Patent ID: 8089988

Claim:
A method for allocating resources to transmit data from an upper layer to a lower layer in a mobile communication system, the method comprising: configuring by a radio resource control (RRC) layer a first amount of data to be transmitted for each logical channel; allocating resources by a medium access control (MAC) layer, wherein the resources are allocated for each logical channel according to the first amount of data to be transmitted for each logical channel, wherein a resource allocation is respectively guaranteed for all logical channels having data to be transmitted such that at least the respective first amount of data to be transmitted for all logical channels is transmitted; and allocating any remaining resources by the MAC layer, wherein the any remaining resources are allocated for each logical channel in order of priority of the logical channels according to a second amount of data to be transmitted for each logical channel; wherein the first amount of data to be transmitted for each logical channel is associated with a quality of service (QoS), wherein the resources are related to at least one of a transport block (TB), a transport format combination (TFC), or a transport format combination set (TFCS), wherein allocating resources for each logical channel with respect to the first amount of data to be transmitted for each logical channel is performed in order of priority of the logical channels.
