The present solution ensures that the UEs are able to make use of all the available reference signals that can be used in a cell for performing UE measurements, estimations or demodulations. That is achieved by indicating on a downlink common or shared channel, the MIMO mode settings associated with a specific network node. The indicated MIMO mode settings explicitly or implicitly indicate available common reference signals and/or dedicated reference signals to be used for said UE measurements, estimations or demodulations, which implies that measurements, estimations or demodulations can be performed based on said received indication.

A method of wireless communication includes, in response to a trigger event detected at a first base station, performing, by the first base station, a scan of a plurality of frequencies for a synchronization signal block (SSB) transmission from a second base station. The plurality of frequencies correspond to a plurality of global synchronization channel numbers (GSCNs) associated with the first base station and the second base station. The first base station is associated with a first coverage area that is at least partially within a second coverage area associated with the second base station. The method further includes transmitting, by the first base station, one or more SSBs having an SSB configuration that is based on a result of the scan.

A synchronization signal block (SSB) transmitted by a neighbor base station may interfere with a physical downlink shared channel (PDSCH) transmitted by a serving base station. A user equipment (UE) that receives both the SSB and PDSCH may mitigate the interference to improve an error rate of decoding the PDSCH. The UE may receive a first SSB including a first broadcast channel (BCH) from a second base station other than a serving base station. The UE may decode the first SSB. The UE may determine, based on the first SSB and the first BCH, that the PDSCH scheduled by the serving base station will overlap with a second SSB from the second base station. The UE may estimate a channel of the second SSB based on the decoded first SSB. The UE may remove a reconstructed second SSB from the PDSCH. The UE may decode the PDSCH.

A base station is disclosed, comprising: a processor; a memory coupled to the processor; a base station access radio coupled to the processor; a user equipment module, coupled to the processor, for providing a backhaul link for the base station; and a sniffing circuit coupled to the processor. The sniffing circuit further comprises: a radio receiver coupled to an amplifier and a filter, the amplifier and the filter both capable of being used across a plurality of frequencies; and a baseband processor coupled to the radio receiver, configured to convert a received signal from the radio receiver to a baseband frequency, to determine whether the received signal is one of a 2G, 3G, 4G, Wi-Fi, or 5G signal, to measure a signal strength of the received signal, and to identify a synchronization signal within the received signal.

Aspects of the present disclosure describe receiving, from at least one cell of a zone of multiple cells, a zone-specific signal related to the zone of multiple cells, wherein the zone of multiple cells operate using synchronized timing, acquiring, based on the zone-specific signal, a timing synchronization with a cell of the zone of multiple cells, and communicating with the cell based on the timing synchronization.

Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a serving cell and a processor communicatively coupled to the transceiver. The processor is configured to determine a reference signal sequence that comprises a primary synchronization signal (PSS) sequence and a secondary synchronization signal (SSS) sequence of a target cell. The processor is further configured to receive a signal sequence from the target cell and calculate an overall correlation value based on the reference signal sequence and the received signal sequence. The processor is further configured to determine that the overall correlation value is above a threshold and detect a synchronization signal block (SSB) of the target cell based on the received signal sequence. Finally, the processor is configured to establish a wireless connection with the target cell based on the SSB.

Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform to perform cell detection and measurement, e.g., in new radio (NR) unlicensed (NR-U). The UE may determine that a threshold condition related to missed reference signal opportunities is reached. In response, the UE may modify reference signal monitoring and/or measurement.

[Object] To make it possible to perform measurement reporting suitable for an environment in which the on/off state of a cell is switched. [Solution] There is provided a device including: an acquiring unit configured to acquire information indicating that a serving cell is scheduled to be in an off state; and a control unit configured to perform measurement reporting before the serving cell is in the off state.

The present disclosure provides techniques configuring channel state information (CSI) reporting for certain service types, such as the ultra-reliable low latency communications (URLLC) service type. In some cases, a UE may obtain information regarding a first set of channel state information (CSI) reporting configurations for a first service type separate from a second set of CSI reporting configurations for a second service type, receive a first downlink control information (DCI) scheduling a CSI report for the first service type on at least one physical uplink shared channel (PUSCH), generate at least one CSI report for the first service type based on one of the first set of CSI reporting configurations selected based on a field in the DCI, and transmitting the CSI report for the first service type on the PUSCH.

User equipment associated with a legacy network may utilize a bottom-to-top search technique to identify relevant control channel samples. Generating a control channel that is configured for the bottom-to-top search technique may lead to poor performance in a single-carrier waveform, which may be disadvantageous as networks move toward New Radio. In some aspects, described herein, a base station generates a control channel that is configured to minimize gaps in the control channel, and a user equipment performs a top-to-bottom search technique to identify relevant control channel samples. By using the top-to-bottom search technique, degradation of single-carrier waveforms is reduced and efficiency is improved.
