Abstract: Some embodiments include an apparatus, method, and computer program product for facilitating frequency hopping for physical uplink shared channel (PUSCH) communications in 5G wireless communication systems. When inter-slot and/or inter-repetition frequency hopping is used, user equipment (UE) may transmit a first portion of symbols in a first slot using a first transmission frequency indicated by a frequency domain resource allocation. The UE may transmit a second portion of symbols in a second slot using a second offset frequency. When intra-repetition frequency hopping is used and the symbols are segmented, the UE may disable the intra-repetition frequency hopping and transmit the segmented portion of symbols using a particular transmission frequency indicated by the frequency domain resource allocation. When intra-repetition frequency hopping is used and the symbols are non-segmented, the UE may apply frequency hopping to divide a portion of symbols for transmission within a repetition.

Abstract: Some aspects include an apparatus, method, and computer program product for facilitating control messaging for multi-beam communications in 5G wireless communication systems. Nodes of a 5G network may be generate Medium Access Control Control Elements (MAC CEs) to update User Equipment (UE) with different Component Carrier (CC) settings. The MAC CEs may update a list of CCs to reduce messaging overhead and latency. For example, a MAC CE may indicate an update for a Transmission Configuration Indication (TCI) state for a list of CCs. Similarly, a MAC CE may be used to update a spatial relation for a Sounding Reference Signal (SRS) resource set and/or a SRS resource corresponding to a list of CCs. A MAC CE may also be used to update multiple TCI codepoints having one or two TCI states in a multi-Transmission Reception Point (multi-TRP) scenario.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for cell identification (ID) and beam ID detections in new radio (NR). The detections comprise NR primary synchronization signal (PSS)/secondary synchronization signal (SSS)detection, PBCH DMRS detection, SS reference signal received power (RSRP)measurement, and slot/SS burst boundary timing acquiring. Various embodiments describe how to detect a cell ID and a beam ID in millimeter wave (mmWave) operation. Other embodiments describe further details regarding how to detect NR cell and beam ID during intra-frequency measurements.

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 network cell is connected to a user equipment (UE) that supports an independent measurement gap configuration. The cell establishes a connection to the UE, receives an indication that the UE supports an independent measurement gap configuration for new radio in an unlicensed spectrum (NR-U) and transmits measurement gap configuration information to the UE, wherein the UE configures a measurement gap pattern based on the measurement gap configuration information.

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.
