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 5):
The pilot allocation method according to  claim 3 , wherein the quantity of the OCCs is 4, the quantity of the to-be-allocated ports is 8, and the determining, by the base station, a pilot allocation result according to the quantity of the newly-added to-be-allocated ports, the quantity of the OCCs, and a quantity of the UEs comprises:\n allocating, by the base station, 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 allocating 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, determining, by the base station, 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, determining, by the base station, 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.
