Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message indicating that a control resource set for a downlink control channel is associated with a plurality of demodulation reference signal (DMRS) ports. The UE may determine, based at least in part on the configuration message, that a first set of DMRS resource elements in a first symbol of the control resource set correspond to a first DMRS port of the plurality of DMRS ports and a second set of DMRS resource elements in a second symbol of the control resource set correspond to a second DMRS port of the plurality of DMRS ports. The UE may decode the downlink control channel based at least in part on the determining.

Abstract: In some designs, UE receives an active BWP SCS value of an active BWP SCS that is 120 kHz or higher, and a reference SCS value of a reference SCS that is the same or lower than the active BWP SCS, and determines a number of consecutive slots in the active BWP associated with the same SFI based on the active BWP SCS value and the reference SCS value. UE and BS communicate on slot(s) of the active BWP based on the active BWP SCS value and the reference SCS value. In some designs, a multi-slot SFI configuration is defined for multiple SFIs.

Abstract: Methods, systems, and devices for transmit power control for positioning using non-serving cells are described. A user equipment (UE) may determine that an uplink reference signal may be associated with a positioning procedure. In some cases, the positioning procedure may include transmission, by the UE, of the reference signal to a non-serving cell, which may be farther away from the UE than a serving cell. The UE may determine an absence of a parameter associated with a transmit power for transmitting the reference signal. Based on the absence, the UE may determine the transmit power based on parameters received from a serving cell, based on configuration information, based on a message intercepted from the cell other than the serving cell, or based on other considerations or information.

Abstract: A UE in cellular communication system may be equipped with multiple User Services Identity Modules (USIMs) to support multiple service subscriptions. The UE having multiple service subscriptions may obtain services from one or more wireless networks with each of the subscriptions. When the UE having multiple service subscriptions needs to make an emergency call, the UE may identify and determine a service subscription to make the emergency call, so that the emergency call can be successfully made. The UE may be implemented with a communication processor (modem) and an application processor (AP). Some information that is useful to identify a service subscription more suitable for the emergency call may be available only at the communication processor. Enhanced techniques for identifying and determining a service subscription to make the emergency call from the multiple service subscriptions through interaction between the communication processor and the application processor are disclosed.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may configure one or more first sets of resources of a radio frequency spectrum band associated with a first pathloss mode, and may configure one or more second sets of resources associated with a second pathloss mode. Each set of resources may be configured with some transmission timing parameters and frame structure, such that a transmission time interval (TTI) associated with the first pathloss mode may be different from the TTI associated with the second pathloss mode. The wireless device may communicate with a second wireless device using the one or more first sets of resources based on identifying a pathloss value is below an identified pathloss threshold. Additionally, the wireless device may communicate with a third device using the one or more second sets of resources based on identifying a pathloss value satisfies the identified pathloss threshold.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) and a network entity may utilize multi-port mobility reference signals to assist with spatial based mobility procedures. The UE may receive a reference signal that is associated with multiple antenna ports. The UE may measure a multi-dimensional channel response based on the reference signal. The multi-dimensional channel response may be associated with measured channel metrics corresponding to the multiple antenna ports. The UE may transmit a report that includes a channel measurement vector based on the multi-dimensional channel response. The channel measurement vector may indicate multiple measured channel metrics for one or more dimensions of the multi-dimensional channel response. The network entity may transmit a message that indicates one or more metrics associated with mobility management for the UE based on the report that indicates the channel measurement vector.

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.
