    摘要: Methods and apparatus for mitigating in-device interference are described. The methods may include an in-device interference event (e.g. an interference situation), and the processing of events may depend on the priority of the technologies. A handover to another frequency or radio access technology (RAT) may occur in case a co-existing technology may be activated. The network may signal to the device a list of frequencies or RATs that it may be allowed to measure and handoff to. A network may provide a scaling value that the device may use to speed up reaction to the interference. The device may apply a scaling factor to an “out of synch’ counter and/or the radio link failure (RLF) tinier used for the RLF procedure. The device may apply different scaling factors for the measurements and time to trigger events. The device may trigger a report to the network requesting gaps for an alternate RAT.

    摘要: Techniques and apparatus for efficiently determining the radio link control (RLC) protocol data unit (PDU) size and flexible RLC PDU creation for multi carrier operation are disclosed. An example wireless transmit/receive unit (WTRU) calculates a maximum amount of data allowed to be transmitted for a current transmission time interval (TTI) for each of a plurality of carriers, and selects an RLC PDU data field size such that each RLC PDU to be multiplexed to a medium access control (MAC) PDU matches a minimum of the maximum amount of data calculated for the carriers. The maximum amount of data may, for example, be calculated based on an applicable current grant for each carrier for the current TTI. The RLC PDU may be generated for the later TTI on a condition that an amount of data in outstanding pre-generated RLC PDUs for a particular logical channel is less than or equal to 4N times the minimum of the maximum amount of data allowed to be transmitted by the applicable current grant for the carriers for the current TTI, where N is a number of activated carriers. The maximum amount of data may be calculated based on a remaining power on each carrier.
