Radio telecommunications system and method of operating the same with polling
First Claim
1. A method of performing communication between a first and a second radio link control (RLC)/medium access control (MAC) entity, comprising:
- performing, by the first RLC/MAC entity;
transmitting a set of data blocks from the first RLC/MAC entity to the second RLC/MAC entity;
transmitting a plurality of polling messages to request that the second RLC/MAC entity acknowledge receipt of the set of data blocks transmitted from the first RLC/MAC entity to the second RLC/MAC entity; and
receiving from the second RLC/MAC entity at least one acknowledgement message acknowledging receipt of one or more of the set of data blocks, the at least one acknowledgement message being responsive to a particular one of the plurality of polling messages;
wherein transmitting the plurality of polling messages comprises;
transmitting a first polling message after a previously transmitted polling message, wherein an interval of time between transmission of the previously transmitted polling message and transmission of the first polling message is a first polling interval, andtransmitting a second polling message after the first polling message, wherein an interval of time between transmission of the first polling message and transmission of the second polling message is a second polling interval, wherein the second polling interval is different from the first polling interval, and wherein the second polling interval is determined responsive to at least one parameter of the set of data blocks.

Abstract
An apparatus or method for transmitting data blocks on a communications channel having a radio link between two stations including a user equipment comprises receiving first data blocks from the user equipment, and transmitting second data blocks to the user equipment. A polling interval is dynamically set for the transmission of polling messages to the user equipment after transmission of the second data blocks, the polling interval being set in accordance with at least one of: a size of one or more data blocks received by the apparatus from the user equipment, a size of one or more blocks transmitted from the apparatus to the user equipment, and a service to which the user equipment is subscribed. The apparatus may be used as a PCU in a cellular mobile telephone system.

8. A first radio link control (RLC)/medium access control (MAC) entity configured to wirelessly communicate with a second RLC/MAC entity, wherein the first RLC/MAC entity comprises:
-
an interface to one or more antennas for performing wireless communication; and processing hardware coupled to the one or more antennas via the interface, wherein the processing hardware is configured to; transmit, via the interface, a plurality of polling messages to request that the second RLC/MAC entity acknowledge receipt of a set of data blocks transmitted from the first RLC/MAC entity to the second RLC/MAC entity; and receive, via the interface, from the second RLC/MAC entity at least one acknowledgement message acknowledging receipt of one or more of the set of data blocks, the at least one acknowledgement message being responsive to a particular one of the plurality of polling messages; wherein to transmit the plurality of polling messages, the processing hardware is further configured to; transmit, via the interface, a first polling message after a previously transmitted polling message, wherein an interval of time between transmission of the previously transmitted polling message and transmission of the first polling message is a first polling interval; and transmit, via the interface, a second polling message after the first polling message, wherein an interval of time between transmission of the first polling message and transmission of the second polling message is a second polling interval, wherein the second polling interval is different from the first polling interval, and wherein the second polling interval is determined responsive to at least one parameter of the set of data blocks. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An apparatus, comprising:
-
a wireless interface; and a processing element coupled to the wireless interface, wherein the processing element is configured to; transmit, via the wireless interface, a plurality of polling messages to request that a receiving radio link control (RLC)/medium access control (MAC) entity acknowledge receipt of a set of data blocks transmitted to the receiving RLC/MAC entity; and receive, via the wireless interface, from the receiving RLC/MAC entity at least one acknowledgement message acknowledging receipt of one or more of the set of data blocks, the at least one acknowledgement message being responsive to a particular one of the plurality of polling messages; wherein to transmit the plurality of polling messages, the processing element is further configured to; transmit, via the wireless interface, a first polling message after a previously transmitted polling message, wherein an interval of time between transmission of the previously transmitted polling message and transmission of the first polling message is a first polling interval; and transmit, via the wireless interface, a second polling message after the first polling message, wherein an interval of time between transmission of the first polling message and transmission of the second polling message a second polling interval, wherein the second polling interval is different from the first polling interval, and wherein the second polling interval is determined responsive to at least one parameter of the set of data blocks. - View Dependent Claims (16, 17, 18, 19, 20)
