Abstract
A method of a user equipment (UE) for power saving is provided. The method comprises receiving, from a serving cell, a set of configurations, receiving a power saving signal (PoSS) from a first downlink channel based on the received set of configurations, acquiring a first part of information for power saving from the PoSS, receiving, based on the received set of configurations, a second downlink channel that is a control channel, and acquiring a second part of information for the power saving from the received second downlink channel.
Claims20
A user equipment (UE) comprising:
- a receiver configured to:
- receive a configuration for a slot offset;
- receive configuration for a search space set;
- and
- receive a physical downlink control channel (PDCCH), according to the search space set in a common search space (CSS), in a slot that is before a slot corresponding to a start of a discontinuous reception (DRX) cycle by a number of slots equal to the slot offset;
- a decoder configured to decode a downlink control information (DCI) format in the PDCCH, wherein the DCI format includes a field indicating either reception or no reception of PDCCHs in a number of next DRX cycles;
- and
- a processor operably connected to the receiver, the processor configured to instruct the receiver, when the decoder correctly decodes the DCI format, to either receive or skip reception of the PDCCHs in the number of next DRX cycles based on the indication by the field in the DCI format.
A base station comprising:
- a transmitter configured to:
- transmit a configuration for a slot offset
- transmit of configuration for a search space set;
- and
- transmit a physical downlink control channel (PDCCH), according to the search space set in a common search space (CSS), in a slot that is before a slot corresponding to a start of a discontinuous reception (DRX) cycle by a number of slots equal to the slot offset;
- an encoder configured to encode a downlink control information (DCI) format in the PDCCH, wherein the DCI format includes a field indicating either transmission or no transmission of PDCCHs in a number of next DRX cycles;
- and
- a processor configured to instruct the transmitter to either transmit or to skip transmission of the PDCCHs in the number of next DRX cycles based on the indication by the field in the DCI format.
A method for physical downlink control channels (PDCCHs), the method comprising:
- receiving a configuration for a slot offset
- receiving configuration for a search space set;
- receiving a PDCCH, according to the search space set in a common search space (CSS), in a slot that is before a slot corresponding to a start of a discontinuous reception (DRX) cycle by a number of slots equal to the slot offset;
- decoding a downlink control information (DCI) format in the PDCCH, wherein the DCI format includes a field indicating either reception or no reception of PDCCHs in a number of next DRX cycles;
- and
- receiving the PDCCHs in the number of next DRX cycles or skipping reception of the PDCCHs in the number of next DRX cycles, when the decoder correctly decodes the DCI format, based on the indication by the field in the DCI format.
