A wireless communication method, comprising: transmitting, by a first network node , a first message to a first communication node , the first message including a recommended bit rate for an ongoing communication between the first communication node and a second communication node, wherein the first network node and a second network node are configured to contemporaneously serve the first communication node ; and receiving, by the first network node and in response to the first message, a second message from the first communication node , wherein the second message includes: an acknowledgment indicator indicating that the first communication node accepts the recommended bit rate, or a non-acknowledgment indicator indicating that the first communication node rejects the recommended bit rate, wherein the first network node transmits the first message after receiving a notification message from the second network node, and wherein the notification message informs the first network node that a current bit rate of the first communication node does not meet a quality of service requirement, wherein the notification message includes the recommended bit rate, and a logical channel, LCH, identifier or a data ratio bearer, DRB, identifier, and wherein in response to receiving the non-acknowledgment indicator, the first network node performs any one of: replacing the second network node, deleting a second network node terminated bearer, or coordinating with the second network node to satisfy current bit rate of the first communication node . transmitting, by a first network node , a first message to a first communication node , the first message including a recommended bit rate for an ongoing communication between the first communication node and a second communication node, wherein the first network node and a second network node are configured to contemporaneously serve the first communication node ; and receiving, by the first network node and in response to the first message, a second message from the first communication node , wherein the second message includes: an acknowledgment indicator indicating that the first communication node accepts the recommended bit rate, or a non-acknowledgment indicator indicating that the first communication node rejects the recommended bit rate, an acknowledgment indicator indicating that the first communication node accepts the recommended bit rate, or a non-acknowledgment indicator indicating that the first communication node rejects the recommended bit rate, wherein the first network node transmits the first message after receiving a notification message from the second network node, and wherein the notification message informs the first network node that a current bit rate of the first communication node does not meet a quality of service requirement, wherein the notification message includes the recommended bit rate, and a logical channel, LCH, identifier or a data ratio bearer, DRB, identifier, and wherein in response to receiving the non-acknowledgment indicator, the first network node performs any one of: replacing the second network node, deleting a second network node terminated bearer, or coordinating with the second network node to satisfy current bit rate of the first communication node . replacing the second network node, deleting a second network node terminated bearer, or coordinating with the second network node to satisfy current bit rate of the first communication node . <EOS>
