The apparatus includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to perform at least the following: receive from a user equipment correspondence information that relates channel states of a first set to channel states of a second set (302); receive from the user equipment an indication of at least one channel state of the first set which was measured on a downlink (304); use the received indication of at least one channel state of the first set and the received correspondence information to determine a channel state from the second set (306); and adapt a transmission on a downlink channel for the user equipment using the determined channel state (308).

摘要： A network signals an allocation (PDCCH) for a downlink shared channel (PDSCH); and also signals an indication (reference signal RS) whether a resource block (PRB) comprising the allocated downlink shared channel is used for a control channel transmission (E-PDCCH). Examples include the E-PDCCH being time or frequency multiplexed with the PDSCH; and the indication being a different RS sequence (at least one element being phase shifted) than an original RS sequence used if the PRB were not used for the E-PDCCH. The UE tests for the phase shift by blind decoding. If the phase shift is present the UE a) decodes a portion of the PRB for data if the network is using TDM for its E-PDCCH/PDSCH multiplexing, orb) decodes the full PRB only for the E-PDCCH if the network is using FDM for its E-PDCCH/PDSCH multiplexing.

摘要： A reference signal cyclic shift (CS) is quantized as a combination of a cell specific CS with an outcome of a pseudo-random hopping, and an indication of the cell specific CS is broadcast in the cell. In one embodiment the CS is quantized as a modulo operation on a sum of the cell specific CS, the outcome of the pseudo-random hopping, and a user specific CS, in which case an indication of the user specific CS is sent in an uplink resource allocation and a user sends its cyclically shifted reference signal in the uplink resource allocated by the uplink resource allocation. The CS may also be quantized according to length of the reference signal as cyclic_shift_symbol=(cyclic_shift_value*length of the reference signal)/12; where cyclic_shift_value is between zero and eleven and cyclic_shift_symbol is the amount of CS given in reference signal symbols.
