SUMMARY OF PARTICULAR EMBODIMENTS

This document discloses methods, systems, and devices related to digital wireless communications, and more specifically, to techniques related to the configuration of multiple transmissions to reduce signaling overhead between a wireless network via a wireless communication node on the wireless network side (e.g., a base station) and a user mobile device or user equipment (UE).

In one exemplary aspect, the disclosed technology can be implemented as a method for wireless communication. The method includes receiving, at a mobile device, a first message from a wireless communication node, the first message including one or more parameters for configuring transmissions between the wireless communication node and the mobile device; performing, based on the one or more parameters included in the first message, a first transmission with the wireless communication node; and performing, based on at least one parameter of the one or more parameters included in the first message, a second transmission with the wireless communication node.

In some embodiments, performing the second transmission is further based on one or more parameters included in a second message from the wireless communication node. In some implementations, the second message is broadcasted or multi-casted by the wireless communication node.

In some embodiments, the one or more parameters in the first message indicate at least one of the following: a time-frequency resource for the first transmission, a time-frequency resource pool for the first transmission, a signal signature specific to the wireless device for the first transmission, a signal signature pool specific to the wireless device for the first transmission, a modulation and coding scheme for the first transmission, a modulation and coding scheme pool for the first transmission, a code rate of the first transmission, a spreading factor of the first transmission, a power of the first transmission, an expected received power for the first transmission, or a power range for the first transmission. In some implementations, the one or more parameters in the first message include information for a semi-persistent scheduling of the first transmission.

In some embodiments, the at least one parameter of the one or more parameters in the first message indicates at least one of the following: a time-frequency resource for the second transmission, a time-frequency resource pool for the second transmission, a signal signature specific to the wireless device for the second transmission, a signal signature pool specific to the wireless device for the second transmission, a modulation and coding scheme for the second transmission, a modulation and coding scheme pool for the second transmission, a power of the second transmission, an expected received power for the second transmission, or a power range for the second transmission. In some implementations, the second transmission includes a semi-persistent re-transmission. In some implementations, the second transmission includes a grant-free transmission. In some embodiments, the first message includes a radio resource control message.

In another exemplary aspect, the disclosed technology can be implemented to provide a method for wireless communication. The method includes transmitting, from a wireless communication node to a mobile device, a first message including one or more parameters for configuring transmissions between the wireless communication node and the mobile device, wherein the one or more parameters indicate information for a first transmission between the wireless communication node and the mobile device, and at least one parameter of the one or more parameters indicates information for a second transmission between the wireless communication node and the mobile device.

In some embodiments, the method includes transmitting, from the wireless communication node, a second message including one or more parameters indicating information for the second transmission between the wireless communication node and the mobile device. In some implementations, the transmitting of the second message is performed by broadcasting or multi-casting.

In some embodiments, the one or more parameters in the first message indicate at least one of the following: a time-frequency resource for the first transmission, a time-frequency resource pool for the first transmission, a signal signature specific to the wireless device for the first transmission, a signal signature pool specific to the wireless device for the first transmission, a modulation and coding scheme for the first transmission, a modulation and coding scheme pool for the first transmission, a code rate of the first transmission, a spreading factor of the first transmission, a power of the first transmission, an expected received power for the first transmission, or a power range for the first transmission. In some implementations, the one or more parameters in the first message include information for a semi-persistent scheduling of the first transmission.

In some embodiments, the at least one parameter of the one or more parameters in the first message indicates at least one of the following: a time-frequency resource for the second transmission, a time-frequency resource pool for the second transmission, a signal signature specific to the wireless device for the second transmission, a signal signature pool specific to the wireless device for the second transmission, a modulation and coding scheme for the second transmission, a modulation and coding scheme pool for the second transmission, a power of the second transmission, an expected received power for the second transmission, or a power range for the second transmission. In some implementations, the second transmission includes a semi-persistent re-transmission. In some implementations, the second transmission includes a grant-free transmission. In some embodiments, the message includes a radio resource control message.

In another exemplary aspect, the disclosed technology can be implemented to provide a wireless communications apparatus comprising a processor. The processor is configured to implement a method described herein.

In yet another exemplary aspect, the various techniques described herein may be embodied as processor-executable code and stored on a computer-readable program medium.
