Description

Information transferring method and device based on carrier wave polymerization

Technical field

The present invention relates in carrier aggregation system the information transmission technology more particularly to it is a kind of based on carrier wave polymerization information Transmission method and device.

Background technology

Advanced long-term evolution system (LTE-Advanced, Long Term Evolution Advance) is that the third generation closes Make Partnership Program (3GPP, the 3rd Generation Partner Project) tissue to meet International Telecommunication Union (ITU, International Telecommunication Union), advanced world mobile communication (IMT-Advanced, International Mobile Telecommunication-Advanced) requirement and the standard released.LTE- Advanced systems are an evolution versions on the basis of long evolving system (LTE, Long Term Evolution), Many new technologies are introduced to meet the primary demand of IMT-Advanced, one technology of most important one is exactly that carrier wave is poly- It closes.

Due to the property in short supply of current radio spectrum resources, the frequency spectrum resource that each mobile operator in the world possesses often compares zero It dissipates, and IMT-Advanced requires the index higher of peak rate (to support 100Mbps under high mobility, supported under Hypomobility 1Gbps), IMT-Advanced requirements cannot be satisfied with the bandwidth of current LTE standard maximum 20MHz, so needing to expand It is charged to more high bandwidth, such as 40MHz, 60MHz, it is even higher.One of the method for improving bandwidth and peak rate be to frequency domain into Row expands, such as several LTE frequency bands based on 20MHz are carried out bandwidth expansion by way of " carrier wave polymerization ", and here it is loads The essence of wave polymerization technique.Therefore, LTE-Advanced systems also belong to multicarrier system.

In the LTE-Advanced systems for applying carrier aggregation technology, the carrier wave for participating in polymerization is referred to as component carrier (Component Carrier), user equipment (User Equipment, referred to as UE) can be simultaneously on multiple component carriers Transmitting-receiving transmission is carried out with eNB.Component carrier can use LTE defined frequency ranges, and it is LTE-Advanced that can also use Specially newly-increased frequency range.Based on current frequency spectrum resource anxiety, it is impossible to always there is continuous component carrier on frequency domain that can distribute to Operator uses, therefore component carrier can be continuous on frequency band, can also be discontinuous.

It, can be there are one first carrier and one or more for some user equipment in carrier aggregation system A second carrier wave.First carrier is generally main carrier wave, can be mainly used for carrying number with carrier signaling and data, the second carrier wave According to can also bearing part signaling.Carrier wave can be divided into up-link carrier (being communicated for user equipment to control station) and downlink carries Wave (communicates) for control station to user equipment.The wireless service areas of corresponding first carrier is first service area, and corresponding second carries The wireless service areas of wave is second service area.In different systems, first carrier, first service area and the second carrier wave, second The concept and title of service area can all have corresponding details to define.

Such as in LTE/LTE-A systems, being configured with the user equipment that carrier wave polymerize, only there are one radio resources in net Manage (RRC, Radio Resource Control) connection.Wireless resource management connection establishes/re-establishing/and switches generation When, NAI mobile messages are provided and the service area inputted safely (Serving Cell) be referred to as main plot (Primary Cell, PCell), i.e. first service area, and according to UE capability configuration can configure one or more secondary cell (SCell, Secondary Cell), i.e. second service area.Further, the corresponding carrier wave in main plot is exactly main carrier, including for Downlink principal component carrier wave (DL PCC, the Downlink Primary Component that control station is transmitted to customer equipment data Carrier uplink principal component carrier wave (UL PCC, the Uplink Primary) and for user equipment to control station number communicated Component Carrier).Similar, the corresponding carrier wave of secondary cell is exactly auxiliary small carrier wave, wherein is arrived including being used for control station The downlink auxiliary component carrier (DL SCC, Downlink Secondary Component Carrier) of customer equipment data transmission With uplink auxiliary component carrier (UL SCC, the Uplink Secondary communicated for user equipment to control station data Component Carrier)。

In LTE system, in order to realize and keep the uplink synchronous between user equipment and base station, base station according to base station with Propagation delay time sending time lead (TA, Timing Advance) between each user equipment gives each user equipment, Yong Hushe The standby Timing Advance sent according to base station shifts to an earlier date or postpones the opportunity of respective uplink, to make up in user UE to base station Propagation delay time so that the uplink signal of different user devices all reaches base station within the reception window of base station.

It is that UE is configured with a uplink to obtain and keep the uplink synchronous between UE and base station, base station in LTE system Synchro timer (TAT, Time Alignment Timer), if UE can receive base station before TAT time-out is sent to UE's Timing Advance, then it is assumed that uplink synchronous is kept between the UE and the base station, otherwise TAT time-out, UE think to lose uplink synchronous. In non-synchronous regime or desynchronizing state, UE obtains the uplink synchronous between base station by random access procedure, and UE is received After the random access response (RAR, Random Access Response) that base station is sent, start timer TAT, and according to base station The Timing Advance carried in random access response shifts to an earlier date or postpones the opportunity of uplink.UE obtains same with the uplink of base station After step, during TAT is run, if receiving the TA orders (TA command) that base station is sent to UE, TAT is restarted, and use The Timing Advance carried in TA orders is in advance or postponement uplink transmission time, UE think that oneself continuation and base station keep uplink same Step；If UE is not received by TA orders, i.e. TAT time-out during TAT is run, UE thinks that oneself loses uplink with base station It is synchronous, all uplink and downlink resources for being dynamically assigned to the UE are deleted, all uplinks mixed self-adapting to be sent is emptied and retransmits and delay Area (HARQ buffer) data are rushed, notice wireless heterogeneous networks (RRC, Radio Resource Control) sublayer discharges Static state/semi-static ascending physical signal resource of the UE is distributed to, hereafter if there is upstream data needs to send or has downlink data to need It receives, UE is required for carrying out random access first to regain uplink synchronous.

After introducing carrier wave polymerization, user equipment may be simultaneously operated on multiple component carriers, these component carriers are in frequency Taking can be continuous, and can also be discontinuous；Can in identical frequency band, may also come from different frequency bands. The case where different frequency bands are come from for the discontinuous situation of component carrier or component carrier, since each component carrier has Different transmission characteristics, the Timing Advance on each component carrier may be different；Even if each component carrier belongs to same frequency Band and continuous on frequency band, if each component carrier is originated from different Remote Radio Unit (RRU, Remote Radio Unit), Or in order to increase MPS process, each component carrier is handled via different repeaters (repeater) respectively, then each component carries Timing Advance on wave may also be different.In LTE system, UE is only operated on a carrier wave (for time division duplex mould Formula is a carrier wave, includes uplink, downlink a pair of carrier wave for mode of frequency division duplexing, for convenience of description, referred to as one carries here Wave), it is only necessary to safeguard the uplink synchronous of a uplink, and in carrier wave polymerization, UE may be simultaneously operated in multiple components On carrier wave, and the TA of these component carriers is possible to different.This scene is referred to as more TA (MTA, Multiple TA).Make With the same TA and there are all cells of same downlink time reference to constitute a TA group (TA GROUP).

As previously mentioned, in single TA scenes, UE obtains the uplink synchronous between base station by random access procedure.At random Access procedure can by Physical Downlink Control Channel signaling (PDCCH order) or UE media access control layer (MAC, Medium Access Control) it initiates, optionally, PDCCH order or wireless heterogeneous networks (RRC, Radio Resource Control) signaling can be UE distribute special random access preamble (Random Access Preamble), then Random access procedure is the mode for being not based on competition；Otherwise UE needs to select random access guiding, then random access procedure is base In the mode of competition.UE select random access resource include selection random access guiding and Physical Random Access Channel (PRACH, Physical Random Access Channel) time-frequency domain resources etc..

Fig. 1 is based on competition random access procedure flow chart, as shown in Figure 1, based on competition (Contention based) Random access procedure include the following steps：

Step 101, UE is sent at random in uplink by random access channel (RACH, Random Access CHannel) Access lead (Random Access Preamble).

Step 102, the media access control layer (MAC, Medium Access Control) of base station (eNB) generates random Access response (RAR, Random Access Response) message, and in DSCH Downlink Shared Channel (DL-SCH, Downlink- Shared Channel) it is sent to UE；Random access guiding is included at least in the RAR message identifies (RAPID, Random Access Preamble IDentifier), time adjustment information (TA, Time Alignment), initial uplink mandate (UL Grant, Uplink Grant) and Temporary Cell-radio network temporary identifier (Temporary C-RNTI)；The message by Random access-wireless network on Physical Downlink Control Channel (PDCCH, Physical Downlink Control CHannel) Network temporary identifier (RA-RNTI, Random Access-Radio Network Temporary Identifier) is indicated； UE, which needs to receive in window at scheduled one, receives this accidental access response message.

Step 103, UE uplink share sent on transmission channel (UL-SCH, Uplink-Shared Channel) it is first Scheduled transmission (Scheduled Transmission) message；The content of the message is faced including at least cell-wireless network When mark (C-RNTI, Cell-Radio Network Temporary Identifier), media access control member (MAC Control Element) or include contention resolved mark (Contention Resolution Identity) public control Logic channel Service Data Unit (CCCH SDU) processed；Hybrid automatic repeat-request (HARQ, Hybrid are supported in the transmission of the message Automatic Retransmission re Quest)。

Step 104, base station sends contention resolution message (Contention Resolution) on DL-SCH；The message It is indicated by the C-RNTI or interim C-RNTI on PDCCH, may include contention resolved mark；The transmission of the message is supported HARQ。

Fig. 2 be based on non-competing random access procedure flow chart, as shown in Fig. 2, for non-competing random access procedure, There is no contention resolved process then, specifically includes following steps：

Step 201, UE sends random access guiding in uplink by random access channel.

Step 202, the media access control layer of base station generates accidental access response message, and is sent in DSCH Downlink Shared Channel To UE.

Random access procedure can only be carried out in main plot in traditional technology, cannot be carried out in secondary cell.

In the prior art, under MTA scenes, to obtain TA on SCell, UE must send RA on Scell Preamble, then UE corresponding RAR message is received on PCell.Traditional technology definition in the same subframe RA-RNTI and C-RNTI/ semi-persistent schedulings radio network temporary identifier (SPS-RNTI, Semi Persistent Scheduling-Radio Network Temporary Identifier) by use, UE need not decode those with C-RNTI/SPS-RNTI scrambling do Data indicated by the PDCCH of cyclic redundancy check (CRC, Cyclic Redundancy Check) are (in corresponding PDSCH Upper transmission).This is defined on traditional technology and is reasonable, and UE receives the scrambled RAR of RA-RNTI on PCell and just often anticipates Taste UE and the radio link quality of system is bad, therefore need not have other transmission and receive process.Therefore, different carrier wave It can not simultaneous transmission/reception RA-RNTI scramblings and the scrambled information of C-RNTI/SPS-RNTI.In multi-carrier systems, due to drawing Entered MTA scenes, if UE received on PCELL the scrambled RAR of RA-RNTI it is corresponding be SCell random access procedure, this When just and UE and the radio link quality of system it is no longer related, be possible at this time simultaneous transmission/reception RA-RNTI scramble with The scrambled information of C-RNTI/SPS-RNTI.

In view of the above-mentioned problems, not yet related art scheme can be for reference at present.

Example one

UE receives the RAR message of corresponding random access procedure in PCell, and judging whether can be simultaneously in one or more The PDSCH of bearing downlink data (DL-SCH) is received and decoded in SCell.

Judge whether to receive and decode in one or more SCell simultaneously the PDSCH of bearing downlink data (DL-SCH), Specially：

Judge whether RAR message corresponds to the random access procedure of SCell, if so, UE is according to the DL SCell's of activation Set is searched in the set on SCell to the PDSCH of the UE and is decoded；If it is not, UE is without on SCell The decoding of PDSCH.

When receiving RAR message, judge whether the uplink PCell of UE is synchronous (i.e. PCell uplink synchronous timer TAT ) effectively whether, if synchronous, whether UE carries to this during search is gathered on SCell according to the set of the DL SCell of activation UEPDSCH is simultaneously decoded；If it is not, decodings of the UE without the PDSCH on SCell.

Wherein, UE detects RA- according to the RA-RNTI sent on SCell corresponding to the Preamble moment on PCell The scrambled PDCCH of RNTI simultaneously decode the PDCCH corresponding PDSCH acquisitions RAR message；Bearing downlink is received on SCell The scheduling of PDSCH is obtained when the PDSCH of data using the scrambled PDCCH of C-RNTI/SPS-RNTI detection C-RNTI/SPS-RNTI Authorization message (DL-Grant).

One or more of SCell can be with PCell in the same TA groups, can not also be in the same TA groups.

After UE decodes the PDSCH of SCell, if PCell uplink synchronous timer (TAT) is still valid, UE MAC HARQ are real The feedback (ACK/NACK) that body normally sends the downlink data in corresponding SCell arrives physical layer, described in the physical layer feedback of UE ACK/NACK is to base station.

Example two

Base station sends UE in the corresponding RAR message of SCell random access in the PCell of UE, and judging whether can be simultaneously one Downlink data is sent in a or multiple SCell.The wherein RAR message of PCell is scrambled using RA-RNTI, the downlink data of SCell It is scrambled using C-RNTI/SPS-RNTI.

Judge whether to send downlink data in one or more SCell simultaneously, specifically include：

Before base station sends RAR message and downlink data in PCell and one or more SCell simultaneously, institute is judged The random access procedure whether RAR corresponds to SCell is stated, if so, just sending the RAR of corresponding SCell random access procedures simultaneously Downlink data in message and one or more SCell.

After base station sends RAR message and downlink data in PCell and one or more SCell simultaneously, institute is judged The random access procedure whether RAR corresponds to SCell is stated, if so, the just detection feedback (ACK/ in corresponding sub-frame of uplink NACK) corresponding PUCCH receives the feedback.

Whether the uplink PCell of base station detection UE before receiving the feedback (ACK/NACK) is synchronous (i.e. PCell Whether uplink synchronous timer TAT is effective), if synchronous, just detection feedback (ACK/NACK) is right in corresponding sub-frame of uplink The PUCCH answered receives the feedback.

Example three

UE receives the RAR message of corresponding random access procedure in PCell, judges whether to receive simultaneously in PCell simultaneously Decode the PDSCH of bearing downlink data (DL-SCH).

Judge whether to receive and decode simultaneously the PDSCH of bearing downlink data (DL-SCH) in PCell, including：

Judge whether the RAR message corresponds to the random access procedure of SCell, if so, searching on the PCell to this The PDSCH of UE is simultaneously decoded；If it is not, decodings of the UE without the PDSCH on PCell.

When receiving RAR message, judge whether the uplink PCell of UE is synchronous (i.e. PCell uplink synchronous timer TAT Whether effectively), if it is synchronous, whether there is carrying to the UEPDSCH on UE search PCell and is decoded；If it is not, UE is not Carry out the decoding of the PDSCH on PCell.

UE detects RA-RNTI according to the RA-RNTI sent on SCell corresponding to the Preamble moment on PCell and adds The PDCCH that disturbs simultaneously decodes the corresponding PDSCH of the PDCCH and obtains the RAR message；Bearing downlink data are received on PCell The scheduling authorization that PDSCH is obtained using the scrambled PDCCH of C-RNTI/SPS-RNTI detection C-RNTI/SPS-RNTI when PDSCH is believed It ceases (DL-Grant).

After UE decodes the PDSCH of PCell, if PCell uplink synchronous timer (TAT) is still valid, UE MAC HARQ are real The feedback (ACK/NACK) that body normally sends the downlink data in corresponding PCell arrives physical layer, described in the physical layer feedback of UE ACK/NACK is to base station.

Example four

Base station sends UE in the corresponding RAR message of SCell random access in the PCell of UE, judges whether simultaneously to exist Downlink data is sent in PCell.The RAR message of wherein PCell is scrambled using RA-RNTI, and the downlink data of PCell uses C-RNTI/SPS-RNTI is scrambled.

Judge whether to send downlink data in PCell simultaneously, including：

Before base station sends RAR message and downlink data in PCell simultaneously, to judge whether the RAR corresponds to SCell Random access procedure.If so, just simultaneously send corresponding SCell random access procedures RAR message and PCell under Row data.

After base station sends RAR message and downlink data in PCell simultaneously, to judge whether the RAR corresponds to SCell Random access procedure, if so, just detection feedback (ACK/NACK) corresponding PUCCH receives institute in corresponding sub-frame of uplink State feedback.

Example five

After UE decodes the PDSCH of SCell, if PCell uplink synchronous timer (TAT) is still valid, UE MAC HARQ are real The feedback (ACK/NACK) that body normally sends the downlink data in corresponding SCell arrives physical layer, described in the physical layer feedback of UE The base stations ACK/NACK to Pico.

Example six

The base stations Pico send UE in the corresponding RAR message of SCell random access in the PCell of UE, and judging whether can be simultaneously Downlink data is sent in one or more SCell.The wherein RAR message of PCell is scrambled using RA-RNTI, the downlink of SCell Data are scrambled using C-RNTI/SPS-RNTI.

The corresponding PUCCH of feedback (ACK/NACK) is detected in corresponding sub-frame of uplink and receives the feedback in the base stations Pico.

Before the base stations Pico send RAR message and downlink data in PCell and one or more SCell simultaneously, to sentence Whether the RAR that breaks corresponds to the random access procedure of SCell, if so, just sending corresponding SCell random access procedures simultaneously Downlink data in RAR message and one or more SCell.

After the base stations Pico send RAR message and downlink data in PCell and one or more SCell simultaneously, to sentence Whether the RAR that breaks corresponds to the random access procedure of SCell, if so, the just detection feedback (ACK/ in corresponding sub-frame of uplink NACK) corresponding PUCCH receives the feedback.
