    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.

    Abstract: Some techniques and apparatuses described herein allocate and/or transmit a narrower bandwidth value for LTE MTC UEs, such as UEs that operate in a small bandwidth mode using LTE procedures, and allocate and/or transmit a wider bandwidth value for 5G MTC UEs, such as UEs that can perform hopping and/or be allocated resources outside of a legacy bandwidth. For example, the wider bandwidth value may be associated with a non-LTE carrier (e.g., a 5G carrier in a 5G bandwidth) with the same center frequency as an LTE carrier associated with the narrower bandwidth value. Some techniques and apparatuses described herein provide for initial access, signaling, paging, random access, unicast communications, frequency hopping, cell-specific reference signaling, narrowband alignment, and/or other coexistence considerations for LTE MTC UEs operating on an LTE carrier and 5G MTC UEs operating on a non-LTE carrier with a bandwidth that includes the LTE carrier.

    Abstract: Methods, systems, and devices for wireless device are described. A wireless device may receive a configuration for a data radio bearer associated with voice traffic in a wireless communications network. In some examples, the configuration may indicate one or more parameters associated with the voice traffic. Additionally, or alternatively, the wireless device may receive a configuration for a data radio bearer and a configured grant associated with voice traffic. The wireless device may identify a mapping between a configured grant identifier and the data radio bearer based on the configuration In some examples, the wireless device may generate a transport block including the voice traffic based on the one or more parameters associated with the voice traffic or the mapping between the configured grant identifier and the data radio bearer. The wireless device may then transmit the generated transport block including the voice traffic.
