Title:
METHOD AND DEVICE FOR UPLINK TRANSMISSION RESOURCE INDICATION
Document Type and Number:
WIPO Patent Application WO/2021/238504
Kind Code:
A1
Abstract:
Provided in the present application are a method and device for uplink transmission resource indication, related to the technical field of communications, and used for solving the problem of uplink transmission resource wastage found in the prior art, also for avoiding for some nodes in a heterogeneous network, when simultaneously receiving a downlink transmission of a network device and an uplink transmission of a UE, a collision between a downlink CSI-RS and an uplink DMRS of uplink data. The method is applicable in a first network device and comprises: determining a first RS resource of a second network device in a time-frequency resource, the RS may be a CSI-RS, the time-frequency resource comprising multiple time units in a time domain, each time unit may be one slot, the first RS resource being located at the first time unit in the time domain, and the multiple time units comprising the first time unit; and transmitting first configuration information to a UE, the first configuration information being used for determining an uplink transmission resource in the time-frequency resource, the uplink transmission resource may refer to a resource used for transmitting uplink information, and the uplink transmission resource not overlapping the first RS resource.
