Phy layer multiplexing of different types of traffic in 5g systems

Abstract

Systems, methods, and instrumentalities are disclosed for physical (PHY) layer multiplexing of different types of traffic in 5G systems. A device may receive a communication. The communication may include a first traffic type. The device may monitor the communication for an indication that the communication includes a second traffic type that is multiplexed with and/or punctures the first traffic type. An indicator received in the communication and detected by the monitoring may indicate where the second traffic type is located in the communication. The first traffic type and the second traffic type may be multiplexed at a resource element (RE) level. For example, a first traffic type may be punctured by a second traffic type at the RE level. The device may de code one or more of the first or second traffic types in the communication based on the indication.

1 . A wireless transmit/receive unit (WTRU) that comprises:
 a processor, configured to:   receive a communication from a network entity, wherein the communication includes a first traffic type;   monitor the communication for an indicator, wherein to monitor the communication for the indicator comprises being configured to monitor a control channel in the communication for the indicator;   determine that the indicator is included in the communication;   determine that the communication is punctured by a second traffic type based on the indicator and determine a symbol associated with the second traffic type in the communication based on the indicator; and   decode at least one of the first traffic type or the second traffic type based on the indicator.   
     
     
         2 . The WTRU of  claim 1 , wherein the second traffic type is a low-latency traffic type, and wherein the low-latency traffic type has a latency requirement that is shorter than the first traffic type. 
     
     
         3 . (canceled) 
     
     
         4 . The WTRU of  claim 1 , wherein the first traffic type is an enhanced Mobile BroadBand (eMBB) traffic type, and the second traffic type is an ultra-reliable and low-latency (URLLC) traffic type. 
     
     
         5 . (canceled) 
     
     
         6 . The WTRU of  claim 1 , wherein the communication comprises at least one of a timing block, a chunk, a subframe, a transmission time interval (TTI), a subcarrier, a time sample, a mini-slot, or a time symbol. 
     
     
         7 . The WTRU of  claim 1 , wherein the indicator is used to determine at least one of time or frequency information, wherein the time information indicates which orthogonal frequency-division multiplexing (OFDM) symbols are punctured to carry the second traffic type, and wherein the frequency information indicates which subcarriers are punctured to carry the second traffic type. 
     
     
         8 . The WTRU of  claim 1 , wherein the second traffic type is processed before the first traffic type. 
     
     
         9 . (canceled) 
     
     
         10 . The WTRU of  claim 1 , wherein the control channel is located at an end of the communication. 
     
     
         11 . A method comprising:
 receiving a communication from a network entity, wherein the communication includes a first traffic type;   monitoring the communication for an indicator, wherein the monitoring comprises monitoring a control channel in the communication for the indicator;   determining that the indicator is included in the communication;   determining that the communication is punctured by a second traffic type based on the indicator and determine a symbol associated with the second traffic type in the communication based on the indicator; and   decoding at least one of the first traffic type or the second traffic type based on the the indicator.   
     
     
         12 . (canceled) 
     
     
         13 . (canceled) 
     
     
         14 . The method of  claim 11 , wherein the first traffic type is an enhanced Mobile BroadBand (eMBB) traffic type, and the second traffic type is an ultra-reliable and low-latency (URLLC) traffic type. 
     
     
         15 . (canceled) 
     
     
         16 . The method of  claim 11 , wherein the communication comprises at least one of a timing block, a chunk, a subframe, a transmission time interval (TTI), a subcarrier, a time sample, a mini-slot, or a time symbol. 
     
     
         17 . The method of  claim 11 , wherein the indicator is used to determine at least one of time or frequency information, wherein the time information indicates which orthogonal frequency-division multiplexing (OFDM) symbols are punctured to carry the second traffic type, and wherein the frequency information indicates which subcarriers are punctured to carry the second traffic type. 
     
     
         18 . The method of  claim 11 , wherein the second traffic type is processed before the first traffic type. 
     
     
         19 . (canceled) 
     
     
         20 . The method of  claim 11 , wherein the control channel is located at an end of the communication.
