A wireless device can use a channel occupancy time (COT) to reserve a spectrum for sidelink positioning operations in a certain time interval. In some examples, multiple wireless devices can share the same COT for performing sidelink positioning and/or ranging operations using unlicensed or shared spectrum. Some aspects of the disclosure provide various processes for handling scenarios when channel access of the unlicensed spectrum is unsuccessful.

A method of enabling multi-connectivity in a wireless network includes predicting at least one of a RLF, a call drop, and a jitter based on a plurality of Key Performance Indicators (KPIs) associated with the UE and the wireless network, determining whether the UE is in one of a Dual Connectivity (DC) mode and a carrier aggregation (CA) mode, performing one of: adding a new secondary gNodeB (gNB) in response to determining that the UE is not in both the DC mode and the CA mode and converting the new gNB to a master gNB, converting an existing secondary gNodeB to a master gNodeB with one of an existing Master Cell Group (MCG) gNodeB and another gNodeB as the secondary gNodeB, in response to determining that the UE is in the DC mode, and converting an existing secondary cell to a primary cell.

A system that incorporates aspects of the subject disclosure may perform operations including, for example, monitoring performance parameters in a communications network, identifying a degradation in performance of one or more nodes of the communications network according the monitored performance parameters, and initiating corrective action to mitigate the degradation in performance of the one or more nodes of the communications network. Other embodiments are disclosed.

The present disclosure provides a method and a device in a communication node for wireless communications. The communication node first receives first information, the first information being used to determine a target time-frequency resource pool; and then monitors a first signaling; after that, when the first signaling is detected, the communication node receives a first radio signal; a first code block is used to generated the first radio signal; time-frequency resources occupied by the first signaling comprise a first time-frequency resource, while time-frequency resources occupied by the first radio signal comprise a second time-frequency resource; whether the first radio signal can be excluded from being used for combined decoding for the first code block is dependent on whether the first time-frequency resource belongs to the target time-frequency resource pool. The present disclosure manages to improve the flexibility of buffer configurations.

Methods, systems, and devices for wireless communications are described in which two or more UEs of a wireless communications system may establish a sidelink connection. A first UE that is initiating sidelink communications may evaluate whether the sidelink connection can support a quality of service (QoS) for a data flow prior to admitting the data flow. The first UE may evaluate a link quality with one or more other UEs that are to use the data flow on the sidelink connection, evaluate system congestion of time/frequency resources that are available for the sidelink connection, or any combinations thereof, and admit the data flow based on the evaluation. A link quality of the sidelink connection may be determined based on a type of communication associated with the data flow, such as unicast communications with one other UE, multicast communications with multiple other UEs, or broadcast transmissions to multiple UEs.

Disclosed are a method and apparatus for measuring wireless performance of a receiver of a wireless terminal, and a non-transitory computer readable storage medium. The method includes the following. A measured signal of a receiver to be measured is determined. Measured signals of other receivers except the receiver to be measured are zero. Multiple transmitted signals are determined based on the measured signals. The multiple transmitted signals are transmitted through multiple measurement antennas. When a bit error rate of the receiver to be measured does not equal a preset bit error rate, the measured signal is adjusted, determining the multiple transmitted signals based on the updated measured signal. When the bit error rate equals the preset error rate, a power of the measured signal is determined as the radiant sensitivity of the receiver to be measured.

Apparatuses, methods, and systems are disclosed for reporting power headroom (“PH”) information. One apparatus is configured with a first serving cell for PUSCH transmissions having a first SCS and a second serving cell for PUSCH transmissions having a second SCS larger than the first SCS. The apparatus has an uplink resource allocation for a first slot on the first serving cell, where the first slot overlaps in time with multiple second slots on the second serving cell, and has an uplink resource allocation for at least one of the multiple second slots that are overlapped by the first slot. A processor calculates PH information for the second serving cell for a first PUSCH scheduled on a first one of the multiple second slots and a transceiver transmits the PH information in an uplink transmission on the first slot.
