Abstract

An apparatus configured for wirelessly communicating in a wireless communication network includes a wireless interface arrangement having a signal maintenance capability to separate at least one data stream. The apparatus is configured for wirelessly transmitting, to a receiving apparatus, a capability signal having a capability information indicating the signal maintenance capability.

First claim

The invention claimed is:

1. An apparatus comprising a memory having stored therein impairment information indicating an impairment caused from operating a first communication chain or a communication link of the apparatus; and/or
wherein the apparatus is configured for controlling a wireless communication to a further apparatus based on impairment information indicating an impairment caused from operating a first chain of the further apparatus on a second chain of the further apparatus;
wherein the apparatus, is configured to report its effective channel and a corresponding rank, it faces in the wireless communication;
wherein a change in the rank, is based on at least one of:
a change in the effective channel;
an operation mode of the apparatus;
regulatory requirements;
user interaction; or
a property of the device.

2. The apparatus of claim 1 , wherein the apparatus is configured for transmitting the impairment information to a further apparatus.

3. An apparatus configured for wirelessly communicating in a wireless communication network, the apparatus comprising:
a wireless interface arrangement having a signal maintenance capability to separate at least one data stream;
wherein the apparatus is configured for wirelessly transmitting, to a receiving apparatus, a capability signal comprising a capability information indicating the signal maintenance capability; and at least one of:
wherein the signal maintenance capability relates to a device capability forming an upper limit for the communication within the wireless communication network independent from a propagation environment of the apparatus;
wherein the capability information indicates at least a capability of the apparatus to utilize an indicated number of beams transmitted with the wireless antenna arrangement;
wherein the wireless interface arrangement is configured for transmitting a first spatial data stream with a first beam; and for transmitting a second spatial data stream with a second beam, wherein the wireless interface arrangement is configured for separating the first spatial data stream from the second spatial data stream based on the signal maintenance capability;
wherein the apparatus is configured for determining that the signal maintenance capability is changed to a varied signal maintenance capability and to report the varied signal maintenance capability to the receiving apparatus; and
wherein the capability information is device specific for the apparatus; or device class specific for a class of devices to which the device belongs.

4. The apparatus of claim 3 , wherein the apparatus is configured for determining that the signal maintenance capability has changed based on at least one of: an operation mode of the apparatus; or a position of at least a part of a user relative to the apparatus.

5. The apparatus of claim 3 , wherein the apparatus is a UE or an Internet-of-Things device and the capability information relates to an uplink capability of the apparatus.

6. The apparatus of claim 3 , being a base station, wherein the capability information relates to a downlink capability of the apparatus.
