Description

Technical Field

[0001]

[0013] Generally speaking, aspects of the present disclosure relate to wireless communications and the like. Background Art

[0002] Wireless communication systems have evolved over several generations, including first generation analog wireless telephone service (1G), second generation (2G) digital wireless telephone service (including temporary 2.5G networks), third generation (3G) high speed data, wireless service with Internet capabilities, and fourth generation (4G) services (e.g., Long Term Evolution (LTE), WiMax). There are many different types of wireless communication systems in use today, including cellular and personal communications service (PCS) systems. Examples of known cellular systems include the cellular analog Advanced Mobile Phone System (AMPS), and digital cellular systems based on code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), global system for mobile access (GSM) variations of TDMA, and the like.

[0003] The fifth generation (5G) mobile standard requires higher data transmission speeds, a larger number of connections and better coverage, among other improvements. According to the Next Generation Mobile Network Alliance, the 5G standard (also known as "New Radio" or "NR") is designed to provide data rates of tens of megabits per second to each of the tens of thousands of users and 1 gigabit per second to dozens of workers in an office floor. Hundreds of thousands of simultaneous connections should be supported to support large sensor deployments. Therefore, the spectral efficiency of 5G mobile communications should be significantly enhanced compared to the current 4G / LTE standards. In addition, signaling efficiency should be enhanced and latency should be greatly reduced compared to current standards. Summary of the invention

[0025] Various aspects of the present disclosure are provided in the following description and in the related drawings relating to various examples provided for illustrative purposes. Alternative aspects may be designed without departing from the scope of the present disclosure. In addition, well-known elements of the present disclosure will not be described in detail or omitted so as not to obscure the relevant details of the present disclosure.

[0026] The words "exemplary" and / or "example" are used herein to mean "serving as an example, instance, or illustration." Any aspect described herein as "exemplary" and / or "example" is not necessarily to be construed as preferred or advantageous over other aspects. Likewise, the term "aspects of the disclosure" does not require that all aspects of the disclosure include the discussed feature, advantage, or mode of operation.

[0027] Those skilled in the art will appreciate that any of a variety of different techniques and methods may be used to represent the information and signals described below. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the following description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof, depending in part on the specific application, in part on the desired design, in part on the corresponding technology, and so on.

[0028] In addition, many aspects are described in terms of sequences of actions to be performed by, for example, elements of a computing device. It will be appreciated that the various actions described herein may be performed by specific circuits (e.g., application specific integrated circuits (ASICs)), program instructions executed by one or more processors, or by a combination of the two. In addition, these sequences of actions described herein may be considered to be fully embodied in any form of non-transitory computer-readable storage medium having a corresponding set of computer instructions stored therein, which, when executed, will cause or instruct the associated processor of the device to perform the functions described herein. Therefore, various aspects of the present disclosure may be embodied in a variety of different forms, all of which are contemplated to be within the scope of the claimed subject matter. In addition, for each of the various aspects described herein, the corresponding form of any such aspect may be described herein as, for example, "logic configured to perform the described actions."

[0029] As used herein, unless otherwise specified, the terms "user equipment" (UE) and "base station" are not intended to be specific or otherwise limited to any specific radio access technology (RAT). In general, a UE can be any wireless communication device (e.g., a mobile phone, a router, a tablet computer, a laptop computer, a tracking device, a wearable device (e.g., a smart watch, glasses, augmented reality (AR) / virtual reality (VR) headsets, etc.), a vehicle (e.g., a car, a motorcycle, a bicycle, etc.), an Internet of Things (IoT) device, etc.) that can be used by a user to communicate on a wireless communication network. The UE can be mobile or can be stationary (e.g., at certain times) and can communicate with a radio access network (RAN). As used herein, the term "UE" can be interchangeably referred to as an "access terminal" or "AT", "client device", "wireless device", "subscriber equipment", "subscriber terminal", "subscriber station", "user terminal" or UT, "mobile terminal", "mobile station" or variations thereof. In general, a UE can communicate with a core network via a RAN, and through the core network, the UE can connect to external networks such as the Internet and to other UEs. Of course, other mechanisms for the UE to connect to the core network and / or the Internet are also possible, such as over a wired access network, a wireless local area network (WLAN) network (eg, based on IEEE 802.11, etc.), and so on.

[0030] A base station may operate according to one of several RATs to communicate with a UE (depending on the network in which the base station is deployed), and may alternatively be referred to as an access point (AP), a network node, a Node B, an evolved Node B (eNB), a new radio (NR) Node B (also referred to as a gNB or gNodeB), etc. In addition, in some systems, a base station may provide a pure edge node signaling function, while in other systems it may provide additional control and / or network management functions. The communication link through which a UE may send a signal to a base station is referred to as an uplink (UL) channel (e.g., a reverse traffic channel, a reverse control channel, an access channel, etc.).

[0031] The communication link through which the base station can send signals to the UE is called a downlink (DL) or forward link channel (e.g., a paging channel, a control channel, a broadcast channel, a forward traffic channel, etc.). As used herein, the term traffic channel (TCH) can refer to a UL / reverse traffic channel or a DL / forward traffic channel.

[0032] The term "base station" may refer to a single physical transmission point or to multiple physical transmission points that may or may not be co-located. For example, where the term "base station" refers to a single physical transmission point, the physical transmission point may be an antenna of the base station corresponding to a cell of the base station. Where the term "base station" refers to multiple co-located physical transmission points, the physical transmission point may be an antenna array of the base station (e.g., as in a multiple-input multiple-output (MIMO) system or where the base station employs beamforming). Where the term "base station" refers to multiple non-co-located physical transmission points, the physical transmission point may be a distributed antenna system (DAS) (a network of spatially separated antennas connected to a common source via a transmission medium) or a remote radio head (RRH) (a remote base station connected to a serving base station). Alternatively, the non-co-located physical transmission point may be a serving base station that receives a measurement report from a UE and a neighbor base station whose reference RF signal the UE is measuring.

[0033] Figure 1 An exemplary wireless communication system 100 is shown. The wireless communication system 100 (which may also be referred to as a wireless wide area network (WWAN)) may include various base stations 102 and various UEs 104. The base stations 102 may include macrocell base stations (high-power cellular base stations) and / or small cell base stations (low-power cellular base stations). In one aspect, the macrocell base stations may include eNBs (where the wireless communication system 100 corresponds to an LTE network) or gNBs (where the wireless communication system 100 corresponds to a 5G network) or a combination of both, and the small cell base stations may include femtocells, picocells, microcells, etc.

[0034] The base stations 102 may collectively form a RAN and interface with a core network 170 (e.g., an evolved packet core (EPC) or a next generation core (NGC)) through a backhaul link 122, or interface with one or more location servers 172 through the core network 170. The base stations 102 may perform, among other functions, functions related to one or more of the following: transmission 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, RAN sharing, multimedia broadcast multicast service (MBMS), subscriber and device tracking, RAN information management (RIM), paging, positioning, and transmission of warning messages. The base stations 102 may communicate with each other directly or indirectly (e.g., through EPC / NGC) through a backhaul link 134, which may be wired or wireless.

[0035] The base station 102 can communicate with the UE 104 wirelessly. Each of the base stations 102 can provide communication coverage for the corresponding geographic coverage area 110. In one aspect, one or more cells can be supported by the base station 102 in each coverage area 110. A "cell" is a logical communication entity used to communicate with a base station (e.g., on a certain frequency resource (referred to as a carrier frequency, component carrier, carrier, frequency band, etc.)), and can be associated with a cell identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID)) used to distinguish between cells operating via the same or different carrier frequencies. In some cases, different cells can be configured according to different protocol types (e.g., machine type communication (MTC), narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB) or other protocol types) that can provide access to different types of UEs. In some cases, the term "cell" can also refer to a geographic coverage area (e.g., a sector) of a base station, within which a carrier frequency can be detected and used for communication within a certain portion of the geographic coverage area 110.

[0036] Although the geographic coverage areas 110 of adjacent macrocell base stations 102 may partially overlap (e.g., in a handoff region), some of the geographic coverage areas 110 may substantially overlap with the larger geographic coverage areas 110. For example, a small cell base station 102' may have a coverage area 110' that substantially overlaps with the coverage areas 110 of one or more macrocell base stations 102. A network that includes both small cell base stations and macrocell base stations may be referred to as a heterogeneous network. A heterogeneous network may also include a home eNB (HeNB), which may provide services to a restricted group referred to as a closed subscriber group (CSG).

[0037] The communication link 120 between the base station 102 and the UE 104 may include UL (also referred to as a reverse link) transmissions from the UE 104 to the base station 102 and / or downlink (DL) (also referred to as a forward link) transmissions from the base station 102 to the UE 104. The communication link 120 may use MIMO antenna technology, which may include spatial multiplexing, beamforming, and / or transmit diversity. The communication link 120 may be over one or more carrier frequencies. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​than for UL).

[0038] The wireless communication system 100 may also include a wireless local area network (WLAN) access point (AP) 150 that communicates with a WLAN station (STA) 152 in an unlicensed spectrum (e.g., 5 GHz) via a communication link 154. When communicating in the unlicensed spectrum, the WLAN STA 152 and / or the WLAN AP 150 may perform a clear channel assessment (CCA) before communicating to determine whether a channel is available.

[0039] The small cell base station 102' can operate in a licensed and / or unlicensed spectrum. When operating in an unlicensed spectrum, the small cell base station 102' can employ LTE or 5G technology and use the same 5 GHz unlicensed spectrum as the 5 GHz unlicensed spectrum used by the WLAN AP 150. The small cell base station 102' employing LTE / 5G in the unlicensed spectrum can improve coverage of the access network and / or increase the capacity of the access network. LTE in the unlicensed spectrum can be referred to as LTE Unlicensed (LTE-U), License Assisted Access (LAA), or MulteFire.

[0040] The wireless communication system 100 may also include a millimeter wave (mmW) base station 180, which can operate in mmW frequencies and / or near mmW frequencies to communicate with UE 182. Extremely high frequency (EHF) is a part of RF in the electromagnetic spectrum. EHF has a range of 30 GHz to 300 GHz and has a wavelength between 1 mm and 10 mm. The radio waves in this band can be called millimeter waves. Near mmW can be extended down to a frequency of 3 GHz with a wavelength of 100 mm. The super high frequency (SHF) band extends between 3 GHz and 30 GHz and is also called centimeter waves. Communication using mmW / near mmW radio frequency bands has high path loss and relatively short distances. The mmW base station 180 and the UE 182 can utilize beamforming (transmitting and / or receiving) on ​​the mmW communication link 184 to compensate for the extremely high path loss and short distance. In addition, it will be appreciated that in an alternative configuration, one or more base stations 102 can also use mmW or near mmW and beamforming to transmit. Accordingly, it will be appreciated that the foregoing description is merely exemplary and should not be construed as limiting the various aspects disclosed herein.

[0041] Transmit beamforming is a technique for focusing an RF signal in a specific direction. Traditionally, when a network node (e.g., a base station) broadcasts an RF signal, it broadcasts the signal in all directions (omnidirectionally). With transmit beamforming, the network node determines the location of a given target device (e.g., a UE) (relative to the transmitting network node) and projects a stronger downlink RF signal in that specific direction, thereby providing a faster (in terms of data rate) and stronger RF signal to the receiving device. In order to change the directionality of the RF signal when transmitting, the network node can control the phase and relative amplitude of the RF signal at each of the one or more transmitters that broadcast the RF signal. For example, the network node can use an array of antennas (also known as a "phased array" or "antenna array") that creates a beam of RF waveform, where the beam can be "controlled" to point in different directions without actually moving the antenna. Specifically, the RF current from the transmitter is fed to each antenna with the correct phase relationship so that the radio waves from the individual antennas are added together to increase the radiation in the desired direction, while canceling to suppress the radiation in the undesired direction.

[0042] In receive beamforming, a receiver uses a receive beam to amplify an RF signal detected on a given channel. For example, a receiver may increase the gain setting and / or adjust the phase setting of an antenna array in a particular direction to amplify the RF signal received from that direction (e.g., increase the gain level of the RF signal received from that direction). Thus, when a receiver is referred to as performing beamforming in a certain direction, this means that the beam gain in that direction is high relative to the beam gain along other directions, or that the beam gain in that direction is the highest compared to the beam gain in that direction of all other receive beams available to the receiver. This results in a stronger received signal strength (e.g., reference signal received power (RSRP), reference signal received quality (RSRQ), signal to interference plus noise ratio (SINR), etc.) of the RF signal received from that direction.

[0043] In 5G, the spectrum in which wireless nodes (e.g., base stations 102 / 180, UEs 104 / 182) operate is divided into multiple frequency ranges: FR1 (from 450 to 6000 MHz), FR2 (from 24250 to 52600 MHz), FR3 (above 52600 MHz), and FR4 (between FR1 and FR2). In a multi-carrier system such as 5G, one of the carrier frequencies is referred to as the "primary carrier" or "anchor carrier" or "primary serving cell" or "PCell", and the remaining carrier frequencies are referred to as "secondary carriers" or "secondary serving cells" or "SCells". In carrier aggregation, the anchor carrier is a carrier operating on the primary frequency (e.g., FR1) utilized by the UE 104 / 182 and the cell in which the UE 104 / 182 performs an initial radio resource control (RRC) connection establishment procedure or initiates an RRC connection re-establishment procedure. The primary carrier carries all common and UE-specific control channels. A secondary carrier is a carrier operating on a second frequency (e.g., FR2), which can be configured once an RRC connection is established between the UE 104 and the anchor carrier, and which can be used to provide additional radio resources. The secondary carrier may contain only necessary signaling information and signals, for example, there may be no UE-specific signaling information and signals in the secondary carrier, because both the primary uplink and downlink carriers are typically UE-specific. This means that different UEs 104 / 182 in a cell can have different downlink primary carriers. The same is true for the uplink primary carrier. The network is able to change the primary carrier of any UE 104 / 182 at any time. For example, this is done to balance the load on different carriers. Because a "serving cell" (whether a PCell or an SCell) corresponds to a carrier frequency / component carrier on which a base station is communicating, the terms "cell", "serving cell", "component carrier", "carrier frequency", etc. can be used interchangeably.

[0044] For example, still referring to Figure 1 , one of the frequencies utilized by the macrocell base station 102 may be an anchor carrier (or "PCell"), and the other frequencies utilized by the macrocell base station 102 and / or the mmW base station 180 may be secondary carriers ("SCells"). Simultaneous transmission and / or reception of multiple carriers enables the UE 104 / 182 to significantly increase its data transmission and / or reception rate. For example, in theory, two 20 MHz aggregated carriers in a multi-carrier system would result in a two-fold increase in data rate (i.e., 40 MHz) compared to the data rate obtained by a single 20 MHz carrier.

[0045] The wireless communication system 100 may also include one or more UEs (eg, UE 190) indirectly connected to one or more communication networks via one or more device-to-device (D2D) or peer-to-peer (P2P) links. Figure 1 In the example of FIG. 1 , UE 190 has a D2D P2P link 192 with one of UEs 104 connected to one of base stations 102 (e.g., through D2D P2P link 192, UE 190 can indirectly obtain cellular connectivity) and a D2D P2P link 194 with WLAN STA 152 connected to WLAN AP 150 (e.g., through D2D P2P link 194, UE 190 can indirectly obtain WLAN-based Internet connectivity). In one example, any well-known D2D RAT (e.g., LTE Direct (LTE-D), WiFi Direct (WiFi-D), etc.) to support D2D P2P links 192 and 194.

[0046] The wireless communication system 100 may also include a UE 164 that may communicate with the macrocell base station 102 over the communication link 120 and / or with the mmW base station 180 over the mmW communication link 184. For example, the macrocell base station 102 may support a PCell and one or more Scells for the UE 164, and the mmW base station 180 may support one or more Scells for the UE 164. In one aspect, the UE 164 may include a MAC-CE manager 166 that may enable the UE 164 to perform the UE operations described herein. Note that although Figure 1 Only one UE is shown as having a MAC-CE manager 166, but Figure 1 Any UE in the may be configured to perform the UE operations described herein.

[0047] Figure 2AAn example wireless network architecture 200 is shown. For example, the NGC 210 (also referred to as "5GC") can be functionally considered as a control plane functional unit 214 (e.g., UE registration, authentication, network access, gateway selection, etc.) and a user plane functional unit 212 (e.g., UE gateway function, access to data network, IP routing, etc.), which operate cooperatively to form a core network. The user plane interface (NG-U) 213 and the control plane interface (NG-C) 215 connect the gNB 222 to the NGC 210, and specifically, to the control plane functional unit 214 and the user plane functional unit 212. In additional configurations, the eNB 224 can also be connected to the NGC 210 via the NG-C 215 to the control plane functional unit 214 and the NG-U 213 to the user plane functional unit 212. In addition, the eNB 224 can communicate directly with the gNB 222 via the backhaul connection 223. In some configurations, the new RAN 220 may have only one or more gNBs 222, while other configurations include one or more of both eNBs 224 and gNBs 222. The gNB 222 or the eNB 224 may communicate with the UE 204 (e.g., Figure 1 204). Another optional aspect may include one or more location servers 230a, 230b (sometimes collectively referred to as location servers 230 (which may correspond to location server 172)), which may communicate with control plane functional unit 214 and user plane functional unit 212 in NGC 210, respectively, to provide location assistance to UE 204. Location server 230 may be implemented as multiple separate servers (e.g., physically separate servers, different software modules on a single server, different software modules distributed on multiple physical servers, etc.), or alternatively, may correspond to a single server, respectively. Location server 230 may be configured to support one or more location services for UE 204 that may be connected to location server 230 via the core network, NGC 210, and / or via the Internet (not shown). In addition, location server 230 may be integrated into a component of the core network, or alternatively, may be external to the core network (e.g., in new RAN 220).

[0048] Figure 2BAnother example wireless network structure 250 is shown. For example, the NGC 260 (also referred to as "5GC") can be functionally viewed as a control plane functional unit provided by the access and mobility management function unit (AMF) 264, the user plane function unit (UPF) 262, the session management function unit (SMF) 266, the SLP 268, and the LMF 270, which operate in conjunction to form the core network (i.e., NGC 260). The user plane interface 263 and the control plane interface 265 connect the ng-eNB 224 to the NGC 260 and specifically to the UPF 262 and the AMF 264, respectively. In additional configurations, the gNB 222 can also be connected to the NGC 260 via the control plane interface 265 to the AMF 264 and the user plane interface 263 to the UPF 262. In addition, the eNB 224 can communicate directly with the gNB 222 via the backhaul connection 223 (with or without gNB direct connectivity to the NGC 260). In some configurations, the new RAN 220 may have only one or more gNBs 222, while other configurations include one or more of both ng-eNB 224 and gNB 222. The Ng-gNB 222 or the eNB 224 can communicate with the UE 204 (e.g., Figure 1 The base stations of the new RAN 220 communicate with the AMF 264 over the N2 interface and with the UPF 262 over the N3 interface.

[0049] The functions of AMF include registration management, connection management, reachability management, mobility management, lawful interception, transmission of session management (SM) messages between UE 204 and SMF 266, transparent proxy service for routing SM messages, access authentication and access authorization, transmission of short message service (SMS) messages between UE 204 and short message service function unit (SMSF) (not shown), and security anchor function unit (SEAF). AMF also interacts with authentication server function (AUSF) (not shown) and UE 204, and receives intermediate keys established as a result of the UE 204 authentication process. In the case of authentication based on UMTS (Universal Mobile Telecommunications System) User Identity Module (USIM), AMF retrieves security materials from AUSF. The functions of AMF also include security context management (SCM). SCM receives keys from SEFA, which SCM uses to derive keys specific to the access network. The functions of AMF also include location service management for supervising services, transmission of location service messages between UE 204 and location management function unit (LMF) 270 (which may correspond to location server 172) and between new RAN 220 and LMF 270, allocation of Evolved Packet System (EPS) bearer identifiers for interworking with EPS, and notification of mobility events of UE 204. In addition, AMF also supports the functions of non-3rd Generation Partnership Project (3GPP) access networks.

[0050] The functions of the UPF include: acting as an anchor point for intra / inter-RAT mobility (if applicable), acting as an external protocol data unit (PDU) session point for interconnection to a data network (not shown), providing packet routing and forwarding, packet inspection, user plane policy rule enforcement (e.g., gating, redirection, service steering), lawful interception (user plane collection), service usage reporting, quality of service (QoS) processing for the user plane (e.g., UL / DL rate enforcement, reflective QoS marking in DL), UL service verification (service data flow (SDF) to QoS flow mapping), transport level packet marking in UL and DL, DL packet buffering and DL data notification triggering, and sending and forwarding one or more "end markers" to the source RAN node.

[0051] The functions of SMF 266 include session management, UE Internet Protocol (IP) address allocation and management, selection and control of user plane functions, configuration of service steering at UPF to route services to appropriate destinations, control of policy enforcement and parts of QoS, and downlink data notification. The interface over which SMF 266 communicates with AMF 264 is called the N11 interface.

[0052] Another optional aspect may include LMF 270, which can communicate with NGC 260 to provide location assistance to UE 204. LMF 270 can be implemented as multiple separate servers (e.g., physically separate servers, different software modules on a single server, different software modules distributed on multiple physical servers, etc.), or alternatively, can correspond to a single server respectively. LMF 270 can be configured to support one or more positioning services for UE 204, and UE 204 can be connected to LMF 270 via the core network, NGC 260 and / or via the Internet (not shown).

[0053] Figure 3 Base station 102 and UE 104 (which may be Figure 1 1. Block diagram of a design 300 of a base station 102 and a UE 104. Base station 102 may be equipped with T antennas 334a through 334t, and UE 104 may be equipped with R antennas 352a through 352r, where in general, T≥1 and R≥1.

[0054] At the base station 102, the transmit processor 320 may receive data for one or more UEs from the data source 312, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 320 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 320 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 330 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 332a to 332t. Each modulator 332 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 332 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 332a to 332t may be transmitted via T antennas 334a to 334t, respectively. According to various aspects described in more detail below, synchronization signals may be generated using position coding to convey additional information.

[0055] At the UE 104, antennas 352a to 352r can receive downlink signals from the base station 102 and / or other base stations, and can provide received signals to demodulators (DEMOD) 354a to 354r, respectively. Each demodulator 354 can condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 354 can further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 356 can obtain received symbols from all R demodulators 354a to 354r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. The receive processor 358 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 104 to the data sink 360, and provide decoded control information and system information to the controller / processor 380. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 104 may be included in a housing.

[0056] On the uplink, at the UE 104, a transmit processor 364 may receive and process data from a data source 362 and control information from a controller / processor 380 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 364 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 364 may be precoded by a TX MIMO processor 366 (if applicable), further processed by modulators 354a through 354r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 102. At the base station 102, uplink signals from the UE 104 and other UEs may be received by the antenna 334, processed by the demodulator 332, detected by the MIMO detector 336 (if applicable), and further processed by the receive processor 338 to obtain decoded data and control information transmitted by the UE 104. The receive processor 338 may provide decoded data to a data sink 339 and decoded control information to a controller / processor 340. The base station 102 may include a communication unit 344 and communicate with a network controller 389 via the communication unit 344. The network controller 389 may include a communication unit 394, a controller / processor 390, and a memory 392.

[0057] The controller / processor 340 of the base station 102, the controller / processor 380 of the UE 104, and / or Figure 3 Any other components of the base station 102 may perform one or more techniques associated with using a single MAC-CE to activate or deactivate reception of multiple DL PRSs and / or transmission of multiple UL PRSs in the UE 104, as described in more detail elsewhere herein. For example, the controller / processor 340 of the base station 102, the controller / processor 380 of the UE 104, and / or Figure 3 Any other component may perform or direct e.g. Fig.15 The process of 1500 Fig.16 The operations of the process 1600 and / or other processes as described herein. The memories 342 and 382 may store data and program codes for the base station 102 and the UE 104, respectively. In some aspects, the memory 342 and / or the memory 382 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, when the one or more instructions are executed by one or more processors of the base station 102 and / or the UE 104, the execution or guidance of the instructions may be performed, for example, Fig.15 The process of 1500 Fig.16 The scheduler 346 may schedule UEs for data transmission on the downlink and / or uplink.

[0058] As pointed out above, Figure 3 is provided as an example. Other examples may differ from those described above. Figure 3 An example of description.

[0059] Figure 4 The structure of an exemplary subframe sequence 400 with positioning reference signal (PRS) positioning opportunities according to aspects of the present disclosure is shown. The subframe sequence 400 may be suitable for broadcasting PRS signals from a base station (e.g., any base station described herein) or other network node. The subframe sequence 400 may be used in an LTE system, and the same or similar subframe sequences may be used in other communication technologies / protocols (such as 5G and NR). Figure 4 In FIG. 1 , time is represented horizontally (e.g., on the X-axis), where time increases from left to right, and frequency is represented vertically (e.g., on the Y-axis), where frequency increases (or decreases) from bottom to top. Figure 4 As shown, the downlink and uplink radio frames 410 may each have a duration of 10 milliseconds (ms). For a downlink frequency division duplex (FDD) mode, in the example shown, the radio frame 410 is organized into ten subframes 412 each having a duration of 1 ms. Each subframe 412 includes two time slots 414, each time slot 414 having, for example, a duration of 0.5 ms.

[0060] In the frequency domain, the available bandwidth may be divided into uniformly spaced orthogonal subcarriers 416 (also referred to as "tones" or "bins"). For example, for a normal length cyclic prefix (CP) using, for example, 15 kHz spacing, the subcarriers 416 may be grouped into groups of twelve (12) subcarriers. A resource (represented as a block of subframes 412) having a length of one OFDM symbol in the time domain and one subcarrier in the frequency domain is referred to as a resource element (RE). Each group of 12 subcarriers 416 and 14 OFDM symbols is referred to as a resource block (RB), and in the example above, the number of subcarriers in a resource block may be written as For a given channel bandwidth, the number of available resource blocks on each channel 422 (also referred to as a transmission bandwidth configuration 422) is indicated as For example, for the 3 MHz channel bandwidth in the above example, the number of available resource blocks on each channel 422 is given by Note that the frequency components of a resource block (eg, 12 subcarriers) are called physical resource blocks (PRBs).

[0061] The base station can Figure 4 The frame configuration shown is similar or the same as the frame configuration to transmit a radio frame (e.g., radio frame 410) or other physical layer signaling sequence supporting a PRS signal (i.e., a downlink (DL) PRS) that can be measured and used for UE (e.g., any UE described herein) position estimation. Other types of wireless nodes in the wireless communication network (e.g., distributed antenna systems (DAS), remote radio heads (RRH), UEs, APs, etc.) can also be configured to transmit to communicate with Figure 4 A PRS signal configured in a manner similar to (or identical to) that depicted in .

[0062] A set of resource elements used for transmission of a PRS signal is referred to as a "PRS resource". A set of resource elements may span multiple PRBs in the frequency domain and N (e.g., 1 or more) consecutive symbols within a slot 414 in the time domain. For example, a cross-hatched resource element in a slot 414 may be an example of two PRS resources. A "PRS resource set" is a set of PRS resources used for transmission of a PRS signal, where each PRS resource has a PRS resource identifier (ID). In addition, the PRS resources in a PRS resource set are associated with the same transmit receive point (TRP). The PRS resource ID in a PRS resource set is associated with a single beam transmitted from a single TRP (wherein a TRP may transmit one or more beams). Note that this does not have any implication as to whether the UE knows the TRP and beam from which the signal is transmitted.

[0063] PRS may be sent in special positioning subframes grouped into positioning opportunities. A PRS opportunity is an example of a periodically repeated time window (e.g., consecutive time slots) in which PRS is expected to be sent. Each periodically repeated time window may include a group of one or more consecutive PRS opportunities. Each PRS opportunity may include N PRS The PRS positioning opportunities of the cells supported by the base station may occur periodically at an interval determined by T PRS As an example, Figure 4 shows the period of positioning opportunity, where N PRS is equal to 4 418 and T PRS Greater than or equal to 20420. In some aspects, T may be measured as the number of subframes between the start of consecutive positioning opportunities. PRS Multiple PRS opportunities may be associated with the same PRS resource configuration, in which case each such opportunity is referred to as an "opportunity of the PRS resource" or the like.

[0064] PRS can be sent at constant power. PRS can also be sent at zero power (i.e., muted). When PRS signals between different cells overlap by occurring simultaneously or almost simultaneously, muting (which turns off regularly scheduled PRS transmissions) may be useful. In this case, PRS signals from some cells can be muted, while PRS signals from other cells are sent (e.g., at constant power). Muting can assist UEs in signal acquisition and arrival time (TOA) and reference signal time difference (RSTD) measurements of unmuted PRS signals (by avoiding interference from muted PRS signals). Muting can be considered as not transmitting PRS within a given positioning opportunity for a particular cell. A muting mode (also referred to as a muting sequence) can be signaled to the UE using a bit string (e.g., using the LTE Positioning Protocol (LPP)). For example, in a bit string signaled to indicate a muting mode, if the bit at position j is set to "0", the UE can infer that the PRS is muted within the jth positioning opportunity.

[0065] To further improve the audibility of the PRS, the positioning subframe can be a low-interference subframe transmitted without a user data channel. Therefore, in an ideal synchronized network, the PRS may be interfered by the PRS of other cells with the same PRS pattern index (i.e., with the same frequency offset), but not by data transmission. The frequency offset can be defined as the PRS ID of the cell or other transmission point (TP) (denoted as ), or in the case where no PRS ID is assigned, is defined as a physical cell identifier (PCI) (denoted as ), which results in an effective frequency reuse factor of six (6).

[0066] To also improve the audibility of the PRS (e.g., when the PRS bandwidth is limited, such as having only six resource blocks corresponding to a 1.4 MHz bandwidth), the frequency band used for consecutive PRS positioning occasions (or consecutive PRS subframes) may be changed in a known and predictable manner via frequency hopping. In addition, a cell supported by a base station may support more than one PRS configuration, wherein each PRS configuration may include a different frequency offset (vshift), a different carrier frequency, a different bandwidth, a different code sequence, and / or a different sequence of PRS positioning occasions, wherein each positioning occasion has a specific number of subframes (N PRS ) and a specific period (T PRS ). In some implementations, one or more of the PRS configurations supported in a cell may be for directional PRS and may then have additional different characteristics, such as different transmission directions, different horizontal angle ranges, and / or different vertical angle ranges.

[0067] As described above, the PRS configuration including the PRS transmission / muting schedule is signaled to the UE to enable the UE to perform PRS positioning measurements. It is not desirable for the UE to blindly perform detection of the PRS configuration.

[0068] Note that the terms "positioning reference signal" and "PRS" may sometimes refer to a specific reference signal used for positioning in an LTE system. However, as used herein, unless otherwise indicated, the terms "positioning reference signal" and "PRS" refer to any type of reference signal that may be used for positioning, such as, but not limited to: PRS signals in LTE, navigation reference signals (NRS), transmitter reference signals (TRS), cell-specific reference signals (CRS), channel state information reference signals (CSI-RS), primary synchronization signals (PSS), secondary synchronization signals (SSS), etc.

[0069] Similar to the DL PRS sent by the base station discussed above, the UE can send a UL PRS for positioning. The UL PRS can be, for example, a sounding reference signal (SRS) used for positioning. Using the DL PRS received from the base station and / or the UL PRS sent to the base station, the UE can perform various positioning methods, such as time of arrival (TOA), reference signal time difference (RSTD), time difference of arrival (TDOA), reference signal received power (RSRP), time difference between reception and transmission of a signal (Rx-Tx), angle of arrival (AoA) or angle of transmission (AoD), etc. In some implementations, the DL PRS and the UL PRS are jointly received and sent to perform multi-cell round trip time (M-RTT) positioning measurements.

[0070] As described above, the configuration of the DL PRS to be received is provided to the UE so that the UE can perform PRS positioning measurements. Similarly, the SRS-Config information element (IE) can be used to configure the UL PRS to be sent by the UE 104, for example, the SRS for positioning. The configuration is defined based on the bandwidth part (BWP) and defines an SRS resource list and an SRS resource set list. Each resource set defines an SRS resource set. Table 1 shows a fragment of Abstract Syntax Notation 1 (ASN.1), which shows the SRS configuration per BWP.

[0071]

[0072]

[0073] Table 1

[0074] Table 2 shows another fragment of ASN.1, which shows the interior of the configuration of SRS-Config, SRS resources and SRS resource sets.

[0075]

[0076] Table 2 and Table 3 show another fragment of ASN.1, which shows the configuration of SRS resources.

[0077]

[0078] Table 3 and Table 4 show another fragment of ASN.1, which shows the configuration of SRS SpatialRelationInfo.

[0079]

[0080] Table 4

[0081] Therefore, the RRC configuration of the SRS transmission setting uses the IE SRS-Config, which is configured according to the BWP and contains a list of SRS resources, where each SRS resource contains information on the physical mapping of the reference signal on the time-frequency resource grid, time domain information, a sequence identifier (ID), etc. SRS-Config contains a list of SRS resource sets, which contains a list of SRS resources.

[0082] Three types of SRS transmissions can be supported. Periodic SRS is sent periodically in certain time slots. This SRS transmission is semi-statically configured by RRC using parameters such as SRS resources, period, and slot offset. Aperiodic SRS is a single SRS transmission that can occur in any time slot. Here, single means that the SRS transmission occurs only once per trigger. Semi-persistent SRS (SP SRS) is similar to P SRS in that the resources used for SP SRS transmission are semi-statically configured with parameters such as period and slot offset. Dynamic signaling is used to activate and deactivate SP SRS transmission.

[0083] The transmission of the SRS may be activated or deactivated using a medium access control-control element (MAC-CE) within the UE 104. For example, the SRS used for positioning may have a semi-persistent configuration activated or deactivated using a MAC-CE and received by a serving base station and a neighboring base station. The SRS used for positioning may also be aperiodic, which may be activated or deactivated by downlink control information (DCI) communication.

[0084] For example, in the case of SP SRS, the base station 102 may first configure the UE 104 with SP SRS resources, and then use MAC-CE to activate or deactivate the SP SRS resource set.

[0085] A spatial relationship indication may be provided for an SRS resource. The spatial relationship may be, for example, a downlink reference signal (RS) (SSB or CSI-RS) or a previously transmitted SRS. For example, the spatial relationship may be used to indicate an uplink transmission beam that the UE 104 may use to precode the SRS. If the UE 104 is capable of beam correspondence, the uplink beam may be derived from a downlink beam management process and the spatial relationship to the downlink RS may be indicated, for example, where the UE 104 may send the SRS in the opposite direction of how it sets its receive beam when receiving the downlink RS. Alternatively, an uplink beam management process may be used where the UE 104 sends an SRS beam scan and the base station refers back to one of the scanned beams in a previously transmitted SRS resource to indicate a spatial relationship to the SRS resource.

[0086] Figure 5 By way of example, a MAC-CE block 500 for activating or deactivating a single semi-persistent (SP) SRS is shown. As shown, the MAC-CE block 500 includes the following fields.

[0087] The A / D field indicates whether the indicated SP SRS resource set is activated or deactivated. This field is set to 1 to indicate activation, otherwise it indicates deactivation.

[0088] The Cell ID field of the SRS resource set indicates the identity of the serving cell, which contains the activated / deactivated SP SRS resource set. If the C field is set to 0, this field also indicates the identity of the serving cell, which contains the resource ID i All resources indicated by the field. The length of this field is 5 bits.

[0089] The BWP ID field of the SRS resource set indicates the UL Bandwidth Part (BWP) as the code point of the DCI Bandwidth Part Indicator field as specified in 3GPP Technical Specification (TS) 38.212, which contains the activated / deactivated SP SRS resource set. If the C field is set to 0, this field also indicates the identity of the BWP, which contains the resource ID i All resources indicated by the field. The length of this field is 2 bits.

[0090] Therefore, the Cell ID of the SRS resource set and the BWP ID of the SRS resource set fields identify the serving cell and component carrier (CC) of the SP SRS, respectively, which is usually required because the SRS resource set ID is locally defined. Therefore, in order to uniquely identify the SRS resource set, the cell ID, BWP-ID and SRS resource set ID are required in the context of the serving cell and BWP of the CC.

[0091] The C field indicates whether there is an octet containing the resource serving cell ID field and the resource BWP ID field. If this field is set to 1, the octet containing the resource serving cell ID field and the resource BWP ID field is present, otherwise they are not present.

[0092] The SUL field indicates whether the MAC CE applies to a NUL carrier or a SUL carrier configuration. This field is set to 1 to indicate that it applies to a supplementary uplink (SUL) carrier configuration, and it is set to 0 to indicate that it applies to a normal uplink (NUL) carrier configuration;

[0093] The SP SRS Resource Set ID field indicates the SP SRS resource set ID identified by SRS-ResourceSetId as specified in 3GPP TS 38.331, which is to be activated or deactivated. The length of this field is 4 bits.

[0094] F iThe field indicates the type of resource used as the spatial relationship of the SRS resource within the SP SRS resource set indicated by the SP SRS resource set ID field. F0 refers to the first SRS resource within the resource set, F1 refers to the second SRS resource, and so on. This field is set to 1 to indicate that a non-zero power (NZP) channel state information reference signal (CSI-RS) resource index is used, and it is set to 0 to indicate that an SSB index or an SRS resource index is used. The length of this field is 1 bit. This field is only present if the MAC CE is used for activation (i.e., the A / D field is set to 1).

[0095] Resource ID i The field contains the identifier of the resource used for spatial relationship derivation of SRS resource i. Resource ID0 refers to the first SRS resource in the resource set, resource ID1 refers to the second SRS resource, and so on. i is set to 0, and the first bit of this field is set to 1, then the remainder of this field contains the Synchronization Signal Block (SSB)-Index as specified in 3GPP TS 38.331. i The A / D field is set to 1. If the A / D field is set to 0, and the first bit of this field is set to 0, the remainder of the field contains the SRS-ResourceId as specified in 3GPP TS 38.331. The length of this field is 7 bits. This field is only present if the MAC CE is used for activation (i.e., the A / D field is set to 1).

[0096] Resource service cell ID i The field indicates the identity of the serving cell in which the resource is located for spatial relationship derivation of SRS resource i. The length of this field is 5 bits. i The field is an indicator of the CC ID of the SRS or CSI-RS used for spatial relationship.

[0097] Resource BWP ID i The UL BWP field indicates the code point of the DCI bandwidth part indicator field as specified in 3GPP TS 38.212 on which the resource for spatial relation derivation of SRS resource i is located. The length of this field is 2 bits. Therefore, the resource BWP ID i This field is an indicator of the BWP ID of the SRS used for the spatial relationship.

[0098] The R field is a reserved bit and is set to 0.

[0099] F i Field and resource IDs iThe field provides spatial relationship information according to the SRS resource configuration. For example, for SRS used for positioning, the spatial relationship can come from SRS resources used for "communication" (Fi=0); SSB (Fi=0); or CSI-RS resources (Fi=1).

[0100] If the spatial relationship information indicates that the spatial relationship is from DL-PRS, the following parameters of DL-PRS may be provided in the UL-SRS for positioning configuration in the MAC-CE block. A DL-PRS ID may be provided, which may be associated with multiple DL-PRS resource sets associated with a single TRP. In addition, a DL PRS resource set ID and a DL PRS resource ID are provided.

[0101] DL PRS resources may be uniquely identified, for example, using an identity that may be associated with multiple DL PRS resource sets associated with a single TRP. This identity may be used together with a DL PRS resource set ID defined locally within a TRP and a DL PRS resource ID defined locally within a DL PRS resource set to uniquely identify a DL PRS resource. Each TRP may be associated with only one such identity.

[0102] Regarding DL-PRS quasi-colocation (QCL), for DL ​​PRS resources, QCL type-C (Doppler shift, average delay) from SSBs from TRPs can be supported. For positioning purposes, in order to assist the UE in performing receive (Rx) beamforming, the DL PRS can be configured with QCL type-D (spatial Rx parameters) of the DL reference signal from the serving cell or neighboring cell. SSB or DL-PRS can be the QCL type D source of DL-PRS. If the DL PRS QCL information of the DL-PRS resource of the TRP indicates "QCL type-D from DL-PRS resources", the DL-PRS resource set ID and DL-PRS-resource ID of the indicated source DL-PRS resource can be provided. The QCL relationship between two DL-PRS resources is provided only for DL-PRS resources of the same TRP. The SSB index indicated for the QCL type-D and QCL type-C of the DL-PRS resources may be the same.

[0103] If the spatial relationship information indicates that the spatial relationship is from an SRS resource, the following parameters of the SRS used for positioning may be provided: SRS resource ID, UL BWP ID, and serving cell ID.

[0104] The maximum number of supported SRS resource sets for positioning is based on UE capabilities, and up to 16 resource sets may be configured per BWP.

[0105] When a MAC CE for a set of CCs and / or BWPs activates or updates spatialRelationInfo for a semi-persistent or aperiodic SRS resource (where the applicable CC list is indicated by a higher layer parameter (e.g., applicableCellList), the spatialRelationInfo is applied to the semi-persistent or aperiodic SRS resources with the same SRS resource ID for all BWPs in the indicated CC.

[0106] The spatial relationship information that can be signaled for SP SRS can be summarized in Table 5.

[0107]

[0108] Table 5

[0109] It may be necessary to trigger multiple SRS resource sets to the UE. Each SRS resource set may have different Tx beam and / or power control parameters for optimized transmission from the UE to different subsets of TRPs. For example, up to 16 SRS resource sets per UE per BWP for positioning may be supported.

[0110] Current implementations contemplate separate MAC-CE commands for activating / deactivating each SRS resource set. However, multiple MAC-CE commands are not optimal in terms of overhead. In addition, high latency may be expected due to the high overhead. Similar issues are associated with using multiple MAC-CE commands to activate / deactivate UE reception of SP DL PRS.

[0111] According to one implementation, a single MAC-CE block may be defined for activating or deactivating the transmission of multiple UL PRS (e.g., SRS for positioning) or the reception of multiple DL PRS, or a combination of the transmission of multiple UL PRS and the reception of multiple DL PRS in a UE. For example, a single MAC-CE block may be used to activate or deactivate the transmission of multiple SRS resource sets for positioning. In another example, a single MAC-CE block may be used to activate or deactivate the reception of multiple DL PRS resource sets for frequency layers. In another example, a single MAC-CE block may be used to jointly activate or deactivate the transmission of multiple SRS resource sets for positioning and multiple DL PRS resource sets and reception for frequency layers, which may be used, for example, for multi-cell RTT positioning. By using a single MAC-CE to activate or deactivate multiple DL and / or UL PRS resource sets, fewer bits will be required, and therefore less overhead and latency will be required, compared to the case where one MAC-CE block is used for each separate DL or UL PRS resource set.

[0112] Figure 6 An implementation of a MAC-CE block 600 that may be used to activate or deactivate multiple DL or UL PRS resource sets is shown by way of example. Figure 6 As shown, the MAC-CE block 600 includes multiple PRS resource set identifiers (IDs) 602 with a single BWP ID 604 and a single component carrier (CC) ID 606. The BWP ID 604 provides an identifier of the BWP, and the CCID provides an identifier of the component carrier associated with the multiple PRS resource sets indicated by the multiple PRS resource set IDs 602. It should be understood that the MAC-CE block 600 may include additional fields, such as Figure 5 As shown in or Figure 7-10 6. The multiple PRS resource set ID 602 ​​may be for a DL PRS or a UL PRS, such as an SRS for positioning. In the MAC-CE block 600, the multiple PRS resource set IDs 602 are shown as multiple separate fields, but may be a single field including a list with multiple PRS resource set IDs. For the MAC-CE block 600, all PRS resource sets identified by the PRS resource set ID 602 ​​correspond to a single BWP identified by the BWP ID 604 and to a single CC identified by the CC ID 606. Therefore, using the MAC-CE block 600, there is no need to configure the BWP and CC separately for each activated or deactivated DL or UL PRS.

[0113] Figure 7 1 shows an implementation of a MAC-CE block 700 that may be used to activate or deactivate multiple DL or UL PRS resource sets. Figure 7 As shown, the MAC-CE block 700 includes multiple PRS resource set IDs 702 with a single A / D field 704 that indicates whether all indicated PRS resource sets are activated or deactivated, for example, where 1 indicates activation and 0 indicates deactivation. It should be understood that the MAC-CE block 700 may include, for example, Figure 5 shown in or Figure 6 and 8 10. The multiple PRS resource set IDs 702 may be for DL ​​PRS or UL PRS, such as SRS for positioning. In the MAC-CE block 700, the multiple PRS resource set IDs 702 are shown as multiple separate fields, but may be a single field including a list with multiple PRS resource set IDs. For the MAC-CE block 700, the same A / D field 704 is used to activate or deactivate all PRS resource sets identified by the PRS resource set ID 702.

[0114] Figure 8 FIG. 8 shows an implementation of a MAC-CE block 800 that may be used to activate multiple DL or UL PRS resource sets. Figure 8 As shown, the MAC-CE block 800 includes multiple PRS resource set IDs 802 with a single spatial relationship information type 804, and the spatial relationship information type 804 indicates the type or condition of the spatial relationship reference signal. The type or condition of the spatial relationship reference signal, for example, identifies the type of reference signal used to indicate the uplink transmission beam that the UE can use to precode the UL PRS resource set. For DL ​​PRS, the spatial relationship information is sometimes referred to as the QCL source or transmission configuration indicator (TCI) state. The type or condition of the spatial relationship reference signal can be, for example, UL PRS, DL PRS, SSB, or CSIRS. It should be understood that the MAC-CE block 800 may include, for example, Figure 5 shown in or Figure 6 , 7 , 9 and 10. The multiple PRS resource set IDs 802 may be for DL ​​PRS or UL PRS, for example, SRS for positioning. In the MAC-CE block 800, the multiple PRS resource set IDs 802 are shown as multiple separate fields, but may be a single field including a list with multiple PRS resource set IDs. For the MAC-CE block 800, all PRS resource sets identified by the PRS resource set IDs 802 have the same type of spatially related reference signals.

[0115] Fig. 9 9 shows an implementation of a MAC-CE block 900 and an RRC 910 that may be used to activate or deactivate multiple DL and / or UL PRS resource sets. Fig. 9 As shown, the RRC 910 includes a plurality of PRS resource set IDs 912 that may be activated or deactivated by the MAC-CE block 900. In the RRC 910, the plurality of PRS resource set IDs 912 are shown as a plurality of separate fields, but may be a single field including a list having a plurality of PRS resource set IDs. In one implementation, the RRC 910 may include a list of sets of PRS resource sets, such as row 1: {set 0, set 1}, row 2: {set 2, set 3}, etc. The MAC-CE 900 includes an identifier field 902 that indicates one or more PRS resource sets in the set of PRS resource sets to be activated or deactivated from the RRC 910. It should be appreciated that the MAC-CE block 900 may include an identifier field 902 such as in Figure 5 shown in or Figure 6-810. The multiple PRS resource set IDs 912 in the RRC 910 may be for DL ​​PRS or UL PRS, for example, SRS for positioning. Using the MAC-CE block 900 and the RRC 910, multiple PRS resource sets may be indicated for activation or deactivation without dedicating 4 bits for each PRS resource set in the MAC-CE block 900.

[0116] Fig.10 1 shows an implementation of a MAC-CE block 1000 that can be used to activate multiple DL or UL PRS resource sets. Fig.10 As shown, MAC-CE block 1000 includes multiple PRS resource set IDs 1002 with a single spatial relation information ID 1004, and the spatial relation information ID 1004 indicates the identity of the spatial relation reference signal. The identity of the spatial relation reference signal, for example, identifies a reference signal used to indicate an uplink transmission beam that the UE can use to precode the UL PRS resource set. For DL ​​PRS, the spatial relation information is sometimes referred to as QCL source or transmission configuration indicator (TCI) status. It should be understood that MAC-CE block 1000 may include, for example, Figure 5 shown in or Figure 6-9 1002. The multiple PRS resource set IDs 1002 may be for a DL PRS or a UL PRS, for example, an SRS for positioning. In the MAC-CE block 1000, the multiple PRS resource set IDs 1002 are shown as multiple separate fields, but may be a single field including a list with multiple PRS resource set IDs. For the MAC-CE block 1000, all PRS resource sets identified by the PRS resource set IDs 1002 have the same spatial relationship reference signal.

[0117] Fig.11 1 shows an implementation of a MAC-CE block 1100 and an RRC 1110 that can be used to jointly activate or deactivate multiple DL and UL PRS resource sets. Fig.11As shown, the RRC 1110 includes multiple different sets of joint UL PRS and DL PRS 1112, for example, listed as a tuple of a DL-PRS resource or resource set ID and a UL PRS (e.g., SRS for positioning) resource set ID. In the MAC-CE block 1100, the joint UL-PRS resource set ID and the DL PRS resource set ID are shown as multiple separate fields, but can be a single field including a list with a joint UL PRS resource set ID and a DL PRS resource set ID. Different sets of multiple UL PRS and multiple DL PRS listed in the RRC 1110 can be activated or deactivated by the MAC-CE block 1100. The MAC-CE block 1100 may include an identifier field 1102 that indicates one or more of the different sets of multiple UL PRS and multiple DL PRS to be activated or deactivated from the RRC 1110. It should be understood that the MAC-CE block 1100 may include an identifier field 1102 such as in Figure 5 shown in or Figure 6-8 10. Using the MAC-CE block 1100 and RRC 1110, multiple UL and DL PRS resource sets may be indicated for activation or deactivation without dedicating 4 bits for each individual UL and DL PRS resource set in the MAC-CE block 1100.

[0118] Fig.12 1 shows an implementation of a MAC-CE block 1200 that can be used to jointly activate multiple DL and UL PRS resource sets. Fig.12 As shown, the MAC-CE block 1200 includes multiple different sets of joint UL PRS IDs and DL PRS IDs 1202 with a single QCL field 1204, which indicates the QCL source for the indicated joint UL PRS and DL PRS to be activated. For DL ​​PRS, the QCL source is sometimes referred to as spatial relationship information. In the MAC-CE block 1200, the joint UL PRS resource set ID and DL PRS ID 1202 are shown as multiple separate fields, but can be a single field including a list with a joint UL PRS resource set ID and a DL PRS resource set ID. The identity of the QCL source, for example, identifies a reference signal beam used to indicate an uplink transmission beam that the UE can use for precoding SRS. It should be understood that the MAC-CE block 1200 may include, for example, in Figure 5 shown in or Figure 6-9For the MAC-CE block 1200, all PRS resource sets identified by the UL and DL PRS resource set ID 1202 have the same QCL field, and there is no need to configure the QCL field separately for each UL and each DL PRS resource set. In addition, in one implementation, when the QCL source identified in the QCL field 1204 for the activated DL-PRS resource set and SRS resource set is another DL-PRS resource, there is no need to add the TRP-ID (e.g., PRS resource set ID) field because it will be the same as the TRP-ID of the activated DL PRS resource set. For example, the TRP ID of the DL PRS used as the QCL source must be from the same TRP as the TRP ID of the activated DL PRS.

[0119] Although Figure 6-12 Various fields that may be used with a single MAC-CE block that may be used to activate or deactivate multiple DL and / or UL PRS resource sets are shown separately, but any combination of fields may be included in a MAC-CE block and additional fields may also be used, such as in Figure 5 The fields exposed in .

[0120] Fig.13 The implementation of the MAC-CE block 1300 is shown by way of example. The MAC-CE block 1300 includes Figure 6-12 All fields discussed in Activate or Deactivate multiple DL and / or UL PRS resource sets. For example, Fig.13An RRC 1310 is shown including multiple PRS resource set IDs 1312 that can be activated or deactivated by the MAC-CE block 1300 and multiple sets 1314 of tuples of UL PRS and DL PRS that can be jointly activated or deactivated by the MAC-CE block 1300. The multiple PRS resource set IDs 1312 can be for DL ​​PRS or UL PRS, for example, SRS for positioning. In the RRC 1310, the multiple PRS resource set IDs 1312 and the joint UL PRS resource set ID and DL PRS resource set ID are shown as multiple separate fields, but can be a single field or two fields, which include a list with multiple PRS resource set IDs and the joint UL PRS resource set ID and DL PRS resource set ID. In some implementations, the PRS resource set ID 1312 and the set 1314 of tuples of UL PRS and DL PRS can be provided by a separate RRC. The MAC-CE block 1300 may include an identifier field 1302 indicating one or more of a PRS resource set ID 1312 or a set 1314 of tuples of UL PRS and DL PRS from the RRC 1310. The MAC-CE block 1300 may also include a BWP ID 1303 and a CC ID 1304 to identify a single BWP and CC corresponding to a plurality of UL and / or DL ​​PRSs that are activated or deactivated. The MAC-CE block 1300 may also include an A / D field 1305 to indicate whether the indicated plurality of UL and / or DL ​​PRSs are activated or deactivated. The MAC-CE block 1300 may also include a spatial relationship information type 1306, a spatial relationship information identifier 1307, and a QCL source 1308 corresponding to the indicated plurality of UL and / or DL ​​PRSs.

[0121] Fig.14 Is in Figure 1 1400 of various messages sent between components of the communication system 100 are shown, illustrating the use of a single MAC-CE to activate or deactivate multiple DL and / or UL PRS resource sets. The location server 1402 may be, for example, Figure 1 The location server 172 shown, Figure 2A Location server 230a, 230b or Figure 2BLMF 270 of the present invention. UE 104 may be configured to perform UE-assisted positioning or UE-based positioning, in which the UE itself determines its position using, for example, assistance data provided to it, and may be configured to perform multi-cell RTT positioning. In message flow 1400, although it is assumed that UE 104 and location server 1402 communicate using the aforementioned LPP positioning protocol, it is also possible to use NPP or a combination of LPP and NPP or other future protocols (such as NRPPa). It should be understood that the UE 104 may perform multiple cell RTT positioning. Fig.14 Initial or additional conventional phases not shown in FIG, such as capability request and response, requesting and providing assistance data, etc.

[0122] At stage 1, the serving base station 102 provides a configuration of at least one of a plurality of DL PRSs, a plurality of UL PRSs (e.g., SRSs for positioning), or a combination thereof to the UE 104. For example, the serving base station 102 may receive the configuration from the location server 1402 and provide the configuration to the UE 104. For example, the configuration of the plurality of DL and / or UL PRSs may be defined according to the BWP, and may define a list of PRS resources and a list of PRS resource sets, wherein the resource set defines a PRS resource set.

[0123] At stage 2, as indicated by the dashed line, the UE 104 may optionally receive a message (such as an RRC message) from the serving base station 102, the message including multiple different UL PRS or DL ​​PRS sets that may be activated or deactivated by a single MAC-CE block and / or multiple different UL PRS or DL ​​PRS sets that may be jointly activated or deactivated by a single MAC-CE block. For example, the RRC message may include multiple different PRS resource ID sets of DL PRS to be received, UL PRS to be sent. For example, the PRS resource ID set may include a tuple of DL PRS resource IDs and UL PRS resource IDs of DL PRS and UL PRS to be jointly activated or deactivated.

[0124] At stage 3, the UE 104 receives from the serving base station 102 a single MAC-CE block that activates or deactivates at least one of: transmission of multiple UL PRSs; reception of multiple DL PRSs, or a combination thereof. For example, the MAC-CE block may activate or deactivate transmission of multiple UL PRSs (e.g., SRSs for positioning) by identifying multiple UL PRS resource sets, each of which includes at least one UL PRS resource. The MAC-CE block may activate or deactivate reception of multiple DL PRSs, for example, by identifying multiple DL PRS resources, multiple DL PRS resource sets, or multiple DL PRS frequency layers. The MAC-CE block may jointly activate or deactivate transmission of UL PRSs and reception of DL PRSs, for example, by identifying multiple UL PRS resource sets and associated multiple DL PRS resources, multiple DL PRS resource sets, or multiple DL PRS frequency layers. The MAC-CE block may identify multiple UL and / or DL ​​PRS using an identifier field that refers to one or more of multiple different UL PRS and / or DL ​​PRS sets in the RRC message received at stage 2. In addition to identifying multiple UL and / or DL ​​PRS, the MAC-CE block may also identify a single BWP ID and CCID for all multiple UL and / or DL ​​PRS. The MAC-CE block may include a single activation / deactivation (A / D) bit for all multiple UL and / or DL ​​PRS. The MAC-CE block may include a single type or a single case of spatial relationship for all multiple UL and / or DL ​​PRS, for example, ULPRS, DL PRS, SSB, or CSIRS. The MAC-CE block may include a spatial relationship information identifier, for example, which indicates the identity of the spatial relationship reference signal of all multiple UL and / or DL ​​PRS. The MAC-CE block may include a QCL field that identifies the QCL source of multiple UL and DL PRS to be jointly activated.

[0125] At stage 4, UE 104 may activate or deactivate reception of multiple DL PRSs transmitted by serving base station 102 in response to the single MAC-CE block received at stage 3. For example, UE 104 may activate or deactivate multiple DL PRS resources, multiple DL PRS resource sets, or multiple DL PRS frequency layers as identified by the MAC-CE block received at stage 3. For example, stage 4 may be performed if the MAC-CE identifies a DL PRS to be activated or deactivated without or in conjunction with a UL PRS.

[0126] At stage 5, UE 104 may activate or deactivate reception of multiple DL PRSs transmitted by neighboring base stations 102-1 and 102-2 in response to the single MAC-CE block received at stage 3. For example, UE 104 may activate or deactivate multiple DL PRS resources, multiple DL PRS resource sets, or multiple DL PRS frequency layers as identified by the MAC-CE block received at stage 3. For example, stage 5 may be performed if the MAC-CE identifies a DL PRS to be activated or deactivated without or in conjunction with a UL PRS.

[0127] At stage 6, UE 104 may activate or deactivate transmission of multiple UL PRS (e.g., SRS for positioning) to serving base station 102 and neighboring base stations 102-1 and 102-2 in response to the single MAC-CE block received at stage 3. For example, UE 104 may activate or deactivate multiple UL PRS resource sets as identified by the MAC-CE block received at stage 3. For example, stage 6 may be performed if the MAC-CE identifies a UL PRS to be activated or deactivated without or in conjunction with a DL PRS.

[0128] At stage 7, the UE 104 may perform positioning measurements using the received DL PRS and / or the transmitted UL PRS from stages 4, 5, and 6 after being activated or deactivated by the MAC-CE block from stage 3. The UE 104 may perform positioning methods such as time of arrival (TOA), reference signal time difference (RSTD), time difference of arrival (TDOA), reference signal received power (RSRP), time difference between reception and transmission of a signal (Rx-Tx), etc. In some implementations, multiple DL PRSs and UL PRSs may be jointly activated or deactivated by the MAC-CE block from stage 3, and the positioning measurements performed by the joint DL PRSs and UL PRSs may be, for example, multi-cell RTT positioning measurements. In a UE-based positioning method, the UE may further determine the position estimate using a location measurement (e.g., using the location of a base station) that may be provided in an assistance data message (not shown).

[0129] At stage 8, UE 104 may send a location measurement report, e.g., using an LPP message, to location server 1402. The location measurement report may provide the location measurement from stage 7 and / or a location estimate (if determined).

[0130] At stage 9 , the location server 1402 may determine the UE location based on any positioning measurements received at stage 8 , or may verify the UE location received at stage 8 .

[0131] Fig.15 A flow chart of an exemplary method 1500 for location of a user equipment (UE), such as UE 104, performed by the UE in a manner consistent with the disclosed implementations is shown.

[0132] At block 1502, the UE receives a configuration of at least one of a plurality of downlink (DL) positioning reference signals (PRS), a plurality of uplink (UL) PRS, or a combination thereof from a network entity (such as a location server), such as, for example, in Fig.14 At block 1504, a single medium access control-control element (MAC-CE) block is received from a serving base station to activate or deactivate at least one of: transmission of multiple UL PRSs; reception of multiple DL PRSs, or a combination thereof, e.g., as in Fig.14 At block 1506, in response to a single MAC-CE block, at least one of: transmission of multiple UL PRSs, reception of multiple DL PRSs, or a combination thereof is activated or deactivated, e.g., as in Fig.14 discussed in stages 4, 5 and 6 of the .

For example, the at least one UL PRS resource may be at least one sounding reference signal resource (SRS) used for positioning.

[0142] In one implementation, a single MAC-CE block includes a single quasi-co-located source applied to multiple UL PRSs and multiple DL PRSs, for example, as in Fig.12 and 13 as well as Fig.14 In one example, the reference signal applied to multiple UL PRS and multiple DL PRS as a single quasi-co-located (QCL) source is another DL PRS resource, and wherein the transmit reception point (TRP) identifier of the multiple DL PRS is also the TRP identifier of the DL PRS resource used as the QCL source, for example, as in Fig.12 discussed at.

[0143] Fig.16 A flow chart is shown of an exemplary method 1600 for position determination of a user equipment (UE), such as UE 104, performed by a serving base station of the UE in a manner consistent with the disclosed implementations.

[0144] At block 1602, a serving base station provides a configuration of at least one of a plurality of downlink (DL) positioning reference signals (PRS), a plurality of uplink (UL) PRS, or a combination thereof to a UE, such as in Fig.14At block 1604, a single medium access control-control element (MAC-CE) block is sent to the UE to activate or deactivate at least one of the following in the UE: transmission of multiple UL PRSs; reception of multiple DL PRSs, or a combination thereof, e.g., as in Fig.14 At block 1606, in response to a single MAC-CE block, the serving base station receives or stops receiving transmissions of a plurality of ULPRSs from the UE, sends or stops sending a plurality of DL PRSs to the UE, or a combination thereof, e.g., as in Fig.14 discussed in stages 4, 5 and 6 of the .

[0145] In one implementation, the serving base station provides the UE with a configuration of at least one of a plurality of DLPRSs, a plurality of UL PRSs, or a combination thereof by providing the configuration from a location server to the UE, for example, as in Fig.14 This was discussed in Phase 1 of .

[0146] In one implementation, a single MAC-CE block activates or deactivates transmission of multiple UL PRS resource sets in the UE, wherein each UL PRS resource set includes at least one PRS resource, and in response, the serving base station receives or stops receiving transmission of the multiple UL PRSs, for example, as in Fig.14 As discussed in stages 3 and 6 of . For example, at least one UL PRS resource includes at least one sounding reference signal resource (SRS) for positioning.
