Publication number: 20080159183Abstract: A first transceiver in a packet-based communications system is operated to achieve efficiencies. The transceiver comprises a receiver and a transmitter for bidirectionally communicating with a second transceiver. In various embodiments, data and control traffic scheduling enables several unrelated items to be bundled during single transmission and/or reception instances. In one aspect, receiver operation involves receiving a first signal from the second transceiver, the first signal requiring that return link information be sent to the second transceiver. A period of time during which the first transceiver can begin a bundled transmission of the return link information and initiating link information that is unrelated to the information carried by the first signal is determined. The bundled transmission of the initiating and return link information is begun during the determined period of time.Type: ApplicationFiled: May 31, 2007Publication date: July 3, 2008Applicant: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Bengt Lindoff, Jacobus Cornelis Haartsen
