METHODS AND SYSTEMS FOR FILTER FREQUENCY RESPONSE SHIFT COMPENSATION FOR WLAN TRAFFIC
Systems and techniques are described that are directed to filter frequency response shift compensation, including compensating for shifting in the rejection band of the filter. Compensation for the shifting in the rejection band can include applying a pre-distortion to attenuate edge resource units (RUs), and applying PHY Protocol Data Unit (PPDU) scheduling schemes. For example, a PPDU scheduling scheme reduce bandwidth in the channel, thereby dropping the out of band RUs. Front ends provide feedback to a respective radio, which allows that radio to apply the appropriate pre-distortion. The front ends can include one or more filters enabling frequency domain coexistence between collocated radios operating in the differing Wi-Fi bands, and a coupler that provides the feedback indicating the frequency response shift to a radio. The radio can then apply a digital pre-distortion to compensate for the shifting in the rejection band.
TRACKING REFERENCE SIGNAL CONFIGURATION FOR SINGLE FREQUENCY NETWORK COMMUNICATIONS
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message indicating a resource set that includes one or more resources or a resource configuration for two or more time resources for reference signal reception from at least two transmission/reception points (TRPs) in accordance with a single frequency network (SFN) configuration. The UE may receive a first reference signal from the first TRP and a second reference from the second TRP in the indicated resources. The UE may perform a channel estimation for an SFN channel associated with the at least two TRPs in accordance with the control message. The channel estimation may be based on the first and second reference signals. The UE may communicate with at least one of the first TRP and the second TRP in accordance with the channel estimation.
