11 Message and Information element abstract syntax
(with ASN.1)
This clause contains definitions for RRC PDUs and IEs using a subset of ASN.1 as specified in [14]. PDU and IE
definitions are grouped into separate ASN.1 modules.
11.0 General
Some messages and/or IEs may include one or more IEs with name "dummy" that are included only in the ASN.1. The
UE should avoid sending information elements that are named "dummy" to UTRAN. Likewise, UTRAN should avoid
sending IEs with name "dummy" to the UE. If the UE anyhow receives an information element named "dummy", it
shall ignore the IE and process the rest of the message as if the IE was not included.
NOTE:
An IE with name "dummy" concerns an information element that was (erroneously) included in a
previous version of the specification and has been removed by replacing it with a dummy with same type.
The UE shall only include the "variable length extension container" when it sends a non critical extension that
according to this specification shall be transferred within this container.
If the abstract syntax of an IE is defined using the ASN.1 type "BIT STRING", and this IE corresponds to a functional
IE definition in tabular format, in which the significance of bits is semantically defined, the following general rule shall
be applied:
The bits in the ASN.1 bit string shall represent the semantics of the functional IE definition in decreasing order of bit
significance;
- with the first (or leftmost) bit in the bit string representing the most significant bit; and
- with the last (or rightmost) bit in the bit string representing the least significant bit.
