Dynamic PUCCH allocation

A system for physical uplink control channel (PUCCH) allocation, the system comprising:

• a processor;
• and
• a non-transitory computer-readable medium storing instructions that are operative upon execution by the processor to:
• receive, at a base station (BS) on a network, a session request message from a user equipment (UE), the session request message requesting a network session;
• based on at least receiving the session request message from the UE, determine a channel quality of a channel between the UE and the BS;
• based on at least the determined channel quality between the UE and the BS, select a first PUCCH format;
• monitor for channel conditions indicating that a second PUCCH format would improve expected channel quality between the UE and the BS;
• compare the expected channel quality between the UE and the BS with a change threshold, wherein the change threshold measures a difference in i) the determined channel quality of the channel between the UE and the BS and ii) the expected channel quality of the second PUCCH format;
• and
• based on the expected channel quality between the UE and the BS meeting or exceeding the change threshold, transmit a message, from the BS, to the UE, instructing the UE to configure the PUCCH according to the second PUCCH format.

One or more computer storage devices having computer-executable instructions stored thereon, which, upon execution by a computer, cause the computer to perform operations comprising:

• receiving, at a core network, a session request message from a base station (BS) forwarded from a user equipment (UE), the session request message requesting a network session;
• based on at least receiving the session request message from the BS, determining, by the core network, a channel quality of a channel between the UE and the BS;
• based on at least the determined channel quality between the UE and the BS, selecting, by the core network, a first physical uplink control channel (PUCCH) format;
• monitoring, by the core network, for channel conditions indicating that a second PUCCH format would improve expected channel quality between the UE and the BS;
• comparing, by the core network, the expected channel quality between the UE and the BS with a change threshold, wherein the change threshold measures a difference in i) the determined channel quality of the channel between the UE and the BS and ii) the expected channel quality of the second PUCCH format;
• and
• based on the expected channel quality between the UE and the BS meeting or exceeding the change threshold, transmitting a message, from the core network to the BS, the message including instructions for the UE to configure a PUCCH according to the second PUCCH format.
