Abstract: Aspects of this disclosure relate to resource mapping schemes. One embodiments is an apparatus including one or more processors coupled to a memory interface, and configure to encode a two part CSI that includes information bits of a first UCI type and information bits of a second UCI type. The First UCI type is a HARQ-ACK and the second the second UCI type is a SR. The encoded information bits of the first UCI type and the second UCI type are mapped onto a first physical resource. The first physical resource and a second physical resource are multiplexed in a TDM manner and the first physical resource precedes the second physical resource in a time domain. Information bits of the first and second UCI types are jointly encoded to respectively generate encoded HARQ-ACK bits and encoded SR bits. The two part CSI is output in a PUCCH.

Abstract: User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for multi-transmission reception point (TRP) reception, the processing circuitry is to decode radio resource control (RRC) signaling. The RRC signaling includes configuration information configuring a plurality of transmission configuration indication (TCI) states. A media access control (MAC) control element (CE) is decoded, where the MAC CE indicates multiple active TCI states of the configured plurality of TCI states. Multiple received beams are determined using the multiple active TCI states. Downlink information is decoded, where the downlink information originates from multiple TRPs and is received via the determined multiple receive beams associated with the multiple active TCI states.

Abstract: A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode radio resource control (RRC) signaling to obtain a cyclic shift value in time domain. The cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs. A single carrier based waveform DM-RS sequence corresponding to the DM-RS AP is generated using a base sequence and the cyclic shift value. The single carrier based waveform DM-RS sequence is encoded with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency.

Abstract: A user equipment (UE) can include processing circuitry configured to decode control information of a physical down-in link control channel (PDCCH) received via a resource within a control resource set (CORESET) occupying a subset of a plurality of e OFDM symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCH. The DM-RS can be detected within the slot, the DM-RS starting at a symbol 01 location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data scheduled by the
PDCCH and received via the PDSCH can be decoded, where the decoding is based on the detected DM-RS.

Abstract: User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for channel state information (CSI) reporting in a 5G network, the processing circuitry is to decode a radio resource control (RRC) configuration message, the RRC configuration message including first configuration information to configure determination of channel quality information (CQI), a rank indicator (RI), and a precoding matrix indicator (PMI) for the CSI reporting. Second configuration information is decoded to configure codebook parameters for a high spatial resolution codebook associated with the PMI. A precoding matrix is determined based on the first configuration information, where a number of coefficients in at least one coefficient vector of the precoding matrix is configured using the second configuration information. CSI is encoded for transmission to a base station, the CSI including the RI and the PMI associated with the determined precoding matrix.

Abstract: A user equipment (UE) can include processing circuitry configured to decode downlink control information (DCI) from a base station, the DCI including a modulation coding scheme (MCS) index and physical uplink shared channel (PUSCH) allocation. A demodulation reference signal (DM-RS) is encoded for transmission to the base station within a plurality of DM-RS symbols based on the PUSCH allocation. A phase tracking reference signal (PT-RS) time domain density is determined based on the MCS index and a number count of the DM-RS symbols for the DM-RS transmission. The PT-RS is encoded for transmission using a plurality of PT-RS symbols based on the determined time domain density. The plurality of symbols includes one or both of front-loaded DM-RS symbols and additional DM-RS symbols.
