Abstract
A radio system (110) comprising a first (120) and a second (130) radio unit which comprise a transmitter (122, 132) and a receiver (121, 131). The first radio unit (120) communicates with a first external radio unit (101) and the second radio unit (140) with a second external radio unit (102). Both transmitters (122, 132) are arranged to vary their output power level in response to a request from the external radio unit with which they are arranged to communicate. Both of the transmitters also vary their output power level in response to a variation in the transmitter output power level of the other radio unit.
Claims25
A radio system comprising:
- at least a first and a second radio unit, both of which radio units comprise a transmitter and a receiver;
- the first radio unit arranged to communicate with a first external radio unit and the second radio unit arranged to communicate with a second external radio unit;
- and
- and the transmitters of both the first and the second radio units arranged to vary the output power level respective output power levels of their transmissions in response to a request communication from the external radio unit with which they are arranged to communicate, with both of said transmitters also being arranged to vary the output power level respective output power levels of their transmissions in response to a variation in the output power level of the transmitter of the other of the first and second radio unit, so that a requested variation in the output power level of one of the transmitters results in a variation in the output power level of both transmitters, wherein both radio units are arranged to enable their transmitters to use a larger of an increase in a variation in the output power level specified in a request from both of the first and second external radio units, wherein the request includes the variation which is an increase during the same time period both of said transmitters also being arranged to vary the respective output power levels of their transmissions such that, when a communication from the first external radio unit would cause a first increase value in output power level at the first radio unit in a time period, and a communication from the second external radio unit would cause a second increase value in output power level at the second radio unit during the time period, both the first and the second radio units use a larger of the first increase value and the second increase value to vary the respective output power levels of their transmissions.
A method for use in a radio system , system, comprising the use of at least a first radio unit in order to communicate with a first external radio unit and a second radio unit in order to communicate with a second external radio unit, both of said radio units comprising a transmitter and a receiver, the method comprising:
- enabling the transmitters of both the first and the second radio units to vary the output power level respective output power levels of their transmissions in response to a request communication from the external radio unit with which they communicate;
- and enabling both of said transmitters to vary the output power level respective output power levels of their transmissions in response to a variation in the output power level of the transmitter of the other of the first and second radio unit, so that a requested variation in the output power level of one of the transmitters results in a variation in the output power level of both transmitters, wherein both radio units enable their transmitters to use the larger increase in the case that both of the first and second external radio units request a variation which is an increase during the same time period of said transmitters also being arranged to vary the respective output power levels of their transmissions such that, when a communication from the first external radio unit would cause a first increase value in output power level at the first radio unit in a time period, and a communication from the second external radio unit would cause a second increase value in output power level at the second radio unit during the time period, both the first and the second radio units use a larger of the first increase value and the second increase value to vary the respective output power levels of their transmissions.
A radio system comprising:
- at least a first and a second radio unit, both of which radio units comprise a transmitter and a receiver;
- the first radio unit arranged to communicate with a first external radio unit and the second radio unit arranged to communicate with a second external radio unit;
- and
- the transmitters of both the first and the second radio units arranged to vary respective output power levels of their transmissions in response to a communication from the external radio unit with which they are arranged to communicate, with both of said transmitters also being arranged to vary the respective output power levels of their transmissions in response to a variation in the output power level of the transmitter of the other of the first and second radio unit, so that, when a communication from one of the first or the second external radio units would cause a variation in the output power level of the transmitter with which it is arranged to communicate, the variation in the output power level of one of the transmitters results in the variation in the output power level of both transmitters.
A method for use in a radio system, comprising the use of at least a first radio unit in order to communicate with a first external radio unit and a second radio unit in order to communicate with a second external radio unit, both of said radio units comprising a transmitter and a receiver, the method comprising:
- enabling the transmitters of both the first and the second radio units to vary respective output power levels of their transmissions in response to a communication from the external radio unit with which they communicate;
- and
- enabling both of said transmitters to vary the respective output power levels of their transmissions in response to a variation in the output power level of the transmitter of the other of the first and second radio unit, so that when a communication from one of the first or the second external radio units would cause a variation in the output power level of the transmitter with which it is arranged to communicate, the variation in the output power level of one of the transmitters results in the variation in the output power level of both transmitters.
