Alliance for Telecommunications Industry Solutions. A formal description of a proposed or agreed change to a 3GPP specification. Received Signal Code Power. A time period used to prevent overlap between two different signals. RoT is defined as the ratio between the total power received at a base station and the thermal noise at the base station.
The selected subset changes periodically such that a block of data is transmitted from different antennas at different times. A statement made by a supplier or implementer of an Implementation Under Test IUT which contains or references all of the information in addition to that given in the Implementation Conformance Statement ICS related to the IUT and its testing environment, which will enable the test laboratory to run an appropriate test suite against the IUT. The physical mobile terminal.
These memoranda describe techniques and protocols related to the functioning of the internet and internet-connected systems. An RV is a particular set of systematic and parity bits transmitted from a channel-coded data packet.
The MSC constitutes the interface between the radio system and the fixed networks. ISI is usually caused by frequency selectivity in the propagation channel, giving rise to time-domain dispersion. VoIP is ts24.080 thus a packet-switched technology. A service analogous to Teletex, which broadcasts unacknowledged messages to all mobile terminals within a particular region. The transmission of packetized voice communications using IP.
Such a simple SAW operation cannot on its own utilize the transmission resources during the period between the first transmission and the retransmission.
It handles all Radio Access Bearer-related functions. High-Speed Downlink Packet Access. Similarly to Reference Signal Received 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.
A relaxation factor taken into account in the Ts24.008 Reference 3tpp REFSENS in terms of the minimum received signal strength sufficient to satisfy a specified throughput requirement for a particular transmission configuration. A statistical measure of the magnitude of a series of values. Network Information and Time Zone.
A control system which aims to fix the frequency of an oscillator to ts24.08 of a received signal, by lowering ts24.080 raising the frequency of the oscillator until it is matched to the ts24.0008 signal in both frequency and phase. In LTE the turbo code is constructed by two 8-state constituent encoders and one turbo code internal interleaver.
A mechanism by which the uplink transmission timing is set ts224.008 than the downlink timing as received at the UE, in order to compensate for propagation delay. The information provided can include the type of emergency, as well as advice on action to take. TPD is composed of an element corresponding to the occupied bandwidth as a proportion of the channel bandwidth and an element corresponding to the waveform of the transmitted signal.
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 type of Forward Error Correction FEC code in which k input bits to be encoded are fed into a shift register with a number 3tpp 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 RBG corresponds to a 3bpp of logical channels for ts24008 purposes of uplink buffer status reporting. It arises from a loss of inter-subcarrier orthogonality, for example due to a lack of synchronization accuracy or a large channel delay spread larger than the Cyclic Prefix CP. 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.
RBC handles the maintenance of established radio bearers when the radio resource situation changes, for example due to mobility. TSTD is a multiple antenna transmission technique where a signal is transmitted from only a subset usually one of the available antennas at any time.
A type of Hybrid Automatic Repeat reQuest HARQ scheme where the code rate is progressively reduced by transmitting additional parity information with each retransmission. The reserved resources are not accessible to any other user. Tx24.008 a system may also broadcast information allowing emergency services to request public assistance, for example when life is in danger.
3GPP TS (1 of 24) – Mobile radio interface layer 3: Core network protocols
It cannot be updated more often than every 20 ms. The NCC is used to differentiate between mobile network operators utilizing the same frequencies, for example on an international border where more than one operator has been allocated the same carrier frequency. A term typically used to describe the modulation and coding scheme applied for the transmission of a transport block.
3bpp is defined as the ratio of the filtered mean power in a set bandwidth within the wanted channel to the filtered mean power in an adjacent channel. 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.
Interleaved Frequency Division Multiple Access.
3GPP Message Analyser – 2G, GSM, 3G, UMTS, 4G, LTE message decoding and encoding
By partitioning the signatures into two groups, the PRACH can carry one bit of higher layer information indicating the amount of resource needed for the next uplink message. A unique number which is allocated to each individual mobile station.
International Mobile Subscriber Identity. In a FRC test, the modulation and coding scheme are fixed, i. 33gpp
Online 2G/GSM, 3G/UMTS, 4G/LTE Message Analyser
Refers to signal oscillation frequencies such that if the signal is input to an antenna an electromagnetic field is generated suitable for wireless communication. An electronic device designed to generate a signal of a defined frequency locally 3pp a receiver, as opposed to recovering the frequency from a received signal.
LDPC codes are linear parity-check codes with a classical parity-check equation. Non-GBR bearers do not guarantee any particular bit rate, and are typically used for applications as web-browsing.
