Abstract

Claims (42)

1. A method comprising:

transmitting, by a base station to a wireless device, system information indicating one or more first parameters of a random access process; and

receiving, in response to initiation of the random access process by the wireless device, a transport block comprising a radio resource control (RRC) setup request message, wherein:

the RRC setup request message is associated with an identity;

the identity indicates that the wireless device is a reduced capability wireless device; and

the reduced capability wireless device is associated with reduced capabilities compared to a non-reduced capability wireless device.

2. The method of claim 1 , wherein the reduced capabilities comprise one or more of:

a reduced bandwidth;

a reduced number of antennas;

a half-duplex operation;

a relaxed processing time; and

a relaxed processing capability.

3. The method of claim 1 , wherein the identity is based on a wireless device type.

4. The method of claim 1 , wherein the one or more first parameters are for reduced capability wireless devices.

5. The method of claim 1 , wherein the transmitting the one or more first parameters is based on a system information block message.

6. The method of claim 1 , wherein the system information comprise one or more second parameters that are for non-reduced capability wireless devices.

7. The method of claim 1 , wherein the RRC setup request message is associated with a common control channel (CCCH) logical channel.

8. The method of claim 1 , wherein the initiation of the random access process is for transitioning from an RRC idle state to an RRC connected state.

9. The method of claim 1 , wherein the receiving the transport block is via a random access message.

10. The method of claim 9 , wherein the random access message is Msg3.

11. A base station comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the base station to:

transmit, to a wireless device, system information indicating one or more first parameters of a random access process; and

receive, in response to initiation of the random access process by the wireless device, a transport block comprising a radio resource control (RRC) setup request message, wherein:

the RRC setup request message is associated with an identity;

the identity indicates that the wireless device is a reduced capability wireless device; and

the reduced capability wireless device is associated with reduced capabilities compared to a non-reduced capability wireless device.

12. The base station of claim 11 , wherein the reduced capabilities comprise one or more of:

a reduced bandwidth;

a reduced number of antennas;

a half-duplex operation;

a relaxed processing time; and

a relaxed processing capability.

13. The base station of claim 11 , wherein the identity is based on a wireless device type.

14. The base station of claim 11 , wherein the one or more first parameters are for reduced capability wireless devices.

15. The base station of claim 11 , wherein transmitting the one or more first parameters is based on a system information block message.

16. The base station of claim 11 , wherein the system information comprise one or more second parameters that are for non-reduced capability wireless devices.

17. The base station of claim 11 , wherein the RRC setup request message is associated with a common control channel (CCCH) logical channel.

18. The base station of claim 11 , wherein the initiation of the random access process is for transitioning from an RRC idle state to an RRC connected state.

19. The base station of claim 11 , wherein receiving the transport block is via a random access message.

20. The base station of claim 19 , wherein the random access message is Msg3.
