Claim of US Patent No. 10,893,529

1. A method comprising:scanning, by a transceiver of a communication device, for cells within communication range of the communication device, the transceiver supporting a maximum transmit power;
determining an uplink transmit power limit of the transceiver associated with each one of the cells, the uplink transmit power limit based, at least in part, on the maximum transmit power;
determining, based on a proximity of a target, whether a local constraint is applicable to the communication device, each local constraint requiring uplink transmit power to be less than the maximum transmit power, and each local constraint representing a graduated degree of local constraint that corresponds to a specific degree of proximity of the target and that is associated with a different uplink transmit power limit;
in response to determining that the local constraint is applicable, cutting back the uplink transmit power limit to the uplink transmit power limit associated with the applicable local constraint;
prioritizing selection of the cells for connecting to the communication device, based at least in part on the respective uplink transmit power limit, by giving highest priority to a prioritized cell having a lowest cut back; and
connecting to the prioritized cell among the cells.
