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

Embodiment 14: A method for wireless communications, comprising: generating a logical channel prioritization (LCP) configuration for each logical channel of a set of logical channels associated with a user equipment (UE), the LCP configuration indicating allowable modulation coding schemes (MCSs) for each logical channel of the set of logical channels; transmitting the LCP configuration to the UE during a connection procedure with the UE; and transmitting to the UE an uplink grant for transmitting data using a corresponding logical channel of the set of logical channels, the uplink grant indicating an MCS and information associated with one or more transmission parameters of the uplink grant.

Embodiment 15: The method of embodiment 14, further comprising: scrambling a CRC, in a DCI, with a RNTI and a C-RNTI, wherein transmitting the uplink grant is further based at least in part on the scrambling.

Embodiment 16: The method of any of embodiments 14 or 15, further comprising: selecting one or more PDCCH candidates for transmitting the uplink grant, wherein the PDCCH candidates are associated with a UE-specific search space or a common search space, wherein transmitting the uplink grant is further based at least in part on using the PDCCH candidates.

Embodiment 17: The method of any of embodiments 14 to 16, wherein the connection procedure comprises an RRC procedure.

Embodiment 18: An apparatus comprising at least one means for performing a method of any of embodiments 14 to 17.

Embodiment 19: An apparatus for wireless communications comprising a processor; memory coupled with the processor; and instructions stored in the memory and executable by the processor to cause the apparatus to perform a method of any of embodiments 14 to 17.
