Abstract
The present invention relates to a method and apparatus for processing reverse transmission resources of a user terminal in a mobile communication system. When receiving a plurality of grants, the method and apparatus sum resources allocated by the grants, distribute the summed resources to logical channels, map the resources distributed by the logical channels and the logical channels to MAC PDUs according to the data sizes of the MAC PDUs, and allocate the resources distributed by the mapped logical channels.
Claims16
A method performed by a terminal in a wireless communication system, the method comprising:
- receiving, from a base station, a plurality of grants for transmitting multiple medium access control (MAC) packet data units (PDUs) in one transmission time interval (TTI);
- aggregating resources indicated in the plurality of grants;
- allocating the aggregated resources to logical channels in a priority order based on values associated with each resource amount to be allocated preferentially to each of the logical channels;
- in case that any resources remain, allocating the remaining resources to at least one of the logical channels regardless of the values;
- and
- generating the multiple MAC PDUs based on resources that are allocated to each of the logical channels.
A method performed by a base station in a wireless communication system, the method comprising:
- transmitting, to a terminal, a plurality of grants for receiving multiple medium access control (MAC) packet data units (PDUs) in one transmission time interval (TTI);
- and
- receiving, from the terminal, data determined based on the multiple MAC PDUs in the one TTI, the multiple MAC PDUs being generated based on resources that are allocated to each of a plurality of logical channels,
- wherein the resources indicated in the plurality of grants are aggregated and the aggregated resources are allocated to the logical channels in a priority order based on values associated with each resource amount to be allocated preferentially to each of the logical channels, and
- wherein, in case that any resources remain, the remaining resources are allocated to at least one of the logical channels regardless of the values.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- a controller coupled with the transceiver and configured to:
- receive, from a base station, a plurality of grants for transmitting multiple medium access control (MAC) packet data units (PDUs) in one transmission time interval (TTI),
- aggregate resources indicated in the plurality of grants,
- allocate the aggregated resources to logical channels in a priority order based on values associated with each resource amount to be allocated preferentially to each of the logical channels,
- in case that any resources remain, allocate the remaining resources to at least one of the logical channels regardless of the values, and
- generate the multiple MAC PDUs based on resources that are allocated to each of the logical channels.
