A method for transmitting an enhanced Random Access CHannel (RACH) in a User Equipment (UE) in a mobile communication system is provided, in which the UE transmits an uplink preamble to a Node B and upon receipt of an ACKnowledgment (ACK) for the uplink preamble, transmits an Enhanced Uplink Dedicated CHannel (E-DCH) and a Dedicated Physical Control CHannel (DPCCH) to the Node B. The transmission of the DPCCH starts before the transmission of the E-DCH.

A method for transmitting an enhanced Random Access CHannel (RACH) in a User Equipment (UE) in a mobile communication system is provided, in which the UE transmits an uplink preamble to a Node B and upon receipt of an ACKnowledgment (ACK) for the uplink preamble, transmits an Enhanced Uplink Dedicated CHannel (E-DCH) and a Dedicated Physical Control CHannel (DPCCH) to the Node B. The transmission of the DPCCH starts before the transmission of the E-DCH.
摘要:
An apparatus and method for transmitting a control signal using a symbol or bit pattern of an existing pilot channel, instead of using the time multiplexing method in the separate code channel or the existing physical channel, and reducing an error rate while a reception side detects the control signal are provided. For that purpose, a transmission side allocates transmission power corresponding to a pilot pattern determined according to the control information. A corresponding reception side detects control information based on a pilot pattern of pilot bits inserted in a dedicated physical channel (DPCH) and generates transmit power control (TPC) bits referring to a target reception power which is set based on the control information.

摘要:
A mobile communication system using an Enhanced Uplink Dedicated transport Channel (EUDCH) for uplink data transmission, wherein a user equipment (UE) receives cell group information from a radio network controller (RNC), and soft-combines scheduling signals or acknowledge/negative-acknowledge (ACK/NACK) signals received from cells belonging to the same cell group according to the cell group information, thereby improving detection performance.
摘要:
An MRAM device may include semiconductor structures, a common source region, a drain region, a channel region, gate structures, word line structures, MTJ structures, and bit line structures arranged on a substrate. Each of the semiconductor structures may include a first semiconductor pattern having a substantially linear shape extending in a first direction that is substantially parallel to a top surface of the substrate, and a plurality of second patterns that each extend in a third direction substantially perpendicular to the top surface of the substrate. A common source region and drain region may be formed in each of the semiconductor structures to be spaced apart from each other in the third direction, and the channel region may be arranged between the common source region and the drain region. Gate structures may be formed between adjacent second semiconductor patterns in the second direction. Word line structures may electrically connect gate structures arranged in the first direction to each other. MTJ structures may be electrically connected to corresponding ones of the second semiconductor patterns. Each bit line structure may electrically connect two adjacent MTJ structures in the first direction to each other.

A method and apparatus for uplink scheduling in a communication system are provided. The method includes determining whether a User Equipment (UE) is included in an uplink scheduling list, a buffer length of the UE is estimated, if the UE is included in the uplink scheduling list, it is determined whether a Buffer State Report (BSR) indicating the buffer length of the UE has been received from the UE, if the estimated buffer length is 0, and the UE is transitioned to a non-zero BSR reception state and maintained in the uplink scheduling list, if the BSR has not been received from the UE. The non-zero BSR reception state is a state in which a zero BSR indicating the buffer length of the UE is 0 has not been received.
摘要:
A method and apparatus for informing a plurality of terminals receiving the same Mobile Broadcast (BCAST) service of an upcoming event such as a BCAST service change in a BCAST system are provided. When receiving a notice of a notification event related to a BCAST service or an Service Guide (SG), a BCAST Subscription Management (SM), including a Notification Generation Function (NTG), creates a notification message about the notification event and sends it to a BCAST Service Distribution/Adaptation (SD/A). The BCAST SD/A sends the notification message to one terminal or a group of terminals through a Broadcast Distribution System (BDS) or an interaction network.
摘要:
A mobile terminal including a transceiver configured to transmit and receive signals to and from another mobile terminal, a security parameter module configured to set a security parameter in data to be transmitted to the another mobile terminal and to detect whether or not the security parameter is set in data received from the another mobile terminal, and a checking module configured to compare information related to the mobile terminal and the another mobile.

A method for ciphering MBMS (Multimedia Broadcast/Multicast Service) data in a wired/wireless communication system is provided. The MBMS service enables the same service or desired services to be provided to a number of users. In the ciphering method, a ciphering key for encoding MBMS data is previously provided to an authorized UE, and the authorized UE is informed of when MBMS data encoded using the ciphering key is to be transmitted, thereby preventing unauthorized UEs from illegally receiving the MBMS service.
