摘要： Certain aspects of the disclosure relate generally to uplink flow control of wireless devices for mitigation of overload issues. A user equipment (UE) may reduce an average transmit power for the uplink channel based on whether an overload metric (e.g., temperature metric) exceeds a threshold value. The UE may perform duty cycling for an uplink control channel when an overactive uplink control channel is a dominating factor in a thermal issue. The UE may further reduce a maximum power transmit limit (MTPL) for one or more uplink channels, such as physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH).

摘要： Techniques for windowing a transmission are disclosed herein. In one aspect of the disclosure, the length of a window used for windowing may be configurable and determined for a transmission based on a configuration of the transmission. The configuration of the transmission may be determined based on one or more parameters such as a system bandwidth, a bandwidth assigned for the transmission, the location of the assigned bandwidth within the system bandwidth, a modulation type used for the transmission, etc. In another aspect of the disclosure, a preferred length for a window may be determined for each of a number of possible configurations of a transmission. Different possible window lengths may be evaluated for each possible configuration based on one or more performance metrics. For each configuration, a window length that can provide the best performance for that configuration may be selected as a preferred window length for that configuration.

摘要： Disclosed are methods and apparatus for sampling rate conversion in a wireless transceiver. The methods and apparatus achieve agile setting of sampling rates or resampling by adaptively setting a sampling rate of a signal based on at least one performance requirement of the transceiver. In particular, the methods and apparatus perform sampling of an input signal at a first sampling rate to gain one or more input signal samples. The input signal samples are then filtered using parallel or polyphase filtering operating at a second sampling rate lower than the first sampling rate. The filtered samples are then interpolated at the second sampling rate to achieve resampling of the input signal. Polyphase filtering affords an effectively high input sampling rate for good spectrum image rejection, while allowing the second sampling rate to be effectively much lower than the first rate, thereby reducing the complexity of multiplier operations for interpolation.

摘要： A device, system, and method adaptively adjusts uplink power transmission to component carriers in carrier aggregation. The method is performed at a user equipment configured with a carrier aggregation functionality including a primary component carrier (PCC) and a secondary component carrier (SCC), the UE using a first transmit power for an uplink transmission on the PCC and using a second transmit power for the uplink transmission on the SCC. The method includes determining whether a total transmit power including the first and second transmit powers for the uplink transmission exceeds a predetermined threshold. The method includes, when the total transmit power exceeds the predetermined threshold, adjusting the first transmit power based on a connectivity parameter for the PCC. The method includes adjusting the second transmit power based on the adjusting of the first transmit power.
