Abstract: The present application relates to of the communication field and discloses a method, device and system for implementing frequency point switch based on CR. The method comprises: determining, by a cognitive base station, a candidate working frequency point for UE deployed in a cognitive frequency band; then sending to the UE broadcast information which at least carries the candidate working frequency point and instructing the UE to switch from the working frequency point currently used thereby to the candidate working frequency point by way of a frequency point switching command. In this way, the UE deployed in the cognitive frequency band can achieve frequency point switch quickly and accurately according to the instruction from the cognitive base station when an incumbent user accesses the working frequency point currently used by the UE, effectively avoiding interference to the incumbent user and thereby ensuring the service performance and service continuity of the system.

Abstract: A portable communications module (600) of FIG. 6 has an input (621) coupled to receive an incident signal. The input (621) split out a first audio channel containing a context audio track from the incident signal and directs the first audio channel along a first audio output path for selective audio output from a speaker (634, 620) either internally within or external to the module. The input (621)also directs a second audio channel in the incident signal to an RF audio transmitter chain for broadcast, the second audio channel comprising a composite audio signal from a plurality of audio tracks, each audio track embedded with a unique activation code that is present for substantially an entire duration of audio activity in each audio segment of each track. The input (621) is further arranged to apply a tone encoded signal in the incident signal to at least a tone decoder (640) in a data transmitter chain distinct from the audio transmitter chain (642).

Abstract: A system-on-chip including a host interface module configured to interface the system-on-chip to a host processor of a wireless device and to communicate with the host processor of the wireless device via a bus. The bus uses an application programming interface of the system-on-chip. The host processor uses the application programming interface to configure a power save mode of the system-on-chip. A power management module operated the system-on-chip in the power save mode without performing a handshake with the host processor via the bus in response to the host processor stopping communication with the system-on-chip. The handshake includes (i) sending a request to enter the power save mode to the host processor via the bus and (ii) receiving an acknowledgement of the request from the host processor via the bus.

Abstract: Certain aspects of the present disclosure relate to a hybrid approach for Physical Downlink Shared Channel (PDSCH) Interference Cancellation (IC). In certain aspects, if the PDSCH information is known for a serving cell but not be known for interfering cell(s), a hybrid approach that involves using Codeword-level IC (CWIC) for the serving cell and using Symbol-level IC (SLIC) for the interfering cells may be used for better IC performance. The hybrid IC approach may start with a UE attempting to decode the serving cell PDSCH. If the decode is unsuccessful, the UE may perform CWIC for the serving cell followed by SLIC using the results of the CWIC stage. After the SLIC stage, the UE may attempt to decode the serving cell PDSCH again. The UE may perform multiple operations of this method until the serving cell PDSCH is successfully decoded or a maximum number of iterations is reached.

Abstract: A first radio base station (1A) calculates a traffic amount ratio in the first radio base station (1A). Further, when the traffic amount ratio is equal to or greater than a threshold value, the first radio base station (1A) controls to transmit interference information. Under this control, the first radio base station (1A) performs a measurement of interference power, a generation of the interference information and the transmission of the interference information to a second radio base station (1B). On the other hand, when the traffic amount ratio is less than the threshold value, the first radio base station (1A) controls to halt the transmission of the interference information. Under this control, the first radio base station (1A) performs none of the measurement of interference power, the generation of the interference information and the transmission of the interference information to the second radio base station (1B).

Abstract: The invention relates to a method in a radio communications network for controlling a transmission power of a user equipment (12) transmitting data to a radio base station (10) in the radio communications network. The radio base station (10) retrieves a target signal to interference ratio value and measures a signal to interference ratio of a signal transmitted with a current transmission power from the user equipment (12).

The radio base station (10) then transmits the power control command to the user equipment (12).

Abstract: Embodiments provide systems and methods for aligning the supply voltage signal applied to a power amplifier (PA) with the radio frequency (RF) output signal of the PA in a wireless device. The RF output signal is generated by applying a transmit signal to a transmit path of the wireless device. The supply voltage is generated by applying an envelope tracking (ET) signal, based on the transmit signal, to an envelope tracking (ET) path of the wireless device. Embodiments operate by estimating the delays of the ET path and the transmit path, and then controlling a relative delay between the transmit signal and the ET signal accordingly. In an embodiment, estimation of the delays of the ET path and the transmit path is done by correlating respective signals of each path.
