Description

[0002] With the development of communication technology, in order to improve user perception and increase download and upload rates, multi-cell joint transmission technology, namely carrier aggregation technology, has been introduced. For example, 2.1GHz 40MHz and 3.5GHz 100MHz cross-band carrier aggregation is used for transmission. At this time, the terminal jointly receives and sends data in the cells of carriers in two different frequency bands, thereby greatly improving the user rate.

[0003] However, when uplink carrier aggregation occurs, when the UE (User Equipment) transmits on two carriers, the power transmitted by the carriers of the two cells cannot exceed the maximum transmit power of the UE. Therefore, when the UE moves to the middle point, the PRB (Physical Resource Block) resources allocated in each cell may be small due to power limitation, resulting in a decrease in the transmission rate.

[0036] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0037] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0038] In the embodiments of the present application, the terms "first", "second", etc. are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0039] In order to facilitate understanding of the embodiments of the present application, the following first introduces technologies related to the embodiments of the present application:

[0040] After uplink carrier aggregation is activated, it is necessary to ensure that the total scheduling power of the primary cell and the secondary cell does not exceed the maximum transmit power of the UE. The current strategy is mainly to determine the maximum PRB number of uplink scheduling of the primary cell and the secondary cell based on the uplink BO (Buffer Occupy) allocation ratio.

[0041] Assuming that the uplink BO allocation ratio of the primary cell is ρ1, the uplink BO allocation ratio of the secondary cell is ρ2, and ρ1+ρ2=1 is satisfied, the formula for determining the maximum number of PRBs for uplink scheduling of the primary cell and the secondary cell is as follows:

[0042] Maximum number of PRBs for uplink scheduling in the primary cell = maximum number of PRBs calculated from the primary cell PHR * 10^((UE maximum power - primary cell maximum power + 10log(ρ1)) / 10);

[0043] Maximum number of PRBs for uplink scheduling in the secondary cell = maximum number of PRBs calculated from the secondary cell PHR * 10^((UE maximum power - secondary cell maximum power + 10log(ρ2)) / 10);

[0044] Among them, the maximum power of the primary cell is the maximum power allowed for the UE to transmit in the primary cell, and the maximum power of the secondary cell is the maximum power allowed for the UE to transmit in the secondary cell. When the transmit power of the PUSCH (Physical Uplink Shared Channel) reaches the maximum value, the maximum number of PRBs calculated by the primary cell PHR (Power Headroom Report) and the maximum number of PRBs calculated by the secondary cell PHR can be calculated based on the power headroom currently reported by the UE, as follows:

[0045] PRB_MAX_noLimt(j)=floor(MPUSCH(i)·10PH(i) / 10), where floor means rounding down.

[0046] Among them, PRB_MAX_noLimt(j) is the maximum number of PRBs converted from the primary cell PHR or the maximum number of PRBs converted from the secondary cell PHR, j is 0 for the primary cell, j is 1 for the secondary cell, PH(i) is the power headroom value reported by the UE at time i, and MPUSCH(i) is the PRB resource allocated to the UE at time i.

[0047] In the above scheme for allocating the maximum number of PRBs for uplink scheduling of the primary cell and the secondary cell, if the primary cell schedules too many PRBs, the UE will use the power mainly for the primary cell in order to achieve the power spectrum density of a single PRB, so that the secondary cell has no power available, and the received power on the secondary cell is very low, resulting in uplink decoding failure. In addition, the above scheme cannot solve the problem that when the UE moves to the middle point during the current uplink carrier aggregation, the PRB resources allocated in each cell may be small due to power limitation, resulting in a decrease in transmission rate.

[0048] To this end, the present application provides an uplink carrier aggregation resource scheduling method, network equipment and device. The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] Figure 1 This is one of the flow diagrams of an uplink carrier aggregation resource scheduling method provided in an embodiment of the present application, such as Figure 1 As shown, an embodiment of the present application provides an uplink carrier aggregation resource scheduling method, which is applied to a network device, including:

[0050] Step 101, configure the MCS of the primary cell and the maximum number of uplink schedulable PRBs;

[0051] Step 103, configuring the MCS of the secondary cell and the maximum number of uplink schedulable PRBs;

[0052] Step 105, determining a second maximum uplink transmission block size TBS when the primary cell transmits alone according to the configured MCS of the primary cell and the maximum number of uplink schedulable PRBs;

[0053] Step 107: Determine a third maximum uplink transmission block size TBS when the secondary cell transmits independently according to the configured MCS of the secondary cell and the maximum number of uplink schedulable PRBs.

[0054] The method for specifically determining the maximum uplink transmission block size TBS when the primary cell or the secondary cell transmits independently may be implemented by using relevant technologies, for example, it may be:

[0055] In this application, before determining the maximum uplink transmission block size TBS when the primary cell or the secondary cell transmits alone, the MCS and the maximum number of uplink schedulable PRBs of the primary cell and the secondary cell have been configured. In this application, the intermediate coefficient N is calculated by the following formula info (j)

[0056] N info (j) = N RE (j)·R(j)·Q m (j)·υ(j), (Formula 1), where j is 0 for the primary cell and 1 for the secondary cell, that is:

[0057] For the primary cell, the intermediate coefficient is N info (0), the specific calculation method is: N info (0) = N RE (0)·R(0)·Qm (0)·υ(0);

[0058] For the secondary cell, the intermediate coefficient is N info (1), the specific calculation method is: N info (1) = N RE (1)·R(1)·Q m (1)·υ(1);

[0059] In formula 1, N RE (j) is the number of available REs (Resource Element) in the maximum number of PRBs currently configured for uplink scheduling in the primary cell or the secondary cell, and υ(j) is the number of streams currently scheduled in the primary cell or the secondary cell, which can be obtained by the index value I of the MCS(j) configured in the primary cell and the secondary cell respectively. mcs (j) Look up the table in the 3GPP protocol to obtain the modulation mode value Q of each cell m (j) and the target code rate value R(j); in the above formulas and parameters, when j is 0, it indicates the primary cell, and when j is 1, it indicates the secondary cell;

[0060] Then, the intermediate coefficient N calculated by the main cell info (0) value, look up the table in the 3GPP protocol to obtain the second maximum uplink transport block size TBS of the primary cell; the intermediate coefficient N calculated according to the secondary cell info (1) value, look up the table in the 3GPP protocol to obtain the third maximum uplink transport block size TBS of the secondary cell.

[0061] Step 109, determine the cell for uplink resource scheduling based on the second maximum uplink TBS, the third maximum uplink TBS and the first maximum uplink TBS, wherein the first maximum uplink TBS is the maximum uplink TBS during joint transmission of the primary cell and the secondary cell when the above-mentioned MCS and the maximum number of uplink schedulable PRBs are not configured.

[0062] Optionally, a cell corresponding to the largest one of the second maximum uplink TBS, the third maximum uplink TBS and the first maximum uplink TBS may be determined as a cell for uplink resource scheduling.

[0063] Optionally, the determination of the first maximum uplink TBS (Transport Block Size) during joint transmission of the primary cell and the secondary cell may be accomplished by any achievable method in the relevant technology, which is not limited here. In order to better illustrate the solution, the following example is used for illustration, but it is not intended to limit the implementation method:

[0064] In one example, the method introduced in the above-mentioned related technology to determine the maximum number of PRBs for uplink scheduling of the main cell and the secondary cell based on the uplink BO allocation ratio can be used to determine the maximum number of PRBs for uplink scheduling of the main cell and the secondary cell in this application, PRB_MAX_noLimt(j), where j is 0 for the main cell and j is 1 for the secondary cell.

[0065] Then, calculate the intermediate coefficient N according to formula (1) info (j):

[0066] N info (j) = N RE (j)·R(j)·Q m (j)·υ(j), where j is 0 for the primary cell and 1 for the secondary cell, that is:

[0067] For the primary cell, the intermediate coefficient is N info (0), specific calculation method: N info (0) = N RE (0)·R(0)·Q m (0)·υ(0);

[0068] For the secondary cell, the intermediate coefficient is N info (1), specific calculation method: N info (1) = N RE (1)·R(1)·Q m (1)·υ(1);

[0069] In formula 1, N RE (j) is the number of REs (Resource Element) available in the current maximum number of PRBs for uplink scheduling PRB_MAX_noLimt(j) determined by the primary cell or the secondary cell based on the uplink BO allocation ratio, υ(j) is the number of streams scheduled by the primary cell or the secondary cell, and the index value I of the current MCS(j) (Modulation and Coding Scheme) of the primary cell or the secondary cell is mcs (j) In 3GPP (3 rd The modulation mode value Q of each cell can be obtained by looking up the table in the Third Generation Partnership Project (3rd Generation Partnership Project) protocol. m (j) and the target bit rate value R(j).

[0070] According to N info(j) Look up the table in the 3GPP protocol to obtain the transmission block size TBS(j), where j is 0 for the primary cell and j is 1 for the secondary cell. Then, sum the uplink TBS(0) that can be scheduled for the primary cell and the uplink TBS(1) that can be scheduled for the secondary cell to obtain the first maximum uplink TBS when the primary cell and the secondary cell transmit jointly.

[0071] The present application flexibly configures the MCS and the maximum number of uplink schedulable PRBs of the primary cell and the secondary cell, determines the maximum uplink TBS of the primary cell and the secondary cell for separate transmission based on the configured MCS and the maximum number of uplink schedulable PRBs, and further determines the cell with the optimal uplink TBS for uplink scheduling in combination with the maximum uplink TBS when the primary cell and the secondary cell are jointly transmitted, thereby effectively ensuring the user's uplink carrier aggregation transmission rate.

[0072] Figure 2 This is a second flow chart of an uplink carrier aggregation resource scheduling method provided in an embodiment of the present application, such as Figure 2 As shown, an embodiment of the present application provides an uplink carrier aggregation resource scheduling method, which is applied to a network device, including:

[0073] Step 201, when the first MCS of the primary cell is less than the target MCS of the primary cell, estimating the maximum PRB that can be currently scheduled in the primary cell according to the first MCS of the primary cell;

[0074] Among them, the first MCS of the main cell (expressed as Mcs_MaxPrb(0)) is the MCS corresponding to the first number of PRBs (expressed as PRB_MAX(0)) scheduled by the main cell. The first number of PRBs scheduled by the main cell is the number of PRBs used to schedule the maximum bandwidth of the main cell. The target MCS of the main cell is the minimum MCS that keeps the spectrum efficiency loss value of the cell less than the required reduction value of the signal-to-noise ratio SNR (Signal to Noise Ratio) when reducing the MCS of the main cell. The target MCS of the main cell is expressed as MCS target (0), at this time, the air interface capacity is the largest and the single-user throughput is the highest; according to the experimental simulation results, when the MCS corresponding to the number of PRBs scheduled by the primary cell is greater than the target MCS of the primary cell, a larger uplink TBS can be scheduled by reducing the MCS and increasing the number of PRBs. When the MCS corresponding to the number of PRBs scheduled by the primary cell is less than or equal to the target MCS of the primary cell, it is not recommended to further reduce the MCS. At this time, reducing the MCS will have no positive gain in the uplink TBS transmitted by the primary cell alone.

[0075] Optionally, when the first MCS of the primary cell is less than the target MCS of the primary cell, the maximum PRB that can be currently scheduled in the primary cell can be estimated according to the first number of PRBs of the primary cell, the first MCS of the primary cell, and the target MCS of the primary cell. Specifically:

[0076] When the first MCS of the primary cell is less than the target MCS of the primary cell, that is, Mcs_MaxPrb(0) <MCS target In the case of (0),

[0077] Optionally, the maximum PRB that can be scheduled can be estimated by the following formula:

[0078]

[0079] Among them, PRB_temp(j) represents the estimated maximum PRB that can be scheduled currently, MCS target (j) represents the target MCS, Mcs_MaxPrb(j) represents the first MCS, PRB_MAX(j) represents the first number of PRBs, j is 0 for the primary cell, and j is 1 for the secondary cell;

[0080] That is, the maximum PRB that can be scheduled currently estimated by the primary cell is:

[0081]

[0082] Step 203, according to the estimated size relationship between the current maximum PRB that can be scheduled in the main cell and the second number of PRBs in the main cell, configure the MCS and the maximum number of PRBs that can be scheduled uplink of the main cell, wherein the second number of PRBs in the main cell (expressed as PRB_MAX_noLimt(0)) is the number of PRBs used by the PUSCH of the main cell at the maximum transmit power.

[0083] Optionally, the MCS of the primary cell and the maximum number of uplink schedulable PRBs are configured according to the estimated relationship between the current maximum PRB that can be scheduled in the primary cell and the second number of PRBs in the primary cell, specifically:

[0084] When the estimated maximum PRB that can be currently scheduled in the primary cell is less than the second number of PRBs in the primary cell, configure the MCS of the primary cell to be the second MCS of the primary cell and the maximum number of PRBs that can be scheduled in the uplink to be the second number of PRBs in the primary cell; and / or,

[0085] When the estimated maximum PRB that can be currently scheduled in the main cell is greater than or equal to the second number of PRBs in the main cell, the MCS of the main cell is configured as the target MCS of the main cell, and the maximum number of uplink PRBs that can be scheduled is the estimated maximum PRB that can currently be scheduled in the main cell, wherein the second MCS of the main cell (expressed as Mcs_NoLimit(0)) is the MCS corresponding to the second number of PRBs of the main cell.

[0086] That is, for the primary cell, if PRB_temp(0) < PRB_MAX_noLimt(0), the MCS of the primary cell is configured as: Mcs_NoLimit(0), and the maximum schedulable PRB number in the uplink is: PRB_MAX_noLimt(0); and / or,

[0087] if PRB_temp(0) ≥ PRB_MAX_noLimt(0), the MCS of the primary cell is configured as: MCS target (0), and the maximum schedulable PRB number in the uplink is: PRB_temp(0);

[0088] The above steps 201 and 203 are Figure 1 alternative implementation manners of step 101 in the embodiment.

[0089] Figure 3 It is the third flow diagram of an uplink carrier aggregation resource scheduling method provided by an embodiment of the present application. As Figure 3 shown, an embodiment of the present application provides an uplink carrier aggregation resource scheduling method, which is applied to a network device and includes:

[0090] Step 301, when the first MCS of the secondary cell is less than the target MCS of the secondary cell, estimate the maximum schedulable PRB of the secondary cell according to the first MCS of the secondary cell;

[0091] Among them, the first MCS of the secondary cell (denoted as Mcs_MaxPrb(1)) is the MCS corresponding to the secondary cell scheduling the first number of PRBs (denoted as PRB_MAX(1)), and the first number of PRBs scheduled by the secondary cell is the number of PRBs used for scheduling the maximum bandwidth of the secondary cell; the target MCS of the secondary cell is the minimum MCS that keeps the loss value of the cell spectral efficiency less than the required reduction value of the signal-to-noise ratio SNR (Signal to Noise Ratio) when reducing the MCS of the secondary cell. The target MCS of the secondary cell is denoted as MCS target (1). At this time, the air interface capability is the largest and the single-user throughput is the highest. It is found from the experimental simulation results that when the MCS corresponding to the number of PRBs scheduled by the secondary cell is greater than the target MCS of the secondary cell, a larger uplink TBS can be scheduled by reducing the MCS and increasing the number of PRBs. When the MCS corresponding to the number of PRBs scheduled by the secondary cell is less than or equal to the target MCS of the secondary cell, it is not recommended to further reduce the MCS. At this time, further reducing the MCS will not result in a positive gain in the uplink TBS of the secondary cell for independent transmission.

[0092] Optionally, when the first MCS of the secondary cell is less than the target MCS of the secondary cell, the maximum schedulable PRB of the secondary cell currently can be estimated according to the first number of PRBs of the secondary cell, the first MCS of the secondary cell, and the target MCS of the secondary cell. Specifically:

[0093] When the first MCS of the secondary cell is less than the target MCS of the secondary cell, that is, Mcs_MaxPrb(1) < MCS target (1) in the case of

[0094] Optionally, based on Formula 2 in the above embodiments, the maximum schedulable PRB of the secondary cell currently can be estimated by the following formula:

[0095]

[0096] Step 303: Configure the MCS of the secondary cell and the maximum number of schedulable uplink PRBs according to the size relationship between the estimated maximum schedulable PRB of the secondary cell currently and the second number of PRBs of the secondary cell. Among them, the second number of PRBs of the secondary cell (expressed as PRB_MAX_noLimt(1)) is the number of PRBs used by the secondary cell PUSCH under the maximum transmit power.

[0097] Optionally, configure the MCS of the secondary cell and the maximum number of schedulable uplink PRBs according to the size relationship between the estimated maximum schedulable PRB of the secondary cell currently and the second number of PRBs of the secondary cell. Specifically:

[0098] When the estimated maximum schedulable PRB of the secondary cell currently is less than the second number of PRBs of the secondary cell, configure the MCS of the secondary cell as the second MCS of the secondary cell, and the maximum number of schedulable uplink PRBs as the second number of PRBs of the secondary cell; and / or,

[0099] When the estimated maximum schedulable PRB of the secondary cell currently is greater than or equal to the second number of PRBs of the secondary cell, configure the MCS of the secondary cell as the target MCS of the secondary cell, and the maximum number of schedulable uplink PRBs as the estimated maximum schedulable PRB of the secondary cell currently. Among them, the second MCS of the secondary cell (expressed as Mcs_NoLimit(1)) is the MCS corresponding to scheduling the second number of PRBs of the secondary cell.

[0100] That is, for the secondary cell, if PRB_temp(1) < PRB_MAX_noLimt(1), then configure the MCS of the secondary cell as: Mcs_NoLimit(1), and the maximum number of schedulable uplink PRBs as: PRB_MAX_noLimt(1); and / or,

[0101] If PRB_temp(1)≥PRB_MAX_noLimt(1), the MCS of the secondary cell is configured as: MCS target (1), the maximum number of PRBs that can be scheduled in the uplink is: PRB_temp(1).

[0102] The above steps 301 and 303 are Figure 1 Optional implementation of step 103 in the embodiment;

[0103] The present application flexibly configures the MCS and the maximum number of uplink schedulable PRBs of the primary cell and the secondary cell, and determines the maximum uplink TBS of the primary cell and the secondary cell for separate transmission based on the configured MCS and the maximum number of uplink schedulable PRBs, and combines the maximum uplink TBS when the primary cell and the secondary cell transmit jointly, further determines the cell with the optimal uplink TBS for uplink scheduling, and effectively guarantees the user's uplink carrier aggregation transmission rate.

[0104] Figure 4 This is a fourth flow chart of an uplink carrier aggregation resource scheduling method provided in an embodiment of the present application, such as Figure 4 As shown, an embodiment of the present application provides an uplink carrier aggregation resource scheduling method, which is applied to a network device, including:

[0105] Step 401, when the first MCS of the primary cell is greater than or equal to the target MCS of the primary cell, configure the MCS of the primary cell to be the first MCS of the primary cell, the maximum number of uplink schedulable PRBs to be the first number of PRBs scheduled by the primary cell, wherein the target MCS of the primary cell (expressed as MCS target (0)) is the minimum MCS that keeps the spectrum efficiency loss value of the primary cell less than the required reduction value of the signal-to-noise ratio SNR when the MCS of the primary cell is reduced. The first MCS of the primary cell is (expressed as Mcs_MaxPrb(0)), the MCS corresponding to the primary cell scheduling the first number of PRBs. The first number of PRBs scheduled by the primary cell (expressed as PRB_MAX(0)) is the number of PRBs used to schedule the maximum bandwidth of the primary cell. Specifically, for the primary cell, when the first MCS is greater than or equal to the target MCS, that is, Mcs_MaxPrb(0)≥MCS target In the case of (0), the MCS of the primary cell is configured as the first MCS: Mcs_MaxPrb(0), and the maximum number of uplink schedulable PRBs is configured as the first number of PRBs: PRB_MAX(0);
