Embodiment Construction

[0028]As mentioned above, the Rel-17 version has clearly defined the Multi-TRP enhancement for the uplink physical layer uplink shared channel (PhysicalUplink Share Channel, PUSCH) transmission of the URLLC. However, there is no better solution. If the option 4 scheme adopted in Rel-16 is used for Multi-TRP enhancement of PUSCH uplink transmission: K (K>=1) nominal repetition transmissions are configured by the base station, and the initial transmission will be configured for the first nominal repetition The symbol S and the transmission symbol length L, the subsequent K-1 nominal repetition transmissions will be continuously transmitted in the subsequent uplink time slots, and the transmission symbol length is L. If a semi-statically configured downlink symbol or time slot boundary is encountered during transmission of any nominal repetition, it will be divided into one or more actual repetition transmissions.

[0029] Since the enhancement scheme of Rel-16 is applicable to ...

Abstract

A method, device, and device for transmitting uplink data in multiple transceiver nodes, the method comprising: acquiring PUSCH configuration information, the PUSCH configuration information including: nominal number of repeated transmissions, transmission symbol length; according to the nominal number of repeated transmissions And the transmission symbol length, calculate the configured PUSCH transmission total length; calculate the reference parameter according to the division elements appearing in the PUSCH transmission total length, the division elements include at least one of the following: time slot boundary, continuous downlink symbol time period , continuous invalid symbol time period; according to the size relationship between the reference parameter and the nominal number of repeated transmissions, determine the actual repeated transmission segment on the total length of PUSCH transmission; based on the actual repeated transmission segment, perform uplink data on the PUSCH The multi-receiver node switching transmission. The above solution can realize Multi-TRP enhancement of uplink data transmitted by PUSCH.

Description

technical field [0001] Embodiments of the present invention relate to the field of communications, and in particular, to a method, device, and device for controlling uplink data transmission in a multi-transceiver node. Background technique [0002] In the Long Term Evolution (Long Term Evolution, LTE) system, the coordinated multi-point transmission technology is supported as an effective method to improve the user data transmission rate, and is continuously enhanced in subsequent versions of the LTE protocol. [0003] In the standardization process of the New Radio (New Radio, NR), a similar coordinated multi-point transmission technology is called Multi Transport Receive Point (Multi Transport Receive Point, Multi-TRP) transmission. At present, Multi-TRP only enhances the downlink transmission of Ultra-reliable Low Latency Communications (URLLC) and Enhanced Mobile Broadband (EMBB) systems, not URLLC and EMBB systems. The upstream transmission is enhanced. [0004] Curr...
