DCCH physical channel. The DCI control information in formats 0 and 4 facilitates the scheduling of the data in the PUSCH physical channel. The DCI control information in formats 1, 1A, 1B, 1C, 1D and 2, 2B, 2C facilitates the scheduling of data in the PDSCH physical channel. The DCI control information in format 3 facilitates the transmit power control (TPC) of the PUSCH and PUCCH physical channels. The allocation of the resources is shown by the radio network temporary identifier (RNTI) specific to a mobile (C-RNTI, SPS C-RNTI and TPC- RNTI) or to a set of mobiles (P-RNTI, RA-RNTI, TC-RNTI and SI-RNTI). In the FDD mode, the resource allocation for the uplink, signaled in the PDCCH physical channel of the sub-frame n, is applicable to the sub-frame n+4 ms. In the TDD mode, the shift between signaling in the PDCCH physical channel and transmission in the PUSCH physical channel depends on the configuration of the time frame and the number of the sub-frame of the PDCCH physical channel (Table 4.4). 132 VoLTE and ViLTE Configuration of the Number of the sub-frame of the PDCCH physical channel time frame Table 4.4. Shift between signaling in the PDCCH channel and transmission in the PUSCH channel For configuration 0 of the time frame, the shift between signaling in the PDCCH physical channel and transmission in the PUSCH channel depends on the value of the two bits Uplink Index of DCI control information in formats 0 and 4: - for the most significant bit at ONE and the least significant bit at ZERO, the shift is provided in Table 4.5; - for the most significant bit at ZERO and the least significant bit at ONE, the shift is fixed at 7 ms; - for the most significant bit at ONE and the least significant bit at ONE, the mobile can transmit in the two sub-frames previously defined.
