There is provided a method comprising, in an antenna array comprising a plurality of antenna elements for use in a multiple-input multiple-output system, using at least one receiver for reception of at least one first signal by at least one of the plurality of antenna elements and using at least one first transceiver for at least one of transmission and reception of at least one second signal by at least one of the plurality of antenna elements, wherein the at least one receiver operates using at least one of a lower accuracy and a narrower bandwidth relative to the at least one first transceiver.

Method, system and apparatus

An apparatus and a apparatus method for controlling transmissions of base stations are proposed. In the method, the apparatus belongs to a set of apparatuses controlled by a common controller, transmits at least one control signal unique to the apparatus within a given area and transmits also a second control signal common to a set of apparatuses controlled by the same controller.

Controlling transmissions

Disclosed is a method to operate a wireless user equipment, a wireless user equipment, a computer program product, and an apparatus. The method includes, in response to operation during a Baseline Procedure when no absolute grant (AG) is received from a wireless network node, determining if there was a scheduled transmission in a previous transmission time interval of a hybrid automatic repeat request (HARQ) process and, if there was, using a serving relative grant (SRG) and, if it is determined instead that there was not a scheduled transmission in the previous transmission time interval of the HARQ process, not using the SRG if it is determined that there was a scheduling information (SI) event alone in the previous transmission time interval of the HARQ process.

Apparatus, method and computer program product providing user equipment operation by considering scheduling information with regard to the use of relative grants
