Background technique

Long Term Evolution-Advanced (LTE-A) is an evolved version based on the Long Term Evolution (LTE) system. It is introduced to expand to higher bandwidth and peak transmission rate. The carrier aggregation technology essentially expands the bandwidth of a plurality of LTE-based frequency bands by carrier aggregation.

In the LTE-A system to which the carrier aggregation is applied, the carrier that participates in the aggregation is called a component carrier (component carrier), and the user equipment (User Equipment, UE for short) can transmit and receive on the multiple component carriers simultaneously. For a UE (Carrier aggregation UE, CA for short), a component carrier is used as a primary serving cell (PCell), and the primary cell carries signaling and data. The UE also has one or more component carriers as secondary cells (Secondary serving cells, referred to as SCells), and these cells carry data transmission.

In the LTE system, the UE scheduling priority of a certain cell is determined according to the channel quality index (CQI), the historical average transmission rate, and the QoS Class Identifier (QCI) of the UE. .

As described above, since the CA UE can perform data transmission and reception with the eNB by using multiple carriers on the LTE-A system, the scheduling priority of the corresponding CA UE is higher than that of the LTE legacy UE and the non-CA UE, so that the CA UE The obtained carrier resources will be superior to the LTE legacy UE or the non-CA UE. If the corresponding carrier resources are allocated according to the scheduling priority, the QoS of the LTE legacy UE and the non-CA UE will be lower than the CA UE, and then the LTE legacy UE and the non-CA UE. The scheduling priority of the LTE legacy UE and the non-CA UE may be reduced due to the uneven scheduling of the carrier resources due to the scheduling priority.

An effective solution has not been proposed for the problem that the communication quality of the LTE legacy UE and the non-CA UE is degraded due to the uneven scheduling of the carrier resources due to the scheduling priority.

detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

A resource allocation method is provided in this embodiment. FIG. 1 is a flowchart of a resource allocation method according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps:

Step S100: Determine a carrier preference weight of the user equipment UE on the component carrier, where the carrier preference weight is determined according to user attribute information of the UE.

Step S102, determining a priority of the UE on the component carrier according to the determined carrier preference weight.

Step S104, allocating resources to the UE according to the determined priority.

Through the foregoing steps, the priority of the component carrier allocated to the UE is determined by the carrier preference weight of the user on the component carrier, and the resource is allocated to the UE according to the determined priority. The priority of the CA UE is far from the related technology. Compared with other types of UEs, the probability of other UEs scheduling component carriers is low, and the priority of component carriers is determined by means of carrier preference weights, and the probability of debugging resources between CA UEs and other UEs can be adjusted accordingly, effectively In the related art, the debugging of carrier resources is uneven, resulting in a problem of low communication quality, effectively increasing the probability of high resources of other UEs, and improving communication quality to a certain extent.

It should be noted that the foregoing user attribute information may include multiple types, for example, at least one of the following: the number of active component carriers currently configured by the UE, the number of component carriers currently configured by the UE, the resources that the UE is currently scheduled, and the UE's Device type, channel quality indicator (CQI) of the UE, calendar The QoS Class Identifier (QoS Class Identifier, QCI for short), and the device type of the UE, where the device type of the UE includes: carrier aggregation user equipment CA UE (Carrier aggregation), and long-term evolution legacy user equipment LTE Legacy UE or non-carrier aggregation user equipment is not a CA UE. The base station determines the carrier preference weight of the UE on the component carrier according to the device type of the UE, in combination with the number of component carriers used by the UE or the resources currently scheduled by the UE.

In summary, the embodiment provided by the present invention determines the priority of the UE on the component carrier by determining the carrier preference weight of the UE, and allocates the corresponding resource according to the priority of the UE on the component carrier. The priority of the UE on the component carrier is calculated according to the carrier preference weight of the UE on the component carrier and the initial priority of the UE on the component carrier according to the monotonic non-decreasing function. The embodiments provided by the present invention are applicable to the base station acquiring the user attribute information of the CA UE, the LTE legacy UE, or the non-CAR aggregation non-CA UE. When the base station acquires the UEs of the above types, the The user attribute information of each type of UE determines the carrier preference weights corresponding to the respective types of UEs. In determining the carrier preference weights of the UEs on the component carriers, the embodiment of the present invention uses a monotonic non-increment function. Limiting the carrier preference weight of the CA UE, and narrowing the difference between the carrier preference weight of the non-CA UE of the LTE legacy UE or the non-carrier aggregation user equipment and the carrier preference weight of the CA UE, thereby determining the component carrier. At the priority level, the carrier resource allocation average is guaranteed.

Determining the carrier preference weight of the UE on the component carrier may be performed in multiple manners. For example, the carrier preference weight of the UE on the component carrier may be determined by determining the carrier preference of the UE on the component carrier. The value is a monotonous non-increment function value supporting the number of component carriers used by the UE; determining a carrier preference weight of the UE on the component carrier is a monotonic non-incremental function value of the resource that the UE has been scheduled; determining the value according to the monotonic non-increment function and monotonous The value of the monotonic non-decreasing function obtained by the non-incremental function value calculation is the carrier preference weight, which are respectively described below:

Manner 1: Determine the carrier preference weight of the UE on the component carrier as the monotonic non-increment function value of the number of component carriers used by the UE.

The value of the monotonic non-increment function of the number of component carriers used by the UE to determine the carrier preference weight of the UE on the component carrier may be:

If the number of component carriers that the UE can use is N, the carrier preference value of the UE on the component carrier is:

N is the number of component carriers used by the UE;

Or, if the number of component carriers that the UE can use is N, the carrier preference value of the UE on the component carrier is:

Where x is a positive real number.

The number of component carriers supported by the UE includes at least one of the following: an active member currently configured by the UE The number of waves, the number of component carriers currently configured by the UE, and the number of component carriers that the UE is currently expected to be scheduled.

In combination with the above, the carrier preference weight of the UE on the component carrier is calculated by an example:

As shown in FIG. 2, it is assumed that the UE type acquired by the base station in the LTE-A system is a CA UE, an LTE legacy UE, and a non-CA UE that is not configured with an aggregated carrier.

a. It is assumed that the device type of the UE1 is a CA UE, and the number of component carriers that can be used by the CAUE is three. The carrier preference weight of the UE1 on the component carrier is calculated by using the formula (1), and the following is obtained:

UE1: Factor=1/3, N=3;

The carrier preference weight of the upper UE1 on the component carrier is 1/3;

b. It is assumed that the device type of the UE2 is an LTE legacy UE, and the device type of the UE3 is a non-CA UE that is not configured with an aggregated carrier. The number of component carriers that can be used by the LTE legacy UE and the non-CA UE in the LTE-A system is 1, and is used. Equation (1) calculates the carrier preference weights of UE2 and UE3 on the component carrier, and obtains:

UE2: Factor=1/1=1, N=1;

UE3: Factor=1/1=1, N=1;

The carrier preference weight on the component carrier by the upper UE2 is 1; the carrier preference weight of the UE3 on the component carrier is 1.

In summary, the carrier preference weight of the UE1 acquired by the base station on the component carrier is 1/3; the carrier preference weight of the UE2 on the component carrier is 1; and the carrier preference weight of the UE3 on the component carrier is 1. It can be seen that the carrier preference weight of the CA UE on the component carrier is limited by the monotonic non-increment, and the carrier preference weights of the LTE legacy UE and the non-CA UE on the component carrier are larger than the CA UE, which increases the The probability that the LTE legacy UE and the non-CA UE get more carrier resources at the base station.

The above example can also be calculated by the formula (2), and the obtained effect is not described here as described above, wherein x can be determined as a constant according to the actual situation.

Manner 2: determining that the carrier preference weight of the UE on the component carrier is a monotonic non-incremental function value of the resource that the UE has scheduled.

The resource that the UE has been scheduled includes at least one of the following: a resource that is scheduled by the UE in a predetermined time period; where the resource that the UE has been scheduled may be a resource that is scheduled by the UE in the TTI or a certain time period; The total number of times the UE has been scheduled by other component carriers except the component carrier; the total number of codewords that the UE has been scheduled by other component carriers except the component carrier; the total number of bits that the UE has been scheduled by other component carriers except the component carrier.

According to the monotonic non-increment function in the first method, that is, the formula (1) or the formula (2), the second UE has been The scheduled resource is used as a variable in the formula (1) or the formula (2) to calculate the carrier preference weight of each type of UE acquired by the base station on the component carrier.

In the second mode, the carrier preference weight of the UE on the component carrier is related to the determinable resource value. If the UE can be scheduled with more resources, the carrier preference weight of the UE on the component carrier is smaller.

Manner 3: determining a monotonic non-increment function value calculated according to the number of component carriers used by the UE and a monotonic non-increment function value calculated by the UE's scheduled resource, the value of the monotonic non-decreasing function is a carrier preference weight.

Wherein, by at least one of the following formulas, determining a monotonic non-increment function value Factor1 according to the number of component carriers used by the UE and a monotonic non-incrementing function value Factor2 of the resource that the UE has been scheduled, the value of the monotonic non-decreasing function value calculated by Factor2 is a carrier preference. The Factor Factor, where Factor is a monotonic non-decreasing function of the monotonic non-incremental function value Factor1 of the number of component carriers used by the UE, and Factor is a monotonic non-decreasing function of the monotonic non-incremental function value Factor2 of the resource that the UE has scheduled:

Factor=Factor1+Factor2; (3)

Factor=Factor1×Factor2; (4)

Factor=Facotr1 ^Factor2 ; (5)

Factor=Facotr2 ^Factor1 . (6)

As described above, Factor1 is the carrier preference weight of the UE on the component carrier calculated according to the first method, and Factor2 is the carrier preference weight of the UE on the component carrier calculated according to the second method; The carrier preference weight obtained by supporting the number of component carriers used by the UE, and the carrier preference weight of the UE in the third mode calculated by the monotonic non-decreasing function according to the carrier preference weight obtained by the UE according to the resource that the UE has already scheduled in the second mode. The value is such that the carrier preference weight of the UE obtained by the mode 3 is obtained by combining the number of component carriers used by the UE and the resources that the UE has been scheduled, and can further reflect the “preference” of the UE on the component carrier, and enhance the value. The scientific nature of carrier preference weights.

The formulas (1) to (6) provided in the embodiments of the present invention are preferred implementations of a resource allocation method provided by the present invention, and are not specifically limited.

Preferably, in step S102, determining, according to the determined carrier preference weight, a priority of assigning a component carrier to the UE, including:

Step 1: Determine, according to the channel quality indicator, the historical average transmission rate, and the QoS level identifier of the UE, the initial priority Q _{i of the} component carrier allocated to the UE on the component carrier, i is a positive real number; and combine the channel of the UE on the component carrier. Quality indication CQI, historical average transmission rate and quality of service level identification QCI, determining the initial priority Q _{i of the} UE;

Step 2: Determine that the monotonic non-decreasing function value calculated according to the carrier preference weight and the initial priority Q _i is the priority of the component carrier allocated by the UE.

Step 2 calculates the scheduling priority of the UE on the component carrier by using the carrier preference weight of the UE on the component carrier as a factor.

Preferably, the value of the monotonic non-decreasing function obtained by calculating the carrier preference weight Factor and the initial priority Q _i according to at least one of the following formulas is determined, wherein the Q is a priority of the component carrier. a monotonic non-decreasing function of the value Factor;

Q=Q _i ×Factor; (7)

Q=Q _i +Factor. (8)

In summary, the priority of assigning component carriers to the UE is calculated in the manner of the carrier preference weights on the component carriers calculated in any one of the steps S100, and the following processing may be adopted:

In the method of step S100, the obtained component carrier weights obtained by the UE on the component carrier are, that is, UE1:Factor=1/3; UE2:Factor=1; UE3:Factor=1; assume initial priority of UE1 The level Q ₁ is 3, the initial priority Q ₂ of UE2 is 2, and the initial priority Q ₃ of UE3 is 1, and the calculation is performed by taking Equation (7) as an example to obtain Q:

UE1: Q=3×1/3=1;

UE2: Q=2×1=2;

UE3: Q=1×1=1;

As described above, the priorities of UE1, UE2, and UE3 acquired by the base station are: 1, 2, and 1, respectively.

The UE is allocated a corresponding resource according to the priority of the UE on the component carrier determined in step S102, and the resource may be a carrier resource used by the UE.

It can be seen that, in step S100, UE1 is a CA UE, and UE2 is an LTE legacy UE. The priority of UE1 is lower than UE2 in the calculation of the priority of the UE on the component carrier in steps S100 and S102, and the CA UE in the related art. The priority of the LTE legacy UE is different. The resource allocation method provided by the embodiment of the present invention enables the UEs of the LTE legacy UE and the non-CA UE to have a priority greater than or equal to the CA UE, thereby allocating carrier resources to the UE of the type UE in step S104. The average allocation of carrier resources is ensured, and the communication quality between the LTE legacy UE and the non-CA UE is improved.
