To more fully understand those skilled in the art and realizing the present invention, referring to the drawings, by specific embodiment It is described in detail.

Embodiment one

As described below, the embodiment of the present invention provides a kind of downlink data control method.

The downlink data control method that the present embodiment is provided, generally can come real by the base station in GSM Apply, it is adaptable to various 4G systems, 5G systems.

The downlink data control method that base station is provided by the present embodiment, by the tune related to each UE being resident in cell Degree information is transmitted, and is able to detect that in order to each UE and judges whether this UE is scheduled for accordingly.

UE is by the downlink data monitor method provided in the embodiment of the present invention three, the first kind in real-time detection channel Control channel Resource Unit, and judge whether this UE is scheduled for accordingly.

Downlink data control method flow chart shown in reference picture 1, is described in detail below by way of specific steps：

S101, sets configured information.

Whether the configured information indicates currently have schedule information.

Because the configured information only needs to express "Yes" or "No", thus only need to 1 bit and be just enough to express, In the present embodiment, the configured information occupies 1 bit, and the configured information is indicated currently in the form of "Yes" or "No" Whether schedule information is had.In other embodiments, also it is not excluded for the possibility expressed with multiple bits.

Although it should be noted that whether the configured information can indicate currently have schedule information, the schedule information May not be corresponding with this UE (being also possible to dispatch other UE resided in same cell).Follow-up step S102 enables UE Enough determine therefrom that whether the UE being scheduled for is this UE.

S102, first treatment related to first mark of UE is carried out to configured information.

Wherein, first mark of the UE is unique marks of the UE in a cell or a wave beam.In an implementation Example in, UE first mark can be UE access cell when by base station be its distribution.

Configured information is carried after being processed through first by first kind control channel Resource Unit, and UE can be according to the first kind Information in control channel Resource Unit judges whether this UE is scheduled for.

In being processed first, first kind control channel Resource Unit needs to be mapped on REG, and the REG for being mapped is one In individual arrowband.Wherein, arrowband is a narrower frequency range (Frequency Region).UE only needs to sampling arrowband letter Number, the REG that first kind control channel Resource Unit is mapped to can be just found, can be according to the first kind control channel resource Information in unit judges whether this UE is scheduled for.Narrow band signal can carry out frequency-hopping transmissions, i.e., narrow band signal is in difference Subframe or slot transmission when using different frequency ranges.

Understood with reference to the analysis of background of invention part, in the prior art, the first mark is included in the CRC of DCI In, various schedule informations such as RB distribution, MSC are included in DCI, thus the bit that DCI takes is more, sends out in the channel The REG numbers used when sending are also more.

The present embodiment by the first of UE the mark from DCI independent separate out, i.e., no longer with DCI in other control information Mix, the bit number that first kind control Resource Unit takes is few, the REG numbers used when sending in the channel also compared with It is few, for example, for example can be 8 RE, in the case of including 4 RE in each REG, it is only necessary to 2 REG, far Less than the REG numbers that DCI is used in the channel.UE detects that the complexity of the first kind control Resource Unit in the present embodiment is far small In the complexity of detection DCI, it is thus possible to reduce UE for detecting the electricity that the process of schedule information is consumed.

First treatment can have number of ways to realize, for example：

In one embodiment, described first it is processed as：The first mark to configured information verification generation CRC and UE is carried out Scrambling, is used to identify the UE, then encoded.

UE is right using first mark of UE as the condition code of the UE after first kind control channel Resource Unit is detected Configured information and CRC are obtained after information decoding in first kind control channel Resource Unit, is carried out with CRC with first mark of UE Descrambling, you can in the case where configured information indicates "Yes", further determine that whether the UE being scheduled for is this UE.

In another embodiment, described first it is processed as：Coded modulation is simultaneously mapped to first kind control channel resource list In unit, then determine resource during first kind control channel Resource Unit used in physical channel according to first mark of UE Position and/or sequence, the first kind control channel Resource Unit for dispatching the corresponding UE of different first marks are believed in physics Different resource location and/or sequence are used in road.

Resource location that UE is used in the channel according to the first kind control channel Resource Unit that detects and/or Sequence determines whether scheduled UE is this UE, you can in the case where configured information indicates "Yes", further determines that and is adjusted The UE for spending is this UE.

Both examples above can make UE (in the case where configured information indicates "Yes") further determine that and be scheduled for UE whether be this UE.Compared to each advantageous, the former complexity is higher, but the REG numbers for using in the channel are less for both, after Person's complexity is relatively low, but the REG numbers for using in the channel are more.

S103, UE is sent to by the first kind control channel Resource Unit.

Specifically, for example, the first kind control channel Resource Unit can be passed through Physical Downlink Control Channel UE is sent to, or the first kind control channel Resource Unit is sent to UE by broadcast channel.

Each UE being resident in cell is able to detect that first kind control channel Resource Unit, with reference in abovementioned steps S102 Analysis understands that (at least two kinds approach are realized) each UE can be according in the first kind control channel Resource Unit for detecting Information, configured information indicate "Yes" in the case of, further determine that whether the UE being scheduled for is this UE.

In specific implementation, the first kind control channel Resource Unit only maps into the RE in predetermined arrowband, described First kind control channel Resource Unit sends in arrowband.

In specific implementation, narrow band signal carries out frequency-hopping transmissions, and narrow band signal is adopted in different subframes or slot transmission With different frequency ranges.

Understood with reference to the analysis of background of invention part, with continuing to develop for mobile communication technology, in order to realize Faster transmission rate, advanced communication system can have bigger bandwidth, such as the bandwidth under 5G systems can be 4G systems Under 10 times it is even more many, due to carry schedule information control channel Resource Unit be dispersed in whole bandwidth, therefore, UE detects that the process of schedule information is more complicated in the very big channel of bandwidth.

In the present embodiment, base station is when the first kind control channel Resource Unit is sent using only (in communication protocol) REG in predetermined arrowband, so that the process of UE detection schedule informations only needs to the predetermined arrowband (in communication protocol) of detection , consequently facilitating each UE detects schedule information from channel.Further, since the increase of channel total bandwidth do not interfere with it is predetermined The bandwidth of arrowband, thus each UE detects that the complexity of schedule information will not be with channel from (in communication protocol) predetermined arrowband The increase of total bandwidth and increase.

It should be noted that implication of " predetermined " one vocabulary up to " making a reservation in communication protocol " in the present invention.Predetermined is interior It is known to hold for the base station under the GSM and each UE.

Analysis to technical scheme more than can be seen that：In the present embodiment, configured information and first kind control are set Whether channel resource units, the configured information has the first of UE to mark with current in instruction channel in the form of "Yes" or "No" Know, the configured information only needs to occupy few bit and (only needs to express "Yes" or "No", thus 1 bit is Can), the configured information it is encoded and first treatment after by the first kind control channel Resource Unit carry, by channel (in communication protocol) predetermined position sends.Due to the program by the first of UE the mark from DCI independent separate out, i.e., not Mixed with other control information in DCI again, the bit number that first kind control Resource Unit takes is few, sends out in the channel The REG numbers used when sending are also less, reduce the complexity of UE detections, can reduce UE for detecting the process institute of schedule information The electricity of consumption.

Transmitting element 203, after performing operation in the first processing units 202, the first kind is controlled to believe Road Resource Unit is sent to UE, and each UE being resident in cell is able to detect that first kind control channel Resource Unit.

In specific implementation, first treatment can be：To configured information verification generation CRC and UE first identify into Row scrambling, is used to identify the UE, then encoded.

In specific implementation, first treatment can be：Coded modulation is simultaneously mapped to first kind control channel resource list In unit, then determine resource during first kind control channel Resource Unit used in physical channel according to first mark of UE Position and/or sequence, the first kind control channel Resource Unit for dispatching the corresponding UE of different first marks are believed in physics Different resource location and/or sequence are used in road.

Description to technical scheme more than can be seen that：In the present embodiment, first treatment can at least have two The approach of kind realizes that specifically, described first is processed as：The first mark to configured information verification generation CRC and UE is scrambled, It is used to identify the UE, then is encoded；Or described first be processed as：Coded modulation is simultaneously mapped to first kind control channel money In source unit, then determine during first kind control channel Resource Unit used in physical channel according to first mark of UE Resource location and/or sequence, for dispatching the first kind control channel Resource Unit of the corresponding UE of different first marks in thing Different resource location and/or sequence are used in reason channel.Two kinds of approach can make UE (indicate the situation of "Yes" in configured information Under) further determining that whether the UE being scheduled for is this UE, both compare, and the former complexity is higher, but uses in the channel REG numbers it is less, the latter's complexity is relatively low, but the REG numbers for using in the channel are more.

In specific implementation, the first kind control channel Resource Unit can only map into the RE in predetermined arrowband.

Description to technical scheme more than can be seen that：In the present embodiment, the first kind control channel resource list Unit only maps into the RE in predetermined arrowband, so that the process of UE detection schedule informations only needs to the predetermined arrowband of detection.

In specific implementation, the configured information can only occupy 1 bit, the configured information with "Yes" or Whether the form of "No" indicates current the first mark having corresponding to UE.

In specific implementation, the first kind control channel Resource Unit is sent into UE can be：By the first kind Control channel Resource Unit is sent to UE by Physical Downlink Control Channel, or by the first kind control channel resource list Unit is sent to UE by broadcast channel.

In specific implementation, the first kind control channel Resource Unit can be detected under IDLE state, if described Configured information in one class control channel Resource Unit indicates "Yes", then UE is transferred to CONNECTED states by IDLE state, or It is that UE starts to monitor paging information in IDLE state, wait is paged.

In specific implementation, the CONNECTED states of UE can include the sub- states of CONNECTED INACTIVE and The sub- states of CONNECTED ACTIVE, the first kind control channel is detected under the sub- states of CONNECTED INACTIVE Resource Unit, if the configured information in the first kind control channel Resource Unit indicates "Yes", UE is by CONNECTED states Under the sub- states of CONNECTED INACTIVE be transferred to sub- states of CONNECTED ACTIVE under CONNECTED states.

In specific implementation, UE and base are kept under the sub- states of CONNECTED ACTIVE of the UE under CONNECTED states Very first time Frequency Synchronization between standing, the sub- shapes of CONNECTED INACTIVE under IDLE state or CONNECTED states The second temporal frequency synchronization is kept under state, the very first time Frequency Synchronization and second temporal frequency synchronously have different Precision.Under the sub- states of CONNECTED INACTIVE of the UE under IDLE state or CONNECTED states, at the UE mosts of the time In narrow-band operation, the quantity of reference signal is limited to, therefore is also difficult to reach synchronization accuracy very high, and the data that UE is received and dispatched It is less, thus need not be very high synchronization accuracy requirement.

Description to technical scheme more than can be seen that：In the present embodiment, UE is under CONNECTED states The very first time Frequency Synchronization between UE and base station is kept under the sub- states of CONNECTED ACTIVE, in IDLE state or The second temporal frequency synchronization, the very first time are kept under the sub- states of CONNECTED INACTIVE under CONNECTED states Frequency Synchronization and second temporal frequency synchronously have different precision, and so, UE can be in IDLE state or CONNECTED Narrow band signal is received under the sub- states of CONNECTED INACTIVE under state, so that power saving.

Although it should be noted that whether the configured information can indicate currently have schedule information, the schedule information May not be corresponding with this UE (being also possible to dispatch other UE resided in same cell).Follow-up step S305 enables UE Enough determine therefrom that whether the UE being scheduled for is this UE.

S304, judges whether this UE is scheduled for according to the information related to first mark of UE.

UE real-time detection first kind control channel Resource Units, and can be according to the first kind control channel Resource Unit In information judge whether this UE is scheduled for.

Description to technical scheme more than can be seen that：In the present embodiment, configured information and first kind control are set Whether channel resource units, the configured information has the first of UE to mark with current in instruction channel in the form of "Yes" or "No" Know, the configured information only needs to occupy few bit and (only needs to express "Yes" or "No", thus 1 bit is Can), the configured information it is encoded and first treatment after by the first kind control channel Resource Unit carry, by channel (in communication protocol) predetermined position sends.Due to the program by the first of UE the mark from DCI independent separate out, i.e., not Mixed with other control information in DCI again, the bit number that first kind control Resource Unit takes is few, sends out in the channel The REG numbers used when sending are also less, reduce the complexity of UE detections, can reduce UE for detecting the process institute of schedule information The electricity of consumption.

Furthermore, it is possible to the first kind control channel Resource Unit is detected under IDLE state, if the first kind is controlled Configured information in channel resource units indicates "Yes", then UE is transferred to CONNECTED states by IDLE state, or UE starts Paging information is monitored in IDLE state, wait is paged.

The CONNECTED states of (can be defined in communication protocol) UE include the sub- states of CONNECTED INACTIVE and The sub- states of CONNECTED ACTIVE, the first kind control channel is detected under the sub- states of CONNECTED INACTIVE Resource Unit, if the configured information in the first kind control channel Resource Unit indicates "Yes", UE is by CONNECTED states Under the sub- states of CONNECTED INACTIVE be transferred to sub- states of CONNECTED ACTIVE under CONNECTED states.

When first between UE and base station is kept under the sub- states of CONNECTED ACTIVE of the UE under CONNECTED states Between Frequency Synchronization, when keeping second under the sub- states of CONNECTED INACTIVE under IDLE state or CONNECTED states Between Frequency Synchronization, the very first time Frequency Synchronization and second temporal frequency synchronously have different precision.UE is in IDLE Under the sub- states of CONNECTED INACTIVE under state or CONNECTED states, the UE mosts of the time are in narrow-band operation, receive It is limited to the quantity of reference signal, therefore is also difficult to reach synchronization accuracy very high, and the data of UE transmitting-receivings are less, therefore be not required to Synchronization accuracy that will be very high is required.
