It is used for all user data, as well as for broadcast system information which is not carried on the Physical Broadcast CHannel PBCHand for paging messages. A downlink logical channel which is used to notify UEs of an incoming call or a change of system information.
A type of 3hpp Multiple-Output MIMO technology by which parallel streams are transmitted, with each stream being addressed to a different user. 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. Received Signal Strength Indicator. They have a wider bandwidth than the data signals.
LBRM shortens the length of the virtual circular buffer of the code block segments for certain large sizes of Transport Block TBand therefore sets a lower bound on the code rate. Input Offset Value – Unconfirmed Information. The LLR gives information about the most likely value of the bit and about the reliability of that estimate.
3GPP TS (1 of 24) – Mobile radio interface layer 3: Core network protocols
A PWS provides the ability to broadcast warnings to alert the public to major emergencies, such as natural and other disasters. An element offering applications that require the control of Internet Protocol IP bearer resources, such as dynamic policy ts24.0008 charging control. Random Access Preamble IDentifier. For radio bearers which need error-free transmission, the RLC layer also performs retransmission to recover from packet losses. If all the column vectors in the 3gp have equal magnitude, the matrix is said to possess the constant modulus property.
The terminals connect to the core network via the access network which is RAT-specific. These two codes are two different cyclic shifts of a single length M-sequence. The periodic switching off of a transmitter, usually to save energy.
Temporary Logical Link Identity. Such a simple SAW operation cannot on its own utilize the transmission resources during the period between the first transmission and the retransmission.
Used in the GPRS ciphering process. Coded Orthogonal Frequency Division Multiplexing. The ratio between the power of the Radio Frequency RF carrier bearing the wanted signal and the total power of interfering signals.
3GPP Message Analyser – 2G, GSM, 3G, UMTS, 4G, LTE message decoding and encoding
A transmission scheme between a transmitter equipped with multiple antennas and a receiver equipped with a single antenna. RBC is involved in the release of radio resources associated with radio bearers, for example at session termination or 3gop. There is one RLC entity per radio bearer. An organisation 3hpp primary activities are developing, managing and promulgating standards. In general, a signal of fixed polarity i. It comprises the transport network control plane and the transport network user plane.
Online 2G/GSM, 3G/UMTS, 4G/LTE Message Analyser
It is usually also the time over which data blocks are encoded for physical transmission. A simple Automatic Repeat reQuest ARQ technique, in which, upon transmission of a transport block, the transmitter stops and awaits feedback from the receiver before making any further transmissions.
In relation to an Information Element IE in a signalling message e. Used in conformance testing, to set the desired power of received signals or interference, for example ts24.080 propagation loss. A set of coefficients describing the complex im- pulse response or frequency-domain characteristic of a radio channel from one or more transmit antennas to one or more receive antennas. The grouping of PRBs in this way enables the signalling overhead to be reduced for downlink transmission resource allocation.
An IDFT transforms a finite frequency domain sequence into a finite time-domain sequence. ISI is usually caused by frequency selectivity in the propagation channel, giving rise to time-domain dispersion. Each user is enabled to decode its own stream by virtue of its antenna s being spatially separated from those of other users, together with spatial decorrelation of the transmitting antennas. Te24.008 Fast Fourier Transform. The process is handled in a serial manner in contrast to Parallel Interference Cancellation PIC where the streams are simultaneously processed at each stage.
Used in tests for audio noise arising from electromagnetic interference.
Network Information and Time Zone. Multimedia Broadcast and Multicast Service. Adjacent Channel Rejection Ratio. Used for paging and registration purposes. Equipment that provides the functions necessary for the operation of access protocols by a user. The index reported by the UE to indicate the estimated power headroom.
In addition it can handle multiple streams and is tolerant of network-level faults through support of multi-homing. The UE-manufacturer-declared supply voltage level from a battery or mains up to which a UE has to fulfil all the LTE specification requirements.
A statistical measure of the magnitude of a series of values.
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.
