1. A device-to-device relay processing method, comprises:
comparing, by a first device, a parameter included in a channel quality information of direct links between the first device and at least two second devices with a threshold value corresponding to the parameter to determine a processing manner for a device-to-device relay function, wherein the processing manner comprises activating the device-to-device relay function or deactivating the device-to-device relay function;
wherein the parameter of the channel quality information comprises a first-type parameter and/or a second-type parameter, wherein:
the first-type parameter comprises one or more of: Channel State Information, CSI; Received Signal Strength Indication, RSSI; Reference Signal Receiving Power, RSRP; or Reference Signal Receiving Quality, RSRQ;
the second-type parameter comprises one or more of: a block error rate or a bit error rate;
wherein in a case of that the parameter of the channel quality information comprises the first-type parameter; and the comparing, by the first device, the parameter included in the channel quality information of the direct links between the first device and the at least two second devices with the threshold value corresponding to the parameter to determine the processing manner for the device-to-device relay function, comprises:
in response to the direct links being unidirectional direct links, measuring, by the first device, a first-type parameter of channel quality information of signals sent by the at least two second devices through the direct links with the at least two second devices; and determining that the processing manner is activating the device-to-device relay function in response to the first device not activating the device-to-device relay function and a duration in which measured first-type parameter of the channel quality information of the at least two direct links is higher than the threshold value corresponding to the parameter reaches a set duration; and/or
in response to the direct links being bidirectional direct links: measuring, by the first device, a first-type parameter of channel quality information of signals sent by the at least two second devices through the direct links with the at least two second devices, and receiving measurement reports sent by the at least two second devices through the direct links, wherein each of the measurement reports contains a first-type parameter of channel quality information obtained by a corresponding second device measuring a signal sent by the first device; and
determining that the processing manner is activating the device-to-device relay function in response to the first device not activating the device-to-device relay function, a duration in which measured first-type parameter of the channel quality information of the at least two direct links is higher than the threshold value corresponding to the parameter reaches a set duration, and a duration in which the first-type parameter contained in the measurement reports received through the at least two direct links is higher than the threshold value corresponding to the parameter reaches the set duration;
wherein in a case of that the parameter of the channel quality information comprises the second-type parameter; and the comparing, by the first device, the parameter included in the channel quality information of the direct links between the first device and the at least two second devices with the threshold value corresponding to the parameter to determine the processing manner for the device-to-device relay function, comprises:
in response to the direct links being unidirectional direct links: measuring, by the first device, a second-type parameter of channel quality information of signals sent by the at least two second devices through the direct links with the at least two second devices; and determining that the processing manner is activating the device-to-device relay function in response to the first device not activating the device-to-device relay function and a duration in which the measured second-type parameter of the channel quality information of the at least two direct links is lower than the threshold value corresponding to the parameter reaches a set duration; and/or
in response to the direct links being bidirectional direct links: measuring, by the first device, a second-type parameter of channel quality information of signals sent by the at least two second devices through the direct links with the at least two second devices, and receiving measurement reports sent by the at least two second devices through the direct links, wherein each of the measurement reports contains a second-type parameter of channel quality information obtained by a corresponding second device measuring a signal sent by the first device; and determining that the processing manner is activating the device-to-device relay function in response to the first device not activating the device-to-device relay function, a duration in which the measured second-type parameter of the channel quality information of the at least two direct links is lower than the threshold value corresponding to the parameter reaches a set duration, and a duration in which the second-type parameter contained in the measurement reports received through the at least two direct links is lower than the threshold value corresponding to the parameter reaches the set duration.
