Abstract:
A method and apparatus for handover in a wireless communication system. A connection can be established with a mobile station (110). A measurement report can be received at a source base station (120) from the mobile station. The source base station can determine that the mobile station should perform a handover from the source base station to the target base station (130). Timing advance information can be received at the source base station from the target base station. The timing advance information can be forwarded from the source base station to the mobile station. A connection of the mobile station can be switched from the source base station to the target base station.
Abstract:
A method for scheduling a wireless communication entity (103) based on channel quality information provided by the wireless entity, wherein scheduling is discontinued if channel quality information is not received from the wireless communication entity over a specified number of frames or if the channel quality information provided is insufficient to support a control channel. The wireless entity may discontinue reporting channel quality information if the channel quality measured over a specified number of frames is below a threshold. Scheduling may be discontinued by blocking, or removing or preempting the scheduling of the wireless entity.
Abstract:
A method in a wireless communication network infrastructure scheduling entity (102), including allocating a radio resource to a schedulable wireless communication entity in the wireless communication network, the radio resource allocated based on a maximum power available to the schedulable wireless communication entity for the radio resource allocated, the radio resource allocated based on an interference impact of the schedulable wireless communication entity operating on the radio resource allocated.

Abstract:
The present disclosure describes a method and apparatus for transmit power calibration in a frequency division multiplexed wireless system (100). The method may include receiving (320), at a user equipment (120), a signal from a base station (130) in a frequency division multiplexed wireless system, mapping (330), in response to receiving the signal from the base station, a power control calibration region to an uplink symbol in a subframe to establish a mapped uplink symbol using predetermined criteria, and performing (340) a calibration transmission during the mapped uplink symbol for performing transmit power control calibration. The method can also include calibrating (350) a transmit power based on the calibration transmission and transmitting (360) data at the calibrated transmit power on at least one other symbol following the mapped uplink symbol.
Abstract:
A method and apparatus for handover of a mobile station (110) from a source base station (120) to a target base station (130). A connection can be established with a mobile station. A measurement report can be received from the mobile station. The source base station can determine the mobile station should perform a handover from the source base station to a target base station. A random access channel preamble can be generated at the source base station in response to determining the mobile station should perform a handover. The random access channel preamble can include a temporary mobile equipment identifier for the mobile station. The random access channel preamble can be sent to the mobile station. The connection with the mobile station can be switched from the source base station to the target base station.
