TECHNICAL FIELD

This disclosure is directed generally to digital wireless communications.

BACKGROUND

Mobile telecommunication technologies are moving the world toward an increasingly connected and networked society. In comparison with the existing wireless networks, next generation systems and wireless communication techniques will need to support a much wider range of use-case characteristics and provide a more complex and sophisticated range of access requirements and flexibilities.

Long-Term Evolution (LTE) is a standard for wireless communication for mobile devices and data terminals developed by 3rd Generation Partnership Project (3GPP). LTE Advanced (LTE-A) is a wireless communication standard that enhances the LTE standard. The 5th generation of wireless system, known as 5G, advances the LTE and LTE-A wireless standards and is committed to supporting higher data-rates, large number of connections, ultra-low latency, high reliability and other emerging business needs.

SUMMARY

Techniques are disclosed for a bit rate adjustment process with a feedback. For instance, in embodiments involving a dual connectivity scenario, the RAN side can coordinate the bit rate at the UE side. Further, in embodiments involving a single-connection scenario, a feedback mechanism can be added to better run the process of adjusting the bit rate.

In one exemplary aspect, a wireless communication method is disclosed. The method includes performing communication of a first message between a first communication node and a first network node. The first message includes a recommended bit rate for an ongoing communication between the first communication node and a second communication node. The first network node and a second network node are configured to contemporaneously serve the first communication node. In some embodiments, the exemplary method further includes performing communication of a second message between the first communication node and the first network node in response to the first message. 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.

In some embodiments, the first network node transmits the first message to the first communication node, and the first network node receives the second message from the first communication node. In some embodiments, 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. In some embodiments, the notification message includes the recommended bit rate, and a logical channel (LCH) identifier or a data radio bearer (DRB) identifier. In some embodiments, 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.

In some embodiments, the first communication node receives the first message from the first network, and the first communication node transmits the second message to the first network node. In some embodiments, the first communication node negotiates acceptability of the recommended bit rate with the second communication node prior to transmitting the second message to the first network node.

In some embodiments, the first and second messages further include a set of identifiers from any one of a first set of identifiers that include a logical channel (LCH) identifier and a first network node indicator or a second network node indicator, a second set of identifiers that include the LCH identifier and a cell group identifier, or a third set of identifiers that include a data radio bearer (DRB) identifier. In some embodiments, the first and second messages include Medium Access Control Control Elements (MAC CEs). In some embodiments, the first communication node includes a first user equipment, the second communication node includes a second user equipment or a multimedia terminal, the first network node includes a master radio access network (RAN) node, and the second network node includes a secondary RAN node.

In yet another exemplary aspect, the above-described method is embodied in the form of processor-executable code and stored in a computer-readable program medium.

In yet another exemplary embodiment, a device that is configured or operable to perform the above-described methods is disclosed.

The above and other aspects and their implementations are described in greater detail in the drawings, the descriptions, and the claims.
