  • Table-based resource mapping for downlink control channels in a wireless system base station
    Patent number: 8798010
    Abstract: A transmitter comprises resource mapping circuitry configured to map symbols from multiple control channels to transmission symbols in a base station of a wireless system. The resource mapping circuitry comprises a table-based mapper configured to receive the control channel symbols and to map those symbols to the transmission symbols utilizing at least a selected one of a plurality of tables providing respective distinct mappings between the control channel symbols and the transmission symbols. For example, each of the transmission symbols may comprise a plurality of resource groups and the tables may specify distinct mappings of the control channels symbols to resource groups for different sets of possible base station parameter values. In one embodiment, the control channels comprise a physical control format indicator channel (PCFICH), a physical downlink control channel (PDCCH), and a physical hybrid ARQ indicator channel (PHICH) of an LTE cellular system.
