20110158168 | SIGNAL INTERFERENCE HANDLING METHOD AND SYSTEM AND APPARATUS USING THE SAME - A signal interference handling method adapted to a cellular system, and a system and an apparatuses using the same are provided, where the cellar system includes a macro/micro cell base station (MBS), a home base station (HBS), and a MBS-served mobile station (m-MS), and the signal interference handling method includes steps. The m-MS detects whether there is mutual interference. The m-MS sends an interference mitigation (IM) request to the HBS if there is mutual interference. The HBS enters a low duty mode (LDM) after the HBS receives the IM request. | 06-30-2011 |
20120063305 | PRIORITIZED RANDOM ACCESS METHOD - Prioritized random access methods are proposed. According to an embodiment, random access attempts are classified into the priority levels according to delay requirements, and adedicated random access opportunities are reserved for different priority levels. A congestion detecting mechanism is introduced for such dedicated ranging (random access) opportunities. When congestion is detected by the base station, parameters or configurations of random access can be dynamically or temporarily modified through random access response message. Furthermore, a prioritized contention resolution is introduced to guarantee a high priority access is processed earlier than a low priority access. According to another embodiment, another prioritized contention resolution is introduced to reduce the impact of random access of a low priority M2M device upon H2H traffic. | 03-15-2012 |
20130039309 | METHOD FOR RENEWING INDICATION OF SYSTEM INFORMATION AND BASE STATION AND USER EQUIPMENT USING THE SAME - A method for a method for renewing indication of system information, a base station using the same, a user equipment (UE) using the same, and a wireless communication system using the same is described. This disclosure proposes that renewing indication of system information and updating system information are not based on the traditional SIB (system information block) update and acquisition mechanisms. For the example of a random access (RA) procedure under extended access barring (EAB), an eNB could update EAB parameters at the time when the EAB SIB exists. Besides, a MTC (machine-type communication) device always assumes that the EAB is disabled & transmits preamble for RA directly. When the preamble is received by the eNB, the eNB notices the MTC device whether the EAB had been enabled or not. If EAB had been enabled, the MTC device interrupts current RA procedure, reads EAB SIB, and then performs EAB. | 02-14-2013 |
20130115913 | METHOD AND APPARATUS FOR NOTIFYING ACCESS CONTROL INFORMATION - A method and an apparatus for notifying activations of extended access barring (EAB) and updates of EAB information in the field of Long Term Evolution (LTE) wireless communication systems have been proposed. In accordance with the present disclosure, the eNB notifies MTC devices of EAB changes from a paging message through the paging channel (PCH). The network could use either a single bit EAB status indicator to notify whether the EAB has been enabled or disabled or use multiple bits EAB indicator to represent different EAB parameter changes in addition to whether the EAB has been enabled or disabled. Based on the present disclosure, the network could reduce the paging overhead by require the MTC device to acquire the EAB-SIB only when it needs the EAB information. | 05-09-2013 |
20140198707 | DATA TRANSMISSION METHOD THROUGH POINT TO MULTI-POINT TRANSMISSION SERVICE - The present disclosure proposes a data transmission method through multimedia broadcast multicast services (MBMS). Specifically, the present disclosure proposes using a cell broadcast service to perform data transmission, and the proposed functions would include receiving an information of a service data, allocating a data channel resource based on the information of the service data to generate an allocation information for the data channel, allocating a control channel resource based on the information of the service data to generate an allocation information for the control channel, and transmitting the allocation information for the control channel to a target device. | 07-17-2014 |
20140219198 | METHOD FOR SWITCHING COMMUNICATION CONNECTION MODE, COMMUNICATION SYSTEM, BASE STATION, TRANSMITTER AND RECEIVER - A method for switching communication connection modes, a communication system, a base station, a transmitter and a receiver are provided. The method includes the following steps. Firstly, when a base station or a core network entity determines that a communication mode between a transmitter and a receiver should be switched from a cellular communication mode to a device-to-device communication mode, the base station sends a control message to the transmitter. Next, the transmitter stops transmitting at least one first packet to the base station in response to the control message. Afterwards, the receiver receives at least one transmission-unfinished packet and a transmission-unfinished packet status related to the at least one transmission-unfinished packet forwarded by the base station. | 08-07-2014 |
