  • Publication number: 20240155696
    Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc.) can operate to configure a hand over (HO) or a primary secondary cell (PSCell) addition based on a channel state information reference signal (CSI-RS) based contention free random access (CFRA) procedure. A CSI-RS rough timing of a CSI-RS position can be determined based on a synchronization signal block (SSB) associated with a CSI-RS or a serving cell timing. A CFRA transmit timing can be determined based on the CSI-RS rough timing or a CSI-RS fine timing that is derived from a timing and frequency (T/F) tracking operation on the CSI-RS. Reference signal receive power (RSRP) measurement(s) can be made on the CSI-RS for performing the CSI-RS based CFRA procedure with transmissions according to the CSI-RS transmit timing of the CSI-RS that satisfies an RSRP threshold.

  • Publication number: 20240155398
    Abstract: Systems and methods for analyzing a validity of an early measurement report (EMR) measurement result are described herein. A base station may configure a threshold value for EMR result validity and receive, from a user equipment (UE), a first measurement value corresponding to a first time at or before expiration of a timer associated with idle mode or inactive mode measurements. The base station receives, from the UE, a second measurement value corresponding to a second time when a radio resource control (RRC) connection setup or resume procedure starts. The base station then determines, based on a comparison of the threshold value to a difference between the first measurement value and the second measurement value, whether the EMR result is valid.

  • Patent number: 11979760
    Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.

The CORESET data may be configured to support the broadcast of off-raster SSBs in wireless communication systems. In some embodiments, the in-raster SSB and the off-raster SSB may share the same CORESET. In this case, the IAB may modify a bit pattern of configuration table corresponding to the shared CORESET and broadcast the in-raster SSB and the off-raster SSB while including the modified bit pattern.
