Abstract:
A method of efficiently processing a random access response message, when a terminal (or user equipment) performs random access, is disclosed. After the terminal transmits a random access preamble to a base station, the terminal may receive a random access response message having a format of medium access control protocol data unit (MAC PDU) including only a backoff indicator subheader in a MAC header of the MAC PDU, from the base station in response to the random access preamble. As described above, the terminal, which has received the random access response message including only a backoff indicator subheader in the MAC header of the MAC PDU, may consider a random access response reception procedure not successful and may perform a subsequent procedure for a random access responses reception failure.
Abstract:
Disclosed are methods for prompt re-direction of uplink access of a specific user equipment and controlling random access. Specifically, for initial random access to a network, if a user equipment (UE) transmits a preamble (S201), which includes information related to random access, to a network node, the network node sends grant/rejection information of the preamble and re-direction information as a response message to the preamble (S203) to the UE.
Abstract:
A method of transmitting and receiving radio resource information is disclosed, by which a mobile terminal is able to quickly access a mobile communication system. The present invention includes transmitting a paging message to locate a specific mobile terminal by including information for a radio resource allocated to the mobile terminal in the paging message receiving a response signal for the paging message transmitted according to the information for the radio resource, and performing a connection to the mobile terminal according to the response signal.
Abstract:
A method of processing control information in a mobile communication system is disclosed, by which an RRC connection setup can be quickly completed and by which control information can be processed without an unnecessary standby of a mobile terminal. The present invention includes the steps of receiving a plurality of protocol data units transmitted plural time from a transmitting side via one common logical channel by an RLC (radio link control) entity operating in a UM (unacknowledged mode) and having a receiving window and a timer, re-ordering a plurality of the received protocol data units using sequence numbers of a plurality of the received protocol data units, the receiving window and the timer, reassembling at least one service data unit by processing a plurality of the re-ordered protocol data units, and delivering the at least one service data unit.
Abstract:
A method and apparatus for reporting location information are provided. A wireless device transmits a Packet Data Convergence Protocol (PDCP) control Protocol Data Unit (PDU) to a base station. The PDCP control PDU includes a D(Data)/C(Control) field indicating a control PDU, a PDU type field indicating location information and the location information of the wireless device.
Abstract:
A method for logging measurement results in a wireless communication system is provided. The method includes: receiving a logged measurement configuration from a network, the logged measurement configuration comprising information for performing logged Minimization Driving Test (MDT); measuring at least one cell based on the logged measurement configuration; determining whether the measurement result has importance for logging; if a storage space for logging is enough for additionally logging, setting an importance tag of the measurement result to a predetermined value in accordance with the determination; and logging the measurement result and the importance tag in the storage space.
Abstract:
Provided is a method for processing location information performed by a network node in a wireless communication system. The method comprises acquiring location information on a terminal, acquiring a log identifier for identifying a logged measurement relating to the location information on the terminal, determining the type of location information, and transmitting, if the location information is a first type, the location information of the first type and the log identifier to a location information calculating node.
Abstract:
Disclosed is a method for generating a data block to be transmitted from a specific layer in a transmitting side to a receiving side in a wireless communication system. The method includes receiving an upper layer datei block from an upper layer and generating a lower layer data block including at least part of the upper layer data block and state indication information indicating a state of the upper layer data block, the state indication information being selected variably according to a logical channel through which the upper layer data block is received. This method optimizes overhead of a header of each upper layer data block according to contents of the upper layer data block and event situations associated with the upper layer data block, thereby increasing system efficiency.
Abstract:
A method of a cell reselection performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving supreme priority information from a target cell, the supreme priority information indicating whether a deprioritization is applied; applying the supreme priority information, if the supreme priority information indicates that the deprioritization is applied; and performing a cell reselection based on the applied deprioritization.
Abstract:
In an aspect, a method of communication performed by a user equipment (UE) camping on a long term evolution (LTE) cell in a wireless communication system is provided. The method include: receiving a Circuit Switched fallback (CSFB) control message from a network, the CSFB control message comprising prioritization information for CS service; determining whether the CS service is triggered; if it is determined that the CS service is triggered, applying a priority to frequencies of at least one cell in accordance with the priority information; performing a mobility procedure based on the applied priority; performing a Radio Resource Control (RRC) connection establishment procedure with a selected inter-RAT cell; and initiating the CS service.
