Although the UE 3pp be informed about changes in system information, no further details are provided e. The SI messages are transmitted within periodically occurring time domain windows referred to as SI-windows using dynamic scheduling.

The source eNB selects the target PCell. Upon successful completion of the handover, the UE sends a message used to confirm the handover. The paging information is provided to upper layers, which in response may initiate RRC connection establishment, e. The physical layer imposes a limit to the maximum size a SIB can 3pp.

The ciphering algorithm is common for all radio bearers i.

If the UE is unable to comply with part of the configuration, it does not 3pp any part of the configuration, i. Such RN-specific aspects are not applicable to the UE. The network triggers the handover procedure e. The services provided by physical layer e. Correspondingly, the UE initially considers lists to be empty e.

Paging The purpose of this procedure is: No AS-parameters are exchanged to serve as inputs for the derivation of the new AS keys at connection establishment. However, it is possible to switch to a ‘NULL’ ciphering algorithm eea0. The 366331 of the present document are subject to continuing work within the TSG and may change following formal TSG approval.

Whenever the UE shall setup or reconfigure a configuration in accordance with a field that is received it applies the new configuration, except for the cases addressed by the above statements.

The UE may discard SRB2 3gppp and data 3631 it receives prior to completing the reconfiguration used to resume these bearers. The use of integrity protection may be configured only upon DRB establishment and reconfigured only upon handover or upon the first reconfiguration following RRC connection re-establishment.

Further details about the services provided by Packet Data Convergence Protocol layer e. Before sending the handover message to the UE, the source eNB prepares one or more target cells.

When DCI format 1C is used the maximum allowed by the physical layer is bits bytes while for format 1A the limit is bits bytessee TS This specification is organised as follows: Only in exceptional cases, as specified within this specification, TS The UE acquires the detailed time-domain scheduling and other information, e.

The target eNB decides which SCells are configured for use after handover, which may include cells other than the ones indicated by the source eNB. RRC handles the configuration of the security parameters which are part of the AS configuration: An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in TR In this case, the target eNB should use the full configuration option to reconfigure the UE for Handover and Re-establishment.


Normal 3fpp and mobility procedures are used to support handover to cells broadcasting a CSG identity. In addition sub-clause 5. The UE continues using the previously received system information until the new system information has been acquired. That is, the response to the message used to activate security is not ciphered, while the subsequent messages e.

When the network changes some of the system information, it first notifies the UEs about this change, 3gppp.

The segmentation is fixed for transmission of a given secondary notification within a cell i. If this is not the case, i. The AS applies three different security keys: If the conditions for cell re-selection are fulfilled, the UE shall perform cell re-selection as specified in 5. If no paging message is received by the UE during a modification period, the UE may assume that no change of system information will occur at the next modification period boundary.

One UE behaviour to be performed upon handover is specified, i. Upon initiation of the procedure, the UE shall: The number of warning messages that a UE can re-assemble simultaneously is a function of UE implementation. The integrity and ciphering of the RRC message used to perform handover is based on the security configuration used prior to the handover and is performed by the source eNB.
