Facilitating uplink control channel decoding for advanced networks

Abstract

Facilitating uplink control channel decoding for advanced networks (e.g., 4G, 5G, and beyond) is provided herein. Operations of a system can comprise determining a channel estimate for an uplink control transmission received from a user equipment device via an uplink control channel, wherein the determining is based on a reference signal received from the user equipment device. The operations also can comprise determining a status of an acknowledgement that a data transmission was received by the user equipment device based on the channel estimate and a maximum likelihood estimation function.

What is claimed is: 
     
         1 . A method, comprising:
 determining, by network equipment comprising a processor, a status of an acknowledgement and a reference signal received from a user equipment, wherein the status is one of a hybrid automatic repeat request acknowledgement or a hybrid automatic repeat request non-acknowledgement, and wherein a first resource block comprising the reference signal is within a predetermined distance from a second resource block associated with a symbol of an uplink control transmission; and   interpolating, by the network equipment, a channel estimate for the uplink control transmission to the second resource block associated with the symbol.   
     
     
         2 . The method of  claim 1 , further comprising:
 prior to the determining, configuring, by the network equipment, the user equipment with information indicative of a position of the reference signal that is within a defined proximity to symbols of an uplink control channel format 0.   
     
     
         3 . The method of  claim 1 , wherein the determining comprises determining the status based on the channel estimate. 
     
     
         4 . The method of  claim 1 , wherein the determining comprises determining the status based on a maximum likelihood estimation function. 
     
     
         5 . The method of  claim 4 , wherein the maximum likelihood estimation function facilitates a selection of the hybrid automatic repeat request acknowledgement or the hybrid automatic repeat request non-acknowledgement. 
     
     
         6 . The method of  claim 1 , wherein the reference signal is associated with an estimation of channel state information associated with a data transmission to the user equipment. 
     
     
         7 . The method of  claim 1 , wherein the reference signal is associated with data demodulation. 
     
     
         8 . The method of  claim 1 , wherein the uplink control transmission conforms to a physical uplink control channel transmission format. 
     
     
         9 . The method of  claim 8 , wherein the uplink control channel transmission format is based on a sequence selection and facilitates user equipment multiplexing in a physical resource block. 
     
     
         10 . The method of  claim 8 , wherein the uplink control transmission is via an uplink control channel configured to operate according to a fifth generation communication network protocol. 
     
     
         11 . A system, comprising:
 a processor; and   a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
 transmitting a hybrid automatic repeat request acknowledgement in response to a determination that a data transmission was received successfully, wherein the hybrid automatic repeat request acknowledgement is associated with a symbol in a first resource block of an uplink transmission; and 
 transmitting a reference signal in a second resource block of the uplink transmission, wherein the second resource block is within a defined distance from the first resource block, wherein the uplink transmission is a control channel format 0, and wherein a channel estimate determined from the reference signal is interpolated to the first resource block associated with the symbol. 
   
     
     
         12 . The system of  claim 11 , wherein the operations further comprise:
 prior to the transmitting of the hybrid automatic repeat request acknowledgement, determining an uplink channel format setting and a reference signal setting based on an indication received via a physical downlink shared channel.   
     
     
         13 . The system of  claim 12 , wherein the operations further comprise:
 applying the uplink control channel format setting and the reference signal setting to the uplink transmission.   
     
     
         14 . The system of  claim 11 , wherein the uplink transmission conforms to a physical uplink control channel transmission format that facilitates device multiplexing in a physical resource block and is based on sequence selection. 
     
     
         15 . The system of  claim 11 , wherein the hybrid automatic repeat request acknowledgement is an encoded sequence. 
     
     
         16 . The system of  claim 11 , wherein the reference signal is a sounding reference signal. 
     
     
         17 . The system of  claim 11 , wherein the reference signal is a demodulation reference signal. 
     
     
         18 . A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
 determining a status of a data transmission sent to a user equipment based on a hybrid automatic repeat request and a reference signal received from the user equipment, wherein a first resource block comprising the reference signal is within a defined distance from a second resource block associated with a symbol of an uplink control transmission; and   interpolating a channel estimate for the uplink control transmission to the second resource block associated with the symbol.   
     
     
         19 . The non-transitory machine-readable medium of  claim 18 , wherein the operations further comprise:
 prior to the determining, configuring the user equipment with information indicative of a position of the reference signal that is within a defined proximity to symbols of an uplink control channel format 0.   
     
     
         20 . The non-transitory machine-readable medium of  claim 18 , wherein the determining comprises determining the status based on a maximum likelihood estimation function, and wherein the maximum likelihood estimation function facilitates a selection of a hybrid automatic repeat request acknowledgement or a hybrid automatic repeat request non-acknowledgement.
