BACKOFF OPERATION IN CONNECTION WITH SPATIAL REUSE

摘要

A communication device receives a signal during a backoff period of a backoff procedure, wherein the communication device is part of a first communication network. In response to determining that i) the signal is valid, ii) the signal is from another communication network, and iii) the power level of the signal does not meet a threshold that is higher than a default threshold, the communication device continues a count of a backoff timer during reception of the signal. In connection with comparing the power level of the signal to the threshold higher than the default threshold, the communication device sets a transmit power level to a reduced power level that is lower than a default power level. The communication device transmits at a transmit power level that is less than or equal to the reduced transmit power level in response to the backoff timer expiring.

1. A method, comprising:
receiving, at a communication device, a signal during a backoff period of a backoff procedure, wherein the communication device is part of a first communication network; performing, at the communication device, the backoff procedure, including:
determining, at the communication device, whether i) the signal is valid, ii) the signal is from another communication network, and iii) a power level of the signal meets a threshold that a) is higher than a default threshold for the backoff procedure, and b) is for analyzing valid signals not from the first communication network,in response to determining that i) the signal is valid, ii) the signal is from another communication network, and iii) the power level of the signal does not meet the threshold, continuing a count of a backoff timer, at the communication device, during reception of the signal, the backoff timer for measuring a backoff time period, andin connection with comparing the power level of the signal to the threshold that is higher than the default threshold, setting, at the communication device, a transmit power level to be used when the communication device transmits responsive to the backoff timer expiring to a reduced power level that is lower than a default power level; and in response to the backoff timer expiring as part of the backoff procedure, causing the communication device to transmit at a transmit power level that is less than or equal to the reduced transmit power level.
