Further details about the services provided by Medium Access Control layer e. Upon initiation of 3gop procedure, the UE shall: The RRC states can further be characterised as follows: The integrity and ciphering algorithms can only be changed upon handover. For RNs 33gpp with an RN subframe configuration, the system information contained in this dedicated signalling replaces any corresponding stored system information and takes precedence over any corresponding system information acquired through the system information acquisition procedure.

When the network changes some of the system information, it first notifies the UEs 336331 this change, i. Performs logging of available measurements together with location and time for logged measurement configured UEs. Unless explicitly stated otherwise in the procedural specification, the system information acquisition procedure overwrites any stored system information, i. Although the UE may be informed about changes in system information, no further details are provided e.
The paging information is provided to upper layers, which in response may initiate RRC 3fpp establishment, 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.
System information may be transmitted a number of times with the same content within a modification period, as defined by its scheduling. 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 Such RN-specific aspects are not applicable to the 363331. UEs may use systemInfoValueTag, e. The handling of the radio bearers after the successful completion of the PDCP re-establishment, e. The source eNB should, for some time, maintain a context to enable the UE to return in case of handover failure.
Paging The purpose of this procedure is: These general principles are illustrated in figure 5. That is, the response to the message used to activate security is not ciphered, while the subsequent messages e. The measured quantities are filtered by the L3 filter as configured in the mobility measurement configuration.
Upon successful completion of the handover, the UE sends a message 363331 to confirm the handover.
For a specific reference, subsequent revisions do not apply. The services provided by physical layer 3633. The AS applies three different security keys: In addition, an overflow counter mechanism is used: Segmentation can be applied for the delivery of a secondary notification. The further details are specified in TS The measurements are based on the time domain measurement resource restriction, if configured. Correspondingly, the UE initially considers lists to be empty e.
The source 3fpp may also provide the target eNB with a list of best cells on each frequency for which measurement information is available, in order of decreasing RSRP. The modification period is configured by system information. If the conditions for cell re-selection are fulfilled, the UE shall perform cell re-selection as specified in 5. At each point in time, the UE keeps a single value for each field except for during handover when the UE temporarily stores the previous configuration so it can revert back upon handover failure.
A term 336331 in the present document takes precedence over the definition of the same term, if any, in TR The segmentation is fixed for transmission of a given secondary notification within a cell i. Release 8 and 9 AS feature handling The SI messages are transmitted within periodically occurring time domain windows referred to as SI-windows using dynamic scheduling.
