In the following, unless explicitly stated, a resource in both frequency domain and time domain will be used as an example of a transmission resource for describing some example embodiments of the present disclosure. It is noted that example embodiments of the present disclosure are equally applicable to other resources in other domains.
As discussed above, technology of ISAC has been agreed as a feature to be supported in the future communication. Generally speaking, measuring reference signal (RS) is a necessary operation for both sensing and communication. However, the requirements of the measurement report used for sensing and the requirements of measurement report used for communications are different.
Specifically, as for MIMO scenario, the MIMO channel may be decomposed into spatial domain (SD, which may be identified by angle, beam, SD vector and so on) , frequency domain (FD, which may be identified by FD vector or delay information and so on) .
The delay information may be useful for both communication and sensing (at least in case of sensing a target object based on a transmitter and a receiver) . However, absolute delay is not needed for communication (such as, calculating the precoder or channel quality indicator, PMI, CSI) , while it is needed for sensing.
In view of this, in order to achieve ISAC based on MIMO, further enhancements for measuring and reporting the RSs, especially for how to measure/quantize the delay, is needed.
According to the present disclosure, a solution for configuring and transmitting the measurement report to achieve ISAC is proposed. In this solution, the first device (such as, a terminal device) receives configuration information of measurement report from a second device (such as, a network device) . Based on the first configuration information, the first device transmits at least one measurement report to the second device. The at least one measurement report may indicate at least one of the following: a first set of first information related to SD, a second set of second information related to FD or timing information for path, a third set of amplitude coefficients, a fourth set of phase coefficients, or a fifth set of timing information for a set of rays associated with one second information in the second set of second information.
In particular, the at least one measurement report may comprise a first subset of information and a second subset of information, wherein one of the first and second subsets of information is applied for a calculation/report of precoder or CQI. Alternatively, or in addition, the at least one measurement report may comprise a first measurement report and a second measurement report associated with the first measurement report.
In this way, the at least one measurement report may be used for both sensing and communication (e.g., the calculation/report of precoder or CQI or PMI or CSI) .
It is to be understood that the scenario of ISAC would be especially benefit from the example embodiments of the present disclosure. However, it does not mean that the example embodiments of the present disclosure can be implemented only for this specific scenario. Actually, the example embodiments of the present disclosure may be implemented in any scenario where at least one measurements report is associated with at least two different functionalities. The present disclosure is not limited in this regard.
Further, due to sensing has been agreed as a feature supported in the 5GC system, thus, more network elements, including terminal device, network device (such as, a next generation eNodeB (ng-eNB) , or a gNB in the next generation radio access network (NG-RAN) ) , 5GC function (such as, an access and mobility management function (AMF) , an integrated sensing management function (ISMF) , a sensing function (SF) or a location management function (LMF) ) and other third-party entity (such as, a sensing service requester) , are involved in the sensing measurement. In view of this, how to communicate signalling (s) /message (s) among these network elements are also desirable to be further discussed.
According to the present disclosure, a solution for configuring and transmitting channel information is proposed. In this solution. The first node receives at least one first message for sensing from a second node or a function entity. Then, the first node transmits at least one second message to at least one of the second node or the function entity, where the at least one second message comprises information used for sensing and the at least one second message is determined by the first node by measuring a first set of RSs transmitted by the second node. Alternatively, the first node transmits a second set of RSs to the second node, such that the second node may generate at least one third message comprising information used for sensing.
In summary, by communicating the first message, the second message and/or the third message, the first/second node may obtain the sensing signals and sensing measurements. As a result, sensing feature may be well supported in the 5GC network.
As used herein, the terms “UE expects” , “UE does not expect, “terminal device expects” , “terminal device does not expect” may imply restrictions on a configuration of a network device (also referred to as NW configuration) . The terms “UE is not expected to” and “terminal device is not expected to” may imply a terminal implementation, also referred to as UE implementation. In some embodiments, the terms “UE does not expect” and “UE is not expected to” may be used equally.
