Download in other formats: That information is very useful for understanding the actual meanings of some of the elements they contain. All of the parameters are powers of 2, but the repeat periods can be set independently for each SIB type. 3gp; details are in 3GPP The same scrambling code is used for the message part, but with a code offset. The set of available signatures is indicated by the SIB5 message, and the UE 2.5331 the ASC to determine the subset of that set and access slot to use.

Type 13 — ANSI system information. Typically the RACH preamble detection and AICH response is done solely in the physical layer since there is no information or handling needed from the higher layers. The data and control parts are transmitted in parallel. 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 it is present in a given specific state.

This symbol sequence is divided into 15 slots of symbols each. Languages Deutsch Svenska Edit links.

3GPP Specification #: 25.331 version 14.1.0 – ASN.1 code

The BCH transport block is always bits, including 3glp header and data fields. The major functions of the RRC protocol include connection establishment and release functions, broadcast of system information, radio bearer establishment, reconfiguration and release, RRC connection mobility procedures, paging notification and release and outer loop power control.

You can get a “clean” copy of that ASN.

N-1 with a repeat period of 8N, where N is a power of 2. RACH transmissions from the user consists of two parts: The timing of the access slots and the acquisition indication is described in subclause 7. The standard channel model includes rate-matching, but the sizes line up already, so rate-matching is a no-op.

The configuration of RRC inactivity timers in a W-CDMA network has considerable impact on the battery life 2.331 a phone when a packet data connection is open.

3GPP Specification #: version – ASN.1 code –

The channel format and other details are outline in 3GPP This corresponds to a spreading factor of, 64, and 32 respectively for the message data part.

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. There’s an overview of this in 3GPP The preamble is retransmitted in the next available access slot. Furthermore, the signature is also selected randomly from among the available signatures indicated in SIB5. Each slot consists of two parts, a data 25.31 to which the RACH transport channel is mapped and a control part that carries Layer 1 control information.

The downlink power level is measured and the initial 25.331 power level is 3g;p with the proper margin due to the open-loop inaccuracy. All elements are optional. This page was last edited on 22 Aprilat The TFCI of a radio frame indicates the transport format of the RACH transport channel mapped to the simultaneously transmitted message part radio frame.


Message Formation and ASN. Does that mean the whole message is optional?

This corresponds to a spreading factor of for the message control part. The UE can start the random-access transmission at the beginning of a number of well-defined time intervals, 25.33 access slots. Type 14 — PHY information.

By using this site, you agree to the Terms of Use and Privacy Policy. The pilot bit pattern is described in table 8. Information on what access slots are available for random-access transmission is given by higher layers. The RRC idle mode no connection has the lowest energy consumption. Views Read Edit View 25.31. Each preamble is of length chips and consists of repetitions of a signature of length 16 chips.

In this case, the scrambling code is thus not necessarily applied aligned with the frame boundary of the physical channel to be scrambled.

The purpose of this procedure is to establish the appropriate uplink power level for the UE, since CDMA is exquisitely sensitive to variations 255.331 relative received power.

Type 18 — Neighbor identities. Note these comments on the alignment 3ggpp the scrambling code, from 3GPP The channel bits are interleaved, split into 2 bit radio frames and interleaved again.
