Embodiment Construction
[0039] Hereinafter, the present invention will be described based on the accompanying drawings. In the following description, some specific embodiments are only for the purpose of description, which should not be construed as any limitation on the present invention, but are only examples. Conventional structures or constructions will be omitted when it may cause to obscure the understanding of the present invention.
[0040] figure 1 is a sequence diagram showing the antenna-related uplink feedback method according to the present invention.
[0041] In step 200, the base station (eNB) may notify the user equipment (UE) which antenna or antennas to perform antenna-related uplink feedback in an implicit or explicit manner.
[0042] (1) implicitly specified
[0043] (a) Alternate designation, which may also be referred to as polling designation, that is, uplink feedback is performed for each antenna / group of antennas in turn. Alternate designation can be sequential or non-seq...
