The embodiments of the invention provide at least a method and apparatus to schedule an uplink communication from a user equipment of a plurality of user equipment; identify one or more candidate cells to support the uplink communication from the user equipment; send a request to the identified one or more candidate cells for requesting at least one of antenna data and pilot symbols from the one or more candidate cells for the uplink communication from the user equipment; and in response to the request, receive the uplink communication from the user equipment via a coordinated multi-point operation using at least in part a reception cells of the one or more candidate cells. Further, to receive, by one or more candidate cell, from a serving cell a request for at least one of antenna data and pilot symbols from the one or more candidate cells for a scheduled uplink communication from a user equipment to the serving cell; and in response to the request, provide the at least one of antenna data and pilot symbols for the uplink communication from a user equipment to the serving cell.

Management of coordinated multi-point communication

A method at a user equipment in an LTE system includes selecting one of a number of CDMA systems, and signaling indication(s) of the selected CDMA system to a network element. The network element receives indication(s) of CDMA system(s), which correspond to requested action(s) by a UE. The network element routes information corresponding to the requested action(s) to the CDMA system(s). Another network element in the LTE system signals to the UE indications of a mapping of a number of CDMA systems to associated ones of LTE system(s). The other network element receives signaling from the UE including indication(s) of selected CDMA system(s) selected by the UE.

Enabling CDMA2000 system sharing in LTE

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 a clear channel link for transport of encrypted payload across a network of the communication system. When a source access network receives, via an air interface, a frame that is formatted pursuant to an air interface protocol and that comprises encrypted payload, the source access network demultiplexes the frame to separate the encrypted payload and assembles an Intersystem Link Protocol (ISLP) frame that comprises the encrypted payload. The source access network adds a link layer header to the ISLP frame that identifies one or more of frame type information and a sequence value associated with the frame and conveys the ISLP frame and added header across the network, for example, to a destination access network. Based on the added header, the source and destination access networks are able to perform clear channel synchronization.

Method and apparatus for end-to-end clear transport protocol

Apparatus and method for performing radio environment reporting on a reverse common signaling channel. When a dedicated RF connection between a remote unit (RU) () and infrastructure equipment () is being released, the RU receives a first message from the infrastructure instructing the RU to perform occasional pilot strength reporting on the reverse common signaling channel (r-csch) while the RU is in the idle state. In the preferred embodiment, the pilot strength reporting is limited by a maximum number of reports and/or a time limit to preserve battery life and prevent r-csch congestion in the system. Preferably, a Radio Environment Report Message, referred to generally herein as a second message, carries radio environment information (REI), such as pilot strength and phase of the best pilots measured, and helps the infrastructure both with tracking the RU location and with selecting a strong set of pilots for channel assignment.

Apparatus and method for performing radio environment reporting on a reverse common signaling channel

An apparatus and method for optimizing the transition of a Mobile Station (MS) between states of operation for packet data service. An RF connection is established between the MS and Base Site Equipment (BS) for the transmission of data packets. After a period of inactivity of transmission, the RF connection is released and the BS provides the MS with the equipment identifier of the network element that will maintain the connection with a PDSN. The MS retains the identifier while in the Dormant state and a new Semi-Dormant state and sends the identifier to the BS when requesting reactivation. In the Dormant state, the network element maintaining the connection to the PDSN is the PCF. In the Semi-Dormant state, the network element maintains the connection between to the PDSN is the SDU. When the BS has data to transmit to a MS in the Semi-Dormant state, it channel assigns the MS into the Active state according to pilots reported in RF Measurement Report Messages previously received from the MS.

Method for expediting transitions between states of operation in communications equipment

Method and apparatus for toggling service options after completion of call setup, is disclosed for use in a wireless communication system. A service option preferred by the base station ( ) or other portion of the system infrastructure is compared to service option capabilities of the mobile station ( ) requesting service. If the mobile station ( ) is capable of accommodating the service option preferred by the base station ( ), a service connect message ( ) is sent to the mobile station ( ) to initiate toggling of the service option.

Mobile communication system with improved base station control

The method for reducing status reporting in a wireless communication system (100), such as a code division multiple access wireless communication system is described. Wireless communication system (100) includes a mobile switching center (202), a base station controller (204), and a plurality of base transceiver stations (240-242). The method includes wireless communication system (100) receiving a mobile communication signal (115) from a mobile station (220), and based on the mobile communication signal (115), invoking delivery of an information element (230) to base station controller (204). The method further includes, based on information element (230), selectively forwarding by base station controller (204) a status message to mobile switching center (202). In addition, the method includes acknowledging, by base station controller (204), successful receipt of information element (230).
