Abstract: A method for physical downlink control channel (PD-CCH) monitoring by user equipment (UE includes receiving a specification indicative of a monitoring pattern for a search space set including a plurality of slots. The monitoring pattern includes one or more monitoring spans within the search space set. Each of the one or more monitoring spans is associated with a set of parameters defining that particular monitoring span. The method includes selecting at least one monitoring span of the one or more monitoring spans. The method includes assigning the UE to monitor the at least one monitoring span. The method includes performing, by the UE, PDCCH monitoring during the selected at least one monitoring span.

Abstract: In an example computer-implemented method, a user equipment (UE) receives first configuration data including an indication of a search space set for monitoring a wireless network for an uplink cancellation command, and second configuration including an indication to activate monitoring of the wireless network for an uplink cancellation command. The UE further receives a first physical downlink control channel (PDCCH) including scheduling information for an uplink transmission. The UE monitors the wireless communications network for the uplink cancellation command in accordance with the search space set, and receives a second PDCCH from the wireless including the uplink cancellation command, where the uplink cancellation command includes an indication to cancel a first portion of the uplink transmission. The UE cancels a transmission of the first portion of the uplink transmission.

Abstract: User equipment (UE) includes processing circuitry, where to configure the UE for New Radio (NR) communications in an unlicensed spectrum, the processing circuitry is to decode a first configuration message received from a base station, the first configuration message including a channel quality indicator (CQI) table indication identifying a CQI table. A second configuration message is decoded, the second configuration message received separately from the first configuration message and including a modulation and coding scheme (MCS) table indication identifying an MCS table. DCI received via a PDCCH is decoded, the DCI providing a DL grant and an MCS index in the MCS table. DL information received via a PDSCH is decoded using modulation order and target code rate corresponding to the MCS index in the MCS table.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for a user equipment (UE) device that includes one or more processors configured to identify a search space for physical downlink control channel (PDCCH) candidates by: determining whether the search space is a group common search space or a UE specific search space; determining a number of PDCCH candidates per aggregation level (AL); determining a PDCCH monitoring periodicity and a PDCCH monitoring offset for the search space, each including a plurality of slots; determining monitored slots in the monitoring periodicity; determining, for each monitored slot, a monitoring pattern including a set of selected symbols; and determining a set of monitoring occasions corresponding to the set of selected symbols in each monitored slot of each monitoring periodicity. The one or more processors are configured to decode downlink signals received in the set of monitoring occasions to search for PDCCH information for the UE.

Abstract: Technology for a user equipment (UE) operable to determine a transport block size (TBS) is disclosed. The UE can determine a number of assigned resource elements (REs) in one or more symbols for a transport block. The UE can determine a reference number of REs per physical resource block (PRB) in the transport block based on a reference number of REs for the transport block corresponding to each PRB and an assigned number of PRBs for the transport block. The UE can determine a TBS for the transport block based at least on the reference number of REs per PRB in the transport block. The UE can encode information in a selected transport block for transmission via a physical uplink shared channel (PUSCH) to a Next Generation NodeB (gNB) in accordance with the TBS determined at the UE.

Abstract: An apparatus for use in an eNB, the apparatus includes circuitry to generate an assignment of one or more interlaces to a UE within a cell managed by the eNB, where the one or more interlaces are selected from a total number of interlaces, and an interlace of the total number of interlaces may include multiple resource blocks spanning within a system bandwidth. The circuitry included in the apparatus is further to encode the assignment by a bit string including one or more bits, which may be a bitmap or an encoding bit string. The circuitry included in the apparatus is further to transmit the bit string to the UE. Other embodiments may also be described and claimed.

Abstract: Methods and systems are provided for communicating in a wireless network based on a prioritization status. User equipment can receive a first signal that includes an indicator. The UE can determine a prioritization status for a second signal based on the prioritization indicator. The UE can communicate, with one or more radio access networks (RANs) of a network, the second signal, where the timeline of the second signal can be out of order respective of other signals communicated by the UE and the wireless network. The second signal can include data transmitted by an ultra-reliable low latency communication (URLLC) service. The UE can communicate the second signal out of order with respect to one or more additional signals. The UE, based on the indicator, can communicate hybrid automated repeat request (HARQ) feedback before a HARQ feedback timeline of a non-urgent transmission.

Abstract: Systems, devices, and techniques for controlling uplink transmissions including cancelling previously scheduled transmissions are described. A described technique includes receiving, by a user equipment (UE), a configuration information that provides a search space set configuration associated with a control resource set (CORESET) to monitor for an uplink cancellation indication; receiving, by the UE, scheduling information that schedules one or more uplink transmissions; monitoring, by the UE via a physical downlink control channel (PDCCH), for the uplink cancellation indication based on the configuration information; receiving, by the UE via the PDCCH, a downlink control information (DCI) message that comprises the uplink cancellation indication; and cancelling, by the UE, at least part of the one or more uplink transmissions in response to the uplink cancellation indication.
