Abstract
A method of scheduling transmission of data in a wireless communication network comprising: establishing a data channel for transmitting user data from a user equipment to a network entity, establishing a signalling channel for transmitting signalling data from a user equipment to a network entity, transmitting over said signalling channel from the user equipment a first rate request message requesting additional resources from the network for transmission of data at an increased data rate over said data channel, maintaining said signalling channel for a period awaiting a rate grant message, and transmitting a second rate request message over said signalling channel during said period.
Claims21
An apparatus, comprising:
- a transmitter configured to transmit over a signalling channel, a first rate request message that requests additional resources from a network entity for transmission of data at an increased data rate over a data channel;
- a channel maintainer configured to maintain said signalling channel for a period;
- and
- wherein the transmitter is further configured to transmit a second rate request message over said signalling channel during said period, wherein the second rate request message is a repeat of the first request message, and
- wherein the first rate request message is a single reserved bit transmitted together with other uplink signalling information and the single reserved bit has a value selected from a first value indicating that the increased data rate is required and a second value indicating that a current rate of data transmission over the data channel is sufficient.
An apparatus, comprising:
- a receiver configured to receive a first rate request message from a user equipment, wherein the first rate request message is a single reserved bit sent together with other uplink signaling information, and the single reserved bit has a value selected from a first value indicating that the user equipment requires an increased data rate and a second value indicating that a current rate of data transmission over the data channel is sufficient,
- a determiner configured to determine within a predetermined time period whether a rate grant message is issued based on network resources and based on the value of the single reserved bit, and
- an issuer configured to issue said rate grant message if there are adequate network resources and the single reserved bit has the first value,
- wherein a subsequent rate request message received during said predetermined time period is ignored, wherein the subsequent rate request message is a repeat of the first rate request message.
A method, comprising:
- receiving a first rate request message from a user equipment, wherein the first rate request message is a single reserved bit sent together with other uplink signaling information, and the single reserved bit has a value selected from a first value indicating that the user equipment requires an increased data rate and a second value indicating that a current rate of data transmission over the data channel is sufficient,
- determining, within a predetermined time period, whether a rate grant message is issued based on network resources and based on the value of the single reserved bit,
- issuing said rate grant message if there are adequate network resources and the single reserved bit has the first value, and
- ignoring a subsequent received rate request message, wherein the subsequent rate request message is a repeat of the first rate request message.
