摘要： A HARQ data reception scheme for a multiradio communication device is disclosed. The communication device operates multiple radio connections and monitors interference level caused to a target radio connection by at least one other radio connection operated in the communication device. A data packet and at least one retransmission data packet are received with the target radio connection. The utilization of the received data packet and the at least one received retransmission data packet in a hybrid automatic repeat request data reception is determined according to the interference level at the time instant associated with the reception of the corresponding data packet. Under high interference, the received data packet may be discarded, and detected and decoded data packets may be weighted for the HARQ combining according to the interference levels associated with the data packets.

摘要： Exemplary embodiments of this invention substantially reduce self-interference between antennas of a multi-antenna electronic device using IRC without basing interference-minimizing effects (e.g., the covariance matrix) on attributes of the received signal. In one, non-limiting exemplary embodiment, a method includes: determining, based on at least one property, a covariance matrix for interference rejection combining (IRC), wherein the covariance matrix is determined prior to reception of a signal for which the IRC is to be used; receiving the signal; and utilizing the determined covariance matrix with the IRC to reduce self-interference of the received signal. In another exemplary embodiment, a method includes: determining at least one temporal property of self-interference for a signal prior to reception of the signal; receiving the signal; and utilizing the determined at least one temporal property to reduce self-interference of the received signal.

摘要： Described herein is a device that includes at least one radio frequency transmitter; at least one radio frequency receiver; a copy block configurable to output a digital representation of a currently transmitted signal and a model having a representation of at least analog circuitry of the at least one radio frequency transmitter and analog circuitry of the at least one radio frequency receiver, as well as possibly one or more antennas. The model generates, in response to the digital representation of the currently transmitted signal, a self-interference compensation signal to compensate, in the digital domain, a signal that is received simultaneously with the currently transmitted signal. Also described are corresponding apparatus, methods, computer program instructions stored in a memory medium, and an integrated circuit embodiment.

摘要： A system for allocating communication resources in an apparatus. For example, an apparatus that is enabled to support a plurality of wireless transports may identify a resource-intensive task to be executed using a wireless transport. Prior to the execution of the resource-intensive task, the apparatus may determine if any wireless links already exist, and whether to alter operational parameters for one or more of the existing wireless links in order to make resources available for expediting completion of the resource-intensive task.
