Description

Signaling reconfiguration processing method and device
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a method and a device for processing signaling reconfiguration.
Background
Since the R8/R9 version of LTE only adopts a single carrier technology, and downlink and uplink rates are greatly limited, but the requirement for the moving speed is higher and higher, the multi-carrier aggregation technology of LTE (long Term evolution) is developed in the R10 version. Carrier Aggregation (CA) is to aggregate 2 or more Carrier units (Component carriers, CCs) together to obtain a larger system bandwidth (up to a system bandwidth of 100 MHz).
An ACK (Acknowledgement) feedback mode applicable to a single carrier is only bundling (binding mode) and multiplex (multiplexing mode); the ACK feedback mode for at least 2 carriers adds format 1b with channel selection and format 3. However, by adopting the LTE carrier aggregation technology of the R10 version, when the base station reconfigures the carrier signaling for the UE, due to a dead zone of handover of the carrier reconfiguration parameter between the base station and the UE, the technical problems of carrier signaling reconfiguration failure between the base station and the UE and service rate reduction are caused.
For example, in the process of configuring multiple carriers and deleting carriers for the UE, a blind area of switching between ACK feedback modes may occur in a processing flow of an existing HARQ (Hybrid automatic repeat request).
As shown in the schematic diagram of the blind area of ACK feedback mode switching shown in fig. 1, according to the existing HARQ processing flow, a base station sends downlink data to a UE at subframe number 0, and at subframe number 4, the UE transmits a downlink decoding result in an old ACK feedback mode suitable for a single carrier scenario; in subframe number 5, configuring a multi-carrier reconfiguration instruction for the UE by a base station RRC (Radio Resource Control) layer, and in the next subframe number 1, sending a reconfiguration completion signaling to the base station by the UE, and transmitting a downlink decoding result to the base station by adopting a new ACK feedback mode for received downlink data; in the subsequent subframe number, the RRC Layer of the base station informs the MAC (Medium Access Control) Layer and the PHY (Physical Layer) Layer that the reconfiguration signaling is completed, and the MAC Layer and the PHY Layer use a new ACK feedback mode to decode the downlink decoding result transmitted by the UE. The blind area of the ACK feedback mode switching refers to a time period from the RRC of the base station configuring the multi-carrier reconfiguration command to the RRC layer of the base station informing the completion of the reconfiguration signaling of the MAC layer and the PHY layer.
Fig. 2 shows a schematic diagram of an ACK feedback mode switching blind area, where the blind area is caused by signaling interaction between a base station and a UE needing to span different layers, and during the generation of the ACK feedback mode switching blind area between step 1 and step 7, a MAC layer and a PHY layer of the base station need to switch a channel ACK feedback mode after receiving a reconfiguration complete signaling of an RRC layer, but after the UE receives a multi-carrier reconfiguration signaling, the RRC layer of the UE analyzes reconfiguration information of the multi-carrier reconfiguration signaling and then informs the MAC layer and the PHY layer of the UE to transmit a downlink decoding result to the base station side by using a new ACK feedback mode. Therefore, before the MAC layer and the PHY layer of the base station receive the reconfiguration complete signaling of the RRC layer, the UE has already transmitted the downlink decoding result to the base station side using the new ACK feedback mode, and for the MAC layer and the PHY layer of the base station, it is difficult to accurately determine at which time point the new ACK feedback mode used by the UE is valid.
In summary, in the prior art, when the base station reconfigures signaling for the UE, a handover blind area of reconfiguration parameters exists between the base station and the UE, which results in signaling reconfiguration failure between the base station and the UE and service rate reduction.
Disclosure of Invention
The embodiment of the invention provides a method and a device for processing signaling reconfiguration, which are used for solving the technical problems that when a base station reconfigures signaling for UE (user equipment), signaling reconfiguration failure and service rate reduction between the base station and the UE are caused due to a switching blind area of reconfiguration parameters between the base station and the UE in the prior art.
The embodiment of the invention provides a signaling reconfiguration processing method, which comprises the following steps:
when determining that the UE meets the signaling reconfiguration condition, issuing a reconfiguration signaling to the UE;
determining the transmission times of transmitting downlink data to the UE in a multi-redundancy version mode;
according to the determined transmission times, transmitting downlink data to the UE in a multi-redundancy version mode so that the UE can correctly receive the transmitted downlink data;
and receiving the reconfiguration finishing signaling fed back by the UE, and stopping transmitting downlink data to the UE in a multi-redundancy version mode according to the reconfiguration finishing signaling.
An embodiment of the present invention provides a signaling reconfiguration processing apparatus, including:
the processing unit is used for indicating the transceiver unit to issue the reconfiguration signaling to the UE when the UE is determined to meet the signaling reconfiguration condition; determining the transmission times of transmitting downlink data to the UE in a multi-redundancy version mode; according to the determined transmission times, the transceiver unit is instructed to transmit downlink data to the UE in a multi-redundancy version mode, so that the UE can correctly receive the transmitted downlink data;
the receiving and sending unit is used for issuing a reconfiguration signaling to the UE according to the indication of the processing unit and transmitting downlink data to the UE in a multi-redundancy version mode;
a transceiver unit, configured to receive a reconfiguration complete signaling fed back by the UE;
the processing unit is further configured to instruct the transceiver unit to stop transmitting downlink data to the UE in a multiple redundancy version mode according to the reconfiguration complete signaling received by the transceiver unit.
In the above embodiment, when the base station determines that the UE satisfies the signaling reconfiguration condition, the base station issues the reconfiguration signaling to the UE, in order to ensure that the UE can correctly receive the downlink data transmitted by the base station during the period from when the reconfiguration signaling is issued to the UE to when the base station receives the reconfiguration completion signaling fed back by the UE, the base station determines the transmission times of the downlink data transmitted to the UE by using the multiple redundancy version scheme, and transmits the downlink data to the UE by using the multiple redundancy version scheme according to the determined transmission times, and can ensure that the UE correctly receives the downlink data transmitted by the base station due to the transmission times determined by the base station, so that the base station does not need to analyze the decoding result of the downlink data fed back by the UE according to the old configuration parameters (such as the old ACK feedback mode) but defaults the decoding result of the downlink data fed back by the UE to correct reception after the base station transmits the data, therefore, the failure of signaling reconfiguration caused by decoding the downlink decoding result transmitted by the UE by the base station by adopting wrong configuration parameters (old ACK feedback mode) is avoided. In addition, if the signaling reconfiguration fails, the base station needs to perform signaling reconfiguration with the UE again, so as to reduce the service transmission rate between the base station and the UE.

Detailed Description
The method and the device aim to solve the technical problems that when the base station reconfigures the signaling for the UE, signaling reconfiguration between the base station and the UE fails and the service rate is reduced due to the fact that a switching blind area of reconfiguration parameters exists between the base station and the UE in the prior art. An embodiment of the present invention provides a signaling reconfiguration processing method as shown in fig. 3, where a specific flow includes:
step 301, when determining that the UE meets the signaling reconfiguration condition, the base station issues a reconfiguration signaling to the UE;
step 302, a base station determines the transmission times of downlink data transmitted to UE by adopting a multi-redundancy version mode;
step 303, the base station transmits downlink data to the UE in a multi-redundancy version mode according to the determined transmission times, so that the UE correctly receives the transmitted downlink data;
step 304, the base station receives the reconfiguration complete signaling fed back by the UE;
and 305, the base station stops adopting a multi-redundancy version mode to transmit downlink data to the UE according to the reconfiguration completion signaling.
In the above method flow of the embodiment of the present invention, when the base station determines that the UE satisfies the signaling reconfiguration condition, the base station issues the reconfiguration signaling to the UE, in order to ensure that the UE can correctly receive the downlink data transmitted by the base station during the period from when the reconfiguration signaling is issued to the UE to when the base station receives the reconfiguration completion signaling fed back by the UE, the base station determines the transmission times of the downlink data transmitted to the UE by using the multiple redundancy versions, and transmits the downlink data to the UE by using the multiple redundancy versions according to the determined transmission times, and because of the transmission times determined by the base station, the UE can be ensured to correctly receive the downlink data transmitted by the base station, thus, the base station does not need to analyze the decoding result of the downlink data fed back by the UE according to the old configuration parameters (such as the old ACK feedback mode) after the base station transmits the data packet to the UE for the last time according to the determined transmission times, but defa, in the prior art, when all the UEs decode correctly, the correct result is analyzed to be an erroneous result, so that, compared with the prior art, the above method flow avoids the signaling reconfiguration failure caused by the base station decoding the downlink decoding result transmitted by the UE by using the erroneous configuration parameter (old ACK feedback mode). In addition, if the signaling reconfiguration fails, the base station needs to perform signaling reconfiguration with the UE again, so as to reduce the service transmission rate between the base station and the UE.
The above process flow is further described below.
In step 301, the signaling reconfiguration condition is a reconfiguration condition of carrier aggregation or a reconfiguration condition of carrier deletion. The carrier aggregation reconfiguration refers to newly building a carrier on the basis of the original number of carriers, and the reconfiguration of carrier deletion refers to deleting the carrier on the basis of the original number of carriers.
Before step 301, the method further comprises: and judging whether the UE meets the signaling reconfiguration condition. Specifically, the base station calculates whether the UE satisfies a signaling reconfiguration condition for carrier aggregation or carrier deletion according to other parameters such as GBR (guaranteed Bit Rate) satisfaction, long-term throughput, MBR (Maximum Bit Rate, upper limit of Rate reached under sufficient resources), AMBR (Aggregated Maximum Bit Rate), and Block Error Rate BLER (Block Error Rate) of the UE.
Step 301 specifically includes: when the UE is determined to meet the reconfiguration condition of carrier aggregation, issuing a reconfiguration instruction of carrier aggregation to the UE; or when the UE is determined to meet the reconfiguration condition of carrier deletion, issuing a reconfiguration instruction of carrier deletion to the UE.
In step 301, the reconfiguration command includes downlink configuration parameters, such as a new ACK feedback mode, to be reconfigured for the UE.
Further, after step 301, the method further includes: and when the base station issues the reconfiguration signaling to the UE, starting signaling tracking operation of the reconfiguration signaling.
Specifically, when the RRC layer of the base station issues the reconfiguration signaling to the UE, the RRC layer of the base station invokes the MAC layer of the base station according to the reconfiguration instruction, and sends a first control instruction to the MAC layer of the base station, where the first control instruction is used to instruct the MAC layer of the base station to start a signaling tracking operation on the reconfiguration signaling. For example, as shown in fig. 4, a signaling tracking processing module 401 and an HARQ processing module 402 are arranged on the MAC layer of the base station, and after the MAC layer of the base station receives the first control instruction, the signaling tracking processing module 401 is configured to perform a signaling tracking operation on the reconfiguration signaling.
Further, step 302 specifically includes: and the RRC layer of the base station sends a third control instruction to the MAC of the base station according to the reconfiguration instruction, wherein the third control instruction is used for indicating the MAC layer of the base station to determine the transmission times of transmitting downlink data to the UE in a multi-redundancy version mode according to the measurement parameters reported by the UE and the transmission mode when the UE meets the signaling reconfiguration condition. For example, as shown in fig. 4, the HARQ processing module 402 disposed on the MAC layer of the base station is configured to perform: and according to parameters such as the error rate BLER of the UE reported by the UE, a CQI value (Channel Quality Indication) reported by the UE and the like, determining the current transmission mode when the UE meets the signaling reconfiguration condition, and executing the calculation of the transmission times of the multiple redundancy versions.
The multi-redundancy version transmission refers to that a base station sends downlink data of a plurality of redundancy versions to UE, the UE receives the downlink data of the plurality of redundancy versions and combines the downlink data, even if the UE does not decode successfully for the first transmitted data, the UE can reduce the coding rate of a channel after combining the received downlink data of the plurality of redundancy versions, thereby realizing higher decoding success rate and ensuring the correctness of the downlink data. The principle is as follows: if the first transmission UE fails to decode, the channel coding rate can be reduced by retransmitting more redundant bits, thereby improving the decoding success rate. And if the redundant bit added with retransmission still cannot be decoded normally, retransmitting again. With the increase of retransmission times, redundant bits are continuously accumulated, and the channel coding rate is continuously reduced, so that a better decoding effect can be obtained.
In the HARQ transmission modes of a plurality of redundancy versions, the redundancy versions of the retransmission are different, the channel coding redundancy version of each retransmission is predefined well, extra signaling support is not needed, the robustness is enhanced, and the deletion mode of the coded redundancy bits is designed elaborately, so that the deleted code words are complementary and equivalent. Therefore, the combined code word can cover the bit in the FEC (Forward Error Correction) code, so that the decoding information becomes more comprehensive, and the receiving end is more favorable for correct decoding.
In summary, in step 302, the number of transmissions of multiple redundancy versions is determined, so that the UE can be ensured to correctly decode the downlink data transmitted according to the redundancy versions. For the UE with better signal-to-noise ratio, the base station only needs to send downlink data once, so that the UE can correctly decode the downlink data, and for the UE with poorer signal-to-noise ratio, the base station can correctly decode the transmitted downlink data by calculating the number of downlink data with different redundancy versions needing to be sent.
In step 303, the base station transmits downlink data to the UE in a multi-redundancy version manner according to the transmission times determined by the HARQ processing module 402 of the MAC layer before the MAC layer and the PHY layer of the base station receive the reconfiguration complete signaling fed back by the UE, and thus, after the base station transmits a data packet to the UE for the last time according to the determined transmission times, the base station does not need to analyze the downlink data decoding result fed back by the UE according to the old carrier configuration parameter, but defaults the downlink data decoding result fed back by the UE to correct reception, thereby avoiding a decoding error caused by decoding the downlink data decoding result transmitted by the UE by the base station using the old carrier configuration parameter and a reconfiguration failure caused by the decoding error.
In step 304, the step of receiving the reconfiguration complete signaling fed back by the UE by the base station includes: the PHY layer and the MAC layer of the base station receive the reconfiguration complete signaling fed back by the UE firstly, at the moment, the MAC layer and the PHY layer of the base station do not know that the packet data is signaling data, the RRC layer sent to the base station receives the reconfiguration complete instruction through the MAC layer and the PHY layer of the base station, the RRC layer of the base station analyzes the reconfiguration complete signaling fed back by the UE, and the RRC layer of the base station analyzes the reconfiguration complete signaling fed back by the UE and informs the MAC layer and the PHY layer of the base station.
The reconfiguration completion signaling fed back by the UE is that after the UE receives the reconfiguration signaling, the MAC layer and the PHY layer of the UE only analyze air interface data of the signaling, the MAC layer and the PHY layer of the UE do not know that the received signaling data is signaling data, the RRC layer of the UE analyzes reconfiguration information of the reconfiguration signaling, and then the RRC layer of the UE sends the reconfiguration completion signaling to the base station side through the MAC layer and the PHY layer of the UE. For example, the reconfiguration information analyzed by the UE from the reconfiguration signaling includes a new ACK feedback mode reconfigured for the UE, and the RRC layer of the UE informs the MAC layer and the PHY layer of the UE to transmit the downlink data decoding result to the base station in the new ACK feedback mode.
Further, after step 304, the method further includes:
and the RRC layer of the base station sends a fourth control instruction to the MAC layer of the base station according to the reconfiguration completion signaling, wherein the fourth control instruction is used for indicating the MAC layer of the base station to acquire downlink configuration parameters reconfigured by the UE and sending the acquired downlink configuration parameters to the PHY layer of the base station.
When the base station determines that the UE meets the carrier reconfiguration condition, the base station reconfigures the carrier number for the UE and reschedules data to the UE according to the current new carrier number of the channel, if the current channel is configured by a single carrier after the carrier reconfiguration, the base station only schedules the data of one carrier for the UE, and if the current channel is configured by multiple carriers, the base station schedules the data to the UE by adopting a carrier aggregation technology.
Specifically, after the RRC layer of the base station receives the reconfiguration complete signaling, the MAC layer of the base station is instructed to obtain the scheduling data rescheduled by the base station for the UE from the scheduler, and the downlink configuration parameter of the UE is calculated according to the scheduling data rescheduled for the UE.
For example, as shown in fig. 4, the HARQ processing module 402 disposed on the MAC layer of the base station is further configured to acquire scheduling data rescheduled by the base station for the UE from the scheduler, and calculate a downlink configuration parameter of the UE according to the scheduling data rescheduled for the UE, where the downlink configuration parameter includes an ACK feedback mode reconfigured for the UE.
After step 304, the method further comprises: and when receiving the reconfiguration completion signaling fed back by the UE, the base station closes the signaling tracking operation of the reconfiguration signaling.
Specifically, when the RRC layer of the base station receives the reconfiguration complete signaling fed back by the UE, the RRC layer of the base station invokes the MAC layer of the base station according to the received reconfiguration complete signaling, and sends a second control instruction to the MAC layer of the base station, where the second control instruction is used to instruct the MAC layer of the base station to close the signaling tracking operation on the reconfiguration signaling.
For example, after the MAC layer of the base station receives the second control instruction, the signaling tracking processing module arranged on the MAC layer of the base station is further configured to execute: and closing the signaling tracking operation of the reconfiguration signaling.
After step 305, the method further comprises: and the RRC layer of the base station sends a fifth control instruction to the PHY layer of the base station, wherein the fifth control instruction is used for instructing the PHY layer of the base station to decode a downlink data decoding result fed back by the UE according to the downlink configuration parameters.
For example, a PHY layer of the base station is provided with a decoding processing module, and the decoding processing module is configured to decode a downlink data decoding result fed back by the UE according to the downlink configuration parameter, for example, decode a downlink data decoding result subsequently fed back by the UE according to a new ACK feedback mode reconfigured for the UE.
In the above embodiment, as shown in fig. 5, the functional modules of the RRC layer of the base station include a reconfiguration condition determining module 501, a signaling adapter module 502, a transceiver module 503, a scheduler 504, and a processor 505.
A reconfiguration condition determining module 501, configured to determine whether the UE meets the signaling reconfiguration condition.
A signaling adapter module 502, configured to, when it is determined that the UE satisfies the signaling reconfiguration condition: issuing reconfiguration signaling to the UE; sending a first control instruction to an MAC layer of the base station, and indicating the MAC layer of the base station to start a signaling tracking operation of a reconfiguration signaling; and sending a third control instruction to the MAC of the base station, and indicating the MAC layer of the base station to determine the transmission times of the downlink data transmitted to the UE by adopting a multi-redundancy version mode.
The signaling adapter module 502 is further configured to, when receiving the reconfiguration complete signaling fed back by the UE: sending a second control instruction to the MAC layer of the base station, wherein the second control instruction is used for indicating the MAC layer of the base station to close the signaling tracking operation of the reconfiguration signaling; sending a fourth control instruction to the MAC layer of the base station, instructing the MAC layer of the base station to acquire downlink configuration parameters reconfigured by the UE, and sending the acquired downlink configuration parameters to the PHY layer of the base station;
the signaling adapter module 502 is further configured to send a fifth control instruction to the PHY layer of the base station when stopping transmitting downlink data to the UE in the multi-redundancy version mode, and instruct the PHY layer of the base station to decode a downlink data decoding result fed back by the UE according to the downlink configuration parameter.
A transceiver module 503, configured to issue a reconfiguration signaling to the UE when it is determined that the UE meets the signaling reconfiguration condition; and receiving the reconfiguration completion signaling fed back by the UE.
And the scheduler 504 is configured to reconfigure the number of carriers for the UE when the base station determines that the UE meets the carrier reconfiguration condition, and reschedule data to the UE according to the current new number of carriers of the channel.
A processor 505, configured to transmit downlink data to the UE in a multi-redundancy version mode after issuing the reconfiguration signaling to the UE; and stopping transmitting the downlink data to the UE by adopting a multi-redundancy version mode after receiving the reconfiguration finishing signaling fed back by the UE.
Preferably, the downlink configuration parameter in the foregoing embodiment includes an ACK feedback mode reconfigured for the UE when the base station performs signaling reconfiguration. At this time, the technical problems that carrier signaling reconfiguration failure and service rate reduction between the base station and the UE are caused by a switching blind area of an ACK feedback mode between the base station and the UE when the base station reconfigures the carrier for the UE in the prior art can be solved based on the method and the flow of the invention. In order to avoid the blind zone in the ACK feedback mode switching, the base station transmits the downlink data by adopting the multi-redundancy version transmission, so that the accuracy of the downlink data received by the UE can be ensured, the correct transmission of the carrier reconfiguration signaling is ensured, the problem of downlink decoding errors caused by the blind zone is solved, and the requirement of ensuring that the data service does not lose the rate is met. In addition, the signaling reconfiguration process can continue to perform uplink and downlink services for the UE, so that the problem of rate reduction caused by channel reconfiguration is avoided, and the uplink and downlink rates can be kept stable.
The invention is also suitable for the signaling reconfiguration blind area involved in the uplink ACK/NACK (Negative acknowledgement) signaling transmission, new data indication, downlink resource allocation signaling transmission and downlink data retransmission. The invention is also suitable for processing the blind area caused by other signaling configuration.
The method and the process are applied to HARQ signaling reconfiguration under multi-carrier configuration, and can be used for solving the technical problems of signaling reconfiguration failure between the base station and the UE and service rate reduction caused by the switching blind area of an ACK feedback mode between the base station and the UE when the base station reconfigures the signaling of carrier aggregation or carrier deletion for the UE. In the process of the blind zone occurring in the ACK feedback mode switching, the base station transmits the downlink data by adopting the multi-redundancy version transmission, so that the accuracy of the downlink data received by the UE can be ensured, the correct transmission of the carrier reconfiguration signaling is ensured, the problem of downlink decoding errors caused by the blind zone is solved, and the requirement of the data service on not dropping the rate is ensured. The following describes a method flow of HARQ signaling reconfiguration under multi-carrier configuration, which is improved by the embodiments of the present invention. As shown in fig. 6, the method specifically includes the following steps:
step 1, a base station schedules data services for UE according to the number of carriers currently configured by the UE, and an MAC layer and a PHY layer of the base station analyze a downlink decoding result fed back by the UE according to an ACK feedback mode currently configured;
the number of carriers currently configured by the UE may be a single carrier or multiple carriers. The ACK feedback mode applicable to a single carrier is only bundling (bundled mode) and multiplex (multiplexing mode). The ACK feedback mode for at least 2 carriers adds format 1b with channel selection and format 3. Format 1b with Channel selection can support ACK feedback of 2 carriers, including configuring at most 4 PUCCH (physical uplink Control Channel) Format 1b resources (referred to as Channel), and selecting one of the resources to feed back ACK/NACK information. The Format3 supports ACK feedback of 5 carriers at most, feeds back ACK information of 20 bits at most, and feeds back the ACK information on the PUCCH resource dedicated to the Format 3.
If the current scene is a scene for configuring a carrier, the base station analyzes a downlink decoding feedback result transmitted by the UE by adopting an ACK feedback mode of bundling (binding mode) or multiplexing (multiplexing mode), and feeds back the analysis result to the UE by adopting a format of format 1a or format 1 b; if the current situation is a situation in which more than one carrier is configured, the base station performs carrier aggregation scheduling data for the UE, and the base station analyzes the downlink decoding feedback result according to the format 1b with channel selection or the ACK feedback mode of the format3, and in this situation, the UE combines the downlink decoding results of multiple carriers together and sends the combined downlink decoding result to the base station.
Step 2, the base station detects whether the UE meets the signaling reconfiguration condition of carrier addition or carrier deletion;
specifically, the base station calculates whether the UE currently satisfies a signaling reconfiguration condition for carrier aggregation or carrier deletion according to other parameters such as the current GBR satisfaction of the UE, long-term throughput, MBR/AMBR parameters, and a bit error rate (BLER) parameter.
Step 3, when the base station detects that the UE meets the condition of signaling reconfiguration of carrier addition or carrier deletion, the RRC layer of the base station sends a reconfiguration signaling to the UE;
when determining that the UE meets the reconfiguration condition of carrier aggregation, issuing a reconfiguration signaling of carrier aggregation to the UE, namely issuing a reconfiguration signaling newly established by a carrier; and when the UE is determined to meet the reconfiguration condition of carrier deletion, issuing a reconfiguration signaling of carrier deletion to the UE. When the base station determines that the UE meets the signaling reconfiguration condition, the base station configures the reconfiguration signaling of carrier addition or carrier deletion for the UE, and at the moment, the base station also configures the number of new carriers for the current channel, wherein the new carrier number configuration can be single carrier configuration or multi-carrier configuration. For example, the carrier number in step 1 is single carrier configuration, and the reconfiguration signaling sent to the UE is reconfiguration signaling for carrier aggregation, then the configuration of the new carrier number is multi-carrier configuration.
Step 4, when the RRC layer of the base station sends the reconfiguration signaling to the UE, the RRC layer of the base station informs the MAC layer to start the signaling tracking operation of the reconfiguration signaling;
wherein, the starting time for signaling tracing of the reconfiguration signaling is the time when the RRC layer issues the reconfiguration signaling.
Step 5, the RRC layer of the base station calls the MAC layer of the base station, and the MAC layer of the base station determines the transmission times of transmitting downlink data to the UE in a multi-redundancy version mode;
the MAC layer of the base station sends a third control instruction to the MAC of the base station according to a command issued by the RRC layer of the base station, that is, according to the reconfiguration instruction in the above embodiment, and calculates the transmission times of the multiple redundancy versions of the UE according to factors such as a bit error rate (BLER) reported by the UE, a CQI value reported by the UE, and a current transmission mode for transmitting downlink data. The current transmission mode for transmitting the downlink data refers to a transmission mode for transmitting the downlink data to the UE when the base station determines that the UE meets the signaling reconfiguration condition. For UE with better signal-to-noise ratio, the downlink data can be correctly decoded by only sending one time, and for UE with poorer signal-to-noise ratio, the downlink data of a plurality of different redundancy versions are sent by calculation.
Step 6, during the period of tracking the reconfiguration signaling by the MAC layer of the base station, the base station transmits downlink data to the UE in a multi-redundancy version mode according to the determined transmission times of the multi-redundancy versions;
the ending time of the MAC layer of the base station signaling-tracking the reconfiguration signaling in step 4 is the time when the RRC layer of the base station notifies the completion of the reconfiguration of the MAC layer signaling, that is, the RRC layer of the base station sends the second control instruction to the MAC layer of the base station in the above embodiment, and instructs the MAC layer of the base station to close the tracking operation of the reconfiguration signaling.
The base station transmits and sends downlink data of a plurality of redundancy versions to the UE in a multi-redundancy version mode according to the determined transmission times of the plurality of redundancy versions, so that the UE performs data merging after receiving the downlink data of the plurality of redundancy versions, and the correctness of the downlink data is ensured. Due to the determined transmission times, the UE can be ensured to correctly receive the downlink data transmitted by the base station, so that the base station does not need to analyze the downlink data decoding result fed back by the UE according to the old carrier configuration parameters after the base station transmits the data packet to the UE for the last time according to the determined transmission times, but defaults the downlink data decoding result fed back by the UE to be correctly received, and therefore decoding errors caused by the fact that the base station decodes the downlink data decoding result transmitted by the UE by using the old carrier configuration parameters and reconfiguration failures caused by the decoding errors are avoided.
Step 7, the UE receives the reconfiguration signaling sent by the base station, analyzes the reconfiguration information in the reconfiguration signaling, including a new ACK feedback mode, and informs the MAC layer and the PHY layer of the UE to feed back a downlink decoding result to the base station side by adopting the new ACK feedback mode;
when the UE receives downlink data of multiple redundancy versions sent by a base station, an MAC layer and a PHY layer of the UE adopt a new ACK feedback mode to feed back a downlink decoding result to the base station side;
step 8, the RRC layer of the base station receives the downlink data decoding result fed back by the UE step, but does not analyze the downlink decoding feedback result of the UE, and automatically treats the downlink decoding result fed back by the UE for the downlink data of the last version as ACK when determining to transmit the downlink data of the last version to the UE only according to the transmission times of the multiple redundancy versions of the downlink data;
during the period of tracking the reconfiguration signaling by the MAC layer of the base station, sending downlink data of a plurality of redundancy versions to the UE, and ensuring the correctness of the downlink data, when the base station finishes sending the downlink data of the last version and receives the downlink decoding result which is fed back by the UE and aims at the downlink data of the last version, the decoding result which is fed back by the UE and aims at the downlink data of the last version is defaulted to be correct receiving, so that the problem of decoding errors caused by the fact that the MAC layer and the PHY layer of the base station adopt an incorrect ACK feedback mode to analyze the downlink decoding result is avoided.
Step 9, the UE feeds back a reconfiguration completion instruction to the base station through the MAC layer and the PHY layer of the UE;
step 10, the RRC layer of the base station receives the reconfiguration complete signaling fed back by the UE, and executes, according to the received reconfiguration complete signaling: stopping transmitting downlink data to the UE in a multi-redundancy version mode; sending a second control instruction to the MAC layer of the base station, and indicating the moment when the MAC layer of the base station closes the tracking operation of the reconfiguration signaling; and re-scheduling data to the UE according to the current new carrier number of the channel;
rescheduling data to the UE means: if the current configuration is single carrier configuration, the base station only dispatches data of one carrier to the UE, and if the current configuration is multi-carrier configuration, the base station dispatches data to the UE by adopting a carrier aggregation technology;
step 11, the RRC layer of the base station sends a command to inform the completion of the reconfiguration of the MAC layer of the base station according to the received reconfiguration completion signaling; the RRC layer of the base station sends a fourth control instruction to the MAC layer of the base station according to the reconfiguration completion signaling, instructs the MAC layer of the base station to acquire downlink configuration parameters reconfigured by the UE, and sends the acquired downlink configuration parameters to the PHY layer of the base station;
the MAC layer of the base station acquires scheduling data which is re-scheduled for the UE by the base station through a scheduler, downlink configuration parameters which are re-configured for the UE are determined according to the acquired scheduling data, and the MAC layer of the base station side sends the determined downlink configuration parameters to the PHY layer of the base station; and the downlink configuration parameters comprise a new ACK feedback mode reconfigured for the UE.
Step 12, the RRC layer of the base station sends a command to inform the completion of the reconfiguration of the PHY layer according to the received reconfiguration completion signaling;
and the RRC layer of the base station sends a fifth control instruction to the PHY layer of the base station according to the reconfiguration completion signaling, and instructs the PHY layer of the base station to decode a downlink data decoding result fed back by the UE according to the downlink configuration parameters, namely, a new ACK feedback mode is adopted to decode the downlink data decoding result fed back by the UE.
And the PHY layer of the base station receives the downlink configuration parameters sent by the MAC layer of the base station, and analyzes the downlink decoding result fed back by the UE after the step 10 according to the new ACK feedback mode included in the downlink configuration parameters.
Wherein, the downlink decoding result fed back by the UE after step 10 refers to the downlink decoding result fed back by the UE according to the new ACK feedback mode after the base station stops transmitting downlink data to the UE in the multi-redundancy version mode and resumes the normal transmission mode, and after transmitting downlink data to the UE according to the normal transmission mode.
In the above method flow of the embodiment of the present invention, when the base station determines that the UE satisfies the signaling reconfiguration condition, the base station issues the reconfiguration signaling to the UE, in order to ensure that the UE can correctly receive the downlink data transmitted by the base station during the period from when the reconfiguration signaling is issued to the UE to when the base station receives the reconfiguration completion signaling fed back by the UE, the base station determines the transmission times of the downlink data transmitted to the UE by using the multiple redundancy versions, and transmits the downlink data to the UE by using the multiple redundancy versions according to the determined transmission times, because of the transmission times determined by the base station, the UE can be ensured to correctly receive the downlink data transmitted by the base station, thus, after the base station transmits a data packet to the UE for the last time, the base station does not need to analyze the decoding result of the downlink data fed back by the UE according to the old ACK feedback mode but defaults to correctly receive the decoding result, therefore, carrier reconfiguration failure caused by decoding of the downlink decoding result transmitted by the UE by the base station by adopting an incorrect ACK feedback mode is avoided.
