Abstract
For applying a random phase to blocks within a multicast transmission, methods, apparatus, and systems are disclosed. One apparatus includes a processor and a transceiver that communicates with at least one remote unit. The processor divides a downlink transmission into a plurality of phase blocks, each phase block including a plurality of resource blocks. The processor applies a random phase to signals corresponding to each of the plurality of phase blocks, forming a randomly-phased transmission. Moreover, the transceiver transmits the randomly-phased transmission to the at least one remote unit as multicast data.
Claims20
A method comprising:
- dividing, by a base unit, a downlink transmission for a selected user equipment into a plurality of phase blocks, each phase block comprising a plurality of resource blocks;
- applying a random phase to signals corresponding to each of the plurality of phase blocks to form a randomly-phased transmission to the selected user equipment, wherein the randomly-phased transmission include the plurality of phase blocks, each phase block having a different random phase applied;
- and
- transmitting the randomly-phased transmission as multicast data.
An apparatus comprising:
- a transceiver that communicates with at least one remote unit;
- and
- a processor that:
- divides a downlink transmission for a selected remote unit of the at least one remote unit into a plurality of phase blocks, each phase block comprising a plurality of resource blocks;
- and
- applies a different random phase to each of the plurality of phase blocks to form a randomly-phased transmission to the selected remote unit,
- wherein the transceiver transmits the randomly-phased transmission to the at least one remote unit as multicast data.
A method comprising:
- receiving, at a remote unit, a multicast transmission from a base unit;
- identifying, by the remote unit, a plurality of phase blocks in the multicast transmission, each phase block having a different random phase applied and comprising a plurality of resource blocks;
- performing channel estimation on the plurality of phase blocks;
- and
- decoding the multicast transmission using the channel estimations.
An apparatus comprising:
- a transceiver that communicates with a base unit in a mobile communication network;
- and
- a processor that:
- receives a multicast transmission from the base unit;
- identifies a plurality of phase blocks in the multicast transmission, each phase block having a different random phase applied and comprising a plurality of resource blocks;
- performs channel estimation on the plurality of phase blocks;
- and
- decodes the multicast transmission using the channel estimations.
