Title: Communication method and apparatus
Inventor: LIU FENGXI
IPC: H04L29/08
Filed: 2020-03-17
Abstract: A communication method and apparatus are provided, to resolve a problem that timeliness of data transmission is affected because a communication connection is not established in time. A network protocol stack is deployed for each of a service processing unit and a wireless communication unit in a first communication apparatus. In this way, before the service processing unit enters a working mode, the wireless communication unit may establish a transmission channel with a second communication apparatus based on the deployed network protocol stack. After the service processing unit enters the working mode, the service processing unit exchanges data with the second communication apparatus through the transmission channel based on the deployed network protocol stack. Before the service processing unit enters the working mode, the wireless communication unit enables the transmission channel. Therefore, after entering the working module, the service processing unit may directly use the established transmission channel to exchange the data with the second communication apparatus. This avoids waste of time resources compared with triggering a hole punching process after the service processing unit enters the working mode, and ensures timeliness of data transmission.

Title: Wireless transceiver and method of controlling a wireless transmission
Inventor: RAMIREZ ALEJANDRO
IPC: H04B1/00
Filed: 2021-04-09
Abstract: Embodiments disclosed herein may maximize a transmit power of a wireless transceiver without exceeding limits mandated by a regulatory office. While current practices merely set a transmit gain which is applied for all kinds of possible signal patterns, the embodiments propose to determine the transmit power instead of limiting the transmission to a worst-case scenario. The transmit power may be determined by emulating, simulating, or measuring one or more values by which the transmit power can be derived, whereby further parameters may be taken into account.By raising the average transmit power, the communication signal may be transmitted farther, the obtained data rate may be higher and less packet losses may occur. In general, this may lead to a better usage of a wireless channel.
