Description

Method and device for controlling secondary carrier of dual carrier

technical field

The present invention relates to the field of downlink data services in the third-generation mobile communication technology, in particular to a method and device for controlling a secondary carrier of a dual carrier.

Background technique

In the HSDPA (High Speed Downlink Packet Access) technology in WCDMA (Wireless Code Division Multiple Access, wireless code division multiple access), the main Auxiliary carrier technology. The R8 protocol introduced the FDD (Frequency Division Duplex, Frequency Division Duplex) dual-cell (carrier) HSDPA function in March 2009, and the peak rate of the user equipment UE was increased to 2×21.6M=43.2M.

In order to improve the throughput of users, DC-HSDPA transmits data simultaneously through two adjacent carriers. For a dual-carrier UE, there are two downlink cells, one serving cell and one secondary serving cell, and one uplink cell. The serving cell has a corresponding uplink channel, while the secondary serving cell has no corresponding uplink channel. The serving cell has exactly the same capabilities as the previous single-carrier HSDPA cell. In the secondary serving cell, there are only physical channels required for HSDPA transmission, namely CPICH (Common Pilot Channel, Common Pilot Channel), HS-PDSCH (Physical Downlink Shared Channel , physical downlink shared channel (physical downlink shared channel) and HS-SCCH (Sharing Control Channel, shared control channel).

When the amount of UE data to be sent by the RNC (Radio Network Controller, radio network controller) side is large, the primary and secondary cells are used to send at the same time, which can bring great gains; and when the amount of data that the UE needs to send is relatively small, If the UE is activated by the secondary serving cell, unnecessary wireless resource overhead will be brought. At this time, the secondary serving cell of the UE may be deactivated, thereby saving battery power consumption of the UE. Because when the secondary serving cell is activated, the UE needs to receive downlinks from two cells, which consumes more power. When the uplink power of the UE is limited, if the UE is activated by the secondary serving cell, the secondary serving cell of the UE may also be deactivated at this time. The activation and deactivation of the secondary serving cell in the related art is notified to the UE through the high-speed shared control channel order (HS-SCCH order). However, frequent transmission of the HS-SCCH order will bring additional network control overhead and affect the system performance. performance.

Detailed ways

Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

The embodiment of the present invention mainly controls the secondary carrier of the dual-carrier terminal, so as to save radio resources and save battery power consumption of the UE. Wherein, the dual-carrier terminal refers to a terminal that supports dual-carrier technology. In the embodiment of the present invention, the scheduler of the base station (Node b) sends an HSSCCH order command to activate/deactivate the secondary serving cell of the UE under suitable conditions, and then control the secondary carrier of the UE. Based on this, a method and device for controlling a secondary carrier of a dual carrier are provided.

Example 1

Fig. 1 shows a flowchart of a method for controlling a secondary carrier of a dual carrier according to an embodiment of the present invention, the method includes the following steps:

Step S102, the scheduler of the base station obtains the amount of data to be sent corresponding to the terminal within a specified time, wherein the terminal is a dual-carrier terminal;

Wherein, the length of the specified time can be set according to experience, for example, the specified time is set as a specified number (500) of scheduling periods, and usually the scheduling period of the scheduler is 2 ms. Based on this, the process for the scheduler to obtain the amount of data can be as follows: the scheduler counts the number of data to be sent in the buffer area corresponding to the terminal within the specified number of scheduling periods; determines the amount of data to be sent corresponding to the terminal according to the number of times The proportion of the entire statistical scheduling cycle.

Preferably, the statistical process of the above-mentioned times is as follows:

The scheduler determines that there are N buffer areas for data to be sent corresponding to the terminal, where N is an integer greater than or equal to 1; the scheduler sets the number of times St for each buffer area, t=1, 2,... ., N; where, the initial value of St is 0; in each scheduling cycle of the specified number of scheduling cycles, the scheduler traverses each buffer area to determine whether each buffer area has data, and if so, the corresponding The number of times St is increased by 1, if not, St remains unchanged.

There are two ways to determine the amount of data. The first way is: when the number of scheduling cycles reaches the specified number T, the base station calculates the non-empty ratio γ _t = St/T corresponding to the terminal, and the maximum of γ _t Value as a non-empty ratio of the number of times the amount of data to be sent corresponds to the terminal.

The second method is: when the number of scheduling cycles reaches the specified number T, the scheduler calculates the non-duty ratio γ _t =St/T corresponding to the terminal, and performs smoothing processing on γ _t , and the smoothed non-duty ratio γ _p = (1-α)·γ _p +α·γ _t , where the value of α is 0.1, the initial value of γ _p is 1, and the maximum value of γ _p is used as the non-parametric value of the number of data to be sent corresponding to the terminal Empty ratio.

For the case of N=1, the number of values of γ _t or γ _p mentioned above will be 1, and at this time, the maximum value of γ _t or γ _p is γ _t or γ _p itself.

Step S104, the scheduler determines a control method for the secondary carrier of the terminal according to the amount of data, wherein the control method includes: activating the secondary carrier and deactivating the secondary carrier;

If the amount of data is less than the first set value and the secondary carrier of the terminal is activated, the scheduler determines that the control mode of the secondary carrier of the terminal is to deactivate the secondary carrier;

If the amount of data is greater than or equal to the second set value, and the secondary carrier of the terminal is in a deactivated state, the scheduler determines that the control mode of the secondary carrier of the terminal is to activate the secondary carrier;

If the amount of data is greater than the first set value and less than the second set value, the scheduler determines that the control mode of the secondary carrier of the terminal is that the secondary carrier remains unchanged;

Wherein, the first set value is smaller than the second set value. The size of the first set value and the second set value can be set according to experience.

Step S106, the scheduler controls the secondary carrier according to the determined control mode.

The specific control is as follows: when the control mode is to deactivate the secondary carrier, the scheduler sends a deactivation secondary carrier command to the terminal through the high-speed shared control channel. Stop the auxiliary carrier to receive data; when the control mode is to activate the auxiliary carrier, the scheduler sends an activation auxiliary carrier command to the terminal through the high-speed shared control channel. After receiving the activation auxiliary carrier command, the terminal starts the auxiliary carrier to receive data after the second specified TTI. Wherein, the number of the first designated TTI and the second designated TTI may be the same, for example, both are 4 TTIs.

The above commands can be implemented through HSSCCH order.

In this embodiment, by counting the amount of data of the terminal within a specified time, and starting the control command of the secondary carrier according to the statistical result, the related technology solves the problem of additional network control overhead caused by frequent sending of HS-SCCHorder and affects system performance. At the same time, by controlling the auxiliary carrier of the terminal, wireless resources and battery power consumption of the terminal are saved.

Example 2

This embodiment provides a method for controlling a secondary carrier of a dual carrier. The method can be implemented through the following modules. These modules can be set on the base station. The specific modules involved are as follows:

1) The scheduling module of the HSDPA scheduler;

2) HSDPCCH demodulation module of HSDPA scheduler;

3) The algorithm module of the HSDPA scheduler;

The scheduling module of the scheduler will first judge whether the HSSCCH order period for sending DC secondary carrier activation/deactivation has arrived at the time of 2ms scheduling. Activate the secondary carrier; if the conditions for sending the HSSCCH order to deactivate the secondary carrier are met, the scheduling module of the scheduler will send the HSSCCH order to the UE to notify the UE to deactivate the corresponding secondary carrier to receive data.

After receiving the above command, the UE will feed back to the scheduler whether it has received the HSSCCHorder command, and stop receiving data on the secondary carrier at a corresponding time.

When the HSDPCCH demodulation module of the scheduler receives the feedback information from the UE, if the UE responds with positive feedback information, the scheduler will stop the data transmission of the secondary carrier; if the UE responds with negative feedback information, it indicates that the UE side is not correct. After receiving the HSSCCH Order, the scheduler will resend the HSSCCH order command in the next Transmission Time Interval (TTI for short). Correspondingly activating the secondary serving cell of the UE is also a corresponding processing flow.

Referring to Figure 2, the method for controlling the secondary carrier of the dual carrier mainly includes the following steps:

In step S202, the scheduler sets a variable St for each queue of the UE to record the number of times the queue has data.

Step S204, every 2ms scheduling period, judge whether there is data in each queue of the UE, if there is no data, execute step S206; if there is data, execute step S208; repeat step S204 until all queues complete the calculation of St; statistics St is completed After that, step S210 is executed;

Step S206, the value of St remains unchanged, that is, St=St;

Step S208, there is data in the current queue, St=St+1;

Step S210, the scheduler judges whether the number of scheduling cycles has reached T times, if yes, execute step S212, if not, there is no need to generate an HS-SCCH order for secondary carrier activation and deactivation for the UE, and the next scheduling cycle arrives After that, return to step S204;

Step S212, calculating the UE statistics MaxRp, and setting St to 0;

Step S214, judging whether MaxRp<k _l is satisfied, and the UE secondary carrier is activated, if yes, execute step S216; if no, execute step S218;

Step S216, sending an order to deactivate the UE secondary carrier, for example, sending an HS-SCCH order for deactivating the secondary carrier;

Step S218, judging whether MaxRp>kp is satisfied, and the UE secondary carrier is deactivated, if yes, execute step S220; if no, return to step S204;

Step S220, sending an order to activate the UE secondary carrier, for example, sending an HS-SCCH order for activating the secondary carrier;

After step S216 and step S220, step S222 is executed to end the current control cycle and enter the next control cycle, that is, T scheduling cycles.

In actual implementation, there will be multiple cells under the scheduler. At this time, it is necessary to traverse all the cells under the scheduler, and find the number of times St that each DPA UE in each cell has data cached in Que in period T, and obtain the UE's The non-empty ratio of each priority queue γ _t = S _t /T, the non-empty ratio after smoothing γ _p = (1-α)·γ _p +α·γ _t (α is 0.1), the initial value of γ _p The value is 1, St is reset to 0, and the maximum value Maxγ _p of the duty cycle after smoothing is taken;

When Maxγ _p is less than k _l and the secondary carrier of the UE is activated, it means that the amount of data of the UE is relatively small in a period of time. At this time, the secondary carrier can be deactivated, and the scheduler needs to generate HS-SCCH order, otherwise go to step G;

When Maxγ _p is greater than or equal to k _h , and the UE secondary carrier is inactive, it means that the data volume of the UE is relatively large in period T, and the secondary carrier can be activated by sending an order command, and the scheduler needs to generate HS-SCCH order, otherwise go to step H;

When Maxγ _p does not satisfy the above conditions, the secondary carrier remains in its original state, and the scheduler will not generate an HS-SCCH order for activating or deactivating the secondary carrier.

According to the above judgment, a command to activate or deactivate the secondary carrier is sent, and the UE is notified to perform corresponding processing. When the UE receives the HSSCCH order and can correctly solve it, the UE will generate positive feedback information to the scheduler, and stop or start the data reception of the secondary carrier at a certain moment; when the UE cannot correctly solve the HSSCCH order, it will Negative feedback information is generated to the scheduler, and the UE does not perform any processing at this time.

After the scheduler sends the HSSCCH order, it will receive feedback information from the UE in 6 TTIs. If the base station finds out that the UE responded with positive feedback information, the scheduler will stop the scheduling of the secondary carrier at the same time and deactivate the secondary carrier of the UE; if the base station finds out that the UE responded with negative feedback information, the scheduler will retransmit the HSSCCH order command, the maximum number of retransmissions is 3, and the scheduler will discard the package after more than 3 times.

At this point, a complete processing flow is completed.

Relevant parameter values: T takes 500, or even longer;

k _l =15%, _kh =60% (both k _l and _kh are set low, which can make it easier for the UE to be in a dual-carrier activation state, thereby ensuring a higher rate for the UE).

In the following, the scheduling of a dual-carrier UE in a cell will be described: set parameters T=500, k _l =15%, _kh =60%;

Step 1: Since the scheduling period of the scheduler is 2ms, record the number of times St that there is data in the dual-carrier UE Que buffer area every 2ms, that is, St=St+1;

Step 2: Determine whether the T period has arrived every 2ms. If the T period has arrived, enter the function DPAALGO_SecondCellActiveOrNot at this time to determine whether the dual-carrier UE meets the conditions for sending HSSCCH order to activate and deactivate the secondary carrier;

Specific operation: traverse all the cells under the scheduler, and find the number of times St that each dual-carrier UE has data buffered in the Que in the cycle T under each cell, and obtain the non-empty ratio of each priority queue of the UE γ _t = S _t /T, the non-empty ratio after smoothing γ _p = (1-α) γ _p + α γ _t (α is 0.1), the initial value of γ _p is 1, St is reset to 0, and smoothing The maximum value of the subsequent duty cycle Maxγ _p ;

Step 3: When Maxγ _p is less than k _l and the secondary carrier of the dual-carrier UE is activated, it means that the data volume of the dual-carrier UE is relatively small within a period of time. At this time, the secondary carrier can be deactivated, and the scheduler Need to generate HS-SCCHorder for deactivating the secondary carrier;

Step 4: When Maxγ _p is greater than or equal to k _h , and the secondary carrier of the dual-carrier UE is inactive, it means that the data volume of the dual-carrier UE is relatively large in period T, and the secondary carrier can be activated by sending an order command, and the scheduling The device needs to generate the HS-SCCH order for activating the secondary carrier;

Step 5: When Maxγ _p and λ do not meet the conditions, the secondary carrier remains in its original state, and the scheduler will not generate an HS-SCCH order for activating or deactivating the secondary carrier;

Step 6: According to the above judgment, send an order command to activate or deactivate the secondary carrier, and notify the dual-carrier UE to perform corresponding processing. When the dual-carrier UE receives the HSSCCH order and can correctly solve it, the dual-carrier UE will generate positive feedback information to the base station, and stop or start the data reception of the secondary carrier after 4 TTIs; when the UE cannot correctly solve the HSSCCH order, At this time, negative feedback information will be generated to the base station, and the dual-carrier UE does not perform any processing at this time.

Step 7: After the scheduler sends the HSSCCH order, it will receive feedback information from the UE in 6 TTIs. If the base station finds out that the dual-carrier UE responds with positive feedback information, the scheduler will stop the scheduling of the secondary carrier at the same time, and deactivate the secondary carrier of the dual-carrier UE; The HSSCCH order command will be retransmitted, and the maximum number of retransmissions is 3. After more than 3 times, the scheduler will discard the command packet.

Step 8: After the hold period of 1s is over, return to the first step and start to execute repeatedly.

By adopting the method of this embodiment, the secondary carrier scheduling of dual-carrier UE can be activated and deactivated through HSSCCH order, and the progress of the application of CPC technology in the DC-HSDPA of the third generation mobile communication system has been achieved. The base station can adopt Dual-carrier or single-carrier data transmission can save the downlink transmission power of the base station and the battery power consumption of the UE, and improve the performance of the HSPA system.

A data amount acquisition module 32, configured to acquire the amount of data to be sent corresponding to the terminal within a specified time, wherein the terminal is a dual-carrier terminal;

The control method determination module 34 is connected to the data amount acquisition module 32, and is used to determine the control method for the auxiliary carrier of the terminal according to the data amount obtained by the data amount acquisition module 32, wherein the control method includes: activating the auxiliary carrier and deactivating the auxiliary carrier ;

Wherein, the length of the specified time can be set according to experience, for example, the specified time is set to a specified number (500) of scheduling cycles, and usually the scheduling cycle of the base station is 2 ms. Based on this, the data amount acquisition module 32 includes: a counting unit for counting the number of times of data to be sent in the buffer area corresponding to the terminal in the scheduling period of the specified number; a determining unit for determining the number of times according to the number of times counted by the counting unit The proportion of the amount of data to be sent corresponding to the terminal to the entire statistical scheduling period.

Preferably, the times counting unit includes: a setting subunit for determining that there are N buffer areas corresponding to the terminal to send data, where N is an integer greater than or equal to 1; and setting the number of times St for each buffer area, t=1, 2,..., N; wherein, the initial value of St is 0; the counting subunit is used to traverse each buffer area in each scheduling cycle of the specified number of scheduling cycles, Determine whether each buffer has data, if yes, add 1 to the corresponding number of times St, if not, St remains unchanged.

The determining unit in this embodiment can be implemented in the following two ways:

Mode 1: The determination unit includes: a first calculation subunit, used to calculate the non-duty ratio γ _t =St/T corresponding to the terminal when the number of scheduling periods reaches the specified number T; the first determination subunit uses It is based on taking the maximum value in γ _t as the non-empty ratio of the amount of data to be sent corresponding to the terminal.

Mode 2: The determination unit includes: a second calculation subunit, used for calculating the non-empty ratio γ _t =St/T corresponding to the terminal when the number of scheduling cycles reaches the specified number T; the smoothing processing subunit is used to After smoothing γ _t , the non-empty ratio γ _p = (1-α)·γ _p +α·γ _t after smoothing, where α is 0.1 and the initial value of γ _p is 1; the second determination A subunit, configured to use the maximum value in γ _p as a non-empty ratio of the amount of data to be sent corresponding to the terminal.

Based on the amount of data obtained above, the control mode determination module 34 includes:

After receiving the command to deactivate the secondary carrier, the terminal stops receiving data on the secondary carrier after the first specified TTI; when the control mode is to activate the secondary carrier, the control module 36 sends the command to activate the secondary carrier to the terminal through the high-speed signaling control channel. After receiving the command to activate the secondary carrier, the terminal starts the secondary carrier to receive data after the second specified TTI. Wherein, the number of the first designated TTI and the second designated TTI may be the same, for example, both are 4 TTIs.
