| 20100330998 | METHOD OF TRANSMITTING AND RECEIVING RADIO ACCESS INFORMATION IN A WIRELESS MOBILE COMMUNICATIONS SYSTEM - In a wireless mobile communications system, a method of transmitting and receiving radio access information that allows a faster and an efficient way of establishing a radio connection between a terminal and a target base station while performing a handover for the terminal to a cell of the target base station. The network transmits in advance, the radio access information and the like, to the terminal so that the terminal can be connected with the target cell in a faster manner which minimizes the total time for the handover process. | 12-30-2010 |
| 20110026511 | METHOD OF PROCESSING DATA IN A MEDIUM ACCESS CONTROL (MAC) LAYER - A method of processing data in a Medium Access Control (MAC) layer through which at least one first channel is mapped to a second channel in a transmitting end of a wireless communication system is disclosed. More specifically, a MAC layer data block is configured by including at least one higher layer data block received through the at least one first channel and adding a header thereto which includes at least one field which indicates at least two types of information. Furthermore, the MAC layer data block is transferred to a lower layer through the second channel. | 02-03-2011 |
| 20110032891 | METHOD FOR TRANSMITTING RESPONSE INFORMATION IN MOBILE COMMUNICATIONS SYSTEM - A method for transmitting radio resources in a mobile communication system is disclosed. The method includes receiving a random access channel (RACH) preamble from a plurality of UEs and transmitting response information associated with the received preambles over a common channel wherein the plurality UEs can access the common channel and receive corresponding information. If a HARQ scheme is used when a UE transmits data to the eNode-B using uplink radio resources allocated over the RACH, the eNode-B does not pre-allocate uplink radio resources required for re-transmission and performs allocation of radio resources for a first transmission of HARQ. If the re-transmission is required, the eNode-B allocates the radio resources required for the re-transmission with the NACK signal. If re-transmission is not required, the present invention can reduce an amount of wasted radio resources. | 02-10-2011 |
| 20110080861 | MBMS DUAL RECEIVER - A method for communicating between a network and a dual receiver UE includes receiving first signaling from a first network node at a first frequency, and receiving second signaling via a PtM control channel from a second network node at a second frequency. The method further includes receiving a request from the second network node at the second frequency, such that the request is carried on the PtM control channel, and transmitting to the first network node a response to the request from the second network node. An alternative method includes receiving communications from a first network node, and identifying that the first network node lacks uplink capabilities. This method may further include identifying that the first network node provides a MBMS service, and receiving the MBMS service from the first network node despite the identification of the lack of uplink capabilities. | 04-07-2011 |
| 20110105107 | APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING ACTIVATION INDICATOR REGARDING COMPONENT CARRIER IN WIRELESS COMMUNICATION SYSTEM - A method for supporting activation/deactivation of serving cells by a base station (eNB) in a wireless communication system provides decreased overhead and decreased power consumption for a user equipment (UE). The method includes configuring M supportable serving cells in the UE, configuring an indicator indicating activation/deactivation of each of the M serving cells, configuring a medium access control (MAC) message which includes a MAC control element (CE) and a logical channel identifier (LCID), the MAC CE including the indicator configured for each of the M serving cells and having a length corresponding to an integer multiple of 8 bits, the LCID indicating that the MAC CE includes the indicator indicating activation/deactivation of each serving cell, and transmitting the configured MAC message to the UE. Accordingly, a control channel or data channel regarding a component carrier is selectively received depending on whether the component carrier is activated. | 05-05-2011 |
| 20110117919 | METHOD OF COMMUNICATING SIGNALS IN A MOBILE COMMUNICATION SYSTEM - A method of communicating signals in a mobile communication system having a first base station, a second base station, and a base station controlling node controlling the first base station and the second base station is presented. The method includes during a handover, receiving, at the first base station, a control message from the second base station including a sequence number indicating at least one data unit to be transmitted to a mobile station or to be received from a mobile station, wherein the first base station receives the control message from the second base station without being controlled by the base station controlling node. | 05-19-2011 |
| 20110164540 | METHOD AND APPARATUS FOR RECONFIGURING A COMMON CHANNEL - The present invention for reconfiguring a common channel receives modified channel configuration information of a first common channel through a second common channel, and determines a starting time of reconfiguring the first common channel, according to a type of an information element including the modified channel configuration information. Also, the present invention reconfigures the first common channel from the determined starting time. According the present invention, the common channel, such as the MCCH, may be reconfigured more efficiently. | 07-07-2011 |
