Abstract

Embodiments herein relate to a radio arrangement for enabling communication in a wireless communication network, wherein the radio arrangement comprises at least two signal path configurations for transmitting and/or receiving signals to and/or from a radio device in the wireless communication network. The radio arrangement comprises a radio apparatus and an antenna arrangement connected to the radio apparatus. The radio arrangement is configured to obtain, at the radio apparatus, an indication, which indication is indicating a configuration of the antenna arrangement connected to the radio apparatus. The radio arrangement is further configured to select, for communication in the wireless communication network, a signal path configuration at the radio apparatus and/or the antenna arrangement of the at least two signal path configurations based on the obtained indication.

First claim

The invention claimed is:

1. A radio arrangement for enabling communication in a wireless communication network, wherein the radio arrangement comprises at least two signal path configurations for transmitting and/or receiving signals to and/or from a radio device in the wireless communication network, a radio apparatus and an antenna arrangement connected to the radio apparatus, the radio arrangement being configured to:
obtain, at the radio apparatus, an indication over a separate notification connection, which indication is at least one of: a non connection; a known resistor value; a known voltage; and a ground connection, and is indicating a configuration of the antenna arrangement connected to the radio apparatus; and
select, for communication in the wireless communication network, a signal path configuration at the radio apparatus and/or the antenna arrangement of the at least two signal path configurations based on the obtained indication.

2. The radio arrangement according to claim 1 , wherein the radio arrangement is configured to alter the signal path configuration in the radio apparatus and/or in the antenna arrangement based on one or more radio parameters, which radio parameter is at least one of the following: supported frequency configuration, operational frequency of the transmission and/or reception, signal strength of transmission and/or reception, and signal characteristics of transmission and/or reception.

3. The radio arrangement according to claim 1 , wherein the radio arrangement is configured to signal, from the antenna arrangement, the indication to the radio apparatus.

4. The radio arrangement according to claim 1 , wherein the radio arrangement is further configured to select signal path configuration at the antenna arrangement by transmitting a control signal to the antenna arrangement from the radio apparatus.

5. The radio arrangement according to claim 1 , further comprising another antenna arrangement connected to the radio apparatus, and the radio arrangement being configured to select signal path configuration where transmissions are convoyed to the antenna arrangement connected to the radio apparatus and receptions are convoyed to the other antenna arrangement connected to the radio apparatus or vice versa.

6. A radio apparatus for enabling communication in a wireless communication network, the radio apparatus being configured to
obtain an indication over a separate notification connection, which indication is at least one of: a non connection; a known resistor value; a known voltage; and a ground connection, and is indicating configuration of antenna arrangement connected to the radio apparatus; and
select, for communication in the wireless communication network, a signal path configuration, at the radio apparatus and/or the antenna arrangement, of at least two signal path configurations for transmitting and/or receiving signals to and/or from a radio device in the wireless communication network, based on the obtained indication.

7. The radio apparatus according to claim 6 , further being configured to select signal path configuration by controlling signal path in the antenna arrangement.

8. The radio apparatus according to claim 7 , further being configured to control signal path configuration in the antenna arrangement by transmitting a control signal to the antenna arrangement.

9. The radio apparatus according to claim 6 , being configured to obtain the indication by receiving a signal from the antenna arrangement.

10. The radio apparatus according to claim 9 , wherein the signal indicates antenna polarization, antenna gain, signal paths dedicated to receiving and transmitting or a signal path combining the receiving and transmitting, and/or orientation of the antenna arrangement.

11. The radio apparatus according to claim 6 , further being configured to select a signal path configuration for transmissions and a different signal path configuration for receptions.

12. The radio apparatus according to claim 11 , being configured to be connected to another antenna arrangement, and the radio apparatus is configured to select signal path configuration where transmissions are convoyed to the antenna arrangement connected to the radio apparatus and receptions are convoyed to the other antenna arrangement connected to the radio apparatus or vice versa.

13. The radio apparatus according to claim 12 , wherein the antenna arrangement comprises an external antenna and the other antenna arrangement comprises one or more internal antennas.

14. The radio apparatus according to claim 6 , wherein the signal path configuration is altered in the radio apparatus based on one or more radio parameters, which is at least one of the following: supported frequency configuration; operational frequency of the transmission and/or reception; signal strength of transmission and/or reception; and signal characteristics of transmission and/or reception.

15. A method performed in a radio arrangement for enabling communication in a wireless communication network, wherein the radio arrangement comprises at least two signal paths for transmitting and/or receiving signals to and/or from a radio device in the wireless communication network, a radio apparatus and an antenna arrangement connected to the radio apparatus, the method comprising:
obtaining, at the radio apparatus, an indication over a separate notification connection, which indication is at least one of: a non connection; a known resistor value; a known voltage; and a ground connection, and is indicating a configuration of the antenna arrangement connected to the radio apparatus; and
selecting, for communication in the wireless communication network, a signal path configuration at the radio apparatus and/or the antenna arrangement of the at least two signal path configurations based on the obtained indication.

16. The method according to claim 15 , wherein the signal path configuration is altered in the radio apparatus and/or in the antenna arrangement based on one or more radio parameters, which is at least one of the following: supported frequency configuration; operational frequency of the transmission and/or reception; signal strength of transmission and/or reception; and signal characteristics of transmission and/or reception.

17. The method according to claim 15 , comprising
signalling, from the antenna arrangement, the indication to the radio apparatus.

18. The method according to claim 15 , wherein the selecting comprises selecting signal path configuration at the antenna arrangement by transmitting a control signal to the antenna arrangement from the radio apparatus.

19. The method according to claim 15 , wherein the radio arrangement comprises another antenna arrangement connected to the radio apparatus, and the selecting comprises selecting the signal path configuration where transmissions are convoyed to the antenna arrangement connected to the radio apparatus and receptions are convoyed to the other antenna arrangement connected to the radio apparatus or vice versa.

20. A method performed in a radio apparatus for enabling communication in a wireless communication network, the method comprising
obtaining an indication over a separate notification connection, which indication is at least one of: a non connection; a known resistor value; a known voltage; and a ground connection, and is indicating a configuration of an antenna arrangement connected to the radio apparatus; and
selecting, for communication in the wireless communication network, a signal path
