Uplink transmissions in wireless communications

A method for wireless communication, comprising:

• transmitting, from a base station to a user device, a first message that includes a first set of information for configuring a transmission from the user device to the base station, the first message including at least one field indicating an association between the first message and a second message for configuring the transmission;
• transmitting, from the base station to the user device, the second message including a second set of information for configuring the transmission;
• and
• performing the transmission with the user device based on the first and the second set of information,
• wherein a time-domain position of a second search space of the second message is determined based on an offset between a first search space of the first message and the second search space of the second message;
• or
• wherein the at least one field of the first message indicates whether the user device is to monitor the second message on a downlink control channel, and wherein the at least one field further indicates an aggregation level or a physical downlink control channel candidate of the second message.

A wireless communication apparatus comprising a processor and a memory storing instructions, execution of which by the processor causes the apparatus to:

• receive from a base station, a first message that includes a first set of information for configuring a transmission from the apparatus to the base station, the first message including at least one field indicating an association between the first message and a second message for configuring the transmission;
• receive the second message from the base station, the second message including a second set of information for configuring the transmission;
• and
• perform the transmission based on the first and the second set of information;
• wherein a time-domain position of a second search space of the second message is determined based on an offset between a first search space of the first message and the second search space of the second message;
• or
• wherein the at least one field of the first message indicates whether the apparatus is to monitor the second message on a downlink control channel, and wherein the at least one field further indicates an aggregation level or a physical downlink control channel candidate of the second message.
