Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit procedure-specific uplink power parameters to one or more user equipments (UEs) in a cell. A UE may determine a procedure including one or more uplink transmissions. The UE may determine a transmit power level corresponding to the procedure based at least in part on the procedure-specific uplink power parameters. The UE may transmit the one or more uplink transmissions using the determined transmit power level.

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.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems may support beamformed transmissions between devices (e.g., to improve coverage range). The beamformed transmissions may depend on discovery and maintenance of receive and transmit beams over which a given device may communicate with another device. Various receive and transmit beams for a given device may be compared using reference signals. As the number of devices attempting to access a cell increases, the number of reference signals to be transmitted may scale proportionally. Large numbers of reference signals may flood time-frequency resources of the system and/or require excessive processing at a mobile device. Scrambling sequences for reference signals may be employed to improve efficiency of resource usage. In aspects, the scrambling sequences may be implicitly determined (e.g., based on resources over which the access request was transmitted). Such an implicit association may reduce the need for additional signaling.

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 communication are described. Wireless communications systems may support uplink random access channel (RACH) transmissions on multiple beams and over multiple component carriers (CCs). A wireless device may transmit a random access preamble to a base station in a first RACH transmission, which may indicate a set of CCs over which the base station may respond with a random access response (RAR) in a second RACH transmission. The second RACH transmission may then include an indication for which CCs the wireless device may use for a subsequent RACH transmission (e.g., a RACH message 3). The wireless device may also indicate a beam index and/or time-frequency resources associated with beams and/or CCs used for such cell acquisition transmissions. In other examples, the base station may indicate resources (e.g., via a handover command or RACH command) for wireless device scheduling request and/or beam-failure recovery request transmission.

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: A user equipment apparatus determines whether a transmission is received from a base station within a time window and skips measurement of a reference signal during a subsequent period, when a transmission is received from the base station within the time window. A base station apparatus configures a UE to monitor one or more reference signals associated with a beam pair link and transmits a first signal in a transmission to the UE. The base station determines whether the transmission is received at the UE within a time window and determines whether to transmit a reference signal, based on whether the transmission is received at the UE within the time window. Upon determining that the transmission was received at the UE, the base station may skip transmission of the reference signal or modify a time, a frequency, a power, and/or a reference signal offset for the reference signal.

Abstract: Aspects of the present disclosure relate to techniques for multibeam PDCCH monitoring during CDRX operations. A BS may determine a configuration of one or more beams for a UE to monitor for receiving a downlink control channel from the BS, wherein the configuration is based, at least in part, on a monitoring window since the subframe in which the downlink control channel (e.g., PDCCH), indicates an initial UL, DL, or SL use data transmission for the UE. The BS may transmit, to the UE, an indication of the configuration. A UE may perform corresponding operations and may monitor one or more beams based on the received configuration.

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.
