Abstract: Methods and apparatuses are disclosed for signaling unused channel occupancy time (COT) to the gNB for COT sharing among other UEs. Upon determining that a portion of the maximum COT (MCOT) provided to the UE will be unused, the UE can generate COT sharing information for transmission back to the gNB. The COT sharing information identifies a starting point and a duration (e.g., a number of consecutive slots) of the unused portion of the MCOT. This information is then encoded into configured grant uplink control information (UG-UCI) and transmitted to the gNB as part of the uplink transmission. In aspects, the unused portion may begin part-way through a slot. In this instance, a starting symbol of the unused portion or an ending symbol of the used portion may also be encoded into the uplink transmission. In this manner, unused COT is not wasted, but rather repurposed by the gNB.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing downlink transmission and interlace uplink transmission. For example, some aspects of this disclosure relate to a base station including a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor divides a plurality of candidate Synchronization Signal Block (SSB) positions in a time window into a plurality of groups and communicates, using the transceiver, information associated with the plurality of groups of candidate SSB positions to the UE. The processor further performs a listen-before-talk (LBT) procedure. In response to the LBT procedure being successful, the processor determines a first group of the plurality of groups and transmits, using the transceiver, one or more SSBs on one or more candidate SSB positions of the first group to the UE.

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: The exemplary embodiments relate to a user equipment (UE) delivering an indication of one or more uplink listen-before-talk (LBT) failures to a network. The UE may identify a predetermined condition corresponding to one or more uplink listen-before-talk (LBT) failures associated with a special cell (SpCell). The UE is triggered to provide an indication of uplink LBT failure associated with the SpCell to the network based on the predetermined condition. Next, the UE may determine a type of message that is to be used to deliver the indication of uplink LBT failure associated with the SpCell to the network. The UE may transmit the type of message including the indication of uplink LBT failure associated with the SpCell to the network. Subsequently, the UE may determine that the network received the indication of uplink LBT failure associated with the SpCell.

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.
