Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing mechanisms for exchanging a searcher number between an electronic device (for example, a UE) and a network for cell detection and measurement. For example, some embodiments relate to an electronic device including a transceiver and a processor communicatively coupled to the transceiver. The processor determines a searcher number associated with the electronic device. The searcher number is greater than two. The processor further transmits, using the transceiver, a signal to the network, where the signal includes an indication of the searcher number.

Abstract: A base station (BS) configures a user equipment (UE) with parameters for channel access operations on a shared channel. The BS transmits to the UE a first configuration for a BS-initiated fixed frame period (FFP) (BS-FFP) and a second configuration for a UE-initiated FFP (UE-FFP), wherein the BS-FFP overlaps the UE-FFP, schedules an uplink (UL) transmission during the UE-FFP and when there is no downlink (DL) transmission in the BS-FFP, receiving the UL transmission from the UE during the BS-FFP.

Abstract: A user equipment (UE) may attempt to access a base station of a network. The UE receives, from the base station of a wireless network, a broadcast including a system information block (SIB) identifying a plurality of random access channel (RACH) sub-bands of an uplink (UL) bandwidth and which of the plurality of RACH sub-bands includes physical random access channel (PRACH) resources. The base station selects one of the plurality of RACH sub-bands for a PRACH transmission and selects a preamble from the selected RACH sub-band and transmit the preamble to the base station to initiate a RACH procedure.

Abstract: A base station maps physical downlink control channel (PDCCH) candidates and PDCCH transmissions for multi-transmission reception point (TRP) operation. The base station determines that a control resource set (CORESET) is to be shared by at least a first TRP and a second TRP corresponding to a cell of a network, performs resource element group (REG) bundle to virtual REG bundle mapping on a per TRP basis, wherein multiple REG bundles are indexed on the per TRP basis, performs virtual REG bundle interleaving across the first TRP and the second TRP, performs control channel element (CCE) to interleaved REG bundle mapping and transmits downlink control information (DCI) using the CORESET, wherein the CORESET is configured based on, at least, the CCE to interleaved REG bundle mapping.

Abstract: A user equipment (UE) performs a multi-level Downlink Control Information (DCI) monitoring operation. The UE monitors an Anchor-search space set (SSS) of a first resource block (RB) set for downlink control information (DCI) and, when the Anchor-SSS includes DCI, monitors at least one Subordinate-SSS of a second RB set based on at least the DCI detected on the Anchor-SSS.

Abstract: Embodiments include a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. The operations include receiving a plurality of control resource sets (CORESETs), selecting at least one reference signal (RS) corresponding to at least one activated transmission configuration indicator (TCI) state in a CORESET, analyzing the at least one RS and determining beam failure detection (BFD) or radio link monitoring (RLM) based on the at least one reference signal selected.

Abstract: Embodiments include a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. The operations include receiving a plurality of control resource sets (CORESETs), selecting a CORESET, wherein the CORESET includes one or more active transmission configuration indicator (TCI) states and determining a default beam or a pathloss reference signal (RS) based on a TCI state. Further operations include receiving a beam indication for a physical downlink control channel (PDCCH), wherein the PDCCH is received via one or more CORESETS, each having a plurality of TCIs, determining if the PDCCH collides with a second signal and determining whether to (a) drop the PDCCH or the second signal or (b) base a quasi co-location (QCL) of one of the PDCCH or the second signal on a QCL of the other one of the second signal or the PDCCH.

Abstract: Systems and methods for measuring at and reporting by a target user equipment (UE) of one or more positioning signals sent from one or more assisting UEs to the target UE are disclosed herein. The target UE may receive a positioning signal from an assisting UE according to a communication received at the target UE. The target UE may proceed to perform a positioning measurement using the positioning signal received from the target UE. The positioning measurement may be used by the target UE to estimate its own position, or the positioning measurement may be sent to another entity within a wireless communications system to be used in estimating the physical position of the UE. The handling of multiple received positioning signals from various sources, and the handling of situations where, for example, a transmission reception point (TRP) and an assisting UE may schedule overlapping positioning signals, ate also discussed.
