Configures individual PHICH transmission entries, indexed by <tx>.
Each entry specifies the group number, sequence index, and per-downlink-subframe HI (ACK/NACK) values.
In TDD, PHICH is transmitted only in downlink subframes; the active subframes depend on the TDD Uplink-Downlink Configuration.
Enables or disables a specific PHICH transmission entry. When Off, the entry is inactive and its HI is not transmitted.
