Embodiment Construction

[0039] Some embodiments contemplated herein will now be described more fully with reference to the accompanying drawings. However, other embodiments are within the scope of the subject matter disclosed herein, and the disclosed subject matter should not be construed as limited to only the embodiments set forth herein; rather, these embodiments are provided by way of example to inform the present Those skilled in the art convey the scope of the subject matter.

[0040] Embodiments of the present disclosure use NR reference signals, such as zero-power channel state information reference signals (ZP-CSI-RS), to perform rate matching around LTE signals, especially CRS. NR PDSCH is not mapped to resource elements that transmit reference signals (eg ZP-CSI-RS), see 3GPP TS 38.214, v 15.5.0 clause 5.1.4.2. ZP-CSI-RS is typically configured for rate matching NR PDSCH around other NR signals, such as non-zero power (NZP) CSI-RS for other UEs, and for channel state information interfer...

Abstract

A wireless device is configured to utilize a first carrier for accessing a communication network, the first carrier being implemented according to a first radio-access technology (RAT) and having a first transmission frequency band, the communication network further provides for network access via a second carrier, the second carrier being implemented according to a second RAT and having a second transmission frequency band, the second transmission frequency band at least partially overlaps with the first transmission frequency band. A method performed by the wireless device comprises: receiving a configuration message for the first carrier from a network node, the configuration message comprising an indication of resources in which the wireless device is configured with reference signals according to the first RAT. The resources in which the wireless device is configured with reference signals according to the first RAT are defined to enable mapping of resources for a data channel on the first carrier around one or more signals transmitted on the second carrier according to the second RAT.

Description

technical field [0001] Embodiments of the present disclosure relate to wireless communications, and in particular to methods, devices and machine-readable media for configuration of reference signals in wireless communications networks. Background technique [0002] Generally, all terms used herein are to be interpreted according to their ordinary meaning in the relevant technical field, unless a different meaning is explicitly given and / or implied from the context in which it is used. Unless expressly stated otherwise, all references to a / an / the element, device, component, part, step, etc., are to be construed openly as referring to at least one instance of the element, device, component, part, step, etc. . The steps of any method disclosed herein do not have to be performed in the exact order disclosed, unless a step is explicitly described as being after or before another step and / or where an implied step must be after or before another step. Any feature of any embodime...
