Abstract:
A downlink information processing method, user equipment, a base station, and a communications system are disclosed. In one aspect, a method performed by a terminal device such as user equipment (UE) includes: determining that a cell-specific frequency shift of downlink information is equal to a cell-specific frequency shift of a cell-specific reference signal (CRS), determining a resource element location according to the cell-specific frequency shift of the downlink information, where a duration of a transmission time interval (TTI) to which the resource element location belongs is less than or equal to a time length of one timeslot, receiving the downlink information at the resource element location, and demodulating downlink data according to the downlink information.

Claim (Index 18):
The base station according to  claim 17 , wherein the programming instructions instruct the at least one processor to determine a frequency domain index of the resource element location according to the cell-specific frequency shift of the downlink information by:\n determining the frequency domain index k of the resource element location according to a formula k=6m\u2032+N sc RB n PRB +(k\u2032+v shift2 )mod 6; l\u2260l\u2033, wherein m\u2032=0 or 1, k\u2032=0 or 3, l \u2033 = { 0 \ue89e \ue89e or \ue89e \ue89e N symb DL - 3 ; \ue89e if \ue89e \ue89e n s \ue89e \ue89e mod \ue89e \ue89e 2 = 1 \ue89e \ue89e and \ue89e \ue89e n = 1 \ue89e \ue89e or \ue89e \ue89e 2 0 , 1 , or \ue89e \ue89e N symb DL - 3 ; \ue89e if \ue89e \ue89e n s \ue89e \ue89e mod \ue89e \ue89e 2 = 1 \ue89e \ue89e and \ue89e \ue89e n = 4 \ue89e ( 0 \ue89e \ue89e to \ue89e \ue89e CFI - 1 ) \ue89e \ue89e or \ue89e \ue89e N symb DL - 3 ; \ue89e if \ue89e \ue89e n s \ue89e \ue89e mod \ue89e \ue89e 2 = 0 \ue89e \ue89e and \ue89e \ue89e n = 1 \ue89e \ue89e or \ue89e \ue89e 2 ( 0 \ue89e \ue89e to \ue89e \ue89e max \ue8a0 ( CFI - 1 , 1 ) ) \ue89e \ue89e or \ue89e \ue89e N symb DL - 3 ; if \ue89e \ue89e n s \ue89e \ue89e mod \ue89e \ue89e 2 = 0 \ue89e \ue89e and \ue89e \ue89e n = 4 \ue89e , N sc RB  represents a frequency domain resource block size, n PRB  represents a physical resource block number and is a positive integer, v shift2  represents the cell-specific frequency shift of the downlink information, n represents a quantity of antenna ports configured for CRSs sent by the base station, N symb DL  represents a quantity of orthogonal frequency division multiplexing (OFDM) symbols or single-carrier frequency division multiple access (SC-FDMA) symbols in one downlink timeslot, a CFI comprises control format indicator information carried on a physical control format indicator channel (PCFICH) sent by the base station, n s  represents an index of a timeslot in which the TTI is located, and l represents the time domain index of the resource element location.
