摘要： Conventional mode adaptation does not account for the gain imbalance between channels for measurement and for data reception. Therefore, the precoder, which is selected based on the measurement channel may not be the optimal precoder for the data reception channel. By maintaining relative SINR ordering between transmission modes, a receiver (110) may select the transmission mode for a transmitter (130) that maximizes the actual throughput even in the presence of inter-antenna gain increase or decrease.

摘要： Systems and methods for mitigating self-interference at a wireless device (14) in a cellular communications network (10) are disclosed. In one embodiment, a network node (12, 14) obtains one or more self-interference parameters for self- interference at the wireless device (14) within a downlink frequency band utilized by the wireless device (14). In one embodiment, the one or more self-interference parameters include a frequency location of the self-interference, a strength of the self- interference, or both the frequency location and the strength of the self-interference. The network node (12, 14) then controls uplink transmission by the wireless device (14), downlink reception by the wireless device (14), and/or downlink transmission to the wireless device (14) in such a manner that the self-interference at the wireless device (14) is mitigated.

摘要： Devices and methods for adjusting resource management procedures in a User Equipment (UE) machine device communicating with one or more nodes in a communication network. In one embodiment, a method includes determining, during a first time period, the number of handovers, N, for the UE from a serving node to a different node. The method further includes comparing the value, N, to a threshold, wherein if the value, N, is greater than the threshold, mobility pattern information for the UE includes an indication of high mobility, and if the value, N, is less than or equal to the threshold, the mobility pattern information includes an indication of low mobility. The method also includes transmitting machine device capability information, including the indicated mobility pattern information, to be used for determining an adjustment to a resource management procedure for the UE.

摘要： An access node is configured to adapt uplink power control procedures based on the device attributes of a wireless device. The device attributes may, for example be the mobility, energy profile, or characteristic traffic pattern of the wireless device. The adaptive uplink power control procedure may be used to minimize or reduce power consumption, to improve resource utilization efficiency, or to reduce interference levels.

摘要： Devices and methods for iteratively sampling a wideband signal in order to recover one or more narrowband signals are disclosed. In one aspect, a wideband signal is received and the signal is sampled using a sampling device, which includes an amplifier with an initial gain level, to produce a plurality of sampled signals. A first set of narrowband signals may be recovered from the plurality of sampled signals. Then, the wideband signal is re-sampled to produce a second plurality of sampled signals. The re-sampling includes increasing the gain of the amplifier to a second level and suppressing a component of the wideband signal. A second set of narrowband signals may then be recovered from the second set of sampled signals.

摘要： Devices and methods for adjusting resource management procedures based on machine device capability information are disclosed. In one aspect, a method for adjusting resource management procedures in a machine device communicating with a node operating in a communication network includes receiving a first message from the machine device, the first message including machine device capability information, processing the received machine device capability information to determine an adjustment to a resource management procedure, and transmitting a second message to the machine device, the second message including the determined resource management procedure adjustment. The first and second messages may be radio resource control (RRC) messages, such as RRC connection request and setup messages.
