DYNAMIC RESOURCE ALLOCATION METHOD
First Claim
1. A dynamic resource allocation method, adapted to a base station for allocating resources to at least one machine-type communication device within a communication group at a random access slot, the method comprising:
- estimating a number of contending devices in the random access slot;
calculating a reference value according to the number of the contending devices and a resource allocation parameter;
calculating a number of specific resources according to the number of the contending devices, a number of acknowledgeable machine-type communication devices of the base station at the random access slot and a preamble detection probability, wherein the specific resources are the resources required to detect the number of machine-type communication devices that is less than or equal to a number of acknowledgeable machine-type communication devices of the base station at the random access slot;
determining a number of reserved random access opportunities according to a maximum number of the random access opportunities, the number of the specific resources and the reference value; and
allocating the resources to the at least one machine-type communication device according to the number of the reserved random access opportunities.

Abstract
A dynamic resource allocation method is introduced herein. The method is adapted to a base station. The method includes the following steps. A number of contending devices in the random access slot is estimated. A reference value is calculated according to the number of the contending devices and a resource allocation parameter. A number of specific resources is calculated according to the number of the contending devices, a number of acknowledgeable machine-type communication devices of the base station at the random access slot and a preamble detection probability. A number of reserved random access opportunities is determined according to a maximum number of the random access opportunities, the number of the specific resources and the reference value. The resources are allocated to the at least one machine-type communication device according to the number of the reserved random access opportunities.

7. A dynamic resource allocation method, adapted to a base station for allocating resources to at least one machine-type communication device within a communication group, the method comprising:
-
obtaining a resource allocation parameter by performing an optimization operation to an access success probability of the communication group to which the at least one machine-type communication device belongs; and sending a paging message to the at least one machine-type communication device within the communication group, wherein the paging message at least comprises the resource allocation parameter, a number of acknowledgeable machine-type communication device of the base station, a maximum number of random access opportunities in an random access slot and a total number of the at least one machine-type communication device comprised in the communication group. - View Dependent Claims (8)
