Abstract: Methods, systems, and devices for wireless communications are described. Feedback information associated with decoding downlink information may be reported in a first stage and a second stage. A size of the second stage may be restricted by an upper limit associated with an available set of uplink resources for transmitting the feedback information. Limiting the size of the second stage may include reducing a size of second information generated for the second stage, yielding third information for the second stage. The third information may be transmitted with first information generated for the first stage. Limiting the size of the second stage may also include generating second information having a reduced size based on determining that the upper limit may be exceeded. The reduced-size second information may be transmitted with the first information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), served by a cell of a base station, may identify a time division duplexing (TDD) configuration for the first cell, where the TDD configuration includes a symbol pattern for a slot. The base station may determine an overlap between a downlink symbol or a flexible symbol and an uplink symbol during symbols of the slot based on a TDD configuration. The first UE may receive a configuration for transmitting a cross-link interference (CLI) sounding reference signal (SRS) to a second UE according to the configuration. The second UE may measure the CLI SRS and report the measurement.

Abstract: Design of a remote interference management (RIM) framework is disclosed. Each victim base station may maintain an aggressor list of remote base stations providing interference to the victim. The victim base station signals the aggressor base stations to apply RIM mitigation mechanisms for reducing the remote interference. The victim may then maintain and update the aggressor list based on estimation and measurements of RIM reference signals detected from the aggressor cells.

Abstract: Aspects of the disclosure are related to identifying whether an apparatus (e.g., base station, access point, etc.) is transmitting using a CRS based transmission scheme or a UE-RS based transmission scheme. Such detection may be necessary for PDSCH interference cancellation (IC) of a neighboring cell since a UE may not know which transmission scheme is used by the neighboring cell. For instance, the UE may know the transmission scheme of the serving cell, but the UE may not know the transmission scheme of a neighboring non-serving cell. As such, aspects of the disclosure provide for a blind detection algorithm to identify or determine a transmission mode or transmission scheme of a neighboring cell to then apply interference cancellation (IC) to an interfering signal received from the neighboring cell.

Abstract translation: 本公开的方面与识别装置（例如，基站，接入点等）是否正在使用基于CRS的传输方案或基于UE-RS的传输方案进行传输有关。 这样的检测对于相邻小区的PDSCH干扰消除（IC）可能是必要的，因为UE可能不知道相邻小区使用哪种传输方案。 例如，UE可以知道服务小区的传输方案，但是UE可能不知道相邻非服务小区的传输方案。 因此，本公开的方面提供盲检测算法来识别或确定相邻小区的传输模式或传输方案，然后将干扰消除（IC）应用于从相邻小区接收的干扰信号。

Abstract: Techniques are provided for frequency spectrum sharing that allows secondary operators to access a frequency band of a primary operator without interfering with the primary operator's use of the band, while ensuring service continuity for devices of the secondary operators. For example, there is provided a method that may involve identifying an outage on a first channel of a plurality of channels of a spectrum, wherein each of the plurality of channels is allocated to one of a plurality of operators. The method may involve migrating all mobile stations in communication over the first channel of the plurality of channels to at least one other channel of the plurality of channels during the outage.

Abstract: Systems, methods, and mechanisms for modifying or cancelling uplink transmissions using dynamic slot format validation are provided. One aspect of the present disclosure includes a method of wireless communication performed by a user equipment (UE). The method of wireless communication includes determining that an uplink (UL) transmission is configured for a first time period; monitoring for a slot format indicator (SFI) validation associated with the first time period; and determining, based at least in part on the monitoring, whether to transmit the UL transmission during the first time period.

Abstract: Aspects of the present disclosure provide techniques for physical uplink shared channel transmissions sent using multiple frequency domain resource allocations (FDRAs). According to certain aspects, a user equipment (UE) determines at least a first part frequency domain resource allocation (FDRA) and a second part FDRA, transmits a first part of a physical uplink shared channel (PUSCH) on the first part FDRA with a first precoder, and transmits a second part of the PUSCH on the second part FDRA with a second precoder.

Abstract: User Equipment (UE) receives, from a base station (BS), at least one resource block (RB). The RB includes at least one reference signal (RS) resource element (RE) of a first physical channel of the UE. The UE estimates a channel quality of a second physical channel of the UE as a function of the at least one RS RE. In some examples, the BS associates the transmission of a first physical channel reference signal (RS) and the transmission of a second physical channel RS. The BS then signals, BS to the UE, the association between the first physical channel reference signal and the second physical channel reference signal.

Abstract: Various aspects of the present disclosure generally relate to frequency hopping within a virtual BWP. In some aspects, a UE may determine a virtual bandwidth part (BWP) in which to frequency hop from a first narrow BWP to a second narrow BWP by a frequency offset. The virtual BWP may have a same subcarrier spacing as the first narrow BWP and a larger bandwidth than the first narrow BWP. The UE may perform communication based at least in part on frequency hopping within the virtual BWP. Numerous other aspects are provided.
