[0015] Turning to FIG. 1 , this figure shows a block diagram of one possible, non-limiting example in which embodiments may be implemented. Shown is a user equipment (UE) 110, a radio access network (RAN) node 170, and network element(s) 190. In the example of FIG. 1 , the user equipment (UE) 110 is in wireless communication with a wireless network 100. The UE is a wireless device that can access the wireless network 100. The UE 110 includes one or more processors 120, one or more memories 125, and one or more transceivers 130 interconnected via one or more buses 127. Each of the one or more transceivers 130 includes a receiver Rx 132 and a transmitter Tx 133. The one or more buses 127 may be an address bus, a data bus, or a control bus, and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, optical fiber, or other optical communication equipment. A "circuit" may include dedicated hardware or hardware associated with software executable thereon. The one or more transceivers 130 are connected to one or more antennas 128. The one or more memories 125 include computer program code 123. The UE 110 includes a module 140 consisting of one or both of modules 140-1 and / or 140-2, which may be implemented in many ways. The module 140 may be implemented in hardware as module 140-1, such as as part of one or more processors 120. The module 140-1 may also be implemented as an integrated circuit or via other hardware, such as a programmable gate array. In other embodiments, the module 140 may be implemented as computer program code 123 and as module 140-2 executed by one or more processors 120. For example, the one or more memories 125 and the computer program code 123, in conjunction with the one or more processors 120, may be configured to cause the user equipment 110 to perform one or more operations described herein. The UE 110 communicates with the RAN node 170 via a wireless link 111.

[0016] The RAN node 170 in this embodiment is a base station that provides access to the wireless network 100 for wireless devices such as the UE 110. The RAN node 170 may be, for example, a base station for 5G, also known as New Radio (NR). In 5G, the RAN node 170 may be an NG-RAN node, defined as either a gNB or an ng-eNB. The gNB is a node that provides NR user plane and control plane protocol terminations for UEs and is connected to the 5GC (e.g., network element(s) 190) via an NG interface. The NG-eNB is a node that provides E-UTRA user plane and control plane protocol terminations for UEs and is connected to the 5GC via an NG interface. The NG-RAN node may include multiple gNBs and may also include a central unit (CU) (gNB-CU) 196 and a distributed unit (DU) (gNB-DU), of which the DU 195 is shown. It should be noted that the DU may include a radio unit (RU) or may be coupled to and control the radio unit (RU). The gNB-CU is a logical node that hosts the RRC, SDAP, and PDCP protocols of the gNB or the RRC and PDCP protocols of the en-gNB and controls the operation of one or more gNB-DUs. The gNB-CU terminates the F1 interface connected to the gNB-DU. The F1 interface is illustrated as reference numeral 198, which also illustrates a link between a remote element of the RAN node 170 and a centralized element of the RAN node 170, such as between the gNB-CU 196 and the gNB-DU 195. The gNB-DU is a logical node that hosts the RLC, MAC, and PHY layers of the gNB or en-gNB, and some of its operations are controlled by the gNB-CU. One gNB-CU supports one or more cells. A cell is supported by only one gNB-DU. The gNB-DU terminates the F1 interface connected to the gNB-CU.It should be noted that while the DU 195 is considered to include the transceiver 160, e.g., as part of an RU, in some examples herein the transceiver 160 may be part of a separate RU, e.g., under the control of and connected to the DU 195. The RAN node 170 may also be an evolved NodeB (eNB) base station for long term evolution (LTE), or any other suitable base station, access point, access node, or node.

[0017] The RAN node 170 includes one or more processors 152, one or more memories 155, one or more network interfaces (N / WI / F(s)) 161, and one or more transceivers 160 interconnected via one or more buses 157. Each of the one or more transceivers 160 includes a receiver Rx 162 and a transmitter Tx 163. The one or more transceivers 160 are connected to one or more antennas 158. The one or more memories 155 include computer program code 153. The CU 196 may include the processor 152, the memory 155, and the network interface 161. Note that the DU 195 may also include its own memory / storage and processor(s), and / or other hardware, which are not shown.

[0018] The RAN node 170 includes a module 150, which may be implemented in many ways, consisting of one or both of modules 150-1 and / or 150-2. The module 150 may be implemented in hardware as module 150-1, such as as part of one or more processors 152. The module 150-1 may also be implemented as an integrated circuit or via other hardware, such as a programmable gate array. In other embodiments, the module 150 may be implemented as module 150-2, which is implemented as computer program code 153 and executed by one or more processors 152. For example, the one or more memories 155 and the computer program code 153, in conjunction with the one or more processors 152, are configured to cause the RAN node 170 to perform one or more operations described herein. It should be noted that the functionality of the module 150 may be distributed, such as distributed between the DU 195 and the CU 196, or may be implemented solely in the DU 195.

[0019] One or more network interfaces 161 communicate over a network, such as via links 176 and 131. One or more gNBs 170 may communicate, for example, using link 176. Link 176 may be wired or wireless or both, and may implement, for example, an Xn interface for 5G, an X2 interface for LTE, or other suitable interface for other standards.

[0020] The bus(es) 157 may be an address bus, a data bus, or a control bus, and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, optical fiber or other optical communication equipment, a radio channel, etc. For example, one or more transceivers 160 may be implemented as a remote radio head (RRH) 195 for LTE or a distributed unit (DU) 195 for a gNB implementation for 5G, and other elements of the RAN node 170 may be in a physically different location from the RRH / DU in some cases, and the bus(es) 157 may be implemented in part as, for example, an optical fiber cable or other suitable network connection for connecting other elements (e.g., a central unit (CU) of the RAN node 170, gNB-CU) to the RRH / DU 195. Reference numeral 198 indicates those appropriate network links.

[0021] It should be noted that while the description herein refers to a "cell" performing a function, it is clear that the equipment forming the cell performs the function. A cell constitutes part of a base station; that is, there can be multiple cells per base station. For example, there can be three cells for one carrier frequency and associated bandwidth, with each cell covering one-third of a 360-degree area, so that the coverage area of ​​a single base station roughly covers an ellipse or circle. Furthermore, each cell corresponds to one carrier, and a base station can use multiple carriers. That is, if there are three 120-degree cells per carrier and two carriers, the base station has a total of six cells.

[0022] The wireless network 100 may include core network functions and may include network element(s) 190 that provide connectivity via links or links 181 with additional networks, such as telephone networks and / or data communication networks (e.g., the Internet). Such core network functions for 5G may include access and mobility management functions (AMF(s)) and / or user plane functions (UPF(s)) and / or session management functions (SMF(s)). Such core network functions for LTE may include a mobility management entity (MME) / serving gateway (SGW) function. Note that these are merely example functions that may be supported by the network element 190, and that both 5G and LTE functions may be supported. The RAN node 170 is coupled to the network element 190 via link 131. Link 131 may be implemented, for example, as an NG interface for 5G, or an S1 interface for LTE, or other appropriate interface for other standards. Network element 190 includes one or more processors 175, one or more memories 171, and one or more network interfaces (N / WI / F(s)) 180 interconnected via one or more buses 185. The one or more memories 171 include computer program code 173. The one or more memories 171 and computer program code 173 are configured, by the one or more processors 175, to cause network element 190 to perform one or more operations.

[0023] The wireless network 100 may implement network virtualization. Network virtualization is the process of combining hardware and software network resources and network functions into a single software-based management entity: a virtual network. Network virtualization includes platform virtualization and is often combined with resource virtualization. Network virtualization can be classified as external, which consolidates many networks or network portions into a virtual unit, or internal, which provides network-like functionality in software containers on a single system. For example, a network may be deployed in a telecommunications cloud, with virtualized network functions (VNFs) running on servers, for example, in a data center. For example, the network core functions and / or the radio access network (e.g., CloudRAN, O-RAN, edge cloud, etc.) may be virtualized. Note that the resulting virtualized entities of network virtualization are still implemented at some level using hardware, such as processor 152 or 175 and memory 155 and 171, and that such virtualized entities produce technical effects.

[0024] Also, it should be noted that the operations of the exemplary embodiments of the present disclosure may be performed by multiple cooperating devices (e.g., cRANs).

[0025] The computer-readable memories 125, 155, and 171 may be of any type suitable for the local technology environment and may be implemented using any suitable data storage technology, such as semiconductor-based memory devices, flash memory, magnetic memory devices and systems, optical memory devices and systems, fixed memory, removable memory, etc. The computer-readable memories 125, 155, and 171 may be means for performing storage functions. The processors 120, 152, and 175 may be of any type suitable for the local technology environment and may include, by way of non-limiting example, one or more of a general-purpose computer, a special-purpose computer, a microprocessor, a digital signal processor (DSP), and a processor based on a multi-core processor architecture. The processors 120, 152, and 175 may be means for performing functions such as controlling the UE 110, the RAN node 170, and other functions, as described herein.

[0026] In general, various exemplary embodiments of user equipment 110 may include, but are not limited to, mobile phones such as smartphones, tablets, personal digital assistants (PDAs) with wireless communication capabilities, portable computers with wireless communication capabilities, image capture devices such as digital cameras with wireless communication capabilities, gaming devices with wireless communication capabilities, music storage and playback appliances with wireless communication capabilities, Internet appliances that enable wireless Internet access and browsing, tablets with wireless communication capabilities, and portable units or terminals incorporating combinations of such capabilities.

[0027] Having thus provided one suitable, but non-limiting, technical background for practicing exemplary embodiments of the present disclosure, the exemplary embodiments will now be described in more detail.

[0028] The features in this embodiment generally relate to network energy conservation, for example, in the radio access network, which consumes a large portion of the total energy consumption in the network. In 3GPP Rel. 18, RP-213554 aims to specify transmission and / or reception adaptation techniques in the time, frequency, space, and power domains, with potential support / feedback from the UE, potential UE assistance information, and information exchange / coordination over the network interface. This is described in the summary section of Rl-2205554 "FL summary_109-e-Netw_Energy_NR-03_v091_moderator."

[0029] Energy savings in the network can be achieved, for example, by using less frequent synchronization signal block (SSB) transmissions, e.g., using an SSB periodicity of 160 ms in empty / low load situations in 5G non-standalone (NSA) deployments.

[0030] Network energy savings can be achieved, for example, through discontinuous transmission (DTX) techniques. For example, radio units (e.g., power amplifiers (PAs)) can be turned on and off when they do not need to transmit. With improvements in hardware and software capabilities, PA shutdown on an orthogonal frequency division multiplexing (OFDM) symbol basis may become possible and become commonly applied in commercial networks. This is called micro-DTX (μDTX).

[0031] NW energy savings may be achieved, for example, by a complete cell switch-off (i.e., cell shutdown), which may turn off most of the hardware components of a cell, frequency layer, or RAN site.

[0032] Network energy savings can be achieved, for example, by shutting down additional components such as transmit antenna elements and corresponding baseband circuitry. Adjusting the number of active TRXs and the cell's Tx power can be used as a potential method for base station power savings. For example, the number of active TRX chains can be reduced in low-load conditions and depending on the UE's location within the cell (e.g., cell edge vs. cell center). Similarly, as shown in Figure 2, transmit power levels can be dynamically adjusted to utilize transmit capacity and minimize power amplifier power consumption (and therefore total power consumption) when operating at lower Tx power levels. Referring now to Figure 2, an example of power amplifier power consumption (y-axis) as a function of transmit power per active antenna for two physical Tx antennas (x-axis) is shown. One or more physical antennas can be mapped to one or more logical antenna ports. For example, two logical antenna ports may be mapped to one physical antenna port. For example, one logical antenna port may be mapped to multiple physical antenna ports. Note that the PA power consumption in the example of Figure 2 increases as the transmit power per active antenna increases. From the viewpoint of power saving of the network, the network can consider reducing the number of active antennas utilized when the network is empty / low load in order to achieve power saving of the network.

[0033] Note that logical antenna ports correspond to specific reference signals. These reference signals may be used by the UE to derive channel state information associated with the logical antenna port. One example of a reference signal corresponding to a logical antenna port is a channel state information reference signal (CSI-RS).

[0034] The features described herein relate to the CSI-RS. The CSI-RS can be used for various purposes in NR. For example, it may be used for DL ​​CSI acquisition. It may also be used to derive measurements for mobility and beam management, as well as for interference measurements. Currently, in NR, a UE may be configured with one or more CSI-RS resource sets, and each CSI-RS resource set may include one or more configured CSI-RS resources or SSB-block resources.

[0035] CSI-RS resource sets can operate periodically, semi-periodically, or aperiodically. CSI-RS resources consist of up to 32 logical antenna ports, with configurable density. In the time domain, CSI-RS resources can start at any OFDM symbol of a slot and can span one, two, or four OFDM symbols, depending on the number of configured ports. Similarly, UE measurement reporting of CSI can operate in a periodic, semi-periodic, or aperiodic manner, which are the so-called report types in the NR reporting configuration. However, UE periodic reporting may be constrained to operate only based on the configured periodic CSI-RS resource set. UE semi-persistent reporting may operate based on both the configured periodic and semi-persistent CSI-RS resource sets. UE aperiodic reporting may operate based on periodic, semi-persistent, and aperiodic CSI-RS resource sets. In summary, periodic CSI-RS resources are used to generate any report type, semi-persistent CSI-RS and periodic CSI-RS resources are used to generate semi-persistent CSI reports, and aperiodic CSI-RS is only used to generate aperiodic reports.

[0036] In NR, as mentioned above, the configuration related to CSI-RS transmission may include a list of CSI-RS resource sets (see CSI-ResourceConfig in TS 38.331), each of which may contain specific CSI-RS resources. For semi-persistent and aperiodic CSI-RS, the actual triggering of CSI-RS transmission is done per CSI-RS resource set via a Medium Access Control (MAC) Control Element (CE) or Downlink Control Information (DCI).

[0037] The resource set may be used as part of the UE reporting configuration, which describes what is measured and the corresponding measurement reports the UE should make. Specifically, if the CSI-RS resource set is configured as "aperiodic" by radio resource control (RRC) signaling, the CSI-RS resource set configuration may include a slot offset (periodicTriggeringOffset) that defines the time interval between the triggering DCI and CSI-RS transmission. When aperiodic CSI-RS is triggered, the gNB transmits CSI-RS according to the slot offset defined in the RRC signaling, and the UE is expected to receive CSI-RS within the indicated slot.

[0038] In addition to non-zero-power channel state information reference signals (NZP-CSI-RS), which may be used for procedures such as channel measurement, beam management, beam measurement, and / or connected mode mobility, zero-power channel state information reference signals (ZP-CSI-RS) may also be configured. These may be empty resource elements (REs) that can be used for interference measurements. Empty REs may or may not be monitored by the UE to perform interference measurements. These REs may not contain the UE's transmissions but may contain transmissions of other UEs. These REs may puncture the physical downlink shared channel (PDSCH), so the UE cannot expect to receive DL data therein. In other words, ZP-CSI-RS is used to configure the RE puncturing pattern for the PDSCH when some REs are allocated for other purposes.

[0039] TS 38.214 describes CSI-RS as follows: "...5.2.2.3 Reference signal (CSI-RS) 5.2.2.3.1 NZP CSI-RS The UE is configured with one or more NZP CSI-RS resource set configurations as indicated by the higher layer parameters CSI-ResourceConfig and NZP-CSI-RS-ResourceSet, where each NZP CSI-RS resource set contains K >= 1 NZP CSI-RS resources. The following parameters, which the UE assumes to have a non-zero transmit power for CSI-RS resources, are configured via the higher layer parameters NZP-CSI-RS-Resource, CSI-ResourceConfig, and NZP-CSI-RS-ResourceSet for each CSI-RS resource configuration. - nzp-CSI-RS-ResourceId determines the CSI-RS resource configuration ID. ... - resourceMapping defines the number of ports, CDM type, OFDM symbol and subcarrier occupancy of the CSI-RS resource in a slot. - nrofPorts in resourceMapping defines the number of CSI-RS ports, the allowed values ​​are listed in clause 7.4.1.5 of [4, TS 38.211]. ... - powerControlOffset: The ratio of the PDSCH EPRE to the NZP CSI-RS EPRE assumed when the UE derives CSI feedback, and takes values ​​in the range of [-8, 15] dB with a step size of 1 dB. For CQI calculation based on NZP CSI-RS resource pairs, the powerControlOffset of each NZP CSI-RS resource in the NZP CSI-RS resource pair for channel measurement is the assumed ratio of the EPRE when the UE derives CSI feedback, and takes values ​​in the range of [-8, 15] dB with a step size of 1 dB. - powerControlOffsetSS: the expected ratio of NZP CSI-RS EPRE to SS / PBCH block EPRE. ... - The BWP-Id in the CSI-ResourceConfig defines in which bandwidth part the configured CSI-RS is located. ... With the exception of the NZP CSI-RS resource used for interference measurements, all CSI-RS resources in a set are configured with the same density and the same nrofPorts. 5.2.2.4 Channel State Information - Interference Measurement (CSI-IM) A UE may be configured with one or more CSI-IM resource set configurations, as indicated by the higher layer parameter CSI-IM-ResourceSet, where each CSI-IM resource set consists of K≧1 CSI-IM sources. ... 5.2.2.5 CSI Reference Resource Definitions ... When deriving CSI feedback, the UE does not assume that the NZP CSI-RS resources for channel measurement overlap with the CSI-IM resources for interference measurement or the NZP CSI-RS resources for interference measurement. 5.1.4.2 PDSCH resource mapping with RE level granularity ... Within the BWP, the UE configures one or more ZP CSI-RS resource set configurations for aperiodic, semi-periodic, and periodic time-domain operation (the higher layer parameters periodic-ZP-CSI-RSResourceSetsToAddModList, sp-ZP-CSI-RS-ResourceSetsToAddModList, and p-ZP-CSI-RS-ResourceSet are included in PDSCH-Config, respectively). Each ZP CSI-RS resource set consists of up to 16 ZP CSI-RS resources (the higher layer parameter ZP-CSI-RS-Resource) in the BWP arithmetic. REs indicated by p-ZP-CSI-RS-ResourceSet are declared unavailable for PDSCH use. REs indicated by sp-ZP-CSI-RSResourceSetsToAddModList and aperiodic-ZP-CSI-RSResourceSetsToAddModList are declared unavailable for PDSCH use when triggering and activation are applied, respectively.

[0040] Although the term "ZP-CSI-RS" is used in this disclosure, this is not intended to be limiting, and other names such as "enhanced ZP-CSI-RS" or any other name used to refer to resources that a UE is not required or expected to utilize / recognize, such as CSI-RS, may be used. In other words, ZP-CSI-RS resources may puncture other channels / signals (e.g., PDSCH) or other channels / signals (e.g., PDSCH), and ZP-CSI-RS may be multiplexed by rate matching. Also, it should be noted that in this disclosure, ZP-CSI-RS and CSI-IM may be used interchangeably, and where one term is used, the other term may also be used.

[0041] 3, there is illustrated an example of a CSI-RS configuration including an NZP-CSI-RS (310), a CSI-IM (320), and a ZP-CSI-RS (330). Note that the assignments / descriptions of the NZP-CSI-RS (310) and ZP-CSI-RS (330) each include a CSI-RS-ResourceMapping attribute that includes an indication of the number of ports, nrofPorts.

[0042] As per R1-220554, in RAN1#109, the following agreement was reached regarding adaptive techniques in the spatial domain, which will be considered as part of study item RP-213554: "...further research techniques and extensions for adaptation of the number of spatial elements in gNB: Note: Spatial elements include antenna elements, TxRUs (sub-arrays / full connections), antenna panels, TRxPs (co-located or geographically separated), and logical antenna ports (corresponding to specific signals and channels). For example, measurements, CSI feedback, power control, PUSCH / PDSCH repetition, SRS transmission, TCI configuration, beam management, beam failure recovery, radio link monitoring, cell (re)selection, handover, initial access, etc. Feedback / assistance information from the UE required to support dynamic spatial element adaptation For example, CSI measurement and reporting, SR, etc. Signaling method including reduced signaling that allows dynamic spatial element adaptation For example, group-wide L1 signaling, broadcast signaling, MAC CE, etc. Dynamic TRxP Adaptation Consideration of trigger ON / OFF conditions for TRxP(s) This does not affect the specification and may be up to the network implementation. Reconfiguration of SSB, PL-RS, TRS and CSI-RS and investigation of the impact on initial access procedures, synchronization and measurements performed by idle / inactive / connected UEs Dynamic logical port adaptation and efficient port reconfiguration Find out the signaling details of the port (e.g. NZP CSI-RS port) if the UE needs to know them. We study dynamic adaptation (including activation / deactivation) of CSI measurement or reporting configurations for port adaptation. Co-adapt spatial, frequency and power domain settings to avoid coverage loss..."

[0043] Dynamically switching antenna elements (e.g., entire TxRUs or TRxPs) on / off impacts the number of logical antenna ports that a gNB supports / uses at a given time. This means that certain CSI-RS (logical) ports (mapped to shut-down physical antenna ports) may need to be muted. While it may be beneficial for a UE to receive signaling information regarding which CSI-RS ports are muted or disabled, e.g., to avoid unpredictable UE behavior, this may lead to high signaling overhead if the switching is dynamic (e.g., frequent). A technical effect of an example embodiment of the present disclosure may be more efficient signaling of CSI-RS port reconfiguration and / or scheduling.

[0044] In an exemplary embodiment, a gNB may configure a UE with at least two CSI-RS resource set configurations (e.g., Config-Id1 and 2), which may be associated with (i.e., correspond to) each other. In an exemplary embodiment, each CSI-RS resource set configuration may consist of the same CSI-RS resources / REs (e.g., for a given UE's bandwidth portion (BWP)), each consisting of both NZP-CSI-RS and ZP-CSI-RS / CSI-IM RS. In an exemplary embodiment, each CSI-RS resource set configuration may differ at least with respect to the number of ports assigned to the NZP-CSI-RS and ZP-CSI-RS / CSI-IM RS resources.

[0045] In an example embodiment, at least one resource / RE associated with an NZP-CSI-RS in a first configuration having nrofPortsNZP (i.e., defining the number of NZP-CSI-RS ports) may be associated with a ZP-CSI-RS / CSI-IM RS in a second configuration having nrofPortsZP / IM (i.e., defining the number of ZP-CSI-RS ports or CSI-IM ports).

[0046] In an example embodiment, the muting of a particular CSI-RS port (on which the network will not perform CSI-RS transmissions after muting the corresponding logical antenna port) may be signaled to the UE by defining the muted port as a ZP-CSI-RS port (or CSI-IM port).

[0047] In this disclosure, for simplicity and without loss of generality, it may be assumed that a mute port is defined as a ZP-CSI-RS port, however, this is not limiting and a mute port may alternatively be defined as a CSI-IM port.

[0048] In an exemplary embodiment, the actual configuration used by the UE may be instructed by the network using L1 / L2 signaling (e.g., by sending a DCI or MAC CE pointing to the desired Config-Id). For example, if the network wants to mute some CSI-RS ports, the network may use L1 / L2 signaling to instruct the UE to switch from the currently used configuration to a configuration that includes the ZP-CSI-RS ports (i.e., the muted ports). Because there is a relationship between the two configurations, they may be considered mutually exclusive, and activation of one configuration may implicitly (i.e., without explicit signaling from the network) trigger deactivation of the associated configuration. Additionally, or instead, each configuration may be considered "active," but one configuration may override the other.

[0049] In an exemplary embodiment, at least two configurations are associated with one another, for example, by adding the config ID of one configuration to (eg, a field of) the other configuration.

[0050] In an exemplary embodiment, to unmute a muted RE or port, the network can activate the corresponding NZP-CSI-RS or deactivate the ZP-CSI-RS that caused the RE / port to be muted. In other words, deactivating a ZP-CSI-RS (e.g., via MAC CE or DCI) may be considered by the UE as unmuting a previously muted RE / port (using that ZP-CSI-RS). Additionally or alternatively, each configuration may be considered “active,” but one configuration may override the other, including muted / disabled ports. In an exemplary embodiment, the network can send an instruction to activate a resource set configuration and / or an instruction to deactivate a resource set configuration to the user equipment.

[0051] In an exemplary embodiment, the UE may not assume that "muted" REs (defined as ZP-CSI-RS-Resources) are "empty" resource elements (REs). Instead, those REs may be used by the network to transmit PDSCH (e.g., to carry a PDSCH payload). The network may instruct the UE whether "muted" REs / ports (e.g., defined as ZP-CSI-RS resources or ports) should be assumed empty (e.g., for PDSCH mapping and rate matching assumption purposes at the UE). This indication may be made, for example, via a DCI or MAC CE that activates the ZP-CSI-RS resources, via a new field / bit, or using an existing / reserved bit / field. In an exemplary embodiment, the UE may not assume that a device's (e.g., a base station's) NZP-CSI-RS resources may not be mapped to resource elements corresponding to the configured ZP-CSI-RS resources. Instead, it may be assumed that those NZP-CSI-RS REs are used for the device's (e.g., a base station's) PDSCH transmission. Additionally or alternatively, the ZP-CSI-RS configuration may include information on whether muted REs / ports should be assumed to be "empty." When the network activates / triggeres this configuration for the UE, the UE can determine what the assumption is for the corresponding muted / disabled REs / ports (e.g., whether a PDSCH is mapped to the corresponding resource). The UE can monitor REs from muted / disabled logical antenna ports for PDSCH only.

[0052] Referring now to FIG. 4, a signaling diagram according to example embodiment(s) of the present disclosure is illustrated. At 415, a UE (405) may be RRC connected to a cell (410), which may be, for example, a base station or a gNB. At 420, the cell (410) may make a decision to use CSI-RS port adaptation, for example, according to an example embodiment of the present disclosure. At 425, the cell (410) may transmit at least two CSI-RS configurations, such as CSI-RS config-id1 and an associated CSI-RS config-id2, to the UE (405). For example, the UE (405) may be configured with one or more NZP CSI-RS resource set configuration(s). Each resource set configuration may be configured with K>=1 NZP CSI-RS resources, and each NZP CSI-RS resource may be configured with a number of ports, nrofPorts. The same applies to other types of resources (ZP, CSI-IM, etc.).

[0053] Config-id 1 and Config-id 2 may contain the same total number of REs (totREs=p1) and occupy specific time and frequency resources. Config-id 1 in this embodiment may contain all REs mapped only to NZP-CSI-RSs with a large number of ports (r), defined as nrofPortsNZP1 (e.g., p1=32). Config-id 1 is used when CSI-RS port muting is not used. Config-id 2 in this embodiment may contain specific REs (out of total REs) mapped to NZP-CSI-RSs associated with a smaller number of ports (nrofPortsNZP2, e.g., p2=16) than Config-id 1. p2 = 16), the remaining RE is mapped to ZP-CSI-RS and consists of the number of remaining (muted) ports (i.e., p3 = number of muted ports = nrofPortsZP = nrofPortsNZP1 - nrofPortsNZP2 = p1 - p2, e.g., 16). config-id2 may be intended to be used when a large number of ports (nrofPortsNZP1 to nrofPortsNZP2) are muted. To allow flexibility in network operation, multiple configurations can be assigned to a UE with different numbers of muted ports.

[0054] At 430, the cell (410) may send signaling to the UE (405) to activate CSI-RS config-id1 (NZP resource). In an exemplary embodiment, the actual configuration the UE uses may be indicated by the network using L1 / L2 signaling (such as DCI or MAC CE), pointing to the desired configuration (with Config-id) to be activated, which may be mutually exclusive with respect to an associated configuration that is implicitly deactivated by the UE.

[0055] L1 / L2 signaling may be configured / achieved via DCI. In an exemplary embodiment, a group-common DCI common to multiple UEs in a cell may be used to switch CSI-RS configuration IDs for multiple UEs at once (such as Format 2_1 or Format 1_0 scrambled by SI-RNTI or other existing or new formats). This allows for more efficient signaling, such as when multiple UEs are present in a cell.

[0056] In this embodiment, the network can configure a pair (or trio or quartet, etc.) of configurations configured to indicate non-muting and muting of resources with the same identifier to all UEs in the cell (e.g., non-muting with id1, first muting with id2, second muting with id3, etc.). In this way, L1 / L2 signaling can indicate the same muting to all UEs with a single configuration ID.

[0057] In one example, L1 / L2 signaling can indicate an index that points to which pair / trio / quartet / etc. configuration to activate, regardless of the actual configuration identifiers assigned to the associated configurations. For a pair of associated configurations, the network can indicate use of either the first or second configuration. For a trio of associated configurations, the network can indicate use of the first, second, or third configuration.

[0058] At 435, the UE (405) may use CSI-RS config-id1 to receive CSI-RS. Based on CSI-RS config-id1, the UE (405) may assume that no ports are muted and may implicitly deactivate the associated CSI-RS config-id2. For example, the UE (405) may receive one or more CSI-RS 440, which may be CSI-RS transmissions sent by the cell (410) based on the assumption (445) that no ports are muted.

[0059] At 450, the cell (410) may decide to mute a particular CSI-RS port. At 455, the cell (410) may send signaling to the UE (405) to activate CSI-RS config-id2 (NZP+ZP resources). At 460, the UE (405) may use CSI-RS config-id2 to receive CSI-RS assuming the p3 port is muted, assume empty REs for the muted port (if configured), and implicitly deactivate the associated CSI-RS config-id1. For example, the UE (405) may receive one or more CSI-RS 470, which may be CSI-RS transmissions sent by the cell (410) based on the muted port assumption (465).

[0060] Referring now to FIG. 5, an example of a cell with eight ports operating in accordance with an exemplary embodiment of the present disclosure is illustrated, e.g., when the network decides to configure a UE with two CSI-RS configurations that are associated with each other. Chart 510 illustrates an example first configuration, and chart 520 illustrates an example second configuration. In the first configuration, there may be no muting, which may be indicated to the UE by nrofPortsNZP1=8. In the second configuration, there may be muting, which may be indicated to the UE by nrofPortsNzp2=4 and nrofPortsZP=4. In other words, in the second configuration, the UE may be considered muted because four ports are assigned to ZP-CSI-RS. These four ports may have been designated as NZP-CSI-RS ports in the first configuration. In the example of FIG. 5, the eight-port configuration (corresponding to row 7 of Table 7.4.1.5.3-1 of TS38.211) may be switched to a four-port configuration (corresponding to row 4 of the same table).

[0061] A technical effect of an example embodiment of the present disclosure is to enable, for a given UE, the same resource to be used as an NZP-CSI-RS resource (e.g., in a first configuration) and as a ZP-CSI-RS resource (e.g., in a second configuration) at different times. In an example embodiment, overlapping resources may "implicitly" mean to the UE that such resources are muted in a configuration where they are defined as ZP-CSI-RS resources, or that they are muted when such ZP-CSI-RS is activated.

[0062] In an example embodiment, ZP-CSI-RS allocation for NZP-CSI-RS muting may be provided under the "NZP-CSI-RS-ResourceSet" configuration or as part of an enhanced "NZP-CSI-RS-ResourceSet." While this disclosure generally refers to using ZP-CSI-RS to mute NZP-CSI-RS, ZP-CSI-RS can also be used to mute SSBs. For example, if ZP-CSI-RS is provided in the "CSI-SSB-ResourceSet" configuration, the corresponding SSB can be muted. Alternatively, it can be provided in a new "ZP-CSI-RS-ResourceSet" configuration.

[0063] In an example embodiment, the gNB may achieve micro-DTX on one or more OFDM symbols to which the ZP-CSI-RS port is mapped. This may be achieved by allocating NZP-CSI-RS ports on the same time domain resource (OFDM symbol(s)) for multiple / all UEs such that micro-DTX is used on these same OFDM symbols where the NZP-CSI-RS ports of these UEs are muted.

[0064] Another issue associated with switching off TxRUs / antenna elements is the potential loss of coverage due to reduced beamforming gain from the gNB's Tx RUs / panels. A technical effect of exemplary embodiments of the present disclosure is to prevent loss of coverage. In exemplary embodiments, neighboring gNBs may configure non-contiguous sets of NZP-CSI-RSs to be muted (and therefore assigned as ZP-CSI-RS), which may have the technical effect of enabling the respective UEs to perform DL interference measurements on the muted CSI-RSs. This may have the technical effect of enabling the UEs to perform better DL interference measurements, thereby compensating to some extent for the loss of beamforming gain. Referring now to FIG. 6, an example of beamforming gain loss when using antenna port muting is illustrated. When transmitting with one antenna (630), a cell / base station (610) may experience a loss of beamforming gain compared to transmitting to a UE (620) with eight antennas (640). A technical effect of example embodiments of the present disclosure may be to compensate for loss of beamforming gain, for example, by using no-signal interference measurements to calculate better covariance or other statistics, which may have the technical effect of achieving better channel quality indicator (CQI) reporting and / or PDSCH demodulation with a receiver that performs interference cancellation (e.g., MMSE-IRC).

[0065] In an alternative exemplary embodiment, the network may configure the UE with at least one CSI-RS resource set configuration that includes NZP-CSI-RS resources and ports, and may further include new information for at least one port indicating that at least one port may be muted (i.e., at least one port may be marked as "for muting" or "muted", etc.). The network may indicate to the UE (e.g., via L1 / L2 signaling) when the muting status applies.

[0066] In another exemplary embodiment, the network may configure the UE with information about which ports are muted (i.e., ports marked with ZP-CSI-RS) and indicate to the UE (via L1 / L2 signaling) when muting will occur. This may have the technical effect of allowing the UE to omit receiving CSI-RS resources mapped to muted ports. In another exemplary embodiment, the network may configure the UE with information about which ports may potentially be muted (e.g., by marking these ports with dynamic muting / potential ZP tags). However, the network may not send L1 / L2 signaling indicating which ports are muted. Instead, the UE may monitor all configured CSI-RS resources and perform blind detection to determine whether ports marked for dynamic muting are currently active. While this may have the technical effect of increasing UE complexity and power consumption, low false detections and low false positive detections are expected, at least for UEs located toward cell centers with high SINR. The network can, for example, activate muting according to this variant depending on the radio quality (e.g., SINR / RSRP / RSRQ / CQI) reported by the UE. Additionally or alternatively, the network can use this variant if the "muting period" is much larger than the NZP-CSI-RS periodicity, e.g., Tmute >> TNZP-CSI-period. In this case, even UEs with low SINR / RSRP can detect muting using blind detection over multiple NZP-CSI-RS occasions. Furthermore, in this case, a static value for minimum Tmute is defined, after which the UE may need to perform blind detection of muting again. This can be defined as follows: Express Tmute_min as an absolute value in milliseconds / seconds. Let Tmute_min be N*TNZP-CSI-period, where N is an integer.

[0067] A technical effect of the example embodiments of the present disclosure may be to leverage the ZP-CSI-RS / CSI-IM framework to dynamically turn antenna ports on and off. In contrast to legacy configuration(s) of ZP-CSI-RS under PDSCH-Config (or CSI-IM-ResourceSet), the configuration of ZP-CSI-RS in the example embodiments of the present disclosure may be under (and associated with) NZP-CSI-RS-ResourceSet configuration (or CSI-SSB-ResourceSet).

[0068] A technical effect of an example embodiment of the present disclosure may be to enable partial recovery from loss of coverage due to a reduction in the number of antennas / TxRUs by reusing muted NZP-CSI-RS for CSI-IM resources and coordinating this among neighboring cell(s).

[0069] A technical effect of an example embodiment of the present disclosure may be to enable efficient signaling for directing muting of CSI-RS resources, including enabling simultaneous activation of muting for multiple UEs.

[0070] A technical effect of the exemplary embodiments of the present disclosure is to reduce the required DL signaling overhead, since port muting as well as ZP-CSI-RS may be conveyed / triggered using the same message.

[0071] 7 illustrates potential steps of an example method 600. The example method 700 may include receiving (710) at least two resource set configurations, where a first configuration of the at least two resource set configurations includes an indication that a first number of ports are mapped to a first resource set used for a first type of resource, and a second configuration of the at least two resource set configurations includes an indication that the first number of ports are mapped to a first resource set used for a second type of resource, the first type of resource being different from the second type of resource; determining (720) to use one of the at least two resource set configurations; and receiving (730) at least one reference signal based at least in part on the determined configuration of the at least two resource set configurations. The example method 700 may be performed, for example, in a user equipment. The second configuration may include indicating that a second number of ports are mapped to a second set of resources used for the first type of resource. The first set of resources and the second set of resources may each include different resources.

[0072] 8 illustrates potential steps of an example method 800. The example method 800 may include transmitting (810) at least two resource set configurations to at least one user equipment, where a first configuration of the at least two resource set configurations includes an indication that a first number of ports are mapped to a first resource set used for a first type of resources and a second configuration of the at least two resource set configurations includes an indication that the first number of ports are mapped to a first resource set used for a second type of resources, where the first type of resources are different from the second type of resources; transmitting (820) to the at least one user equipment an indication to activate one of the at least two resource set configurations; and transmitting (830) to the at least one user equipment at least one reference signal based at least in part on the indicated configurations of the at least two resource set configurations. The example method 800 may be performed in, for example, a cell, a network node, a base station, a gNB, etc.
