[0104] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), Super 3G, IMT-Advanced, 4th Generation Mobile Communication System (4G), 5G, 5G New Radio (NR), 6G, Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Ultra-Wideband (UWB), Bluetooth, and public terrestrial mobile communication networks. Land Mobile Networks (PLMNs), device-to-device (D2D) systems, machine-to-machine (M2M) systems, Internet of Things (IoT) systems, vehicle-to-everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0105] In some embodiments, CA can be divided into continuous CA and discontinuous CA. For continuous CA, the terminal only needs one transceiver; while for different frequency bands of discontinuous CA, different radio frequency chains (RF chains) are required. Therefore, in the power-saving features of Release 16, different discontinuous reception (DRX) packets can be set according to the different RF chains used by the terminal.

[0106] In some embodiments, as shown in FIG1B, which is a schematic diagram of a DRX cycle according to an exemplary embodiment, different DRX groups use a set of DRX parameters, such as using different onDurationTimers and DRX inactivity Timers. However, the onDurationTimers are aligned. This is because DRX group 1 is typically used for FR1, and DRX group 2 is used for FR2, i.e., for low-frequency and high-frequency bands respectively. According to the 3rd Generation Partnership Project (3GPP) definition of the frequency range of 5G communication technology, FR1 is 450MHz-6000MHz, and FR2 is 24250MHz-52600MHz. Since the higher frequency band has a higher data rate, the same amount of data is transmitted faster on FR2. Therefore, the onDurationTimer and DRX inactivity Timer on FR2 are configured to be shorter than those on FR1. All other parameters are the same.

[0107] In some embodiments, the power-saving features in Release 16 can configure different DRX groups based on the different RF links used by the terminal. In the dual DRX feature, the two transceivers are essentially the same from a hardware implementation perspective, supporting the same RF and baseband bandwidth. Dual DRX is designed for high traffic volumes and increased speeds. However, this approach leads to a significant increase in the terminal's power consumption.

[0108] In some embodiments, from a power-saving perspective, for small data transmissions, the terminal can be designed to operate on a transceiver with lower hardware capabilities, meaning it supports smaller RF and baseband bandwidths, thus only requiring minimal data transmission and reception. Later, when large data transmissions are needed, the terminal can operate on a transceiver with larger RF and baseband bandwidths, or both simultaneously, depending on the business requirements.

[0109] To this end, embodiments of this disclosure propose a communication method, communication device, communication system, storage medium, and program product. By introducing a transceiver working mechanism that meets minimum data transmission and reception functions, the transceiver used by the terminal during data transmission can be flexibly switched, thereby reducing the terminal's power consumption without affecting data transmission. This further saves the terminal's power.

For example, it supports greater bandwidth, more MIMO layers, and higher peak rates. In addition, the second transceiver supports CA or DC and AI and other service capabilities.

[0357] For the second transceiver, it can be agreed that its supported service capabilities must at least meet specific wireless communication capabilities.

[0358] As an example, the prerequisite for the second transceiver to support AI capabilities is that specific wireless communication capabilities must be met, such as a supported bandwidth of at least X MHz and a supported peak rate of Y bps.

[0359] Example 6, working mode 1, the first transceiver and the second transceiver work alternately.

[0360] In some embodiments, the terminal operates using a first transceiver under specific conditions, then switches to operating using a second transceiver, and then falls back to operating using the first transceiver.

[0361] In some embodiments, the specific conditions under which the first transceiver operates can be determined by the state of the terminal. In one embodiment, the terminal is in an RRC disconnected state and operates using the first transceiver. When the terminal enters an RRC connected state, it switches to operating using the second transceiver. When the terminal enters an RRC disconnected state again, it falls back to operating using the first transceiver.

[0362] In some embodiments, the specific conditions under which the first transceiver operates can be determined by the terminal's rate requirements. In one embodiment, when the terminal's rate requirements are low, the terminal operates using the first transceiver; when the terminal's rate requirements are high, the terminal switches to operating using the second transceiver. If the terminal has no data transmission for a period of time or the terminal's rate requirements decrease, the terminal reverts to operating using the first transceiver.

[0363] In some embodiments, the first transceiver may be in sleep mode while the second transceiver is in operation.

[0364] In some embodiments, the terminal can pre-start the second transceiver by giving it a warm start power-on before the second transceiver starts working.

[0365] In some embodiments, the first transceiver is in hibernation, meaning that the terminal can use the first transceiver to perform a small number of tasks, such as relaxed measurements, without data transmission, etc.

[0366] In some embodiments, the first transceiver is in a sleep state, and the terminal can use the first transceiver to assist the second transceiver in performing inter-frequency measurements, thereby reducing data interruptions to the second transceiver.

[0367] Example 7: The network can instruct the terminal whether to use the first transceiver or the second transceiver.

[0368] In some embodiments, the network instructs the terminal to operate the second transceiver at a predetermined time, while the first transceiver goes into hibernation.

[0369] In some embodiments, the network instructs the terminal to operate the second transceiver at a predetermined time point after receiving the transceiver switching instruction, while the first transceiver goes into hibernation.

[0370] In some embodiments, the network may use RRC signaling, MAC signaling, Lay1 signaling, or other methods to notify the terminal to switch transceivers.

[0371] Example 8, Working mode 2, the first transceiver and the second transceiver work simultaneously.

[0372] In some embodiments, the first transceiver only has the ability to receive and decode PDCCH. After the terminal listens to the PDCCH based on the first transceiver, the terminal will wake up the second transceiver to receive and decode PDSCH.

[0373] In some embodiments, the second transceiver is in a sleep state until it is woken up.

[0374] Example 9, Terminal Capability Definition

[0375] In some embodiments, some terminals may have only a first transceiver. In some embodiments, some terminals may have only a second transceiver. In some embodiments, a terminal may have both a first transceiver and a second transceiver.

[0376] In some embodiments, the terminal operates using a first transceiver before reporting its capabilities to the network. The terminal reports its capabilities to the network, informing the network that it has both a first and a second transceiver, so that the network can instruct the terminal to perform a transceiver switch at an appropriate time.

[0377] In some embodiments, a terminal may report its capabilities to the network via an RRC message or an early indication method.
