Title:
INFORMATION DETERMINATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/027898
Kind Code:
A1
Abstract:
Disclosed are an information determination method and apparatus, relating to the field of communications and used for ensuring that overhead of time-frequency resources is not increased when a network device indicates parameters, such as frequency domain resources, RVs and MCSs, used by two TRPs. The information determination method comprises: receiving first indication information, second indication information and downlink control information (DCI) from a network device, wherein the first indication information is used for indicating the maximum number of codewords that can be scheduled by individual DCI, and the second indication information is used for indicating a data transmission mode; and if it is determined, according to the first indication information, that a first condition is met, and it is determined, according to the second indication information, that a second condition is met, determining, from the DCI, a first set of transmission parameter fields corresponding to first data and a second set of transmission parameter fields corresponding to second data, wherein an MCS field of the second data or the MCS field and an NDI field of the second data is used for indicating one of the following pieces of information or a combination of more than one of the following pieces of information: a modulation order used by the second data, a code rate used by the second data, and frequency resource information of the second data.
