Method of allocating radio resources in a wireless communication system

Abstract

A method of allocating radio resources in a wireless communication system is disclosed. A method of allocating radio resources from a network of a wireless communication system in accordance with a plurality of scheduling modes comprises transmitting first scheduling information to a user equipment to allocate radio resources to the user equipment in accordance with a first scheduling mode, the first scheduling information including a first user equipment identifier, and transmitting second scheduling information to the user equipment to allocate radio resources to the user equipment in accordance with a second scheduling mode, the second scheduling information including a second user equipment identifier.

The invention claimed is: 
     
       1. A method of radio resources allocation at a user equipment of a wireless communication system, the method comprising:
 receiving scheduling information from a network, wherein the scheduling information comprises either a radio network temporary identifier (C-RNTI) to indicate that the scheduling information is associated with a dynamic scheduling mode or a Semi-Persistent Scheduling RNTI (SPS-C-RNTI) to indicate that the scheduling information is associated with a semi-persistent scheduling mode; 
 if the scheduling information comprises the C-RNTI, receiving downlink data using the scheduling information during a corresponding transmission interval only; and 
 if the scheduling information comprises the SPS-C-RNTI, receiving the downlink data using the scheduling information periodically according to an allocation period included in the scheduling information. 
 
     
     
       2. The method of  claim 1 , wherein the C-RNTI and the SPS-C-RNTI are allocated from the network before receiving the scheduling information. 
     
     
       3. The method of  claim 1 , wherein the scheduling information is received on a physical downlink control channel (PDCCH). 
     
     
       4. A method of radio resources allocation at a user equipment of a wireless communication system, the method comprising:
 receiving scheduling information from a network, wherein the scheduling information comprises either a radio network temporary identifier (C-RNTI) to indicate that the scheduling information is associated with a dynamic scheduling mode or a Semi-Persistent Scheduling RNTI (SPS-C-RNTI) to indicate that the scheduling information is associated with a semi-persistent scheduling mode; 
 if the scheduling information comprises the C-RNTI, transmitting uplink data using the scheduling information during a corresponding transmission interval only; and 
 if the scheduling information comprises the SPS-C-RNTI, transmitting the uplink data using the scheduling information periodically according to an allocation period included in the scheduling information. 
 
     
     
       5. The method of  claim 4 , wherein the C-RNTI and the SPS-C-RNTI are allocated from the network before receiving the scheduling information. 
     
     
       6. The method of  claim 4 , wherein the scheduling information is received on a physical downlink control channel (PDCCH). 
     
     
       7. A user equipment for use in a wireless communication system, the user equipment comprising:
 a receiver configured to:
 receive scheduling information from a network, wherein the scheduling information comprises either a radio network temporary identifier (C-RNTI) to indicate that the scheduling information is associated with a dynamic scheduling mode or a Semi-Persistent Scheduling RNTI (SPS-C-RNTI) to indicate that the scheduling information is associated with a semi-persistent scheduling mode; 
 receive downlink data using the scheduling information during a corresponding transmission interval only, if the scheduling information comprises the C-RNTI; and 
 receive the downlink data using the scheduling information periodically according to an allocation period included in the scheduling information, if the scheduling information comprises the SPS-C-RNTI; and 
 
 a transmitter configured to:
 transmit uplink data using the scheduling information during a corresponding transmission interval only, if the scheduling information comprises the C-RNTI; and 
 transmit the uplink data using the scheduling information periodically according to an allocation period included in the scheduling information, if the scheduling information comprises the SPS-C-RNTI.
