A home base station receives signal to interference and noise ratio data from at least one access terminal, determines whether a transmission power of the home base station should be adjusted based on the received signal to interference and noise ratio data, and then adaptively adjusts the transmission power of the home base station based on the received signal to interference and noise ratio data.

Adjusting wireless signal transmission power

In addition to other aspects disclosed, a portable base station requests assignment of a portion of a code space from a remotely located control station. The assignment is based upon the location of the portable base station. The portable base station is also capable of transmitting an identification signal using the assigned code space portion to uniquely identify the portable base station to one or more access terminals.

Assigning code space to portable base stations

In addition to other aspects disclosed, a data over signaling message that identifies a recipient access terminal is transmitted from a radio network controller to the sector in response to an attempt by an access terminal on a sector of a wireless network to access a service of the wireless network.

Signaling for push-to-talk

In a radio access network in which a first access terminal uses a first access point to access the network and a second access terminal uses a second access point to access the network, interference is reduced in communications between the first access terminal and the first access point by adjusting signal power levels of the second access terminal without requiring coordination between the first and second access points.

Controlling reverse link interference in private access points for wireless networking

Information is received identifying a geographic location of an access point in a radio access network. Access information is assigned and communicated to the access point, and the access information and the geographic location information is communicated to an access terminal. The access terminal identifies the access point as a preferred access point, including its geographic location. The access terminal receives information identifying its own geographic location, and when the access terminal is near the access point, the access point is used to access the network. The access point receives information identifying its geographic location and communicates the geographic location information to a configuration server. The access point receives access information from the configuration server and provides access terminals access to the network using the access information.

Configuring preferred user zone lists for private access points for wireless networking

The description describes examples for performing reverse link power control in a mobile network having a plurality of first modem devices that receive and transmit signals to wireless access terminals (ATs) and a second device in communication with the plurality of first devices. Execution is transitioned between a first and a second loop to control reverse link power of one of the ATs. The transition is based on a state of a connection. The first control loop executes at one of the first devices and the second loop executes at the second device.

Reverse link power control

This description describes examples of performing reverse link power control in a mobile network having a plurality of first modem devices that receive and transmit signals to wireless access terminals (ATs) and a second device in communication with the plurality of first devices. One of the first devices derives a first power control threshold (PCT) value for reverse link power of one of the access terminals (ATs) and the second device derives a second power control threshold (PCT) value for reverse link power of the one of the ATs. The second power control threshold (PCT) value is transmitted using a data traffic path and either the first PCT value or the second PCT value is selected.

In a radio access network (e.g., a cellular network), a radio receiver is configured with a switch that alternatively couples an antenna and an impedance-matched load to the remainder of the receiver. Sector load, e.g., rise-over-thermal (ROT), is monitored by comparing a first measurement of signal power in a radio receiver (e.g., signal power output by the receiver) when the radio receiver is coupled to an antenna receiving the data traffic with a second measurement of signal power in the radio receiver when the radio receiver is de-coupled from the antenna.

Measuring interference in radio networks

A device causes at least one access terminal that is configured to transmit data to a radio node in a sector of a radio access network to alter transmission. While transmission is altered, the device determines a power of a signal received at the radio node, and updates an average value of signal power using the power measured. A device receives, from one or more access terminals that are configured to receive data from a radio node in a sector of a radio access network, a requested rate at which information should be transmitted to each access terminal, receives from the access terminals information about quality of signals received from the radio node, and generates an event if the requested rate and the information about quality of signals fail to satisfy a condition. An access terminal, located in the vicinity of a first radio node configured to transmit data in a sector of a radio access network, measures signal power of pilot signals received by the access terminal.

Detection of radio frequency interference in wireless communication systems

In a radio access network, the reverse link rate of an access terminal is controlled and stabilized by determining a number of connections in one or more sectors in which the access terminal has a connection and setting a rate limit based on at least one of the determined number of connections. The number of connections can be determined for each sector in which the access terminal has a connection or for some subset of these sectors. If the number of connections is determined for more than one sector, the radio access network may limit the reverse link rate based on the sector having the greatest number of connections.
