Abstract: A base station may make more efficient use of resources by transmitting data in a control region of a slot in addition to a data region. In order to avoid performance loss, the base station may adjust the data transmission in the control region in comparison to a data transmission in a data region and may signal an indication to a UE to assist the UE in receiving the data transmission in the control region. An apparatus for wireless communication at the UE receives the indication from the base station regarding the data transmission in the control region and uses the indication to perform rate matching or demodulation of the data transmission in the control region. The indication may indicate any of a different MCS/rank/TPR, a reduced MCS/rank/TPR, an MCS/rank/TPR delta, a control span for a group of UEs, and a starting symbol for the data transmission. The indication may also indicate that there is no data transmitted on resources in the control region.

Abstract: Wireless communications systems and methods related to reusing long-term evolution (LTE) resources for new radio (NR) system operations are provided. A UE receives, from a base station, a reference signal configuration of a first network of a long-term evolution (LTE) radio access technology (RAT). The UE and the base station are associated with a second network of another RAT. The reference signal configuration indicates at least a number of antenna ports associated with a reference signal of the first network. The UE determines a location of the reference signal associated with the reference signal configuration and receives, from the base station, a data signal of the second network based at least on the location of the reference signal of the first network.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify time and frequency resources for a physical downlink shared channel (PDSCH) to be transmitted to a user equipment (UE) in a first transmission time interval (TTI). The base station may transmit configuration information for a control channel search space set in a second TTI. The second TTI may precede the first TTI. The configuration information may include an indication of an absence of a physical downlink control channel (PDCCH) transmission to send in the control channel search space set indicating the identified time and frequency resources for the PDSCH, and a set of time and frequency resources for the control channel search space set. The UE may receive the configuration information and identify the time and frequency resources allocated for the PDSCH in the second TTI, and receive the PDSCH transmission in the second TTI.

Abstract: Wireless communications systems and methods related to reusing long-term evolution (LTE) resources in a nested network system are provided. A first wireless communication device receives, from a second wireless communication device, a reference signal configuration of a first network of a long-term evolution (LTE) radio access technology (RAT). The first wireless communication device and the second wireless communication device are associated with a second network of another RAT. The first wireless communication device receives, from the second wireless communication device, a communication signal in the second network based on the reference signal configuration of the first network. The reference signal configuration indicates at least one of a frequency tone of a reference signal of the first network, a time period of the reference signal of the first network, or a number of antenna ports associated with the reference signal of the first network.

Abstract: Methods, systems, and devices for wireless communications provide for transmission of a beam switch command to a user equipment (UE) via control channel signaling. The UE may establish a connection with a base station using a first transmission beam, receive configuration information configuring the UE to select between a first decoding hypothesis corresponding to downlink control information (DCI) including a bit field including a beam switch command and a second decoding hypothesis corresponding to the DCI not including the bit field, receive a downlink control channel transmission via the first transmission beam, decode the downlink control channel transmission in accordance with the configuration information to obtain decoded DCI, and communicate with the base station based at least in part on the decoded DCI.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may communicate with a user equipment (UE) using multiple antennas. Data streams may be mapped to the antennas using antenna ports. In some cases, a base station may transmit a transmission configuration indication (TCI) to a UE to indicate quasi co-location (QCL) relationships between antenna ports used for downlink communication with a UE. The UE may use these QCL relationships to identify appropriate techniques for decoding a downlink transmission from the base station. In some cases, it may be appropriate for a base station to update one or more TCI states configured for indicating, to a UE, QCL relationships between antenna ports used for downlink communication with the UE. As described herein, a base station may support techniques for dynamically updating such TCI states (e.g., via downlink control information (DCI) signaling).

Abstract: Described in this disclosure are embodiments for controlling a load and an energy source associated with an entity. A system may determine a first energy level, along with variability for the first energy level, associated with the entity for a first period (e.g., prior to a present time). The system may further determine a contextual data, along with variability for the contextual data, associated with the entity for a second period (e.g., after the present time). The first and second energy levels may be received from one or more control devices in communication with the system. The system may determine a second energy level associated with the entity for the second period. The second energy level may be based at least partly on the first energy level and the contextual data. The system may control, based at least partly on the second energy level, the load and the energy source.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may measure a first reference signal, associated with a frequency band of a long term evolution (LTE) system, and a second reference signal associated with a frequency band of a new radio (NR) system. The frequency band of the NR system may overlap the frequency band of the LTE system. The UE may determine first channel state feedback, associated with the frequency band of the LTE system, and second channel state feedback, associated with the frequency band of the NR system, based at least in part on the first reference signal and the second reference signal, respectively. The UE may report the first channel state feedback or the second channel state feedback in uplink control information (UCI). Other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. Uplink random access channel (RACH) transmissions may be sent on multiple beams by a user equipment (UE). For example, a UE may transmit a random access preamble to a base station in a first RACH transmission, and the base station may respond with a random access response in a second RACH transmission. The second RACH transmission may include an indication for the UE to use multiple transmit beams for a third RACH transmission. Using the indication received from the base station, the UE may proceed to use the indicated two or more beams when sending the third RACH transmission to the base station. Upon receiving the third RACH transmission from the UE, the base station may respond with a fourth RACH transmission, which may further include an indication to the UE to transmit an acknowledgment using one or more beams.
