FAQ's

When is Buffer Status Report (BSR) triggered?

According to 3GPP, • When UL data, for a logical channel which belongs to a specific LCG, becomes available for transmission in the RLC entity or in the PDCP entity and either the data belongs to a logical channel with higher priority than the priorities of the logical channels which belong to any LCG and for which data is already available for transmission, or there is no data available for transmission for any of the logical channels which belong to a LCG, in which case the BSR is referred below to as "Regular BSR" • When UL resources are allocated and number of padding bits is equal to or larger than the size of the Buffer Status Report MAC control element plus its subheader, in which case the BSR is referred below to as "Padding BSR" • retxBSR-Timer expires and the UE has data available for transmission for any of the logical channels which belong to a LCG, in which case the BSR is referred below to as "Regular BSR" • periodicBSR-Timer expires, in which case the BSR is referred below to as "Periodic BSR".

What is the content of a Random Access Response (RAR) MAC signaling message?

A MAC RAR consists of three major fields, the Timing Advance Command, the UL Grant for next message 3 and the Temporary C-RNTI

When UE triggers RRC Connection Re-establishment procedure?

UE Triggers RRC Connection Reestablishment procedure on following condition: • Upon detecting Radio Link Failure • Handover Failure • Mobility From E-UTRA Failure • Integrity Failure Indication Received From Lower Layers • RRC Connection Reconfiguration Failure
