  • Publication number: 20150334584
    Abstract: Performing measurement of a first RAT while connected to a second RAT. The UE may initially communicate with a base station of the second RAT. While maintaining a connection to the base station of the first RAT, the UE may perform base station measurement of the first RAT (e.g., using a single radio of the UE). However, the measurement of the first RAT may be influenced by various factors, such as signal quality metrics of the second RAT. For example, if signal quality metrics are high for the second RAT, measurement of the first RAT may not be desirable, e.g., for battery life reasons.

  • Publication number: 20150257042
    Abstract: Performing selective tune-away by a user equipment (UE). The UE may include a first radio that is configurable to operate according to a first radio access technology (RAT) and a second RAT. The UE may use the radio to communicate using the first RAT and the second RAT using the first radio. The UE may also perform measurement of a received signal strength for the first RAT. The UE may determine if the received signal strength is less than a threshold. Neighbor cell measurement and/or synchronization may be performed if the received signal strength is less than the threshold. However, if the received signal strength is greater than the threshold, the neighbor cell measurement and/or synchronization may not be performed. The UE may continue to perform page decoding for the first RAT using the first radio, e.g., for each discontinuous reception (DRX) cycle of the first RAT.

The UE may operate alternately in active and inactive states in a periodic manner according to DRX cycle timing for each of a plurality of DRX cycles. Paging messages may be checked for while in the active state during each DRX cycle. If a paging message is received, it may be decoded using a joint detection technique. The UE may adaptively determine whether or not to perform neighboring cell measurements during at least a subset of the DRX cycles, and perform neighboring cell measurements according to the adaptive determination. The adaptive determination may be based on one or more of joint detection of paging messages, one or more previous cell measurements, or an amount of motion of the UE.

  • Publication number: 20140029464
    Abstract: Methods and apparatus for correcting quantization errors in signal reception based on estimated network loading including solutions for preserving cellular network performance in low noise, high interference environments. In one embodiment, a data channel is amplified with respect to other signals based on network load during periods of relatively low network utilization. Dynamic modification of the data channel's power level is configured to overcome quantization errors, rather than the true noise floor (which is insignificant in low noise environments). Such solutions provide both the fidelity necessary to enable high degrees of unwanted signaling rejection, while still preserving data channel quality.

  • Publication number: 20130033426
    Abstract: The invention provides a handheld projector and a projection method thereof. The handheld projector includes a projection module, a control module, a detecting module and a steering module. The control module drives the projection module to project an image towards an object, which includes a cursor. The detecting module generates a shift signal according to shift of the handheld projector, and transmits the shift signal to the control module. The control modules drives the steering module to rotate the projection module towards an opposite direction of the shift of the handheld projector, so as to make the image projected by the projection module stay in a fixed position of the object. Through the invention, projected image is not easily shocked, and the user only need move the handheld projector when change of the cursor position is desired, and thus operation convenience is greatly enhanced.
