Description

SYSTEMS AND METHODS FOR MEASUREMENT AND REPORT

TECHNICAL FIELD

The disclosure relates generally to wireless communications, including but not limited to systems and methods for (e.g., layer 1 or on-demand based) measurement and report.

BACKGROUND

The standardization organization Third Generation Partnership Project (3GPP) is currently in the process of specifying a new Radio Interface called 5G New Radio (5G NR) as well as a Next Generation Packet Core Network (NG-CN or NGC) . The 5G NR will have three main components: a 5G Access Network (5G-AN) , a 5G Core Network (5GC) , and a User Equipment (UE) . In order to facilitate the enablement of different data services and requirements, the elements of the 5GC, also called Network Functions, have been simplified with some of them being software based, and some being hardware based, so that they could be adapted according to need. Communication via satellite is one of the typical scenarios of the non-terrestrial networks in 3GPP standardization.

SUMMARY

The example embodiments disclosed herein are directed to solving the issues relating to one or more of the problems presented in the prior art, as well as providing additional features that will become readily apparent by reference to the following detailed description when taken in conjunction with the accompany drawings. In accordance with various embodiments, example systems, methods, devices and computer program products are disclosed herein. It is understood, however, that these embodiments are presented by way of example and are not limiting, and it will be apparent to those of ordinary skill in the art who read the present disclosure that various modifications to the disclosed embodiments can be made while remaining within the scope of this disclosure.

At least one aspect is directed to a system, method, apparatus, or a computer-readable medium of the following. A wireless communication device (e.g., a user equipment (UE) ) may receive an on-demand (OD) synchronization signal block (SSB) and a channel state information (CSI) report configuration. The wireless communication device may send a CSI report according to the OD SSB and the CSI report configuration. In some embodiments, the wireless communication device may receive at least one of: a first signaling, a periodic SSB, a second signaling, a CSI resource configuration, or a list of one or more trigger states.

In some embodiments, the CSI resource configuration may comprise at least one of: one or more CSI-ResourceConfig, one or more csi-RS resource set lists, one or more nzp-CSI-RS-SSBs, one or more csi-IM resource set lists, one or more nzp-CSI-RS resource set lists, one or more csi-SSB resource set lists, one or more csi-ODSSB resource set lists, one or more NZP-CSI-RS resource sets, one or more CSI-SSB resource sets, one or more CSI-ODSSB resource sets, one or more csi-SSB resource lists, one or more csi-ODSSB resource lists, one or more NZP-CSI-RS resources, one or more SSB-Indexes, or one or more ODSSB-Indexes. In some embodiments, the OD SSB can be quasi co-located (QCLed) with the periodic SSB. The periodic SSB can be used as a reference to determine the Doppler shift, average delay or spatial parameters of the on-demand SSB.

In some embodiments, the CSI report configuration can be associated with at least one of: one or more CSI resource configurations, one or more resources of a SSB, or one or more resources of the OD SSB. According to the configuration, the SSB based or on-demand SSB based measurement and reporting can be implemented. In some embodiments, when the CSI report configuration is associated with the one or more resources of the OD SSB, a report quantity of the CSI report configuration can be set to at least one of: “cri-RSRP” , “cri-SINR” , “ssb-Index-RSRP” , “ssb-Index-SINR” ', “cri-RSRP-Index” , “ssb-Index-RSRP-Index” , “cri-SINR-Index” , “ssb-Index-SINR-Index” , or “none” . Considering the characteristics of the on-demand SSB, some on-demand SSB based measurement results may not meet the expected target. Unreasonable configuration can be improved by limiting the report quality of the on-demand SSB based CSI report.

In some embodiments, each of the one or more trigger states can be associated with one or more CSI report configurations. Each of the one or more trigger states can be associated with one or more OD SSB based CSI report configurations. In some embodiments, the one or more trigger states can be associated with at least one of: one or more entry numbers of one or more nzp-CSI-RS resource sets, one or more entry numbers of one or more csi-SSB resource sets, or one or more entry numbers of one or more csi-ODSSB resource sets. The association relationship described above may ensure that each trigger state can be associated with one or more resource sets. When a trigger state is indicated to take effect /function /operate, the associated resource sets can be taken into effect.

In some embodiments, the first signaling may comprise at least one of: an indication of the OD SSB, an indication of an aperiodic CSI report, or an indication of a semi-persistent (SP) CSI report. According to the first signaling, the on-demand SSB transmission and/or the CSI report based on the on-demand SSB can be indicated. In some embodiments, the OD SSB can be associated with at least one of: a periodic CSI report configuration, a SP CSI report configuration, or an aperiodic CSI report configuration.

In some embodiments, when the wireless communication device receives the first signaling, the CSI report configuration associated with the OD SSB can be initiated. In such way, the on-demand SSB-based CSI report may take effect without additional indication, which can save signaling overhead and reduce latency. In some embodiments, the second signaling may comprise at least one of: an indication of an aperiodic CSI report, or an indication of a semi-persistent (SP) CSI report. In some embodiments, the indication of the aperiodic CSI report can be used to initiate at least one trigger state in the list of the one or more trigger states. In some embodiments, the indication of the SP CSI report can be used to indicate an activation status or a deactivation status of one or more SP CSI report configurations. In some embodiments, each bit of the indication of the SP CSI report may correspond to a SP CSI report configuration or an OD SSB based SP CSI report configuration. The bitmap can effectively indicate the activation/deactivation of one or more SP CSI report configurations, and can reduce bit overheads.

In some embodiments, the csi-RS resource set list may comprise at least one of: a nzp-CSI-RS-SSB, a csi-IM resource set list, or a csi-ODSSB resource set list. A csi-ODSSB resource set list can be added to the csi-RS resource set list. By configuring the on-demand SSB based resource set, the UE can effectively distinguish the legacy SSB based resources from on-demand SSB based resources, reducing fuzzy problems that occur during SSB based measurement and reporting. In some embodiments, the nzp-CSI-RS-SSB may comprise at least one of: a nzp-CSI-RS resource set list, a csi-SSB resource set list, or a csi-ODSSB resource set list. A csi-ODSSB resource set list can be added to the nzp-CSI-RS-SSB. By configuring the on-demand SSB based resource set, the UE can effectively distinguish the legacy SSB based resources from on-demand SSB based resources, reducing fuzzy problems that occur during SSB based measurement and reporting.

In some embodiments, the csi-ODSSB resource set list may comprise at least one of: one or more CSI-ODSSB resource sets, one or more csi-ODSSB resource lists, or one or more csi-ODSSB resources. In some embodiments, the CSI-SSB resource set may comprise at least one of: a csi-SSB resource list, or a csi-ODSSB resource list. The csi-ODSSB resource list can be configured within the CSI-SSB resource set. With the configuration, the UE may be able to keep the resource set of the legacy system unchanged. The on-demand SSB and legacy SSB can be distinguished by the SSB resources associated with the resource set. The ambiguous can be improved according to the configuration. In some embodiments, the csi-ODSSB resource list may comprise one or more ODSSB-Indexes.

In some embodiments, a wireless communication node (e.g., a base station (BS) ) may send an on-demand (OD) synchronization signal block (SSB) and a channel state information (CSI) report configuration to a wireless communication device (e.g., a user equipment (UE) ) . The wireless communication node may receive a CSI report according to the OD SSB and the CSI report configuration from the wireless communication device.

In the following discussion, the wireless communication network 100 may be any wireless network, such as a cellular network or a narrowband Internet of things (NB-IoT) network, and is herein referred to as “network 100. ” Such an example network 100 includes a base station 102 (hereinafter “BS 102” ; also referred to as wireless communication node) and a user equipment device 104 (hereinafter “UE 104” ; also referred to as wireless communication device) that can communicate with each other via a communication link 110 (e.g., a wireless communication channel) , and a cluster of cells 126, 130, 132, 134, 136, 138 and 140 overlaying a geographical area 101. In Figure 1, the BS 102 and UE 104 are contained within a respective geographic boundary of cell 126. Each of the other cells 130, 132, 134, 136, 138 and 140 may include at least one base station operating at its allocated bandwidth to provide adequate radio coverage to its intended users.

For example, the BS 102 may operate at an allocated channel transmission bandwidth to provide adequate coverage to the UE 104. The BS 102 and the UE 104 may communicate via a downlink radio frame 118, and an uplink radio frame 124 respectively. Each radio frame 118/124 may be further divided into sub-frames 120/127 which may include data symbols 122/128. In the present disclosure, the BS 102 and UE 104 are described herein as non-limiting examples of “communication nodes, ” generally, which can practice the methods disclosed herein. Such communication nodes may be capable of wireless and/or wired communications, in accordance with various embodiments of the present solution.

FIG. 2 illustrates a block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM/OFDMA signals) in accordance with some embodiments of the present solution. The system 200 may include components and elements configured to support known or conventional operating features that need not be described in detail herein. In one illustrative embodiment, system 200 can be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment such as the wireless communication environment 100 of Figure 1, as described above.

System 200 generally includes a base station 202 (hereinafter “BS 202” ) and a user equipment device 204 (hereinafter “UE 204” ) . The BS 202 includes a BS (base station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each module being coupled and interconnected with one another as necessary via a data communication bus 220. The UE 204 includes a UE (user equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each module being coupled and interconnected with one another as necessary via a data communication bus 240. The BS 202 communicates with the UE 204 via a communication channel 250, which can be any wireless channel or other medium suitable for transmission of data as described herein.

As would be understood by persons of ordinary skill in the art, system 200 may further include any number of modules other than the modules shown in Figure 2. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in connection with the embodiments disclosed herein may be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps are described generally in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software can depend upon the particular application and design constraints imposed on the overall system. Those familiar with the concepts described herein may implement such functionality in a suitable manner for each particular application, but such implementation decisions should not be interpreted as limiting the scope of the present disclosure

In accordance with some embodiments, the UE transceiver 230 may be referred to herein as an "uplink" transceiver 230 that includes a radio frequency (RF) transmitter and a RF receiver each comprising circuitry that is coupled to the antenna 232. A duplex switch (not shown) may alternatively couple the uplink transmitter or receiver to the uplink antenna in time duplex fashion. Similarly, in accordance with some embodiments, the BS transceiver 210 may be referred to herein as a "downlink" transceiver 210 that includes a RF transmitter and a RF receiver each comprising circuity that is coupled to the antenna 212. A downlink duplex switch may alternatively couple the downlink transmitter or receiver to the downlink antenna 212 in time duplex fashion. The operations of the two transceiver modules 210 and 230 may be coordinated in time such that the uplink receiver circuitry is coupled to the uplink antenna 232 for reception of transmissions over the wireless transmission link 250 at the same time that the downlink transmitter is coupled to the downlink antenna 212. Conversely, the operations of the two transceivers 210 and 230 may be coordinated in time such that the downlink receiver is coupled to the downlink antenna 212 for reception of transmissions over the wireless transmission link 250 at the same time that the uplink transmitter is coupled to the uplink antenna 232. In some embodiments, there is close time synchronization with a minimal guard time between changes in duplex direction.

The UE transceiver 230 and the base station transceiver 210 are configured to communicate via the wireless data communication link 250, and cooperate with a suitably configured RF antenna arrangement 212/232 that can support a particular wireless communication protocol and modulation scheme. In some illustrative embodiments, the UE transceiver 210 and the base station transceiver 210 are configured to support industry standards such as the Long Term Evolution (LTE) and emerging 5G standards, and the like. It is understood, however, that the present disclosure is not necessarily limited in application to a particular standard and associated protocols.

In accordance with various embodiments, the BS 202 may be an evolved node B (eNB) , a serving eNB, a target eNB, a femto station, or a pico station, for example. In some embodiments, the UE 204 may be embodied in various types of user devices such as a mobile phone, a smart phone, a personal digital assistant (PDA) , tablet, laptop computer, wearable computing device, etc. The processor modules 214 and 236 may be implemented, or realized, with a general purpose processor, a content addressable memory, a digital signal processor, an application specific integrated circuit, a field programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein.

The memory modules 216 and 234 may also be integrated into their respective processor modules 210 and 230. In some embodiments, the memory modules 216 and 234 may each include a cache memory for storing temporary variables or other intermediate information during execution of instructions to be executed by processor modules 210 and 230, respectively. Memory modules 216 and 234 may also each include non-volatile memory for storing instructions to be executed by the processor modules 210 and 230, respectively.

The network communication module 218 generally represents the hardware, software, firmware, processing logic, and/or other components of the base station 202 that enable bi-directional communication between base station transceiver 210 and other network components and communication nodes configured to communication with the base station 202. For example, network communication module 218 may be configured to support internet or WiMAX traffic. In a typical deployment, without limitation, network communication module 218 provides an 802.3 Ethernet interface such that base station transceiver 210 can communicate with a conventional Ethernet based computer network. In this manner, the network communication module 218 may include a physical interface for connection to the computer network (e.g., Mobile Switching Center (MSC) ) .

2. Systems and Methods for Measurement and Report

A periodically transmitted synchronization signal /physical broadcast channel (SS /PBCH) may cause a large amount of power consumption by a network. To reduce the power consumption of the network, an on-demand (OD) synchronization signal block (SSB) transmission mode can be performed. With an on-demand SSB transmission mode, the network can achieve energy savings without affecting system performance and user experience. The current protocol only supports the measurement and reporting based on periodic SSBs. Therefore, the current disclosure provides systems and methods to allow/enable measurement and/or reporting based on on-demand or aperiodic SSBs.

In some embodiments, a CSI-ReportConfig can be associated with one or more channel state information reference signal (CSI-RS) resource settings through/by a CSI-resourceConfigID. In some embodiments, in a channel state information (CSI) report configuration, a reportConfigType can be configured. The reportConfigType may indicate a time domain behavior of the CSI report configuration. The time domain behavior can be at least one of: periodic, semiPersistentOnPUCCH, semiPersistentOnPUSCH, or aperiodic. FIG. 3 illustrates an example configuration, in accordance with some embodiments of the present disclosure.

In some embodiments, each CSI resource setting (e.g., CSI-ResourceConfig) may include a configuration of a list of S ≥ 1 CSI resource sets (given by higher layer parameter csi-RS-ResourceSetList) . The list may comprise references to either or both of non-zero-power (NZP) CSI-RS resource set (s) and SS/PBCH block set (s) . In certain embodiments, the list may comprise references to resource for interference measurement (e.g., CSI-IM resource set (s) ) . FIG. 4 illustrates an example configuration, in accordance with some embodiments of the present disclosure.

In some embodiments, for L1-SINR computation and channel measurement, the UE may be configured with NZP CSI-RS resources and/or SS/PBCH Block resources. In some embodiments, for L1-RSRP computation, the UE may be configured with CSI-RS resources, SS/PBCH block resources or both CSI-RS and SS/PBCH block resources, when resource-wise quasi co-located (QCL) with “type C” and “typeD” applicable.

In this disclosure, a secondary cell can be (or replaced by or referenced as) a primary cell, a cell, a serving cell, a carrier, a frequency band, a bandwidth part, and/or a frequency resource element. A primary cell can be (or replaced by or referenced as) a cell, a serving cell, a carrier, a frequency band, a bandwidth part, and/or a frequency resource element. A carrier can be (or replaced by or referenced as) a cell, a serving cell, a frequency band, a bandwidth part, and/or a frequency resource element. A synchronization signal block (SSB) can be (or replaced by or referenced as) a synchronization signal/physical broadcast channel (SS/PBCH) , a secondary synchronization signal, a primary synchronization signal, a synchronization signal, a signal for measurement, a signal for idle/inactive mode UE, and/or a signal for connected mode UE. The system information may comprise at least one of: a master information block (MIB) , a system information block 1 (SIB1) , a number of system information blocks (SIBs) other than SIB1 and SIBs for positioning.

A wireless communication device (e.g., a user equipment (UE) ) may receive an on-demand (OD) synchronization signal block (SSB) and a channel state information (CSI) report configuration. The wireless communication device may send a CSI report according to the OD SSB and the CSI report configuration. In some embodiments, the wireless communication device may receive at least one of: a first signaling, a periodic SSB, a second signaling, a CSI resource configuration, or a list of one or more trigger states. For example, a UE may receive at least one of: a first signaling, an on-demand SSB, a periodic SSB, a second signaling, a channel state information (CSI) report configuration, a CSI resource configuration, or a trigger state list. The UE may perform corresponding operations (e.g., CSI reporting, or measurements) according to the signaling received by the UE. In some embodiments, at least one of: the CSI report configuration, the CSI resource configuration, or the trigger state list can be determined by a medium access control control element (MAC CE) signaling or a radio resource control (RRC) signaling.

In some embodiments, the OD SSB can be quasi co-located (QCLed) with the periodic SSB. The periodic SSB can be used as a reference to determine the Doppler shift, average delay or spatial parameters of the on-demand SSB. In some embodiments, when both the on-demand SSB and the periodic SSB are transmitted on the cell, the on-demand SSB can be quasi co-located (QCLed) with the periodic SSB. For example, the on-demand SSB with index i can be QCLed with the periodic SSB with index i. For another example, the on-demand SSB with index i can be QCLed with the (i+1) -th transmitted periodic SSB.

In some embodiments, the CSI report configuration can be associated with a report type. The report type can be periodic, semi-persistent on PUCCH, semi-persistent on a physical uplink shared channel (PUSCH) , or aperiodic.

In some embodiments, the CSI report configuration can be associated with at least one of:one or more CSI resource configurations, one or more resources of a SSB, or one or more resources of the OD SSB. According to the configuration, the SSB based or on-demand SSB based measurement and reporting can be implemented. The CSI report configuration may be associated with one or more CSI resource configurations.

In some embodiments, the resource of SSB can be replaced by or referenced as SSB resource or SSB-Index. The resource of on-demand SSB can be replaced by or referenced as ODSSB resource or ODSSB-Index.

In some embodiments, the CSI report configuration can be associated with one or more on-demand SSB resources. For example, the CSI resource configuration associated with the CSI report configuration may comprise one or more on-demand SSB resources. In some embodiments, when the CSI report configuration is associated with the one or more resources of the OD SSB, a report quantity of the CSI report configuration can be set to at least one of: “cri-reference signal received power (RSRP) ” , “cri-signal interference noise ratio (SINR) ” , “ssb-Index-RSRP” , “ssb-Index-SINR” ', “cri-RSRP-Index” , “ssb-Index-RSRP-Index” , “cri-SINR-Index” , “ssb-Index-SINR-Index” , or “none” . Considering the characteristics of the on-demand SSB, some on-demand SSB based measurement results may not meet the expected target. Unreasonable configuration can be improved by limiting the report quality of the on-demand SSB based CSI report. In some embodiments, when the report quantity of the a CSI report configuration is set to “cri-RSRP” , “cri-SINR” , “ssb-Index-RSRP” , “ssb-Index-SINR” , “cri-RSRP-Index” , “ssb-Index-RSRP-Index” , “cri-SINR-Index” , “ssb-Index-SINR-Index” or “none” , then the CSI report configuration can be associated with the on-demand SSB resources. In some embodiments, when the CSI report configuration is associated with the on-demand SSB resources, the report type may not be configured as periodic. In some other embodiments, when the CSI report configuration is associated with the on-demand SSB resources, the report type may not be configured as aperiodic.

In some embodiments, when the CSI report configuration is associated with the on-demand SSB resources and the report type is configured to periodic, the CSI report configuration can be valid only when the on-demand SSB resources is valid. For example, when the on-demand SSB is transmitted, the periodic CSI report configuration can be valid. When the on-demand SSB stops transmitting, the periodic CSI report configuration can be invalid.

In some embodiments, the CSI report configuration can be associated with one or more SSB resource types. For example, the CSI report configuration can be associated with on-demand SSB resources and/or periodic SSB resources. In some embodiments, when only periodic SSB transmitted on the cell, the SSB resources associated with the CSI report configuration can be the periodic SSB resources. In some embodiments, when there is on-demand SSB transmitted on the cell, the SSB resources associated with the CSI report configuration is the on-demand SSB resources. In some embodiments, when both on-demand SSB and periodic SSB are transmitted on the cell, the SSB resources associated with the CSI report configuration may include both the on-demand SSB resources and the periodic SSB resources.

In some embodiments, each of the one or more trigger states can be associated with one or more CSI report configurations. Each of the one or more trigger states can be associated with one or more OD SSB based CSI report configurations. In some embodiments, the one or more trigger states can be associated with at least one of: one or more entry numbers of one or more nzp-CSI-RS resource sets, one or more entry numbers of one or more csi-SSB resource sets, or one or more entry numbers of one or more csi-ODSSB resource sets. The association relationship described above may ensure that each trigger state can be associated with one or more resource sets. When a trigger state is indicated to take effect /function /operate, the associated resource sets can be taken into effect (e.g., be valid/active) . In some embodiments, the trigger state list may comprise one or more trigger states. Each trigger state of the trigger state list can be associated with one or more CSI report configurations. In certain embodiments, each trigger state of the trigger state list can be associated with one or more on-demand SSB based CSI report configurations.

In some embodiments, the trigger state list may comprise an aperiodic trigger state list and/or a SP on PUSCH trigger state list. In some embodiment, when the trigger state list is an aperiodic trigger state list, the trigger state within the trigger state list can be associated with more than one CSI report configuration. When the trigger state list is a SP trigger state list, the trigger state within the trigger state list can be associated with only one CSI report configuration.

In some embodiments, the one or more trigger states can be associated with at least one of: one or more entry numbers of one or more nzp-CSI-RS resource sets, one or more entry numbers of one or more csi-SSB resource sets, or one or more entry numbers of one or more csi-ODSSB resource sets. The association relationship described above may ensure that each trigger state can be associated with one or more resource sets. When a trigger state is indicated to take effect /function /operate, the associated resource sets can be taken into effect (e.g., be valid/applicable) . In some embodiments, the trigger state can be associated with at least one of: an entry number of a nzp-CSI-RS resource set, an entry number of a csi-SSB resource set, or an entry number of a csi-OD SSB resource set. For example, the value 1 of the entry number may correspond to the first entry of the resource set, the value 2 of the entry number corresponds to the second entry of the resource set, and so on. In some embodiments, the trigger state list may comprise one or more trigger states. Each trigger state can be associated with a report configuration information list. The report configuration information list may comprise one or more CSI report configuration information. The CSI report configuration information may comprise at least one of: an entry number of a nzp-CSI-RS resource set, an entry number of a csi-SSB resource set, or an entry number of a csi-ODSSB resource set.

In some embodiments, the first signaling may comprise at least one of: an indication of the OD SSB, an indication of an aperiodic CSI report, or an indication of a semi-persistent (SP) CSI report. According to the first signaling, the on-demand SSB transmission and/or the CSI report based on the on-demand SSB can be indicated. In some embodiments, the OD SSB can be associated with at least one of: a periodic CSI report configuration, a SP CSI report configuration, or an aperiodic CSI report configuration. For example, the first (triggering) signaling may comprise at least one of: an on-demand SSB indication, an aperiodic CSI report indication, or a semi-persistent (SP) CSI report indication. In some embodiments, the CSI report indication can be carried by the first signaling and can also be carried by the second signaling. The first signaling can be a downlink control information (DCI) , a MAC CE or a RRC signaling. In some embodiments, the on-demand SSB indication may indicate at least one of: activating the on-demand SSB resources, transmitting the on-demand SSB, stopping to transmit the on-demand SSB, or the transmission mode of the on-demand SSB. The transmission mode of the on-demand SSB may comprise at least one of: the on-demand SSB transmission times, the start of the on-demand SSB transmission, the duration that the on-demand SSB transmission within, or the indexes of the transmitted on-demand SSB. In some embodiment, the on-demand SSB can be associated with at least one of: a periodic CSI report configuration, a SP CSI report configuration, or a aperiodic CSI report configuration.

In some embodiments, when/if the on-demand SSB is indicated to be transmitted, the CSI report configuration associated with the on-demand SSB can be initiated. In some embodiments, the on-demand SSB can be associated with a trigger state. The trigger state can be associated with one or more aperiodic CSI report configurations. When/if the on-demand SSB is indicated to be transmitted, the trigger state associated with the on-demand SSB can be initiated.

In some embodiments, when/if the on-demand SSB is indicated to be transmitted, the aperiodic CSI report configuration associated with the on-demand SSB can be initiated. In some embodiments, when/if the on-demand SSB is indicated to be transmitted, the SP CSI report configuration associated with the on-demand SSB can be activated. The SP CSI report configuration associated with the on-demand SSB can be deactivated when/if the on-demand SSB stops transmitting.

In some embodiments, two signalings can be utilized for CSI reporting based on aperiodic reference signals. One can be used to activate aperiodic reference signal resources, and the other can be used to activate aperiodic or semi-persistent CSI reporting.

In some embodiments, the first signaling can initiate/active the on-demand SSB resources and the on-demand SSB based CSI report at the same time. For some examples, the first signaling may comprise an on-demand SSB transmission indication and a aperiodic CSI report indication. The aperiodic CSI report can be associated with the on-demand SSB resources. That is, the first signaling may indicate that the on-demand SSB resource is activated and the first signaling may initiate a aperiodic CSI report based on the on-demand SSB resources. For another example, the first signaling may comprise an on-demand SSB transmission indication and a SP CSI report indication. The SP CSI report can be associated with the on-demand SSB resources. That is, the first signaling may indicate that the on-demand SSB resource is activated and the first signaling may initiate a SP CSI report based on the on-demand SSB resources. In some other examples, the first signaling may comprise an on-demand SSB transmission indication. When the on-demand SSB is indicated to be transmitted, the CSI report based on the on-demand SSB resources can be initiated/activated. Through the first signaling, the on-demand SSB transmission indication and CSI reporting can be triggered at the same time, which can reduce the signaling overhead and the delay.

In some embodiments, the second signaling may comprise at least one of: an indication of an aperiodic CSI report, or an indication of a semi-persistent (SP) CSI report. In some embodiments, the indication of the aperiodic CSI report can be used to initiate at least one trigger state in the list of the one or more trigger states.

At least one of the first signaling or the second signaling (e.g., existing signaling configured to perform the indication) may comprise an aperiodic CSI report indication, or a semi-persistent (SP) CSI report indication. In some embodiments, the second signaling can be a DCI, a MAC CE, or a RRC signaling. In some embodiments, the second signaling may comprise at least one of: a DCI format 0_1, a DCI format 0_2, a DCI format 0_3, a SP CSI reporting on PUCCH Activation/Deactivation MAC CE, a new DCI format, or a new MAC CE.

In some embodiments, the aperiodic CSI report indication can be used/utilized to initiate one or more trigger states in a trigger state list. In some embodiments, the trigger state list can be an aperiodic trigger state. In some embodiments, the trigger state list can be configured by a medium access control control element (MAC CE) , or a radio resource control (RRC) signaling. In some embodiments, each trigger state of the trigger state list can be associated with one or more CSI report configuration. In some embodiments, each trigger state of the trigger state list can be associated with one or more on-demand SSB based CSI report configuration. The on-demand SSB based CSI report configuration can be associated with the on-demand SSB resources. In some embodiments, the aperiodic CSI report indication can be in a form of a codepoint. In some embodiments, each codepoint may map to a trigger state in the trigger state list. In some other embodiments, each codepoint may map to a trigger state associated with the on-demand SSB based CSI report configuration. In some embodiments, the aperiodic CSI report indication can be in a form of a bitmap. In other embodiments, each bit of the aperiodic CSI report indication may map to a trigger state associated with the on-demand SSB based CSI report configuration. The bit of the aperiodic CSI report indication may set to “1” to initiate the corresponding trigger state. For example, the first bit of the aperiodic CSI report indication may indicate the first trigger state within the trigger state list.

In some embodiments, the indication of the semi-persistent (SP) CSI report can be used to indicate an activation status or a deactivation status of one or more SP CSI report configurations. In some embodiments, each bit of the indication of the SP CSI report may correspond to a SP CSI report configuration or an OD SSB based SP CSI report configuration. The bitmap can effectively indicate the activation/deactivation of one or more SP CSI report configurations and can reduce bit overheads. In some embodiments, the SP CSI report indication can be used to indicate the activation/deactivation status of one or more SP CSI report configurations. In some embodiments, each of the one or more SP CSI report configurations may comprise/be a SP CSI report configuration or an on-demand SSB based SP CSI report configuration. The SP CSI report configuration may refer to a CSI report configuration with report type set to semi-persistent on PUCCH or semi-persistent on PUSCH. The on-demand SSB based SP CSI report configuration may refer to a CSI report configuration associated with the on-demand SSB resources. The report type of the CSI report configuration can be set to semi-persistent on PUCCH or semi-persistent on PUSCH.

In some embodiments, each bit of the SP CSI report indication may correspond to a SP CSI report configuration or an on-demand SSB based SP CSI report configuration. The bit of the SP CSI report indication can be set to 1 to indicate that the corresponding SP CSI report configuration can be activated. The bit of the SP CSI report indication can be set to 0 to indicate that the corresponding SP CSI report configuration can be deactivated. In some embodiments, the SP CSI report indication can be in a form of a codepoint. Each codepoint may map to a SP CSI report configuration or an on-demand SSB based SP CSI report configuration.

In some embodiments, the on-demand SSB may comprise at least one of: an on-demand/asynchronously/conditionally/unscheduled triggered/requested SSB, an aperiodic SSB, or a discontinuously-transmitted SSB. In some embodiments, the on-demand triggered SSB can be indicated by an indication signaling. In some embodiments, the on-demand triggered SSB can be transmitted when the on-demand triggered SSB indication signaling indicates the on-demand triggered SSB transmission. The on-demand triggered SSB indication signaling can be a downlink control information (DCI) , a MAC CE, a RRC signaling, or an uplink signaling. In some embodiments, the discontinuous transmitted SSB may refer to that the SSB is transmitted in duration 1 but not transmitted in duration 2, or the SSB is transmitted with transmission mode 1 in duration 1 and transmitted with transmission mode 2 in duration 2. At least one of: the duration 1, duration 2, transmission mode 1 or the transmission mode 2 can be determined by at least one of: RRC parameters, an indication signaling, or a timer. In some embodiments, the on-demand SSB can be used for at least one of: channel measurement, beam management, layer 1 signal to interference plus noise ratio (L1-SINR) computation, layer 1 reference signal received power (L1-RSRP) computation, or radio resource management.
