Uplink power control scheme for distributed RRH systems with same cell ID

A method, comprising:

• receiving at a wireless device a reference signal transmitted from a base station device within a macro cell in a wireless network, wherein the base station device and at least one radio transmitter device being communicatively coupled to and remote from the base station device are disposed within the macro cell, the base station device and one or more radio transmitters devices being a transmission point, or a reception point, for the one or more wireless devices within the cell;
• receiving at least one wireless device information relating to a transmission power of the base station device;
• receiving from the base station device a filter coefficient value for a signal power measurement made by the wireless device, wherein the filter coefficient is set to a maximum value if a strength of the uplink signal at the base station device is greater than or equal to a total strength of the uplink signal at one or more radio transmitter devices plus a threshold, otherwise the filter coefficient is set to a default value;
• performing path loss estimation and smoothing the path loss estimation with a filter using the filter coefficient value;
• determining a transmission point for the wireless device within the macro cell;
• and
• transmitting from the wireless device an uplink signal containing information relating to an uplink power determination that is based on the received reference signal and the received information relating to the transmission power of the base station device, wherein the uplink power determination is based at least in part on the path loss estimation.

A base station, comprising:

• at least one radio-frequency transceiver;
• and
• a processor coupled to the at least one radio-frequency transceiver, the processor configured to:
• transmit a reference signal to at least one wireless device within a macro cell in a wireless network;
• transmit to the at least one wireless device information relating to a transmission power;
• measure at the base station device a received strength of the uplink signal from the at least one wireless device;
• determine a filter coefficient value based at least in part on the received strength of the uplink signal, wherein the filter coefficient is set to a maximum value if a strength of the uplink signal at the base station device is greater than or equal to a total strength of the uplink signal at one or more radio transmitter devices plus a threshold, otherwise the filter coefficient is set to a default value;
• transmit the filter coefficient value for received strength measurement to the at least one wireless device;
• receive from the at least one wireless device an uplink signal containing information relating to an uplink power determination that is based on the reference signal received by the at least one wireless device and the information relating to the transmission power of the base station received by the at least one wireless device;
• transmit to the at least one wireless device the information relating to the filter coefficient value for a signal power measurement made by the at least one wireless device, wherein the filter coefficient value is used to by the wireless device to determine an uplink power setting from the wireless device to the base station or to at least one radio transmitter device disposed in the macro cell, wherein the uplink power setting is determined based at least in part on a path loss estimation that is smoothed with a filter using the filter coefficient value.
