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 base station 105-a may perform a communication procedure (e.g., an RRC procedure, such as a cell acquisition procedure, random access procedure, RRC connection procedure, RRC configuration procedure) with the UE 115-a. The base station 105-a may be configured with multiple antennas, which may be used for directional or beamformed transmissions. As part of the communication procedure, the base station 105-a may establish a bi-directional communication link 205 for communication. Additionally, or alternatively, as part of the communication procedure, the base station 105-a may configure the UE 115-a with an allowable MCS and resource allocation (e.g., time and frequency resources) via higher-layer signaling or RRC signaling. In some cases, the UE 115-a may provide a UE capability to the base station 105-a, such that the base station 105-a may configure the UE 115-a based on the UE capability. For example, a UE capability may indicate that the UE 115-a supports standing 16 QAM, 64 QAM, 256 QAM, or 1024 QAM, or a combination thereof. The base station 105-a, as part of the communication procedure, may provide an allowable MCS table, or an indication of an allowable MCS table, for a corresponding logical channel of the UE 115-a.
