Abstract  Abstract

PROBLEM TO BE SOLVED: To provide technologies with which additional pilot is adaptively and flexibly transmitted e.g. on the basis of channel conditions and/or other factors in order to achieve good performance.

SOLUTION: A transmitting entity transmits a base pilot in each protocol data unit (PDU). A receiving entity is able to derive a sufficiently accurate channel response estimate of a MIMO channel with the base pilot under nominal (or most of) channel conditions. The transmitting entity selectively transmits an additional pilot if and as needed e.g. on the basis of channel conditions and/or other factors. The additional pilot may be adaptively inserted in almost any symbol period in the PDU. The receiving entity is able to derive an improved channel response estimate with the additional pilot. The transmitting entity sends signaling in order to indicate that additional pilot is being sent. This signaling may be embedded within pilot symbols sent on a set of pilot subbands used for a carrier pilot.
