Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a position (e.g., a global navigation satellite system (GNSS)) position of the UE based on a relative position of the UE to another UE. For example, a first UE may determine (e.g., calculate, receive) a relative position of the first UE to a second UE that is selected from a set of UEs including the first UE and the second UE to perform a position acquisition procedure to determine a position of the second UE. The first UE may determine (e.g., calculate, receive) its position based on the relative position of the first UE to the second UE and the position of the second UE and may reset a timer that indicates for the first UE to perform a position acquisition procedure upon expiration of the timer.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. Aspects described herein provide techniques and apparatuses associated with synchronizing a preconfigured uplink resource (PUR) release counter between a base station and a user equipment (UE). For example, the synchronization may be performed in connection with the UE entering a connected mode, the base station reconfiguring a PUR, and/or the like. By synchronizing the PUR release counter, misalignment of the PUR release counter between the UE and the base station may be reduced or eliminated. Reducing the misalignment of the PUR release counter reduces the occurrence of a premature release of a PUR, thus reducing UE interference and improving the likelihood of success of the UE's transmission.

Abstract: A method for wireless communication is presented. The method includes receiving pre-configured uplink resource (PUR) configuration information including one or more least significant bits (LSBs) of a hyper system frame number (H-SFN). The method also includes determining a PUR start time based on the H-SFN identified by the one or more LSBs. The method further includes transmitting data to a base station on a PUR identified in the PUR configuration information at the PUR start time.

Abstract: Methods, systems, and devices for wireless communications are described that support techniques for wireless communications using preconfigured uplink resources. Generally, the described techniques provide for enhancement of communication features including frequency hopping, an uplink control channel, coverage enhancement, timing advance, uplink power control, reconfiguration, a downlink control channel, a downlink data channel, retransmissions, or subcarrier spacing for a UE in idle mode. The UE may receive an uplink resource configuration for uplink communications in idle mode, the uplink resource configuration comprising an indicator associated with allocated resources for the uplink communications in idle mode and a set of parameters. The UE may transmit, while in idle mode, a first uplink transmission associated with a transport block on the allocated resources and according to one or more of the parameters, and monitor for a response to the first uplink transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain, via broadcast signaling or UE-specific signaling, an indication of an uplink communications configuration for one or more uplink wireless communications that span a set of one or more transmission time intervals (TTIs). The indication may be based on one or more types of the one or more uplink wireless communications. The UE may determine a duration of time for which an uplink pre-compensation is to be applied to the one or more uplink wireless communications. The duration of time may be based on one or more parameters of the uplink communications configuration. The UE may output the one or more uplink wireless communications within the duration of time with the uplink pre-compensation applied.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may apply a scaling factor to a transport block of a first size, where the scaling factor may increase the transport block from the first size to a second size. The base station may interleave a set of parts of the transport block of the second size across a set of transmission time intervals (TTIs) in accordance with a transport block allocation pattern, where the set of TTIs may be contiguous or separated from each other by one or more intervening intervals. The base station may transmit, to a user equipment, an indication of the transport block allocation pattern applied to the transport block of the second size, and may transmit the set of parts of the transport block of the second size across the set of TTIs in accordance with the transport block allocation pattern.

Abstract: Methods, systems, and devices for wireless communication are described to indicate a transmission scheme configuration for a message and whether the message is a retransmission or new transmission. In a first example, a base station may configure a subset of one or more feedback process identifiers (IDs) for multicast messages. In such cases, if a grant includes a feedback process ID associated with one of the reserved IDs, the message scheduled by the grant may be a retransmission of a multicast message. In a second example, feedback process IDs may be dynamically allocated to multicast or unicast messages via a corresponding grant. A message may be identified as a new transmission or retransmission of a unicast message or multicast message based on a combination of an ID associated with the grant and a new data indicator (NDI) of the grant.

Abstract: Methods, systems, and devices for wireless communications are described to enable a base station to configure additional reference signals, which may be referred to as configured reference signals, to include in a transmission to a user equipment (UE). The UE may transmit a report to the base station, indicating a UE capability for supporting configured reference signals, and the base station may configure a pattern for the configured reference signals. The base station may transmit an indication of the pattern to the UE, where the indication may include one or more characteristics associated with the configured reference signals. The base station may transmit the configured reference signals to the UE according to the pattern, along with one or more baseline reference signals, within an associated transmission. The UE may use the configured reference signals and the baseline reference signals to receive a transmission from the base station.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may transmit, to a base station of a non-terrestrial network, a random access request message associated with a random access procedure using a transport block size (TBS) and a power control specified for the random access request message (e.g., a payload of the random access request message) for the random access procedure. The random access request message including a random access preamble and a random access payload carrying a buffer status report (BSR) or uplink data, or both. The UE may then monitor a response window based at least in part on transmitting the random access request message. The UE may receive, from the base station of the non-terrestrial network, a response message of the random access procedure during the response window.
