Note these comments on the alignment of the scrambling code, from 3GPP Type 18 — Neighbor identities. This page was last edited on 22 Aprilat Languages Deutsch Svenska Edit links. Type 13 — ANSI system information.

N-1 with a repeat period of 8N, where N is a 3gp of 2. The channel format and other details are outline in 3GPP Type 3 — 2.331 identity and reselect information, similar to GSM cell selection parameters Type 4 — Cell reselect parameters for connected mode, if different from those in SIB3. Different operators have different configurations for the inactivity timers, which leads to differences in energy consumption. The TFCI of a radio frame indicates the transport format of the RACH transport channel mapped to the simultaneously transmitted message part radio frame.

The preamble is retransmitted in the next available access slot. This corresponds to a spreading factor of, 64, and 32 respectively for the message data part. The fact that SIBs can span multiple transport frames, or be combined 3bpp shared transport frames, further complicates the set of scheduling possibilities. Furthermore, the signature 3tpp also selected randomly from among the available signatures indicated in SIB5. 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.


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

The standard channel model includes rate-matching, but the sizes line up already, so rate-matching 3gpp a no-op. That information is very useful for understanding the actual meanings of some of the elements they contain.

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

The RACH procedures is as follows: Download in other formats: The terminal decodes AICH the preamble. This corresponds to a spreading factor of for the message control part. The pilot bit pattern is described in table 8. There are a maximum of 16 available signatures. Retrieved 10 April Time and reference position appear to by mandatory. All of the parameters are powers of 2, but the repeat periods can be set independently for each SIB type.

Radio Resource Control – Wikipedia

The sequence of complex valued chips shall be scrambled complex chip-wise multiplication by a complex-valued scrambling code Sdl,n. The downlink power level is measured and the initial RACH power level is set with the proper margin due to the open-loop inaccuracy.

Information on what access slots are available for random-access transmission is given by higher layers. A 10 ms message part consists of one message part radio frame, while a 20 ms message part consists of two consecutive 10 ms message part radio frames.

Type 15 — GPS aiding information. Views Read Edit View history. There’s an overview of this in 3GPP Retrieved from ” https: Type 12 — Measurement control information for connected mode, if different from SIB Type 14 — PHY information.

The best place to see this laid out 255.331 a clear way is in 3GPP Message Formation and ASN. As per 3GPP The set of available signatures is indicated by the SIB5 message, and the UE uses the ASC to determine the subset of that set and access slot to use.

The control part consists of 8 known pilot bits to support channel estimation for coherent detection and 2 TFCI bits. The data and control parts are transmitted in parallel. The simplest way to schedule the messages would be: More details are in 3GPP The transitions to lower energy consuming states occur when inactivity timers trigger.

From Wikipedia, the free encyclopedia. In case of other downlink channels, the scrambling code shall be applied aligned with the scrambling code applied to the P-CCPCH.

Radio Transmission These chips are formed into QPSK symbols and prepared for transmission with the root-raised-cosine channel filter. The operation of the RRC is guided by a state machine which defines certain specific states that a UE may be present in.
