Abstract:
Disclosed is the radio (wireless) communication system providing a radio communication service and the terminal, and more particularly, to a method of transmitting an aggregated measurement report to a network in an Evolved Universal Mobile Telecommunications System (E-UMTS) evolved from the Universal Mobile Telecommunications System (UMTS) or a Long Term Evolution (LTE) system.
Abstract:
The present invention relates to a wireless communication system and user equipment providing wireless communication services, and a method of transmitting and receiving data between a terminal and a base station in an evolved Universal Mobile Telecommunications System (UMTS) that has evolved from a Universal Mobile Telecommunications System (UMTS) or a Long Term Evolution (LTE) system, and more particularly, to a method of receiving a point-to-multipoint service data, and it may be an object of the present invention is to provide an improved method of receiving the point-to-multipoint service data in a wireless communication system in order to minimize a data loss by a reception entity.
Abstract:
In a wireless mobile communications system, a method for controlling a radio resource allocation is provided. A network transmits access control information to a terminal such that a request for the radio resource allocation which will be transmitted from the terminal can be controlled. The terminal selectively transmits the request for the radio resource allocation based on the received information, thus a transmission of an unnecessary request for the radio resource can be minimized, thereby preventing a waste of the radio resource.

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.
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:
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.

Abstract:
With respect to generating and sending a MAC PDU by using the radio resources allocated to the mobile terminal, the level of priority between the buffer status report (BSR) and the established logical channels are defined such that the data of each logical channel and buffer status report can be more effectively, efficiently and quickly transmitted.
