Section: 5.1 General 5.1.2 General requirements
Content: The UE shall: 1> process the received messages in order of reception by RRC, i.e. the processing of a message shall be completed before starting the processing of a subsequent message; NOTE: Network may initiate a subsequent procedure prior to receiving the UE's response of a previously initiated procedure. 1> within a clause execute the steps according to the order specified in the procedural description; 1> consider the term 'radio bearer' (RB) to cover SRBs, DRBs and MRBs unless explicitly stated otherwise; 1> set the rrc-TransactionIdentifier in the response message, if included, to the same value as included in the message received from the network that triggered the response message; 1> upon receiving a choice value set to setup: 2> apply the corresponding received configuration and start using the associated resources, unless explicitly specified otherwise; 1> upon receiving a choice value set to release: 2> clear the corresponding configuration and stop using the associated resources; 1> in case the size of a list is extended, upon receiving an extension field comprising the entries in addition to the ones carried by the original field (regardless of whether the network signals more entries in total); apply the following generic behaviour unless explicitly stated otherwise: 2> create a combined list by concatenating the additional entries included in the extension field to the original field while maintaining the order among both the original and the additional entries; 2> for the combined list, created according to the previous, apply the same behaviour as defined for the original field.
