Description

Upward method and the field of wood

This relates to high- and long-term (TE, o g e Evo o Adva ced) wood, especially in the TEA system (R, Reay ode) or user terminal (E, se Eq p e) uplink method and system. Background

The communication systems of TEA and T dva ced, e a o a ob e Teeco ca o Adva ce are

(OF, OThogo a Feq e cy vso pex g) Mu Li. The long-term (TE, oge Evo o) system's downlink scheme is based on the OF wood force, in front of the OF (CP, Cyc c pe) to reduce the same, and support the downlink, that is, standing in the 1 meson can be the same 2 (T , TTa spo oc ). However, in the TE system, the uplink scheme uses the FAN (Feq e cy vso pex gAcces) wood force, which can only support the uplink sheep, that is, E can be the same in the meson.

The downlink control information (C, ow Co ooao ) in the TE is in the upper and lower directions of E, and the information of the S (Syse oao) / ( ag ) / RA (Ra do access) phase. In different modes, the TE system has several different downlink control information formats (C oa ). In addition to the most basic information, the God format is better than the solution (CS, od aoa dCod gSche e). , Reso ceAssg e ), except for the unique information of the god format, than, C a / A / / C / It is indicated that the degree of downhill sheep C a 2/2A is indicated by the degree of decline, and C a is expressed by the upward direction. Among them, the rest of the TE system used for uplink C a includes
