摘要

Methods, systems, and devices for wireless communications are described. A base station in a wireless communications system may perform a connection procedure (e.g. radio resource control (RRC) procedure) with a user equipment (UE), during which the base station may configure the UE with logical channel prioritization (LCP) configuration for each logical channel of a set of logical channels. The LCP configuration may indicate allowable modulation coding schemes (MCSs) for each logical channel of the set of logical channels. Following the communication procedure, the UE may receive an uplink grant for transmitting data using a corresponding logical channel of the set of logical channels. The UE may identify an MCS used by the uplink grant and may transmit the data using the corresponding logical channel with the identified MCS, based on the identified MCS of the uplink grant matching an MCS of the logical channel.

UEs within a wireless communications system may have different requirements based on an application or deployment scenario. Systems may, therefore, be designed to support multiple wireless communications services. For example, a system may support wireless communication services with certain enhanced reliability and latency targets. However, resource configurations and certain transmission restrictions, for example, may limit the system's ability to achieve such targets.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support high-reliability modulation coding scheme (MCS) and logical channel prioritization (LCP) in accordance with various aspects of the present disclosure. Generally, the described techniques provide for transmission of communications data having certain reliability and latency thresholds. For example, a base station and user equipment (UE) may be in communication with each other, and the UE may support the use of low latency services, such as ultra-reliable low latency communications (URLLC). The base station may configure an LCP configuration for each logical channel of a set of logical channels for a UE during a connection procedure with the UE (e.g., radio resource control (RRC) procedure).
