the signal received on the PDSCH physical channel and the positive (ACK) or negative (NACK) acknowledgments; - format 3 transports the same information as format 1 by adapting it to the aggregation of radio channels introduced in Release 10. The PUSCH physical channel transmits the UL-SCH transport channel and the UCI control information. For Releases 8 and 9, the simultaneous transmission of PUSCH and PUCCH physical channels is not supported. The transmission of UCI information in the PUSCH physical channel is carried out, on the one hand, together with the transfer of traffic data or RRC VoLTE and ViLTE control, while for the transfer of aperiodic UCI information reports, on the other. For Release 10, the simultaneous transmission of the PUSCH and PUCCH physical channels is supported. The transmission of UCI information in the PUCCH physical channel is maintained when the data traffic or RRC control need to be transferred to the PUSCH physical channel. 4.2. Procedures 4.2.1. Access control 4.2.1.1. Acquisition of the PRACH physical channel The procedure of access to the eNB entity is developed for accessing the physical random access channel (PRACH) that the mobile is going to use to carry out the random access. The different physical channels and physical signals processed by the mobile for the acquisition of the PRACH physical channel can be found in Table 4.3.
