Communication method and apparatus for adjusting communication parameter bias
The filed patent (Publication Number: US20230319615A1) describes a communication method performed by a network device and a terminal. The method involves determining a bias and a threshold of a communication parameter and sending this information.
In the communication method performed by the network device (claim 13), the bias of the communication parameter corresponds to a first-type terminal, and the threshold corresponds to a second-type terminal. The bias is determined based on a minimum communication parameter measurement value allowed for the first-type terminal to access the network device. The capability of the first-type terminal is lower than that of the second-type terminal, and this capability includes factors such as terminal transceiver bandwidth, number of transceiver antennas, maximum number of bits in a transport block, and processing time delay.
The communication parameter in this method is the reference signal received power (RSRP). The bias and threshold of the communication parameter are determined through configuration information of remaining minimum system information (RMSI), which includes a bias information field indicating the bias.
In the communication method performed by the terminal (claim 19), the terminal acquires the bias and threshold of the communication parameter and conducts communication based on the measurement value of the communication parameter, the bias, and the threshold. Similar to the network device method, the bias of the communication parameter corresponds to a first-type terminal, and the threshold corresponds to a second-type terminal. The bias is determined based on a minimum communication parameter measurement value allowed for the first-type terminal to access the network device. The capability of the first-type terminal is lower than that of the second-type terminal, and this capability includes factors such as terminal transceiver bandwidth, number of transceiver antennas, maximum number of bits in a transport block, and processing time delay.
The communication apparatus for the network device (claim 45) includes a processor and memory. The processor is configured to determine the bias and threshold of the communication parameter and send this information. The bias of the communication parameter corresponds to a first-type terminal, and the threshold corresponds to a second-type terminal. The bias is determined based on a minimum communication parameter measurement value allowed for the first-type terminal to access the network device. The capability of the first-type terminal is lower than that of the second-type terminal, and this capability includes factors such as terminal transceiver bandwidth, number of transceiver antennas, maximum number of bits in a transport block, and processing time delay. The communication parameter in this apparatus is the reference signal received power (RSRP), and the bias and threshold are determined through configuration information of remaining minimum system information (RMSI), which includes a bias information field indicating the bias.
The communication apparatus for the terminal (claim 52) includes a processor and memory. The processor is configured to perform the communication method described in claim 19, which involves acquiring the bias and threshold of the communication parameter and conducting communication based on the measurement value of the communication parameter, the bias, and the threshold.
