Base station repeater

Operating a base station repeater having a power control function, the mobile terminal uplink transmit power decreases in response to an increase in signal strength of the uplink signal received at the network, including increasing the gain of the repeater (at 202, Fig. 5) in response to an increase in the uplink signal received above a threshold (Th1) for a time interval (T1), and subsequently decreasing the gain of the repeater (at 204, 206, Fig. 5) until the measured power in the uplink signal received exceeds a threshold (Th1) for a time interval (T1). Due to the power control function, increasing the gain of the repeater causes the transmit power of the mobile terminal, and hence the uplink signal received at the repeater, to decrease. Again, due to the power control function, decreasing the gain of the repeater causes the transmit power of the mobile terminal, and hence the uplink signal received at the repeater, to increase. If the threshold is not exceeded this is indicative of ...

POWER CONTROL FOR A WIRELESS COMMUNICATION SYSTEM UTILIZING ORTHOGONAL MULTIPLEXING

Techniques for adjusting transmit power to mitigate both intra-sector interference to a serving base station and inter-sector interference to neighbor base stations are described. The amount of inter-sector interference that a terminal may cause may be roughly estimated based on the total interference observed by each neighbor base station, channel gains for the serving and neighbor base stations, and the current transmit power level. The transmit power may be decreased if high interference is observed by a neighbor base station and increased otherwise. The transmit power may be adjusted by a larger amount and/or more frequently if the terminal is located closer to the neighbor base station observing high interference and/or if the current transmit power level is higher, and vice versa. The intra-sector interference is maintained within an acceptable level by limiting a received SNR for the terminal to be within a range of allowable SNRs.

MULTI-STAGE TRANSMIT POWER CONTROL SCHEME FOR ACCESS POINT

Transmit power for an access point is controlled based on information received by the access point (106). For example, an access point may employ one or more algorithms that use messages received from nearby access terminals (102, 104) to maintain an acceptable tradeoff between providing an adequate coverage area for access point transmissions and mitigating interference that these transmissions cause at nearby access terminals (104). Here, the access point may employ a network listen-based algorithm upon initialization of the access terminal to provide preliminary transmit power control until sufficient information is collected for another transmit power control algorithm (e.g., an access terminal assisted algorithm). Also, the access point may employ an active access terminal protection scheme to mitigate interference the access point may otherwise cause to a nearby access terminal (104) that is in active communication with another access point (108).
