    摘要: One embodiment of the present invention provides a system for setting uplink power-control parameters for a cell within a wireless network. During operation, the system receives parameters associated with uplink power for a plurality of user devices within the cell over a predetermined time interval, and averages the received parameters over the user devices and the predetermined time interval to obtain an averaged parameter. The system then determines a set of power-control parameters for the cell based on the averaged parameter, and sends the set of power-control parameters to the user devices to allow the user devices to control transmission power using the set of power-control parameters.

    摘要: Methods and devices are provided for communicating data in a wireless channel. In one example, a method includes adapting the transmission time interval (TTI) length of transport container for transmitting data in accordance with a criteria. The criteria may include (but is not limited to) a latency requirement of the data, a buffer size associated with the data, a mobility characteristic of a device that will receive the data. The TTI lengths may be manipulated for a variety of reasons, such as for reducing overhead, satisfy quality of service (QoS) requirements, maximize network throughput, etc. In some embodiments, TTIs having different TTI lengths may be carried in a common radio frame. In other embodiments, the wireless channel may partitioned into multiple bands each of which carrying (exclusively or otherwise) TTIs having a certain TTI length.

    摘要: In order to minimize the control signaling overhead associated with transmitting CQI data from mobile stations to base stations in wireless communication networks supporting MU-MIMO, the CQI during MU-MIMO operation is estimated based on SU-MIMO CQI data, mobile station geometry data, and mobile station PMI (Precoding Matrix Index) data. More particularly, the base station maintains and updates a knowledge pool that correlates geometry data and learned impact of interfering precoder data to degradation of CQI values responsive to switching from SU-MIMO operation to MU-MIMO operations. Then, when the base station switches from SU-MIMO operation to MU-MIMO operation, it consults the knowledge pool to predict the degradation in CQI and subtracts them from the known, pre-switching SU-MIMO CQI feedback data for each relevant mobile station to predict the post-switching MU-MIMO CQIs for that mobile station.

    摘要: Some embodiments of the present disclosure provide for use of a linear chirp signal as a basis for a sensing signal. Modification of the linear chirp signal by a signature function can allow a receiver of the sensing signal to determine an identity for a source of the sensing signal. Accordingly, upon processing the received sensing signal to obtain path parameter estimates, the receiver can direct a transmission of an indication of the path parameter estimates to the source of the sensing signal. Aspects of the present application relate to performing multi-node, multi-path channel estimation on the basis of processing the received sensing signal. Conveniently, the processing is performed with low complexity.
