Method and apparatus for receiving control channel for multiple numerologies in a wireless communications system

Abstract

Techniques for receiving control channel for multiple numerologies are disclosed. The UE receives a control channel by using a first numerology and receives a first data channel information by using a second numerology. The UE also receives a second data channel information by using the first numerology. Also, different numerologies and bandwidth portions are used for communicating data channel information and HARQ feedback respectively

What is claimed is: 
     
         1 . A method, comprising:
 configuring, by a user equipment (UE), use of a first numerology for receiving a control channel, wherein the control channel is indicative of a second numerology, wherein the first numerology is determined based upon the second numerology;   receiving, by the UE, information regarding using the second numerology for receiving a first data channel, wherein the control channel associated with the first numerology schedules the first data channel associated with the second numerology; and   receiving, by the UE, the control channel by using the first numerology and receiving by the UE the first data channel by using the second numerology.   
     
     
         2 . The method of  claim 1 , wherein the first numerology is a predefined numerology. 
     
     
         3 . The method of  claim 1 , wherein the second data channel is a common data channel. 
     
     
         4 . The method of  claim 1 , wherein the first data channel is for unicast data. 
     
     
         5 . The method of  claim 1 , wherein the second data channel is a broadcast channel. 
     
     
         6 . The method of  claim 1 , wherein the second numerology is configured by a radio resource control (RRC) message. 
     
     
         7 . The method of  claim 1 , wherein the control channel and the first data channel are in a same cell. 
     
     
         8 . The method of  claim 1 , comprising receiving, by the UE, information regarding using a third numerology for receiving a third data channel, wherein the first numerology is determined based upon the second numerology and the third numerology. 
     
     
         9 . The method of  claim 1 , wherein the second numerology is different for different time intervals. 
     
     
         10 . A method, comprising:
 receiving, by a user equipment (UE), information regarding using a first numerology for receiving a first data channel;   configuring, by the UE, use of a second numerology for receiving a control channel, wherein the control channel is indicative of a third numerology, wherein the second numerology is determined based upon the first numerology and the third numerology;   receiving, by the UE, information regarding using the third numerology for transmitting a second data channel, wherein the control channel associated with the second numerology schedules the second data channel associated with the third numerology; and   receiving, by the UE, the control channel by using the second numerology and transmitting by the UE the second data channel by using the third numerology.   
     
     
         11 . The method of  claim 10 , wherein the third numerology is configured by a radio resource control (RRC) message. 
     
     
         12 . The method of  claim 10 , comprising receiving, by the UE, information regarding using a fourth numerology for receiving a third data channel. 
     
     
         13 . A method, comprising:
 configuring, in association with a user equipment (UE), use of a first numerology for receiving a control channel, wherein the control channel is indicative of a second numerology, wherein the first numerology is determined based upon the second numerology;   providing, to the UE, information regarding using the second numerology for receiving a first data channel, wherein the control channel associated with the first numerology schedules the first data channel associated with the second numerology; and   providing, to the UE, the control channel by using the first numerology and providing to the UE the first data channel by using the second numerology.   
     
     
         14 . The method of  claim 13 , wherein the first numerology is a predefined numerology. 
     
     
         15 . The method of  claim 13 , wherein the second data channel is a common data channel. 
     
     
         16 . The method of  claim 13 , wherein the first data channel is for unicast data. 
     
     
         17 . The method of  claim 13 , wherein the second data channel is a broadcast channel. 
     
     
         18 . The method of  claim 13 , wherein the second numerology is configured by a radio resource control (RRC) message. 
     
     
         19 . The method of  claim 13 , wherein the control channel and the first data channel are in a same cell. 
     
     
         20 . The method of  claim 13 , comprising providing, to the UE, information regarding using a third numerology for receiving a third data channel, wherein the first numerology is determined based upon the second numerology and the third numerology.
