20080214178 | Method for Optimizing Receipt Notification Information Interchange in Synchronous Communication Between Terminal and Network and Mobile Terminal - To optimize the interchange of an ACK signal and a NACK signal between a terminal and a network and reduce the conflict on the terminal level. The invention relates to a method for optimizing the interchange of a receipt notification signal between a plurality of base stations and a mobile terminal synchronously connected in a cellular communication network. The method comprises a step of estimating the quality of down-link between each base station and the terminal on at least one standardized transmission channel, and a step of retransmitting data to the base station depending on the estimated quality of link. | 09-04-2008 |
20090061880 | Method for Optimizing Exchanges of Information on Acknowledgement in Asynchronous Communication Between Terminal and Network - In a method for optimizing exchanges of acknowledgement signals between a mobile equipment in asynchronous communication with a plurality of base stations of a cellular telecommunication network, the terminal sends data to the base stations and each base station is likely to return to the terminal a positive acknowledgement ACK or negative acknowledgement NACK. The method includes the steps of: synchronizing the mobile equipment with the network; and estimating quality of downlink communication between each base station and the mobile equipment on at least one standardized channel, such that if at least one base station returns an acknowledgement to the mobile equipment, the mobile equipment only requests a NACK from the base stations whilst the data is continuously being transmitted, and if all the base stations return a NACK to the mobile equipment, the mobile equipment only requests an ACK from the base stations during the current communication. | 03-05-2009 |

A method of a radio resource in a mobile communication network, including steps of: determining a ratio of terminals that desire reception of MBMS service; transmitting a signal for requesting terminals to indicate that these terminals do not support HSDPA service but support DCH service to a network in the case that the determined ratio is not more than a predetermined threshold value; and allocating a resource, which is necessary for effective simultaneous reception of MBMS service, a packet switch service (PS), and a circuit switch service (CS), to terminals. | 10-29-2009 |
20100279697 | Determination of a Network Parameter - A method of determining a network parameter in a telecommunication system is disclosed. The system has a coverage area including at least two sub-areas, and also includes a User Equipment (UE) being in idle mode and being registered in at least two of these sub-areas. According to the present disclosure, a network node in the system receives from the UE a time information relating to the time periods the UE has been present in each of the at least two sub-areas it is registered in, respectively, and then this time information is utilized to determine a network parameter in the system. | 11-04-2010 |

20120020231 | Method for wireless communication in a device with co-existence radio - Various methods for wireless communication in a device with co-existed/co-located radios are provided. Multiple communication radio transceivers are co-existed/co-located in a user equipment (UE) having in-device coexistence (IDC) capability, which may result in IDC interference. For example, the UE is equipped with both LTE radio and some ISM band applications such as WiFi and Bluetooth modules. In a first method, the network identifies IDC capability by UE identification (e.g., UE ID). In a second method, the UE intentionally performs cell selection or reselection to cells in non-ISM frequency bands. In a third method, the UE signals the existence of ISM band applications via capability negotiation. In a fourth method, the UE signals the activation of ISM band applications by signaling messages (e.g., RRC message or MAC CE). Under the various methods, the UE and its serving eNB can apply FDM or TDM solutions to mitigate the IDC interference. | 01-26-2012 |

In a third embodiment, the LTE radio module changes its power or power class and explicitly informs the eNB through UE capability or new RRC message or MAC CE. Power control can be used as a low cost and lightweight solution before applying other heavyweight solutions that either require more resource or control overhead, or have higher impact on throughput. | 07-12-2012 |
