摘要: An electronic device may include wireless circuitry with a phased antenna array that conveys radio-frequency signals using signal beams of first and second orthogonal polarizations. The array may sweep over a set of signal beam pairs, each including a respective combination of signal beams of the first and second polarizations. The wireless circuitry may gather performance metric values for each of the polarizations and signal beam pairs. The circuitry may generate a filtered set of signal beam pairs by removing signal beam pairs having performance metric values that differ from a maximum of the wireless performance metric values by more than a threshold. The circuitry may select a signal beam pair from the filtered set having a minimum polarization imbalance. The array may concurrently convey first and second wireless data streams using the selected signal beam pair. Minimizing polarization imbalance may maximize overall data throughput for the device.

摘要: Systems and methods performed by user equipment (UE) for communicating over a wireless communication network include receiving data representing one or more communication quality metrics for communication on a New Radio (NR) communication link of the wireless communication network. The method includes determining, based on the data representing the one or more communication quality metrics, a data throughput for the NR communication link of the wireless communication network. The method includes estimating a theoretical throughput for using a Long Term Evolution (LTE) communications link of the wireless network. The method includes comparing the data throughput using the NR communication link to the theoretical throughput for using the LTE communication link. The method includes causing a switch, based on the comparison, from the NR communication link to the LTE communication link.

摘要: A wireless communication device receives an average transmission power limit for a time period, and determines a first MTPL for a first time of the time period by setting the first MTPL to the average transmission power limit. The wireless communication device then transmits a signal at the first time using a first transmission power not to exceed the first MTPL. If the first transmission power is less than the first MTPL, then the wireless communication device determines residual transmission power based on a difference between the first MTPL and the first transmission power. The wireless communication device determines a second MTPL for a second time of the time period by adding the residual transmission power to the first MTPL. The wireless communication device then transmits a signal at the second transmission power not to exceed the second MTPL.

摘要: A wireless device is configured to select a beam and/or an antenna based on detection a detected position and/or orientation of the device relative to a remote device. The device obtains motion data indicating a change in position or orientation of the wireless device. The device determines its pose relative to the remote device. The device accesses a coverage map that associates, for each potential pose for the device with respect to the remote device: an antenna for communicating with the remote device and/or a beam for communicating with the remote device. The device selects a particular antenna and/or a particular beam for communicating with the remote device; and causes transmission or reception of data to or from the remote device by the particular antenna and/or the particular beam.

摘要: A user equipment (UE) passively determines the presence of a cellular network bottleneck in a downlink channel and may take appropriate actions to mitigate the bottleneck. The UE may analyze the transport block size (TBS) of slots of received downlink traffic and assign states the to various slots based on this analysis. Based on these assigned states, the UE may identify a burst of network traffic from network traffic received from the cellular network, and the UE may also determine the burst duration as well as a busy estimation. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the burst duration and the busy estimation.

摘要: In an example method, a first device determines first network resources that have been activated for exchanging data with one or more second devices via a wireless network, and determines, for each of the first network resources, a time duration of a respective burst transmission performed using that first network resource. The first device determines whether to (i) activate second network resources for exchanging data with the second devices and/or (ii) deactivate one or more of the first network resources for exchanging data with the second devices. In response, the first device activates the second network resources and/or deactivates the one or more of the first network resources.

摘要: A system and method for operation of a user equipment (UE) to determine a cellular network bottleneck in a downlink channel, and an apparatus for use in a UE for determining the same. A UE may determine a burst of network traffic from network traffic received from the cellular network during a series of transmission time intervals. The UE may analyze resource allocations to the UE during the burst to determine an extent to which the cellular network is busy. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the analysis of the resource allocations to the UE in the burst.
