Abstract
A communications system is provided in which persistently allocated resources used by a node to communicate data with another node of the communications system can be reallocated or new dynamic resources can be allocated to allow the node to communicate using both the persistently allocated resources and the dynamically allocated resources. The system does this without changing the structure of a control channel used to communicate resource allocations.
Claims17
1-38. (canceled)
A method performed by a node of a communications system, the method comprising:
- storing allocation data defining persistently allocated resources for use in communicating data between the node and another node of the communications system within predetermined transmission time intervals;
- receiving control data relating to a dynamic allocation of resources to be used in a current transmission time interval;
- determining if the received control data includes a predefined bit pattern;
- and
- if the determining determines that the received control data does include the predefined bit pattern, then changing settings of the stored allocation data defining the persistently allocated resources;
- and if the determining determines that the received control data does not include the predefined bit pattern, then communicating with the other node using the dynamic allocation of resources defined by the received control data.
A method according to claim 38, wherein said control data includes HARQ data and wherein said predefined bit pattern is included in said HARQ data.
A method according to claim 38, wherein said control data includes modulation data and wherein said predefined bit pattern is included in said modulation data.
A method according to claim 38, wherein said control data includes ID data identifying the node, allocation data defining the allocated resources and transport format data and wherein said predefined bit pattern is defined by said transport format data.
A method performed by a node of a communications system, the method comprising:
- storing allocation data defining persistently allocated resources for use in communicating data between the node and another node of the communications system within predetermined transmission time intervals;
- generating control data relating to a dynamic allocation of resources to be used in a current transmission time interval;
- determining whether or not to include a predefined bit pattern within the control data, depending on whether or not the settings of the stored allocation data defining the persistently allocated resources are to be changed;
- transmitting the generated control data to the other node for controlling the resources used during the current transmission time interval;
- and
- depending on whether or not said control data includes said predefined bit pattern:
- i) communicating with said other node using the changed settings of the persistently allocated resources;
- or ii) communicating, within the current transmission time interval, with said other node using the dynamic allocation of resources defined by the transmitted control data.
A communications node comprising:
- a memory for storing allocation data defining persistently allocated resources for use in communicating data between the communications node and another node of a communications system within predetermined transmission time intervals;
- a receiver operable to receive control data relating to a dynamic allocation of resources to be used in a current transmission time interval;
- a controller operable:
- i) to determine if the received control data includes a predefined bit pattern;
- ii) to change settings of the stored allocation data defining the persistently allocated resources if the received control data does include the predefined bit pattern;
- and iii) to communicate with the other node using the dynamic allocation of resources defined by the received control data if the received control data does not include the predefined bit pattern, then.
A communications node comprising:
- a memory for storing allocation data defining persistently allocated resources for use in communicating data between the communications node and another node of a communications system within predetermined transmission time intervals;
- a controller operable:
- i) to generate control data relating to a dynamic allocation of resources to be used in a current transmission time interval;
- and ii) to determine whether or not to include a predefined bit pattern within the control data, depending on whether or not the settings of the stored allocation data defining the persistently allocated resources are to be changed;
- and
- a transmitter operable to transmit the generated control data to the other node for controlling the resources used during the current transmission time interval;
- and wherein the controller is operable so that depending on whether or not said control data includes said predefined bit pattern:
- i) to cause the communications node to communicate with said other node using the changed settings of the persistently allocated resources;
- or ii) to cause the communications node to communicate with said other node, within the current transmission time interval, using the dynamic allocation of resources defined by the transmitted control data.
