Abstract: Embodiments of dynamic multiplexing are described, including the transmission of preemption indication (PI) to indicate preemption of time-frequency resources. In some embodiments, a next Generation NodeB (gNB) is configured to transmit PIs in signaling to preempt an enhanced Mobile Broadband (eMBB) communications transmission with an ultra-reliable and low latency communications (URLCC) transmission. In some embodiments, a user equipment (UE) is configured to monitor a region of time-frequency resources, within a bandwidth part (BWP), for a PI. The PI indicates to the UE a portion of time-frequency resources that omit transmissions intended for the UE. In some embodiments, the gNB transmits the PI to the UE within preemption indication downlink control information (PI-DCI) in a physical downlink control channel (PDCCH) in a control resource set (CORESET). In some embodiments, the BWP is defined according to a frequency domain location, a bandwidth, and a subcarrier spacing for a given numerology.

Abstract: Technology for a UE is disclosed. The UE can identify that a resource for a PUCCH transmission with HARQ-ACK information and/or a resource for a PUCCH associated with a SR overlap in time with two resources for respective PUCCH transmissions with two CSI reports. The UE can select a resource for a PUCCH transmission with a CSI report having a higher priority from the two resources for respective PUCCH transmissions with the two CSI reports. The UE can multiplex the HARQ-ACK information and/or the SR in the selected resource for the PUCCH transmission with the CSI report having the higher priority. The UE can encode the multiplexed HARQ-ACK information and the SR and the CSI report for transmission on the selected resource for the PUCCH transmission to a NR base station. The UE can drop the CSI report and the PUCCH resource having a lower priority.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive radio resource control (RRC) signaling that configures reception of a plurality of physical downlink shared channels (PDSCHs) in a frame. The frame may comprise multiple slots, including one or more downlink slots and one or more uplink slots. The UE may determine a subset of the PDSCHs, such that for each of the PDSCHs of the subset, corresponding consecutive slots do not overlap the uplink slots. The UE may set a number of bits of a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook equal to a number of PDSCHs in the determined subset.

Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with an Evolved Node-B (eNB) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to allocate a first set of Resource Elements (REs) for a set of Uplink Control Information (UCI) types corresponding with a first set of frequency resources. The first circuitry may also be operable to allocate a second set of REs for the set of UCI types corresponding with a second set of frequency resources. The second circuitry may be operable to prepare one or more Physical Uplink Shared Channel (PUSCH) transmissions comprising the first set of REs and the second set of REs. A number of REs in the first set of REs may be different than a number of REs in the second set of REs.

Abstract: Future LTE systems will support massive carrier aggregation that necessitates transmission of a large number of acknowledgement signals (HARQ-ACKs) in response to downlink data transmitted over multiple component carriers. Described herein are methods and apparatus for efficiently transmitting HARQ-ACK and periodic channel state information (P-CSI) bits over the PUCCH (physical uplink control channel).

Abstract: Embodiments of a User Equipment (UE) to operate in accordance with a physical random access channel (PRACH) are disclosed herein. The UE may comprise hardware processing circuitry to determine a coverage enhancement category for the UE based on downlink channel statistics related to reception of downlink signals at the UE from an Evolved Node-B (eNB) and an uplink-downlink imbalance parameter related to uplink reception at the eNB. The hardware processing circuitry may be further to select, for use in a coverage enhancement mode, a PRACH preamble from a set of candidate PRACH preambles based on the determined coverage enhancement category for the UE. In some embodiments, at least some of the candidate PRACH preambles may span a different number of sub-frames.

Abstract: Devices and methods of receiving a PDCCH-less xSIB are generally described. A UE receive a xPBCH that occurs in a 0th or a 25th subframe and an ePBCH in an ePBCH transmission block. The ePBCH has the xSIB and is received on different Tx beams. The ePBCH spans consecutive symbols on the same subcarrier and with the same ePBCH symbol. The frame number, subframe number and symbol number of the ePBCH is dependent on a subframe number and symbol number of the xPBCH. The number of beams received for a particular symbol is dependent on a total number of beams, a beam sweeping time for the beams and a transmission periodicity of the xPBCH and ePBCH. The UE also uses different OCCs to demodulate a DMRS from different APs, in a same PRB as the ePBCH.

Abstract: A method for low overhead system information acquisition (LOSIA) is disclosed. The LOSIA method includes several techniques for transmitting common channels in a next generation Radio Access Technology (xRAT). Instead of transmitting system information in a periodic, static, cell-specific, wideband manner, the transmission is triggered by user equipment in an “on demand” manner. The LOSIA method allows the network to control the overhead, bandwidth, and periodicity, as well as other characteristics. The LOSIA method employs several different techniques to trigger the information upon which the network can act, for example, by transmitting different payloads depending on the received trigger.
