Abstract
A data transmission method and apparatus, and storage medium are provided. The method includes: determining, by a layer 3 (L3), data to be transmitted via a medium access control (MAC) link, wherein a quantity of the data to be transmitted is determined such that a data buffer of an MAC function entity meets a transmission rate of the MAC link.
Claims19
A sequence number (SN) switching method for data transmission, performed by a layer 3 user plane (L3 UP), wherein the L3 UP is a function entity in L3, comprising:
- determining data to be transmitted via a medium access control (MAC) link, wherein a quantity of the data to be transmitted is determined such that a data buffer of an MAC function entity meets a transmission rate of the MAC link, the MAC link is an uplink and/or downlink connection link between the L3 UP and the MAC function entity,
- the method further comprises:
- in case that there are multiple MAC links, switching a SN of data to be transmitted via the MAC link when transmitting data,
- when switching the SN of data to be transmitted via the MAC link, a preceding MAC link and a succeeding MAC link corresponding to data of the MAC link are determined according to a received MAC link selection control packet, and the sorting is performed according to the MAC link selection control packet.
A sequence number (SN) switching method for data transmission, applied to a medium access control (MAC) function entity, comprising:
- performing data transmission with a layer 3 user plane (L3 UP) via an MAC link, wherein a quantity of data to be transmitted is determined by the L3 UP, and a quantity of the data to be transmitted is determined such that a data buffer of an MAC function entity meets a transmission rate of the MAC link, the MAC link is an uplink and/or downlink connection link between the L3 UP and the MAC function entity, the L3 UP is a function entity in L3,
- the method further comprises:
- in case that there are multiple MAC links, switching a SN of data to be transmitted via the MAC link by the L3 UP when transmitting data,
- when switching the SN of data to be transmitted via the MAC link, a preceding MAC link and a succeeding MAC link corresponding to data of the MAC link are determined by the L3 UP according to a received MAC link selection control packet, and the sorting is performed by the L3 UP according to the MAC link selection control packet.
