Abstract

A method for allocating resources in a wireless mobile communication is provided. The method includes preconfiguring, by a base station, a priority for each data resource pool set; configuring, by a base station, a data transmission period and resource allocation for the data resource pool set based on the priority of the data resource pool set; and acquiring, by a mobile equipment, a number of data resource pool sets and its corresponding relation with its configured priority in the wireless mobile communication.

First claim

What is claimed is:

1. A method for allocating resources in a wireless mobile communication, comprising:
predefining priorities of a plurality of data resource pool sets by three levels having a first priority, a second priority, and a third priority;
acquiring preset priority configuration information from the plurality of data resource pool sets;
configuring a data transmission period and a resource corresponding to the plurality of data resource pool sets based on the preset priority configuration information of the plurality of data resource pool sets;
receiving resource allocation request information from a mobile equipment; and
sending the data transmission period and the resource corresponding to the data resource pool sets satisfying the resource allocation request information to the mobile equipment;
wherein the step of configuring the data transmission period and the resource corresponding to the plurality of data resource pool sets based on the preset priority configuration information of the plurality of data resource pool sets comprises steps of:
(B1) acquiring and determining a priority of one of the data resource pool sets by a base station;
(B2) if the priority of the one of the data resource pool sets is the first priority, adopting a Semi-persistent scheduling indicator (SPSI) resource allocation method for the one of the data resource pool sets and acquiring the resource use with regard to the next data transmission period at the beginning of a first data transmission period;
(B3) if the priority of the one of the data resource pool sets is the second priority, adopting a plan-based resource allocation method for the one of the data resource pool sets and utilizing the plan-based resource allocation method to allocating a second data transmission period at the beginning of the second data transmission period; and
(B4) if the priority of the one of the data resource pool sets is the third priority, adopting a contention-based resource allocation method for the one of the data resource pool sets and utilizing the contention-based resource allocation method to allocating a third data transmission period at the beginning of the third data transmission period.

2. The method of claim 1 , wherein in step (B2), the SPSI comprises a self-resource indicator for indicating its own data or the data of other mobile equipment is transmitting and a data transmission indicator for indicating the duration of data transmission.

3. The method of claim 2 , wherein in step (B4), the contention-based resource allocation method comprises a data handshake method, the data handshake method comprising:
(B41) sending, by the mobile equipment, its own equipment ID, a repeater ID and the desired resource allocation request information to the base station;
(B42) determining, by the base station, whether the repeater accepts the resource allocation of the resource allocation request information, and if the repeater totally accepts the resource allocation, retaining the resource allocation, and if the repeater doesn't accept the resource allocation and provides new resources to the mobile equipment, assigning new resource allocation while confirming the resources; and
(B43) receiving, by the mobile equipment, resource confirmation information from the repeater and transmitting a data based on the agreed resource allocation of the resource confirmation information during the transmission of the data.

4. A method for allocating resources in a wireless mobile communication, comprising:
(A) preconfiguring, by a base station, a priority for each data resource pool set;
(B) configuring, by a base station, a data transmission period and resource allocation for the data resource pool set based on the priority of the data resource pool set; and
(C) acquiring, by a mobile equipment, a number of data resource pool sets and its corresponding relation with its configured priority in the wireless mobile communication;
wherein step (A) comprises a step of predefining priorities of a plurality of data resource pool sets by three levels having a first priority, a second priority, and a third priority; and
wherein step (B) comprises steps of:
(B1) acquiring and determining a priority of one of the data resource pool sets by a base station;
(B2) if the priority of the one of the data resource pool sets is the first priority, adopting a Semi-persistent scheduling indicator (SPSI) resource allocation method for the one of the data resource pool sets and acquiring the resource use with regard to the next data transmission period at the beginning of a first data transmission period;
(B3) if the priority of the one of the data resource pool sets is the second priority, adopting a plan-based resource allocation method for the one of the data resource pool sets and utilizing the plan-based resource allocation method to allocating a second data transmission period at the beginning of the second data transmission period; and
(B4) if the priority of the one of the data resource pool sets is the third priority, adopting a contention-based resource allocation method for the one of the data resource pool sets and utilizing the contention-based resource allocation method to allocating a third data transmission period at the beginning of the third data transmission period.

5. The method of claim 4 , wherein in step (B2), the SPSI comprises a self-resource indicator for indicating its own data or the data of other mobile equipment is transmitting and a data transmission indicator for indicating the duration of data transmission.

6. The method of claim 5 , wherein in step (B4), the contention-based resource allocation method comprises a data handshake method, the data handshake method comprising:
(B41) sending, by the mobile equipment, its own equipment ID, a repeater ID and the desired resource allocation request information to the base station;
(B42) determining, by the base station, whether the repeater accepts the resource allocation of the resource allocation request information, and if the repeater totally accepts the resource allocation, retaining the resource allocation, and if the repeater doesn't accept the resource allocation and provides new resources to the mobile equipment, assigning new resource allocation while confirming the resources; and
(B43) receiving, by the mobile equipment, resource confirmation information from the repeater and transmitting a data based on the agreed resource allocation of the resource confirmation information during the transmission of the data.

7. A system for allocating resources in a wireless mobile communication, comprising:
one or more processors;
a memory; and
one or more applications stored in the memory and configured to be executed by the processors, wherein the one or more applications comprises the operating instructions for performing steps of:
predefining priorities of a plurality of data resource pool sets by three levels having a first priority, a second priority, and a third priority;
acquiring preset priority configuration information from the plurality of data resource pool sets;
configuring a data transmission period and a resource corresponding to the plurality of data resource pool sets based on the preset priority configuration information of the plurality of data resource pool sets;
receiving resource allocation request information from a mobile equipment; and
sending the data transmission period and the resource corresponding to the data resource pool sets satisfying the resource allocation request information to the mobile equipment;

wherein in the step of configuring the data transmission period and the resource corresponding to the plurality of data resource pool sets based on the preset priority configuration information
