A method for determining rise over thermal for a base station in a wireless communications system is provided. The method comprises receiving a first and second diversity signal, measuring the signal strength of the first and second diversity signals, and estimating the noise floor for the first and second diversity signals. The signal strength rise is determined for the first and second diversity signals based on the measured signal strength and estimated noise floor of the first and second diversity signals respectively. The rise over thermal is then determined based on the determined signal strength rise of the first and second diversity signals.

The present invention provides a method and an apparatus of wireless communication with at least one wireless unit The method includes detecting an indication of error in a plurality of traffic frames to control transmit power between at least a first and second forward link based on the indication of error. The method further includes receiving a plurality of consecutive traffic frames over at least two reverse links from a wireless unit to select a frame in soft handoff. To control transmit power, for example, a controller may perform reverse link error detection after frame selection. The controller detects a frame error to boost the transmit power, substantially correcting a link imbalance situation. In this way, by controlling transmit power in a spread spectrum wireless communication system to reduce call drops, a call drop rate may be significantly decreased while increasing capacity of radio frequency transmission.

The present invention provides a method of communication using at least one base station and at least one switch. The method includes allocating at least one resource of at least one backhaul connection between said at least one base station and said at least one switch based upon at least one indication of congestion associated with said at least one backhaul connection.

The present invention provides a method and an apparatus for communication with at least one wireless unit over a forward and a reverse link in a wireless network. The method includes receiving a feedback indication on at least a first channel over the forward link for reception of a transmission on at least a second channel over the reverse link, and adjusting transmit power of a wireless unit associated with the network based on the feedback indication. For example, a transmitter at a wireless unit associated with a spread spectrum wireless network, such as a code division multiple access cellular network, may control transmit power of in a reverse link. Specifically, the feedback indication for reception of a traffic or control channel over the reverse link may be received on a channel that is available on the forward link for another purpose than providing power control feedback. In this way, the transmitter performs reverse link power control at the wireless unit. By performing such reverse link power control, the transmitter obviates many conventional drawbacks associated with a receiver-centric power control in a feedback-based spread spectrum wireless communications system.

The present invention relates to a system and method for load sharing among multiple base stations using Network Initiated Handover (NIHO). In one embodiment, the method includes computing scores for qualified pairs of candidate mobile station and target base station for potential network initiated handover (NIHO), and selecting a pair of candidate mobile station and target base station based on the computed scores to handover the candidate mobile station of the selected pair from the serving base station to the target base station of the selected pair.
摘要:
A method of receiving data packets. In the method of receiving data packets, a determination is made as to whether a received data packet is received out of an expected order. If the determining step determines a received packet is out of the expected order, a time period is calculated to wait for one or more missing data packets based at least in part on an expected time of receiving the one or more missing data packets.
摘要:
The number of Reverse Activity Bits (RABs) equal to “1” per frame is a Congestion Overload (CO) metric used to determine whether the reverse link in a wireless communications system is in a congestion overload state due to a reverse link RF overload. When the value of the CO metric exceeds a first predetermined threshold that is indicative of a congestion overload condition, the system enters a block state where all new connection requests are blocked. Once in the block state, if the value of the CO metric does not decrease but continues to increase and exceeds a second higher threshold, the system enters a mute state. In the mute state a predetermined large percentage of existing active calls are muted. Specifically, a message is sent downlink to specific ATs instructing them to reduce their transmission rates to zero but to still maintain their active connections.
