Abstract
A data transmission method, including: learning, by a first wireless network node, a bearer type of a downlink packet; and when the bearer type is a signaling radio bearer SRB, sending, by the first wireless network node, the downlink packet to a second wireless network node, so that the second wireless network node performs a function of a Packet Data Convergence Protocol (PDCP) layer on the downlink packet; or when the bearer type is a data radio bearer DRB, performing, by the first wireless network node, a function of a PDCP layer on the downlink packet, and sending the processed downlink packet to the second wireless network node.
Claims11
A data transmission method, comprising:
- receiving, by a first wireless network node, an uplink packet from a second wireless network node, wherein the uplink packet carries indication information indicating identity of user equipment, information about a bearer type, and identity of a bearer;
- identifying, by the first wireless network node according to the indication information, the user equipment, the bearer type, and the bearer that correspond to the uplink packet;
- and
- performing, by the first wireless network node, a function of a packet data convergence protocol layer on the uplink packet.
A base station, comprising:
- a first wireless network node;
- and
- a second wireless network node;
- wherein the first wireless network node has an radio resource control layer and a packet data convergence protocol layer;
- and
- wherein the second wireless network node has an radio link control layer, a media access control layer, and a physical layer.
A non-transitory computer-readable medium storing instructions that, when executed by a base station, cause the base station to perform operations comprising:
- receiving, by a first wireless network node of the base station, an uplink packet from a second wireless network node, wherein the uplink packet carries indication information indicating an identity of user equipment, information about a bearer type, and an identity of a bearer;
- identifying, by the first wireless network node of the base station according to the indication information, the user equipment, the bearer type, and the bearer that correspond to the uplink packet;
- and
- performing, by the first wireless network node of the base station, a function of a packet data convergence protocol layer on the uplink packet.
A wireless network node comprising:
- at least one processor;
- a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instruct the at least one processor to perform a function of an radio resource control layer and a function of a packet data convergence protocol layer;
- and
- a receiver configured to receive an uplink packet from another wireless network node, wherein the uplink packet carries indication information indicating an identity of user equipment, information about a bearer type, and an identity of a bearer.
A wireless network node comprising:
- at least one processor;
- a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instruct the at least one processor to perform:
- a function of an radio link control layer;
- a function of a media access control layer, and a function of a physical layer;
- and
- a transmitter configured to send an uplink packet to another wireless network node, wherein the uplink packet carries indication information indicating an identity of user equipment, information about a bearer type, and an identity of a bearer.
