Abstract

This disclosure relates to implementations to support non-UE-specific (i.e. common) and UE-specific search spaces (SS) for M-PDCCH. One implementation relates to a UE comprising RF circuitry to receive, from an eNB, configuration information of one or a plurality of common Search Spaces (CSSs) for M-PDCCH; and baseband circuitry to monitor the one or more configured CSS for M-PDCCH transmissions; wherein the RF circuitry and/or baseband circuitry is adapted to support a reduced bandwidth (BW). Another implementation relates to an eNB comprising RF circuitry to transmit configuration information of a plurality of CSSs for M-PDCCH to one or more UEs supporting a reduced BW, wherein the plurality of CSSs for M-PDCCH are differentiated by “based on functionality”-differentiation that includes the type of use case and/or an EC level of the UE.

Claims20

Dependent claims

One or more baseband processors associated with a user equipment (UE) with reduced bandwidth (BW) support at both Radio Frequency (RF) and baseband, the baseband processor configured to perform operations comprising:

decoding configuration information, received from a base station, of one or more Common Search Spaces (CSSs) for M-PDCCH (Physical Downlink Control CHannel for MTC), the configuration information specifying a physical resource block (PRB) set for MDPCCH and a starting subframe of the M-PDCCH, the starting subframe being a function of a system frame number (SFN) or a function of an extended SFN, wherein the PRB set specifies a number of PRB pairs in the PRB set, and wherein a type of a scrambling of the configuration information is based on a type of a CSS of the one or more CSSs of the configuration information;
wherein the one or more CSSs are differentiated based on one or more enhanced coverage (EC) levels that are available to the one or more baseband processors, each CSS of the one or more CSSs configured for paging to a particular EC level of the one or more EC levels, the CSS defining, for the particular EC level, for one or more repetition levels;
determining an EC level;
and
based on the EC level, monitoring for M-PDCCH transmissions according to the CSS associated with the determined EC level.
