or the UE receives an uplink configuration message sent by the second base station, and the message indicates that the information on PUCCH, PUSCH and PRACH which are originally transmitted by the second base station uplink on the second base station side of the current UE can be transmitted by the first base station side uplink.
And the first base station or the second base station sends uplink configuration information to the UE and indicates the UE to transmit uplink information through the first base station in an uplink mode.
The first base station can be L TE base station, the second base station can be NR base station, and both L TE base station and NR base station can be MN master node base station under NSA network architecture.
The UE can convert the generated uplink message from the second base station side uplink to the first base station side uplink for transmission according to the existing rule; the UE may not respond to the uplink configuration message sent by the base station.
The base station issues an uplink configuration message of the UE, which can be a downlink reconfiguration message and indicates the UE to switch the link; or RAR message, indicating at which base station the other uplink message (e.g. MSG3) is sent on uplink;
the base station sends down the uplink configuration message of the UE, which can comprise scheduling message for allocating time-frequency resources for NR uplink information of the UE on L TE, indication message for sending reporting modes of different data by the UE, and the like;
the uplink message may include: physical layer feedback messages, physical layer indication messages, MAC layer control messages, RRC messages, etc.
The method for transmitting the uplink message by the UE can comprise the steps that for the NR uplink message with high timeliness, the NR uplink message can be transmitted preferentially in all L TE and NR messages and data, for example, the scheduling priority is set to be the highest;
marking the NR uplink message with a mark, wherein the mark can identify whether the message is the NR uplink message, whether the message is a message with higher timeliness, and the like, and assist the UE in data transmission;
an independent 5QI can be set for the NR uplink message and transmitted on L TE PUSCH;
l TE base station can reserve independent time frequency resource for NR uplink message, which is specially used to transmit NR uplink message, and configure in RRC reconfiguration message.
If a timer exists between the sending and receiving of the uplink message, the first base station or the second base station can prolong the timer for a certain time.
The L TE uplink transmission scheme may be transmission on the PUCCH of the first base station, or transmission on the PUSCH of the first base station.
The link conversion target may be any uplink channel, or may perform conversion transmission for a PHY, a MAC layer, or the like.
When the first base station is L TE base station and the second base station is NR base station, the UE receives the uplink configuration message, the UE converts the uplink message into L TE uplink transmission, and the UE schedules the transmission of the uplink message according to the priority.
