Abstract
This disclosure relates to implementations to support UE-specific search space (UESS) for wide coverage enhancement (WCE). One implementation relates to an apparatus of a user equipment (UE) comprising: an interface configured to receive configuration information of a UE specific Search Space (UESS) and a common search space (CSS) for enhanced Physical Downlink Control Channel (ePDCCH) from a radio-frequency (RF) circuitry; and a processor configured to monitor the UESS and the CSS for ePDCCH transmission; wherein the interface and/or the processor is adaptable to support a wideband coverage enhancement (WCE).
Claims25
An apparatus of a user equipment (UE) comprising:
- an interface configured to receive configuration information of a UE specific Search Space (UESS) and a Common Search Space (CSS) for enhanced Physical Downlink Control Channel (ePDCCH) from a radio-frequency (RF) circuitry;
- and
- a processor configured to monitor the UESS and the CSS for ePDCCH transmission;
- wherein the interface and/or the processor is adaptable to support a wideband coverage enhancement (WCE), and the configuration information includes information for configuration of one or more of:
- candidate Search Space (SS),
- Resource Block (RB) for the UESS and the CSS for ePDCCH transmission,
- search space reduction, or
- transmission of Downlink Control Information (DCI).
An apparatus of a user equipment (UE) comprising:
- an interface configured to receive configuration information of a Search Space (SS) for Machine-type communications Physical Downlink Control Channel (MPDCCH) from a radio-frequency (RF) circuitry;
- and
- a processor configured to monitor the SS for an MPDCCH transmission;
- wherein the interface and/or the processor is adaptable to support a frequency hopping Internet of Things (IoT) system, and
- the MPDCCH transmission is restricted with starting N1 downlink subframes, N1 being configured by an evolved Node-B (eNB) through high layer signaling, and the starting N1 downlink subframes are less than the length of dwell time of a data channel.
An apparatus of a user equipment (UE) comprising:
- a radio-frequency (RF) interface configured to receive configuration information for Physical Downlink Control Channel (PDCCH) transmission with a reference signal on a contiguous downlink/uplink configuration, and
- a processor configured to monitor the PDCCH transmission;
- wherein the Downlink (DL) transmission is finished within one dwell time, and the PDCCH transmission comprises a System Information (SI) transmission including an essential System Information Block (SIB) and remaining SIB1.
