Abstract
An entity, such as a base station, in a wireless communications network performs power control of a control channel based on one or more characteristics of a message in the control channel. For example, the control channel can be a paging channel. The one or more characteristics include, as examples, the size and/or the type of message in the control channel.
Claims17
A method for performing wireless communications in a mobile communications network, comprising:
- a communication device determining a message to be communicated in a control channel;
- the communication device determining a power level for transmission of the message using the control channel, wherein said determining the power level comprises setting different power levels for different types of messages carried in the control channel, wherein a specific power level is determined based on the message being an acknowledgement message, and wherein the power level for the acknowledgement message is a default power level and wherein a power level for at least one other message of a type different than the acknowledgement message is different than the default power level;
- the communication device setting the power level for transmission of the message based on said determining;
- and
- after setting the power level for transmission, the communication device transmitting the message in the control channel using the determined power level.
A communication device for performing wireless communicating, comprising:
- communication circuitry for performing the wireless communication;
- processing hardware coupled to the communication circuitry, wherein the controller is configured to operate with the communication circuitry to:
- determine a message to be communicated in a control channel;
- determine a power level for transmission of the message using the control channel, wherein said determining the power level comprises setting different power levels for different types of messages carried in the control channel, wherein a specific power level is determined based on the message being an acknowledgement message, and wherein the power level for the acknowledgement message is a default power level and wherein a power level for at least one other message of a type different than the acknowledgement message is different than the default power level;
- set the power level for transmission of the message based on said determining;
- and
- after setting the power level for transmission, transmit the message in the control channel using the determined power level.
A non-transitory, computer accessible memory medium storing program instructions for performing wireless communications in a mobile communications network, wherein the program instructions are executable by a processor of a communication device to:
- determine a message to be communicated in a control channel;
- determine a power level for transmission of the message using the control channel, wherein said determining the power level comprises setting different power levels for different types of messages carried in the control channel, wherein a specific power level is determined based on the message being an acknowledgement message, and wherein the power level for the acknowledgement message is a default power level and wherein a power level for at least one other message of a type different than the acknowledgement message is different than the default power level;
- set the power level for transmission of the message based on said determining;
- and
- after setting the power level for transmission, transmit the message in the control channel using the determined power level.
