  • Publication number: 20240178962
    Abstract: A user equipment (UE) may support concurrent synchronization signal block (SSB) inter-frequency measurement without a measurement gap (MG). The UE may also, or alternatively, support concurrent SSB inter-frequency measurement in intra-band scenarios (e.g., where a target inter-frequency cell and serving cell are on the same band) and/or inter-band scenarios (e.g., where a target inter-frequency cell and serving cell are on the same band). The UE may report concurrent SSB based inter-frequency measurement as a NEEDFORGAP information element (IE), which may include one or more of a variety of parameters regarding UE measurement capabilities. Scheduling restrictions (e.g., restrictions to downlink and uplink communications) are also enabled based on UE measurement capabilities, including scheduling restriction for frequency range 1 (FR1), frequency range 2 (FR2), and cross frequency range scenarios.

  • Publication number: 20240179758
    Abstract: Systems and methods for determining a timing of a random access channel (RACH) occasion (RO) used to transmit a contention free random access (CFRA) preamble triggered by the receipt of an physical downlink control channel (PDCCH) order in a PDCCH are disclosed herein. A user equipment (UE) receives the PDCCH order and determines a timing offset value between the RO and a signal (e.g., a synchronization signal block (SSB), the PDCCH, a reference signal, etc.) to be used as a timing source. The UE also determines the arrival time of the signal to be used at the timing source. The UE then determines a time of the RO (during which the CFRA preamble will be transmitted) according to the arrival time and the timing offset value. Timing advance (TA) value(s) may also be accounted for as part of such a determination.

    Abstract: Techniques discussed herein can facilitate inter-cell interference mitigation. One example aspect is a user equipment (UE), configured to receive a network assistance indication associated with an interfering signal, where the interfering signal interferes with a physical downlink shared channel (PDSCH) transmission. A time resource allocation of the interfering signal is different than a time resource allocation of the PDSCH transmission. The UE is further configured to determine an interference and noise covariance estimation mechanism based on the network assistance indication then perform interference and noise covariance estimation based on the noise covariance estimation mechanism. The UE is further configured to perform mitigation of the interfering signal using a mitigation mechanism based on the interference and noise covariance estimation.

  • Patent number: 11997509
    Abstract: Methods and systems to activate beams for beam switching based on measurements of a downlink reference signal that is QCL Type-D with a downlink pathloss reference signal are disclosed. A UE may measure and report to a base station the RSRP of the reference signal that is QCL Type-D with a target downlink pathloss reference signal. Based on the reported RSRP measurements, the base station may activate the target pathloss reference signal to command the UE to update the pathloss measurements of the target pathloss reference signal for uplink power control of a beam corresponding to the target pathloss reference signal. The UE may determine whether the target pathloss reference signal is considered known for uplink power control based on the timing relationship among the reception of the reference signal from the base station, the transmission of the RSRP measurement of the reference signal, and reception of the activation command.

  • Publication number: 20240172018
    Abstract: Some aspects include an apparatus, method, and computer program product for radio resource management measurement prioritization for reduced capacity (RedCap) user equipment (UE). A RedCap UE may be use Half-Duplex Frequency Division Duplex (HD-FDD) for wireless communications. When performing communications with a network, the RedCap UE may make several measurements, including Reference Signal Received Power (RSRP), Signal to Interference and Noise Ratio (SINR), and Reference Signal Received Quality (RSRQ) measurements. To obtain these measurements, the RedCap UE may measure Synchronization Signal Block (SSB), Received Signal Strength Indicator (RSSI), and/or Channel State Information Reference Signal (CSI-RS) symbols. Difficulties may arise when a RedCap UE's serving cell signal timing is not synchronized with a neighboring cell. The RedCap UE may be configured to prioritize measurements over uplink transmissions.

  • 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.
