AI Technical Summary
In wireless communication systems, user equipment (UE) faces challenges in performing time domain channel property (TDCP) measurements due to limited buffer capacity, leading to incomplete or inaccurate channel reporting, inefficient resource utilization, and reduced communication reliability.
The UE transmits capability information to the network entity indicating a threshold quantity of concurrently active reference signal resources supported for TDCP measurements across multiple component carriers. The network entity schedules reference resources to ensure that the quantity of active reference signal resources in each time duration does not exceed this threshold, allowing the UE to effectively perform TDCP measurements without exceeding its buffer capacity.
This approach enables more efficient scheduling of CSI-RS resources, improves the accuracy of TDCP reports, reduces signaling overhead, and enhances the reliability of wireless communication by ensuring that TDCP measurements are completed without buffer overflow.

These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communication system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) .
[0004] The UEs may provide various reports to a network entity, such as channel state information, which can be utilized to update or improve various wireless communication procedures. The UEs may perform measurements, such as CSI measurements, based on reception of reference signals (for example, channel state information reference signals) . The network entity may configure the UEs with reference signal resources in one or more sets of reference signal resources, which may have different periodicities, quantities of reference signal resources per slot, and / or different total quantities of reference signals. In some cases, the UEs may be mobile and moving at relatively-high velocity. In such examples, instantaneous measurements may not accurately capture channel properties over time.SUMMARY

[0027] In some wireless communication systems, a user equipment (UE) may be scheduled to perform various measurements, which may include time domain channel property (TDCP) measurements. The UE may be configured with one or more sets of reference signal resources (for example, channel state information (CSI) reference signal (RS) resources) , and may perform the TDCP measurements over a duration (for example, in one or more CSI-RS resources across multiple time durations (for example, multiple slots) ) . A delay related to the duration refers to an amount of time for TDCP measurements between a first reference signal resource (for example, a first CSI-RS resource) and a subsequent (for example, a last) reference signal resource (for example, a second CSI-RS resource) . For example, the amount of time spans a quantity of slots during which the UE maintains buffered downlink signaling (for example, buffered CSI-RSs) and performs the TDCP measurements via CSI-RS resources for a given TDCP report. However, a size of a UE buffer (for example, an amount of available storage for receiving CSI-RSs and performing measurements) may be limited, and as such, the UE may not be capable of supporting measurements across a group of CSI-RS resources (for example, may not be able to buffer a sufficient amount of CSI-RSs to enable the UE to perform measurements) . Active CSI-RS resources may refer to CSI-RS resources that are active for TDCP measurements (for example, a first CSI-RS resource or resource pair located in a first slot and a second CSI-RS resource or resource pair located in a subsequent slot may be considered concurrently active, as the UE may buffer CSI-RSs received via the first and second CSI-RS resources or resource pairs for TDCP measurements over time) . Without a way to limit the configuration of CSI-RS resources to a threshold quantity of concurrently active CSI-RS resources, the UE may be configured with too many concurrently active CSI-RS resources and may not be able to buffer a sufficient amount of the CSI-RSs to perform complete TDCP measurements for the concurrently active CSI-RS resources, or may fail to perform a TDCP measurement. Such failure to perform complete TDCP measurements, or failed TDCP measurements, may result in less accurate channel property reporting, inefficient expenditure of computational resources, and less reliable wireless communication, among other examples. Additionally, the UE may support beam management procedures based on performing other measurements during the same slot as the UE performs TDCP measurements. Separately managing or reporting buffering capabilities for beam management reporting and TDCP reporting, however, may result in increased UE memory requirements (due to respectively buffering TDCP-related and beam-management-related CSI-RS resources) , increased signaling overheard, or decreased effectiveness of beam management and / or TDCP measurements, other issues, or any combination.
[0028] Various aspects generally relate to TDCP measurements and reporting, beam management measurements and reporting, or both. In some aspects, a UE may report, to a network entity, a buffer capability associated with performing TDCP measurements, beam management measurements, or both. In some examples, the UE may report a threshold quantity of CSI-RS resources that may be concurrently active across one or more component carriers that the UE supports for TDCP measurements and reporting, or for both TDCP measurement and reporting and beam management measurements and reporting. The network entity may schedule reference resources (for example, CSI-RS resources) for TDCP measurements such that scheduled active CSI-RS resources within a given slot do not exceed the reported threshold quantity. The network entity may schedule one set of CSI-RS resources or multiple sets of CSI-RS resources, and the TDCP measurements may be performed across CSI-RS resources, such as across first and second CSI-RS resources of a single set of CSI-RS resources, or across CSI-RS resources of multiple sets of CSI-RS resources. In some examples, the UE may report a joint threshold quantity of concurrently active CSI-RS resources supported in one or more slots of a time duration, the joint threshold quantity indicating a total quantity of concurrently active CSI-RS resources for beam management measurements, TDCP measurements, or both. The threshold quantity reporting may be general across multiple frequency ranges (for example, FR1 and FR2) , or may be band-specific or frequency range-specific (for example, a first threshold quantity for FR1 and a second threshold quantity for FR2) .
[0029] Particular aspects of the subject matter described may be implemented to realize one or more of the following potential advantages. The techniques employed by the described communication devices may include more efficient scheduling of CSI-RS resources, more accurate TDCP reports, and decreased signaling overhead. For example, operations performed by the described communication devices may provide improvements to channel property measurement and reporting procedures by reducing or eliminating scheduling of CSI-RS resources for TDCP measurement that exceed the capability of the UE to buffer downlink signaling for the scheduled measurements. In some implementations, the operations performed by the described communication devices to ensure that the UE is scheduled with an appropriate quantity of CSI-RS resources in each slot, such that TDCP measurements can be effectively performed by the UE without exceeding a UE buffer capacity-preventing failed or incomplete TDCP measurement reporting. In some implementations, operations performed by the described communication devices may also support decreased overhead signaling, such as in examples in which the UE reports beam management and TDCP reporting buffer information together (for example, a single threshold quantity of concurrently active CSI-RS resources per slot for both beam management measurements and TDCP measurements) . In some implementations, operations performed by the described communication device may result in more reliable TDCP reporting, and / or improved reliability of wireless communication, and / or decreased system latency (for example, resulting from the decreased signaling overhead) , among other benefits.
[0030] Aspects of the disclosure are initially described in the context of wireless communication systems. Aspects of the disclosure are further illustrated by and described with reference to wireless communication systems, TDCP configuration schemes, and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to concurrent TDCP and beam management resource counting.
[0031] Figure 1 shows an example of a wireless communication system 100 that supports concurrent TDCP and beam management resource counting in accordance with one or more aspects of the present disclosure. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0032] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via one or more communication links 125 (for example, a radio frequency (RF) access link) . For example, a network entity 105 may support a coverage area 110 (for example, a geographic coverage area) over which the UEs 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .
[0033] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in Figure 1. The UEs 115 described herein may be capable of supporting communication with various types of devices, such as other UEs 115 or network entities 105, as shown in Figure 1.
[0034] As described herein, a node of the wireless communication system 100, which may be referred to as a network node, or a wireless node, may be a network entity 105 (for example, any network entity described herein) , a UE 115 (for example, any UE described herein) , a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE 115. As another example, a node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
[0035] In some examples, network entities 105 may communicate with the core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (for example, in accordance with an S1, N2, N3, or other interface protocol) . In some examples, network entities 105 may communicate with one another via a backhaul communication link 120 (for example, in accordance with an X2, Xn, or other interface protocol) either directly (for example, directly between network entities 105) or indirectly (for example, via a core network 130) . In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (for example, in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (for example, in accordance with a fronthaul interface protocol) , or any combination thereof. The backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (for example, an electrical link, an optical fiber link) , one or more wireless links (for example, a radio link, a wireless optical link) , among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
[0036] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (for example, a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB) , a 5G NB, a next-generation eNB (ng-eNB) , a Home NodeB, a Home eNodeB, or other suitable terminology) . In some examples, a network entity 105 (for example, a base station 140) may be implemented in an aggregated (for example, monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (for example, a single RAN node, such as a base station 140) .
[0037] In some examples, a network entity 105 may be implemented in a disaggregated architecture (for example, a disaggregated base station architecture, a disaggregated RAN architecture) , which may be configured to utilize a protocol stack that is physically or logically distributed among two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (for example, a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (for example, a cloud RAN (C-RAN) ) . For example, a network entity 105 may include one or more of a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN Intelligent Controller (RIC) 175 (for example, a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) 180 system, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (for example, separate physical locations) . In some examples, one or more network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (for example, a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0038] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (for example, network layer functions, protocol layer functions, baseband functions, RF functions, and any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (for example, layer 3 (L3) , layer 2 (L2) ) functionality and signaling (for example, Radio Resource Control (RRC) , service data adaption protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (for example, physical (PHY) layer) or L2 (for example, radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (for example, via one or more RUs 170) . In some examples, a functional split between a CU 160 and a DU 165, or between a DU 165 and an RU 170 may be within a protocol layer (for example, some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to one or more DUs 165 via a midhaul communication link 162 (for example, F1, F1-c, F1-u) , and a DU 165 may be connected to one or more RUs 170 via a fronthaul communication link 168 (for example, open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (for example, a channel) between layers of a protocol stack supported by respective network entities 105 that are in communication via such communication links.
[0039] In wireless communication systems (for example, wireless communication system 100) , infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (for example, to a core network 130) . In some examples, in an IAB network, one or more network entities 105 (for example, IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as a donor entity or an IAB donor. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a donor network entity 105 (for example, a donor base station 140) . The one or more donor network entities 105 (for example, IAB donors) may be in communication with one or more additional network entities 105 (for example, IAB nodes 104) via supported access and backhaul links (for example, backhaul communication links 120) . IAB nodes 104 may include an IAB mobile termination (IAB-MT) controlled (for example, scheduled) by DUs 165 of a coupled IAB donor. An IAB-MT may include an independent set of antennas for relay of communication with UEs 115, or may share the same antennas (for example, of an RU 170) of an IAB node 104 used for access via the DU 165 of the IAB node 104 (for example, referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB nodes 104 may include DUs 165 that support communication links with additional entities (for example, IAB nodes 104, UEs 115) within the relay chain or configuration of the access network (for example, downstream) . In such cases, one or more components of the disaggregated RAN architecture (for example, one or more IAB nodes 104 or components of IAB nodes 104) may be configured to operate according to the techniques described herein.
[0040] For instance, an access network (AN) or RAN may include communication between access nodes (for example, an IAB donor) , IAB nodes 104, and one or more UEs 115. The IAB donor may facilitate connection between the core network 130 and the AN (for example, via a wired or wireless connection to the core network 130) . That is, an IAB donor may refer to a RAN node with a wired or wireless connection to core network 130. The IAB donor may include a CU 160 and at least one DU 165 (for example, and RU 170) , in which case the CU 160 may communicate with the core network 130 via an interface (for example, a backhaul link) . IAB donor and IAB nodes 104 may communicate via an F1 interface according to a protocol that defines signaling messages (for example, an F1 AP protocol) . Additionally, or alternatively, the CU 160 may communicate with the core network via an interface, which may be an example of a portion of backhaul link, and may communicate with other CUs 160 (for example, a CU 160 associated with an alternative IAB donor) via an Xn-C interface, which may be an example of a portion of a backhaul link.
[0041] An IAB node 104 may refer to a RAN node that provides IAB functionality (for example, access for UEs 115, wireless self-backhauling capabilities) . A DU 165 may act as a distributed scheduling node towards child nodes associated with the IAB node 104, and the IAB-MT may act as a scheduled node towards parent nodes associated with the IAB node 104. That is, an IAB donor may be referred to as a parent node in communication with one or more child nodes (for example, an IAB donor may relay transmissions for UEs through one or more other IAB nodes 104) . Additionally, or alternatively, an IAB node 104 may also be referred to as a parent node or a child node to other IAB nodes 104, depending on the relay chain or configuration of the AN. Therefore, the IAB-MT entity of IAB nodes 104 may provide a Uu interface for a child IAB node 104 to receive signaling from a parent IAB node 104, and the DU interface (for example, DUs 165) may provide a Uu interface for a parent IAB node 104 to signal to a child IAB node 104 or UE 115.
[0042] For example, IAB node 104 may be referred to as a parent node that supports communication for a child IAB node, or referred to as a child IAB node associated with an IAB donor, or both. The IAB donor may include a CU 160 with a wired or wireless connection (for example, a backhaul communication link 120) to the core network 130 and may act as parent node to IAB nodes 104. For example, the DU 165 of IAB donor may relay transmissions to UEs 115 through IAB nodes 104, or may directly signal transmissions to a UE 115, or both. The CU 160 of IAB donor may signal communication link establishment via an F1 interface to IAB nodes 104, and the IAB nodes 104 may schedule transmissions (for example, transmissions to the UEs 115 relayed from the IAB donor) through the DUs 165. That is, data may be relayed to and from IAB nodes 104 via signaling via an NR Uu interface to MT of the IAB node 104. Communication with IAB node 104 may be scheduled by a DU 165 of IAB donor and communication with IAB node 104 may be scheduled by DU 165 of IAB node 104.
[0043] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support concurrent TDCP and beam management resource counting. For example, some operations described as being performed by a UE 115 or a network entity 105 (for example, a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (for example, IAB nodes 104, DUs 165, CUs 160, RUs 170, RIC 175, SMO 180) .
[0044] A UE 115 may include or may be referred to as a mobile device, a wireless communication device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.
[0045] The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in Figure 1.
[0046] The UEs 115 and the network entities 105 may wirelessly communicate with one another via one or more communication links 125 (for example, an access link) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a RF spectrum band (for example, a bandwidth part (BWP) ) that is operated according to one or more physical layer channels for a given radio access technology (for example, LTE, LTE-A, LTE-A Pro, NR) . Each physical layer channel may carry acquisition signaling (for example, synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communication system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (for example, entity, sub-entity) of a network entity 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network entity 105, may refer to any portion of a network entity 105 (for example, a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (for example, directly or via one or more other network entities 105) .
[0047] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (for example, an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute RF channel number (EARFCN) ) and may be identified according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode, in which case initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode, in which case a connection is anchored using a different carrier (for example, of the same or a different radio access technology) .
[0048] The communication links 125 shown in the wireless communication system 100 may include downlink transmissions (for example, forward link transmissions) from a network entity 105 to a UE 115, uplink transmissions (for example, return link transmissions) from a UE 115 to a network entity 105, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communication (for example, in an FDD mode) or may be configured to carry downlink and uplink communication (for example, in a TDD mode) .
[0049] A carrier may be associated with a particular bandwidth of the RF spectrum and, in some examples, the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular radio access technology (for example, 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communication system 100 (for example, the network entities 105, the UEs 115, or both) may have hardware configurations that support communication using a particular carrier bandwidth or may be configurable to support communication using one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include network entities 105 or UEs 115 that support concurrent communication using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating using portions (for example, a sub-band, a BWP) or all of a carrier bandwidth.
[0050] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (for example, using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may refer to resources of one symbol period (for example, a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (for example, the order of the modulation scheme, the coding rate of the modulation scheme, or both) , such that a relatively higher quantity of resource elements (for example, in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communication resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (for example, a spatial layer, a beam) , and the use of multiple spatial resources may increase the data rate or data integrity for communication with a UE 115.
[0051] One or more numerologies for a carrier may be supported, and a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communication for the UE 115 may be restricted to one or more active BWPs.
[0052] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts=1 / (Δfmax·Nf) seconds, for which Δfmax may represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communication resource may be organized according to radio frames each having a specified duration (for example, 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (for example, ranging from 0 to 1023) .
[0053] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (for example, in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (for example, depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communication systems 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (for example, Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
[0054] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (for example, in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (for example, a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (for example, in bursts of shortened TTIs (sTTIs) ) .
[0055] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (for example, a control resource set (CORESET) ) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (for example, CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (for example, control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to multiple UEs 115 and UE-specific search space sets for sending control information to a specific UE 115.
[0056] A network entity 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a network entity 105 (for example, using a carrier) and may be associated with an identifier for distinguishing neighboring cells (for example, a physical cell identifier (PCID) , a virtual cell identifier (VCID) , or others) . In some examples, a cell also may refer to a coverage area 110 or a portion of a coverage area 110 (for example, a sector) over which the logical communication entity operates. Such cells may range from smaller areas (for example, a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the network entity 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with coverage areas 110, among other examples.
[0057] A macro cell generally covers a relatively large geographic area (for example, several kilometers in radius) and may allow unrestricted access by the UEs 115 with service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a lower-powered network entity 105 (for example, a lower-powered base station 140) , as compared with a macro cell, and a small cell may operate using the same or different (for example, licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to the UEs 115 with service subscriptions with the network provider or may provide restricted access to the UEs 115 having an association with the small cell (for example, the UEs 115 in a closed subscriber group (CSG) , the UEs 115 associated with users in a home or office) . A network entity 105 may support one or multiple cells and may also support communication via the one or more cells using one or multiple component carriers.
[0058] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (for example, MTC, narrowband IoT (NB-IoT) , enhanced mobile broadband (eMBB) ) that may provide access for different types of devices.
[0059] In some examples, a network entity 105 (for example, a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, the overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.
[0060] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, network entities 105 (for example, base stations 140) may have similar frame timings, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, network entities 105 may have different frame timings, and transmissions from different network entities 105 may, in some examples, not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operations.
[0061] Some UEs 115, such as MTC or IoT devices, may be low cost or low complexity devices and may provide for automated communication between machines (for example, via Machine-to-Machine (M2M) communication) . M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a network entity 105 (for example, a base station 140) without human intervention. In some examples, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application program that uses the information or presents the information to humans interacting with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.
[0062] Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communication (for example, a mode that supports one-way communication via transmission or reception, but not transmission and reception concurrently) . In some examples, half-duplex communication may be performed at a reduced peak rate. Other power conservation techniques for the UEs 115 include entering a power saving deep sleep mode when not engaging in active communication, operating using a limited bandwidth (for example, according to narrowband communication) , or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type that is associated with a defined portion or range (for example, set of subcarriers or resource blocks (RBs) ) within a carrier, within a guard-band of a carrier, or outside of a carrier.
[0063] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC) . The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communication may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0064] In some examples, a UE 115 may be configured to support communicating directly with other UEs 115 via a device-to-device (D2D) communication link 135 (for example, in accordance with a peer-to-peer (P2P) , D2D, or sidelink protocol) . In some examples, one or more UEs 115 of a group that are performing D2D communication may be within the coverage area 110 of a network entity 105 (for example, a base station 140, an RU 170) , which may support aspects of such D2D communication being configured by (for example, scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communication may support a one-to-many (1: M) system in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communication. In some other examples, D2D communication may be carried out between the UEs 115 without an involvement of a network entity 105.
[0065] In some systems, a D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel, between vehicles (for example, UEs 115) . In some examples, vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. A vehicle may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relevant to a V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or with the network via one or more network nodes (for example, network entities 105, base stations 140, RUs 170) using vehicle-to-network (V2N) communication, or with both.
[0066] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (for example, a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (for example, a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (for example, base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.
[0067] The wireless communication system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communication using UHF waves may be associated with smaller antennas and shorter ranges (for example, less than 100 kilometers) compared to communication using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
[0068] The wireless communication system 100 may also operate using a super high frequency (SHF) region, which may be in the range of 3 GHz to 30 GHz, also known as the centimeter band, or using an extremely high frequency (EHF) region of the spectrum (for example, from 30 GHz to 300 GHz) , also known as the millimeter band. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communication between the UEs 115 and the network entities 105 (for example, base stations 140, RUs 170) , and EHF antennas of the respective devices may be smaller and more closely spaced than UHF antennas. In some examples, such techniques may facilitate using antenna arrays within a device. The propagation of EHF transmissions, however, may be subject to even greater attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions that use one or more different frequency regions, and designated use of bands across these frequency regions may differ by country or regulating body.
[0069] The wireless communication system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) radio access technology, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (for example, LAA) . Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0070] A network entity 105 (for example, a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communication with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.
[0071] The network entities 105 or the UEs 115 may use MIMO communication to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (for example, the same codeword) or different data streams (for example, different codewords) . Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , for which multiple spatial layers are transmitted to multiple devices.
[0072] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (for example, a network entity 105, a UE 115) to shape or steer an antenna beam (for example, a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (for example, with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
[0073] A network entity 105 or a UE 115 may use beam sweeping techniques as part of beamforming operations. For example, a network entity 105 (for example, a base station 140, an RU 170) may use multiple antennas or antenna arrays (for example, antenna panels) to conduct beamforming operations for directional communication with a UE 115. Some signals (for example, synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a network entity 105 multiple times along different directions. For example, the network entity 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions along different beam directions may be used to identify (for example, by a transmitting device, such as a network entity 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the network entity 105.
[0074] Some signals, such as data signals associated with a particular receiving device, may be transmitted by transmitting device (for example, a transmitting network entity 105, a transmitting UE 115) along a single beam direction (for example, a direction associated with the receiving device, such as a receiving network entity 105 or a receiving UE 115) . In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted along one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the network entity 105 along different directions and may report to the network entity 105 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.
[0075] In some examples, transmissions by a device (for example, by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (for example, from a network entity 105 to a UE 115) . The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entity 105 may transmit a reference signal (for example, a cell-specific reference signal (CRS) , a channel state information reference signal (CSI-RS) ) , which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (for example, a multi-panel type codebook, a linear combination type codebook, a port selection type codebook) . Although these techniques are described with reference to signals transmitted along one or more directions by a network entity 105 (for example, a base station 140, an RU 170) , a UE 115 may employ similar techniques for transmitting signals multiple times along different directions (for example, for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal along a single direction (for example, for transmitting data to a receiving device) .
[0076] A receiving device (for example, a UE 115) may perform reception operations in accordance with multiple receive configurations (for example, directional listening) when receiving various signals from a transmitting device (for example, a network entity 105) , such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may perform reception in accordance with multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (for example, different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (for example, when receiving a data signal) . The single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (for example, a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR) , or otherwise acceptable signal quality based on listening according to multiple beam directions) .
[0077] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communication at the bearer or PDCP layer may be IP-based. An RLC layer may perform packet segmentation and reassembly to communicate via logical channels. A MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer also may implement error detection techniques, error correction techniques, or both to support retransmissions to improve link efficiency. In the control plane, an RRC layer may provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a network entity 105 or a core network 130 supporting radio bearers for user plane data. A PHY layer may map transport channels to physical channels.
[0078] The UEs 115 and the network entities 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (for example, a communication link 125, a D2D communication link 135) . HARQ may include a combination of error detection (for example, using a cyclic redundancy check (CRC) ) , forward error correction (FEC) , and retransmission (for example, automatic repeat request (ARQ) ) . HARQ may improve throughput at the MAC layer in poor radio conditions (for example, low signal- to-noise conditions) . In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.
[0079] In wireless communication system 100, a UE 115 may be scheduled to perform various measurements, which may include TDCP measurements. The UE 115 may be configured with one or more sets of reference signal resources (for example, CSI-RSs) , and may perform the TDCP measurements over a duration (for example, in one or more CSI-RS resources across multiple time durations (for example, slots) ) . A delay related to the duration may include the time during which the TDCP measurements are to be performed (for example, a quantity of slots during which the UE 115 maintains buffered downlink signaling and performs the TDCP measurements via CSI-RS resources for a given TDCP report) . However, a size of a UE 115 buffer (for example, an amount of available storage for receive downlink signaling and measurements) may be limited, and the UE 115 may not be capable of supporting measurements across a group of CSI-RS resources (for example, may not be able to buffer the downlink signaling for an unlimited quantity of CSI-RS resources) . Without a way to limit the configuration of CSI-RS resources to a threshold quantity of concurrently active CSI-RS resources, the UE 115 may not effectively perform TDCP measurements, resulting in less accurate channel property reporting (e.g. TDCP for one or more component carriers not able to be measured and reported) , inefficient expenditure of computational resources, and less reliable wireless communication, among other examples. Additionally, the UE 115 may support beam management procedures based on performing measurements (for example, during the same slot as the UE 115 performs TDCP measurements) . Separately managing or reporting buffering capabilities for beam management reporting and TDCP reporting, however, may result in increased signaling overheard, and decreased effectiveness of beam management and / or TDCP measurements, or any combination.
[0080] The UE 115 may report a threshold quantity of concurrently active CSI-RS resources across one or more component carriers that the UE 115 supports for TDCP measurements and reporting. Active CSI-RS resources may refer to CSI-RS resources that are active for TDCP measurements (for example, a first CSI-RS resource or resource pair located in a first slot and a second CSI-RS resource or resource pair located in a subsequent slot may be considered concurrently active, as the UE 115 may buffer downlink signaling received via the first and second CSI-RS resources or resource pairs for TDCP measurements over time) . The network entity 105 may schedule reference resources (for example, CSI-RS resources) for TDCP measurements such that scheduled CSI-RS resources within a given slot do not exceed the reported threshold quantity. The network entity 105 may schedule one set of reference signal resources, or multiple sets of reference signal resources. The UE 115 and the network entity 105 may count reference signal resources as active during a given slot within a time delay (for example, a quantity of slots during which the UE 115 performs measurements over time, such as a delay between a first slot of a first set of reference signal resources and a first slot of a second set of reference signal resources) . A quantity of CSI-RS resources considered active may be defined by one or more rules (for example, two CSI-RS resources of a CSI-RS resource pair are considered active in a first slot, while in a second slot four CSI-RS resources including the CSI-RS resource pair in the first slot and two CSI-RS resources in the second slot may be considered active) . The rules may be based on a time delay (for example, a quantity of slots) for a given TDCP report. In some cases, the UE 115 may report a joint threshold quantity of concurrently active CSI-RS resources supported in one or more slots of a time delay, the joint threshold quantity indicating a total quantity of concurrently active CSI-RS resources for beam management measurements, TDCP measurements, or both. The threshold quantity reporting may be general across multiple frequency ranges (for example, FR1 and FR2) , or may be FR-specific (for example, a first threshold quantity for FR1 and a second threshold quantity for FR2) .
[0081] Figure 2 shows an example of a wireless communication system 200 that supports concurrent TDCP and beam management resource counting in accordance with one or more aspects of the present disclosure. The wireless communication system 200 may implement aspects of, or be implemented by aspects of, the wireless communication system 100. For example, the wireless communication system 200 may include a network entity 105-a, and a UE 115-a, which may be examples of corresponding devices described with reference to Figure 1.
[0082] The network entity 105-a and the UE 115-a may support various procedures for CSI reporting. In some examples, the wireless communication system 200 may support CSI reporting for high velocity or medium velocity UEs 115 by exploiting TD correlation and / or Doppler-domain information to assist downlink precoding (for example, targeting one or more frequency ranges, such as FR1) . In such examples, the UE 115-a may perform TDCP measurements via reference signal measurements (for example, CSI-RSs) for tracking (for example, tracking reference signals (TRSs) ) . For example, a highly mobile (for example, high velocity) UE 115-a may perform TDCP measurements via reference signal resources over time, and may report the TDCP measurements to the network entity 105-a. Use for TDCP measurements may include various procedures, such as codebook switching (for example, between type I codebooks and type II codebooks) , channel sounding switching (for example, between CSI feedback and SRS feedback) , changing or updating a periodicity of CSI or SRS signaling, changing DMRS time-density, among other examples. That is, the network entity 105-a may initiate one or more procedures or updates to wireless communication according to the TDCP measurements reported by the UE 115-a. The UE 115-a may perform the measurements over time, which may rely on a capability of the UE 115-a to maintain (for example, buffer) received downlink signaling over time (for example, across multiple time intervals, such as multiple symbols or multiple slots) .
[0083] The content of a TDCP measurement report may include time-correlation information (for example, which may be referred to as autocorrelation) . Autocorrelation may be defined as A (τ) , and calculated according to Equation (1) below:
[0084] where l and k, are time and frequency indices, respectively, and τ represents a time delay (for example, a lag) . The time delay may refer to an amount of time between a first reference signal resource (for example, via which TDCP measurements are performed) and a last reference signal resource (for example, via which TDCP measurements are performed) for a respective TDCP report (for example, a particular autocorrelation) . The UE 115-a may be configured by the network entity 105-a to report autocorrelation for various time delays (for example, lags) . For example, the UE 115-a may be configured to report TDCP measurements for a time delay of 1, 2, 3, or 4 slots. TDCP report (for example, in accordance with TRS measurements) may be configured with a parameter value Y, which may be set equal to 2, 3, or 4 (for example, 2 slots, 3 slots, or 4 slots) . In some examples, the TDCP reporting may be configured for a delay within a single reference signal set (for example, a time delay of four symbols, or one slot) . In some examples, the TDCP reporting may be configured for a time delay across slots (for example, a time delay of two slots, three slots, four slots, five slots, six slots, or ten slots, among other examples) . The UE 115-a may support periodic or aperiodic reporting (for example, TDCP reporting via a PUSCH) .
[0085] The network entity 105-a may configure the UE 115-a with one or more sets of reference signal resources (for example, TRS resources, or CSI-RS resources, among other examples) . For example, the network entity 105-a may transmit a control message 215 (for example, higher layer signaling) configuring one set of reference signal resources (for example, set 220-a) , or multiple sets of reference signal resources (for example, set 220-a and set 220-b) . Each set of reference signal resources may include one or more reference signal resources (for example, reference signal resources 205 for set 220-a, and reference signal resources 210 for set 220-b) . For instance, TRS resources may be configured as a set of four single-port CSI-RS resources in two consecutive slots, or a set of two single-port CSI-RS resources in one single slot (for example, via trs-info in an RRC message) . Periodic TRS may support specific periodicities (for example, 10, 20, 40, or 80 msec periodicity) , which may not support longer time delays (for example, of two or more slots) . For TDCP reporting, which may rely on longer time delays, a single set of reference signal resources may not provide a sufficient time delay for performing the TDCP measurements.
[0086] The UE 115-a may be configured with additional resource sets (CSI-RS resource sets) for TDCP reporting, such as a second set of reference signal resources (for example, set 220-b) . In some examples, a first set of reference signal resources may be referred to as a primary set of reference signal resources (for example, a TRS resource set) , and an additional set of reference signal resources may be referred to as a secondary or non-primary set of reference signal resources. An offset between the two sets of reference signal resources may be utilized to perform TDCP measurements across a larger time delay. For instance, set 220-a may support a delay 225-a (for example, four symbols) between a first reference signal resource 205 and a second reference signal resource 205 (for example, within a slot, such as slot 1) . This may limit the UE 115-a to TDCP measurements within a single slot, but not across slots. Similarly, measurements within a set of reference signal resources (for example, set 220-a) may support a delay 225-b (for example, one slot) , which may limit the UE 115-a to TDCP measurements across two slots, but the UE 115-a may not support TDCP measurements across more than two slots. However, in examples in which the UE 115-a is configured with multiple sets of reference signal resources (for example, set 220-a and set 220-b) , the UE 115-a may also support a delay 225-c (for example, five slots between a first reference signal resource 205 of the set 220-a, and a first reference signal resource 210 of the set 220-b) . In some examples, configuration of multiple sets 220 for TDCP measurements may leverage one or more configured sets of reference signal resources, such as a TRS set.
[0087] In some examples, one additional set of reference signal resources (for example, set 220-b) may have a longer periodicity than a first set of reference signal resources (for example, set 220-b) . For instance, the set 220-a may be a TRS set, and may have a smaller periodicity than the set 220-b. In such examples, the periodicity of set 220-b may be an integer multiple of the periodicity of the set 220-a (for example, because TDCP reporting may not correspond to as frequency updates as TRS reporting) . In some examples, TDCP reporting may be performed according to any combination or quantity of reference signal resource sets (for example, two sets, three sets, four sets, or more) . For instance, a first set of reference signal resources (for example, a TRS set) may have a periodicity of 10 ms, and a second set of reference signal resources may have a periodicity of 40 ms. In some examples, the reference signal resource sets may include varying quantities of reference signal resources (for example, the first reference signal resource set may include a resource pair per period, while the second reference signal resource set may include a single reference signal resource per period, or a pair of reference signal resource per period, or two pairs of reference signal resources per period, among other examples) . Reference signal resource sets may be defined as TRS sets, or may be defined in terms of parameters, such as port, type, frequency density, or the like (for example, a single-port CSI-RS resource with frequency density equal to a quantity of REs per RB) . In some examples, reference signal resources (for example, set 220-a and set 220-b) may be configured for TDCP reporting according to a quasi-co-location (QCL) relationship, such that the set 220-a and the set 220-b are QCL (for example, QCL-typeA, QCL-typeD) , which may support derivation of autocorrelation (for example, TDCP measurements across time according to the QCL relationship) .
[0088] The UE 115-a many perform TDCP measurements (for example, via reference signal resources of one or more sets 220) , and may generate a TDCP report 230. For TDCP reporting (for example, for autocorrelation reporting) , the UE 115-a may buffer raw demodulation data of one or more reference signal resources (for example, CSI-RS resources) over a long duration, especially for cross-set delays (for example, the delay 225-c, which may be greater than two slots) . Raw demodulation buffering may consume a great amount of memory. A buffering capacity (for example, budget) at the UE 115-a may depend on a threshold concurrent buffer utilized for TDCP measurement. For example, the UE 115-a may have a threshold amount of memory available, but may need to buffer raw demodulation data for reference signals received during slot 1 (for example, via reference signal resources 205 of the set 220-a) at least until reception of reference signals received during slot 6 (for example, via reference signal resources 210 of the set 220-b) . In examples in which a quantity of raw demodulation data exceeds the capability of the threshold amount of memory, then the UE 115-a may not successfully perform the TDCP measurements, resulting in an incomplete or inaccurate TDCP reporting.
[0089] As described herein, an active reference signal resource may refer to a reference signal resource for which the UE 115-a is buffering raw data for TDCP reporting. A quantity of concurrently active reference signal resources for any given slot (for example, which may include previous reference signal resources in a previous slot because raw data received via the previous reference signal resources is still buffering at the UE 115-a) may be defined (for example, according to one or more configured or standardized rules) to ensure that the UE 115-a is not expected to buffer more raw data over time than the UE 115-a is capable of buffering. For example, the UE 115-a receives reference signals via the reference signal resources 205 in slot 1, and is configured to perform TDCP reporting across set 220-a and set 220-b. In such examples, the UE 115-a may be able to successfully perform the TDCP reporting in examples in which the UE 115-a is capable of supporting up to four active reference signal resources for each of slots 1, 2, 3, 4, 5, and 6. That is, the UE 115-a may be capable of maintaining up to four active reference signal resources for each slot corresponding to delay 225-c, and may buffer the raw demodulation data corresponding to reception of the reference signaling even during intermediate slots 2, 3, 4, and 5 (for example, may be buffering data from slot 1 at least until reception of reference signals via reference signal resources 210 during slot 6) .
[0090] In some examples, the UE 115-a may share its buffering capacity across various procedures. For example, the UE 115-a may also generate beam forming reports according to measurements over time (for example, layer 1 reference signal receive power (RSRP) measurements, L1 signal to interreference and noise ratio (L1-SINR) measurements, beam failure detection (BFD) measurements, or radio link monitoring (RLM) measurements) . The UE 115-a may report beam forming capability information, which may indicate a threshold quantity of beam management related CSI-RS resources within a given slot (for example, across CCs, within or across a frequency range or multiple frequency ranges, such as FR1, and FR2) , which may limit buffering requirements across CCs. However, reporting such beam management capability information may increase signaling overhead.
[0091] Techniques described herein support signaling and rules for defining and reporting threshold quantities of concurrently active reference signal resources that the UE 115-a supports (for example, per slot of a given delay 225) , which may improve the quality and accuracy of TDCP reporting. Techniques described herein further support signaling and rules for reporting a total concurrent buffer threshold for beam management and TDCP related reference signal resources (for example, and sharing of the buffer available at the UE 115-a across beam management and TDCP reporting) .
[0092] The UE 115-a may transmit capability information 235. The capability information 235 may indicate a threshold quantity of concurrently active reference signal (for example, CSI-RS) resources (for example, across CCs) for TDCP reporting (for example, TRP-based TDCP reporting) . The UE 115-a may then not expect to have more active CSI-RS resources scheduled (for example, for any slot of a delay 225) than reported in the capability information 235. Time durations (for example, slots) and quantities of CSI-RS resources associated with a set of CSI-RS resources or a set pair may be counted active according to the delay configured for the given set (for example, a one slot delay for a single set 220-a) or set pair (for example, a delay of two or more slot for multiple sets such as set 220-a and set 220-b) . For example, the network entity 105-a may refrain from scheduling more reference signal resources in any given slot or in a set 220 or across multiple sets 220 than the UE 115-a supports, as indicated in the capability information 235. In some examples, even in examples in which more CSI-RS resources are scheduled than the UE 115-a supports, the UE 115-a may not be configured to perform TDCP reporting in examples in which active CSI-RS resources would exceed the reported threshold quantity.
[0093] Reference signal resources (for example, CSI-RS resources) may be considered active according to one or more rules. For example, a quantity of CSI-RS resources considered active in any given slot may be defined according to a parameter value X, in which X may indicate a quantity of resource-pairs associated with a given set (for example, for a first set of reference signal resources, X may be set equal to 1, 2, or 4) . X may also be the total number of CSI-RS resources within a set other than the first set (for example, the TRS) For the set 220-a, X=2 (for example, two reference signal resources 205 in slot 1. In some examples, there may be two reference signal resources 210 in total in set 220-b) . The configuration of any set 220 may indicate a value for X. In some examples (for example, according to a first rule) , a quantity of reference signal resources considered active in a given slot may be defined as X for a first delay slot (for example, a first slot of a given delay 225) and maybe defined as 2·X for the last slot (for example, the delay 225 plus 1) . For instance, for X=2 and a configured TDCP report with a delay 225-b, two reference signal resources may be considered active during slot 1, and four reference signal resources may be considered active during slot 2. Similarly, for X=2 and a configured TDCP report with a delay 225-c, two reference signal resources (for example, two reference signal resources 205) may be considered active during slot 1, and four reference signal resources may be considered active during slot 6 (for example, two reference signal resources 205 from slot 1 and two reference signal resources 210 from slot 6) .
[0094] In some examples (for example, according to a second rule) , for each slot of a delay 225 and the delay plus 1 (for example, slots 1–6 for delay 225-c of five slots) , the quantity of reference signal resources counted as active may be equal to X. Such a rule may be supported in which the last slot (for example, slot 2 for a delay 225-b, slot 6 for a delay 225-c) may have an in-place TDCP calculation operation utilizing previously buffered data, and no additional memory may be assumed or utilized by the UE 115-a. In such examples, for X=2 and a configured TDCP report with a delay 225-b, two reference signal resources may be considered active for slot 1 and for slot 2. For X=2 and a configured TDCP report with a delay 225-c, two reference signal resources may be considered active for each of slots 1–6.
[0095] In some examples (for example, according to a third rule) , for each slot of a delay 225 and the delay plus 1 (for example, slots 1–6 for delay 225-c of five slots) , the quantity of reference signal resources counted as active may be counted as 2·X. In such examples, for X=2 and a configured TDCP report with a delay 225-b, four reference signal resources may be considered active for slot 1 and for slot 2. For X=2 and a configured TDCP report with a delay 225-c, four reference signal resources may be considered active for each of slots 1–6.
[0096] In some examples, for delay 225-a (for example, a four symbol delay) , reference signal resources considered active may be counted as two (for example, or X) for any TDCP reporting associated with one or two slots, or may be counted as one for any TDCP reporting associated with one or two slots.
[0097] In some examples, X may be per-report configured. One report may include a quantity of autocorrelations (for example, Y set equal to 1, 2, 3, or 4 autocorrelations) . X may be configured and set equal to a quantity of reference signal resources or reference signal resource pairs per set for one or more reference signal resource sets (for example, set 220-a or set 220-b) . In some examples, X may be set equal to a total quantity of reference signal resources per slot of a second set of reference signal resources (for example, set 220-b) . In some examples, X may be implicitly determined by the UE 115-a by a common quantity of reference signal resources per set for one or more reference signal resources other than a first (for example, TRS) set of reference signal resource sets. For example, set 220-a may be considered a first or primary set of reference signal resources, such as a TRS configuration, and set 220-b may be considered a second or secondary set of reference signal resources for a given TDCP report. In such examples, X may be set equal to a quantity of reference signal resources per set for the second or secondary set of reference signal resources (for example, X=4 for set 220-b) .
[0098] In such examples (for example, according to a first rule, and in which X is defined according to the second set 220-b) , a quantity of reference signal resources considered active in a given slot may be defined to be up to X for at least a first slot of the delay 225, and up to 2·X for one or more intermediate or the last slot of the delay 225. For instance, for X=4 and a delay 225-c, two reference signal resources may be considered active in slot 1, four reference signal resources may be considered active in each of slots 2 trough 5, six reference signal resources may be considered active in slot 6, and four reference signal resources may be considered active in slot 7. In some examples, an additional or secondary set of reference signal resources for TDCP reporting may have a different value for X, such as X=1 (for example, although not illustrated with reference to Figure 2, the set 220-b could include only a single reference signal resource 210, which could be located in slot 6) . For such examples, in which X=1, and for a configured a delay 225-c, one reference signal resource may be considered active for slot 1, and two reference signal resources may be considered active for slot 6 (for example, the last slot of the delay 225-c) . In such examples, the second reference signal resource 205 in slot 1, and both reference signal resources 205 in slot 2, may not be considered active because TDCP measurements may involve a first reference signal resource 205 of the set 220-a, and the only available reference signal resource 210 in set 220-b (for example, the additional reference signal resources 205 may not be associated with the TDCP report) .
[0099] In some examples (for example, according to a second rule and in which X is defined in accordance with the second set 220-b) , a quantity of reference signal resources considered active in a given slot may be defined to be up to X for each slot. For example, for X=4 and a delay 225-c, two reference signal resources may be considered active in slot 1, four reference signal resources may be considered active in each of slots 2–6, and two reference signal resources may be considered active in slot 7. In some examples, an additional or secondary set of reference signal resources for TDCP reporting may have a different value for X, such as X=1 (for example, although not illustrated with reference to Figure 2, the set 220-b could include only a single reference signal resource 210, which could be located in slot 6) . For such examples, in which X=1, and for a configured a delay 225-c, one reference signal resource may be considered active in each of slots 1–6.
[0100] In some examples (for example, according to a third rule and in which X is defined in accordance with the second set 220-b) , a quantity of reference signal resources considered active in a given slot may be defined to be up to 2·X for each slot. For example, for X=4 and a delay 225-c, four reference signal resources may be considered active in slot 1, eight reference signal resources may be considered active in each of slots 2–6, and four reference signal resources may be considered active in slot 7. In some examples, an additional or secondary set of reference signal resources for TDCP reporting may have a different value for X, such as X=1 (for example, although not illustrated with reference to Figure 2, the set 220-b could include only a single reference signal resource 210, which could be located in slot 6) . For such examples, in which X=1, and for a configured a delay 225-c, two reference signal resources may be considered active in each of slots 1–6.
[0101] As described herein, the UE 115-a may transmit capability information 235, indicating a threshold quantity of supported concurrently active reference signal resources (for example, across CCs) that the UE 115-a supports for TRS-based TDCP reporting. The UE 115-a may not expect to be configured with more active reference signal resources in any slot (for example, of a given delay) than reported in the capability information 235. The network entity 105-a may refrain from configuring sets 220 to exceed the threshold quantity of supported concurrently active reference signal resources, or may not configure the TDCP reporting to rely on a quantity of concurrently active reference signal resources in any slot for a TDCP report that exceeds the threshold quantity o supported concurrently active reference signal resources. The UE 115-a and the network entity 105-a may count reference signal resources as active according to one or more rules or conditions (for example, as described with reference to Figure 2) .
[0102] In some examples, the capability information 235 may indicate a joint threshold quantity of concurrently active reference signal resources (for example, across one or more CCs) for TDCP reporting (for example, TRS-based TDCP reporting) and beam management related reporting. The UE 115-a may not expect to have more active reference signal resources (for example, CSI-RS resources) for beam management reporting or TDCP reporting in any slot. The threshold quantity of concurrently active reference signal resources may apply to active BWPs, or may be a per-band report, or a per-band-combination report. The threshold quantity of concurrently active reference signal resources may apply to supported bands (for example, in examples in which the threshold quantity is greater than 0) , and the value of the threshold quantity may be band-common for a same frequency range (for example, a common value for all bands in a given frequency range, such as FR1, and a common value for all bands in another frequency range (for example, FR2) . In some examples, for the joint threshold quantity of concurrently active reference signal resources for TDCP reporting and beam management related reporting in any slot, a reference slot duration may be a shortest available or supported slot (for example, a largest subcarrier spacing) supported by the UE 115-a for a frequency range –in a shorter slot naturally means in a longer slot. Beam management related reporting may include one or more of beam management reporting, pathloss measurements reporting, beam failure detection (BFD) reporting, radio link monitoring (RLM) reporting, and new beam identification. The UE 115-a may then perform both beam management related measurements and TDCP measurements using reference signals received via the reference signal resources, and may buffer received reference signals for both types of reporting (for example, sharing a buffer across beam management data and measurements, and TDCP data and measurements) .
[0103] The UE 115-a may report TDCP reporting alone, or in combination with beam management related reporting, for one or more frequency ranges (for example, for FR1 and FR2) . In some examples, the UE 115-a may indicate (for example, in the capability information 235) , a single threshold quantity of concurrently active reference signal resources per slot supported by the UE 115-a across FR1 and FR2. In some examples, the UE 115-a may report two threshold quantities of concurrently active reference signal resources per slot (for example, denoted as M1 for FR1 and M2 for FR2) . In some examples, a single threshold quantity of concurrently active reference signal resources per slot supported by the UE 115-a may be defined across FR1 and FR2 as the greater of M1 and M2. In some examples, a single threshold quantity of concurrently active reference signal resources per slot supported by the UE 115-a may be defined across FR1 and FR2 as the greater of M1 and Z·M2, in which Z is defined as a ratio between a smallest SCS of FR1 and FR2 supported by the UE 115-a, or the ratio between the largest SCSO of FR1 and FR2 supported by the UE 115-a.
[0104] In some examples, the network entity 105-a may configure TDCP reporting, and may indicate timing or periodicity of TDCP reporting and measurements, as described in greater detail with reference to Figure 3.
[0105] Figure 3 shows an example of a TDCP configuration scheme 300 that supports concurrent TDCP and beam management resource counting in accordance with one or more aspects of the present disclosure. The TDCP configuration scheme 300 may implement, or may be implemented by, aspects of the wireless communication system 100, and the wireless communication system 200. For example, a UE 115 and a network entity 105 may perform T DCP reporting according to the TDCP configuration scheme 300, and the UE 115 and the network entity 105 may be examples of corresponding devices described with reference to Figures 1–2.
[0106] The network entity 105 may configure the UE 115 with a TDCP measurement periodicity (for example, which may be indicated by a parameter value such as Pmeas. In some examples, Pmeas may correspond to a periodicity of a first or primary set of reference signal resources (for example, set 220-a) . However, in some examples, Pmeas may be different than a TRS periodicity of the first or primary set of reference signal resources (for example, may be different than a first periodicity Pset1 corresponding to the first set of reference signal resources) . Pmeas may be per-report configured. Pmeas may be equal to a periodicity of CSI-RS resources of other sets (for example, sets K-1) , such as a secondary or additional set of reference signal resources (for example, a set 220-b) . In some examples, Pmeas may be explicitly indicated via higher layer signaling. In some examples, Pmeas may be implicitly determined by a common periodicity of the secondary set (and / or other set (s) than the first set) of reference signal resources (for example, other than the first or primary set of reference signal resources) . For example, the configuration of a given TDCP report may indicate a set of reference signal resources, and a periodicity of the other set may be set equal to Pmeas.
[0107] The network entity 105 may transmit a configuration message 305 (for example, such as a control message 215. The configuration message 305 may be a CSI-MeasConfig message. The CSI-MeasConfig may include a CSI-AperiodicTriggerStateList, which may define a reporting configuration (for example, CSI-REportConfig) , reference signal resource configuration (for example, CSI-Resourceconfig) , one or more reference signal resource sets (for example, NZP-CSI-RS-ResourceSet) , and one or more reference signal resources (for example, NZP-CSI-RS-Resource) . For example, the CSI-AperiodicTriggerStateList may include a CSI report configuration information indicating configuration of CSI resources. The configuration of CSI resources may define one or more reference signal resource sets (for example, such as set 1, which may be an example of set 220-a, and set 2, which may be an example of set 220-b) . Each reference signal resource set may include one or more reference signal resources (for example, set 1 may include four reference signal resources set 2 may include 1, 2, or 4 reference signal resources, among other examples) .
[0108] The configuration message 305 may include measurement information 310. In some examples, measurement information 310 may correspond to or be included in the CSI-ReportConfig. The measurement information 310 may include a report quantity (for example, Y) , a TDCP delay value (for example, 4 symbols, 1 slot, 2 slots, 5 slots, among other examples) , a value of X (for example, as described with reference to Figure 2) , and an indication of Pmeas. In some examples, Pmeas may be explicitly configured via the measurement information. In some examples, Pmeas may be implicitly determined according to a secondary set (for example, a periodicity of set 2) . The configuration message 305 may include resource type information 315 (for example, which may indicate a resource type, such as periodic or aperiodic) . The configuration message 305 may include aperiodic triggering offset information 320 (for example, aperiodicTriggeringOffset) , which may indicate TRS information (for example, for set 1) . In some examples, the configuration message 305 may include periodicity and offset information 325 (for example, periodicityAndOffset) which may be associated with the reference signal resources. In some examples, the implicit determination of Pmeas may be defined in accordance with the periodicity information indicated in the aperiodic triggering offset information 320, or on the periodicity information included in the periodicity and offset information 325 (for example, for the reference signal resources of a secondary set of reference signal resources, such as set 2.
[0109] Figure 4 shows an example of a process flow 400 that supports concurrent TDCP and beam management resource counting in accordance with one or more aspects of the present disclosure. The process flow 400 may implement, or be implemented by, aspects of the wireless communication system 100, the wireless communication system 200, the TDCP configuration scheme 300, or any combination thereof. For example, the process flow 400 may include a UE 115-b and a network entity 105-b, which may be examples of corresponding devices described with reference to Figures 1–3.
[0110] At 405, the UE 115-b may transmit (for example, to the network entity 105-b) capability information. The capability information may indicate a threshold quantity of concurrently active reference signal resources supported by the UE for TDCP measurements and reporting across one or more CCs for each time duration (for example, slot) of a set of time durations (for example, a time delay, such as a delay 225) . The capability information may be an example of capability information 235. In some examples, the capability information may include an indication of a joint threshold quantity of reference signal resources supported by the UE 115-b in each time duration (for example, corresponding to a delay) for both beam management measurements, and TDCP reporting. The joint threshold quantity may be greater than or equal to a threshold quantity of concurrently active reference signals for TDCP reporting. In some examples, the threshold quantity of concurrently active reference signal resources supported by the UE 115-b may indicate a single threshold quantity for multiple frequency bands (for example, FR1 and FR2) , or may indicate separate threshold quantities for each frequency band.
[0111] At 410, the UE 115-b may receive (for example, from the network entity 105-b) , control signaling. The control signaling may indicate one or more sets of reference signal resources. The one or more sets of reference signal resources may include a single set of reference signal resources (for example, a TRS set, such as a primary set or set 1) , or may include multiple sets of reference signal resources (for example, a first or primary set of reference signal resources, and one or more additional or secondary sets of reference signal resources) . At 415, the UE 115-b may receive (for example, from the network entity 105-b) one or more reference signals via the one or more sets of reference signal resources. In some examples, the UE 115-b may receive (for example, via the control signaling at 410) an indication of a measurement periodicity for performing the TDCP measurements. In such examples, at 420, the UE 115-b may perform the TDCP measurements according to the periodicity. In some examples (for example, in examples in which the UE 115-b reports a joint threshold quantity at 405) , the UE 115-b may receive control signaling indicating a first subset of reference signal resources of a shared pool of reference signal resources for beam management, and a second subset of reference signal resources of the shared pool of reference signal resources for TDCP measurements and reporting.
[0112] In some examples, the UE 115-b and the network entity 105 may determine (for example, count) reference signal resources as concurrently active (for example, for a given slot) based on one or more rules, or conditions. For example, a first quantity of reference signal resources corresponding to an initial time duration may be counted as concurrently active, and a second quantity of reference signal resources corresponding to a final time duration may be counted as concurrently active. The second quantity (for example, 2·X) of concurrently active reference signal resources may be greater than the first quantity (for example, X) of concurrently active reference signal resources. In some examples, a same quantity of reference signal resources (for example, X or 2·X) are counted concurrently active in each time duration. In some examples, the threshold quantity of concurrently active reference signal resources supported by the UE 115-b.
[0113] At 420, the UE 115-b may perform TDCP measurements on the one or more reference signals in accordance with having received the one or more reference signals at 415. In accordance with the one or more sets of reference signal resources, a quantity of active reference signal resources in each time duration (for example, slot) of the multiple slots (for example, the delay plus one slot) may be less than or equal to the threshold quantity of concurrently active reference signal resources.
[0114] At 425, the UE 115-b may transmit TDCP information (for example, a TDCP report, such as the report 230) .
