Base station side device and method for wireless communication, and user side device and method for wireless communication
First Claim
1. A device at a base station side for wireless communications, comprising:
- circuitry configured to;
determine dynamically, based on transmission characteristics related to a user equipment, a reference signal and an associated resource element to be used by the user equipment from a set of available reference signals and resource elements of the base station; and
generate reference signal configuration information for the user equipment, with the configuration information containing an indication of a sequence number of a combination of the reference signal and the associated resource element to be used by the user equipment,wherein the sequence number of the combination of the reference signal and the associated resource element is associated with a sequence number of an antenna port, and each antenna port is configured to transmit a different combination of reference signal and associated resource element, andwherein the circuitry is configured to generate a bitmap based on the sequence number of the combination of the reference signal and the associated resource element to be used by the user equipment, with each bit of the bitmap representing whether a combination of a reference signal and an associated resource element corresponding to the bit is to be used by the user equipment.

Abstract
The disclosure provides a base station side device and method for wireless communication, and a UE side device and method for wireless communication. The base station side device for wireless communication includes: a determination unit configured to dynamically determine, on the basis of a transmission characteristic relevant to a user equipment, a reference signal to be used by the user equipment from a reference signal set available for a base station; and a generation unit configured to generate reference signal configuration information for the user equipment, wherein the configuration information includes an indication for indicating the sequence number of the reference signal to be used by the user equipment, and the sequence number of the reference signal is relevant to the sequence number of an antenna port.
