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 uses two transmit antennas, with the same data being transmitted from both NodeB antennas, using a space-time block code to en- sure orthogonality of the signals from the two transmit antennas. An LLR can be computed for each information bit as opposed to parity bitswhere each hypothesis corresponds to one possible value of the information bit.
A function located in the eNodeB which handles uneven distribution of the traffic load over multiple cells. A duplex scheme whereby the uplink and downlink use different frequencies but not simultaneously, so as to avoid the need for a duplex filter in the receiver. A processor which converts a sampled, quantized digital input signal into a continuous-time analogue-valued output signal.
Evolved Packet System Encryption Algorithm.
First Missing Service Data Unit. The term used to describe the control signalling e. RBC is involved in the release of radio resources associated with radio bearers, for example at session termination or handover.
3GPP Message Analyser – 2G, GSM, 3G, UMTS, 4G, LTE message decoding and encoding
The joint standardization partner-ship responsible for standardizing CDMA and its derivatives. Comprises the functions executed by the eNodeB to manage mobility and handover in both idle and connected modes. A RAU can also be performed periodically, with the time interval being set by the network.
A data link protocol used to establish a direct connection between two networking nodes. The main functions of the RLC layer are segmentation and reassembly of upper layer packets in order to adapt them to the size which can actually be transmitted over the radio interface.
In contrast with Circuit Switching CS where dedicated transmission resources are re- served between network nodes to deliver a reliable transmission rate and delay, in a PS connection the transmission rate and delay may vary depending on the traffic load and the medium capacity, with packets being buffered if necessary.
A minimum bit rate requested by an application.
Online 2G/GSM, 3G/UMTS, 4G/LTE Message Analyser
Under this condition a throughput requirement has to be met for a specified reference measure- ment ts24.08. Used in tests for audio noise arising from electromagnetic interference. Cell Radio Network Temporary Identifier. Allocation and Retention Priority. A term used in 3GPP to indicate that a topic will be discussed further, and any agreements will be based on further analysis. The ratio between the power of the Radio Frequency RF carrier bearing the wanted signal and the total power of interfering signals.
Similarly to Reference Signal Ts42.008 Power RSRPthis measurement is mainly used to rank different LTE cells according to their signal quality as an input for handover and cell reselection decisions, for example in scenarios for which RSRP measurements do not provide sufficient information to perform reliable mobility decisions. UDP assumes that error checking and correction is either not necessary or performed in the application.
A unit of transmission resource consisting of 12 sub- carriers in 3tpp frequency domain and 1 timeslot 0.
The part of the 3GPP system which is independent of the connection technology e. The RIV indicates the starting resource block of the contiguous allocation and the length of the contiguous allocation of resource blocks. Dynamic Host Configuration Protocol.
The reserved resources are not accessible to any other user. A relaxation factor taken into account in the UE Reference Sensitivity REFSENS in terms of the minimum received signal strength sufficient to satisfy a specified throughput requirement for a particular transmission configuration. Transmission Gap Repetition Period. The RAC identifies a routing area within a location area. A particular case of Orthogonal Frequency Division Multiple Access OFDMA in which each user is assigned a set of non-contiguous subcarriers, typically equally-spaced and interleaved with the sets assigned to other users.

The TGRP is the time between the start of one transmission gap and the start of the next. This zone maintains orthogonality between the two sequences provided that the misalignment between them is smaller than the shift. The largest block of Internet Protocol IP data which may be transferred using a data link connection. A logical communication link between a UE and an eNodeB, carrying one or several radio bearers. Refers to signal oscillation frequencies such that if the signal is input to an antenna an electromagnetic field is generated suitable for wireless communication.
A type of Forward Error Correction FEC code in which k input bits to be encoded are fed into a shift register with a number stages corresponding to the memory of the CC, and n output bits are taken from the shift register as a linear combination of the content of the shift register. A decoding technique where multiple data streams which are individually channel-coded and are received simultaneously, are processed one by one, from the strongest to the weakest stream.
The process by which the network decides whether or not to admit a new call. Multicast channel Subframe Allocation Pattern. An identifier used in the authentication process to enable communications with a mobile terminal to be ciphered without the continual need for reauthentication.
It corresponds to the index of the precoder within a codebook shared by the UE and eNodeB that maximizes the aggregate number of data bits which could be received across all downlink spatial transmission layers.
In general, a signal of fixed polarity i. Constant Amplitude Zero Auto-Correlation. A measure of the amplitude of a sound wave, measured in dBPa. A type of channel model in which the received signal is composed of a number of separate delayed clusters. It may also provide public warnings of emergencies which can be broadcast over the cellular network. A term typically used to describe the modulation and coding scheme applied for ts244.008 transmission of a transport block.
Alliance for Telecommunications Industry Solutions.
The TT is the difference between the core specification value and the test limit. In relation to an Information Element IE in a signalling message e. Temporary Identifier 3g;p in Next update.
The cyclic shift indices of the M- sequences are derived from a function of the physical layer cell identity group. These frequencies cover a significant part of the electromagnetic radiation spectrum, ranging from a few kilohertz to hundreds of gigahertz.
