RRC Connection Setup

·         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
