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.

Method of an uplink HARQ operation at an expiry of time alignment timer

A random access channel (RACH) procedure includes a mobile terminal receiving from a network a message that indicates a RACH preamble for the mobile terminal. The terminal transmits the RACH preamble to the network and then receives a RACH response from the network. The terminal monitors a downlink channel according to a discontinuous reception (DRX) active time for radio resource allocation information for a data transmission by the terminal. The DRX active time specifies a time until the radio resource allocation information for the data transmission is indicated.

Method and mobile terminal for performing random access

A method for receiving system information, the method includes receiving, by a mobile terminal, a first block of second system information from a base station, wherein the first block of second system information includes scheduling information related to a plurality of second blocks of second system information; determining, by the mobile terminal, on which resource the plurality of second blocks of second system information is received using the scheduling information; and receiving, by the mobile terminal, the plurality of second blocks of second system information from the base station on the determined resource.

Method for transmitting and receiving system information via a broadcast channel (BCH) and a downlink shared channel (DL_SCH)

Disclosed is a radio (wireless) communication system providing a radio communication service and a terminal, and more particularly, to a method of delivering a continuously and/or consecutively received Packet Data Convergence Protocol (PDCP) Service Data units (SDUs) to an upper layer immediately if a PDCP entity receives the PDCP SDUs during a process of a RLC re-establishment within an Evolved Universal Mobile Telecommunications System (E-UMTS) that has evolved from a Universal Mobile Telecommunications System (UMTS) or a Long Term Evolution (LTE) system.

Method of delivering a PDCP data unit to an upper layer

A random access procedure between a mobile terminal and a network is performed based upon the characteristics of a RACH preamble transmitted by the terminal. A first type of random access preamble is selectable by the terminal from a set of random access preambles, and a second type of random access preamble is directly allocated to the terminal by the network. The network responds with a random access response. The terminal performs a discontinuous reception (DRX) operation that allows it to monitor a downlink control channel discontinuously. The DRX operation includes an active time period during which the terminal monitors the control channel after successful reception of the random access response for the second type of random access preamble until a transmission from the network addressed to a Cell-Radio Network Temporary Identifier (C-RNTI) associated with the terminal is received.

An electronic device is provided. The electronic device includes a display including a touch panel; a processor electrically connected to the display; and a memory electrically connected with the processor, wherein the memory stores instructions executed to enable the processor to: receive, from the touch panel, first data regarding a time or an area contacted by an external object through a first region on the display, receive, from the touch panel, second data regarding a contact or an approach of the external object to a second region of the display after the external object is spaced apart from the display, and display an image or an image variation on the display based on the first data or the second data.

Electronic device and input method of electronic device

An apparatus and method for performing procedures (protocols) of a PDCP (Packet Data Convergence Protocol) layer and an RLC (radio layer in an E-UMTS (Evolved Universal Mobile Telecommunications System) which has evolved from UMTS, among radio protocols of a mobile communication system. The PDCP layer performs ciphering on data (i.e., PDCP SDU) received from an upper layer, generates an indicator discriminating ciphered data and non-ciphered data (i.e., an ROHC feedback packet directly generated by the PDCP layer), and transmits the same to a lower layer (i.e., MAC layer). A PDCP SN (Sequence Number) is defined as an algorithm for ciphering the data in the PDCP layer to perform ciphering in the PDCP layer.
