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.

Abstract: Systems, methods, and apparatuses disclosed herein can operate on an unlicensed spectrum. These systems, methods, and apparatuses can perform a first listen-before-talk (LBT) operation of a LBT protocol in a first slot from among multiple slots to determine whether the unlicensed spectrum is unoccupied. Thereafter, these systems, methods, and apparatuses can transmit an uplink (UL) transmission in other slots from among the plurality of slots in response to the unlicensed spectrum being unoccupied. Otherwise, these systems, methods, and apparatuses can perform a second LBT operation in a second slot from among the plurality of slots in response to the unlicensed spectrum being occupied.

Abstract: Systems, devices, and techniques for wireless communications are described. A described technique includes receiving, by a user equipment (UE) from one or more Transmission and Reception Points (TRPs), a physical downlink shared channel (PDSCH) transmission; determining, by the UE for a physical uplink control channel (PUCCH) carrying hybrid automatic repeat request-acknowledgement (HARQ-ACK), a TRP index in accordance with a control resource set (CORESET) scheduling the PDSCH transmission; and transmitting, by the UE via the PUCCH, HARQ-ACK information based on the receiving of the PDSCH transmission in accordance with the TRP index.

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: Resource allocation is provided for an integrated access and backhaul (IAB) network, such as a distributed unit (DU) of an IAB. Methods and systems include configuring one or more resources to allocate time-domain or frequency domain availability/utilization. Configurations of resources can be aligned between one or more nodes such that resource availability of a first node can be coupled to resources of a second node. Allocated resources can include uplink, downlink, and flexible resources. Allocated resources can be indicated as not available, hard, or soft resource types. A configuration pattern can indicate a sequence of time-domain resource or frequency domain resource availability of a DU in the IAB network.
