Abstract: Methods, systems, and devices for wireless communication are described that support discontinuous scheduling. A base station may transmit, to a user equipment (UE), a grant of resources of a communication channel over a multiple of aggregated TTIs. The UE may monitor a control channel for the grant of resources transmitted by base station. The base station and the UE may identify a location of an excluded TTI within the plurality of aggregated TTIs. The excluded TTI may correspond to a TTI for communicating synchronization signals, random access channel (RACH) signals, or the like. The base station may communicate with the UE via the resources of the communication channel over at least a subset of the aggregated TTIs based on the grant and the location of the excluded TTI.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may select a waveform configuration and a resource for a user equipment (UE) to use to transmit a random access channel (RACH) message 3 (msg3). The base station may transmit a value indicative of the waveform configuration to the UE, wherein the waveform configuration is further indicative of the selected resource. The UE may receive the value indication and identify the waveform configuration. Based on the waveform configuration, the UE may identify the resource to use to transmit the RACH msg3. The UE may transmit the RACH msg3 using the resource and according to the waveform configuration.

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 communication timing (e.g., random access channel (RACH) timing) in a wireless communication are described. A base station and a user equipment (UE) may perform a communication procedure (e.g., to establish a communication link between the base station the UE). The communication timing associated with the communication procedure may depend on the numerology used for the communication procedure and may be conveyed by the base station to the UE in a control message or via system information. In some cases, the numerology may indicate the communication timing.

Abstract: Methods, systems, and devices for random access channel (RACH) timing in a wireless communication are described. A base station and a user equipment (UE) may perform a RACH procedure to establish a communication link between the base station the UE. The RACH timing associated with the RACH procedure may depend on the numerology used for the RACH procedure and may be conveyed by the base station to the UE in a control message or via system information. In some cases, the numerology may indicate the RACH timing, which may be used to determine a number of symbols or absolute time to be used for portions of the RACH procedure.

Abstract: Aspects are described for modifying transmission of control channel signaling during wireless communication. The described aspects include detecting a communication condition corresponding to signaling information transmitted on a Dedicated Channel (DCH); determining whether a Dedicated Physical Data Channel (DPDCH) is transmitted based on detecting the communication condition; and performing a Dedicated Physical Control Channel (DPCCH) gating pattern in response to the determination that the DPDCH is not transmitted, wherein performing the DPCCH gating pattern includes intermittently transmitting the DPCCH when one or more signaling radio bearers (SRBs) are not being transmitted.

Abstract: A method of wireless communication may include transmitting an uplink slot with a first control region, a second control region, and (e.g., optionally) a data region. Each region may include time resources and frequency resources. Transmitting the uplink slot may include transmitting the first control region in an earlier part of the uplink slot and transmitting the second control region (e.g., and the data region) in a later part of the uplink slot. The first control region may include time-critical control information and the second control region may include non-time-critical control information. A receiver receiving the uplink slot may receive the first control region before receiving the data region and the second control region.
