20100105407 | WIRELESS TRANSMISSION POWER CONTROL METHOD AND SYSTEM - A wireless communication system includes a primary station which has a transmitter for transmitting wireless signals on a downlink, and a plurality of secondary stations each having a receiver for receiving signals on the downlink and a transmitter for transmitting on an uplink. In a normal, loaded condition a synchronization channel and a data channel are present on the downlink and closed power control is achieved by measuring the signal to interference ratio (SIR) in a received downlink transmission, comparing the measured SIR with a target SIR and sending a power adjust indication on the uplink to cause the primary station to adjust its transmitted power on the downlink. The secondary station monitors the downlink and, in response to detecting an unloaded cell condition, determines a target SIR offset which it applies to the target SIR to overcome interference from the presence of the synchronization channel on the downlink. | 04-29-2010 |
20110122931 | RECEIVE DIVERSITY SYSTEMS - A diversity receiver and a method of recovering symbols in a diversity receiver system comprises receiving first and second signals at first and second antenna elements.
