A method and apparatus may predict a link quality. The method may also include determining a primary cell for a user equipment based on the predicted link quality. The determining the primary cell comprises determining whether the user equipment should be served by a time-division-duplex carrier or by a frequency-division-duplex carrier. The method may also include determining a carrier aggregation to be used by the user equipment based on the predicted link quality.

Method and apparatus for management of frequency-division-duplex and time-division-duplex carrier aggregation

In accordance with the exemplary embodiments of the invention there is at least a method and apparatus to perform operations of receiving, by an access node, from a user equipment a physical cell identity of a neighbor cell in a communication network; determining information including at least one of an angle of arrival and UE Rx-Tx time difference with respect to the user equipment of the communication network; and storing the determined information in a neighbor relation table to use in network operations.

Method to optimize PCI confusion detection and resolution

A method to perform successful RRC reestablishment across eNB seams in ping pong scenarios without data loss is described. The method includes, during a handover procedure of a UE from a source AP to a target AP, receiving, at the source AP, a reestablishment request from the UE. The reestablishment request includes a temporary identity assigned by the target AP for the UE. The method also includes determining a UE context based on the temporary identity assigned by the target AP and performing a reestablishment procedure between the source AP and the UE. Apparatus and computer readable media are also described.

Method to improve reestablishment success rate in LTE system-at source ENB during ping pongs

A method and network controller () with a radio network controller () that transmits () a first signaling message to a communication device (). The first signaling message includes extended information that some communications devices () are expected to be unable to process. The radio network controller () further transmits () a second signaling message that includes substantially all information that is contained within the first signaling message except for the extended information. The method and network controller () also includes a signaling message retransmission controller () communicatively coupled to the network controller, that identifies information contained within the extended information and indicates the extended information to the radio network controller ().

System and method for adaptive message retransmission

A communication system provides for a handoff of a hybrid mobile station (MS) between a legacy network implementing a non-high rate packet data (non-HRPD) communication technology and a network implementing a high rate packet data (HRPD) communication technology. In one embodiment, the legacy network receives a handoff trigger and redirects the MS to the HRPD network. In other embodiments, the legacy network (or HRPD network) receives a handoff trigger, obtains an allocation of HRPD network (or non-HRPD network) resources from the HRPD network (or non-HRPD network), and informs the MS of the allocated HRPD network (or non-HRPD network) resources. Subsequent to the establishment by the HRPD network (or non-HRPD network) of a traffic channel with the MS, the non-HRPD network (or HRPD network) releases non-HRPD network (or HRPD network) RF resources associated with the MS. In still other embodiments, the handoffs may be controlled by a Mobile Switching Center.

Method and system for inter-technology active handoff of a hybrid communication device

A method () of communicating data and a communication device () that communicates data. At least a first portion of the data can be encoded into at least one frame () having a first bit length, and encoding at least a second portion of the data into at least one frame () having a second bit length. The method also can include placing the at least one frame having the first bit length and the at least one frame having the second bit length into an adaptive data packet () having a fixed bit length and a fixed number of frames. The adaptive data packet can be communicated to a communication device ().

Adaptive application data packaging to improve packet efficiency in a fixed frame packet communication system

A method in wireless communication devices, for example, a cellular handset, including receiving a network control message, forcing an active packet session into a dormancy state in response to receiving the network control message, suspending a dormancy timer after receiving the network control message, and starting the dormancy timer upon completion of an event, for example, a voice pre-emption, that precipitated suspension of the active packet session.
