Abstract
In a wireless communication system, the uplink transmission of measurement reports may be scheduled based on an estimated time of when a measurement report will be ready for transmission. The estimated time may be calculated at a base station or user equipment.
Claims18
A method for scheduling link quality measurement reports associated with one or more cells of a wireless network wherein the method is implemented in a base station, the method comprising:
- estimating at the base station a first time at which a first link quality measurement report will be available at a user equipment;
- scheduling transmission of the first link quality measurement report from the user equipment to the base station based on the first estimated time, wherein scheduling the transmission of the first link quality measurement report comprises, transmitting, just prior to the first estimated time, a grant of uplink resources from the base station to the user equipment to enable the user equipment to transmit the link quality measurement report to the base station on an uplink channel;
- estimating at the base station a second time at which a second link quality measurement report will be available at the user equipment, where the second estimated time at which the second link quality measurement report will be available is based on a time interval between the first link quality measurement report and the second link quality measurement report;
- and
- scheduling at the base station transmission of the second link quality measurement report from the user equipment to the base station based on the second estimated time.
A system, implemented in a base station associated with a wireless network, for scheduling link quality measurement reports associated with one or more cells of the wireless network, the system comprising:
- a unit in the base station configured to estimate a first time at which a first link quality measurement report will be available at a user equipment;
- a unit in the base station configured to schedule transmission of the first link quality measurement report from the user equipment to the base station based on the first estimated time, wherein scheduling the transmission of the first link quality measurement report comprises, initiating the transmission, just prior to the first estimated time, a grant of uplink resources from the base station to the user equipment to enable the user equipment to transmit the link quality measurement report to the base station on an uplink channel:
- a unit in the base station configured to estimate a second time at which a second link quality measurement report will be available at the user equipment, where the second estimated time at which the second link quality measurement report will be available is based on a time interval between the first link quality measurement report and the second link quality measurement report;
- and
- a unit in the base station configured to schedule at the base station transmission of the second link quality measurement report from the user equipment to the base station based on the second estimated time.
A system, implemented in user equipment associated with a wireless network, for scheduling link quality measurement reports associated with one or more cells of the wireless network, the system comprising:
- an estimator configured to estimate a first time at which a first link quality measurement report will be available for transmission from the user equipment;
- a unit configured to, schedule transmission of the first link quality measurement report from the user equipment to a base station based on the first estimated time, wherein scheduling the transmission of the first link quality measurement report comprises,
- initiating the transmission of an uplink resource request just prior to the first estimated time from the user equipment to the base station, and
- initiating the transmission of the first link quality measurement report to the base station based on whether an uplink grant is received at the user equipment in response to the uplink resource request;
- a unit configured to estimate a second time at which a second link quality measurement report will be available at the user equipment, where the second estimated time at which the second link quality measurement report will be available is based on a time interval between the first link quality measurement report and the second link quality measurement report;
- and
- a unit configured to schedule transmission of the second link quality measurement report from the user equipment to the base station based on the second estimated time.
