Timing offset for control signaling

Abstract

There is disclosed a method of operating a wireless device in a radio access network, the wireless device being configured with a slot configuration according to which a slot has multiple subslots. The method includes transmitting acknowledgement information reporting on subject transmission in a subslot based on a received timing indication indicating a subslot for transmitting the acknowledgement information, the timing indication being indicative of a subslot of a set of available subslots. Related methods and devices are also disclosed.

         5 . The method according to  claim 1 , wherein the acknowledgement information is transmitted based on TDD operation. 
     
     
         6 . The method according to  claim 1 , wherein the set of available subslots consists of subslots in slots configured for uplink transmission. 
     
     
         7 . The method according to  claim 1 , wherein the set of available subslots consists of subslots for which a resource for transmitting uplink control information has been configured. 
     
     
         8 . The method according to  claim 1 , wherein the set of available subslots consists of subslots that are arranged periodically in time. 
     
     
         9 . The method according to  claim 1 , wherein the timing indication is included in a control information message, which may be devoid of a timing indication explicitly indicating a slot for transmission of the acknowledgement information. 
     
     
         10 . The method according to  claim 1 , wherein the timing indication has a size in bits dependent on the number of elements of the set of available subslots. 
     
     
         11 . The method according to  claim 1 , wherein the set of available subslots consists of subslots in a reporting time interval. 
     
     
         12 . A computer storage medium storing a computer program comprising instructions configured to cause processing circuitry to at least one of control and perform a method of operating a wireless device in a radio access network, the wireless device being configured with a slot configuration according to which a slot has multiple subslots, the method comprising:
