Abstract: Aspects of the present disclosure provide techniques for uplink (UL) data channel design. An example method is provided for operations which may be performed by a first apparatus. The example method generally comprises determining a number of pilot symbols to transmit for one or more slots of a first subframe based, at least in part, on a coverage enhancement (CE) level, and transmitting at least one uplink data channel having the determined number of pilot symbols in the one or more slots of the first subframe.

Abstract: Methods, systems, and devices for wireless communications are described in which UEs may communicate with satellites or base stations, or both in a non-terrestrial network. Due to large distances between transmitting devices and receiving devices in a non-terrestrial network, the UE may account for propagation delay and frequency shift of communications with a satellite based on location information of the satellite. The UE may receive first satellite location information from a base station or a satellite, via a broadcast message. The UE may receive second satellite location information from the wireless network node via a unicast message, where both the first satellite location information and the second satellite location information relate to a same satellite. The UE may transmit an uplink communication via the satellite based on at least one of the first satellite location information or the second satellite location information.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for pilot design for Narrow-Band Internet of Things (NB-IoT). In certain aspects, the method generally includes determining at least one binary code sequence to use as a demodulation reference signal (DMRS) for a channel transmitted across one or more subframes using one or more tones within a resource block (RB) allocated to the UE for narrowband communication, and transmitting the channel including the DMRS using the one or more tones and the determined binary code sequence. In certain aspects, the binary code sequence may be determined based on a binary random sequence, such as pseudo noise (PN) or Gold sequence.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine a terrestrial characteristic of a cell associated with the base station. A UE may perform a synchronization procedure with the cell and may receive, as part of the synchronization procedure, broadcast signaling associated with the cell. The broadcast signaling may identify the terrestrial characteristic of the cell. The base station may initiate communications with the UE based on the broadcast signaling including the indication of the terrestrial characteristic of the cell.

Abstract: Aspects are provided for dynamic resource sharing between V2V and I2V communications. A wireless device selects resources from a shared resource pool in frequency and time. The shared resource pool is shared for I2V communication and communication over a PC5 interface originating from a User Equipment (UE). The wireless device identifies a first priority level for communication from a set of priority levels for I2V communication and UE originated communication. The set of priority levels may comprise at least one priority level unique to the I2V communication.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for establishing rules for scheduling downlink data transmissions and flow control feedback for the downlink data transmissions to avoid confusion at a base station and a user equipment (UE). In one example, when flow control feedback from a UE is disabled for a downlink data transmission, the UE may still operate according to a timing for reporting flow control feedback for the downlink data transmission. In this example, the UE may drop (e.g., refrain from decoding) other downlink data transmissions based on the timing for reporting flow control feedback. In another example, when flow control feedback from a UE is disabled for a downlink data transmission, other downlink data transmissions to the UE may be scheduled according to one or more rules to avoid confusion.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information indicating whether hybrid automatic repeat request (HARQ) feedback is disabled for one or more HARQ processes. The UE may receive a downlink communication. The downlink communication may include a HARQ process identifier that indicates a HARQ process to be used for the downlink communication. The UE may selectively provide HARQ feedback for the downlink communication based at least in part on the HARQ identifier and information indicating whether HARQ feedback is disabled for the HARQ process. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive an indication of a first set of resources for feedback and an indication of a second set of resources for feedback, where the second set of resources are associated with a smaller quantity of cyclic shifts than the first set of resources. Accordingly, the mobile station may transmit feedback on either the first set of resources or the second set of resources based at least in part on a distance associated with the feedback. As an alternative, the mobile station may compute a timing advance associated with transmission of feedback. Accordingly, the mobile station may feedback that is shifted in time according to the timing advance. Numerous other aspects are described.

Abstract: In an aspect, a satellite-based non-terrestrial network configures multiple preconfigured uplink resources (PURs) for a user equipment (UE). The PURs may be configured one PUR per beam, one PUR per cell, or one PUR for multiple cells. A serving cell of the UE and one or more cells adjacent to the serving cell may each have an associated PUR. The UE selects one of the multiple PURs and sends a transmission using the selected PUR without the UE have a connection to the network. The network sends an ACK in response to the transmission. Either the UE or the network can specify that the UE is to transmit using a first PUR and receive the ACK on a second PUR. The UE can specify when and which PUR to use in the transmission and the network can specify when and which PUR to use in the ACK.
