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

The grant component 615 may receive an uplink grant for transmitting data using a corresponding logical channel of the set of logical channels. In some examples, the grant component 615 may identify cell information associated with the base station based on at least one transmission parameter of the uplink grant.

The MCS component 620 may identify an MCS associated with the received uplink grant. In some examples, the MCS component 620 may identify 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 IE in the LCP configuration. In some examples, the MCS component 620 may identify the MCS associated with the received uplink grant based on at least one transmission parameter associated with the received uplink grant.

The logical channel component 625 may transmit the data using the corresponding logical channel with the identified MCS. In some examples, the logical channel component 625 may refrain from using the corresponding logical channel for the received uplink grant based on the MCS associated with the received uplink grant being different from the allowable MCSs for the corresponding logical channel. In some examples, the logical channel component 625 may identify a second corresponding logical channel from the set of logical channels configured with the MCS associated with the received uplink grant based on comparing the MCS associated with the received uplink grant with the allowable MCSs for the second corresponding logical channel.
