62/410,258 filed October 19, 2016, entitled "MULTI-CARRIER QCL FOR ANTENNA PORTS IN NR", the contents of which are herein incorporated by reference in their entirety.

FIELD

[0002] The present disclosure relates to wireless technology, and more specifically to techniques for facilitating multi-carrier QCL (Quasi Co-Location) for antenna ports in 5G (3GPP (Third Generation Partnership Project) Fifth Generation) NR (New Radio).

BACKGROUND

[0003] In LTE (Long Term Evolution), the antenna port is used for transmission of a physical channel or signal, where an antenna port is defined such that the channel over which a symbol on the antenna port (AP) is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed. Different antenna ports can correspond to different reference signals, which can be used for channel estimation and processing of the physical channel transmitted on the same antenna ports. The antenna ports of the same or different reference signals can be quasi co- located. Two antenna ports are said to be quasi co-located (QCL) if the large-scale properties of the channel over which a symbol on one antenna port is conveyed can be inferred from the channel over which a symbol on the other antenna port is conveyed.

[0004] The large-scale properties for LTE can comprise one or more of: (a) Average delay (first-order statistics for a time property of the channel), (b) Delay spread (second- order statistics for the time property of the channel), (c) Doppler shift (first-order statistics for a frequency property of the channel), (d) Doppler spread (second-order statistics for the frequency property of the channel), or (e) Average gain (first-order statistics for an amplitude property of the channel).

[0005] The large-scale properties estimated on antenna port(s) of reference signal(s) can be used to parametrize a channel estimator and/or compensate possible time and frequency errors when deriving CSI feedback or when performing demodulation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The present disclosure will now be described with reference to the attached drawing figures, wherein like reference numerals are used to refer to like elements throughout, and wherein the illustrated structures and devices are not necessarily drawn to scale. As utilized herein, terms "component," "system," "interface," and the like are intended to refer to a computer-related entity, hardware, software (e.g., in execution), and/or firmware. For example, a component can be a processor (e.g., a microprocessor, a controller, or other processing device), a process running on a processor, a controller, an object, an executable, a program, a storage device, a computer, a tablet PC and/or a user equipment (e.g., mobile phone, etc.) with a processing device. By way of illustration, an application running on a server and the server can also be a component. One or more components can reside within a process, and a component can be localized on one computer and/or distributed between two or more computers. A set of elements or a set of other components can be described herein, in which the term "set" can be interpreted as "one or more."

[0017] Further, these components can execute from various computer readable storage media having various data structures stored thereon such as with a module, for example. The components can communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network, such as, the Internet, a local area network, a wide area network, or similar network with other systems via the signal).

[0018] As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry, in which the electric or electronic circuitry can be operated by a software application or a firmware application executed by one or more processors. The one or more processors can be internal or external to the apparatus and can execute at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts; the electronic components can include one or more processors therein to execute software and/or firmware that confer(s), at least in part, the functionality of the electronic components.

[0019] Use of the word exemplary is intended to present concepts in a concrete fashion. As used in this application, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or". That is, unless specified otherwise, or clear from context, "X employs A or B" is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then "X employs A or B" is satisfied under any of the foregoing instances. In addition, the articles "a" and "an" as used in this application and the appended claims should generally be construed to mean "one or more" unless specified otherwise or clear from context to be directed to a singular form. Furthermore, to the extent that the terms "including", "includes", "having", "has", "with", or variants thereof are used in either the detailed description and the claims, such terms are intended to be inclusive in a manner similar to the term "comprising." Additionally, in situations wherein one or more numbered items are discussed (e.g., a "first X", a "second X", etc.), in general the one or more numbered items may be distinct or they may be the same, although in some situations the context may indicate that they are distinct or that they are the same.

[0020] As used herein, the term "circuitry" may refer to, be part of, or include an Application Specific Integrated Circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group), and/or memory (shared, dedicated, or group) that execute one or more software or firmware programs, a combinational logic circuit, and/or other suitable hardware components that provide the described functionality. In some embodiments, the circuitry may be implemented in, or functions associated with the circuitry may be implemented by, one or more software or firmware modules. In some embodiments, circuitry may include logic, at least partially operable in hardware.

[0021] Embodiments described herein may be implemented into a system using any suitably configured hardware and/or software. FIG. 1 illustrates an architecture of a system 1 00 of a network in accordance with some embodiments. The system 100 is shown to include a user equipment (UE) 101 and a UE 102. The UEs 101 and 102 are illustrated as smartphones (e.g., handheld touchscreen mobile computing devices connectable to one or more cellular networks), but may also comprise any mobile or non-mobile computing device, such as Personal Data Assistants (PDAs), pagers, laptop computers, desktop computers, wireless handsets, or any computing device including a wireless communications interface.

[0022] In some embodiments, any of the UEs 101 and 102 can comprise an Internet of Things (loT) UE, which can comprise a network access layer designed for low-power loT applications utilizing short-lived UE connections. An loT UE can utilize technologies such as machine-to-machine (M2M) or machine-type communications (MTC) for exchanging data with an MTC server or device via a public land mobile network (PLMN), Proximity-Based Service (ProSe) or device-to-device (D2D) communication, sensor networks, or loT networks. The M2M or MTC exchange of data may be a machine-initiated exchange of data. An loT network describes interconnecting loT UEs, which may include uniquely identifiable embedded computing devices (within the Internet infrastructure), with short-lived connections. The loT UEs may execute background applications (e.g., keep-alive messages, status updates, etc.) to facilitate the connections of the loT network.

[0023] The UEs 101 and 102 may be configured to connect, e.g., communicatively couple, with a radio access network (RAN) 1 10— the RAN 1 10 may be, for example, an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN), a NextGen RAN (NG RAN), or some other type of RAN. The UEs 101 and 102 utilize connections 103 and 104, respectively, each of which comprises a physical communications interface or layer (discussed in further detail below); in this example, the connections 103 and 104 are illustrated as an air interface to enable communicative coupling, and can be consistent with cellular communications protocols, such as a Global System for Mobile Communications (GSM) protocol, a code-division multiple access (CDMA) network protocol, a Push-to-Talk (PTT) protocol, a PTT over Cellular (POC) protocol, a Universal Mobile Telecommunications System (UMTS) protocol, a 3GPP Long Term Evolution (LTE) protocol, a fifth generation (5G) protocol, a New Radio (NR) protocol, and the like.

[0024] In this embodiment, the UEs 101 and 1 02 may further directly exchange communication data via a ProSe interface 105. The ProSe interface 105 may

alternatively be referred to as a sidelink interface comprising one or more logical channels, including but not limited to a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel (PSSCH), a Physical Sidelink Discovery Channel (PSDCH), and a Physical Sidelink Broadcast Channel (PSBCH).

[0025] The UE 102 is shown to be configured to access an access point (AP) 106 via connection 107. The connection 107 can comprise a local wireless connection, such as a connection consistent with any IEEE 802.1 1 protocol, wherein the AP 106 would comprise a wireless fidelity (WiFi®) router. In this example, the AP 1 06 is shown to be connected to the Internet without connecting to the core network of the wireless system (described in further detail below).

[0026] The RAN 1 1 0 can include one or more access nodes that enable the connections 1 03 and 104. These access nodes (ANs) can be referred to as base stations (BSs), NodeBs, evolved NodeBs (eNBs), next Generation NodeBs (gNB), RAN nodes, and so forth, and can comprise ground stations (e.g., terrestrial access points) or satellite stations providing coverage within a geographic area (e.g., a cell). The RAN 1 1 0 may include one or more RAN nodes for providing macrocells, e.g., macro RAN node 1 1 1 , and one or more RAN nodes for providing femtocells or picocells (e.g., cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells), e.g., low power (LP) RAN node 1 12.

[0027] Any of the RAN nodes 1 1 1 and 1 12 can terminate the air interface protocol and can be the first point of contact for the UEs 101 and 102. In some embodiments, any of the RAN nodes 1 1 1 and 1 12 can fulfill various logical functions for the RAN 1 1 0 including, but not limited to, radio network controller (RNC) functions such as radio bearer management, uplink and downlink dynamic radio resource management and data packet scheduling, and mobility management.

[0028] In accordance with some embodiments, the UEs 101 and 102 can be configured to communicate using Orthogonal Frequency-Division Multiplexing (OFDM) communication signals with each other or with any of the RAN nodes 1 1 1 and 1 1 2 over a multicarrier communication channel in accordance various communication techniques, such as, but not limited to, an Orthogonal Frequency-Division Multiple Access (OFDMA) communication technique (e.g., for downlink communications) or a Single Carrier Frequency Division Multiple Access (SC-FDMA) communication technique (e.g., for uplink and ProSe or sidelink communications), although the scope of the embodiments is not limited in this respect. The OFDM signals can comprise a plurality of orthogonal subcarriers.

[0029] In some embodiments, a downlink resource grid can be used for downlink transmissions from any of the RAN nodes 1 1 1 and 1 12 to the UEs 101 and 1 02, while uplink transmissions can utilize similar techniques. The grid can be a time-frequency grid, called a resource grid or time-frequency resource grid, which is the physical resource in the downlink in each slot. Such a time-frequency plane representation is a common practice for OFDM systems, which makes it intuitive for radio resource allocation. Each column and each row of the resource grid corresponds to one OFDM symbol and one OFDM subcarrier, respectively. The duration of the resource grid in the time domain corresponds to one slot in a radio frame. The smallest time-frequency unit in a resource grid is denoted as a resource element. Each resource grid comprises a number of resource blocks, which describe the mapping of certain physical channels to resource elements. Each resource block comprises a collection of resource elements; in the frequency domain, this may represent the smallest quantity of resources that currently can be allocated. There are several different physical downlink channels that are conveyed using such resource blocks.

[0030] The physical downlink shared channel (PDSCH) may carry user data and higher-layer signaling to the UEs 101 and 102. The physical downlink control channel (PDCCH) may carry information about the transport format and resource allocations related to the PDSCH channel, among other things. It may also inform the UEs 101 and 102 about the transport format, resource allocation, and H-ARQ (Hybrid Automatic Repeat Request) information related to the uplink shared channel. Typically, downlink scheduling (assigning control and shared channel resource blocks to the UE 102 within a cell) may be performed at any of the RAN nodes 1 1 1 and 1 12 based on channel quality information fed back from any of the UEs 101 and 102. The downlink resource assignment information may be sent on the PDCCH used for (e.g., assigned to) each of the UEs 101 and 1 02.

[0031] The PDCCH may use control channel elements (CCEs) to convey the control information. Before being mapped to resource elements, the PDCCH complex-valued symbols may first be organized into quadruplets, which may then be permuted using a sub-block interleaver for rate matching. Each PDCCH may be transmitted using one or more of these CCEs, where each CCE may correspond to nine sets of four physical resource elements known as resource element groups (REGs). Four Quadrature Phase Shift Keying (QPSK) symbols may be mapped to each REG. The PDCCH can be transmitted using one or more CCEs, depending on the size of the downlink control information (DCI) and the channel condition. There can be four or more different PDCCH formats defined in LTE with different numbers of CCEs (e.g., aggregation level, L=1 , 2, 4, or 8).

[0032] Some embodiments may use concepts for resource allocation for control channel information that are an extension of the above-described concepts. For example, some embodiments may utilize an enhanced physical downlink control channel (EPDCCH) that uses PDSCH resources for control information transmission. The EPDCCH may be transmitted using one or more enhanced the control channel elements (ECCEs). Similar to above, each ECCE may correspond to nine sets of four physical resource elements known as an enhanced resource element groups (EREGs). An ECCE may have other numbers of EREGs in some situations.

[0033] The RAN 1 1 0 is shown to be communicatively coupled to a core network (CN) 1 20— via an S1 interface 1 1 3. In embodiments, the CN 120 may be an evolved packet core (EPC) network, a NextGen Packet Core (NPC) network, or some other type of CN. In this embodiment the S1 interface 1 13 is split into two parts: the S1 -U interface 1 14, which carries traffic data between the RAN nodes 1 1 1 and 1 12 and the serving gateway (S-GW) 122, and the S1 -mobility management entity (MME) interface 1 15, which is a signaling interface between the RAN nodes 1 1 1 and 1 12 and MMEs 121 .

[0034] In this embodiment, the CN 1 20 comprises the MMEs 121 , the S-GW 122, the Packet Data Network (PDN) Gateway (P-GW) 123, and a home subscriber server (HSS) 124. The MMEs 121 may be similar in function to the control plane of legacy Serving General Packet Radio Service (GPRS) Support Nodes (SGSN). The MMEs 121 may manage mobility aspects in access such as gateway selection and tracking area list management. The HSS 124 may comprise a database for network users, including subscription-related information to support the network entities' handling of

communication sessions. The CN 120 may comprise one or several HSSs 124, depending on the number of mobile subscribers, on the capacity of the equipment, on the organization of the network, etc. For example, the HSS 124 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc.

[0035] The S-GW 122 may terminate the S1 interface 1 13 towards the RAN 1 10, and routes data packets between the RAN 1 10 and the CN 120. In addition, the S-GW 122 may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3GPP mobility. Other responsibilities may include lawful intercept, charging, and some policy enforcement.

[0036] The P-GW 123 may terminate an SGi interface toward a PDN. The P-GW 123 may route data packets between the EPC network 123 and external networks such as a network including the application server 130 (alternatively referred to as application function (AF)) via an Internet Protocol (IP) interface 125. Generally, the application server 130 may be an element offering applications that use IP bearer resources with the core network (e.g., UMTS Packet Services (PS) domain, LTE PS data services, etc.). In this embodiment, the P-GW 123 is shown to be communicatively coupled to an application server 130 via an IP communications interface 125. The application server 130 can also be configured to support one or more communication services (e.g., Voice-over-Internet Protocol (VoIP) sessions, PTT sessions, group communication sessions, social networking services, etc.) for the UEs 1 01 and 102 via the CN 120.

[0037] The P-GW 123 may further be a node for policy enforcement and charging data collection. Policy and Charging Enforcement Function (PCRF) 126 is the policy and charging control element of the CN 120. In a non-roaming scenario, there may be a single PCRF in the Home Public Land Mobile Network (HPLMN) associated with a UE's Internet Protocol Connectivity Access Network (IP-CAN) session. In a roaming scenario with local breakout of traffic, there may be two PCRFs associated with a UE's IP-CAN session: a Home PCRF (H-PCRF) within a HPLMN and a Visited PCRF (V-PCRF) within a Visited Public Land Mobile Network (VPLMN). The PCRF 126 may be communicatively coupled to the application server 130 via the P-GW 123. The application server 130 may signal the PCRF 126 to indicate a new service flow and select the appropriate Quality of Service (QoS) and charging parameters. The PCRF 126 may provision this rule into a Policy and Charging Enforcement Function (PCEF) (not shown) with the appropriate traffic flow template (TFT) and QoS class of identifier (QCI), which commences the QoS and charging as specified by the application server 130.

The components of the illustrated device 200 may be included in a UE or a RAN node. In some embodiments, the device 200 may include less elements (e.g., a RAN node may not utilize application circuitry 202, and instead include a processor/controller to process IP data received from an EPC). In some embodiments, the device 200 may include additional elements such as, for example, memory/storage, display, camera, sensor, or input/output (I/O) interface.

For example, the application circuitry 202 may include circuitry such as, but not limited to, one or more single-core or multi-core processors.

In some embodiments, some or all of the constituent components of the baseband circuitry 204 and the application circuitry 202 may be implemented together such as, for example, on a system on a chip (SOC).

[0042] In some embodiments, the baseband circuitry 204 may provide for communication compatible with one or more radio technologies. For example, in some embodiments, the baseband circuitry 204 may support communication with an evolved universal terrestrial radio access network (EUTRAN) or other wireless metropolitan area networks (WMAN), a wireless local area network (WLAN), a wireless personal area network (WPAN). Embodiments in which the baseband circuitry 204 is configured to support radio communications of more than one wireless protocol may be referred to as multi-mode baseband circuitry.

[0050] The synthesizer circuitry 206d may be configured to synthesize an output frequency for use by the mixer circuitry 206a of the RF circuitry 206 based on a frequency input and a divider control input. In some embodiments, the synthesizer circuitry 206d may be a fractional N/N+1 synthesizer.

[0051] In some embodiments, frequency input may be provided by a voltage controlled oscillator (VCO), although that is not a requirement. Divider control input may be provided by either the baseband circuitry 204 or the applications processor 202 depending on the desired output frequency. In some embodiments, a divider control input (e.g., N) may be determined from a look-up table based on a channel indicated by the applications processor 202.

[0052] Synthesizer circuitry 206d of the RF circuitry 206 may include a divider, a delay-locked loop (DLL), a multiplexer and a phase accumulator. In some embodiments, the divider may be a dual modulus divider (DMD) and the phase accumulator may be a digital phase accumulator (DPA). In some embodiments, the DMD may be configured to divide the input signal by either N or N+1 (e.g., based on a carry out) to provide a fractional division ratio. In some example embodiments, the DLL may include a set of cascaded, tunable, delay elements, a phase detector, a charge pump and a D-type flip- flop. In these embodiments, the delay elements may be configured to break a VCO period up into Nd equal packets of phase, where Nd is the number of delay elements in the delay line. In this way, the DLL provides negative feedback to help ensure that the total delay through the delay line is one VCO cycle.

[0053] In some embodiments, synthesizer circuitry 206d may be configured to generate a carrier frequency as the output frequency, while in other embodiments, the output frequency may be a multiple of the carrier frequency (e.g., twice the carrier frequency, four times the carrier frequency) and used in conjunction with quadrature generator and divider circuitry to generate multiple signals at the carrier frequency with multiple different phases with respect to each other. In some embodiments, the output frequency may be a LO frequency (fLO). In some embodiments, the RF circuitry 206 may include an IQ/polar converter.

[0054] FEM circuitry 208 may include a receive signal path which may include circuitry configured to operate on RF signals received from one or more antennas 210, amplify the received signals and provide the amplified versions of the received signals to the RF circuitry 206 for further processing. FEM circuitry 208 may also include a transmit signal path which may include circuitry configured to amplify signals for transmission provided by the RF circuitry 206 for transmission by one or more of the one or more antennas 21 0. In various embodiments, the amplification through the transmit or receive signal paths may be done solely in the RF circuitry 206, solely in the FEM 208, or in both the RF circuitry 206 and the FEM 208.

[0055] In some embodiments, the FEM circuitry 208 may include a TX/RX switch to switch between transmit mode and receive mode operation. The FEM circuitry may include a receive signal path and a transmit signal path. The receive signal path of the FEM circuitry may include an LNA to amplify received RF signals and provide the amplified received RF signals as an output (e.g., to the RF circuitry 206). The transmit signal path of the FEM circuitry 208 may include a power amplifier (PA) to amplify input RF signals (e.g., provided by RF circuitry 206), and one or more filters to generate RF signals for subsequent transmission (e.g., by one or more of the one or more antennas 210).

[0056] In some embodiments, the PMC 212 may manage power provided to the baseband circuitry 204. In particular, the PMC 21 2 may control power-source selection, voltage scaling, battery charging, or DC-to-DC conversion. The PMC 212 may often be included when the device 200 is capable of being powered by a battery, for example, when the device is included in a UE. The PMC 21 2 may increase the power conversion efficiency while providing desirable implementation size and heat dissipation

characteristics.

[0057] While FIG. 2 shows the PMC 212 coupled only with the baseband circuitry 204. However, in other embodiments, the PMC 2 12 may be additionally or alternatively coupled with, and perform similar power management operations for, other components such as, but not limited to, application circuitry 202, RF circuitry 206, or FEM 208.

[0058] In some embodiments, the PMC 212 may control, or otherwise be part of, various power saving mechanisms of the device 200. For example, if the device 200 is in an RRC_Connected state, where it is still connected to the RAN node as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the device 200 may power down for brief intervals of time and thus save power.

[0059] If there is no data traffic activity for an extended period of time, then the device 200 may transition off to an RRCJdle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, etc. The device 200 goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. The device 200 may not receive data in this state, in order to receive data, it must transition back to RRC_Connected state.

[0060] An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.

[0061] Processors of the application circuitry 202 and processors of the baseband circuitry 204 may be used to execute elements of one or more instances of a protocol stack. For example, processors of the baseband circuitry 204, alone or in combination, may be used execute Layer 3, Layer 2, or Layer 1 functionality, while processors of the application circuitry 204 may utilize data (e.g., packet data) received from these layers and further execute Layer 4 functionality (e.g., transmission communication protocol (TCP) and user datagram protocol (UDP) layers). As referred to herein, Layer 3 may comprise a radio resource control (RRC) layer, described in further detail below. As referred to herein, Layer 2 may comprise a medium access control (MAC) layer, a radio link control (RLC) layer, and a packet data convergence protocol (PDCP) layer, described in further detail below. As referred to herein, Layer 1 may comprise a physical (PHY) layer of a UE/RAN node, described in further detail below.

[0062] FIG. 3 illustrates example interfaces of baseband circuitry in accordance with some embodiments. As discussed above, the baseband circuitry 204 of FIG. 2 may comprise processors 204A-204E and a memory 204G utilized by said processors. Each of the processors 204A-204E may include a memory interface, 304A-304E,

respectively, to send/receive data to/from the memory 204G.

[0063] The baseband circuitry 204 may further include one or more interfaces to communicatively couple to other circuitries/devices, such as a memory interface 312 (e.g., an interface to send/receive data to/from memory external to the baseband circuitry 204), an application circuitry interface 314 (e.g., an interface to send/receive data to/from the application circuitry 202 of FIG. 2), an RF circuitry interface 316 (e.g., an interface to send/receive data to/from RF circuitry 206 of FIG. 2), a wireless hardware connectivity interface 31 8 (e.g., an interface to send/receive data to/from Near Field Communication (NFC) components, Bluetooth® components (e.g., Bluetooth® Low Energy), Wi-Fi® components, and other communication components), and a power management interface 320 (e.g., an interface to send/receive power or control signals to/from the PMC 212).

[0064] Referring to FIG. 4, illustrated is a block diagram of a system 400 employable at a UE (User Equipment) that facilitates configuration of QCL (Quasi Co-Location) between RS (Reference Signals) of different CCs (Component Carriers), according to various aspects described herein. System 400 can include one or more processors 410 (e.g., one or more baseband processors such as one or more of the baseband processors discussed in connection with FIG. 2 and/or FIG. 3) comprising processing circuitry and associated memory interface(s) (e.g., memory interface(s) discussed in connection with FIG. 3), transceiver circuitry 420 (e.g., comprising one or more of transmitter circuitry or receiver circuitry, which can employ common circuit elements, distinct circuit elements, or a combination thereof), and a memory 430 (which can comprise any of a variety of storage mediums and can store instructions and/or data associated with one or more of processor(s) 410 or transceiver circuitry 420). In various aspects, system 400 can be included within a user equipment (UE). As described in greater detail below, system 400 can facilitate reception of configuration signaling that indicates that AP(s) (Antenna Port(s)) for RS of a first CC are QCL-ed with APs for RS of a second CC. [0065] In various aspects discussed herein, signals and/or messages can be generated and output for transmission, and/or transmitted messages can be received and processed. Depending on the type of signal or message generated, outputting for transmission (e.g., by processor(s) 410, processor(s) 510, etc.) can comprise one or more of the following: generating a set of associated bits that indicate the content of the signal or message, coding (e.g., which can include adding a cyclic redundancy check (CRC) and/or coding via one or more of turbo code, low density parity-check (LDPC) code, tailbiting convolution code (TBCC), etc.), scrambling (e.g., based on a scrambling seed), modulating (e.g., via one of binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), or some form of quadrature amplitude modulation (QAM), etc.), and/or resource mapping (e.g., to a scheduled set of resources, to a set of time and frequency resources granted for uplink transmission, etc.). Depending on the type of received signal or message, processing (e.g., by processor(s) 410, processor(s) 51 0, etc.) can comprise one or more of: identifying physical resources associated with the signal/message, detecting the signal/message, resource element group deinterleaving, demodulation, descrambling, and/or decoding.

[0066] Referring to FIG. 5, illustrated is a block diagram of a system 500 employable at a BS (Base Station) that facilitates configuration of a UE for QCL between RS of different CCs, according to various aspects described herein. System 500 can include one or more processors 510 (e.g., one or more baseband processors such as one or more of the baseband processors discussed in connection with FIG. 2 and/or FIG. 3) comprising processing circuitry and associated memory interface(s) (e.g., memory interface(s) discussed in connection with FIG. 3), communication circuitry 520 (e.g., which can comprise circuitry for one or more wired (e.g., X2, etc.) connections and/or transceiver circuitry that can comprise one or more of transmitter circuitry (e.g., associated with one or more transmit chains) or receiver circuitry (e.g., associated with one or more receive chains), wherein the transmitter circuitry and receiver circuitry can employ common circuit elements, distinct circuit elements, or a combination thereof), and memory 530 (which can comprise any of a variety of storage mediums and can store instructions and/or data associated with one or more of processor(s) 510 or communication circuitry 520). In various aspects, system 500 can be included within an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (Evolved Node B, eNodeB, or eNB), next generation Node B (gNodeB or gNB) or other base station in a wireless communications network. In some aspects, the processor(s) 510, communication circuitry 520, and the memory 530 can be included in a single device, while in other aspects, they can be included in different devices, such as part of a distributed architecture. As described in greater detail below, system 500 can facilitate generation of configuration signaling that indicates that AP(s) (Antenna Port(s)) for RS of a first CC are QCL-ed with APs for RS of a second CC.

[0067] Referring to FIG. 6, illustrated is a diagram showing an antenna sub-array model 600 that can be employed (e.g., in connection with system 500 and/or system 600) in connection with various aspects discussed herein. For ease of illustration, two transceiver units (TXRUs) and eight physical antennas (M = 8) are shown (with four physical antennas per subarray (K = 4) in model 600) for model 600, although in various embodiments, each of these values can be greater or lesser. As can be seen in FIG. 6, model 600 comprises distinct subarrays, with each physical antenna part of a distinct subarray and associated with a single distinct TXRU (e.g., m' = 1 or m' =2).The 5G (Fifth Generation) NR (New Radio) antenna design can be largely based on the antenna sub-array concept, such as the example model 600 of FIG. 6.

[0068] The physical antenna elements of the TRP (Transmission/Reception Point, e.g., Base Station such as a gNB (next generation NodeB), an eNB (Evolved NodeB), etc.yilE can be grouped into antenna sub-arrays, where an antenna array can contain multiple subarrays. The physical antenna elements of the antenna sub-array can be virtualized to the antenna port(s) using analog beamforming (e.g., via beamforming weights selected by processor(s) 410 and applied by transceiver circuitry 420, or selected by processor(s) 51 0 and applied by processor(s) 520).

[0069] The analog beamforming (e.g., via beamforming weights selected by processor(s) 410 and applied by transceiver circuitry 420, or selected by processor(s) 51 0 and applied by processor(s) 520) can be used to improve the performance of the communication link between the TRP and the UE. The analog beamforming at the TRP and UE can be trained by transmitting a series of reference signals (e.g., generated by processor(s) 510, transmitted via communication circuitry 520, received via transceiver circuitry 420, and processed by processor(s) 410) with different beamforming (e.g., via beamforming weights selected by processor(s) 410 and applied by transceiver circuitry 420). The UE can also train the receive beamforming. The optimal analog beamforming at the UE can depend on the beamforming at the TRP, and vice versa. Multiple optimal beam combinations at the TRP and UE can be established for possible communication. Additionally, a beam training on one antenna subarray can be reused on another antenna subarray. [0070] FIG. 6 shows a subarray antenna architecture with two subarrays, where each subarray may have different analog beamforming. The analog beamforming is controlled by antenna weights w, (which can be complex valued (to control amplitude and phase) elements of a weight vector W), which can be selected by processor(s) 410 or processor(s) 51 0 and applied by transceiver circuitry 420 or communication circuitry 520, respectively.

[0071] Referring to FIG. 7, illustrated is a diagram showing multiple types of carrier aggregation that can be employed in connection with various aspects discussed herein. Carrier aggregation can be used in LTE (Long Term Evolution)-A (Advanced) systems to improve the data throughput by increasing the total bandwidth of the transmission. Carrier aggregation in LTE-A is supported starting from Rel-10 (3GPP Release 10) and can be used for both FDD (Frequency Division Duplexing) and TDD (Time Division Duplexing) systems. In FDD, the number of aggregated carriers can be different between DL (Downlink (e.g., signaling/data generated by processor(s) 510, transmitted via communication circuitry 520, received via transceiver circuitry 420, and processed by processor(s) 41 0)) and UL (Uplink (e.g., signaling/data generated by processor(s) 41 0, transmitted via transceiver circuitry 420, received via communication circuitry 520, and processed by processor(s) 510)), while for TDD the number of carriers of each carrier is typically the same. The number of DL component carriers can be higher than or the same as the number of UL carriers. The individual component carriers in DL or UL can also be of different bandwidths (e.g., of 1 .4, 3, 5, 10, 15 or 20 MHz). In LTE-A Rel-10, a maximum of five component carriers can be aggregated. However the number of carriers that can be aggregated is expected to be further increased in Rel-13 (3GPP Release 13) to be up to 32.

[0072] The easiest way to operate carrier aggregation is to aggregate contiguous component carriers within the same operating frequency band, so called intra-band contiguous carrier aggregation, as shown in the top portion of FIG. 7. However, due to spectrum allocation restrictions, this might not always be possible and non-contiguous aggregation can be used as well, as shown in the middle and bottom portions of FIG. 7. The non-contiguous carrier frequency allocation can be either intra-band (as shown in the middle portion of FIG. 7) or inter-band (as shown in the bottom portion of FIG. 7), depending on whether the aggregated component carriers belong to the same operating frequency band or belong to different operating frequency bands. [0073] In various aspects discussed herein, techniques are discussed for applying QCL (Quasi Co-Location) for antenna ports transmitted on different component carriers in CA (Carrier Aggregation) scenarios.

[0074] Referring to FIG. 8, illustrated is a diagram showing examples of cross-carrier QCL between various reference signal antenna ports, according to various aspects discussed herein. Although specific examples are provided below to illustrate various embodiments, in various aspects, other scenarios can also be employed for cross- carrier QCL between reference signal antenna ports.

[0075] In various aspects, QCL can be established between DM (Demodulation)-RS (Reference Signal) antenna port(s) transmitted on different CCs (Component Carriers). The QCL parameter set can comprise one or more other QCL parameters, such as average gain, average delay, delay spread, Doppler spread, or Doppler shift. The QCL parameters can also comprise spatial parameter(s) at the receiver (Rx), such as one or more of a mean angle of arrival (first-order statistics for an angle property of the channel), angle of arrival spread (second-order statistics for an angle property of the channel), or channel correlation. The set of component carriers where QCL is established between DM-RS antenna ports can be indicated by using higher layer (e.g., RRC (Radio Resource Control), MAC (Medium Access Control), etc.) and / or physical layer (e.g., DCI (Downlink Control Information) signaling (e.g., generated by

processor(s) 510, transmitted via communication circuitry 520, received via transceiver circuitry 420, and processed by processor(s) 410).

[0076] In various aspects, QCL can be established between DM-RS antenna port(s) transmitted on one CC and antenna port(s) of BRS (Beam Reference Signal) transmitted on another CC. The Beam Reference Signal can refer to a reference signal which can be used to acquire a set of beams that can be used for communication between a TRP and a UE. In one example, BRS can be Channel State Information Reference Signal (CSI-RS) supporting beam management. In another example, BRS can be SS (Synchronization Signal)/PBCH (Physical Broadcast Channel) which can be also used determine beam for communication. The QCL parameters can comprise one or more of average delay, delay spread, Doppler shift, Doppler spread, or average gain. The QCL parameter set can also comprise one or more other QCL parameters, for example spatial Rx (Receive) parameters, such as mean angle of arrival, angle of arrival spread, or channel correlation. Higher layer signaling and/or DCI scheduling PDSCH (e.g., generated by processor(s) 510, transmitted via communication circuitry 520, received via transceiver circuitry 420, and processed by processor(s) 410) can indicate to the UE the one or more CCs on beam reference signals that are co-located with DM-RS. The indication can be explicit or implicit. Explicit indication can comprise indication of BRS transmitted on other CC, while implicit indication can comprise indication via the other reference signal being transmitted on the same or different CC which is QCL-ed with BRS.

[0077] In various aspects, QCL can be established between DM-RS antenna port(s) transmitted on one CC and antenna port(s) of CSI (Channel State lnformation)-RS (Reference Signal) transmitted on another CC. The QCL parameters can comprise one or more of average delay, delay spread, Doppler shift, Doppler spread, or average gain. The QCL parameter set can also comprise one or more other QCL parameters, for example, spatial parameter(s) such as mean angle of arrival, angle of arrival spread, or channel correlation. Higher layer signaling and/or DCI scheduling PDSCH (e.g., generated by processor(s) 510, transmitted via communication circuitry 520, received via transceiver circuitry 420, and processed by processor(s) 410) can indicate to the UE the one or more CCs on CSI-RS that are co-located with DM-RS.

[0078] In various aspects, QCL can be established between CSI-RS antenna port(s) transmitted on one CC and CSI-RS transmitted on another CC. The QCL parameters can comprise one or more of average delay, delay spread, Doppler shift, Doppler spread, or average gain. The QCL parameter set can also comprise one or more other QCL parameters, for example, spatial Rx parameters such as mean, angle of arrival, angle of arrival spread, or channel correlation. Higher layer signaling and/or DCI scheduling for CSI-RS (e.g., generated by processor(s) 51 0, transmitted via

communication circuitry 520, received via transceiver circuitry 420, and processed by processor(s) 410) can indicate to the UE the one or more CCs on which CSI-RS are co- located with each other.

[0079] In various aspects, QCL can be established between antenna port(s) of mobility RS transmitted on one CC and antenna port(s) of other reference signals transmitted on another CC. The other reference signals can comprise, for example, CSI-RS, DM-RS, beam reference signals, tracking reference signal, etc. The QCL parameters can comprise one or more of average delay, delay spread, Doppler shift, Doppler spread, or average gain. The QCL parameter set can also comprise one or more other QCL parameters, for example, spatial Rx parameters such as mean angle of arrival, angle of arrival spread, or channel correlation. Higher layer signaling and/or DCI (e.g., generated by processor(s) 51 0, transmitted via communication circuitry 520, received via transceiver circuitry 420, and processed by processor(s) 410) can indicate to the UE the one or more CCs on mobility reference signals that are co-located with other reference signals.

[0080] In various aspects, QCL can be established between antenna port of

SS/PBCH block on one CC and antenna ports of other reference signals transmitted on another CC. The other reference signals can comprise, for example, CSI-RS, DM-RS, beam reference signals, tracking reference signal, etc. The QCL parameters can comprise one or more of average delay, delay spread, Doppler shift, Doppler spread, or average gain. The QCL parameter set can also comprise one or more other QCL parameters, e.g. spatial Rx parameters, such as mean angle of arrival, angle of arrival spread, or channel correlation. Higher layer signaling and/or DCI (e.g., generated by processor(s) 510, transmitted via communication circuitry 520, received via transceiver circuitry 420, and processed by processor(s) 410) can indicate to the UE the one or more CCs on mobility reference signals that are co-located with other reference signals.

[0088] Referring to FIG. 10, illustrated is a flow diagram of an example method 1 000 employable at a BS that facilitates configuration of a UE for QCL between RS of different CCs, according to various aspects discussed herein. In other aspects, a machine readable medium can store instructions associated with method 1000 that, when executed, can cause a BS to perform the acts of method 1000. [0089] At 1010, configuration signaling can be transmitted that indicates that first AP(s) of a first set of RS on a first CC are QCL'ed with second AP(s) of a second set of RS on a second CC, wherein the first AP(s) and the second AP(s) are QCL'ed with respect to one or more parameters discussed herein.

[0090] At 1020, the first set of RS can be transmitted via the first CC.
