WebOct 7, 2024 · PHICH is placed in the first OFDM symbol of the sub-frame. Each PHICH consists of 3 REGs (12 REs) and multiple PHICHs can use the same set of REGs known as PHICH groups. This is made possible by … WebThen how the PBCH can carry the antenna configuration in it ? It is done by using special CRC mask (the number of bit stream being masked (XORed) over the CRC bits. Number of CRC bits for PBCH is 16 bits, so the length of the CRC mask is 16 bit as well. Following tables shows the types of CRC mask representing each of the antenna configurations. shiny beacon exampleWebPHICH = Physical HARQ Indicator Channel State Choice: Off On Default: On Double-click or use the drop-down menu to turn the channel On or Off.

WebThere is a special case where PHICH configuration can be extended which can be only used with higher CFIs for PDCCH. This seemed over-complication and so I decided to not include this in the table. In case you are interested, with Extended PHICH, the CFI used will also be 3 for all Bandwidths, and 2 or 3 for 1.4 MHz. WebThe MIB contains system bandwidth, system frame number (SFN), and physical hybrid-ARQ indicator channel (PHICH) configuration, and is transmitted with a fixed modulation and coding scheme in a fixed set of physical resources.
