The embodiment of the present application provides a kind of ascending HARQ transmission method, is applied to communication system shown in FIG. 1 to FIG. 4, such as Shown in Fig. 7 A, it the described method comprises the following steps:
701, terminal sends the second information to the access network equipment, and the second information is used to indicate terminal and supports the first uplink Carrier wave and the second up-link carrier share the first HARQ process.
It should be noted that the first up-link carrier, the second up-link carrier are two uplinks configured between access network equipment Carrier wave, the first HARQ process are any one in the HARQ process for uplink.First up-link carrier, the second uplink carry Wave shares a HARQ process, i.e. identical HARQ process can be used in terminal on two different carrier waves, for example, first Uplink can be carried out by the first HARQ process on up-link carrier, the first HARQ can also be passed through on the second up-link carrier Process carries out uplink.
In the embodiment of the present application, when the first up-link carrier and the second up-link carrier share the first HARQ process, the first uplink Carrier wave and the second up-link carrier can share the HARQ caching of the first HARQ process.When terminal is on the first up-link carrier, pass through When first HARQ process sends data, data are obtained in the HARQ caching of the first HARQ process.When terminal is carried in the second uplink On wave, when sending data by the first HARQ process, data are obtained in the HARQ caching of the first HARQ process.
In the specific implementation, terminal can send the first up-link carrier and the second up-link carrier by following two mode.
The first, the first up-link carrier and the second up-link carrier scene of supporting TDM to send, i.e. terminal cannot be concurrent simultaneously First up-link carrier and the second up-link carrier, send the first up-link carrier and the second up-link carrier in a manner of TDM.For example, Under SUL scene, the first up-link carrier is NUL carrier wave, and the second up-link carrier is SUL carrier wave, and NUL carrier wave and SUL carrier wave are with TDM's Mode is sent；Either the first up-link carrier and the second up-link carrier are the up-link carrier under CA scene or under DC scene.
It needs, the first up-link carrier and the second up-link carrier are sent in a manner of TDM, it can be understood as same The first up-link carrier of time and the second up-link carrier will not be sent simultaneously, or can be with the uplink time-domain resource of the first up-link carrier It is not overlapped with the uplink time-domain resource of the second up-link carrier.In addition, up-link carrier is sent in the embodiment of the present application, or send Up-link carrier can be understood as sending upstream data by up-link carrier.
Optionally, in this implementation, the first up-link carrier is being carried out in a manner of TDM with the second up-link carrier Multiple-input and multiple-output (multi-input multi-output, MIMO) ability and the first up-link carrier when row transmission is in single load MIMO ability under wave transmission mode is identical；Second up-link carrier is when with first up-link carrier uplink in a manner of TDM MIMO ability it is identical as MIMO ability of second up-link carrier under the mode of single carrier transmission.Wherein, MIMO ability can be with The quantity for the radio-frequency channel that the MIMO layer number or the carrier wave for being interpreted as carrier wave support are supported.Exemplary, terminal is with the side of TDM When formula sends the first up-link carrier, the second up-link carrier, the MIMO layer number that the first up-link carrier is supported, on terminal single-shot first The MIMO layer number that the first up-link carrier is supported when row carrier wave is identical；The MIMO layer number that second up-link carrier is supported, with terminal single-shot The MIMO layer number that the second up-link carrier is supported when the second up-link carrier is identical.
For example, as shown in figure 7b, the first up-link carrier and the second up-link carrier share radio-frequency channel 1 and radio-frequency channel 2, when the When one up-link carrier is with single carrier transmission mode (or can be understood as single shot mode) work, switch 1 works in state 1, opens 2 work are closed in state 1, provide the first up-link carrier 2T by radio-frequency channel 1 and radio-frequency channel 2；When the second up-link carrier is with list When carrier-wave transmission mode (or can be understood as single shot mode) works, in state 2, switch 2 works in state 2 work of switch 1, Secondary cell up-link carrier 2T is provided by radio-frequency channel 1 and radio-frequency channel 2.
If present first up-link carrier and the second up-link carrier are sent in a manner of TDM, when the first up-link carrier works Radio-frequency channel 1 and radio-frequency channel 2 can be used；First up-link carrier can also use radio-frequency channel 1 and radio-frequency channel when working 2。
Optionally, in the first implementation, since the first up-link carrier and the second up-link carrier timesharing are sent, terminal When passing through a HARQ process transmission data on some up-link carrier, which can be used the up-link carrier in single load MIMO ability under wave transmission mode.
For example, the first up-link carrier and the second up-link carrier timesharing are sent, and terminal is in some uplink in the example of Fig. 7 B When passing through a HARQ process transmission data on carrier wave, 2 radio-frequency channels, i.e. radio-frequency channel 1 and radio-frequency channel 2 can be occupied.
Second, the scene that the first up-link carrier and the second up-link carrier support multicarrier concurrent.For example, the first uplink carries Wave and the second up-link carrier support CA.Alternatively, the first up-link carrier is main cell group up-link carrier, the second uplink under DC scene Cell group up-link carrier supplemented by carrier wave.
First up-link carrier and the second up-link carrier are sent in concurrent mode, it can be understood as in the same time, first Up-link carrier and the second up-link carrier can send simultaneously perhaps have and meanwhile the ability that sends or the first up-link carrier it is upper There may be overlappings for row time-domain resource and the uplink time-domain resource of the second up-link carrier.
Optionally, in the second implementation, since the first up-link carrier and the second up-link carrier are sent simultaneously, first The MIMO ability under concurrent mode can be used in up-link carrier and the second up-link carrier.
For example, first the first up-link carrier of up-link carrier and the second up-link carrier are sent simultaneously in the schematic diagram of Fig. 7 B, First up-link carrier can use radio-frequency channel 1, and the second up-link carrier can use radio-frequency channel 2.Terminal is carried in some uplink When passing through a HARQ process transmission data on wave, 1 radio-frequency channel can be occupied.
Optionally, in the second implementation, the data in a HARQ process can be sent with timesharing, but multiple HARQ process can be concurrent, for example, the same time, a data block is sent by HARQ process 1 on the first up-link carrier, on second Another data block is sent by HARQ process 2 on row carrier wave.
In the specific implementation, the second information can be the ability information that terminal reports, the ability information is used to indicate terminal Multicarrier whether is supported to share HARQ process, terminal can notify access network equipment by the second information, and terminal supports multicarrier Shared HARQ process, i.e. terminal can pass through the same HARQ process transmission data on different up-link carriers.
It should be noted that 701 be optional step.For example, access network equipment and terminal can default terminal support it is more Carrier wave shares HARQ process, reports without terminal by 701.
702, access network equipment sends the first information to terminal, and the first information is for enabling the first up-link carrier and second Row carrier wave shares the first HARQ process.
In the specific implementation, access network equipment can (i.e. the application be implemented according to the ability information that terminal is reported in step 701 Second information described in example), determine that terminal has the ability that multicarrier shares HARQ process.Access network equipment can pass through first Information notifies terminal to open the ability that multicarrier shares HARQ process.For example, access network equipment can send the first letter to terminal Breath, terminal open the ability that multicarrier shares HARQ process after receiving the first information, support the first up-link carrier and the second uplink Carrier wave shares the first HARQ process.
In a kind of possible implementation, access network equipment can pass through wireless heterogeneous networks (radio resource Control, RRC) signaling, accessing wirelessly control control element (media access control control element, MAC CE) or Downlink Control Information (downlink control information, DCI) to terminal send the first information. The first information can be RRC signaling in hair, increased 1bit information in MAC CE or DCI.This 1bit information is used to indicate terminal Whether ability that multicarrier share HARQ process is opened.Exemplary, the first information is " 0 ", is used to indicate terminal and is not turned on overloading Wave shares the ability of HARQ process, and terminal does not support then the first up-link carrier and the second up-link carrier to share the first HARQ process； The first information is " 1 ", is used to indicate terminal and opens the ability that multicarrier shares HARQ process, terminal then supports the first up-link carrier The first HARQ process is shared with the second up-link carrier.
S702 is optional.For example, access network equipment and terminal, which can default enabled multicarrier, shares HARQ process, without Access network equipment is needed to issue the enabled information by 702.
703, terminal sends the first transmission block to access network equipment by the first HARQ process on the first up-link carrier； On the second up-link carrier, the second transmission block is sent to access network equipment by the first HARQ process.
Due to using the first HARQ process, the second transmission block (transport block, TB) and the first transmission block are with TDM Mode transmitted.It is exemplary, it is not weighed for the time-domain resource of the first transmission block and the time-domain resource for the second transmission block It is folded, alternatively, the time-domain resource for the first transmission block is different with the time-domain resource for the second transmission block.
In a kind of possible implementation, first transmission block is new biography data block；Second transmission block is described The re-transmitting data block of first transmission block.
In alternatively possible implementation, first transmission block is new biography data block；Second transmission block is new Pass data block.
Optionally, in method shown in Fig. 7 A, access network equipment can pass through UL Grant (uplink authorization) dispatching uplink Data, for example, above-mentioned first transmission block or the second transmission block.UL Grant includes the ID and NDI of HARQ process.
Specifically, which is passed through by the upstream data of the HARQ process ID instruction terminal current scheduling in UL Grant HARQ process is sent.It is exemplary, it is assumed that the ID of above-mentioned first HARQ process is " 1 ", the HARQ process ID in UL Grant For " 1 ", the transmission block being used to indicate in the HARQ caching for sending the first HARQ process by the first HARQ process.
In addition, by NDI indicate this UL Grant of access network equipment scheduling be new biography data or retransmit data.Tool Body, the more last overturning of NDI, it is determined that this UL Grant scheduling is new biography data, and terminal is currently having conveyer On the up-link carrier of meeting, the HARQ process indicated by UL Grant sends the new biography data in the HARQ caching of the HARQ process (the first transmission block as described in the embodiment of the present application).
It is and primary if what the UL Grant of access network equipment dispatched is to retransmit data in a kind of possible implementation Re-transmission can not transfer all re-transmission data, and terminal can retransmit several times.First biography data solution of the access network equipment to terminal After adjusting failure, terminal retransmits data several times, and the data after access network equipment can repeatedly retransmit terminal combine, then and just passes Data merge, and obtain and merge decoded gain.
Exemplary, the first transmission block is just to pass data, and the second transmission block is the corresponding re-transmission data of the first transmission block.Second Transmission block includes N number of sub- transmission block, and N is the integer more than or equal to 1, and N number of sub- transmission block is Ri, i is to take all over 0 to N-1's Integer.
Access network equipment dispatches a sub- transmission block R by a UL Granti, terminal is from access network equipment UL Grant, UL Grant include a sub- transmission block RiControl information, which includes the mark of the first HARQ process ID, NDI and the sub- transmission block RiResource allocation information, the NDI do not overturn.
Terminal judges that NDI is not flipped than before, and determine this UL Grant scheduling is to retransmit data, then according to son Transmission block RiControl information, the first HARQ process HARQ caching in obtain sub- transmission block Ri, the second up-link carrier (i.e. Currently have the up-link carrier of transmission opportunity) on, the sub- transmission block is sent to the access network equipment using the first HARQ process Ri。
It should be noted that currently there is the up-link carrier of transmission opportunity in the embodiment of the present application, i.e., currently there is transfer resource, It can be used for the up-link carrier of uplink.
Below with the first up-link carrier be 3.5G up-link carrier, the second up-link carrier be 2.1G up-link carrier for, in conjunction with Fig. 8 explains method described in the embodiment of the present application.
With reference to Fig. 8,3.5G up-link carrier and 2.1G up-link carrier can share 16 HARQ processes, wherein each HARQ Process can be used for carrying out the uplink of TDM mode in 3.5G up-link carrier and 2.1G up-link carrier.It is exemplary, access network equipment Scheduled TB1 in the 1st time slot (Slot0) of 2.6G up-link carrier, the UL grant for uplink scheduling indicate HARQ into ID, NDI of journey, 1, RB quantity M modulating-coding strategy (modulation and coding scheme, MCS)1And transmission block Size.Where it is assumed that the ID instruction HARQ process 0 (i.e. the HARQ process that ID is 0) of HARQ process, transport block size is used to indicate The size of TB1, RB quantity M1It is used to indicate the RB quantity that transmission TB1 is used, the strategy that MCS1 is used to indicate modulation, encodes TB1.
After access network equipment receives TB1, data demodulation failure, access network equipment calculating earliest can be in 2.1GHz uplink 3rd time slot (Slot2) schedule re-transmission data of carrier wave.With reference to Fig. 8 it is found that 2.1GHz up-link carrier does not have resource in Slot2 Carry out uplink.Terminal cannot retransmit data in the Slot2 of 2.1GHz up-link carrier.But 3.5GHz up-link carrier Slot4 has the resource of uplink, and it is corresponding heavy that access network equipment then can send TB1 in the Slot4 of 3.5GHz up-link carrier Pass data.
Specifically, access network equipment can send UL grant in the Slot3 of 3.5GHz up-link carrier, dispatch on 3.5GHz The upstream data of the Slot4 of row carrier wave, the UL grant sent on the Slot3 of 3.5GHz up-link carrier includes HARQ process ID, MCS2, distribution RB quantity M2, transport block size and NDI.Wherein, transport block size is identical as the size of TB1；NDI is not turned over Turn (for example, NDI is NDI in 0, UL grant or 0) originally；The ID of HARQ process is 0.
Terminal judges that NDI is not overturn, determines that the Slot4 of 3.5GHz up-link carrier retransmits data by HARQ process 0.Terminal TB2 (i.e. the re-transmission data of TB1) can be obtained in the HARQ of HARQ process 0 caching, by HARQ process 0 in 3.5GHz uplink The Slot4 of carrier wave sends TB2.Specifically, using MCS2 modulating-coding TB2, and in M2TB2 is sent on a RB.
After access network equipment receives the TB2 sent on the Slot4 of 3.5GHz up-link carrier, TB1 and TB2 are closed And it obtains and merges decoded gain.
It should be noted that can not once have been sent if the RB resource on the Slot4 of 3.5GHz up-link carrier is very little TB2 can then send TB2 several times, and terminal sends a sub- transmission block every time, and each transmission requires access network equipment and leads to UL grant is crossed individually to dispatch.After access net receives all sub- transmission blocks, closed by all sub- transmission merged blocks, then with TB1 And it decodes.
In addition, SS later sends sub- transmission block on the up-link carrier for have transmission opportunity.For example, can be on 3.5GHz The transmission opportunity of row carrier wave sends sub- transmission block, can also send sub- transmission block in the transmission opportunity of 2.6GHz up-link carrier.
In a kind of possible implementation, the second information in 701 can also include carrier combination information.The carrier wave set Close the carrier combination shared for HARQ process that information is used to indicate terminal support.For example, carrier combination information is 2.1GHz And 3.5GHz, it is used to indicate terminal and 2.1GHz up-link carrier and 3.5GHz up-link carrier is supported to share the same HARQ process.
Table 1 shows a kind of example of different frequency range division.As shown in table 1, in 5G NR system, frequency range has been carried out stroke Point, different frequency ranges supports different dual-modes.For FDD duplex mode, up-link carrier and descending carrier are respectively in difference Frequency range on transmit, and identical frequency spectrum resource is shared for TDD duplex mode, up-link carrier and descending carrier, by using Different time is transmitted.5G NR system also defines SUL carrier wave frequency range, which transmits for uplink, supports uplink The frequency range decoupling that link and downlink use.

Specifically, carrier combination information may include the mark of two frequency ranges shown in table 1, be used to indicate terminal support with Two up-link carriers that TDM mode is transmitted, two up-link carriers of the two frequency ranges mark instruction can be shared same HARQ process.Exemplary, carrier combination information indicates frequency range mark instruction n3, n7, i.e. 1710MHz -1785MHz up-link carrier With 2500MHz -2570MHz up-link carrier support transmitted in a tdm fashion, 1710MHz -1785MHz up-link carrier and 2500MHz -2570MHz up-link carrier can share the same HARQ process.
Fig. 7 A is described by taking two up-link carriers as an example, it should be noted that above content is equally applicable to multiple Carrier wave (such as 3,4 or more) shares same HARQ process, in the same HARQ process, the transmission block of multiple carrier waves It is transmitted in a manner of TDM.
Under CA scene, terminal can report the frequency range for supporting CA to combine according to table 1 to access network equipment.Terminal can connect The downlink signal from multiple descending carriers is received, or, sending uplink signal on multiple up-link carriers simultaneously.Uplink CA scene In, the MIMO ability of each CC (carrier wave) of polymerization, which is compared with maximum transmission power under single carrier transmission mode, to be declined.With For n77 3.5GHz up-link carrier and the polymerization of n3 1.8GHz up-link carrier, terminal is needed to have while being carried in 3.5GHz uplink Wave and 1.8GHz up-link carrier send the ability of upstream data, and power consumption is big, and stand-by time is short.Secondly, 3.5GHz up-link carrier, 1.8GHz up-link carrier can only use 1 antenna to be sent, and maximum transmission power is also reduced to by the 26dBm of original single carrier 23dBm, the performance on each carrier wave can decline relative to single carrier transmission mode, and the overall performance of uplink communication is promoted unknown It is aobvious.In addition, up-link carrier is concurrently more demanding for terminal complexity, many terminals do not support uplink CA.
The embodiment of the present application also provides a kind of communication means, does not require the ability for having uplink CA, reduces to terminal complexity The performance of the requirement of degree, single carrier can't decline, and can effectively utilize ascending wireless resource, promote the property of uplink communication Energy.As shown in figure 9, the described method comprises the following steps:
901, for terminal to access network equipment reporting ability information, ability information is used to indicate the up-link carrier frequency of terminal support Section.
In a kind of possible implementation, ability information may include the mark for all up-link carrier frequency ranges that terminal is supported Know, for example, n3, n5 and n7 shown in terminal support matrix 1.Ability information may include n3, n5 and n7, and instruction terminal is supported 1710MHz -1785MHz up-link carrier, 824MHz -849MHz up-link carrier and 2500MHz -2570MHz up-link carrier.
In alternatively possible implementation, the specific field instruction terminal in ability information supports specified up-link carrier Frequency range.For example, terminal accesses network in 3.5GHz frequency range, FreqBandInformationNR word is reported in ability information Section, by FreqBandInformationNR field indicate access network equipment, terminal support 3.5GHz frequency range carrier wave and The carrier wave of 2.1GHz frequency range.
Optionally, it should be noted that also can indicate that other ability informations of terminal in ability information, such as: terminal is No support downlink CA, whether support transmission duplex, if support that uplink CA and terminal switch between two carrier waves when Prolong.Exemplary, 1 instruction terminal of BandCombination field in ability information supports 3.5G descending carrier and 2.1G downlink The downlink CA of carrier wave；The simultaneousRxTxInterBandCA in CA-ParametersNR field in ability information refers to Show that terminal supports the carrier transmitting-receiving duplex in 3.5G frequency range and 2.1G frequency range, i.e. terminal line number in the case where synchronization can receive According to, and upstream data can be sent.BandCombination field 2 in ability information is used to indicate terminal and supports under 3.5G The uplink CA of row carrier wave and 2.1G descending carrier.
It should be noted that BandCombination field 1 and BandCombination field 2 are in ability information Position is different, is properly termed as " BandCombination " field, " BandCombination " the field difference of different location It is used to indicate the ability of terminal uplink CA, the ability of user equipment downlink CA.
Optionally, since terminal does not have the ability of uplink CA, the ability information in 901 can not be supported with instruction terminal Row CA.
In the first possible implementation, the ability information instruction terminal that terminal reports supports multicarrier TDM transmission. Optionally, which also can indicate that terminal supports the frequency range combination of multicarrier TDM transmission, such as n3+n5+n5.
In the second possible implementation, the ability information that terminal reports can not instruction terminal support multicarrier TDM transmission.
902, the ability information that access network equipment is reported according to terminal selects the first up-link carrier and the second up-link carrier； First up-link carrier and the second up-link carrier are transmitted in a tdm fashion.
In the specific implementation, access network equipment determines that multiple uplinks that terminal is supported carry according to the ability information that terminal reports Wave, and determine that terminal is used for two uplink up-link carriers of TDM transmission in above-mentioned multiple carrier waves, i.e., described in the embodiment of the present application The first up-link carrier and the second up-link carrier.
In the first possible implementation, the ability information instruction terminal that terminal reports supports multicarrier TDM transmission Or terminal supports the frequency range combination of multicarrier TDM transmission, access network equipment can determine two according to the ability information and be used for The up-link carrier of TDM transmission, i.e. the first up-link carrier and the second up-link carrier described in the embodiment of the present application.
In the second possible implementation, the ability information that terminal reports can not instruction terminal support multicarrier TDM transmission (or terminal supports the frequency range of multicarrier TDM transmission to combine).The upper line frequency that access network equipment can support terminal One or more in section is configured to TDM.
It should be noted that identical duplex mode can be used in the first up-link carrier and the second up-link carrier, on first Row carrier wave and the second up-link carrier are all made of TDD dual-mode.First up-link carrier and the second up-link carrier also can be used not Same duplex mode, such as the first up-link carrier use FDD dual-mode, and the second up-link carrier uses TDD dual-mode.First carries Different subcarrier spacing (Numerology) can be used in wave and the second carrier wave or identical subcarrier will.
903, access network equipment sends the information of the first up-link carrier and the information of the second up-link carrier to terminal.
In the specific implementation, the first up-link carrier can be the carrier wave that terminal is currently accessed, the second up-link carrier is access net Equipment is determined that terminal is supported and can be transmitted in a tdm fashion with the first up-link carrier according to the ability information that terminal reports Up-link carrier.
The information of first up-link carrier can be on the channel configuration information and first in frequency range locating for the first up-link carrier Signal configuration information in frequency range locating for row carrier wave.Wherein, the channel configuration information in frequency range locating for the first up-link carrier can be with It is PUSCH information, PUCCH information, the signal configuration information in frequency range locating for the first up-link carrier can be SCS information, SRS letter Breath.
The information of second up-link carrier can be on the channel configuration information and second in frequency range locating for the second up-link carrier Signal configuration information in frequency range locating for row carrier wave.Wherein, the channel configuration information in frequency range locating for the second up-link carrier can be with It is PUSCH information, PUCCH information, the signal configuration information in frequency range locating for the second up-link carrier can be SCS information, SRS letter Breath.
In a kind of possible implementation, terminal accesses the cell of the first up-link carrier before step 801, accesses herein Net equipment only needs to issue the information of the second up-link carrier to terminal.Exemplary, terminal has accessed the small of 3.5GHz up-link carrier Area, the ability information reported according to terminal determine that terminal supports 3.5GHz up-link carrier and 2.1GHz up-link carrier time sharing transmissions, Then to the information of terminal configuration 2.1GHz up-link carrier in RRC reallocation message, such as SCS information, PUSCH letter in 2.1G frequency range Breath, SRS information and PUCCH information.
By taking terminal supports 3.5GHz up-link carrier and 2.1GHz up-link carrier as an example, terminal does not support uplink CA.Access net It is 3.5GHz up-link carrier, the second up-link carrier that the ability that equipment is reported according to terminal, which is the first up-link carrier of terminal configuration, For 2.1GHz up-link carrier, dispatching uplink is distinguished on 3.5GHz up-link carrier and 2.1GHz up-link carrier by way of the time-division Data avoid uplink concurrent, reduce terminal implementation complexity.Since 3.5GHz frequency range is TDD system, in TDD descending time slot In resource, uplink does not send data.After configuring 2.1GHz up-link carrier to terminal, on the TDD descending time slot of 3.5GHz, terminal Upstream data can be sent using 2.1G up-link carrier, in the TDD ascending time slot of 3.5GHz, not in 2.1GHz frequency range in scheduling Row data guarantee that terminal only sends data on a up-link carrier always.In addition, the frequency range of carrier wave is different, the covering of carrier wave Range is different.In general, the carrier wave that frequency range is lower, coverage area are bigger.Since the coverage area of 2.1GHz up-link carrier is big Upstream data is only dispatched on 2.1GHz up-link carrier, is promoted for being located at the user of cell edge in 3.5GHz up-link carrier Uplink coverage area.
How the content introduction of above figure 9 configures the first up-link carrier and the second up-link carrier, only a kind of example, First up-link carrier and the second up-link carrier can also configure by other means, the embodiment of the present application to this with no restriction.? After configuring the first up-link carrier and the second up-link carrier, can activate or deactivate, below by taking the second up-link carrier as an example into Row is introduced.Perhaps deactivated content can merge execution with Fig. 9 or be performed separately with Fig. 9 for activation below.
In a kind of optional implementation, after access network equipment has configured the second up-link carrier, can by MAC CE or Person DCI signaling come notify terminal activate or deactivate the second up-link carrier.
Specifically, access network equipment judges whether the second up-link carrier meets activation condition, in the feelings for meeting activation condition Under condition, base station can be activated by MAC CE or DCI message informing the second up-link carrier of terminal.Similarly, access network equipment judges Two up-link carriers are unsatisfactory for activation condition, can deactivate the second up-link carrier by MAC CE or DCI message informing terminal.
As a kind of implementation, activation condition can be the downlink synchronous signal block measured on the second up-link carrier (synchronization signal block, SSB) or channel state information reference signals (channel State Information-reference signals, CSI-RS) Reference Signal Received Power (reference signal Receiving power, RSRP) meet certain thresholding.
In alternatively possible implementation, after access network equipment has configured the second up-link carrier, the second uplink of default is carried Wave is active.
It is described above and how to activate or deactivate up-link carrier.Following describe in terminal moving process, source is connect How log equipment and target access network equipment transmit the configuration information of up-link carrier.Below content can with above configuration on One or more in the scheme of row carrier wave and (going) activation up-link carrier is performed separately or merges execution.
In a kind of optional implementation, in terminal moving process, terminal will do it cell switching.Access network equipment can With during terminal switching cell, source access network equipment passes through the interface between access network equipment for the energy of the terminal in s901 Force information is sent to target access network equipment, and then target access network is accessed according to the ability information collocating uplink carrier wave to source Net equipment sends uplink configuration information, and source access network equipment sends the uplink configuration information to terminal, such as target access network is set It is standby to pass through switching (handover, HO) signaling for the information configuration of the second up-link carrier to terminal.Alternatively, access network equipment is at end After cell switching is completed at end, by RRC reallocation message by the information configuration of the second up-link carrier to terminal.
Wherein, the information of the second up-link carrier may include the wireless resource configuration of the second up-link carrier.
