Method for acknowledging messages in a communication system
First Claim
Patent Images
1. A method comprising the steps of:
- at a first device in a wireless system whereby the wireless system has a protocol comprising at least one superframe, wherein the at least one superframe is an interval of time between consecutive beacon messages;
receiving a message in a first superframe;
processing the message; and
if the message is processed during a first time period, transmitting an acknowledgement message during a second time period, otherwise transmitting the acknowledgment message during a third time period, wherein the second time period and the third time period are exclusive of each other, and wherein the first time period, the second time period, and the third time period are in the first superframe.

Abstract
At a first device (102 or 104), a message is received and processed. If the message is processed during a first time period, the first device transmits an acknowledgement message during a second time period; otherwise the first device transmits the acknowledgment message during a third time period. The second time period and the third time period are exclusive of each other.

11. A method comprising the steps of:
-
receiving a message in a first superframe, wherein the at least one superframe is an interval of time between consecutive beacon messages;
determining whether the message can be processed during a first time period;
if the message can be processed during the first time period, processing the message and transmitting an acknowledgement message during a second time period, wherein only the acknowledgement message is allowed to be transmitted during the second time period; and
if the message cannot be processed during the first time period, setting a flag to transmit the acknowledgement during a third time period after the message has been processed, wherein the second time period and the third time period are exclusive of each other, and wherein the first time period, the second time period, and the third time period are in the first superframe.

12. A method comprising the steps of:
-
at a first device in a wireless system whereby the wireless system has a protocol comprising at least one superframe, wherein the at least one superframe is an interval of time between consecutive beacon messages;
receiving a message;
determining whether the message is of a first type or a second type;
if the message is of the first type, setting a flag when the message is addressed to the first device otherwise, incrementing a counter value, wherein the counter value is associated with a period of time;
if the message is of the second type, transmitting an acknowledgement message for the message for which the flag was set after waiting the period of time associated with the counter value at the time the flag was sets, wherein the message and the acknowledgement message are in one superframe. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method comprising the steps of:
-
at a first device in a wireless system whereby the wireless system has a protocol comprising at least one superframe, wherein the at least one superframe is an interval of time between consecutive beacon messages;
receiving at least one type-one message;
incrementing a counter value each time a type-one message is received that is addressed to another device, wherein the counter value is associated with a period of time;
setting a flag each time a type-one message is received that is addressed to the first device;
receiving a type-two message;
transmitting an acknowledgement message for each message in which a flag was set after waiting the period of time associated with the counter value at the time each flag was set, wherein the at least one type-one message, the type-two message, and the acknowledgement message are in one superframe.
