The RRC connection setup message contains configuration details
for SRB1 so that later messages can be transferred via SRB1,This allows
subsequent signaling to use the DCCH logical channel. Remember the SRB2 is
always configured after the security activation, so the RRC Connection Setup
message does not include any information regarding SRB 2.
·
RRC Connection setup message include default configuration for
SRB1 but can also include configuration information for PUSCH, PUCCH, PDSCH
physical channels, CQI Reports, Sounding reference signal, antenna
configuration and scheduling requests.

The default configuration for SRB 1 is presented in Table. This
default configuration has been specified by 3GPP within TS 36.331. Using the
default configuration helps to reduce the signaling requirement. The default
configuration for SRB 2 is also presented in Table 132 for information. SRB 2
has a lower priority than SRB 1, i.e. a value of 3 represents a lower priority
than a value of 1. Both SRB 1 and 2 always use acknowledged mode RLC.
·
The RRC Connection Setup message can also define configuration
information for the PDSCH, PUCCH and PUSCH physical channels. It can also
include information regarding uplink power control, CQI reporting, the Sounding
Reference Signal, antenna configuration and scheduling requests
