Contention for channel access in wireless network |
摘要 |
A method, apparatus, and computer program for configuring channel sensing parameters of an apparatus are disclosed in this document. The method comprises providing a mapping between reception sensitivity thresholds for determining whether a radio channel is busy or available for channel access and time values affecting a back-off time representing a time interval the apparatus refrains from channel access upon determining that the radio channel is busy, wherein a first time value is mapped to a first reception sensitivity threshold and a second time value is mapped to a second reception sensitivity threshold such that when the first reception sensitivity threshold provides a higher probability for the apparatus to determine that the channel is busy than the second reception sensitivity threshold, the first time value provides the apparatus with a lower back-off time than the second time value; and selecting a combination of a reception sensitivity threshold and a time value mapped to each other. |

1. A method comprising:
providing, in an apparatus, mapping between reception sensitivity thresholds for determining whether a radio channel is busy or available for channel access and time values affecting a back-off time representing a time interval the apparatus refrains from channel access upon determining that the radio channel is busy, wherein a first time value is mapped to a first reception sensitivity threshold and a second time value is mapped to a second reception sensitivity threshold such that when the first reception sensitivity threshold provides a higher probability, than the second reception sensitivity threshold, of a determination that the channel is busy, the first time value provides the apparatus with a lower back-off time than the second time value; and selecting, by the apparatus, a combination of a reception sensitivity threshold and a time value mapped to each other. |
