Embodiment Construction

[0185] For the purposes of simplicity and illustration, the present disclosure has been described primarily with reference to exemplary embodiments thereof. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be readily apparent to those skilled in the art that the present disclosure may be practiced without being limited to these specific details. In this description, well-known methods and structures have not been described in detail so as not to unnecessarily obscure the disclosure.

[0186] This disclosure describes, among other things, techniques for reducing the impact from simultaneously supporting multiple parameter sets. Furthermore, this disclosure describes techniques for measuring CSI more efficiently in systems that support simultaneous use of multiple parameter sets. Furthermore, other desirable features and characteristics of the present disclosure will b...

Abstract

Systems and methods of determining a transmitter or receiver configuration in a wireless communication system are provided. In one exemplary embodiment, a method performed by a radio node (101, 111, 200, 300a-b, 500, 700a-b) in a wireless communication system (100) comprises determining (405) a first transmitter or receiver configuration for transmission or reception in a first frequency spectrum(121) having a first sub-carrier spacing (123) based on a channel information measurement in a second frequency spectrum (131) having a second sub-carrier spacing (133), wherein the first (123) and second (133) sub-carrier spacings are different and the first (121) and second (131) frequency spectrums overlap.

Description

technical field [0001] The present disclosure relates generally to the field of communications, and in particular to determining a transmitter or receiver configuration in a wireless communications system. Background technique [0002] In many wireless communication systems, the availability of channel information (eg, channel quality information, channel state information (CSI), power control information, etc.) is critical for good performance. Channel information may be determined by, for example, estimating the channel state from transmitted reference signals (RS). CSI can then be reported using the estimated channel state. In Long Term Evolution (LTE), CSI typically includes Channel Quality Indicator (CQI), Rank Indicator (RI) and Precoding Matrix Indicator (PMI) values. [0003] The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) system supports a CSI reporting scheme relying on periodically transmitted reference signals. For example, a cell-speci...
