Abstract: Techniques are provided for mitigating inter-carrier interference (ICI) due to frequency multiplexed downlink channels with mixed numerologies. For example, a base station allocates, for a user equipment (UE), a first downlink (DL) channel and a second DL channel that are frequency multiplexed in a same bandwidth part (BWP) and have different channel numerologies The base station determines a guard band interval between the first DL channel and the second DL channel based on one or more characteristics of the different channel numerologies, transmits DL transmissions to the UE, over the first DL channel and the second DL channel, using the guard band interval between the first DL channel and the second DL channel.

Abstract: A method, UE and integrated circuit for reporting RSTD values to a network. A user equipment (UE) is configured to establish a connection to a network, the network comprising a first cell and a second cell. The UE receives a positioning reference signal from each of the first and second cells, determines a frequency band for each of the positioning reference signals, determines reference signal time difference (RSTD) values from measured time offsets between the positioning reference signals from the first and second cells, determines RSTD reporting values based on at least the RSTD values and the determined frequency bands and transmits an indication of the RSTD reporting values to the network.

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for scheduling intra-frequency measurements. Some embodiments are directed to a user equipment (UE). The UE includes processor circuitry and radio front circuitry. The processor circuitry can be configured to determine a collision signal status between an intra-frequency measurement signal and an uplink transmission signal. The processor circuitry can be further configured to determine a measurement gap status of the LIE. Moreover, the processor circuitry can be further configured to prioritize between the SSB measurement signal and the uplink transmission signal based on the collision signal status and the measurement gap status. Additionally, the processor circuitry can be further configured to perform a wireless measurement according to the prioritization between the intra-frequency measurement signal and the uplink transmission signal.

Abstract: Disclosed is a system and method that allows a user equipment (UE) to perform a wireless measurement. The method configures a characteristic of a channel-state information reference signal (CSI-RS) for tracking of the UE. Also disclosed is a system and method to perform radio resource management (RRM) testing. Testing can include: setting a power level of CSI-RS for tracking to a smaller value that a power level of another RRM reference signal; or setting a negative power offset value of the CSI-RS for tracking to a synchronization signal (SS) of the RRM reference signal; or setting a positive power offset value of the CSI-RS for tracking to a physical downlink shared channel (PDSCH) of the RRM reference signal.
