    Abstract: A base station includes a controller configured to configure an MRS resource set comprising a group of MRS resources, each MRS resource comprising a set of MRS antenna ports. If at least two MRS antenna ports belong to a same MRS resource, then the at least two MRS antenna ports are quasi co-located with respect to a first set of QCL parameters, else if the at least two MRS antenna ports belong to a same MRS resource set, then the at least two MRS antenna ports are quasi co-located with respect to a second set of QCL parameters, and else the at least two MRS antenna ports are not quasi co-located with respect to either the first set or the second set of QCL parameters. The MRS is a CSI-RS for estimating a CSI and at least one of the first set and the second set of QCL parameters.

    Abstract: A user equipment (UE) performs a method for supporting discontinuous receive (DRX) in a wireless network. The method includes waking up at a wake up time associated with a beginning of a DRX cycle, the DRX cycle comprising a plurality of subframes. The method also includes determining whether to perform receive beam training before a beginning of a time period for downlink communication. The method further includes receiving data during the time period for downlink communication.

    Abstract: A resource allocation message includes a resource allocation field. The resource allocation field includes a first field that includes either a first sub-field or a first sub-field and a second sub-field with the first sub-field configured to hold a first value that indicates two or more logical indices and the second sub-field configured to hold a third value. Each of the logical indices is associated with a sub-band pair of resource units. The sub-band pair of resource units includes either a first sub-band resource unit or a first sub-band resource unit and a second sub-band resource unit. The resource allocation field also includes a second field configured to hold a second value that indicates, either alone or in combination with the third value, a first sub-band resource unit or a second sub-band resource unit for each of the sub-band pair of resource units indicated by the first field.

    Abstract: A user equipment, apparatus, and method are provided for wireless communication using an IG-OFDM structure. An apparatus is configured to transmit a known reference signal. The apparatus is configured to receive, in response to the reference signal and from at least one user equipment (UE), capability information that includes at least one of the sub-band bandwidth or number of independently decodable sub-bands that can be dynamically turned on or off by the at least one UE. The apparatus is configured to define an interleaved guard OFDM (IG-OFDM) structure according to the received capability information, the IG-OFDM structure including guard tones distributed within an OFDM symbol where there is no signal transmission on these guard tones. The apparatus is configured to communicate with the at least one UE using a transmitted waveform that is shaped according to the IG-OFDM structure.
