Method, system, and integrated circuit for communication in RFID or remote sensor systems
First Claim
1. A method, comprising:
- receiving, at one of a plurality of remote units, a command from a control unit;
in response to the command;
determining a random number specifying a time slot of a first series of time slots for transmitting a second data sequence to the control unit;
in response to a determination that the random number specifies the first time slot in the first series of time slots, determining a new random number;
transmitting, in the first time slot in the first series of time slots, a first data sequence to the control unit; and
receiving a control signal from the control unit, the control signal having been transmitted by the control unit upon detection of an at least partially simultaneous transmission of first data sequences by more than one of the remote units.

Abstract
In certain embodiments, a method may include receiving, at one of a plurality of remote units, a command from a control unit. The method may also include determining a random number specifying a time slot of a first series of time slots for transmitting a second data sequence to the control unit, and, in response to a determination that the random number specifies the first time slot in the first series of time slots, determining a new random number. The method may further include transmitting, in the first time slot in the first series of time slots, a first data sequence to the control unit. The method may further include receiving a control signal. The control signal having been transmitted by the control unit upon detection of an at least partially simultaneous transmission of first data sequences by more than one of the remote units.

9. A system, comprising:
-
a transmitting/receiving device operable to receive a command from a control unit; and an integrated circuit operable to; determine a random number specifying a time slot of a first series of time slots for transmitting a second data sequence to the control unit; and in response to a determination that the random number specifies the first time slot in the first series of time slots, determine a new random number; wherein the transmitting/receiving device is further operable to; transmit, in the first time slot in the first series of time slots, a first data sequence to the control unit; and receive a control signal from the control unit, the control signal having been transmitted by the control unit upon detection of an at least partially simultaneous transmission of first data sequences by more than one of a plurality of systems. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An integrated circuit operable, upon receiving a command from a control unit, to:
-
determine a random number specifying a time slot of a first series of time slots for transmitting a second data sequence to the control unit; in response to a determination that the random number specifies the first time slot in the first series of time slots, determine a new random number; generate a first data sequence for transmittal, in the first time slot in the first series of time slots, to the control unit; and receive a control signal from the control unit, the control signal having been transmitted by the control unit upon detection of an at least partially simultaneous transmission of first data sequences by more than one of a plurality of integrated circuits. - View Dependent Claims (18, 19, 20)
