Abstract
A technique, including transmitting data and/or control information; and transmitting common phase error and/or inter carrier interference correction reference signal, wherein said common phase error and/or inter carrier interference correction reference signal occupies a variable amount of radio resources.
Claims20
A method comprising:
- receiving a radio transmission including at least one of data and control information, and at least one common phase error reference signal multiplexed with the at least one of data and control information;
- receiving information indicating a structure of said at least one common phase error reference signal from a set of possible structures;
- and
- performing common phase error correction using the received at least one common phase error reference signal on the at least one of data and control information,
- wherein the at least one common phase error reference signal occupies one or more radio resources in accordance with an adaptive reference signal structure, and wherein said at least one common phase error reference signal is included because said transmission of said at least one of data and control information uses a modulation and coding scheme having an order of complexity above a predetermined threshold.
2 more elements
An apparatus comprising:
- at least one processor;
- and
- at least one non-transitory memory including computer program code, wherein the memory and computer program code are configured, with the processor, to cause the apparatus to:
- receive a radio transmission including at least one of data and control information, and at least one common phase error reference signal multiplexed with the at least one of data and control information;
- receive information indicating a structure of said at least one common phase error reference signal from a set of possible structures;
- and
- perform common phase error correction using the received at least one common phase error reference signal on the at least one of data and control information,
- wherein the at least one common phase error reference signal occupies one or more radio resources in accordance with an adaptive reference signal structure, and wherein said at least one common phase error reference signals is included because said transmission of said at least one of data and control information uses a modulation and coding scheme having an order of complexity above a predetermined threshold.

A method comprising:
- receiving a radio transmission including at least one of data and control information, and at least one of common phase error and inter-carrier interference correction reference signals multiplexed with the at least one of data and control information;
- receiving information indicating a structure of said at least one of common phase error and inter-carrier interference correction reference signals from a set of possible structures;
- and
- performing at least one of common phase error correction and inter-carrier interference correction using the received at least one of common phase error and inter-carrier interference correction reference signals on the at least one of data and control information,
- wherein the at least one of common phase error and inter-carrier interference correction reference signals occupies one or more radio resources in accordance with an adaptive reference signal structure, and wherein said at least one of common phase error and inter-carrier interference correction reference signals is included because said transmission of said at least one of data and control information uses a modulation and coding scheme having an order of complexity above a predetermined threshold.
