The eNodeBs can be interconnected with each other by means of the X2 interface. Received Signal Code Power. Public Safety Answering Point. This gives more ts24.008 diversity than a set of contiguous subcarriers. QoS guarantees are especially important for real-time streaming applications, such as Voice over Internet Protocol VoIPsince these are often delay-sensitive. A scheme allowing multiple users to access a given radio channel by the use of CDM to multiplex the data fs24.008 of the different users.

Any change to a 3GPP specification v3.

Online 2G/GSM, 3G/UMTS, 4G/LTE Message Analyser

Therefore multiple SAW processes can be interlaced in time so that all the transmission resources can be used by one of the processes. These are therefore called quadrature carriers, from which the scheme derives its name. Message Authentication Code for Integrity. A CS connection reserves dedicated transmission resources for data transfer at a fixed ts240.08 for the duration of the communication session. QPSK is a modulation scheme in which information is conveyed through phase variations of a carrier, while keeping a constant amplitude and frequency.

In LTE, turbo codes were instead selected as the channel coding technique. It defines the means of transmittting raw bits rather than logical data packets over a physical link. The frequency response of an RRC filter is a piecewise function equal to unity in the centre frequencies and approaching zero following ts224.008 square-root of a raised cosine curve.

An upper bound on packet delay which needs to be satisfied when the UE has sufficient radio channel quality. This allows the network operator or service provider 3gppp regulate access by the subscribers to services, by the barring of certain categories of outgoing or incoming calls or of roaming.


It supports functions related to bearer and connection management. The ratio between the power of the Radio Frequency RF carrier bearing the wanted signal and the total power of interfering signals. The PCO may include the address allocation preference indicating that the UE prefers to obtain an IPv4 address only after the default bearer activation.

HO is a procedure by which a mobile terminal changes serving cells within the same frequency or on different frequencies or even on different Radio Access Technologies RAT. It enables the UE to form the correct phase reference for demodulating the PDSCH data, based on the correct linear combination of the common reference signals. A downlink transport channel used to transport paging information to UEs.

3gp radio link in the direction from the mobile to the base station. ACS is predominantly defined by the ratio of the receive filter attenuation on the assigned channel frequency to the receive filter attenuation on the adjacent channel.

Reference Signal Received Quality. Time Division Multiple Access.

For an information block size Ka QPP interleaver is defined by a polynomial. Globally Unique Temporary Identity. A signal transmission scheme using multiple subcarriers closely-spaced in the frequency domain such that adjacent subcarriers are orthogonal to each other; such schemes enable the symbol length to be increased compared to a single-carrier transmission and are therefore typically tolerant of multipath propagation.

LTE comprises a new radio interface and radio access network architecture.

Ciphering Key Sequence Number. In LTE, a logical channel used to deliver control information in both uplink and downlink directions during connection establishment. Such a simple SAW operation cannot on its own utilize the transmission resources during the period between the first transmission and the retransmission.

A zone where the correlation between a Zadoff-Chu ZC sequence and a cyclic-ly shifted replica of the same sequence is equal tozero.


The length of the CRC determines the number of errors which can be detected in the block of data on 3glp. An indicator sent on the X2 interface between eNodeBs to indicate which resource blocks will be used for cell-edge UEs. The difference between a reference frequency and the frequency of a received Radio Frequency Tx24.008 carrier. Ts24.080 type of amplifier which aims to amplify the desired signal while adding as little noise as possible and without distorting the desired signal.

Signal distortion which results when two or more signals are present at the input of a non-linear device such as an amplifier in a receiver. It is typically used to drive the antenna of a transmitter.

3GPP Message Analyser – 2G, GSM, 3G, UMTS, 4G, LTE message decoding and encoding

A form of an optimal estimator which, when applied to an observation, outputs the hypothesis that is most likely to have caused the current observation. Usually refers to a propagation model originally developed for. It is assigned by the target eNodeB. The terminals connect to the core network via the access network which is RAT-specific. Additive White Gaussian Noise.

It also indicates the time-frequency slot of the preamble to which the RAR corresponds. UDP is not designed to support reliable transfer, and therefore packets may arrive out of order, be duplicated, or be lost without notice.

A PWS provides the ability to broadcast 3pgp to alert the public to major emergencies, such as natural and te24.008 disasters. The use of two or more physically separate antennas for reception. A type of Public Warning System that broadcasts warnings of earthquakes and tsunamis to any UE which is capable of receiving them.
