Abstract
A method (300) for transmitting pilots in a multi-output communication system - multiple inputs, MIMO, comprising: transmitting (310) in each protocol data unit, PDU, of a physical layer a first 5 pilot suitable for derive an estimate of a response from a MIMO channel between a transmitting entity and a receiving entity; selectively transmit (322) in each PDU an additional pilot suitable to derive an improved estimate of the response of the MIMO channel; and transmit (320) signaling to indicate that the additional pilot is being transmitted; wherein the additional pilot is sent in a first set of frequency subbands in a symbol period selected for the transmission of additional pilots, and in which the signaling is sent at the same time as the additional pilot for a second set of subbands of frequency in the symbol period.
