Channel Symmetry for Communication System
A wireless device sends, to a network function, a message comprising a parameter indicating a request for symmetric communication channels for an application of the wireless device. The wireless device receives an acceptance of the request for the symmetric communication channels.
1 . A method comprising:
sending, by a wireless device to a network function, a message comprising a parameter indicating a request for symmetric communication channels for an application of the wireless device, wherein the symmetric communication channels comprise an uplink communication channel and a downlink communication channel having equal end-to-end latencies; and
receiving, by the wireless device, an acceptance of the request for the symmetric communication channels.
2 . The method of claim 1 , wherein the network function comprises a base station.
3 . The method of claim 2 , wherein the message comprises a radio resource control (RRC) request message.
4 . The method of claim 2 , wherein the acceptance of the request for the symmetric communication channels is received by the wireless device in a radio resource control (RRC) response message.
5 . The method of claim 4 , wherein the RRC response message comprises radio bearer configuration information for the symmetric communication channels.
6 . The method of claim 2 , further comprising sending, by the wireless device to the base station, a second message comprise an identity of the wireless device, wherein the identity of the wireless device indicates the request for the symmetric communication channels for the application of the wireless device.
7 . The method of claim 2 , further comprising receiving, by the wireless device from the base station, a physical layer message via a physical downlink control channel (PDCCH), the physical layer message comprising a downlink control information (DCI) indicating time and/or frequency resources for the symmetric communication channels.
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:
send, to a network function, a message comprising a parameter indicating a request for symmetric communication channels for an application of the wireless device, wherein the symmetric communication channels comprise an uplink communication channel and a downlink communication channel having equal end-to-end latencies; and
receive an acceptance of the request for the symmetric communication channels.
9 . The wireless device of claim 8 , wherein the network function comprises a base station.
10 . The wireless device of claim 9 , wherein the message comprises a radio resource control (RRC) request message.
11 . The wireless device of claim 9 , wherein the acceptance of the request for the symmetric communication channels is received by the wireless device in a radio resource control (RRC) response message.
12 . The wireless device of claim 11 , wherein the RRC response message comprises radio bearer configuration information for the symmetric communication channels.
13 . The wireless device of claim 9 , further comprising sending, by the wireless device to the base station, a second message comprise an identity of the wireless device, wherein the identity of the wireless device indicates the request for the symmetric communication channels for the application of the wireless device.
14 . The wireless device of claim 9 , further comprising receiving, by the wireless device from the base station, a physical layer message via a physical downlink control channel (PDCCH), the physical layer message comprising a downlink control information (DCI) indicating time and/or frequency resources for the symmetric communication channels.
15 . A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause a wireless device to:
send, to a network function, a message comprising a parameter indicating a request for symmetric communication channels for an application of the wireless device, wherein the symmetric communication channels comprise an uplink communication channel and a downlink communication channel having equal end-to-end latencies; and
receive an acceptance of the request for the symmetric communication channels.
16 . The non-transitory computer-readable medium of claim 15 , wherein the network function comprises a base station.
17 . The non-transitory computer-readable medium of claim 16 , wherein the message comprises a radio resource control (RRC) request message.
18 . The non-transitory computer-readable medium of claim 16 , wherein the acceptance of the request for the symmetric communication channels is received by the wireless device in a radio resource control (RRC) response message.
19 . The non-transitory computer-readable medium of claim 18 , wherein the RRC response message comprises radio bearer configuration information for the symmetric communication channels.
20 . The non-transitory computer-readable medium of claim 16 , further comprising sending, by the wireless device to the base station, a second message comprise an identity of the wireless device, wherein the identity of the wireless device indicates the request for the symmetric communication channels for the application of the wireless device.
