摘要:
A method and corresponding apparatus for performing minimization of drive tests (MDT) in a mobile communication system are provided. The method may include receiving, by a base station, a control message from a user equipment (UE). The control message may be one of a MDT prohibit indication configured to indicate the base station should not select the UE for performing MDT, a UE status indication including at least one first UE parameter to be used by the base station when selecting MDT UEs, and a MDT measurement rejection when at least one second UE parameter differs from a predetermined UE parameter threshold.

A method of transmitting a control signal in a wireless communication system includes transmitting a control signal on an uplink channel, determining whether an unrecoverable error, which cannot be corrected in a specific layer, is detected during the transmission of the control signal and if the unrecoverable error is detected, transmitting a message which informs that the unrecoverable error is detected. A deadlock due to an unrecoverable error in the specific layer can be prevented.
摘要:
A method for performing random access in a wireless communication system is provided. The method includes transmitting a preamble for random access in uplink, receiving a random access response message including back-off information as a response to the preamble, and performing back-off using the back-off information when the random access has failed.
摘要:
A method of receiving a message by a relay node in a mobile communication system is disclosed. The present invention includes receiving control information including a first group identifier on a backhaul subframe, and receiving the message based on the control information if the received first group identifier indicates the relay node, wherein the message includes a second group identifier, the second group identifier being corresponded to the first group identifier.

A method of allocating radio resources in a wireless communication system is disclosed. A method of allocating radio resources from a network of a wireless communication system in accordance with a plurality of scheduling modes comprises transmitting first scheduling information to a user equipment to allocate radio resources to the user equipment in accordance with a first scheduling mode, the first scheduling information including a first user equipment identifier, and transmitting second scheduling information to the user equipment to allocate radio resources to the user equipment in accordance with a second scheduling mode, the second scheduling information including a second user equipment identifier.
摘要:
A method and apparatus of triggering a status report in a wireless communication system is provided. A duplicated data block is received. A triggering of a status report is suspended if the duplicated data block requests the status report and a sequence number (SN) of the duplicated data block is equal to or greater than a maximum status transmit state variable. Even if a duplicated data block requests a status report, the status report is triggered after hybrid automatic repeat request (HARQ) reordering is complete.
摘要:
A method of handling a radio link failure in a multiple-carrier system performed by a user equipment (UE) is provided. The method includes transmitting, to a base station (BS), a first message indicating a first radio link problem (RLP) in a first carrier when the first RLP is detected, transmitting, to the BS, a second message indicating a second RLP in a second carrier when the second RLP is detected, and transmitting, to the BS, a final message requesting a connection re-establishment with the BS. By using a plurality of different timers on CCs configured for one UE, the meaning of RLF in a multiple-carrier system for triggering radio connection re-establishment procedure is clarified and defined in detail.
摘要:
A HARQ processing method is disclosed, by which a measurement gap is considered. In particular, as a terminal performs an inter-measurement operation, if HARQ feedback information reception is impossible, the terminal determines HARQ feedback information, which is not received for a next HARQ operation, as ACK or NACK by itself and is then able to perform the next HARQ operation. Specifically, in case that the terminal operates by determining the non-received HARQ feedback information as ACK, a corresponding uplink signal keeps being stored in an HARQ buffer and can be retransmitted according to a new UL grant reception from a base station.
摘要:
A method of reporting of channel quality in a wireless communication system is disclosed. A method of reporting of channel quality in a user equipment, which receives a point-to-multipoint service in a wireless communication system, comprises receiving configuration information for reporting of channel quality from a network, the configuration information corresponding to each of at least one uplink channel, receiving a request message requesting the channel quality from the network, and reporting the channel quality using configuration information corresponding to an uplink channel among the at least one uplink channel.
摘要:
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.
