Description

Systems and methods for indicating phase tracking reference signal-demodulation reference signal association The present disclosure relates to wireless communication, including but not limited to systems and methods for indicating phase tracking reference signal-demodulation reference signal (PTRS-DMRS) associations in general. The standardization organization Third Generation Partnership Project (3GPP) is currently in the process of defining not only 5G New Radio (5G NR) but also a New Radio interface called the Next Generation Packet Core Network (NG-CN or NGC). 5G NR will have the following three main components: the 5G Access Network (5G-AN), the 5G Core Network (5GC), and User Equipment (UE). To facilitate the enabling of different data services and requirements, the elements of 5GC, also known as network functions, have been simplified so that some are software-based and others are hardware-based, and thus they can be adapted as needed. The exemplary embodiments disclosed herein relate to solving one or more of the problems raised in the prior art, as well as providing additional features that will become readily apparent by referring to the following detailed description when taken together with the accompanying drawings. According to various embodiments, exemplary systems, methods, devices, and computer program products are disclosed herein. However, it is understood that these embodiments are presented as examples rather than being limiting, and it will be apparent to those skilled in the art reading this disclosure that various modifications to the disclosed embodiments may be made while remaining within the scope of this disclosure. At least one aspect relates to a system, method, device, or computer-readable medium. A wireless communication device may receive a scheduling grant from a wireless communication node to trigger a first physical uplink shared channel (PUSCH) transmission opportunity group and a second PUSCH transmission opportunity group. The scheduling information returned by the scheduling grant may include at least port association information of PTRS-DMRS. The port association information may include a first port association for the first PUSCH transmission opportunity group and a second port association for the second PUSCH transmission opportunity group. The second port association may be associated with at least a portion of the scheduling information for the first PUSCH transmission opportunity group. In some embodiments, the scheduling grant may include one downlink control information (DCI) or upper-level parameter signaling for one configured grant. In some embodiments, each of the first and second PUSCH transmit opportunity groups may be associated with at least one of a set of sounding reference signal (SRS) resources, SRS resources, spatial relationships, transmit configuration indicator (TCI) status, PUSCH frequency hops, quasi co-location (QCL) information, or a set of power control parameters. In some embodiments, the second port association may be determined according to at least one of an SRS resource indicator (SRI) field, a transmit precoding matrix indicator (TPMI) field, an antenna port field for DMRS, or a PUSCH opportunity number. In some embodiments, the scheduling grant may include downlink control information (DCI). In some embodiments, the PTRS-DMRS association field of the DCI may indicate a first port association and a second port association. In some embodiments, the PTRS-DMRS association field may include a plurality of bits. In some embodiments, a first portion of the plurality of bits may be used to indicate a first port association. In some embodiments, a second portion of the plurality of bits may be used to indicate a second port association. In some embodiments, the number of transmission layers may be two for the first PUSCH transmission opportunity group and two for the second PUSCH transmission opportunity group. In some embodiments, the antenna port field, TPMI field, or SRI field may represent a value identifying a second port association. In certain embodiments, at least one bit of the antenna port indication field may be used to indicate a second port association, and at least one bit may include or be indicated by at least one bit of at least one of the antenna port field, TPMI field, or SRI field. In some embodiments, at least one other bit of the antenna port indication field may be used to indicate scheduled DMRS ports. In some embodiments, at least one other bit of the antenna port indication field may be used to indicate a second port association. In some embodiments, at least one other bit of the TPMI field or SRI field may be used to indicate a scheduling precoding matrix or SRS resource. In some embodiments, at least one other bit of the antenna port indication field may be used to indicate a second port association. In some embodiments, a new field (e.g., a field of x bits) may be defined to indicate a second port association. In
