Abstract:
1. A mobile station for communicating in a wireless communication network, the mobile station comprising: at least one receiver and at least one transmitter, for communicating with a base station in the wireless communication network; a first unit configured to monitor activity in the wireless communication network; a second unit configured to detect collisions in the communication network; a third unit configured to determine parameters indicative of a channel quality on a first radio channel; and wherein the mobile station is configured to estimate a probability of collisions on the first radio channel based on one or both of the monitored activity and the detected collisions, and further wherein the mobile station is configured to communicate with the base station via a separate radio channel, instead of the first radio channel, when the parameters indicative of the channel quality on the first radio channel fall below a first predefined threshold value, or when the estimated probability of collisions on the first radio channel exceeds a second predefined threshold value.
