RATE MATCHING BETWEEN UPLINK AND DOWNLINK

Abstract:

Methods, systems, and devices for wireless communications are described. For example, a method for wireless communications at a wireless device may include determining a rate matching configuration for a first channel (e.g., an uplink channel) associated with a second channel (e.g., a downlink channel). A wireless device may determine rate matching resources of an uplink channel based on the rate matching configuration. The wireless device may determine rate matching resources of a downlink channel based on the rate matching configuration. The wireless device may transmit a first message on the uplink channel or the downlink channel, respectively, where the transmitted channel includes the rate matching resources. The wireless device may receive a reference signal on one or more resources of the downlink channel or the uplink channel, respectively, where the one or more resources of the respective channel correspond to the rate matching resources on the transmitted channel.
