Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for resource allocation.
Background
In a wireless communication system, a scheduling algorithm of an MAC layer plays a crucial role, and a good scheduling algorithm can ensure fairness among terminal users, reduce system complexity and improve system throughput.
At present, scheduling algorithms of a wireless communication system are generally divided into an uplink scheduling algorithm and a downlink scheduling algorithm. Allocating uplink resources to position users by an uplink scheduling algorithm, and maintaining an uplink resource pool; and the downlink scheduling algorithm only allocates downlink resources for the users and maintains a downlink resource pool.
Generally, if a certain user has traffic generation in the uplink (or downlink) direction, the uplink (or downlink) scheduling algorithm allocates uplink (or downlink) resources of a certain frequency band to the user; if the user has a downlink (or uplink) traffic arriving at the user later, the downlink (or uplink) scheduling algorithm allocates the downlink (or uplink) resource of another frequency band to the user. If the two bands are not the same band, it is desirable that the end user can operate in two or more bands simultaneously, thereby increasing the complexity of the terminal design and implementation. Thus, end users are specified to operate on only one frequency band.
However, if all end users can only work on one frequency band, there is a problem that when some end user has uplink (or downlink) traffic arriving, the scheduling algorithm allocates the uplink (or downlink) direction resource of the frequency band M to the end user for use, and at the same time, the downlink (or uplink) resource of the frequency band M is reserved for the downlink (or uplink) direction traffic of the end user and is not allocated to other end users for use. Thus, if the end user only has uplink or downlink traffic, the other direction of the frequency band M still cannot be allocated to other end users for use, resulting in idle and wasted resources in the other direction of the frequency band M.
In view of this, the present invention provides a resource allocation method, which can allocate uplink resources and downlink resources of the same sub-band to different terminal users, thereby avoiding the idle of resources in a certain direction in the sub-band and effectively improving the utilization rate of the sub-band.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
When allocating resources to users in a wireless communication system, the current scheduling algorithm of the MAC layer allocates resources in both uplink and downlink directions of the same sub-band to the same user, that is, for one sub-band, the uplink resources and the downlink resources are allocated in a bundled manner, so that when a user only needs resources in one direction of the sub-band, resources in the other direction are idle and wasted.
To address this problem, the present invention provides a method for resource allocation, and fig. 1 is a schematic diagram of the method in an embodiment of the present invention.
The method divides a user queue waiting for resource allocation into a first class user queue and a second class user queue according to the priority from high to low, wherein the first class user is a user with service transmission in one direction and service arrival in the other direction, and the second class user is all users with service arrival, and the method comprises the following steps of periodic execution:
a. when the current scheduling allocation cycle begins, sequentially taking out the first class users waiting for resource allocation from the queue of the first class users, and allocating resources in the other direction for each first class user waiting for resource allocation;
b. when all the first class users in the queues of the first class users finish the resource allocation process of the current scheduling period, the second class users waiting for resource allocation are sequentially taken out from the queues of the second class users, and resources are allocated to each second class user waiting for resource allocation.
In the method, the first type of users are users whose services are being transmitted in one direction and whose services arrive in the other direction, that is, the first type of users occupy a self-contained resource in one direction, and the resource in the other direction is not bundled with the resource in the occupied direction and allocated to the first type of users, so that the resource in the other direction on the sub-band can be allocated to other users for use before the services arrive in the other direction of the first type of users, thereby reducing the waste caused by the idle sub-band resources.
For the resource allocation of a period, when the current scheduling allocation period starts, first, the first class users waiting for resource allocation are sequentially taken out from the queue of the first class users with high priority, and the taking-out sequence of the first class users can be according to the service arrival sequence of each first class user. And then, allocating resources to the other direction of the taken current first-class users until allocating resources to each first-class user waiting for allocating resources.
In the current scheduling and allocating period, all the first class users in the first class user queue perform the resource allocation process, when the resource pool has idle sub-band resources which can be allocated to the current first class users, the corresponding idle sub-band resources are allocated to the current first class users, so that the first class users end the current scheduling and allocating period, and when the resource pool has no idle sub-band resources which can be allocated to the current first class users, the first class users directly end the current scheduling and allocating period. That is, in one scheduling allocation period, each first class user performs a resource allocation process, and when there is no free user to allocate to the first class user, the resource allocation process of the first class user in the scheduling allocation period is also ended, and the next scheduling allocation period is waited for reallocation.
Therefore, when all the first-class users in the queues of the first-class users finish the resource allocation process of the current scheduling period, the second-class users waiting for resource allocation are sequentially taken out from the queues of the second-class users, and resources are allocated to each second-class user waiting for resource allocation.
Therefore, in one scheduling allocation period, resource allocation is preferentially performed on each first class user, and when the idle subband resources corresponding to the first class users cannot be allocated, the resource allocation process of the first class users in the current scheduling allocation period is ended, and a next scheduling allocation period needs to be waited. And only after all the first-class users finish the resource allocation process in the current period, the resource allocation for the second-class users is started.
Thus, the sub-band resource is preferentially allocated to the first class of users, the first class of users occupying one direction of the sub-band can preferentially select the sub-band, and the resource in the other direction of the same sub-band occupied by the first class of users is allocated to the first class of users.
According to the method, when the resources are allocated to the first class of users and the second class of users, the resources are allocated according to the priority level, and the resources in two directions of the sub-band are not required to be bound and then must be allocated to the same user, so that the sub-band resources can be flexibly allocated to the users waiting for resource allocation, the sub-band resources are prevented from being monopolized by a certain user, the idle resources in the other direction of the sub-band are effectively and fully utilized, and the utilization rate of the sub-band is improved.
For the first class users, the resources allocated to each first class user in two directions belong to the same sub-band. For this purpose, as shown in fig. 2, step a includes the following steps:
a1, reading the attribute list of the current first class user waiting to allocate resource, which is taken out from the queue of the first class user, and obtaining the sub-band information occupied by the current first class user in the transmission service direction;
a2, when the resource corresponding to the current service arrival direction of the current first class user in the occupied sub-band is idle, allocating the sub-band resource corresponding to the current service arrival direction of the current first class user in the sub-band to the current first class user;
a3, when the sub band resource corresponding to the current service arrival direction of the current first class user in the occupied sub band is occupied by other users, the current first class user waits for the next scheduling allocation period.
When entering a scheduling allocation cycle, and allocating resources preferentially to the first type of users, the first type of users need to acquire subband information occupied by the first type of users in the direction of transmitting the service, read the subband attribute list, and further acquire whether the resources of the occupied subbands and the direction required by the direction of arrival of the service of the first type of users are in an idle state. And when the resources corresponding to the current service arrival direction of the current first class user in the acquired occupied sub-band are in an idle state, distributing the resources to the current first class user. And when the resources corresponding to the current service arrival direction of the current first class user in the acquired occupied sub-bands are already allocated to other users in the last scheduling allocation period and are occupied, skipping the allocation of the resources to the first class user so that the first class user waits for the next scheduling allocation period. By adopting the method, the resources of the sub-band are fully used by each user when in an idle state, namely, one sub-band can simultaneously provide resources for two different users, so that the situation that one sub-band only utilizes the resources in one direction and the other direction is always in an idle waiting state is avoided, and the utilization rate of the sub-band is effectively improved.
Referring to fig. 3, in step b, it is further identified whether each second type user in the queue of the second type user has resources in the service arrival direction, and the resource allocation to the second type user having resources in the service arrival direction is skipped.
Specifically, step b includes:
b1, reading the attribute list of the current second user waiting for resource allocation from the second user queue, and obtaining the sub-band resource allocation state of the current service arrival direction of the current second user;
b2, if the sub-band resource has been allocated to the current service reaching direction of the current second type user, skipping the sub-band resource allocation to the current service reaching direction of the current second type user;
b3, if the current service reaching direction of the current second class user is not allocated with sub-band resources, when the resource pool has idle sub-band resources corresponding to the current service reaching direction, allocating the idle sub-band resources to the current second class user, and when the resource pool has no sub-band resources corresponding to the current service reaching direction, the current second class user waits for the next scheduling allocation period.
For the second class of users, it is the user that has traffic arriving in one direction. Therefore, the second type of users may include the first type of users, and also include users that have no service transmission in both directions and have service arrival in one or both directions, and also include users that are transmitting service in the current direction and have service arrival in the current direction, wherein the priority level of the first type of users is higher than that of the other two types of users.
For the users transmitting the service in the current direction and having the service arriving in the current direction, because the service transmission is performed in the current direction, namely the users have already allocated the resource in the current service arriving direction, the resource can be directly continuously used by the current service arriving direction of the users, and the resources are skipped to be allocated to the current service arriving direction of the second type of users in the current scheduling allocation period.
When no sub-band resource is allocated to the current service arrival direction of the current second class user, for example, no service is transmitted in both directions of the current second class user, and when a service arrives in one or both directions, the corresponding idle sub-band resource needs to be allocated to the second class user from the resource pool. And when the resource pool has the idle sub-band resource corresponding to the current service arrival direction, allocating the idle sub-band resource to the current second class user, and when the resource pool has no sub-band resource corresponding to the current service arrival direction, the current second class user also needs to wait for the next scheduling allocation period.
As can be seen from fig. 4, in one scheduling allocation period, the priority level of the first type users is higher than that of the second type users, and a resource allocation process is performed on each first type user in the queue of the first type users, and when the resource allocation of each first type user in the queue of the first type users is successful or the resource allocation fails, the resource allocation process starts to allocate resources to the second type users.
The above method for resource allocation is elaborated, and the invention also provides a corresponding device for resource allocation. Please refer to fig. 5.
The resource allocation device divides a user queue waiting for resource allocation into a first class user queue and a second class user queue according to the priority level from high to low, wherein the first class user is a user with service transmission in one direction and service arrival in the other direction, the second class user is all users with service arrival, and the device comprises the following modules which are operated periodically:
the first allocation module is used for sequentially taking out the first class users waiting for resource allocation from the queue of the first class users when the current scheduling allocation period starts, and allocating the resources in the other direction for each first class user waiting for resource allocation;
and the second distribution module is used for sequentially taking out the second class users waiting for resource distribution from the queues of the second class users and distributing the resources for each second class user waiting for resource distribution when all the first class users in the queues of the first class users finish the resource distribution process of the current scheduling period.
In order to make the resources allocated in both directions for each user of the first type belong to the same subband. The first distribution module comprises:
the first attribute reading submodule reads an attribute list of the current first class user waiting for resource allocation, which is taken out from the queue of the first class user, and acquires sub-band information occupied by the current first class user in the transmission service direction;
the first sub-band module is used for allocating the sub-band resources corresponding to the current service arrival direction of the current first class user in the sub-band to the current first class user when the resources corresponding to the current service arrival direction of the current first class user in the occupied sub-band are idle;
and the first waiting sub-module is used for waiting for the next scheduling and distributing period when the sub-band resource corresponding to the current service arrival direction of the current first class user in the occupied sub-band is occupied by other users.
For the second allocating module, as shown in fig. 5, it further identifies whether each second type user in the queue of the second type user has resources in the traffic arrival direction, and skips resource allocation to the second type users having resources in the traffic arrival direction.
Accordingly, the second allocation module comprises:
the second reading attribute submodule reads an attribute list of the current second type user waiting for resource allocation, which is sequentially taken out from the queue of the second type user, and acquires a sub-band resource allocation state of the current service arrival direction of the current second type user;

and the second allocation sub-module is used for allocating the idle sub-band resource to the current second type user when the idle sub-band resource corresponding to the current service arrival direction exists in the resource pool if the sub-band resource is not allocated in the current service arrival direction of the current second type user, and waiting for the next scheduling allocation period by the current second type user when no sub-band resource corresponding to the current service arrival direction exists in the resource pool.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
