Abstract

A method for operating a user equipment (UE) configured for estimating channel quality includes receiving a downlink fractional control channel from a non-serving HS-DSCH cell, estimating a quality of the downlink fractional control channel over a specified time period, and deriving downlink synchronization primitives in accordance with the quality of the downlink fractional control channel. Further methods for deriving the transmit power of an uplink control channel from downlink fractional control channels transmitted by the serving and non-serving HS-DSCH cells are disclosed.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for operating a user equipment (UE) configured for estimating channel quality, the method comprising:
 receiving, by the UE, a downlink fractional control channel; and   reporting, by the UE, a signal that indicates downlink synchronization primitives derived in accordance with a quality of the downlink fractional control channel over a time period.   
     
     
         2 . The method of  claim 1 , wherein the signal that indicates the downlink synchronization primitives is a higher layer signal. 
     
     
         3 . The method of  claim 1 , the downlink fractional control channel is a fractional dedicated physical channel (F-DPCH NON-SERVING ) and an uplink physical control channel comprises a secondary dedicated physical control channel (DPCCH2). 
     
     
         4 . The method of  claim 1 , the downlink synchronization primitives include a CPHY-Sync-IND. 
     
     
         5 . The method of  claim 1 , the downlink synchronization primitives include a CPHY-Out-of-Sync-IND. 
     
     
         6 . The method of  claim 1 , wherein the downlink fractional control channel is received from one of a high-speed downlink shared channel (HS-DSCH) cell and an enhanced dedicated channel (E-DCH) cell when E-DCH decoupling is configured. 
     
     
         7 . The method of  claim 1 , wherein the downlink synchronization primitives are derived from a quality of transmit power control (TPC) fields in the downlink fractional control channel. 
     
     
         8 . A user equipment (UE) comprising:
 a processor; and   a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
 receive a downlink fractional control channel; and 
 report a signal that indicates downlink synchronization primitives derived in accordance with a quality of the downlink fractional control channel over a time period. 
   
     
     
         9 . The UE of  claim 8 , wherein the signal that indicates the downlink synchronization primitives is a higher layer signal. 
     
     
         10 . The UE of  claim 8 , the downlink fractional control channel is a fractional dedicated physical channel (F-DPCH NON-SERVING ) and an uplink physical control channel comprises a secondary dedicated physical control channel (DPCCH2). 
     
     
         11 . The UE of  claim 8 , the downlink synchronization primitives include a CPHY-Sync-IND. 
     
     
         12 . The UE of  claim 8 , the downlink synchronization primitives include a CPHY-Out-of-Sync-IND. 
     
     
         13 . The UE of  claim 8 , wherein the downlink fractional control channel is received from one of a high-speed downlink shared channel (HS-DSCH) cell and an enhanced dedicated channel (E-DCH) cell when E-DCH decoupling is configured. 
     
     
         14 . The UE of  claim 8 , wherein the downlink synchronization primitives are derived from a quality of transmit power control (TPC) fields in the downlink fractional control channel. 
     
     
         15 . A computer program product comprising a non-transitory computer readable storage medium storing programming, the programming including instructions to:
 receive, by a user equipment (UE), a downlink fractional control channel; and   report, by the UE, a signal that indicates downlink synchronization primitives derived in accordance with a quality of the downlink fractional control channel over a time period.   
     
     
         16 . The computer program product of  claim 15 , the downlink fractional control channel is a fractional dedicated physical channel (F-DPCH NON-SERVING ) and an uplink physical control channel comprises a secondary dedicated physical control channel (DPCCH2). 
     
     
         17 . The computer program product of  claim 15 , the downlink synchronization primitives include a CPHY-Sync-IND. 
     
     
         18 . The computer program product of  claim 15 , the downlink synchronization primitives include a CPHY-Out-of-Sync-IND. 
     
     
         19 . The computer program product of  claim 15 , wherein the downlink fractional control channel is received from one of a high-speed downlink shared channel (HS-DSCH) cell and an enhanced dedicated channel (E-DCH) cell when E-DCH decoupling is configured. 
     
     
         20 . The computer program product of  claim 15 , wherein the downlink synchronization primitives are derived from a quality of transmit power control (TPC) fields in the downlink fractional control channel.
