Method of sensing

摘要

Wireless nodes for use in a radio system are provided. A wireless node for use in a radio system may include a transmit and receive unit configured to request sensing information of at least one radio resource from at least one other wireless node of the radio system, and to receive the sensing information of the at least one radio resource from the at least one other wireless node of the radio system. The wireless node may include a sensing unit configured to determine whether a particular radio resource among the at least one radio resource is free to use based on the sensing information received from the at least one other wireless node. Related methods are also provided.

1. A wireless node for use in a radio system, the wireless node comprising:
a transmit and receive unit configured to:
request sensing information of at least one radio resource from at least one other wireless node of the radio system, in response to a determination by the wireless node that a probability that the at least one radio resource is free to use is below a threshold; andreceive the sensing information of the at least one radio resource from the at least one other wireless node of the radio system; a controller configured to determine whether a particular radio resource among the at least one radio resource is free to use based on the sensing information received from the at least one other wireless node; and a sensing request forwarding unit configured to use time and location constraints included in a received sensing request message to determine whether to forward the received sensing request message to at least one adjacent wireless node; wherein the probability that the at least one radio resource is free to use comprises a first probability; wherein the controller is configured to determine whether the particular radio resource is free to use by calculating a second probability of whether the particular radio resource is free to use based on the sensing information received from the at least one other wireless node; and wherein the second probability corresponds to a confidence level that is higher than a confidence level of the first probability.
