The disclosure provides an apparatus for a user equipment (UE), comprising circuitry configured to: determine one or more numerologies defined for at least one of different codewords, different layers, and different links for a non-coherent joint transmission (NCJT) to the UE, the NCJT comprising a first transmission from a first access node and a second transmission from a second access node; and process the NCJT according to the determined one or more numerologies. Also provided is a configuration of one or more transmission schemes for at least one of different codewords, different layers, and different links for a NCJT to the UE. Some embodiments allow for uplink NCJT with one or more numerologies defined for at least one of different codewords, different layers, and different links.

Systems and methods of using blockwised DMRSs are generally described. A UE uses wideband or blockwised DMRSs as indicated by higher layer signaling or a DMRS scheme indicator of DCI. When transmitting blockwised DMRSs, the blockwised DMRSs have, for different resource blocks or DMRSs, DMRS cyclic shift hopping, different DMRS sequences, different phase rotation, and/or different scrambling sequences. The manner in which the blockwised DMRSs differ depend on the sequences or hopping are cell-specific or UE-specific, as well as whether the multiple symbols in a subframe are allocated to the UE to transmit the DMRSs.

Systems and methods of compensating for interference in a 5G system are generally described. An Interference Measurement Resource (IMR) is present in multiple resource elements of a subframe or a combination of a ZP and NZP Tracking Reference Signal (PT-RS) are used. An IMR covariance matrix is applied to compensate for the interference. The number of IMR subcarriers and symbols between adjacent IMRs is dependent on the numerologies and synchronization within the UE network. When the IMR is in multiple subcarriers in the first symbol of the second slot, and the matrix is determined using the IMR rather than a DMRS. The DCI comprises a flag that denotes whether IMR is enabled for a current PDCH, and indicates the manner to use the IMR. The subcarrier index for the NZP PT-RS overlaps the subcarrier index for the ZP PT-RS of another UE or gNB.

Described herein are base stations that may comprise a control module to segment a TB into one or more STBs, at least in part based on an ACK/NACK parameter, wherein a STB of the STBs may comprise one or more code blocks of the TB, and, to attach one or more first-level CRC bits to each of the STBs, and a transceiver to transmit the TB with the first-level CRC bits to a UE. Base stations may also comprise a transceiver to transmit a plurality of first code blocks and a first indicator to a UE, wherein the first indicator is further to indicate whether the first code blocks are new transmission blocks or not, and receive, from the UE, one or more ACK/NACK bits, and a control module to generate a second indicator to indicate whether the ACK/NACK bits have been correctly received by the base station or not.

Devices and methods of reducing overall Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) of user equipment (UE) using a large amount of carrier aggregation are generally described. The UE may receive a subframe from an enhanced NodeB (eNB). The subframe may contain a physical downlink control channel (PDCCH) formed in accordance with a Downlink Control information (DCI) format. The DCI format may comprise a Downlink Assignment Index (DAI) for Time Division Duplexed (TDD) and Frequency Division Duplexed (FDD) operation. The UE may determine, dependent on the DAI, a number and ordering of Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) bits to be transmitted on a Physical Uplink Shared Channel (PUSCH) and subsequently transmit the HARQ-ACK bits.
