Abstract: To perform wireless communications in a wireless network, at least two spatial beams are formed within a cell segment, where the at least two spatial beams are associated with different power levels. The at least two spatial beams are swept across the cell segment according to a sweep pattern. In some implementations, multiple antenna assemblies can be used, where each antenna assembly has plural antenna elements. A lower one of the antenna assemblies can be used to form high and lower power beams, and an upper one of the antenna assemblies can be used to communicate backhaul information, for example.

Abstract: Disclosed is an air interface protocol architecture for a multi-carrier wireless communications network having a plurality of carriers. The protocol architecture comprises a common layer 2/3 protocol for each of the carriers. The common layer 2/3 protocol provides a common interface with wireline upper level protocols. In addition to the common layer 2/3 protocol, the architecture comprises a multimode physical layer for each of the carriers. The protocol architecture enables the physical layer of each carrier may have a different protocol configuration for each mobile station serviced by the carrier. Each air interface protocol instance includes one or more resource pools. The resource pools each includes: (1) a quality of service (QoS) supported; (2) a list of manageable resources; (3) a carrier identification; and (4) an air interface configuration. Additionally, the layer 2 protocol of the common layer 2/3 protocol includes one or more Radio Link Protocol (RLP) instances (or a QoS Link Protocol) and one or more Medium Access Control (MAC) sublayer instances.

Abstract: A base station, mobile station, and/or other terminal device includes physical layer (layer 1) protocol and link layer (layer 2) protocol that both include automatic retransmission request (ARQ) operations. The physical layer and link layer include enhancements that interact with one another to cause the link layer to inhibit ARQ operations while error recovery operations are pending at the physical layer. A transmitter packages link layer packet data units into physical layer frames and transmits the physical layer frames. A receiver responds to indicate either successful or unsuccessful transmission. The transmitting physical layer waits for the response and initiates error recovery operations when required. The receiving link layer, when it detects lost data packets, inhibits its ARQ operations to allow physical layer error recovery operations to complete.

Abstract: An access network controller and a base station controller are formed to define an interface there between that enables the two systems to facilitate and respond to a voice call that is to be set up to a hybrid mobile station even though the hybrid mobile station is presently engaged in a data only call. More specifically, the base station is formed to generate a pseudo-page signal to the access network controller to determine whether the hybrid mobile station is present and available prior to the base station generating paging signals to establish the voice call. According to the response received from the access network controller, the base station either pages the hybrid mobile station to establish the voice call, forwards the call to voice mail, or forwards the call either to an Internet Call Delivery Server or to an Internet Call-Waiting Server.

Abstract: A method and apparatus for the transmission of short data bursts in CDMA/HDR networks. Dormant access terminals are assigned to a common traffic channel and rate group by an access point. The access point then informs the access terminals of the assigned common traffic channels and rate groups. The access point then transmits short data bursts to the dormant access terminals using the assigned common traffic channels and rate groups. If an access terminal fails to acknowledge receipt of a short data burst, then the access terminal is re-assigned to a new common traffic channel and rate group and transmission of the short data bursts is re-attempted. If an access terminal fails to acknowledge receipt of a short data burst more than a predetermined number of times, then the access terminal is placed in an active mode of operation. The transmission of short data bursts may be further assigned to time slots within the common traffic channels and rate groups in order to conserve the resources of the access terminals.

Abstract: A base station controller includes circuitry for determining whether a transmitter is transmitting in a DTX mode or operation for a supplemental channel in a CDMA network. The invention includes the steps of determining frame quality metrics for data received on a fundamental and a supplemental channel. If the frame quality metric is good, meaning that the number of errors is below a defined threshold, on the supplemental channel, then the mobile station is not, by definition, within a DTX mode of operation. However, if each of the base stations that are on the active list of base stations for the mobile station report that the mobile station frame quality metric is not below or within a specified threshold, then the base station performs a calculation to determine whether the mobile station is in a DTX mode of operation or is transmitting a null set. Specifically, the base station calculates a signal to noise ratio for the pilot channel as well as for the supplemental channel and compares or determines a ratio of these two calculations. If the ratio is within or below a specified threshold, then an erasure has occurred. If not, then the mobile station did transmit in a DTX mode of operation.

Abstract: System components of cellular wireless networks are shared during and after a mobile station handover from a first cellular wireless network (system A) to a second cellular wireless network (system B). According to one aspect, layer 2/3 call control functions are anchored in a base station controller (BSC) of system A, even after a data communication is handed over from system A to system B. According to another aspect, a link layer supporting the data communication is anchored in the BSC of system A servicing the data communication. In this case, the BSC of system A interfaces with a serving BTS of system B to service the ongoing data communication. According to still another aspect, the link layer is handed over to system B but the link layer of system B continues to use a link layer transmit buffer of system A that remains in the servicing BSC of system A.

Abstract: Embodiments describe example radio access networks where uplink and downlink communications operate asymmetrically. In one embodiment, an inverse fast Fourier transform and an add cyclic prefix operation is performed on a downlink communications by a baseband unit. In an uplink communication using the same baseband unit, a corresponding fast Fourier transform and a remove cyclic prefix operation are performed at a remote radio unit. This generates different levels of traffic on a physical communication link between the baseband unit and the remote radio unit for uplink and downlink communications with similar characteristics.
