Abstract:
1. Apparatus for use in a wireless unit for controlling signal levels of wireless messages sent and received by the wireless unit, comprising: a transmitter (TX) gain control device (TX GCD) and receiver (RX) gain control device (RX GCD) for respectively controlling a gain of signals respectively sent by and received by said devices; a GC controller for producing a data block having n data bits representing a gain value; i lines each configured to transfer portions of the data block from the GC controller to a given one of the TX GCD and RX GCD, where 3≦i<n; a data block converting device for converting the data block into i data block portions, each data block portion having a plurality m of control bits appended thereto, combinations of states of the m control bits collectively representing both a function and/or destination and the combination of states of the control bits; each data block portion being applied to an associated one of said i lines; the data block portions from said i lines being combined to reconstruct the original data block; the data block being transferred to the given GCD based on a given combination of state of the control bits; and the given GCD receiving the data block and adjusting a gain of the signal handled by the given GCD based on one or a plurality of methods using the gain value of the data block to thereby maintain the signal handled by the given GCD at a gain value determined by the GC controller.
