Random Access Information Based on Network Slices
A wireless device receives, from a first base station, configuration parameters of a cell, wherein the configuration parameters comprise first random access, RA, parameters, for at least one first network slice, indicating RA resources. The wireless device transmits one or more RA preambles for a RA procedure using the RA resources of the cell. The wireless device transmits to a second base station, a RA report of the RA procedure, wherein the RA report comprises at least one first identifier of the at least one first network slice.

transmitting, by the wireless device to a second base station, a RA report of the RA procedure, wherein the RA report comprises at least one first identifier of the at least one first network slice.
2 . The method of claim 1 , wherein the configuration parameters comprise second RA parameters for one or more services other than the at least one first network slice.
3 . The method of claim 2 , wherein the transmitting one or more RA preambles is for accessing the cell and using the at least one first network slice.

at least one second cell of the second base station.
5 . The method of claim 1 , wherein the RA report comprises the first RA parameters for the at least one first network slice.
6 . The method of claim 1 , wherein the receiving the configuration parameters of the cell comprises at least one of:
receiving, via the cell, at least one system information block comprising the configuration parameters of the cell; or
receiving a radio resource control (RRC) message comprising the configuration parameters of the cell, the RRC message comprising at least one of:
a RRC release message indicating that the wireless device transitions to an RRC inactive state or an RRC idle state; or
a RRC reconfiguration message.
7 . The method of claim 1 , further comprising determining, by the wireless device, at least one of:
a failure of the RA procedure via the cell; or
a success of the RA procedure via the cell.
8 . A wireless device comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive, from a first base station, configuration parameters of a cell, wherein the configuration parameters comprise first random access, RA, parameters, for at least one first network slice, indicating RA resources;
transmit, one or more RA preambles for a RA procedure using the RA resources of the cell; and
transmit, to a second base station, a RA report of the RA procedure, wherein the RA report comprises at least one first identifier of the at least one first network slice.
9 . The wireless device of claim 8 , wherein the configuration parameters comprise second RA parameters for one or more services other than the at least one first network slice.
10 . The wireless device of claim 9 , wherein the transmitting one or more RA preambles is for accessing the cell and using the at least one first network slice.
11 . The wireless device of claim 8 , wherein the transmitting the RA report comprises transmitting the RA report via one or more cells comprising at least one of:
the cell via which the wireless device transmitted the one or more preambles for the RA procedure; or
at least one second cell of the second base station.
12 . The wireless device of claim 8 , wherein the RA report comprises the first RA parameters for the at least one first network slice.
13 . The wireless device of claim 8 , wherein the receiving the configuration parameters of the cell comprises at least one of:
receiving, via the cell, at least one system information block comprising the configuration parameters of the cell; or
receiving a radio resource control (RRC) message comprising the configuration parameters of the cell, the RRC message comprising at least one of:
a RRC release message indicating that the wireless device transitions to an RRC inactive state or an RRC idle state; or
a RRC reconfiguration message.
14 . The wireless device of claim 8 , wherein the instructions further cause the wireless device to determine at least one of:
a failure of the RA procedure via the cell; or
a success of the RA procedure via the cell.
15 . A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause a wireless device to:
receive, from a first base station, configuration parameters of a cell, wherein the configuration parameters comprise first random access, RA, parameters, for at least one first network slice, indicating RA resources;
transmit, one or more RA preambles for a RA procedure using the RA resources of the cell; and
transmit, to a second base station, a RA report of the RA procedure, wherein the RA report comprises at least one first identifier of the at least one first network slice.
16 . The non-transitory computer-readable medium of claim 15 , wherein the configuration parameters comprise second RA parameters for one or more services other than the at least one first network slice.
17 . The non-transitory computer-readable medium of claim 16 , wherein the transmitting one or more RA preambles is for accessing the cell and using the at least one first network slice.
18 . The non-transitory computer-readable medium of claim 15 , wherein the transmitting the RA report comprises transmitting the RA report via one or more cells comprising at least one of:
the cell via which the wireless device transmitted the one or more preambles for the RA procedure; or
at least one second cell of the second base station.
19 . The non-transitory computer-readable medium of claim 15 , wherein the RA report comprises the first RA parameters for the at least one first network slice.
