Type 3 — Cell identity and reselect information, similar to GSM cell selection parameters Type 4 — Cell reselect parameters for connected mode, if different from those in SIB3. There’s an overview of this in 3GPP In case of other downlink channels, the scrambling code shall be applied aligned 3gpp the scrambling code applied to the P-CCPCH.

The terminal randomly selects one of the RACH sub-channels from the group its access class allows it to use. Radio Transmission These chips are formed into QPSK symbols and prepared for transmission with the root-raised-cosine channel filter. OSI model by layer 7.

MARBEN ASN.1 Solutions: 3GPP UMTS Messages Decoder

Views Read Edit View 3bpp. Languages Deutsch Svenska Edit links. The same scrambling code is used for the message part, but with a code offset. Download in other formats: The control part consists of 8 known pilot bits to support channel estimation for coherent detection and 2 TFCI bits.

This article is based on material taken from the Free 253.31 Dictionary of Computing prior to 1 November and incorporated under the “relicensing” terms of the GFDLversion 1. This symbol sequence is divided into 15 slots of symbols each. Type 13 — ANSI system information. There are a maximum of 16 available 52.331. Type 18 — Neighbor identities. The set of available signatures is indicated by the SIB5 message, and the UE uses the ASC to determine the 25.3331 of that set and access slot to use.


The simplest way to schedule the messages would be: All of the parameters are powers of 2, but the repeat periods can be set independently 255.331 each SIB type. The UE selects the scrambling code number by adding the code number of the downlink primary scrambling code and the preamble scrambling code number from SIB5. Message Formation and ASN. That information is very useful for understanding the actual meanings of some of the elements they contain. The best place to see this laid out in a clear way is in 3GPP 3gpp The data and control parts are transmitted in parallel.

You can get a “clean” copy of that ASN. The purpose of this procedure is to establish the appropriate uplink power level for the UE, since CDMA is exquisitely sensitive to variations in relative received power. The pilot bit pattern is described in table 8. The channel format and other details are outline in 3GPP The fact that SIBs can span multiple transport frames, or be combined into shared transport frames, further complicates the set 3gp scheduling possibilities.

Note these comments on the alignment of the scrambling code, from 3GPP The configuration of RRC inactivity timers in a W-CDMA network has considerable impact 2.5331 the battery life of a phone when a packet data connection is open.

N-1 with a repeat period of 8N, where N is a power of 2. The operation of the RRC is guided by a state machine which defines certain specific states that a UE may be present in. Does that mean the whole message is optional? This corresponds to a spreading factor of for the message control part.


Type 15 — GPS aiding information. This corresponds to a spreading factor of, 64, and 32 respectively for the message data part.

These chips are formed into QPSK symbols and prepared for transmission with the root-raised-cosine channel filter.

Radio Resource Control

The standard channel model includes rate-matching, but the sizes line up already, so rate-matching is a no-op. Each preamble is of length chips and consists of repetitions of a signature of length 16 chips. Each slot consists of two parts, a data part to which the RACH transport channel is mapped and a control part that carries Layer 1 control information. By using this site, you agree to the Terms of Use and Privacy Policy. In this case, the scrambling code is thus not necessarily applied aligned with the frame boundary of the physical channel to be scrambled.

The terminal decodes AICH the preamble. Type 14 — PHY information. Retrieved 10 April List of mobile phone generations. As per 3GPP RACH transmissions from the user consists of two parts: The timing of the access slots and the acquisition indication is described in subclause 7.

Time and 25.3311 position appear to by mandatory. Retrieved from ” https: The different states in this state machine have different amounts of radio resources associated with them and these are the resources that the UE may use when 3ggpp is present in a given specific state. This page was last edited on 22 Aprilat The UE can start the random-access transmission at the beginning of a number of well-defined time intervals, denoted access slots.
