Abstract
Methods and apparatuses for a joint transmission in a distributed MIMO in wireless communication systems. The methods of BS comprise: identifying a type of UEs comprising a JT UE and a non-joint traffic non-JT UE; receiving, from the JT UE, feedback information for determining an SINR offset; identifying RBs for a C-JT, the RBs being designated for non-JT traffic and comprising at least one of a time domain resource or a frequency domain resource; determining whether to transmit the non-JT traffic on the RBs; determining the SINR offset for the non-JT UE based on a determination whether to transmit the non-JT traffic on the RBs; and performing an interference mitigation operation between JT UEs and non-JT UEs.
Claims20
A base station (BS) in a wireless communication system, the BS comprising:
- a processor configured to identify a type of user equipments (UEs) comprising a joint traffic (JT) UE and a non-joint traffic (non-JT) UE;
- and
- a transceiver operably coupled to the processor, the transceiver configured to receive, from the JT UE, feedback information for determining a signal-to-interference noise ratio (SINR) offset,
- wherein the processor is further configured to:
- identify resource blocks (RBs) for a coherent joint transmission (C-JT), the RBs being designated for non-JT traffic and comprising at least one of a time domain resource or a frequency domain resource,
- determine whether to transmit the non-JT traffic on the RBs,
- determine the SINR offset for the non-JT UE based on a determination whether to transmit the non-JT traffic on the RBs, and
- perform an interference mitigation operation between JT UEs and non-JT UEs.
A method of a base station (BS) in a wireless communication system, the method comprising:
- identifying a type of user equipments (UEs) comprising a joint traffic (JT) UE and a non-joint traffic (non-JT) UE;
- receiving, from the JT UE, feedback information for determining a signal-to-interference noise ratio (SINR) offset;
- identifying resource blocks (RBs) for a coherent joint transmission (C-JT), the RBs being designated for non-JT traffic and comprising at least one of a time domain resource or a frequency domain resource;
- determining whether to transmit the non-JT traffic on the RBs;
- determining the SINR offset for the non-JT UE based on a determination whether to transmit the non-JT traffic on the RBs;
- and
- performing an interference mitigation operation between JT UEs and non-JT UEs.
A non-transitory computer-readable medium comprising program code, that when executed by at least one processor, causes an electronic device to:
- identify a type of user equipments (UEs) comprising a joint traffic (JT) UE and a non-joint traffic (non-JT) UE;
- receive, from the JT UE, feedback information for determining a signal-to-interference noise ratio (SINR) offset;
- identify resource blocks (RBs) for a coherent joint transmission (C-JT), the RBs being designated for non-JT traffic and comprising at least one of a time domain resource or a frequency domain resource;
- determine whether to transmit the non-JT traffic on the RBs;
- determine the SINR offset for the non-JT UE based on a determination whether to transmit the non-JT traffic on the RBs;
- and
- perform an interference mitigation operation between JT UEs and non-JT UEs.
