Abstract: This disclosure relates to techniques for performing wireless communications including signaling resource allocation for multiple transport blocks (TBs) on either PUSCH or PDSCH using a single control element, such as a DCI. In various scenarios, the multiple TBs may be scheduled either at contiguous or at non-contiguous dime-domain resources. Various mechanisms are disclosed for performing signaling the resource allocation for the multiple TBs without introducing excessive signaling overhead.

Abstract: Aspects herein relate to wireless devices, circuits, and methods for determining a PRACH resource mapping comprising a starting symbol position within a reference slot, wherein the starting symbol position is determined based, at least in part, on a subcarrier spacing configuration of PRACH resources of a wireless network that a wireless device is operating on; and using the radio to transmit a RACH preamble and an associated RA-RNTI via the determined PRACH resource mapping. Further aspects herein relate to devices, circuits, and methods for using a modified RA-RNTI for transmission or reception of data over a wireless network, wherein the wireless network has a subcarrier spacing configuration of PRACH resources, wherein a size of the subcarrier spacing configuration of the PRACH resources causes out-of-range RA-RNTI values to be calculated using a legacy RA-RNTI equation in an unmodified form, wherein the range of permissible RA-RNTI values is from 0 to 216−1.

Abstract: Systems and methods are provided for handling different timing advance (TA) adjustment delays corresponding to different transmission time intervals (TTIs) from different serving cells under carrier aggregation or dual connectivity. A user equipment (UE) selects and implements one TA adjustment delay even if two or more serving cells transmit with different TTIs. In one embodiment, the UE uses a predetermined TA adjustment delay for each of a plurality of TA commands received from serving cells with different TTI lengths. In another embodiment, the UE uses a TA adjustment delay that is a maximum value of the TA adjustment delays for the TTIs from the different serving cells.

Abstract: The implementations disclosed provide apparatus, systems, and methods for downlink control information (DCI) enhancement for a reduced-complexity new radio (NR) wireless device. The wireless device includes one or more processors configured to transmit a type of the wireless device to a base station communicatively coupled to the wireless device. A format of the DCI is received from the base station. The DCI includes multiple bit strings indicating a schedule of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH). The format specifies a respective number of bits for each bit string. The format is defined by the base station based on the type of the wireless device. The DCI is received from the base station using a physical downlink control channel (PDCCH). The multiple bit strings are extracted from the DCI based on the format of the DCI.

Abstract: Apparatus that sends uplink control information (UCI) from user equipment (UE) to a network node, generates elements of the UCI including at least one of hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback for one or more uplink (UL) resources, a scheduling request (SR), a channel state information (CSI) report and a beam related information report in response to a trigger set by the network node. The apparatus encodes the UCI elements for transmission via a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) of the one or more UL resources. The one or more UL resources may be UL slots or UL portions of downlink-uplink (DL-UL) slots received from a network node.

Abstract: Some embodiments of this disclosure include apparatuses and methods for physical downlink control channel design for a discrete Fourier Transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) waveform. The apparatuses and methods can include at least operating a base station (BS) to generate one or more physical downlink control channels (PDCCH) in a time division multiplexing (TDM) manner using a Discrete Fourier Transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) waveform, generate a demodulation reference signal (DMRS) which is multiplexed in the TDM manner with the one or more PDCCH, and transmit the one or more PDCCH and the DMRS to a user equipment (UE).

Abstract: Technology for a user equipment (UE) operable to encode a New Radio (NR) short duration physical uplink control channel (PUCCH) for transmission to a Next Generation NodeB (gNB) is disclosed. The UE can identify uplink control information (UCI) for the UE. The UE can multiplex, using frequency division multiplexing (FDM) at the UE, the UCI and a pseudo-random sequence associated with a demodulation reference signal (DMRS) onto a plurality of subcarriers in one or more physical resource blocks (PRBs) of one or more orthogonal frequency division multiplexing (OFDM) symbols. The UE can encode the UCI and the pseudo-random sequence associated with the DMRS multiplexed onto the plurality of subcarriers of the one or more OFDM symbols for transmission on the NR short duration PUCCH to the gNB.

Abstract: Techniques for contention window size (CWS) adaptation (CWSA) are discussed. One example apparatus can comprise a processor that can receive HARQ messages UEs in response to PDSCH transmissions in one or more reference subframes. The HARQ messages can comprise HARQ-ACK values that denote a HARQ-ACK state for a transport block associated with License Assisted Access (LAA) operation, wherein each of the HARQ-ACK states is one of a DTX state, an ACK state, a NACK state, or an “any” state. The processor can also; determine a metric value for each of the HARQ-ACK states; calculate a CWS adjustment metric based on the determined metric values; increase a CWS to a next higher allowed value when the CWS adjustment metric is greater than or equal to a threshold; and reset the CWS to a minimum allowed value when the CWS adjustment metric is less than the threshold.
