System and method for physical shared channel allocation in a wireless communication system
View Patent ↗A system and method for physical shared channel allocation in a UMTS wireless communication system. A physical shared channel allocation message ( 220 ) is sent containing a plurality of occurrences of allocated physical resources and TFCS IDs; and, at a radio unit ( 130 A), the sent physical shared channel allocation message is received and the plurality of occurrences of allocated physical resources and TFCS IDs contained therein are processed, thereby allowing a plurality of CCTrCHs to be allocated with a single physical shared channel allocation message ( 220 ). This provides the advantage that, using only a limited set of defined transport format combinations, a large portion of the physical resource can be allocated and used by a single UE using a single physical shared channel allocation message.

means at the radio unit for receiving the sent physical shared channel allocation message, and for processing the plurality of sets of indicators for allocated physical resources and the associated transport format identifications contained therein, thereby allowing a plurality of composite transport channels to be allocated with a single physical shared channel allocation message.
2. The wireless communication system as claimed in claim 1 wherein the number of composite transport channels allocated by the physical shared channel allocation message is equal to the maximum allowed number of composite transport channels allowed in the system.
3. The wireless communication system as claimed in claim 1 wherein the system is a Universal Mobile Telecommunications System (UMTS) system, each set of transport format identifications form a transport format combination set, and the composite transport channels are coded composite transport channels.
4. A method for physical shared channel allocation in a wireless communication system to allocate shared physical channel resources to a radio unit, the method comprising:
sending a physical shared channel allocation message containing a plurality of sets of indicators for allocated physical resources and an associated set of transport format identifications for each of the sets of indicators for allocated physical resources, wherein the physical shared channel allocation message relates to Time Division Duplex (TDD) mode, and the physical shared channel allocation message indicates a plurality of composite transport channels to be allocated to the receiving radio based upon processing of the physical shared channel allocation message by the receiving radio.
5. The method for physical shared channel allocation as claimed in claim 4 wherein the number of composite transport channels allocated by the physical shared channel allocation message is equal to the maximum allowed number of composite transport channels allowed in the system.
6. The method for physical shared channel allocation as claimed in claim 4 wherein the system is a Universal Mobile Telecommunications System (UMTS) system, each set of transport format identifications form a transport format combination set, and the composite transport channels are coded composite transport channels.
7. A wireless communication system using physical shared channel allocation messaging for allocation of a shared physical channel, the wireless communication system unit comprising:
means for sending a physical shared channel allocation message containing a plurality of sets of indicators for allocated physical resources and an associated set of transport format identifications for each of the sets of indicators for allocated physical resources, wherein the physical shared channel allocation message relates to Time Division Duplex (TDD) mode, and the physical shared channel allocation message indicates a plurality of composite transport channels to be allocated to the receiving radio based upon urocessing of the physical shared channel allocation message by the receiving radio.
8. The wireless communication system as claimed in claim 7 , wherein the number of composite transport channels allocated by the physical shared channel allocation message is equal to the maximum allowed number of composite transport channels allowed in the system.
9. The wireless communication system as claimed in claim 7 wherein the system is a Universal Mobile Telecommunications System (UMTS) system, each set of transport format identifications form a transport format combination set, and the composite transport channels are coded composite transport channels.
10. A radio unit for use in a wireless communication system employing physical shared channel allocation messaging for allocation to a shared physical channel, the radio unit comprising:
means for receiving a physical shared channel allocation message containing a plurality of sets of indicators for allocated physical resources and an associated set of transport format identifications for each of the sets of indicators for allocated physical resources, wherein the physical shared channel allocation message relates to Time Division Duplex (TDD) mode; and
means for processing the plurality of sets of indicators for allocated physical resources and associated sets of indicators for transport format identifications contained in the received message, whereby a plurality of composite transport channels can be allocated with a single physical shared channel allocation message.
11. A computer readable medium encoded with computer program instructions for performing a process, the computer program instructions comprising instructions for:
receiving, at a radio unit, a sent physical shared channel allocation message, the message comprising a plurality of sets of indicators for allocated physical resources, and an associated set of transport format identifications for each of the sets of indicators for allocated physical resources, wherein the physical shared channel allocation message relates to Time Division Duplex (TDD) mode; and
processing the plurality of sets of indicators for allocated physical resources and the associated sets of indicators for transport format identifications contained therein, thereby allowing a plurality of composite transport channels to be allocated with a single physical shared channel allocation message.
