Method for transmitting status report of pdcp layer in mobile telecommunications system and receiver of mobile telecommunications

A status report transmission of the pdcp layer for a pdcp status report can reduce radio resources by transmitting the reception success or failure of a series of pdcp service data units (sdus) in the form of a bitmap when configuring the pdcp status report for reporting a reception status of pdcp sdus to another party in the pdcp layer. A pdcp control packet data unit (pdu) is generated to communicate a status report for one or more pdcp sdus transmitted from a transmitting node. ... Optis Cellular Technology Llc

Method and mobile terminal for performing random access

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. ...

Method and arrangements in a telecommunication system for handling status information of data units

A method is provided in a receiving node for handling status information of data units transmitted from a sending node to the receiving node over a radio link. The receiving node establishes that a number of data units that has been transmitted by the sending node are missing. ... Optis Cellular Technology Llc

Decoding control information received over a control channel

A user equipment (ue) receives a physical downlink control channel (pdcch) at subframe k and decodes at the subframe k a set of pdcch candidates including l control channel elements (cces). The l cces are contiguously located from a position given by using a variable of yk and a modulo (n/l) operation, where n represents a total number of cces in the subframe k, yk is defined by yk=(a*yk−1)mod d, and a and d are predetermined constant values. ...
