Using a cell as a pathloss or timing reference
A radio access network sends, to a mobile device, information indicating a cell on a first carrier of a first type and a cell on a second carrier of a second type, and sends, to the mobile device, configuration information regarding whether the mobile device is to connect with a cell on another carrier of a new carrier type. The radio access network sends, to the mobile device, information relating to a Discontinuous Reception (DRX) configuration that is specific to a type of carrier.
1. A method comprising:
sending, by a radio access network to a mobile device, information indicating a cell on a first carrier of a first type and a cell on a second carrier of a second type;
sending, by the radio access network to the mobile device, configuration information regarding whether the mobile device is to connect with a cell on another carrier of a new carrier type;
sending, by the radio access network to the mobile device, information relating to a Discontinuous Reception (DRX) configuration that is specific to a type of carrier, wherein the sending of the DRX configuration comprises:
sending information relating to a first DRX configuration for communications with the cell on the first carrier of the first type, and
sending information relating to a second DRX configuration for communications with the cell on the another carrier of the new carrier type.
2. The method of claim 1 , wherein the configuration information comprises information to a reference signal to be measured by the mobile device.
3. The method of claim 1 , wherein the configuration information specifies use of semi-persistent scheduling (SPS) in the cell on the another carrier of the new carrier type.
4. The method of claim 1 , wherein the first carrier of the first type and the second carrier of the second type are part of a carrier aggregation.
5. The method of claim 1 , wherein the information indicating the cell on the first carrier of the first type and the cell on the second carrier of the second type is sent in system information.
6. The method of claim 1 , wherein the information indicating the cell on the first carrier of the first type and the cell on the second carrier of the second type is sent in at least one Radio Resource Control (RRC) message.
7. The method of claim 1 , further comprising:
sending, by the radio access network to the mobile device, configuration information specifying use of semi-persistent scheduling (SPS) in a cell on a carrier of a third type.
8. The method of claim 1 , wherein the first DRX configuration is different from the second DRX configuration.
9. The method of claim 1 , wherein the new carrier type is different from the first type.
10. A mobile device comprising:
at least one processor configured to:
receive, from a radio access network, information indicating a cell on a first carrier of a first type and a cell on a second carrier of a second type;
receive, from the radio access network, configuration information regarding whether the mobile device is to connect with a cell on another carrier of a new carrier type;
receive, from the radio access network, information relating to a Discontinuous Reception (DRX) configuration that is specific to a type of carrier, wherein the information relating to the DRX configuration comprises:
information relating to a first DRX configuration for communications with the cell on the first carrier of the first type, and
information relating to a second DRX configuration for communications with the cell on the another carrier of the new carrier type.
11. The mobile device of claim 10 , wherein the at least one processor is configured to further:
receive information specifying use of semi-persistent scheduling (SPS) in the cell on the another carrier of the new carrier type.
12. The mobile device of claim 11 , wherein the at least one processor is configured to further:
use resources according to the received information specifying use of SPS.
13. The mobile device of claim 10 , wherein the information indicating the cell on the first carrier of the first type and the cell on the second carrier of the second type is in system information from the radio access network or in at least one Radio Resource Control (RRC) message from the radio access network.
14. The mobile device of claim 10 , wherein the configuration information comprises information to a reference signal to be measured by the mobile device.
15. The mobile device of claim 10 , wherein the first carrier of the first type and the second carrier of the second type are part of a carrier aggregation.
16. A network node for a radio access network, comprising:
at least one processor configured to:
send, from the network node to a mobile device, information indicating a cell on a first carrier of a first type and a cell on a second carrier of a second type;
send, from the network node to the mobile device, configuration information regarding whether the mobile device is to connect with a cell on another carrier of a new carrier type;
send, from the network node to the mobile device, information relating to a Discontinuous Reception (DRX) configuration that is specific to a type of carrier, wherein the information relating to the DRX configuration comprises:
information relating to a first DRX configuration for communications with the cell on the first carrier of the first type, and
information relating to a second DRX configuration for communications with the cell on the another carrier of the new carrier type.
17. The network node of claim 16 , wherein the configuration information comprises information relating to a reference signal to be measured by the mobile device.
18. The network node of claim 16 , wherein the configuration information specifies use of semi-persistent scheduling (SPS) in the cell on the first carrier of the first type.
19. The network node of claim 16 , wherein the first carrier of the first type and the second carrier of the second type are part of a carrier aggregation.
20. The network node of claim 16 , wherein the first DRX configuration is different from the second DRX configuration, and the new carrier type is different from the first type.
