Estimation of parameters used for determining a signal-to-interference measure at a wireless communication device

A network node configured to estimate parameters used for determining a signal-to-interference measure at a communication device served by a serving base station in a wireless communication network, the network node comprising:

• a processing unit;
• and
• a memory which, when executed by said processing unit, cause said network node to:
• acquire an estimate of channel condition between the communication device and the serving base station, and between the communication device and at least one base station of a neighbouring cell;
• estimate the signal-to-interference measure using the estimate of the respective channel conditions, and acquired output power and Physical Resource Block (PRB) utilization of each of the serving base station and the at least one base station of the neighbouring cell, to be complied with when communicating with the communication device;
• receive, from the communication device, an indication of quality of a channel via which the communication device is served by the serving base station;
• determine whether a change in the estimate of the signal-to-interference measure is required based on said indication of channel quality;
• and
• update the estimate of the channel condition between the communication device and the serving base station, or between the communication device and the at least one base station of a neighbouring cell, or between the communication device and the serving base station and between the communication device and the at least one base station of a neighbouring cell, to attain the required change in the estimate of the signal-to-interference measure.

A non-transitory computer-readable storage medium, having stored there on a computer program comprising computer-executable instructions which, when executed on a processing unit included in a node in a wireless communication network of estimating parameters used for determining a signal-to-interference measure at a communication device served by a serving base station, cause the node to perform operations comprising:

• acquiring an estimate of channel condition between the communication device and the serving base station, and between the communication device and at least one base station of a neighbouring cell;
• estimating the signal-to-interference measure using the estimate of the respective channel conditions, and acquired output power and Physical Resource Block (PRB) utilization of the serving base station and the at least one base station of the neighboring cell, to be complied with when communicating with the communication device;
• receiving, from the communication device, an indication of quality of a channel via which the communication device is served by the serving base station;
• determining whether a change in the estimate of the signal-to-interference measure is required based on said indication of channel quality;
• and
• updating the estimate of the channel condition between the communication device and the serving base station, or between the communication device and the at least one base station of a neighbouring cell, or between the communication device and the serving base station and between the communication device and the at least one base station of a neighbouring cell, to attain the required change in the estimate of the signal-to-interference measure.
