Embodiment Construction

[0040] In practical applications, the signal vector received by the user terminal on the kth resource element (Resource Element, RE) is r k , r k It can be expressed as the following formula (1):

[0041]

[0042] In formula (1), Expressed as the effective channel matrix corresponding to the serving cell corresponding to the kth RE, the effective channel matrix includes the actual channel matrix and the precoding matrix; is the signal of the serving cell corresponding to the kth RE; Expressed as the effective channel matrix corresponding to the interfering cell corresponding to the kth RE; is the signal of the interfering cell corresponding to the kth RE; n k is the noise signal corresponding to the kth RE, and n k for the variance The additive noise vector of the independent and identically distributed complex Gaussian elements of ; 1≤k≤K, K is the number of REs required to perform blind detection and estimation of interfering cells.

Abstract

The invention discloses user equipment, a service cell demodulation method, a storage medium and electronic equipment. The method comprises steps: all resource elements corresponding to the current symbol on the current physical resource block are traversed; an interference cell parameter corresponding to the current symbol on the current physical resource block is determined; and according to thedetermined interference cell parameter, the demodulation logarithmic likelihood ratio of the service cell corresponding to the current symbol on the current physical resource block is calculated. Theabove scheme can reduce the data storage space occupied by demodulation of the service cell.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a user terminal, a demodulation method for a serving cell, a storage medium, and electronic equipment. Background technique [0002] 3GPP has introduced the Network Assisted Interference Cancellation and Suppression (NAICS) technology, and the base station sends the interfering cell parameters to the user terminal through broadcast, dedicated signaling or downlink control information (Downlink Control Information, DCI). The interfering cell parameters include a rank indicator (Rank Indicator, RI), a precoding matrix indicator (Pre-coding Matrix Indicator, PMI) and a modulation type (Modulation, MOD) of a neighboring cell. Under the condition that the parameters of the interfering cell are known, the user terminal (User Equipment, UE) performs corresponding processing operations on the received signal, which can significantly improve the performance of the communicati...
