Abstract: Methods, systems, and devices related to reducing signaling overhead for uplink transmissions are described. In one representative aspect, a method for wireless communication includes transmitting, from the wireless communication node, a first message to a mobile device. The first message identifies one or more resource groups that correspond to a transmission rank to be used by the mobile device for a data transmission from the mobile device to the wireless communication node. The one or more resource groups are selected from a set of candidate resource groups or a set of candidate resources. The method also includes receiving, at the wireless communication node, the data transmission having the transmission rank from the mobile device.

Abstract: A transmitting and receiving point (TRP) divides data scheduled by one downlink control information (DCI) into N data parts, and transmits the N data parts to a receiving side, where N≥1. A value of N and whether the N data parts have a correlation in a case of N>1 are determined by at least one of following scheduling information: a transmission configuration indicator (TCI) field, a demodulation reference signal (DMRS) port indicator, a modulation and coding scheme (MCS), a redundancy version (RV) or a new data indicator (NDI). After receiving the N data parts sent by the TRP, the receiving side determines whether the N data parts have the correlation according to at least one of the TCI, the DMRS port indicator, the MCS, the RV, or the NDI.
