Abstract: Aspects of the technology described herein are directed towards using generic control information in a three-party wireless communication system to schedule a data transmission and reception of the data transmission. A scheduler node transmits the generic control information, comprising identification information that identifies a user equipment device as a transmitter node, and scheduling information that schedules a data transmission. For unicast data transmissions, the generic control information further identifies a receiver node, and can schedule transmission of an ACK/NACK from the receiver node corresponding to receiving the data transmission. A control procedure can be configured in a user equipment device by linking a channel configuration dataset to a resource configuration dataset, which in turn is linked to a channel transmit and receive configuration dataset. Reconfiguration is achieved by changing the linking(s) between one or more different available datasets.

Abstract: Aspects of the subject disclosure may include, for example, receiving, by a first radio module at a first location, a wireless signal, to obtain a first received RF signal. The wireless signal includes information originating at a remote transmitter and conveyed via a wireless channel. An envelope of the first received RF signal is detected by the first radio module without requiring a local oscillator, to obtain a first baseband signal. The first baseband signal may be filtered and/or amplified, after which it is provided to a processor. The processor also obtains a second digital signal from a second radio module receiving the wireless signal at a second location and determines an estimate of the information originating at the remote transmitter according to the first and second signals. Other embodiments are disclosed.

Abstract: One subscriber identity module (SIM) can transmit data in active mode while another SIM is in an idle mode. However, paging for the SIM in idle mode can occur based on a discontinuous reception configuration (DRX) cycle of the active SIM. For example, when the DRX of the active SIM indicates that the active SIM is in an idle state, then the SIM that is currently in an idle state can send messages and vice versa. The DRX cycle information can be exchanged between a first core network and a second core network. Each core network can belong to the same or different mobile network operator and can have separate radio access networks (RAN) or share the RAN. The DRX cycle information and/or a time-division multiplexing (TDM) pattern can be exchanged over the air via a system information broadcast message.

Abstract: The described technology is generally directed towards multidimensional grid sampling for radio frequency power feedback. A mobile device can sample radio frequency signal power at multiple sample points, and can send sample values to a base station. The multiple sample points can be defined with reference to a grid having a first dimension and a second dimension, such as time and frequency, or delay and Doppler. A variety of techniques are provided to define the multiple sample points.
