Abstract:
The present invention discloses a pilot allocation method and apparatus, and relates to the field of wireless communications technologies, so as to resolve a problem that relatively strong pilot interference is generated between users on which MUBF pairing is performed. In the embodiments of the present invention, a base station determines user equipments UEs requiring multi-user beam forming MUBF pairing and to-be-allocated ports, sets a quantity of orthogonal cover codes OCCs according to a quantity of the to-be-allocated ports, and determines a pilot allocation result according to the quantity of the to-be-allocated ports, the quantity of the OCCs, and a quantity of the UEs. The solutions provided in the embodiments of the present invention are applicable to pilot allocation.

Claim (Index 10):
The pilot allocation apparatus according to  claim 8 , wherein the quantity of the OCCs is 4, the quantity of the to-be-allocated ports is 8, and\n the determining unit is further configured to: allocate an RE resource at a first location to four to-be-allocated ports of the eight to-be-allocated ports according to the OCCs, and allocate an RE resource at a second location to other four to-be-allocated ports; when the quantity of the UEs is less than or equal to 8, determine that the pilot allocation result is that each UE is corresponding to one to-be-allocated port, and N SCID  values corresponding to each to-be-allocated port are all 1 or are all 0; and when the quantity of the UEs is greater than 8, and is less than or equal to 16, determine that the pilot allocation result is that each to-be-allocated port is corresponding to one or two UEs, wherein when each to-be-allocated port is corresponding to one UE, N SCID  values of each to-be-allocated port are all 1 or are all 0, and when each to-be-allocated port is corresponding to two UEs, N SCID  values of the same to-be-allocated port corresponding to the two UEs are respectively 0 and 1.
