Title:
METHOD AND APPARATUS FOR DETERMINING RELATIONSHIP BETWEEN PTRS PORTS AND DMRS PORTS, MEDIUM AND PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/185490
Kind Code:
A1
Abstract:
The present disclosure discloses a method and apparatus for determining a relationship between PTRS ports and DMRS ports, a medium, and a product, relating to the field of communications. The method comprises: when a target layer mapping scheme corresponding to a number n of CWs is used, determining an association relationship between an uplink PTRS port and an uplink DMRS port on the basis of DCI, a maximum number of uplink DMRS ports being 8, a value of n being 1 or 2, and the target layer mapping scheme being a layer mapping scheme of type 1 or a layer mapping scheme of type 2. The method is used to support implementation of related functions of uplink PTRS ports and uplink DMRS ports corresponding to 8 antenna ports under different layer mapping schemes.
