Data transmission control method and equipment
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a data transmission control method and device.
Background
In R8/9 of an LTE-a (Long Term Evolution-Advanced) system, a physical layer standard defines seven UL/DL (i.e., uplink/downlink) configurations for a TDD (Time Division duplex) system, as shown in table 1, where D represents a DL (downlink) subframe, U represents an UL (uplink) subframe, and S represents a special subframe of the TDD system. The tdd ul/DL configuration of each cell is determined and the terminal is notified by the base station through a broadcast message.
Table 1: TDD UL/DL configurations
Compared with the LTE system, the peak rate of the LTE-A system is greatly improved, and the requirements are that the downlink speed is 1Gbps and the uplink speed is 500 Mbps. Meanwhile, the LTE-A system has good compatibility with the LTE system. Based on the needs of increasing peak rate, being compatible with the LTE system, and fully utilizing spectrum resources, the LTE-A R10 system introduces CA (Carrier Aggregation) technology.
The carrier aggregation technique allows a terminal to operate simultaneously on multiple cells, which may be contiguous or non-contiguous in the frequency domain, and the bandwidths of the individual cells may be the same or different. To remain compatible with LTE systems, the maximum bandwidth per cell is limited to 20 MHz. Currently, it is generally considered that the cell format of a ue aggregation is 5 at maximum.
In a carrier aggregation system, cells (cells) configured by a base station to a terminal may all be referred to as serving cells (serving cells), but functions of different serving cells may not be completely the same, so the LTE-a system further divides the serving cells:
PCell (Primary Cell): only one cell among a plurality of cells aggregated by the terminal is defined as a PCell, and the PCell is selected by the base station and configured to the terminal through a Radio Resource Control (RRC) signaling. Only the PCell is configured with a PUCCH (Physical uplink control Channel).
SCell (Secondary Cell): all cells except the Pcell among all cells aggregated by the terminal are scells.
In addition, according to whether different uplink Timing advances are needed to be used, a plurality of serving cells aggregated by one terminal may be further divided into a plurality of TAGs (Timing Advanced Group, Timing advance Group). Among them, a TAG containing a PCell is called pTAG (primary TAG), and a TAG containing only a SCell is called sstag (secondary TAG).
In order to implement cell switching between different frequencies or different systems, the system needs to configure the terminal to stop data transmission and reception in the current working frequency band within a certain time period, and adjust the transceiver to measure the channel quality of the different frequency or different system cell, where the time period is called Measurement Gap (Measurement Gap).
The pattern of the Measurement gap in the LTE system is shown in table 2:
table 2: terminal supported gap pattern configuration
In a CA in an R10 system, a terminal measures whether a certain frequency point needs to be configured with a Measurementgap or not, and the terminal can indicate the frequency point to a base station in a capability reporting mode, wherein the capability is related to the capability of the terminal. Whether the Measurement gap is needed or not when the different frequency or the different system Measurement indicated in the terminal capability report signaling is reported based on bandcombination, that is, the terminal reports whether the Measurement gap is needed or not when the terminal works in the bandcombination based on each bandcombination. The base station performs Measurement gap configuration according to the Measurement gap capability reported by the terminal, and the Measurement gap is configured on the basis of each terminal at present, and certainly can also be configured on the basis of each carrier.
During the Measurement gap, the terminal needs to adjust the transceiver to measure the specified pilot frequency or inter-system frequency point, so the uplink/downlink transmission on the current serving cell needs to be interrupted. In the R10 system and the previous version system, the uplink and downlink transmission interruption time caused by the Measurement gap is determined as follows:
(1) FDD (Frequency Division Duplex) system
Descending: the downlink data transmission interruption time caused by the Measurement gap is equal to MGL;
ascending: the interruption time of uplink data transmission caused by Measurement gap is equal to MGL +1 ms.
(2) TDD system
Descending: the downlink data transmission interruption time caused by the Measurement gap is equal to MGL;
ascending: uplink data transmission by Measurement gap is related to TDD UL/DL configuration:
for FDD systems, the uplink transmission interruption time caused by the Measurement gap is: the first subframe after MGL + MGL;
for a TDD system, if the subframe before the Measurement gap is a DL subframe and the first subframe after the Measurement gap is a UL subframe, the uplink transmission interruption time caused by the Measurement gap is: the first subframe after MGL + MGL; the uplink transmission interruption caused by Measurement gap for other cases is MGL.
The reason why the interruption time of uplink transmission caused by the Measurement gap may be longer than the interruption time of downlink transmission is that the uplink needs to be sent in advance, and thus if the first subframe after the Measurement gap is UL and uplink transmission is allowed, the Measurement result may be affected.

Detailed Description
For a terminal supporting aggregation of multiple downlink carriers, there may be multiple receivers, and therefore, when the terminal is to perform inter-frequency or inter-system (hereinafter, "inter-frequency or inter-system" is referred to as "inter-frequency/inter-system") measurement, in order to reduce the impact on data transmission, only one of the receivers may be adjusted to perform the inter-frequency/inter-system measurement, while the other receivers are not adjusted, and data transmission may be continuously maintained, thereby improving system throughput.
However, at present, a network side device, such as a base station, cannot know a receiver structure of a terminal, and therefore cannot determine which transceiver the terminal adjusts to perform inter-frequency/inter-system Measurement, and thus cannot determine which cells have data transmission affected by Measurement gap.
In order to reduce the influence of the Measurement gap on data transmission and improve the system throughput, the embodiment of the invention provides a scheme for determining a cell which can maintain data transmission during the Measurement gap, and the cell indication information which is influenced by the Measurement gap (or not influenced by the Measurement gap) is carried in the capability information reported to the base station by the terminal in an explicit or implicit manner, so that the base station can determine which cell data transmission aggregated by the terminal can not be influenced when the Measurement gap occurs.
The following describes embodiments of the present invention in detail with reference to several specific embodiments.
Example one
This embodiment describes a scheme in which, in an LTE-A R10 system, a UE (User Equipment or terminal) indicates a cell that needs to interrupt data transmission or a cell that needs to maintain data transmission by using an explicit indication manner, and an eNB (evolution NodeB, evolved node B, i.e., base station) performs Measurement gap configuration by using a UE-based manner.
As shown in fig. 1, the procedure of indicating the cell requiring/not requiring to interrupt data transmission by using the explicit indication mode may include:
step 101, the UE reports measurement capability information to the eNB, where a display mode is adopted to indicate a cell that needs to interrupt data transmission during a measurement entry gap, or a cell that needs to maintain data transmission, that is, the reported capability information carries indication information of the cell that needs to interrupt data transmission, or indication information of the cell that needs to maintain data transmission.
In this embodiment, the UE is required to add cell indication information that needs to interrupt data transmission and corresponds to the Measurement gap, or to add cell indication information that needs to maintain data transmission and corresponds to the Measurement gap, on the basis of reporting content of the existing Measurement gap capability in the R10 system. The cell indication information may be represented by a band or a band list, and one band may correspond to one or more cells.
In step 102, the eNB configures a Measurement gap for the UE in a UE-based manner, and the specific implementation of the process may adopt the prior art.
After that, during the Measurement gap, the eNB determines, according to the cell indication information that needs to interrupt data transmission during the Measurement entry gap and is carried in the capability information reported by the UE, or the cell indication information that needs to maintain data transmission, which cells need to interrupt data transmission (such as downlink data transmission or uplink/downlink data transmission) to the UE during the Measurement gap, and which cells maintain data transmission (such as downlink data transmission or uplink/downlink data transmission) to the UE, and performs data transmission processing on the UE accordingly. During the Measurement gap, the UE determines a cell that needs to interrupt data transmission or a cell that needs to maintain data transmission during the gap according to the Measurement capability information reported by the UE, and stops or maintains data transmission (such as downlink data reception or uplink/downlink data transmission) on the corresponding cell according to the cell that needs to interrupt data transmission during the gap.
On the basis of the first embodiment, the following optimization processing may be performed: in a band or a band list which needs to interrupt data transmission and is reported by the UE, or in a band or a band list which needs to maintain data transmission, frequency band indication information for indicating a high frequency band or a low frequency band is set aiming at all or part of the indicated bands to indicate that the data transmission is interrupted or maintained on a cell corresponding to the high frequency band or the low frequency band of the band. The frequency band indication information may be 1bit indication information.
Taking the case that the frequency band indication information value is 0 to indicate a low frequency band, and the value is 1 to indicate a high frequency band as an example, if the UE reports a band or a band list that needs to interrupt data transmission, it indicates that data transmission needs to be interrupted on the low frequency band of the band for the band in which the frequency band indication information value is set to be 0, and indicates that data transmission needs to be interrupted on a cell corresponding to the high frequency band of the band for the band in which the frequency band indication information value is set to be 1. Accordingly, during the Measurementgap, the eNB and the UE interrupt data transmission between each other in the cell corresponding to the low band of the band in which the band indication information having a value of 0 is set, and interrupt data transmission between each other in the cell corresponding to the high band of the band in which the band indication information having a value of 1 is set.
Similarly, if the UE reports the band or the band list that needs to maintain data transmission, it indicates that data transmission needs to be maintained on the low frequency band of the band for the band in which the frequency band indication information with the value of 0 is set, and indicates that data transmission needs to be maintained on the cell corresponding to the high frequency band of the band for the band in which the frequency band indication information with the value of 1 is set. Accordingly, during the Measurement gap, the eNB and the UE maintain data transmission between each other in a cell corresponding to a low band of the band in which the band indication information having a value of 0 is set, and maintain data transmission between each other in a high band of the band in which the band indication information having a value of 1 is set.
Example two
This embodiment describes a scheme in which, in an LTE-A R10 system, a UE indicates a cell that needs to interrupt data transmission or a cell that needs to maintain data transmission in an explicit indication manner, and an eNB performs Measurement gap configuration in a band-based or cell-based manner.
As shown in fig. 2, the procedure of indicating the cell requiring/not requiring interruption of data transmission by using the explicit indication mode may include:
in step 201, the UE reports measurement capability information to the eNB, where a display mode is used to indicate a cell that needs to interrupt data transmission during the measurement entry gap, or a cell that needs to maintain data transmission, that is, the reported capability information carries indication information of the cell that needs to interrupt data transmission, or indication information of the cell that needs to maintain data transmission. The step is implemented in the same way as in the first embodiment.
In step 202, the eNB configures Measurementgap for the UE in a band or cell based manner. When configuring the Measurement gap, the configuration information sent to the UE needs to carry a band or a cell identifier, which needs to interrupt or maintain data transmission, corresponding to the Measurement gap.
After that, the eNB determines, during the Measurement gap, a band and a cell identifier that need to interrupt or maintain data transmission during the Measurement gap according to the Measurement gap configured for the UE, and during the terminal executing the Measurement gap, the eNB interrupts or maintains data transmission (such as downlink data transmission or uplink/downlink data transmission) to the UE on the cell. During the Measurement gap, the UE stops data transmission (such as downlink data reception or uplink/downlink data transmission) on the band or the cell configured with the Measurement gap according to the Measurement gap configured by the eNB for the UE, and maintains data transmission on other cells aggregated or aggregated and activated by the UE.
On the basis of the second embodiment, the following optimization processing may be performed: in a band or a band list which needs to interrupt data transmission and is reported by the UE, or in a band or a band list which needs to maintain data transmission, frequency band indication information for indicating a high frequency band or a low frequency band is set aiming at all or part of the indicated bands to indicate that the data transmission is interrupted or maintained on a cell corresponding to the high frequency band or the low frequency band of the band. The frequency band indication information may be 1bit indication information. The specific setting method and meaning are the same as those in the first embodiment, and are not described herein again.
It can be seen from the above first and second embodiments that, when reporting the terminal capability information, the UE reports, to the base station, the cell indication information that needs to interrupt data transmission or the cell indication information that needs to maintain data transmission during the inter-frequency/inter-system measurement, so that the base station can determine which cells need to interrupt data transmission for the terminal and maintain data transmission for which cells when the terminal performs the inter-frequency/inter-system measurement, thereby reducing the influence on the data transmission of the terminal.
EXAMPLE III
In this embodiment, in the LTE-A R10 system, a cell in which data transmission needs to be interrupted during the inter-frequency/inter-system measurement performed by the UE is agreed in advance between the UE and the eNB.
The agreed rules include, but are not limited to, one of the following:
in a band set aggregated by the UE, data transmission (including downlink data reception, or uplink and downlink data transmission) on a cell corresponding to a band with the smallest, largest, or middle number is interrupted, and further, the band set does not include a band in which the PCell is located.
In a band set aggregated by the UE, data transmission (including downlink data reception, or uplink and downlink data transmission) on a cell corresponding to a band with the highest, lowest, or middle frequency point is interrupted, and further, the band set does not include a band in which the PCell is located.
In a band set aggregated by the UE, data transmission (including downlink data reception, or uplink and downlink data transmission) on a cell corresponding to a band having the smallest, largest, or middle celldex is interrupted, and further, the band set does not include a band in which the PCell is located.
In the band set aggregated by the UE, data transmission (including downlink data reception, or uplink/downlink data transmission) on cells corresponding to one or more bands other than the band where the PCell is located is interrupted.
One solution of this embodiment is: the UE reports the capacity by adopting the existing mode in the R10 system, and the reported capacity information carries bandcombination combination information supported by the UE. The eNB configures a Measurement gap for the UE in a UE-based manner. The eNB determines a cell which needs to be interrupted or needs to maintain data transmission according to a rule agreed with the UE during a Measurement gap, and interrupts or maintains data transmission (such as downlink data transmission or uplink/downlink data transmission) on the corresponding cell; the UE determines a cell in which data transmission needs to be interrupted or maintained according to a rule agreed with the eNB during the Measurement gap, and interrupts or maintains data transmission (such as downlink data reception or uplink/downlink data transmission) of the UE on the corresponding cell.
Another scheme of this embodiment is: the UE reports the capacity by adopting the existing mode in the R10 system, and the reported capacity information carries bandcombination combination information supported by the UE. The eNB determines the number of bands supported by the UE according to band combination information carried in the capability information reported by the UE, configures a Measurement gap for the UE in a band or cell-based mode, and carries band or cell indication information needing to interrupt or maintain data transmission in Measurement configuration information sent to the UE when the Measurement gap is configured. During the terminal performing inter-frequency/inter-system Measurement, the eNB interrupts or maintains data transmission (such as downlink data transmission or uplink/downlink data transmission) to the UE on the band or cell indicated in the Measurement gap configuration information and requiring to interrupt data transmission or maintain data transmission; the UE determines, during the Measurement gap, a band or a cell in which data transmission needs to be maintained or interrupted during the Measurement gap according to Measurement gap configuration information configured by the eNB for the UE, and maintains or interrupts data transmission (such as downlink data reception or uplink/downlink data transmission) on the corresponding band or cell.
Example four
In this embodiment, in the LTE-A R10 system, during a period of preassigned measurement gap between the UE and the eNB, a cell in which data transmission needs to be interrupted.
The agreed rules include, but are not limited to, one of the following:
in the TAG set aggregated by the UE, data transmission (including downlink data reception, or uplink/downlink data transmission) on a cell corresponding to the TAG with the smallest, largest, or middle number is interrupted, and further, no pTAG is included in the TAG set.
In a TAG set aggregated by the UE, data transmission (including downlink data reception, or uplink and downlink data transmission) on a cell corresponding to a TAG having a smallest, largest, or middle cellindex is interrupted, and further, the TAG set does not include a pTAG.
In the UE aggregated TAG set, interrupting data transmission (including downlink data reception, or uplink/downlink data transmission) on the cell corresponding to one or more TAGs other than pTAG.
One solution of this embodiment is: the UE reports the capability by using the existing method in the R10 system, and the capability information reported by the UE carries MTA (Multiple Time Alignment, Multiple timing advance) support capability information. The eNB configures a Measurement gap for the UE in a UE-based manner. The eNB determines a cell needing to interrupt or maintain data transmission according to a rule agreed with the UE during a Measurement gap, and interrupts or maintains data transmission (such as downlink data transmission or uplink/downlink data transmission) to the UE on the cell; during the Measurement gap, the UE determines a cell in which data transmission needs to be interrupted or maintained according to a rule agreed with the eNB, and the terminal either maintains data transmission on the cell (such as downlink data reception or uplink/downlink data transmission).
Another scheme of this embodiment is: the UE reports the capacity by adopting the existing mode in the R10 system, and the reported capacity information carries MTA support capacity information. The eNB determines the number of TAGs supported by the UE according to the MTA capability information carried in the capability information reported by the UE, configures Measurement gap for the UE in a TAG or cell-based mode according to the number of TAGs of the UE, and carries the TAG or cell information needing to interrupt or maintain data transmission in the Measurement configuration information sent to the UE when configuring the Measurement gap. During the terminal performing inter-frequency/inter-system Measurement, the eNB interrupts or maintains data transmission (such as downlink data transmission or uplink/downlink data transmission) to the UE on the TAG or the cell indicated in the Measurement gap configuration information and requiring interruption or maintenance of data transmission; during the Measurement gap, the UE determines a TAG or a cell, which needs to interrupt or maintain data transmission during the Measurement gap, according to the Measurement gap configuration information configured by the eNB for the UE, and interrupts or maintains data transmission (such as downlink data reception or uplink/downlink data transmission) on the corresponding TAG or cell.
EXAMPLE five
In this embodiment, in the LTE-A R10 system, during a period of preassigned measurement gap between the UE and the eNB, a cell in which data transmission needs to be interrupted.
The agreed rules include, but are not limited to, one of the following:
in the UE aggregated TDD configuration set, interrupting data transmission (such as downlink data reception or uplink/downlink data transmission) on a cell corresponding to the TDD configuration with the highest, lowest or middle TDD configuration number. Further, the TDD configuration set does not include the TDD configuration set in which the PCell is located.
In the UE aggregated TDD configuration set, interrupting data transmission (such as downlink data reception, or uplink/downlink data transmission) on the cell corresponding to the TDD configuration set having the smallest, largest, or middle Cellindex. Further, the TDD configuration set does not include the TDD configuration set in which the PCell is located.
In the UE aggregated TDD configuration set, data transmission (such as downlink data reception, or uplink/downlink data transmission) on a cell corresponding to one or more TDD configuration combinations that the PCell may use different TDD configurations is interrupted.
One solution of this embodiment is: the UE reports the capacity by adopting the existing mode in the R10 system, and the reported capacity information carries the multi-TDD configuration supporting capacity information. And the eNB configures the Measurementgap for the UE in a UE-based mode. The eNB determines a cell needing to interrupt or maintain data transmission according to a rule agreed with the UE during a Measurement gap, and interrupts or maintains data transmission (such as downlink data transmission or uplink/downlink data transmission) to the UE on the cell; during the Measurement gap, the UE determines a cell in which data transmission needs to be interrupted or maintained according to a rule agreed with the eNB, and interrupts or maintains data transmission (such as downlink data reception or uplink/downlink data transmission) on the cell.
Another scheme of this embodiment is: the UE reports the capacity by adopting the existing mode in the R10 system, and the reported capacity information carries the multi-TDD configuration supporting capacity information. The eNB determines the number of TDD configuration sets supported by the UE according to multi-TDD configuration support capability information carried in the capability information reported by the UE, configures Measurement gap of a different frequency/different system for the UE in a TDD configuration set or cell-based mode, and carries TDD configuration sets or cell information needing to interrupt or maintain data transmission in Measurement configuration information sent to the UE when the Measurement gap is configured. During the terminal performing inter-frequency/inter-system Measurement, the eNB interrupts or maintains data transmission (such as downlink data transmission or uplink/downlink data transmission) to the UE on the TDD configuration set or the cell indicated in the Measurement gap configuration information and requiring interruption or maintenance of data transmission; the UE determines, during the Measurement gap, a TDD configuration set or a cell in which data transmission needs to be interrupted or maintained during the Measurement gap according to Measurement configuration information configured by the eNB for the UE, and interrupts or maintains data transmission (such as downlink data reception or uplink/downlink data transmission) on the corresponding TDD configuration set or cell. .
As can be seen from the above third, fourth and fifth embodiments, by presetting a rule between the terminal and the base station to specify a cell in which data transmission needs to be interrupted during the inter-frequency/inter-system measurement performed by the terminal, the terminal and the base station can perform transmission control on the corresponding cell according to the preset rule during the inter-frequency/inter-system measurement performed by the terminal, thereby reducing the influence on data transmission of the terminal.
Based on the same technical concept, the embodiment of the invention also provides terminal equipment and base station equipment.
