Abstract: Technology for an apparatus of a user equipment (UE), operable to perform a random-access procedure using a UE-specific control resource set (CORESET) is disclosed. The UE can decode a 5 message, received from the next generation node B (gNB), to perform a contention free random-access (RA) procedure. The UE can encode a random-access channel (RACH) preamble for transmission to the gNB using one or more UE-specific CORESET. The UE can decode a random-access response (RAR) received from the gNB in response to the RACH preamble transmission using the one or more UE10 specific CORESET.

Abstract: Briefly, in accordance with one or more embodiments, apparatus of an evolved NodeB (eNB) comprises circuitry to configure one or more parameters for a 5G master information block (xMIB). The xMIB contains at least one of the following parameters: downlink system bandwidth, system frame number (SFN), or configuration for other physical channels, or a combination thereof. The apparatus of the eNB comprises circuitry to transmit the xMIB via a 5G physical broadcast channel (xPBCH) on a predefined resource, the xPBCH comprising a xPBCH. The xPBCH may use a DM-RS based transmission mode, and a beamformed xPBCH may be used for mid band and high band.

Abstract: Systems, devices, and techniques for beamforming in wireless communication systems are described. A described technique performed by a user equipment (UE) includes monitoring a downlink reference signal from a base station; transmitting, via a physical uplink shared channel (PUSCH) associated with a hybrid automatic repeat request (HARQ) process number, a beam failure recovery request (BFRQ) in response to a change in a quality of the downlink reference signal, wherein the BFRQ comprises new beam information; receiving, by the UE, a downlink control information (DCI) message to trigger a PUSCH transmission corresponding to the HARQ process number; and transmitting, by the UE after at least a predetermined number of symbols from a last symbol of a physical downlink control channel (PDCCH) reception containing the DCI message, information via a PUCCH in accordance with the new beam information. The UE can apply the new beam information to uplink and downlink channels.

Abstract: Systems, devices, and techniques for physical uplink control channel (PUCCH) resource grouping in wireless communication systems that include transmission and reception points (TRPs) are described. A described technique performed by a user equipment (UE) includes receiving a PUCCH resource group configuration associated with TRPs, including a first TRP and a second TRP; and performing PUCCH transmissions to the TRPs in accordance with the PUCCH resource group configuration. The PUCCH resource group configuration can include a configuration for a first group of PUCCH resources associated with the first TRP and a second group of PUCCH resources associated with the second TRP.

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: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of physical downlink control channel (PDCCH) monitoring in different search spaces sets independently from one another in order to manage different services optimally. A processor of the network device can be configured to receive physical downlink control channel (PDCCH) candidates of a PDCCH in a slot for channel estimation across search spaces of the slot. Different priorities can be determined among the PDCCH candidates in the slot based on a priority rule. Then a number of PDCCH candidates can be skipped/dropped from monitoring based on the different priorities of the PDCCH candidates to ensure that a threshold level of blind decoding operations across a plurality of slots of the PDCCH is being satisfied. The UE can monitor a portion of the PDCCH candidates while concurrently skipping another.
