Abstract: Sub-band (SB) indications and listen-before-talk (LBT) outcomes may be used to adjust communications between devices such as wireless terminals and base stations. For example, a wireless terminal may receive SB indications including SB configurations and/or LBT outcomes of a base station, and other information such as a remapped CORESET. Similarly, a terminal may determine that a physical resource block (PRB) is invalid based at least in part on whether the PRB overlaps with a guard band. The terminal may be arranged to adjust its searches and transmissions based on received SB indications, and to provide the base station with LBT outcomes of the terminal.

Abstract: An electronic device including a transceiver to communicate with a network; and circuitry. The circuitry is configured to perform beam failure detection on a monitored cell; detect a beam failure on the monitored cell; determine at least one new set of candidate beam reference signals (CB-RSs) from at least one set of CB-RS configured for the device; determine if any CB-RS in the at least one new set of CB-RSs meets a criterion, and in a case that any CB-RS in the at least one new set of CB-RSs meets the criterion: select a beam corresponding to a CB-RS in the new set that meets the criterion as the new beam, and indicate the selected new beam to the network; and in a case that no CB-RS in the new set of CB-RS meets a criterion, indicate to the network that no CB-RS in the new set meets the criterion.

Abstract: The present application describes a WTRU including a non-transitory memory including instructions stored thereon for re-establishing a remote radio control (RRC) connection with a base station. The apparatus also includes a processor capable of executing instructions of determining, based upon a measurement in an active downlink bandwidth part (DL BWP), to initiate a random access channel (RACH) procedure. The processor also executes instructions of switching to a default uplink bandwidth part (UL BWP). The processor also executes instructions of initiating the RACH procedure. The process further executes instructions of transmitting a RA preamble using one of the RACH resources configured for the default UL BWP. The processor even further executes instructions of receiving a RA response. The processor yet even further executes instructions of switching from the default UL BWP to either an active UL BWP or another active UL BWP after re-establishing the RRC connection.

Abstract: A wireless device, such as user equipment (UE) or other apparatus, like may use a transparent mode operation in which the device is not aware of the operation mode of abase station, such as a gNB or other transmission and receive point (TRP), via the use of configurations for Frame Based Equipment (FBE) and Load Based Equipment (LBE) operating modes. A base station may initiate a Channel Occupancy Time (COT) that is an FBE COT or an LBE COT, in which the wireless device follows FBE or LBE procedures accordingly. A variety of criteria may be applied in determining whether to use FBE or LBE procedures, and to switch between them. A network may use indicate the intention to switch operation mode and may do so via implicit or explicit indications. Similarly, a wireless device may autonomously switch operation mode, and may indicate the selected mode to the network.

Abstract: A wireless transmit/receive unit (WTRU) may receive a tracking reference signal comprising resources located in one or more slots. The resources may be located in one or more symbols used for receiving a demodulation reference signal. The one or more symbols in which the resources of the tracking reference signal are located may be within a first five symbols in each of the one or more slots. At least one resource of the received tracking reference signal may be frequency multiplexed with the demodulation reference signal.

Abstract: Methods and apparatuses are described herein for transmission priority, collisions, and sharing in the COT by frame based equipment (FBE). In accordance with one embodiment, a wireless communications device such as an FBE, may conduct two stage channel sensing to avoid collision between other FBEs nodes. The wireless communications device may adjust the energy threshold to reflect a channel access priority. The FBE may conducting continuous and non-continuous second stage channel sensing. The FBE may perform enhanced two stage channel sensing to exploit the remaining portion of the COT. The FBE may store a configuration for the second stage of channel sensing for both the downlink (DL) and uplink (UL).

Abstract: The present application at least describes a method for obtaining channel access in a network. The method includes a step of selecting, via a gNodeB, a spatial filter from a first set of spatial filters to perform listen before talk (LBT). The method includes a step of detecting, via the gNodeB, a channel in an idle state. The method also includes a step of obtaining, a directional channel occupancy time (COT) in the channel in a direction of the selected spatial filter. The method also includes a step of transmitting, to a node, a channel access indicator transmission (CAI-T) on a beam in the cot via a spatial filter of a second set of spatial filters. The method further includes a step of receiving, from the node, a channel access indicator response (CAI-R). The method further includes a step of sensing, via short channel sensing and via the spatial filter or another spatial filter of the second set of spatial filters, the channel is clear. The method even further includes a step of sending, via the channel, information to the node using one or more spatial filters of the second set of spatial filters. Other embodiments of this aspect include corresponding computer systems, apparatus, and computer programs recorded on one or more computer storage devices, each configured to perform the actions of the methods.
