Abstract: Embodiments of an enhanced Node B (eNB) and method for precoding with reduced quantization error are generally described herein. In some embodiments, first and second precoding-matrix indicator (PMI) reports may be received on an uplink channel and a single subband precoder matrix may be interpolated from precoding matrices indicated by both the PMI reports. Symbols for multiple-input multiple output (MIMO) beamforming may be precoded using the interpolated precoder matrix computed for single subband for a multiple user (MU)-MIMO downlink orthogonal frequency division multiple access (OFDMA) transmission. In some embodiments, each of the first and second PMI reports includes a PMI associated with a same subband that jointly describes a recommended precoder.

Abstract: A PDSCH resource element mapping method is used for joint transmissions. The method solves a problem of colliding resource elements in joint transmissions, due to interference caused when PDSCH resource elements are transmitted in the resource block of one cell and cell-specific reference signals (CRSs) are transmitted in the same location of the resource block of an adjacent cell. The method is particularly beneficial for coordinated multipoint (CoMP) transmissions. The PDSCH resource element mapping method employs one of three schemes for transmitting the collided resource elements, with minimal interference. In the first scheme, one PDSCH symbol is transmitted over three consecutive CRS-collided PDSCH resource elements. In the second scheme, two PDSCH symbols are transmitted over three consecutive CRS-collided PDSCH resource elements. In a third scheme, CRS-collided resource elements are transmitted using a lower modulation order than is specified by the modulation and coding scheme.

Abstract: An apparatus of a station (STA) includes memory and processing circuitry coupled to the memory. The processing circuitry is configured to encode a capabilities element for transmission to an access point (AP). The capabilities element including a media access control (MAC) capabilities information field indicating a trigger frame MAC padding duration. The processing circuitry decodes an extremely high throughput (EHT) protocol data unit (PPDU) received in response to the capabilities element. The EHT PPDU includes an EHT trigger frame (EHT-TF) in a data portion of the EHT PPDU, a packet extension (PE) field, and a dummy orthogonal frequency division multiplexing (OFDM) symbol extending the PE field. The processing circuitry performs physical layer (PHY) and MAC processing of the EHT PPDU based on a duration of the dummy OFDM symbol.

Abstract: An extremely high throughput (EHT) station (STA) configured for trigger based (TB) transmission may decode an trigger frame (TF) received from an access point (AP). The TF may include an assignment of resources comprising one or more 20 MHz channels. The EHT STA may determine which of the one or more assigned channels are available for transmission and which of the allocated channels are unavailable when the EHT STA is assigned more than one 20 MHz channel. The EHT STA may encode a EHT TB PPDU in response to the trigger frame. The EHT TB PPDU may be encoded to include an EHT preamble followed by a data field. The EHT preamble may be encoded to indicate channel availability. The EHT STA may generate signalling to cause the EHT STA to transmit the encoded EHT TB PPDU only on the assigned channels that have been determined to be available.
