  • Patent number: 11363574
    Abstract: An information transmission method, is provided, including, a terminal determines attribute information of uplink information based on a beam identifier, and sends the uplink information to a network side device based on the attribute information. After receiving the uplink information, the network side device determines the beam identifier based on the uplink information. In this process, the terminal implicitly indicates beam IDs of different selected beams by using attribute information of reported uplink information. Different beams correspond to different attribute information of the uplink information. In other words, each beam corresponds to specific attribute information of the uplink information. Implicitly indicating a beam ID to the network side device reduces LTE standardization complexity and reduces signaling overheads.

  • Patent number: 11190252
    Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. For example, a user equipment (UE) device within a wireless communication system may select a desired number of antenna elements for receiving a communication from another device based on a channel quality determination. The UE receives a first signal from a transmitting device using a first beam. The UE determines a channel quality metric and compares the channel quality metric with a channel quality threshold. The UE adjusts a number of antenna elements used for beamformed wireless communication between the transmitting device and the UE based on the comparison between the channel quality metric and the channel quality threshold. Based on this adjustment, the UE receives a second signal from the transmitting device using a second beam that has a different number of antenna elements than the first beam.
