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.

說明書

Some examples of the method, apparatuses, and non-transitory computer-readable medium described herein may further include operations, features, means, or instructions for identifying the allowable MCSs for each logical channel of the set of logical channels based on an indication in a field of a logical channel configuration information element (IE) in the LCP configuration.

Some examples of the method, apparatuses, and non-transitory computer-readable medium described herein may further include operations, features, means, or instructions for identifying the MCS associated with the received uplink grant based on at least one transmission parameter associated with the received uplink grant and comparing the MCS associated with the received uplink grant with the allowable MCSs indicated in the LCP configuration for the corresponding logical channel based on identifying the MCS using the at least one transmission parameter.

Some examples of the method, apparatuses, and non-transitory computer-readable medium described herein may further include operations, features, means, or instructions for determining a set of allowed subcarrier spacing index values in a field of the LCP configuration for the corresponding logical channel of the set of logical channels, identifying that the set of allowed subcarrier spacing index values in the field of the LCP configuration for the corresponding logical channel includes a subcarrier spacing index associated with the received uplink grant and determining whether to use the corresponding logical channel for the received uplink grant based on determining that the set of allowed subcarrier spacing index values in the field of the LCP configuration include the subcarrier spacing index associated with the received uplink grant, where transmitting the data using the corresponding logical channel may be further based on the determining.
