摘要： A system and method for determining an initial mean open loop power level of a pilot channel of a reverse traffic channel for a mobile terminal. The initial open loop power level enables handoff of an active call from a first access network to a second access network. A handoff initialization request is from the first access network. A mean received power level of the forward link of the second access network is measured and transmitted to the second access network. An open loop power adjustment factor is received from the second access network. The initial mean open loop power level is set based on the open loop power adjustment factor.

摘要： A method, system and device are provided for avoiding in-device coexistence interference between different radio technologies deployed in adjacent bands on the same device by controlling and separating the LTE signalling and the non-LTE signalling using dedicated time intervals to separate LTE signalling from non-LTE signalling. Coexistence interference is also avoided by providing a hybrid automatic repeat request (HARQ) mechanism which accounts for coexistence interference by providing a fixed or variable on-interval parameter and an activity parameter indicating whether non-LTE activity is present to maximize a time interval for non-LTE devices without interference from LTE activity on the same device.

摘要： In some implementations, a method of wireless communications between a wireless communications network and wireless user equipment includes receiving, using a primary Time Division Duplex (TDD) configuration, data on a primary component carrier in a first frequency band. Using a secondary TDD configuration, data on a secondary component carrier is received in a second frequency band different from the first frequency band. A Hybrid Automatic Repeat Request (HARQ) for data received on the secondary component carrier is transmitted using a supplemental TDD configuration. A transmission or retransmission on the secondary component carrier uses a supplemental TDD configuration as well. The supplemental TDD configuration is different from the secondary TDD configuration. Furthermore, an uplink supplemental configuration may be different from a downlink supplemental configuration.
