Systems and methods are disclosed herein for enabling a User Equipment (UE) to perform cell quality derivation in a wireless communication network utilizing parameters from an appropriate measurement object. In some embodiments, a method of operation of a UE to perform cell quality derivation in a wireless communication network comprises obtaining parameters to perform cell quality derivation for a serving cell of the UE from a measurement object that contains frequency information that matches frequency information provided in a serving cell configuration of the serving cell.

In this manner, the UE is enabled to perform cell quality derivation using parameters from an appropriate measurement object.

According to a communication method of the present disclosure, a responder, after the end of transmission sector sweep (TXSS), receives from an initiator a first feedback frame including a BF training type FIELD indicating whether or not to implement a beam forming training (BFT) of a single user multi-input multi-output (SU-MIMO). If the BF training type FIELD indicates that a BFT of the SU-MIMO is to be implemented, the responder transmits to the initiator a second feedback frame based on the result of the TXSS and including a signal to noise ratio (SNR) and a sector identifier (ID) order. The initiator implements the BFT of the SU-MIMO between the initiator and the responder on the basis of the SNR and the sector ID order.

A terminal according to one aspect of the present disclosure includes a control section that assumes that, when a sounding reference signal (SRS) resource set including a plurality of SRS resources respectively corresponding to the different numbers of SRS ports is configured, parameters for respective SRS resources are configured independently, and a transmitting section that transmits an SRS by using at least one of the plurality of SRS resources. According to one aspect of the present disclosure, it is possible to appropriately control UL transmission.
