range isBy high-level signaling parameter UL-DMRS- Scrambling-ID (when being used for uplink) or DL-DMRS-Scrambling-ID (when being used for downlink) are determined, nSCID∈ 0, 1}.It can be seen that when RRC is reconfigured,Similarly there is the problem of fuzzy phase, i.e., also has newWith it is oldIt exists simultaneously, so processing mode and nIDProcessing mode it is completely the same, method involved in above-described embodiment is complete It can apply, i.e., be adjusted according to the ACK/NACK of terminal device feedback using newWith it is oldHere no longer superfluous It states.
On the other hand, for the occasion that other need RRC to be reconfigured, such as when switching, new and old mark is equally had The problem of (Identity, ID) is existed simultaneously namely the presence for equally having the fuzzy phase, in this case, the aforementioned implementation of the application The method of example is equally applicable, and the network equipment first reattempts new ID using old ID after NACK or first using new ID Old ID is reattempted after NACK, according to flow processing shown in Fig. 2, and terminal device similarly can not solve newly ID before use old ID, solve after new ID with regard to new ID, principle is completely the same.It repeats no more.
