Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a cellular station. The controller uses one or more first preambles within a PRACH time-frequency resource to perform a synchronous transmission on the PRACH to the cellular station via the wireless transceiver, or uses one or more second preambles within the PRACH time-frequency resource to perform an asynchronous transmission or a synchronous transmission on the PRACH to the cellular station via the wireless transceiver.

Abstract: Aspects of the disclosure further provide an apparatus and a method for wireless communication. The apparatus includes processing circuitry that receives, from a base station (BS), a downlink (DL) grant scheduling an uplink (UL) transmission to the BS. The DL grant indicates a first type of channel access procedure for the UL transmission. The processing circuitry further receives channel occupancy information for a channel occupancy that is initiated by the BS. The processing circuitry switches, from the first type of channel access procedure, to a second type of channel access procedure for the UL transmission according to the first type of channel access procedure and the channel occupancy information.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The apparatus may be a UE. The UE determines to transmit a preamble sequence to a base station at a random access occasion in a random access procedure when the UE is in a connected state. The UE determines that the random access occasion is in a same predetermined time period as an uplink channel or a sounding reference signal that is scheduled to be transmitted to the base station. The UE refrains from transmitting the preamble sequence or refraining from transmitting the uplink channel or the sounding reference signal.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, a timing advance command on a first downlink component carrier in a first time slot measured from a perspective of a first uplink component carrier. The UE determines a number of slots between the first time slot and a second time slot measured from the perspective of the first uplink component carrier based on at least one of: a first time duration allocated to the UE for decoding a downlink data channel, and a second time duration allocated to the UE for preparing an uplink data channel. The UE applies a timing advance based on the timing advance command on the first uplink component carrier or a second uplink component carrier in the second time slot.

Abstract: Aspects of the disclosure provide apparatuses and methods for wireless communications. One apparatus includes processing circuitry that selects one or more first available radio link monitoring reference signal (RLM-RS) samples from a plurality of received RLM-RS samples based on signal qualities of the one or more first available RLM-RS samples. The one or more first available RLM-RS samples are received within a first evaluation period. The processing circuitry determines whether a total number of the one or more first available RLM-RS samples is less than a target number. When the total number of the one or more first available RLM-RS samples is determined to be less than the target number, the processing circuitry determines a second evaluation period that is greater than the first evaluation period, and performs an RLM procedure in an unlicensed band within the second evaluation period.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, in an active down-link bandwidth part, a random access response from a base station indicating an up-link resource in an active up-link bandwidth part for transmitting a random access message. The UE generates the random access message based on a numerology of the active up-link bandwidth part. The UE transmits the random access message at the up-link resource in the active up-link bandwidth part.
