Abstract

Method, systems and devices for data transmission in a cell having large transmission delay. In particular embodiments, assisting information may be sent from a network device to a communication device. The assisting information may be used to calculate a timing offset to determine a correct transmission time to compensate for propagation delay in large cell with significant propagation delay.

Claims (18)

1 . A method comprising:

receiving, in a first message, a scheduling information by a communication device over a radio channel from a network device, the scheduling information including a resource allocation index for determining an initial time interval;

receiving, a system information including assisting information including a configurable offset value; and

transmitting, by the communication device, a scheduled transmission at a final time interval determined based on the initial time interval and the configurable offset value included in the assisting information.

2 . A method comprising:

communicating, in a first message, a scheduling information from a network device in a communication network to a communication device over a radio channel, the scheduling information including a resource allocation index for determining an initial time interval by the communication device;

communicating, a system information including assisting information including a configurable offset value; and

receiving a scheduled transmission at a final time interval determined based on the initial time interval and the configurable offset value included in the assisting information.

3 . A wireless communications apparatus comprising a processor and a memory, wherein the processor is configured to read code from the memory and implement a method recited in claim 1 .

4 . A computer program product comprising a computer-readable program medium code stored thereupon, the code, when executed by a processor, causing the processor to implement a method recited in claim 1 .

5 . A wireless communications apparatus comprising a processor and a memory, wherein the processor is configured to read code from the memory and implement a method recited in claim 2 .

6 . A computer program product comprising a computer-readable program medium code stored thereupon, the code, when executed by a processor, causing the processor to implement a method recited in claim 2 .

7 . The method of claim 1 , wherein:

the scheduling information comprises one of the following: downlink control information (DCI), a configured grant, or uplink grant information carried in random access response.

8 . The method of claim 2 , wherein:

the scheduling information comprises one of the following: downlink control information (DCI), a configured grant, or uplink grant information carried in random access response.

9 . The method of claim 1 , wherein the configurable offset is evaluated based on a maximum round trip delay (RTD) within a cell or within a beam footprint size.

10 . The method of claim 2 , wherein the configurable offset is evaluated based on a maximum round trip delay (RTD) within a cell or within a beam footprint size.
