Abstract
A radio network controller, RNC, keeps control of how many users to configure on a first transmission time interval, TTI, and how many to configure on a second TTI. For example, a method, performed by the RNC, for configuring at least one radio bearer between a radio base station, RBS, and wireless communication devices. The method comprises receiving, from the RBS, a request to perform a TTI switch according to a TTI switch trigger received by the RBS. The received request is analyzed and a grant to perform the requested TTI switch is sent to the RBS.
Claims15
A method, performed by a radio network controller (RNC) for configuring at least one radio bearer between a radio base station (RBS) and wireless communication devices, the method comprising:
- receiving, from the RBS, a request to perform a transmission time interval (TTI) switch according to a TTI switch trigger received by the RBS from a wireless communication device;
- analysing the received request;
- sending, to the RBS, a grant to perform the requested TTI switch;
- and
- receiving information from the RBS regarding any of:
- information that the wireless communication device using a first TTI in a radio bearer is to be switched to using a second TTI;
- and
- information that the wireless communication device using the second TTI in a radio bearer is to be switched to using the first TTI.
A method performed by a radio base station (RBS), for configuring at least one radio bearer between the RBS and wireless communication devices, the method comprising:
- receiving, from a wireless communication device, any of:
- a transmission time interval (TTI) switch trigger that indicates a request from the wireless communication device to switch from operating a radio bearer using a first TTI to operating a radio bearer using a second TTI;
- and
- a TTI switch trigger that indicates a request from the wireless communication device to switch from operating a radio bearer using the second TTI to operating a radio bearer using the first TTI;
- and
- sending to a radio network controller (RNC) a request to perform a TTI switch according to the received TTI switch trigger;
- receiving a grant from the RNC to perform the requested TTI switch;
- and
- performing the requested TTI switch.
A radio network controller (RNC) comprising input/output circuitry, a processor and a memory, said memory containing instructions executable by said processor, whereby said RNC is operative to configure at least one radio bearer between a radio base station (RBS) and wireless communication devices, based on being configured to:
- receive a request from the RBS to perform a transmission time interval (TTI) switch according to a TTI switch trigger received by the RBS from a wireless communication device;
- analyse the received request;
- send a grant to the RBS, to perform the requested TTI switch;
- and
- receive information from the RBS regarding any of:
- information that the wireless communication device using a first TTI in a radio bearer is to be switched to using a second TTI;
- and
- information that the wireless communication device using the second TTI in a radio bearer is to be switched to using the first TTI.
A radio base station (RBS) comprising radio circuitry, a processor and a memory, said memory containing instructions executable by said processor whereby said RBS is operative to configure at least one radio bearer between the RBS and wireless communication devices, based on being configured to:
- receive from a wireless communication device any of:
- a transmission time interval (TTI) switch trigger that indicates a request from the wireless communication device to switch from operating a radio bearer using a first TTI to operating a radio bearer using a second TTI;
- and
- a TTI switch trigger that indicates a request from the wireless communication device to switch from operating a radio bearer using the second TTI to operating a radio bearer using the first TTI;
- and
- send, to a radio network controller (RNC), a request to perform a TTI switch according to the received TTI switch trigger;
- receive a grant from the RNC to perform the requested TTI switch;
- and
- perform the requested TTI switch.
A non-transitory computer-readable medium storing a computer program comprising instructions which, when, executed on at least one processor in a radio network controller (RNC), configures the RNC to configure at least one radio bearer between a radio base station (RBS) and wireless communication devices, based on said computer program comprising program instructions configuring the RNC to:
- receive a request from the RBS to perform a transmission time interval (TTI) switch according to a TTI switch trigger received by the RBS from a wireless communication device;
- analyse the received request;
- send a grant to the RBS, to perform the requested TTI switch;
- and
- receiving information from the RBS regarding any of:
- information that the wireless communication device using a first TTI in a radio bearer is to be switched to using a second TTI;
- and
- information that the wireless communication device using the second TTI in a radio bearer is to be switched to using the first TTI.
A non-transitory computer-readable medium storing a computer program comprising instructions which, when executed on at least one processor in a radio base station (RBS), configures the RBS to configure at least one radio bearer between the RBS and wireless communication devices, based on said computer program comprising program instructions configuring the RBS to:
- receive from a wireless communication device any of:
- a transmission time interval (TTI) switch trigger that indicates a request from the wireless communication device to switch from operating a radio bearer using a first TTI to operating a radio bearer using a second TTI;
- and
- a TTI switch trigger that indicates a request from the wireless communication device to switch from operating a radio bearer using the second TTI to operating a radio bearer using the first TTI;
- and
- send, to a radio network controller (RNC), a request to perform a TTI switch according to the received TTI switch trigger;
- receive a grant from the RNC to perform the requested TTI switch;
- and
- perform the requested TTI switch.
