This application provides a downlink information transmission method, apparatus, and a device. The method includes: encoding information into a plurality of transport blocks; determining a time-frequency resource used to send each transport block; sending downlink resource indication information to user equipment, where the downlink resource indication information indicates a time-frequency resource location occupied by an M.sup.th transport block; and sending corresponding transport blocks on the time-frequency resources.

Methods and systems are provided for a protected communications architecture in which a pool of limited availability channels are shared through the transmission of encoded symbols with time-varying path diversity by a pool of users. The communications architecture can be managed by a network controller that stores availability data describing the availability of multiple-access satellite communications channels. The network controller allocates a first user to a first time-varying subset of the plurality of multiple-access satellite or terrestrial communications channels based on the availability data. The network controller updates the availability data based on the allocation of the first user. The network controller allocates a second user to a second time-varying subset of the plurality of multiple-access satellite or terrestrial communications channels based on the updated availability data. This process is repeated until all users are allocated bandwidth based on their priority, demand, and the overall bandwidth available within the pool.

A network device receives first data associated with a first transmission received at a second antenna from a first antenna and stores the first data as a first antenna profile associated with the second antenna. The network device uses the stored first antenna profile for determining at least one first transmission characteristic associated with a third antenna transmitting to the second antenna.

Disclosed is a transmission scheme for transmitting a first modulated signal and a second modulated signal over the same frequency at the same time. According to the transmission scheme, a precoding weight multiplying unit multiplies a baseband signal after a first mapping and a baseband signal after a second mapping by a precoding weight and outputs the first modulated signal and the second modulated signal. In the precoding weight multiplying unit, precoding weights are regularly hopped.
