Abstract
The invention describes a method of controlling transmission power in a telecommunications system comprising a first and a second transceiver. In the presented method, one power control command is transmitted during at least two time-slots from the second transceiver to the first transceiver and the one power control command is received at the first transceiver during at least two time-slots.

A method of controlling transmission power in a telecommunications system, comprising:
- a message structure comprising time-slots, the system comprising a first transceiver and a second transceiver, the method further comprising:
- controlling the transmission power of the a first transceiver (101) based on a received power control command received in a time-slot of a message structure from a second transceiver, wherein the message structure comprises time-slots, and
- dividing one power control command into at least a first part and a second part to be transmitted respectively in at least two time-slots from the second transceiver to the first transceiver, the first part transmitted in a first time-slot and the second part transmitted in a second time-slot, and
- receiving said one power control command at the first transceiver during at least two time-slots by receiving said first part from said first time-slot and said second part from said second time-slot, combining said first part and said second part to reform said one power control command, and using said reformed one power control command to make a single-increment power adjustment.
A telecommunications system, wherein a message structure comprising time-slots is used, the system comprising a first transceiver (101) and a second transceiver (100) , wherein the first transceiver (101) is configured to control transmission power based on a received power control command,
- the second transceiver is configured to divide one power control command into a first part and a second part for transmission respectively in at least two time-slots to the first transceiver, and
- the first transceiver is configured to receive said first part and said second part and, thereafter upon receipt, reform said received first and second parts into said one power control command during at least two time-slots, wherein,
- said reformed one power control command is used to make a power adjustment.
A method of controlling transmission power in a telecommunications system, in which a message structure comprising time-slots is used, the system comprising a first transceiver and a second transceiver, the method comprising controlling the transmission power of the first transceiver (101) based on a received power control command, the method comprising the steps of:
- dividing one power control command into plural divided command parts so power control bits that make up the one power control command are divided into the plural divided command parts;
- transmitting, from the second transceiver to the first transceiver, each divided command part in a different one of at least two time-slots so that different parts of the power control bits that make up the one power control command are transmitted in different ones of the at least two time-slots;
- receiving, at the first transceiver during different time-slots, each of the divided command parts and using the received divided command parts to reform the one power control command;
- and
- controlling the transmission power of the first transceiver, in a single increment power change, based on the reformed one power control command comprised of the received divided command parts.
A method of controlling transmission power in a telecommunications system, the method comprising:
- at a second device, determining a value of a power adjustment level for a first device for inclusion in a power control command to the first device;
- defining values for a plurality of bits based on the determined value;
- dividing the defined values for the plurality of bits into a plurality of bit sets, wherein a bit set of the plurality of bit sets includes at least one bit;
- and
- transmitting each of the plurality of bit sets to the first device from the second device during different timeslots, wherein the plurality of bit sets are associated with the power control command.
A method of controlling transmission power in a telecommunications system, the method comprising:
- receiving a plurality of bit sets at a first device from a second device, each bit set of the plurality of bit sets received during different timeslots;
- determining a value of a power adjustment level for the first device by combining the received plurality of bit sets into a plurality of bits;
- and
- controlling a transmission power of a transceiver of the first device based on the determined value.
A device comprising:
- a transceiver configured to determine a value of a power adjustment level for a second device for inclusion in a power control command to the second device;
- to define values for a plurality of bits based on the determined value;
- and
- to divide the defined values for the plurality of bits into a plurality of bit sets, wherein a bit set of the plurality of bit sets includes at least one bit;
- and
- an antenna configured to transmit each of the plurality of bit sets to the second device during different timeslots, wherein the plurality of bit sets are associated with the power control command.
A device comprising:
- an antenna configured to receive a plurality of bit sets from a second device, each bit set of the plurality of bit sets received during different timeslots;
- and
- a transceiver configured to determine a value of a power adjustment level for the first device by combining the received plurality of bit sets into a plurality of bits;
- and
- to determine a transmission power adjustment for the transceiver based on the determined value.
