Abstract:
A mobile communications system including a network with a source network node and a target network node that supports a handover procedure, and a mobile terminal that is allowed to access the source network node and access the target network node according to the handover procedure, in which information related to a reception status of user data is delivered between at least two among a group including the mobile terminal, the source network node, and the target network node such that the target network node may receive status information from the source network node and the target network node may receive a status report from the mobile terminal.
Abstract:
Discussed is a method of sending status information (STATUS PDU) in which a receiving side reports a data received state to a transmitting side in a mobile telecommunication system. A receiving side RLC entity considers an available radio resource to construct a status PDU fit to the size of the radio resource and then sends the constructed status PDU to a transmitting side RLC entity, thereby avoiding a deadlock situation of RLC protocols.
Abstract:
A method for receiving system information via a broadcast control channel (BCCH) to which a broadcast channel (BCH) and a downlink shared channel (DL_SCH) are mapped, the method including receiving, by a user equipment (UE), a block of first system information from a base station via the BCH, and receiving, by the UE, a first block of second system information from the base station via the DL_SCH. The first block of second system information is scheduled with a fixed time offset. The method further includes receiving, by the UE, a plurality of second blocks of second system information from the base station via the DL_SCH.
Abstract:
A method including receiving, by a user equipment (UE), a block of first system information from a base station via the BCH, and receiving, by the UE, a first block of second system information from the base station via the DL_SCH. The first block of second system information is scheduled with a fixed time offset. The method further includes receiving, by the UE, a plurality of second blocks of second system information from the base station via the DL_SCH in accordance with scheduling information included in the first block of second system information. The first block of second system information includes the scheduling information, value tag information, and cell access related information. The cell access related information includes at least one of Public Land Mobile Network (PLMN) identity information, tracking area information, and cell barred information. A specific control channel indicates frequency and time information.
Abstract:
A method of performing a random access channel (RACH) procedure between a mobile terminal and a network includes the steps of detecting whether a random access response (RAR) is received from the network within a certain time period, the RAR including information about a random access channel (RACH) preamble transmitted to the network; and if the RAR is not received within the certain time period or if the information about the transmitted RACH preamble included in the RAR does not match the transmitted RACH preamble, performing a first procedure to detect failures in the RACH procedure; and if the RAR is received within the certain time period and if the information about the transmitted RACH preamble included in the RAR matches the transmitted RACH preamble, performing a second procedure to detect failures in the RACH procedure.
Abstract:
A device and method for receiving, by a mobile terminal, system information from a base station. The method includes: receiving a block of first system information from the base station via a broadcast channel configured to broadcast only system information; and receiving a plurality of blocks of second system information from the base station via a downlink shared channel configured to carry system information and other data, one of the plurality of blocks of second system information including scheduling information.
Abstract:
A method and device for receiving a warning message in a mobile communication system. The method includes receiving a paging message from a network. The paging message is used to inform the terminal about a presence of the warning message. The paging message includes a warning message indication indicating that there will be a transmission of the warning message through a downlink channel. The method includes after receiving the paging message, receiving system information in a system information block (SIB) through a control channel. The system information includes scheduling information for the warning message. The method includes receiving the warning message through the downlink channel according to the scheduling information. The warning message is an Earthquake and Tsunami Warning System (ETWS) message.
Abstract:
A method for transmitting downlink data to a mobile terminal is disclosed. The mobile terminal receives a particular common H-RNTI (HS-DSCH Radio Network Identifier) via an HS-SCCH (High Speed-Shared Control Channel) associated with an HS-DSCH (High Speed-Downlink Shared Channel), recognizes whether a header of a MAC (Medium Access Control) PDU (Packet Data Unit) transmitted by the HS-DSCH includes a terminal-exclusive identifier, acquires the terminal-exclusive identifier, and processes the MAC PDU as its own if the acquired terminal-exclusive identifier is intended for the terminal itself.
Abstract:
A method of sending status information (STATUS PDU) in which a receiving side reports a data received state to a transmitting side in a mobile telecommunication system. A receiving side radio link control (RLC) entity considers an available radio resource to construct a status PDU fit to a size of the available radio resource and then sends the constructed status PDU to a transmitting side RLC entity, thereby avoiding a deadlock situation of RLC protocols.
Abstract:
Disclosed is the radio (wireless) communication system providing a radio communication service and the terminal, and more particularly, to a method of an uplink HARQ (Hybrid Automatic Repeat reQuest) operation at an expiry of time alignment timer in an Evolved Universal Mobile Telecommunications System (E-UMTS) evolved from the Universal Mobile Telecommunications System (UMTS) or a Long Term Evolution (LTE) system.
