Electronic apparatus, wireless communication method and computer-readable medium

Abstract

The present disclosure relates to an electronic apparatus, a wireless communication method, and a computer-readable medium. According to one embodiment, an electronic apparatus used at a base station side comprises a processing circuit. The processing circuit is configured to carry out control so as to carry out multiple-input multiple-output transmission by means of two or more transmitting and receiving points, and to send indication information to a user equipment, wherein the indication information is related to a scheme of mapping between a spatial multiplexing layer and a code word for transmission by means of two or more transmitting and receiving points.

1 . An electronic apparatus for a user equipment, comprising:
 processing circuitry configured to
 determine, based on a downlink channel state of a Multi-Input Multi-Output transmission, a mapping scheme between spatial multiplexing layers and code words transmitted through two or more transmission/reception points; and 
 send indication information related to the mapping scheme to a base station, 
   wherein   the user equipment keeps wireless communication with the two or more transmission/reception points.   
     
     
         2 . The electronic apparatus according to  claim 1 , wherein
 the mapping scheme is used for uplink transmission.   
     
     
         3 . The electronic apparatus according to  claim 1 , wherein
 the processing circuitry is configured to perform control to receive the Multi-Input Multi-Output transmission performed by the base station through the two or more transmission/reception points.   
     
     
         4 . The electronic apparatus according to  claim 1 , wherein
 the indication information comprises a rank index for each of the two or more transmission/reception points.   
     
     
         5 . The electronic apparatus according to  claim 4 , wherein
 the indication information further comprises a bitmap, and   a length of the bitmap is a sum of the rank indices of the two or more transmission/reception points.
