Methods and apparatuses for transmitting signal
The present disclosure relates to a communication method and system for converging a 5 th -Generation (5G) communication system for supporting higher data rates beyond a 4 th -Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments of the present invention provide a method for transmitting a signal, comprising: selecting a starting position of the signal from a set of candidate starting positions for transmitting the signal; determining a symbol mapping of the signal based on a selected starting position or a set of candidate starting positions of the signal; and transmitting the signal is based on the symbol mapping. The embodiment of the invention also provides a corresponding apparatus.
1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
identifying uplink control information (UCI) associated with a configured grant (CG) based on a first β offset and channel state information (CSI) based on a second β offset; and
transmitting, to a base station, a PUSCH including the UCI associated with the CG and the CSI, wherein the UCI associated with the CG is transmitted on the PUSCH without a hybrid automatic repeat request (HARQ)-acknowledgment (ACK),
wherein the UCI associated with the CG is mapped to a first symbol that does not include a demodulation reference signal (DMRS) after a symbol carrying a DMRS,
wherein the UCI associated with the CG includes at least one of a new data indicator (NDI), a redundancy version (RV), or an HARQ process identifier (ID), and
wherein the first β offset and the second β offset are separately configured.
2. The method according to claim 1 , wherein the CSI is mapped to resources that do not carry the DMRS and the UCI associated with the CG.
3. A method performed by a base station in a wireless communication system, the method comprising:
receiving, from a user equipment (UE), a physical uplink shared channel (PUSCH) including uplink control information (UCI) associated with a configured grant (CG) and channel state information (CSI), wherein the UCI associated with the CG is transmitted on the PUSCH without a hybrid automatic repeat request (HARQ)-acknowledgement (ACK); and
decoding the PUSCH based on the UCI associated with the CG based on a first β offset and the CSI based on a second β offset,
wherein the UCI associated with the CG is mapped to a to a first symbol that does not include a demodulation reference signal (DMRS) after a symbol carrying a DMRS,
wherein the UCI associated with the CG includes at least one of a new data indicator (NDI), a redundancy version (RV), or an HARQ process identifier (ID), and
wherein the first β offset and the second β offset are separately configured.
4. The method according to claim 3 , wherein the CSI is mapped to resources that do not carry the DMRS and the UCI associated with the CG.
5. A user equipment (UE), the UE comprising:
a transceiver; and
a controller configured to:
identify uplink control information (UCI) associated with a configured grant (CG) based on a first β offset, and channel state information (CSI) based on a second β offset, and
transmit, to a base station, a PUSCH including the UCI associated with the CG and the CSI, wherein the UCI associated with the CG is transmitted on the PUSCH without a hybrid automatic repeat request (HARQ)-acknowledgement (ACK),
wherein the UCI associated with the CG is mapped to a first symbol that does not include a demodulation reference signal (DMRS) after a symbol carrying a DMRS,
wherein the UCI associated with the CG includes at least one of a new data indicator (NDI), a redundancy version (RV), or an HARQ process identifier (ID), and
wherein the first β offset and the second β offset are separately configured.
6. The UE according to claim 5 , wherein the CSI is mapped to resources that do not carry the DMRS and the UCI associated with the CG.
7. A base station, the base station comprising:
a transceiver; and
a controller configured to:
receive, from a user equipment (UE), a physical uplink shared channel (PUSCH) including uplink control information (UCI) associated with a configured grant (CG) and channel state information (CSI), wherein the UCI associated with the CG is transmitted on the PUSCH without a hybrid automatic repeat request (HARQ)-acknowledgement (ACK), and
decode the PUSCH based on the UCI associated with the CG based on a first β offset and the CSI based on a second β offset,
wherein the UCI associated with the CG is mapped to a to a first symbol that does not include a demodulation reference signal (DMRS) after a symbol carrying a DMRS,
wherein the UCI associated with the CG includes at least one of a new data indicator (NDI), a redundancy version (RV), or an HARQ process identifier (ID), and
wherein the first β offset second β offset are separately configured.
8. The base station according to claim 7 ,
wherein the CSI is mapped to resources that do not carry the DMRS and the UCI associated with the CG.
