Abstract
A method and apparatus for transmitting and receiving signals in a wireless vehicle communication system. The method, performed by a UE, includes obtaining vehicle communication configuration information, determining, for vehicle communication, at least one of whether data is to be relayed, allocated resources, or a waveform, based on the obtained vehicle communication configuration information, and transmitting or receiving signals to or from at least one other UE based on the determination result.
Claims20
A method of transmitting or receiving a signal by a user equipment (UE) in a wireless sidelink communication system, the method comprising:
- receiving sidelink communication configuration information;
- receiving sidelink control information (SCI) associated with a long term evolution (LTE) network;
- based on the sidelink communication configuration information, identifying whether a first sidelink signal using the LTE network and a second sidelink signal using a new radio (NR) network overlap in time;
- in response to identifying that the first sidelink signal using the LTE network and the second sidelink signal using the NR network overlap in time, identifying whether a priority of the first sidelink signal is higher than a priority of the second sidelink signal based on a priority field included in the SCI;
- and
- transmitting, to at least one other UE, a signal with a higher priority among the first sidelink signal or the second sidelink signal,
- wherein a sidelink resource includes resource regions except resource regions previously configured for synchronization signal (SS) or physical broadcast channel (PBCH).
The method of claim I. further comprising:
- determining resources for first-type sidelink communication in a time-frequency resource region, based on resource information for the first-type sidelink communication, the resource information being received from the sidelink communication configuration information;
- and
- determining resources remaining after the resources for the first-type sidelink communication in the time-frequency resource region are excluded, as resources for second-type sidelink communication.
A user equipment (UE) for transmitting and receiving signals in a wireless sidelink communication system, the UE comprising:
- a transceiver;
- and
- at least one processor connected with the transceiver and configured to:
- receive sidelink communication configuration information,
- receive sidelink control information (SCI) associated with a long term evolution (LTE) network,
- based on the sidelink communication configuration information, identify whether a first sidelink signal using the LTE network and a second sidelink signal using a new radio (NR) network overlap in time,
- in response to identifying that the first sidelink signal using the LTE network and the second sidelink signal using the NR network overlap in time, identify whether a priority of the first sidelink signal is higher than a priority of the second sidelink signal based on a priority field included in the SCI, and
- transmit or receive, to or from at least one other UE, a signal with a higher priority among the first sidelink signal or the second sidelink signal,
- wherein a sidelink resource includes resource regions except resource regions previously configured for synchronization signal (SS) or physical broadcast channel (PBCH).
The UE of claim II, wherein the processor is further configured to determine whether data is to be relayed, and to determine whether a waveform to be used is the same at the at least one other UE, based on the received sidelink communication configuration information, and
- wherein the sidelink communication configuration information is included in at least one of a media access control (MAC) control element (CE), radio resource control (RRC) configuration information, or downlink (DL) control information, and
- wherein the processor is further configured to determine whether the UE is to relay received data to the at least one other UE, based on the sidelink communication configuration information.
