Abstract
A method for conserving the power supply of an Orthogonal Frequency Division Multiplexing (OFDM) communications device is described. The location of control information within one or two of a plurality of symbols is obtained. A sleep mode is entered into. The one or two symbols that include the control information are monitored. A return to the sleep mode is executed.
Claims22
A method for conserving the power supply of an Orthogonal Frequency Division Multiplexing (OFDM) communications device, comprising:
- obtaining a location of control information within one or two of a plurality of symbols, wherein the plurality of symbols comprises Layer (L1) downlink (DL) control symbols;
- entering into a sleep mode;
- monitoring the one or two symbols that include the control information, and not monitoring at least one symbol of the plurality of symbols;
- returning to the sleep mode;
- and
- wherein the OFDM communications device comprises a user equipment (UE).
A communications device in an Orthogonal Frequency Division Multiplexing (OFDM) system, wherein the communications device is configured to conserve its power supply, the communications device comprising:
- a processor;
- memory in electronic communication with the processor;
- instructions stored in the memory, the instructions being executable to:
- obtain a location of control information within one or two of a plurality of symbols, wherein the plurality of symbols comprises Layer (L1) downlink (DL) control symbols;
- enter into a sleep mode;
- monitor the one or two symbols that include the control information, and not monitor at least one symbol of the plurality of symbols;
- return to the sleep mode;
- and
- wherein the OFDM communications device comprises a user equipment (UE).
A base station that is configured to inform a communications device of a location of control information, the base station comprising:
- a processor;
- memory in electronic communication with the processor;
- instructions stored in the memory, the instructions being executable to:
- provide n Orthogonal Frequency Division Multiplexing (OFDM) symbols to send a Control Channel Element (CCE) per subframe, wherein n is a natural number;
- insert the CCE information for the said communications device into one or two of the OFDM symbols;
- and
- inform the said communications device which OFDM symbols include the CCE information.
A non-transitory computer-readable medium comprising executable instructions for:
- obtaining a location of control information within one or two of a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols, wherein the plurality of symbols comprises Layer 1 (L1) downlink (DL) control symbols;
- entering into a sleep mode by an Orthogonal Frequency Division Multiplexing (OFDM) communications device;
- monitoring the one or two symbols that include the control information, and not monitoring at least one symbol of the plurality of symbols;
- returning to the sleep mode;
- and
- wherein the OFDM communications device comprises a user equipment (UE).
