Abstract
A mobile terminal for use in a cellular communications network the terminal being adapted to: i) if the terminal transmits signals at a power below the maximum uplink transmission power, distributing the available uplink transmission power between different channels according to a first scheme; and ii) if the terminal transmits signals at a power exceeding or about to exceed the maximum uplink transmission power, distributing the available uplink transmission power between different channels according to a second scheme different from said first scheme.
Claims21
A mobile terminal for use in a cellular communications network the terminal being adapted to:
- i) if the terminal transmits signals at a power below a maximum uplink transmission power, distributing an available uplink transmission power between different channels according to a first scheme;
- and
- ii) if the terminal transmits signals at a power exceeding or about to exceed the maximum uplink transmission power, distributing the available uplink transmission power between different channels according to a second scheme different from said first scheme.
A network element of a cellular communications network, the network element being adapted to determine one or more parameters defining a distribution of uplink transmission power between different channels if a maximum uplink transmission power is exceeded or about to exceeded, wherein at least one of said parameters are different from parameters defining the distribution if the maximum uplink transmission power is not exceeded.
A method for data transmission in a communication system, comprising steps of:
- distributing transmission powers of channels transmitted by a first transceiver side;
- monitoring whether a total transmission power of the first transceiver exceeds a maximum transmission power, where the total transmission power of the first transceiver is a sum of transmission powers of each of the channels;
- re-distributing transmission powers of the channels by scaling down a transmission power of a channel having a low priority, when the total transmission power of the first transceiver exceeds the maximum transmission power;
- and
- transmitting the channels to a second transceiver side through the re-distributed transmission powers.
