At each retransmission mthe receiver thus acquires extra information, and the probability of correct de-coding increases. Depending on the radio bearer, the main functions of the PDCP layer are header compression, security integrity protection and cipheringand support for reordering and retransmission during handover. SFN identifies the 10 ms radio frames of a cell of an eNodeB. A channel carrying data traffic. A transport layer protocol used along with the Internet Protocol IP.
It can provide connection authentication, as well as offering transmission encryption and compression. A unit of transmission resource consisting of 12 subcarriers in the frequency domain and 1 timeslot 0. A label attached to a packet to indicate the order in which the packet was transmitted with respect to other packets. Implementation eXtra Information for Testing. UDP assumes that error checking and correction is either not necessary or performed in the application.
The entity in a radio access network responsible for radio trans- mission and reception in one or more cells to and from the UE.

The length of the CRC determines the number of errors which ts42.008 be detected in the block of data on reception. Next Generation Mobile Networks. Channel State Information at the Transmitter. It is included in the LTE X2 setup procedure.
All algorithms use a bit input key. QPSK is a modulation scheme in which information is conveyed through phase variations of a carrier, while keeping a constant amplitude and frequency. UDP is not designed to support reliable transfer, and therefore packets may arrive out of order, be duplicated, or be lost without notice.
Dynamic parts such as the timestamp in the RTP header are compressed by transmitting only the difference from a reference maintained in both the transmitter and the receiver.
A mode of bidirectional communication in which trans- missions in each direction take place on the same carrier frequency but in different time slots. It provides a measure of the uplink load level in a cell. Signal to Interference Ratio. It is a stochastic way of implementing the steepest descent method. For each mobile station, the SGSN stores subscription and location information, including the cell or the Routing Area RA where the mobile station is registered.
In LTE the UE has to be able to perform cell search without an explicit neighbour cell list being provided.
The joint standardization partner-ship responsible for standardizing CDMA and its derivatives. The details will be finalized in a later release of LTE.
Specifies additional spectral emission constraints for particular deployment scenarios. The LTE uplink physical channel carrying scheduled data traffic, and control signalling if some is required to be transmitted in the same subframe. The connection to the physical layer below is through transport channels, and the connection to the RLC layer above is through logical channels.
Typically the mobile network run by one net- work operator in one country. It consists of three digits. In LTE, turbo codes were instead selected as the channel coding technique.
It is a bit integer. A filter shape, frequently used for pulse-shaping because of its ability to minimize Inter-Symbol Interference ISI when used at both the transmitter and receiver — the two 3gppp together having a Raised Cosine response.
This may include emergency public warnings.
Policy and Charging Enforcement Function. A network node that acts as a gateway between 3g;p GPRS wireless data network and other networks. The frequency response of an RRC filter is a piecewise function equal to unity in the centre frequencies and approaching zero following the square-root of a raised cosine curve. The MPR is non-zero only for particular combinations of system bandwidth, transmit bandwidth con- figuration resource blocks allocations and modulation scheme which make it difficult to control sufficiently the adjacent channel leakage.

Additional Spectrum Emission Mask. Provides a mechanism to limit signalling during inter- Radio Access Technology inter-RAT cell reselection in idle mode. Physical Downlink Control CHannel. Frequency Domain Spectral Shaping. An LTE measurement which provides a cell-specific signal strength metric.

This allows the network operator or service provider to regulate access by the subscribers to services, by the barring of certain categories of outgoing or incoming calls or of roaming. Transmission Gap Repetition Period. In addition it can handle multiple streams and is tolerant of network-level faults through support of multi-homing. The procedure by which the UE updates the network as to its new location, either periodically or whenever it moves out of its current Tracking Area TA. A logical communication link between a UE and an eNodeB, carrying one or several radio bearers.
Voice over Internet Protocol. A data link protocol used to establish a direct connection between two networking nodes.
