Abstract

The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method for improving the coverage of an uplink channel for uplink transmission is provided. The method includes receiving, from a base station, configuration information including resource allocation information for transport block (TB) processing over multiple slots (TBoMS), repetitive transmission configuration information, and frequency hopping information, identifying whether repetitive transmission of the TBoMS is configured, based on the configuration information, determining a frequency hopping pattern between TBoMS repetitive transmissions based on the frequency hopping information and a number of slots for frequency hopping in case that the repetitive transmission of the TBoMS is configured, and performing the repetitive transmission of the TBoMS based on the frequency hopping pattern.

First claim

What is claimed is:

1. A method performed by a terminal in a communication system, the method comprising:
receiving, from a base station, a physical uplink shared channel (PUSCH) configuration including information indicating inter-slot frequency hopping and a number of slots for transport block (TB) processing over multiple slots (TBoMS);
receiving, from the base station, downlink control information (DCI);
identifying a starting resource block (RB) based on the DCI; and
performing PUSCH transmission of the TBoMS based on the starting RB and the number of slots for the TBoMS,
wherein the starting RB is a first starting RB in a slot where └n s μ /N FH ┘ mod 2=0,
wherein the starting RB is a second starting RB in a slot where └n s μ /N FH ┘ mod 2=1,
wherein the second starting RB is identified based on the first starting RB and a frequency offset, and
wherein n s μ is a slot number and N FH indicates a number of slots for the frequency hopping.

2. The method of claim 1 ,
wherein the PUSCH configuration further includes information on the frequency offset.

3. The method of claim 1 ,
wherein the PUSCH configuration further includes a number of repetitions, and
wherein repetition of the PUSCH transmission of the TBoMS is performed based on the number of repetitions.

4. The method of claim 1 , wherein the PUSCH configuration further includes information on the number of slots for the frequency hopping.

5. A method performed by a base station in a communication system, the method comprising:
transmitting, to a terminal, a physical uplink shared channel (PUSCH) configuration including information indicating inter-slot frequency hopping and a number of slots for transport block (TB) processing over multiple slots (TBoMS);
transmitting, to the terminal, downlink control information (DCI); and
performing PUSCH reception of the TBoMS based on a starting resource block (RB) and the number of slots for the TBoMS,
wherein the starting RB is a first starting RB in a slot where └n s μ /n FH ┘ mod 2=0,
wherein the starting RB is a second starting RB in a slot where └n s μ /N FH ┘ mod 2=1,
