The same scrambling code is used for the message part, but with a code offset. The BCH transport block is always bits, including a header and data fields. Type 12 — Measurement control information for connected mode, if different from SIB The sequence of complex valued chips shall be scrambled complex chip-wise multiplication by a complex-valued scrambling 25.33 Sdl,n.

A 1 ms RACH preamble is sent with the selected signature. Message encoding is ASN. All of the parameters are powers of 2, but the repeat periods can be set independently for each SIB type. In case of other downlink channels, the scrambling 3bpp shall be applied aligned with the scrambling code applied to the P-CCPCH. 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 operation of the RRC is guided by a state machine which defines certain specific states that a UE 3gppp be present in. 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.

Message Formation and ASN. The timing of the access slots and the acquisition indication is described in subclause 7. Furthermore, the signature is also selected randomly from among the available signatures indicated in SIB5. Download in other formats: From Wikipedia, the free encyclopedia.

The configuration of RRC inactivity timers in a W-CDMA network has considerable impact on 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. Does that mean the whole message is optional? Type 14 — PHY information. This symbol sequence is divided into 15 slots of symbols each. This corresponds to a spreading factor of for the message control 3pgp.

Retrieved 10 April You can get a “clean” copy of that ASN. Type 3 — Cell identity and reselect information, similar to GSM cell selection 225.331 Type 4 — Cell reselect parameters for connected mode, if different from those in SIB3.

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

There’s an overview of this in 3GPP 255.331 All elements are optional. 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.

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 terminal decodes AICH the preamble. The preamble is retransmitted in the next available access slot. This article is based on material taken from the Free On-line Dictionary of Computing prior to 1 November and incorporated under the “relicensing” terms of 3hpp GFDLversion 1.

Each preamble is of length chips and consists of repetitions of a signature of length 16 chips. The fact that SIBs can span multiple transport frames, or be combined into shared transport frames, further complicates the set of scheduling possibilities.

Note these comments on the alignment of the scrambling code, from 3GPP
