[0002] This patent application claims priority to provisional application No. 62 / 780,102, filed on December 14, 2018, entitled “TECHNIQUES FOR COMMUNICATING USING MULTIPLE TRANSMISSION POINTS WIRELESS COMMUNICATIONS,” and U.S. patent application No. 16 / 712,915, filed on December 12, 2019, entitled “TECHNIQUES FOR COMMUNICATING USING MULTIPLE TRANSMISSION POINTS WIRELESS COMMUNICATIONS,” the entire contents of which are expressly incorporated herein by reference.

[0003] background

[0004] Aspects of the present disclosure relate generally to wireless communication systems, and more particularly to communicating using multiple transmission points.

[0005] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, etc. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, and orthogonal frequency division multiple access (OFDMA) systems, and single-carrier frequency division multiple access (SC-FDMA) systems.

[0006] These multiple access technologies have been adopted in various telecommunication standards to provide common protocols that enable different wireless devices to communicate at city, country, region, and even global levels. For example, the fifth generation (5G) wireless communication technology, which may be referred to as 5G New Radio (5G NR), is designed to expand and support diverse usage scenarios and applications relative to current mobile network generations. On the one hand, 5G communication technology may include: enhanced mobile broadband for human-centric use cases for accessing multimedia content, services, and data; ultra-reliable low latency communications (URLLC) with certain specifications on latency and reliability; and massive machine-type communications, which may allow a very large number of connected devices and the transmission of relatively small amounts of non-delay-sensitive information.

[0026] Detailed Description

[0027] Now, various aspects are described with reference to the accompanying drawings. In the following description, for the purpose of explanation, numerous specific details are set forth to provide a thorough understanding of one or more aspects. However, it is apparent that such aspects can be practiced without these specific details.

[0028] The described features generally relate to configuring a device to communicate with multiple transmission points (TRPs) in wireless communications. In one example, communicating with multiple TRPs may provide higher capacity, improved robustness, etc. in communications with the device. In one example, a TRP (e.g., a gNB) may be configured to activate and / or deactivate multi-TRP operation of a device. In one example, a device may be configured to identify multiple TRPs for multi-TRP operation, and the TRP may activate and / or deactivate multi-TRP operation and / or related TRPs based on a report from the device (or otherwise without a report from the device). Various signaling possibilities may be used to configure a device for multi-TRP operation, such as radio resource control (RRC) layer signaling, media access control (MAC) control elements (CE), etc. In addition, in one example, downlink control information (DCI) may be used to configure multi-TRP operation.

[0029] In a particular example, bandwidth part (BWP) switching may be used to activate and / or deactivate a TRP or otherwise switch between single-TRP operation to multiple-TRP operation and / or vice versa. As further described herein, a BWP may be configured for a given component carrier (CC) such that each CC may include one or more BWPs, and a BWP may correspond to one or more TRPs. In one example, a BWP configuration may be specified in which a given BWP may be associated with one TRP or multiple TRPs (e.g., based on the identifier(s) of the TRP(s) included in the BWP configuration). For example, a BWP may be a portion of the bandwidth of the corresponding CC, and thus each CC may include one or more BWPs. In addition, each BWP may include different or overlapping portions of the bandwidth, and thus each BWP may be configured for a given CC jointly or separately depending on whether the corresponding bandwidths overlap.

[0030] In another example, various parameters in the DCI may be used to activate and / or deactivate a TRP or otherwise switch between single-TRP operation to multiple-TRP operation and / or vice versa. For example, a quasi-co-location (QCL) relationship specified in a TCI state in the DCI may indicate whether multiple-TRP operation or single-TRP operation is to be used and / or the configuration of the TRP to be used. In any case, multiple-TRP operation may be enabled for a device to facilitate improved capacity / robustness in wireless communications.

[0031] The following will refer to Figure 1-6 The described features are presented in more detail.

[0032] As used in this application, the terms "component", "module", "system" and similar terms are intended to include computer-related entities, such as but not limited to hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component can be, but not limited to, a process, a processor, an object, an executable, a thread of execution, a program, and / or a computer running on a processor. As an illustration, both an application running on a computing device and the computing device can be a component. One or more components may reside in a process and / or a thread of execution, and a component may be localized on a computer and / or distributed between two or more computers. In addition, these components can be executed from various computer-readable media on which various data structures are stored. These components can communicate by means of local and / or remote processes, such as according to a signal having one or more data packets, such as data from a component that interacts with a local system, another component in a distributed system, and / or interacts with other systems across a network such as the Internet.

[0033] The technology described herein can be used for various wireless communication systems, such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other systems. The terms "system" and "network" are usually used interchangeably. A CDMA system can implement radio technologies such as CDMA2000, Universal Terrestrial Radio Access (UTRA). CDMA2000 covers IS-2000, IS-95 and IS-856 standards. IS-2000 versions 0 and A are often referred to as CDMA2000 1X, 1X, etc. IS-856 (TIA-856) is often referred to as CDMA2000 1xEV-DO, High Rate Packet Data (HRPD), etc. UTRA includes Wideband CDMA (WCDMA) and other CDMA variants. A TDMA system can implement radio technologies such as Global System for Mobile Communications (GSM). OFDMA systems can implement technologies such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM TM Radio technologies such as UTRA and E-UTRA are parts of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and Advanced LTE (LTE-A) are new UMTS versions that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization called the "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization called the "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies, including cellular (e.g., LTE) communications on shared radio frequency spectrum bands. However, the following description describes an LTE / LTE-A system for example purposes, and LTE terminology is used in most of the following descriptions, but these techniques can also be applied to applications other than LTE / LTE-A (e.g., to fifth generation (5G) new radio (NR) networks or other next generation communication systems).

[0034] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements discussed without departing from the scope of the present disclosure. Various examples may appropriately omit, substitute, or add various procedures or components. For example, the described methods may be performed in an order different from that described, and various steps may be added, omitted, or combined. In addition, features described with reference to some examples may be combined in other examples.

[0035] Various aspects or features will be presented in the form of systems that may include a number of devices, components, modules, and the like, etc. It should be understood and appreciated that the various systems may include additional devices, components, modules, etc., and / or may not include all of the devices, components, modules, etc. discussed in conjunction with the figures. Combinations of these approaches may also be used.

[0036] Figure 1 1 is a diagram illustrating an example of a wireless communication system and access network 100. The wireless communication system (also referred to as a wireless wide area network (WWAN)) may include a base station 102, a UE 104, an evolved packet core (EPC) 160, and / or a 5G core (5GC) 190. The base station 102 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). The macro cell may include a base station. The small cell may include a femto cell, a pico cell, and a micro cell. In one example, the base station 102 may also include a gNB 180, as further described herein. In one example, some nodes of the wireless communication system may have a modem 240 and a communication component 242 for communicating with multiple TRPs, and some nodes may have a modem 340 and a TRP configuration component 342 for configuring the device to communicate with multiple TRPs, as described herein. Although UE 104 is shown as having a modem 240 and a communication component 242 and base station 102 / gNB 180 is shown as having a modem 340 and a TRP configuration component 342, this is an illustrative example and substantially any node or type of node may include a modem 240 and a communication component 242 and / or a modem 340 and a TRP configuration component 342 to provide the corresponding functionality described herein.

[0037] The base station 102 configured for 4G LTE (which may be collectively referred to as the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC 160 via a backhaul link 132 (e.g., using an S1 interface). The base station 102 configured for 5G NR (which may be collectively referred to as the Next Generation RAN (NG-RAN)) may interface with the 5GC 190 via a backhaul link 184. The base station 102 may perform, among other functions, one or more of the following functions: delivery of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment tracking, RAN information management (RIM), paging, positioning, and delivery of alert messages. Base stations 102 may communicate with each other directly or indirectly (e.g., through EPC 160 or 5GC 190) over backhaul link 134 (e.g., using an X2 interface). Backhaul link 134 may be wired or wireless.

[0038] The base station 102 may communicate wirelessly with one or more UEs 104. Each base station 102 may provide communication coverage for a corresponding geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, a small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of one or more macro base stations 102. A network including both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include a home evolved Node B (eNB) (HeNB), which may provide services to a restricted group (which may be referred to as a closed subscriber group (CSG)). The communication link 120 between the base station 102 and the UE 104 may include an uplink (UL) (also known as a reverse link) transmission from the UE 104 to the base station 102 and / or a downlink (DL) (also known as a forward link) transmission from the base station 102 to the UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. These communication links may be through one or more carriers. For each carrier allocated in a carrier aggregation of up to Yx MHz (e.g., for x component carriers) for transmission in the DL and / or UL direction, the base station 102 / UE 104 may use a spectrum of up to Y MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.) bandwidth. These carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL). The component carrier may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell), and the secondary component carrier may be referred to as a secondary cell (SCell).

[0039] In another example, some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use DL / UL WWAN spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). The D2D communication may be through a variety of wireless D2D communication systems, such as, for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0040] The wireless communication system may further include a Wi-Fi access point (AP) 150 communicating with a Wi-Fi station (STA) 152 in the 5 GHz unlicensed spectrum via a communication link 154. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) prior to communication to determine whether the channel is available.

[0041] The small cell 102' may operate in a licensed and / or unlicensed spectrum. When operating in an unlicensed spectrum, the small cell 102' may employ NR and use the same 5 GHz unlicensed spectrum as used by the Wi-Fi AP 150. The small cell 102' employing NR in the unlicensed spectrum may boost the coverage of the access network and / or increase the capacity of the access network.

[0042] Whether a small cell 102' or a large cell (e.g., a macro base station), the base station 102 may include an eNB, a gB node (gNB), or other types of base stations. Some base stations (such as gNB 180) may operate in traditional sub-6 GHz spectrum, millimeter wave (mmW) frequencies, and / or near mmW frequencies to communicate with UE 104. When gNB 180 operates in mmW or near mmW frequencies, gNB 180 may be referred to as a mmW base station. Extremely high frequency (EHF) is part of the RF in the electromagnetic spectrum. EHF has a range of 30 GHz to 300 GHz and a wavelength between 1 mm and 10 mm. The radio waves in this band may be referred to as millimeter waves. Near mmW can be extended down to 3 GHz frequencies with a wavelength of 100 mm. The super high frequency (SHF) band extends between 3 GHz and 30 GHz, which is also referred to as centimeter waves. Communications using mmW / near mmW radio frequency bands have extremely high path loss and short range. The mmW base station 180 may utilize beamforming 182 with the UE 104 to compensate for the extremely high path loss and short range. The base station 102 referred to herein may include a gNB 180.

[0043] The EPC 160 may include a mobility management entity (MME) 162, other MMEs 164, a serving gateway 166, a multimedia broadcast multicast service (MBMS) gateway 168, a broadcast multicast service center (BM-SC) 170, and a packet data network (PDN) gateway 172. The MME 162 may be in communication with a home subscriber server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. In general, the MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are delivered through the serving gateway 166, which itself is connected to the PDN gateway 172. The PDN gateway 172 provides UE IP address allocation and other functions. The PDN gateway 172 and the BM-SC 170 are connected to IP services 176. The IP services 176 may include the Internet, an intranet, an IP multimedia subsystem (IMS), a PS streaming service, and / or other IP services. The BM-SC 170 may provide functionality for MBMS user service provisioning and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS transmissions, may be used to authorize and initiate MBMS bearer services within a public land mobile network (PLMN), and may be used to schedule MBMS transmissions. The MBMS gateway 168 may be used to distribute MBMS traffic to base stations 102 belonging to a multicast broadcast single frequency network (MBSFN) area that broadcasts a specific service, and may be responsible for session management (start / stop) and for collecting eMBMS-related charging information.

[0044] 5GC 190 may include an access and mobility management function (AMF) 192, other AMFs 193, a session management function (SMF) 194, and a user plane function (UPF) 195. AMF 192 may be in communication with a unified data management (UDM) 196. AMF 192 may be a control node that processes signaling between UE 104 and 5GC 190. In general, AMF 192 may provide QoS flow and session management. User Internet Protocol (IP) packets (e.g., from one or more UEs 104) may be delivered via UPF 195. UPF 195 may provide UE IP address allocation for one or more UEs and other functions. UPF 195 is connected to IP services 197. IP services 197 may include the Internet, an intranet, an IP multimedia subsystem (IMS), a PS streaming service, and / or other IP services.

[0045] A base station may also be referred to as a gNB, a Node B, an evolved Node B (eNB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmission reception point (TRP), or some other suitable term. The base station 102 provides an access point to the EPC 160 or the 5GC 190 for the UE 104. Examples of UE 104 include a cellular phone, a smart phone, a Session Initiation Protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., an MP3 player), a camera, a game console, a tablet device, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a health care device, an implant, a sensor / actuator, a display, or any other similar functional device. Some UEs 104 may be referred to as IoT devices (e.g., parking meters, gas pumps, ovens, vehicles, heart monitors, etc.). IoT UEs may include machine type communication (MTC) / enhanced MTC (eMTC, also known as Category (CAT)-M, Cat M1) UEs, NB-IoT (also known as CAT NB1) UEs, and other types of UEs. In the present disclosure, eMTC and NB-IoT may refer to future technologies that may evolve from or be based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (further enhanced eMTC), mMTC (massive MTC), etc., and NB-IoT may include eNB-IoT (enhanced NB-IoT), FeNB-IoT (further enhanced NB-IoT), etc. UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable term.

[0046] In one example, the communication component 242 may activate and / or deactivate communications with one or more TRPs to establish multi-TRP (or single TRP) operation, which may or may not be based on a configuration received from one or more of the TRPs. In addition, the TRP configuration component 342 may configure communications on multiple TRPs based on one or more parameters of the configuration provided to the device, as further described herein. In one example, the TRP may be a base station 102 (such as a gNB), and the device may be a UE 104 configured to communicate with the base station 102 and / or other TRPs (e.g., other base stations 102, etc.). In one example, multiple TRPs may be configured to operate in mode 1, which corresponds to an ideal backhaul, such that one TRP (e.g., on a physical downlink control channel (PDCCH)) transmits control information for multiple TRPs and / or a specific layer of the same PDCCH communication may transmit control information for a specific TRP. In another example, multiple TRPs may be configured to operate in Mode 2, which corresponds to a non-ideal backhaul such that each TRP may transmit its own control information (e.g., on its own PDCCH).

[0047] Now go to Figure 2-6 , various aspects are described with reference to one or more components and one or more methods that can perform the actions or operations described herein, where various aspects in dashed lines may be optional. Figure 4-5 The operations described in the description are presented in a particular order and / or are presented as being performed by example components, but it should be understood that the order of these actions and the components performing the actions may vary depending on the implementation. Moreover, it should be understood that the following actions, functions, and / or components described may be performed by a specially programmed processor, a processor executing specially programmed software or computer-readable media, or by any other combination of hardware components and / or software components capable of performing the described actions or functions.

[0048] Reference Figure 2 , an example of an implementation of UE 104 may include various components, some of which have been described above and are further described herein, including components such as one or more processors 212 and memory 216 in communication via one or more buses 244 and a transceiver 202, which may operate in conjunction with a modem 240 and / or a communication component 242 to enable communication with multiple TRPs.

[0049] In one aspect, the one or more processors 212 may include a modem 240 using one or more modem processors and / or may be part of the modem 240. Thus, various functions associated with the communication component 242 may be included in the modem 240 and / or the processor 412, and in one aspect, may be performed by a single processor, while in other aspects, different ones of these functions may be performed by a combination of two or more different processors. For example, in one aspect, the one or more processors 212 may include any one or any combination of the following: a modem processor, or a baseband processor, or a digital signal processor, or a transmit processor, or a receiver processor, or a transceiver processor associated with the transceiver 202. In other aspects, some of the features of the one or more processors 212 and / or the modem 240 associated with the communication component 242 may be performed by the transceiver 202.

[0050] In addition, the memory 216 can be configured to store local versions of data and / or applications 275 used herein, or the communication component 242 and / or one or more subcomponents thereof executed by the at least one processor 212. The memory 216 may include any type of computer-readable medium usable by a computer or the at least one processor 212, such as a random access memory (RAM), a read-only memory (ROM), a tape, a magnetic disk, an optical disk, a volatile memory, a non-volatile memory, and any combination thereof. In one aspect, for example, when the UE 104 is operating the at least one processor 212 to execute the communication component 242 and / or one or more subcomponents thereof, the memory 216 may be a non-transitory computer-readable storage medium storing one or more computer-executable codes defining the communication component 242 and / or one or more subcomponents thereof and / or data associated therewith.

[0051] The transceiver 202 may include at least one receiver 206 and at least one transmitter 208. The receiver 206 may include hardware, firmware, and / or software code executable by a processor for receiving data, the code including instructions and stored in a memory (e.g., a computer-readable medium). The receiver 206 may be, for example, a radio frequency (RF) receiver. In one aspect, the receiver 206 may receive signals transmitted by at least one base station 102. Additionally, the receiver 206 may process such received signals and may also obtain measurements of the signals, such as, but not limited to, Ec / Io, signal-to-noise ratio (SNR), reference signal received power (RSRP), received signal strength indicator (RSSI), etc. The transmitter 208 may include hardware, firmware, and / or software code executable by a processor for transmitting data, the code including instructions and stored in a memory (e.g., a computer-readable medium). Suitable examples of the transmitter 208 may include, but are not limited to, an RF transmitter.

[0052] Also, in an aspect, the UE 104 may include an RF front end 288 that may operate in communication with the one or more antennas 265 and the transceiver 202 for receiving and transmitting radio transmissions, such as wireless communications transmitted by at least one base station 102 or wireless transmissions transmitted by the UE 104. The RF front end 288 may be connected to the one or more antennas 265 and may include one or more low noise amplifiers (LNAs) 290, one or more switches 292, one or more power amplifiers (PAs) 298, and one or more filters 296 for transmitting and receiving RF signals.

[0053] In one aspect, the LNA 290 can amplify the received signal to a desired output level. In one aspect, each LNA 290 can have a specified minimum and maximum gain value. In one aspect, the RF front end 288 can use one or more switches 292 to select a particular LNA 290 and its specified gain value based on the desired gain value for a particular application.

[0054] In addition, for example, one or more PAs 298 can be used by the RF front end 288 to amplify the signal to obtain an RF output at a desired output power level. In one aspect, each PA 298 can have a specified minimum and maximum gain value. In one aspect, the RF front end 288 can use one or more switches 292 to select a particular PA 298 and its specified gain value based on the desired gain value for a particular application.

[0055] In addition, for example, one or more filters 296 can be used by the RF front end 288 to filter the received signal to obtain the input RF signal. Similarly, in one aspect, for example, a corresponding filter 296 can be used to filter the output from the corresponding PA 298 to produce an output signal for transmission. In one aspect, each filter 296 can be connected to a specific LNA 290 and / or PA 298. In one aspect, the RF front end 288 can use one or more switches 292 to select a transmit or receive path using a specified filter 296, LNA 290, and / or PA 298 based on a configuration as specified by the transceiver 202 and / or the processor 212.

[0056] As such, the transceiver 202 may be configured to transmit and receive wireless signals through one or more antennas 265 via the RF front end 288. In an aspect, the transceiver may be tuned to operate at a specified frequency so that the UE 104 may communicate, for example, with one or more base stations 102 or one or more cells associated with the one or more base stations 102. In an aspect, the modem 240 may configure the transceiver 202 to operate at a specified frequency and power level based on, for example, a UE configuration of the UE 104 and a communication protocol used by the modem 240.

[0057] In one aspect, modem 240 may be a multi-band-multi-mode modem that may process digital data and communicate with transceiver 202 so that digital data is sent and received using transceiver 202. In one aspect, modem 240 may be multi-band and configured to support multiple frequency bands for a specific communication protocol. In one aspect, modem 240 may be multi-mode and configured to support multiple operating networks and communication protocols. In one aspect, modem 240 may control one or more components (e.g., RF front end 288, transceiver 202) of UE 104 to enable transmission and / or reception of signals from the network based on a specified modem configuration. In one aspect, modem configuration may be based on the mode of the modem and the frequency band used. In another aspect, modem configuration may be based on UE configuration information associated with UE 104, such as provided by the network during cell selection and / or cell reselection.

[0058] In an aspect, the communication component 242 may optionally include a TRP configuration component 252 for configuring multi-TRP (or single TRP) operation. The TRP configuration component 252 may optionally include a TRP identification component 254 for identifying and / or reporting the identification of a TRP, a BWP switching component 256 for obtaining a configuration of a BWP for switching CCs (which may also indicate activation and / or deactivation of one or more TRPs), and / or a DCI processing component for processing received DCI (which may indicate activation and / or deactivation of one or more TRPs).

[0059] In one aspect, the processor(s) 212 may correspond to a Figure 6 Similarly, the memory 216 may correspond to one or more of the processors described in conjunction with the UE. Figure 6 The memory described by the UE in.

[0060] Reference Figure 3 , an example of an implementation of a base station 102 (e.g., base station 102 and / or gNB 180, as described above) may include various components, some of which have been described above, but also include components such as one or more processors 312 and memory 316 in communication via one or more buses 344 and a transceiver 302, which may operate in conjunction with a modem 340 and a TRP configuration component 342 to configure multiple TRPs for communication with a UE 104.

[0061] The transceiver 302, receiver 306, transmitter 308, one or more processors 312, memory 316, application 375, bus 344, RF front end 388, LNA 390, switch 392, filter 396, PA 398, and one or more antennas 365 may be the same as or similar to corresponding components of UE 104 as described above, but are configured or otherwise programmed for base station operation rather than UE operation.

[0062] In one aspect, the TRP configuration component 342 may optionally include a BWP switching configuration component 352 for configuring switching of the BWP of the CC in conjunction with the UE 104 (which may result in activation and / or deactivation of the TRP), and / or a DCI reporting component 354 for reporting DCI to the UE 104 (which may result in activation and / or deactivation of the TRP).

[0063] In one aspect, processor(s) 312 may correspond to a combination of Figure 6 Similarly, the memory 316 may correspond to one or more of the processors described in the base station in FIG. Figure 6 The memory described in the base station.

[0064] Figure 4 A flowchart illustrating an example of a method 400 for configuring multi-TRP (or single TRP) operation. In one example, UE 104 may use Figure 1-2 One or more components described in the method 400 may be used to perform the functions described in the method 400.

[0065] In method 400, at block 402, communication may be performed in a wireless network based on a configured set of one or more TRPs. In one aspect, communication component 242 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, etc.) may communicate in a wireless network based on a configured set of one or more TRPs. For example, the set of one or more TRPs may include a base station 102 (e.g., a gNB) serving UE 104. In one example, UE 104 may initialize communication with base station 102 at least in part by performing a random access channel (RACH) procedure with base station 102. In addition, the set of one or more TRPs may include other gNBs and / or corresponding cells with which UE 104 may communicate. In one example, serving base station 102 may transmit a configuration of a set of one or more TRPs to UE 104, which may include an initial configuration of a set of one or more TRPs, as further described herein. For example, UE 104 may receive configuration RRC signaling, MAC-CE, etc. from base station 102.

[0066] In method 400, optionally at block 404, at least one additional TRP may be identified. In one aspect, a TRP identification component 254 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, communication component 242, TRP configuration component 252, etc.) may identify at least one additional TRP. For example, the TRP identification component 254 may identify the TRP as a neighboring base station that transmits a signal received by the UE 104. For example, the TRP identification component 254 may identify the additional TRP based on a cell identifier or other identifier announced in signaling from the additional TRP. For example, each TRP may be associated with a different cell identifier or associated with the same cell identifier but in a different location / group. Thus, each TRP may be distinguished based on the cell identifier or another identifier (e.g., without signaling the cell identifier to the device), such as an implicit ControlResourceSet (CORESET) identifier announced by each TRP, a transmission configuration indicator (TCI) state, etc. Additionally, the TRP identification component 254 can identify additional TRPs based on additional TRP signal strengths reaching a threshold, based on other information advertised by the TRP, etc. The additional TRPs can include another base station (e.g., a gNB), another cellular cell, a different type of access point, etc.

[0067] In method 400, optionally at block 406, at least one additional TRP may be notified to one or more TRPs. In one aspect, TRP identification component 254 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, communication component 242, TRP configuration component 252, etc.) may notify one or more TRPs of at least one additional TRP. For example, TRP identification component 254 may notify one of the TRPs in a set of one or more TRPs (e.g., serving base station 102) of at least one additional TRP. In one example, this may include a request to add at least one additional TRP to a set of TRPs for communication in a wireless network. In one example, TRP identification component 254 may identify multiple TRPs (e.g., based on their different identifiers or other announced parameters) and may notify the multiple TRPs to request activation of communications with all or a subset of the multiple TRPs.

[0068] In method 400, at block 408, an instruction to modify a set of one or more TRPs may be received. In one aspect, a TRP configuration component 252 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, communication component 242, etc.) may receive an instruction to modify a set of one or more TRPs. For example, the TRP configuration component 252 may receive the instruction from one or more TRPs in a set of one or more TRPs by which wireless network communications are configured (e.g., a serving base station 102). Additionally, the instruction may indicate that one or more TRPs to be added to the set are to be activated (e.g., to generate a modified set of TRPs), one or more TRPs from the set are to be deactivated (e.g., to generate a modified set), and the like. Thus, for example, the instruction may identify one or more TRPs for activation and / or deactivation of communications therewith, which may be based on an associated identifier specified in the instruction. As described above, the identifiers of the one or more TRPs may include a cell identifier, an identifier associated with a CORESET, and the like. In one example, the instruction may be received in response to being notified of at least one additional TRP, and the instruction may relate to adding the at least one TRP to the set.

[0069] In the received instruction at block 408, optionally at block 410, the instruction may be received to switch the BWP. In one aspect, the BWP switching component 256 (e.g., in combination with the processor(s) 212, the memory 216, the transceiver 202, the communication component 242, the TRP configuration component 252, etc.) may receive the instruction to switch the BWP. As described, the BWP may correspond to a CC configured for the UE 104 by one or more TRPs in the current set of TRP(s), wherein a CC may have multiple BWPs and a BWP may have multiple TRPs. In this regard, the base station 102 may configure the BWP to be used in the CC for communication with the UE 104. In this example, the base station 102 may configure single TRP operation or multiple TRP operation (and / or activate / deactivate the TRP accordingly) based on the configured one or more BWPs.

[0070] In one example, in method 400, optionally at block 412, a configuration of a BWP and an associated TRP may be received. In one aspect, a BWP switching component 256 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, communication component 242, TRP configuration component 252, etc.) may receive a configuration of a BWP and an associated TRP. For example, the BWP switching component 256 may receive a configuration of a BWP from a gNB (e.g., base station 102) or other network node, and the configuration may identify a configurable BWP (the configuration may be dynamically switched between configurable BWPs) and an associated TRP. As further described below, each BWP may be configured for either single-TRP operation or multi-TRP operation, and the configuration may identify the TRP(s) associated with each BWP accordingly. Moreover, as described, identification of a TRP may be accomplished by an identifier of a TRP indicated in a BWP configuration for a given BWP (e.g., an identifier associated with a CORESET). In one example, UE 104 may receive the initial BWP configuration in RRC signaling, in MAC-CE, etc., and / or may subsequently receive dynamic BWP switching information (e.g., instructions to switch at box 410) from one or more base stations 102 in DCI, as further described herein.

[0071] In a particular example, some BWPs may be configured to correspond to multi-TRP operation and some BWPs may correspond to single-TRP operation. In another example, one or more BWPs may be associated with a different TRP than the serving base station 102, and thus multi-TRP operation may be configured by configuring BWPs corresponding to different TRPs. The BWP switching component 256 may receive instructions to switch one or more BWPs as part of a DCI received from the base station 102 (e.g., in a DCI, on a control channel such as a physical downlink control channel (PDCCH)). In addition, in one example, the BWP switching command itself (e.g., regardless of BWP or for a given BWP or a configured set of BWPs) may indicate whether multi-TRP operation is enabled.

[0072] Moreover, in one example, BWP switching (and thus TRP configuration for multi-TRP operation) can be timer-based. In this example, the BWP switching component 256 can operate using a switched BWP (as described below) based on a timer, and after the timer expires, the BWP switching component 256 can switch back to the original BWP and thus switch back to the original corresponding configuration of the TRP(s) (e.g., as a single TRP operation or a multi-TRP operation).

[0073] In another example, in the received instruction at block 408, optionally at block 412, a DCI having one or more parameters indicating the instruction may be received. In one aspect, the DCI processing component 258 (e.g., in combination with the processor(s) 212, the memory 216, the transceiver 202, the communication component 242, the TRP configuration component 252, etc.) may receive a DCI having one or more parameters indicating the instruction. For example, the DCI processing component 258 may receive the DCI from a TRP (such as a serving base station 102), and may receive the DCI on a PDCCH. In an example, the DCI may indicate the instruction to enable multi-TRP (or single TRP) operation based on one or more of its parameters (such as TCI state information, QCL configuration, etc. in the DCI). In one example, the UE 104 may receive (e.g., from the serving base station 102 or otherwise from a TRP in an initial set of TRP(s)) an initial TCI state or a configuration of a possible TCI state, which may include an indication of an initial QCL configuration or a possible QCL configuration.

[0074] In one example, for a mode 1 configuration associated with an ideal backhaul, a TCI state received from a base station 102 in a DCI may point to one or more QCL relationships, where the QCL relationships may each indicate a set of one or more reference signals for the UE 104 to monitor. When the TCI state points to multiple QCL relationships, this may indicate a multi-TRP configuration. For example, each reference signal set may correspond to a different TRP that the UE 104 may monitor. In another example, a QCL relationship may be used to specify a TRP group or TRP subgroup by which wireless communications are configured (e.g., each QCL relationship may correspond to a specific group or specific subgroup of multiple TRPs or to a single TRP). Such a configuration may be used even if the scheduling offset is below a threshold (e.g., the actual QCL used may fall back to a default QCL, or a default pair in this case, but the DCI processing component 258 may still determine whether a single TRP or multiple TRPs are granted).

[0075] In another example, for a Mode 2 configuration associated with a non-ideal backhaul, each TRP can transmit its own DCI. In this example, the DCI processing component 258 can process DCI from each of the multiple TRPs and can determine whether to operate using a single TRP or multiple TRPs and / or which TRPs to communicate with based on the TCI states and corresponding QCL relationships of all detected DCIs.

[0076] In either case, the configuration of the QCL group (e.g., possible QCL relationship groups) may also be used to set the TRP(s) to be activated / deactivated. For example, the QCL group configuration may typically include an RRC and / or MAC-CE configuration as described, and the TRP configuration component 252 may receive QCL group information that deletes certain QCL relationships or corresponding TCI states in the new RRC / MAC-CE configuration, and may determine whether to activate or deactivate the TRP accordingly based on the added / deleted QCL group or corresponding TCI state. For example, if for UE 104, the candidate TRP is to be switched from the TRP set {1,2,3} to the TRP set {2,3,4}, the received RRC / MAC-CE configuration may delete the QCL group and / or TCI state for TRP1 and may add the QCL group and / or TCI state for TRP4.

[0077] For example, determining whether to operate with a single TRP or with multiple TRPs (as described herein) may include determining whether the set of TRPs to be activated and / or deactivated results in a set containing one TRP (thus, single TRP operation) or a set containing multiple TRPs (thus, multiple TRP operation). Additionally, for example, determining whether to operate with a single TRP or with multiple TRPs may include activating or deactivating communications with one or more TRPs, as further described below.

[0078] In method 400, at block 416, a set of one or more TRPs may be modified based on the instruction to generate a modified set of one or more TRPs. In one aspect, a TRP configuration component 252 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, communication component 242, etc.) may modify a set of one or more TRPs based on the instruction to generate a modified set of one or more TRPs. For example, the TRP configuration component 252 may modify the set based at least in part on adding an identifier of a TRP to the set, deleting an identifier of a TRP from the set, and so on. The modified set may be used to determine a set of one or more TRPs to communicate with in a wireless network, which communication may include communicating in a single TRP configuration having one TRP, or communicating in a multi-TRP configuration having multiple TRPs, depending on the number of TRPs in the set. In addition, communicating with a set containing TRP(s) may include monitoring for signals from a set containing TRP(s), transmitting communications to a set containing TRP(s), and so on.

[0079] In one example, where the received instruction is an instruction to switch a BWP, the TRP configuration component 252 may identify a TRP associated with the switched BWP. In one example, the instruction may identify the BWP(s) for switching (e.g., using identifiers of the BWP(s), which may have been specified in the configuration of the BWP and the associated TRPs received in block 412). In this example, the TRP configuration component 252 may determine the TRP associated with the identified BWP based on the received configuration (e.g., based on determining which TRPs are identified as being associated with the identifiers of the BWP(s) indicated in the instruction). The TRP configuration component 252 may accordingly generate a modified set of one or more TRPs to include the identified TRP, thereby facilitating communication with the set of one or more TRPs as part of the BWP switching.

[0080] In modifying the set of one or more TRPs in block 416, optionally in block 418, one or more TRPs may be activated to generate a modified set. In one aspect, the TRP configuration component 252 (e.g., in combination with the processor(s) 212, the memory 216, the transceiver 202, the communication component 242, etc.) may activate one or more TRPs (e.g., activate communication with the one or more TRPs) to generate a modified set. In one example, activating one or more TRPs may include adding an identifier of the TRP to the set, as described above. In addition, activating one or more TRPs may include transmitting certain signaling to one or more TRPs to indicate activation thereof (e.g., transmitting a RACH sequence thereto), monitoring to look for signals from one or more TRPs, and the like. In one example, the TRP configuration component 252 may determine whether to activate one or more TRPs based on comparing the set of one or more TRPs with one or more parameters in the instruction (e.g., an identifier of a TRP to be added or an identifier of a TRP to be included in the set).

[0081] In modifying the set of one or more TRPs in box 416, one or more TRPs may optionally be deactivated in box 420 to generate a modified set. In one aspect, the TRP configuration component 252 (e.g., in combination with the processor(s) 212, the memory 216, the transceiver 202, the communication component 242, etc.) may deactivate one or more TRPs (e.g., deactivate communications with the one or more TRPs) to generate a modified set. In one example, deactivating one or more TRPs may include removing an identifier of the TRP from the set, as described above. In addition, deactivating one or more TRPs may include transmitting certain signaling to one or more TRPs to indicate their deactivation, suppressing monitoring to look for signals from one or more TRPs, and the like. In one example, the TRP configuration component 252 may determine whether to deactivate one or more TRPs based on comparing the set of one or more TRPs with one or more parameters in the instruction (e.g., an identifier of a TRP to be removed or an identifier of a TRP to be included in the set).

[0082] In method 400, at block 422, a modified set of one or more TRPs may be communicated in a wireless network. In one aspect, communication component 242 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, etc.) may communicate in a wireless network based on the modified set of one or more TRPs. As described, communicating with the modified set of one or more TRPs may include monitoring for signals received from each TRP in the modified set, transmitting communications to each TRP in the modified set, etc. In one example, communication component 242 may continue to communicate with the modified set of one or more TRPs until another modification instruction is received.

[0083] In another example, in method 400, optionally at block 424, expiration of a timer may be detected after communicating based on a modified set of one or more TRPs. In one aspect, TRP configuration component 252 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, communication component 242, etc.) may detect expiration of a timer. As described, for example, communicating with a modified set of one or more TRPs may be timer-based, such that TRP configuration component 252 may initialize a timer based on modifying the set (e.g., at least for multi-TRP operation) at block 416, communicating with a modified set of TRPs at block 422, etc. In one example, however, the timer may be a timer used to ensure that a modified set of one or more TRPs is properly configured, and thus may be canceled or reset upon receiving a communication from a set of one or more TRPs (e.g., via an associated BWP, etc.).

[0084] In any case, upon detection of expiration of the timer at block 424, optionally at block 426, communications may be conducted in the wireless network with the configured set of one or more TRPs. In one aspect, communication component 242 (e.g., in conjunction with processor(s) 212, memory 216, transceiver 202, etc.) may communicate in the wireless network based on the configured set of one or more TRPs (e.g., the originally configured set used at block 402). For example, in this example, TRP configuration component 252 may activate communications with one or more TRPs in the configured set and / or deactivate communications with one or more TRPs in the modified set, as described above.

[0085] Figure 5 A flowchart illustrating an example of a method 500 for configuring single TRP operation or multi-TRP operation for a UE 104. In one example, a base station 102 (e.g., which may include a gNB 180) may use Figure 1 and 3 One or more components described in the method 500 may be used to perform the functions described in the method 500.

[0086] In method 500, at box 502, a UE may be configured with a configured set of one or more TRPs for communication in a wireless network. In one aspect, a TRP configuration component 342 (e.g., in combination with processor(s) 312, memory 316, transceiver 302, etc.) may configure a UE (e.g., UE 104) to have a configured set of one or more TRPs for communication in a wireless network. For example, the configured set of one or more TRPs may include a base station 102 and / or additional TRPs. For example, the configuration may originate from a RACH procedure performed by UE 104 to communicate with base station 102. In addition, the set of one or more TRPs may include other gNBs and / or corresponding cells with which UE 104 can communicate. In one example, a serving base station 102 may transmit a configuration of a set of one or more TRPs to UE 104, which may include an initial configuration of a set of one or more TRPs, as further described herein. For example, base station 102 may transmit the configuration using RRC signaling, MAC-CE, etc.

[0087] In method 500, optionally at block 504, an indication of at least one additional TRP may be received from a UE. In one aspect, TRP configuration component 342 (e.g., in combination with processor(s) 312, memory 316, transceiver 302, etc.) may receive an indication of at least one additional TRP from a UE (e.g., UE 104). For example, as described, UE 104 may discover at least one additional TRP and / or may determine that communication with at least one additional TRP may be desirable (e.g., where signal properties of the additional TRPs reach a threshold), etc. In one example, TRP configuration component 342 may receive the indication in a measurement report or other communication from UE 104 on a control channel (e.g., a physical uplink control channel (PUCCH)).

[0088] In method 500, at block 506, instructions may be transmitted to the UE to modify a set of one or more TRPs to perform at least one of the following operations: activating at least one TRP for the set of one or more TRPs or deactivating at least one TRP from the set of one or more TRPs. In one aspect, TRP configuration component 342 (e.g., in combination with processor(s) 312, memory 316, transceiver 302, etc.) may transmit instructions to a UE (e.g., UE 104) to modify a set of one or more TRPs to perform at least one of the following operations: activating communication with at least one TRP for the set of one or more TRPs or deactivating communication with at least one TRP from the set of one or more TRPs. In one example, TRP configuration component 342 may determine to modify the set based on an indication of an additional TRP received from the UE. In another example, the TRP configuration component 342 may determine to modify the set based on one or more metrics of communication with the UE 104 (e.g., throughput, buffer status report (BSR), etc.) and based on knowledge of additional TRPs in the vicinity of the UE, thereby providing additional throughput to the UE 104 by activating the TRP or recalling throughput by deactivating the TRP when it is no longer needed, etc.

[0089] In any case, for example, TRP configuration component 342 can indicate in the instruction the identifiers of one or more TRPs to be added or activated and / or the identifiers of one or more TRPs to be removed or deactivated. In another example, TRP configuration component 342 can indicate in the instruction the identifier(s) of the TRPs that will be in the active set of UE 104, and can rely on UE 104 to determine which TRPs to activate and / or deactivate by comparing with the current set. As described above, TRP configuration component 342 can use various signaling possibilities to indicate the instruction (e.g., RRC signaling, MAC-CE, DCI, etc., as described herein).

[0090] In one example, in the transmitted instruction of block 506, optionally in block 508, the instruction may be transmitted to switch the BWP. In one aspect, the BWP switching configuration component 352 (e.g., in combination with the processor(s) 312, the memory 316, the transceiver 302, the TRP configuration component 342, etc.) may transmit the instruction to switch the BWP. For example, the BWP switching configuration component 352 may transmit the instruction in a BWP switching command (which may be sent via the DCI). As described, different BWPs may be associated with different TRPs and / or may be independently associated with a multi-TRP configuration or a single TRP configuration. In another example, as described, the command for switching the BWP may include an indication of whether the BWP is for multi-TRP operation or for single TRP operation. In any case, the BWP switching configuration component 352 may indicate a BWP switch to indicate a switch to multi-TRP operation or single TRP operation, or to a different TRP set than the current set containing the TRP(s). In one example, the BWP may implicitly identify the TRP with which the UE 104 is to communicate, as described.

[0091] For example, in method 500, optionally at block 510, a configuration of a BWP and an associated TRP may be transmitted. In one aspect, BWP switching configuration component 352 (e.g., in combination with processor(s) 312, memory 316, transceiver 302, TRP configuration component 342, etc.) may transmit a configuration of a BWP and an associated TRP. For example, as described, the configuration of a BWP may indicate an identifier of the BWP and also indicate associated TRP(s) (which may include indicating an identifier of the associated TRP(s)). In this example, BWP switching configuration component 342 may transmit the configuration of the BWP and the associated TRP to one or more UEs (e.g., UE 104), which may include transmitting using RRC signaling, MAC-CE, etc. In transmitting the instruction to switch the BWP at block 508, BWP switching configuration component 352 may transmit an identifier of the BWP to switch to, which may facilitate UE 104 to identify the associated TRP(s) via the received configuration. In this example, BWP switching configuration component 352 can transmit the instruction to switch the BWP in a DCI, as described.

[0092] In one example, in the transmission instruction of box 506, optionally in box 512, a DCI having one or more parameters indicating the instruction may be transmitted. In one aspect, the TRP configuration component 342 (e.g., in combination with the processor(s) 312, the memory 316, the transceiver 302, etc.) may transmit a DCI having one or more parameters indicating the instruction. For example, as described, the TRP configuration component 342 may utilize the TCI state in the DCI to indicate a single TRP operation or a multi-TRP operation (e.g., based on one or more QCL relationships associated with the TCI state). Moreover, as described, the base station 102 may configure the initial TCI state, the corresponding QCL relationship, etc. via RRC / MAC-CE scheduling, and the DCI may be used to dynamically modify the TCI state, select the QCL relationship, etc., to also modify whether to enable single TRP operation or enable multi-TRP operation, modify the list of TRPs to communicate with, etc. In one example, the QCL relationship may implicitly identify the TRP with which the UE 104 is to communicate, as described.

[0093] In any case, UE 104 may communicate using a set of one or more TRPs based on the transmitted instructions, for example, as described.

[0094] Figure 6 1 is a block diagram of a MIMO communication system 600 including a base station 102 and a UE 104. The MIMO communication system 600 may be explained with reference to Figure 1 The base station 102 may be a base station 102. Figure 1 6 and 653. In the MIMO communication system 600, the base station 102 may be capable of transmitting data on multiple communication links simultaneously. Each communication link may be referred to as a "layer", and the "rank" of the communication link may indicate the number of layers used for communication. For example, in a 2x2 MIMO communication system in which the base station 102 transmits two "layers", the rank of the communication link between the base station 102 and the UE 104 is 2.

[0095] At the base station 102, a transmit (Tx) processor 620 may receive data from a data source. The transmit processor 620 may process the data. The transmit processor 620 may also generate a control symbol or a reference symbol. The transmit MIMO processor 630 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, or reference symbols, where applicable, and may provide an output symbol stream to transmit modulators / demodulators 632 and 633. Each modulator / demodulator 632 to 633 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator / demodulator 632 to 633 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a DL signal. In one example, the DL signals from modulators / demodulators 632 and 633 may be transmitted via antennas 634 and 635, respectively.

[0096] UE 104 may be a reference Figure 1-2 Examples of various aspects of the UE 104 described herein. At the UE 104, the UE antennas 652 and 653 may receive DL signals from the base station 102 and may provide the received signals to the modulators / demodulators 654 and 655, respectively. Each modulator / demodulator 654 to 655 may condition (e.g., filter, amplify, downconvert, and digitize) the respective received signals to obtain input samples. Each modulator / demodulator 654 to 655 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 656 may obtain the received symbols from the modulators / demodulators 654 and 655, perform MIMO detection on the received symbols where applicable, and provide detected symbols. The receive (Rx) processor 658 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide the decoded data for the UE 104 to the data output, and provide the decoded control information to the processor 680 or the memory 682.

[0097] Processor 680 may, in some cases, execute stored instructions to instantiate communication component 242 (eg, see Figure 1 and 2 ).

[0098] On the uplink (UL), at the UE 104, a transmit processor 664 may receive and process data from a data source. The transmit processor 664 may also generate reference symbols for a reference signal. The symbols from the transmit processor 664 may be precoded by a transmit MIMO processor 666, if applicable, further processed by modulators / demodulators 654 and 655 (e.g., for SC-FDMA, etc.), and transmitted to the base station 102 according to the communication parameters received from the base station 102. At the base station 102, the UL signal from the UE 104 may be received by antennas 634 and 635, processed by modulators / demodulators 632 and 633, detected by a MIMO detector 636, if applicable, and further processed by a receive processor 638. The receive processor 638 may provide decoded data to a data output and to the processor 640 or memory 642.

[0099] In some cases, processor 640 may execute stored instructions to instantiate TRP configuration component 342 (see, e.g., Figure 1 and 3 ).
