摘要： A user equipment (UE) prioritizes searches and/or measurements of neighbor cells/frequencies based on a level of mobility of a UE. In one instance, the UE identifies a priority of a layer of a radio access technology (RAT) to be measured or searched and identifies a level of mobility of the UE. A sensor module of the UE may determine the level of mobility of the UE and generate an indication corresponding to the level of mobility of the UE. The UE prioritizes a periodicity of interlayer search and/or measurement based on the priority of the layer to be measured and the level of the mobility of the UE.

摘要： A method and apparatus for improved downlink data transport with hybrid automatic repeat request (HARQ) feedback and a measurement gap are provided. A user equipment (UE) receives from a network a transmission grant for downlink data on a first control channel. The UE receives the data from the network via a transport channel. In response to the received data, the UE determines whether transmission of an acknowledgement message falls in a measurement gap. Upon determining that the transmission of the acknowledgement message by the UE falls in the measurement gap, and prior to receiving from the network a retransmission grant for the data on the first control channel, the UE sends the acknowledgement message on a second control channel in a sub-frame following the measurement gap. The first control channel is associated with the second control channel.

摘要： A method and apparatus for controlling uplink transmit power with optimum delay is described. A transmit power control command may be received. A time slot of the transmit power control command may be determined. Based on the time slot, it may be determined to decode the transmit power control command, with a delay. The transmit power control command may be decoded, after the delay, using a transmit power control command decoding graph by determining a strength of the transmit power control command and plotting the strength on the transmit power control command decoding graph. The transmit power control command decoding graph may include regions. Decoding the transmit power control command, after the delay, may be based on a region associated with plotting the strength of the transmit power control command.

摘要： Methods and apparatuses are presented for managing a multi-subscriber identity module (SIM) user equipment (UE) such that data throughput may be improved in a dual-SIM, dual active (DSDA) scenario. For example, a method is presented that includes acquiring first timing information of a first subscription and second timing information of a second subscription. Additionally, the example method may include detecting a first conflict between communications of the first subscription and the second subscription in a time slot of a first time interval. Moreover, the example method may include estimating one or more additional conflicts in one or more subsequent time intervals based on timing of the time slot, the first timing information, and the second timing information. Further, the example method may include respectively adjusting one or more transmit block sizes (TBS) for each of the one or more subsequent time intervals.

摘要： Embodiments described herein provide a method and apparatus for monitoring and correcting a transmit signal. A first sample is taken before the signal is input to a digital to analog converter (DAC) in a transmit chain. A second sample is taken of the transmit signal after the signal has passed through the power amplifier (PA). The first and second transmit samples are then compared and an equalizer interpolation value is determined. This equalizer interpolation value is applied to the transmit signal before transmission to provide a transmit signal with improved quality. The apparatus includes a feedback receive correction unit; a time domain processor in communication with the feedback receive correction unit; a frequency domain processing equalizer in communication with the time domain processor; an equalizer interpolation unit; an absolute value squaring unit in communication with the equalizer interpolation unit; and a processor for computation of a transmit quality parameter.

摘要： The various embodiments include methods and apparatuses for canceling nonlinear interference during concurrent communication of multi-technology wireless communication devices. Nonlinear interference may be estimated using a multi-model radial basis function neural network with Hammerstein structure by executing a radial basis function on aggressor signals at a hidden layer of the radial basis function neural network with Hammerstein structure to obtain hidden layer outputs, augmenting aggressor signal(s) by weight factors, infusing the hidden layer outputs by infusion factors, and, executing a linear combination of the augmented output, at an intermediate layer to produce a combined hidden layer outputs. At an output layer, a linear filter function may be executed on the hidden layer outputs to produce an estimated nonlinear interference used to cancel the nonlinear interference of a victim signal.
