Embodiment Construction

[0056] The technical solution in this application will be described below with reference to the accompanying drawings.

[0057] In order to solve the problem that the downlink control information DCI in the prior art does not support the requirement that multiple TPs need scheduling resources respectively. The embodiment of this application is based on figure 1 (a) in or figure 1 The communication system shown in (b) in (b) proposes a transmission method that can meet the requirement of one DCI to schedule resources of multiple TPs, that is, multiple groups of scheduled resources.

[0058] Such as figure 1 (a) and figure 1 As shown in (b), the embodiment of the present application provides a communication system 100 . The communication system 100 includes at least two network devices and at least one terminal. A terminal accesses a network device through a wireless interface to communicate, and can also communicate with another terminal, such as communication in a device-...

Abstract

The present application provides a transmission method, a terminal and a network device, capable of scheduling multiple groups of scheduling resources through one DCI, and meeting the requirements of the network device for scheduling resources of multiple TPs or multiple groups of non-QCL antenna ports. The method includes: the terminal receives downlink control information DCI sent by the network device, the DCI is used to indicate target scheduling resources, the target scheduling resources include M groups of scheduling resources, and M is an integer greater than or equal to 2, wherein the M groups of scheduling resources Corresponding to M groups of antenna ports that are not quasi-co-location (QCL), each group of antenna ports in the M groups of antenna ports includes at least one antenna port; the terminal determines the M groups of scheduling resources according to the DCI.

Description

technical field [0001] The present application relates to the communication field, and more specifically, relates to a transmission method, a terminal and a network device. Background technique [0002] Coordinated multipoint transmission (coordinated multipoint transmission, CoMP) is a method for solving the inter-cell interference problem and improving the throughput of a cell edge user equipment (user equipment, UE). In the CoMP technology, multiple adjacent cells can jointly process or coordinate edge users to avoid interference and improve edge user throughput. The downlink CoMP technology mainly includes joint transmission (joint transmission, JT), coordinated scheduling and beamforming (CS / CB), dynamic point selection / dynamic point blanking (dynamic point selection / dynamic point blanking, DPS / DPB), etc. In cooperative transmission modes such as DPS, DPB, and CS / CB, a single transmission point (transmission point, TP) serves the UE, while in JT, multiple cooperative T...
