Abstract
A control apparatus predicts a probability distribution of radio quality when a downlink transmission from a base station to a radio terminal or an uplink transmission from a radio terminal to a base station is to be performed. The control apparatus calculates an expected value of a block error rate or reliability in the downlink or uplink transmission using the predicted probability distribution. The control apparatus determines a value of each of one or more parameters related to the downlink or uplink transmission, taking into account the calculated expected value.
Claims16
A control apparatus comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and configured to:
- predict a probability distribution of radio quality when a downlink transmission from a base station to a radio terminal, or an uplink transmission from a radio terminal to a base station, is to be performed;
- calculate an expected value of a block error rate (BLER) or reliability in the downlink or uplink transmission using the probability distribution;
- and
- determine a value of each of one or more parameters related to the downlink or uplink transmission, taking into account the expected value, to satisfy both of:
- the BLER or reliability requirement imposed on the downlink or uplink transmission;
- and
- a delay requirement imposed on the downlink or uplink transmission.
A method performed by a control apparatus, the method comprising:
- predicting a probability distribution of radio quality when a downlink transmission from a base station to a radio terminal, or an uplink transmission from a radio terminal to a base station, is to be performed;
- calculating an expected value of a block error rate (BLER) or reliability in the downlink or uplink transmission using the probability distribution;
- and
- determining a value of each of one or more parameters related to the downlink or uplink transmission, taking into account the expected value, to satisfy both of:
- a BLER or reliability requirement imposed on the downlink or uplink transmission;
- and
- a delay requirement imposed on the downlink or uplink transmission.
A non-transitory computer readable medium storing a program for causing a computer to perform a method, wherein the method comprises:
- predicting a probability distribution of radio quality when a downlink transmission from a base station to a radio terminal, or an uplink transmission from a radio terminal to a base station, is to be performed;
- calculating an expected value of a block error rate (BLER) or reliability in the downlink or uplink transmission using the probability distribution;
- and
- determining a value of each of one or more parameters related to the downlink or uplink transmission, taking into account the expected value, to satisfy both of:
- a BLER or reliability requirement imposed on the downlink or uplink transmission;
- and
- a delay requirement imposed on the downlink or uplink transmission.
