Description

Technical Field

[0001] In general, the subject matter of this case relates to wireless communication, and specifically to the technology and apparatus for transmitting the physical downlink control channel for multicast / broadcast system services. Prior Technology

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems utilize multiplexing access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmission power). Examples of such multiplexing access technologies include Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), Time Division Synchronous Code Division Multiple Access (TD-SCDMA), and Long Term Evolution (LTE). LTE / Enhanced LTE is a collection of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile service standard released by the 3rd Generation Partnership Project (3GPP).

[0003] A wireless network may include one or more network nodes that support communication between user equipment (UE) or multiple UEs. UEs may communicate with network nodes via downlink and uplink communication. "Downlink" (or "DL") refers to the communication link from the network node to the UE, while "uplink" (or "UL") refers to the communication link from the UE to the network node.

[0004] The aforementioned multiplexing access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR) (which may be referred to as 5G) is a collection of enhancements to the LTE mobile service standard released by 3GPP. NR is designed to better support mobile broadband internet access by: improving spectrum efficiency, reducing costs, improving service, using new spectrum and better integrating with other open standards using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink, using CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0040] Several forms of telecommunications systems will now be presented with reference to various devices and technologies. These devices and technologies will be described in detail below and illustrated in the accompanying drawings by way of various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such an element is implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0041] Although this document may use terms commonly associated with 5G or New Radio (NR) Radio Access Technology (RAT) to describe the various forms, the various forms of the content herein may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0042] Figure 1 is a schematic diagram illustrating an example of a wireless network 100 according to the contents of this case. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, as well as other examples. The wireless network 100 may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. Base station 110 is the entity communicating with UE 120. Base station 110 (sometimes referred to as BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a transport receiver point (TRP). Each base station 110 can provide communication coverage for a specific geographic area. In the 3GPP, depending on the context in which the term "cell" is used, the term "cell" can represent the coverage area of ​​base station 110 and / or the base station subsystem serving that coverage area.

[0043] Base station 110 can provide communication coverage for macrocells, picocells, femtocells, and / or other types of cells. Macrocells can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. Picocells can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. Femtocells can cover a relatively small geographic area (e.g., a home) and can allow restricted access by UE 120 associated with that femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Base station 110 for macrocells can be referred to as a macro base station. Base station 110 for picocells can be referred to as a pico base station. Base station 110 for femtocells can be referred to as a femto base station or a home base station. In the example shown in Figure 1, BS 110a can be a macro base station for macro cells 102a; BS 110b can be a pico base station for pico cells 102b; and BS 110c can be a femto base station for femto cells 102c. The base station can support one or more (e.g., three) cells.

[0044] In some instances, the cell may not necessarily be stationary, and the geographical area of ​​the cell may move depending on the location of the base station 110 (e.g., the mobile base station). In some instances, base stations 110 may be interconnected to each other and / or one or more other base stations 110 or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0045] Wireless network 100 may include one or more relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., base station 110 or UE 120) and send data transmissions to a downstream station (e.g., UE 120 or base station 110). A relay station may be a UE 120 that can relay transmissions for other UE 120s. In the example shown in Figure 1, BS 110d (e.g., a relay base station) can communicate with BS 110a (e.g., a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. Base station 110 used for relay communication may be referred to as a relay station, relay base station, relay, etc.

[0046] In some embodiments, the term "base station" or "network entity" may represent a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more of these elements. For example, in some embodiments, "base station" or "network entity" may represent a CU, DU, RU, near real-time (near RT) RAN intelligent controller (RIC), or non-real-time (non-RT) RIC, or a combination thereof. In some embodiments, the term "base station" or "network entity" may represent a device configured to perform one or more functions, such as those described herein in conjunction with network entity 110. In some embodiments, the term "base station" or "network entity" may represent a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a plurality of different devices (which may be located in the same geographical location or in different geographical locations) may be configured to perform at least a portion of a function, or to replicate at least a portion of the performance of that function, and the term "base station" or "network entity" may represent any one or more of those different devices. In some formats, the term "base station" or "network entity" may represent one or more virtual base stations or one or more virtual base station functions. For example, in some formats, two or more base station functions may be exemplified on a single device. In some formats, the term "base station" or "network entity" may represent one base station function instead of another. In this way, a single device may include more than one base station.

[0047] Wireless network 100 can be a heterogeneous network, comprising different types of base stations 110, such as macro base stations, pico base stations, femto base stations, repeater base stations, etc. These different types of base stations 110 can have different transmission power levels, different coverage areas, and / or different effects on interference in wireless network 100. For example, macro base stations can have high transmission power levels (e.g., 5 to 40 watts), while pico base stations, femto base stations, and repeater base stations can have lower transmission power levels (e.g., 0.1 to 2 watts).

[0048] Network controller 130 can be coupled to or communicate with a group of base stations 110, and provide coordination and control for such base stations 110. Network controller 130 can communicate with base stations 110 via a backhaul communication link. Base stations 110 can communicate with each other directly or indirectly via wireless or wired backhaul communication links.

[0049] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or user units. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop, a cordless phone, a wireless loop (WLL) station, a tablet computer, a camera, a gaming device, a laptop, a smart computer, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio unit), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, and / or any other suitable device configured to communicate via wireless media.

[0050] Some UEs 120 can be considered Machine Type Communication (MTC) or Evolved or Enhanced Machine Type Communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags capable of communicating with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 can be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 can be considered customer premises equipment. UEs 120 may be included within a housing that houses the components of the UE 120, such as processor components and / or memory components. In some instances, processor components and memory components may be coupled together. For example, processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0051] Typically, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT can be referred to as a radio technology, air interface, etc. A frequency can be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0052] In some instances, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such instances, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0053] Devices in the Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., by frequency or wavelength. For example, devices in the Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been identified as the frequency range designations FR1 (410 MHz – 7.125 GHz) and FR2 (24.25 GHz – 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "below 6 GHz" band in various documents and articles. A similar naming issue sometimes arises for FR2; in documents and articles, FR2 is often (interchangeably) referred to as the "millimeter wave" band, although this is different from the Extremely High Frequency (EHF) band (30 GHz – 300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU).

[0054] The frequencies between FR1 and FR2 are often referred to as intermediate frequency (IF) frequencies. Recent 5G NR studies have identified the operating bands for these IF frequencies as the frequency range designation FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 into the IF frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating frequency bands have been identified as the frequency range designations FR4a or FR4-1 (52.6 GHz – 71 GHz), FR4 (52.6 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0055] Considering the above examples, unless otherwise explicitly stated, it should be understood that, as used herein, the term "below 6 GHz" can broadly refer to frequencies that are less than 6 GHz, within FR1, or may include intermediate frequency bands. Furthermore, unless otherwise explicitly stated, it should be understood that, as used herein, the term "millimeter wave" can broadly refer to frequencies that may include intermediate frequency bands, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. It is contemplated that frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to such modified frequency ranges.

[0062] As noted above, Figure 1 is provided as an example. Other examples may differ from those described with respect to Figure 1.

[0063] Figure 2 is a schematic diagram illustrating an example 200 of communication between base station 110 and UE 120 in wireless network 100, according to the contents of this case. Base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).

[0064] At base station 110, transmission processor 220 can receive data intended for UE 120 (or a group of UEs 120) from data source 212. Transmission processor 220 can select one or more modulation and decoding schemes (MCS) for UE 120 based at least in part on one or more Channel Quality Indicators (CQIs) received from UE 120. Base station 110 can process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120, and can provide data symbols for UE 120. Transmission processor 220 can process system information (e.g., semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, permission and / or upper-layer signaling), and provide management burden symbols and control symbols. The transmission processor 220 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulated reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmission (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding, if applicable) on data symbols, control symbols, administrative burden symbols, and / or reference symbols, and can provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of data machines 232 (e.g., T data machines), shown as data machines 232a to 232t. For example, each output symbol stream can be provided to a modulator element (shown as MOD) of the data machine 232. Each data machine 232 can use a corresponding modulator element to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may also use a corresponding modulator element to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sampled stream to obtain a downlink signal. Modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via corresponding groups of antennas 234 (e.g., T antennas), shown as antennas 234a to 234t.

[0065] At UE 120, a set of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from base station 110 and / or other base stations 110, and can provide a set of received signals (e.g., R received signals) to a set of data terminals 254 (e.g., R data terminals), shown as data terminals 254a to 254r. For example, each received signal can be provided to a demodulator element (shown as DEMOD) of data terminal 254. Each data terminal 254 can use a corresponding demodulator element to modulate (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain an input sample. Each data terminal 254 can use the demodulator element to further process the input sample (e.g., for OFDM) to obtain received symbols. MIMO detector 256 can obtain the received symbols from data terminal 254, can perform MIMO detection on the received symbols (if applicable), and can provide the detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to the data slot 260, and provide decoded control information and system information to the controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, among other instances. In some instances, one or more components of the UE 120 may be included in the housing 284.

[0066] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0067] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or may be included in one or more antenna panels, one or more antenna groups, one or more groups of antenna elements and / or one or more antenna arrays, and other examples. Antenna panels, antenna groups, groups of antenna elements and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), a group of coplanar antenna elements, a group of non-coplanar antenna elements, and / or one or more antenna elements coupled to one or more transmitting and / or receiving elements, such as one or more elements of FIG2.

[0068] On the uplink, at UE 120, transmission processor 264 can receive and process data from data source 262 and control information (e.g., reports including RSRP, RSSI, RSRQ, and / or CQI) from controller / processor 280. Transmission processor 264 can generate reference symbols for one or more reference signals. Symbols from transmission processor 264 can be pre-encoded (if applicable) by TX MIMO processor 266, further processed by data unit 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some instances, data unit 254 of UE 120 may include modulators and demodulators. In some instances, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, data unit 254, MIMO detector 256, receiver processor 258, transmission processor 264, and / or TX MIMO processor 266. The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to perform various forms of any of the methods described herein (e.g., refer to Figures 4-12).

[0069] At base station 110, uplink signals from UE 120 and / or other UEs can be received by antenna 234, processed by modem 232 (e.g., demodulator element of modem 232, shown as DEMOD), detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data slot 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and can communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 for scheduling one or more UEs 120 for downlink and / or uplink communication. In some instances, modem 232 of base station 110 may include modulator and demodulator. In some instances, base station 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receiver processor 238, transmitter processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform any of the methods described herein in various ways (e.g., refer to Figures 4-12).

[0070] As described in more detail elsewhere herein, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or any other element of FIG. 2 may perform one or more technologies associated with PDCCH transmission for MBS services. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or any other element of FIG. 2 may perform or direct operations such as process 500 of FIG. 5, process 600 of FIG. 6, process 700 of FIG. 7, process 800 of FIG. 8, process 900 of FIG. 9, process 1000 of FIG. 10, and / or other processes as described herein.

In some instances, memory 242 and / or memory 282 may include non-transitory computer-readable media storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when one or more instructions are executed by one or more processors of base station 110 and / or UE 120 (e.g., directly or after compilation, translation, and / or interpretation), they may cause one or more processors, UE 120, and / or base station 110 to perform or direct operations such as process 500 of FIG. 5, process 600 of FIG. 6, process 700 of FIG. 7, process 800 of FIG. 8, process 900 of FIG. 9, process 1000 of FIG. 10, and / or other processes as described herein. In some instances, execution instructions may include execution instructions, translation instructions, compilation instructions, and / or interpretation instructions, among others.

[0071] In some configurations, the UE includes: a component for monitoring the search space associated with the PDCCH corresponding to the MBS PDCCH for at least one MBS PDCCH communication having a PDCCH payload scrambled according to a PDCCH payload scrambling sequence based on an RNTI value, wherein the RNTI value is equal to G-RNTI or 0; and / or a component for receiving at least one MBS PDCCH communication. The components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0072] In some configurations, the UE includes components for monitoring the search space associated with the PDCCH corresponding to the MBS PDSCH for at least one MBS PDCCH communication having a CCE index corresponding to a hash function based on the RNTI value, wherein the RNTI value is equal to G-RNTI or 0; and / or components for receiving at least one MBS PDCCH communication. Components for the UE to perform the operations described herein may include, for example, one or more of the following: communication manager 140, antenna 252, modem 254, MIMO detector 256, receiver processor 258, transmitter processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0073] In some configurations, the UE includes components for receiving MBS configurations for a plurality of G-RNTIs of a cell; and / or for monitoring at least one search space associated with a PDCCH corresponding to the MBS PDSCH of the cell based on the MBS configuration for at least one MBS PDSCH communication scheduled among a plurality of MBS PDSCH communications. Components for the UE to perform the operations described herein may include one or more of, for example, a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0074] In some configurations, the network node includes components for transmitting an MBS configuration indicating a PDCCH payload scrambling sequence based on the value of the RNTI for the search space associated with the PDCCH corresponding to the MBS PDSCH, wherein the RNTI value is equal to G-RNTI or 0; and / or components for transmitting at least one MBS PDCCH communication based at least partially on the configuration. Components for the network node to perform the operations described herein may include, for example, one or more of the following: a communication manager 150, a transmission processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receiver processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0075] In some configurations, the network node includes components for transmitting MBS configuration indicating a PDCCH hash function based on the value of the RNTI for the search space associated with the PDCCH corresponding to the MBS PDSCH, wherein the value of the RNTI is equal to G-RNTI or 0; and / or components for transmitting at least one MBS PDCCH communication based at least in part on the configuration. Components for the network node to perform the operations described herein may include, for example, one or more of the following: a communication manager 150, a transmission processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receiver processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0076] In some configurations, the network node includes components for transmitting MBS configurations for a plurality of G-RNTIs of the cell; and / or components for transmitting at least one MBS PDCCH communication of at least one MBS PDSCH communication among a plurality of MBS PDSCH communications based on the MBS configuration and using at least one search space associated with a PDCCH corresponding to the MBS PDSCH of the cell. Components for the network node to perform the operations described herein may include, for example, one or more of the following: a communication manager 150, a transmission processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receiver processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0077] Although the blocks in Figure 2 are shown as different components, the functions described above in conjunction with the blocks can be implemented in a single hardware, software, or combined component or various combinations of components. For example, the functions described with respect to the transmission processor 264, the reception processor 258, and / or the TX MIMO processor 266 can be executed by or under the control of the controller / processor 280.

[0078] As noted above, Figure 2 is provided as an example. Other examples may differ from those described with respect to Figure 2.

[0079] The deployment of communication systems (such as 5G NR systems) can involve various elements or components arranged in multiple ways. In a 5G NR system or network, network nodes, network entities, network mobile elements, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in aggregated or decomposed architectures. For example, a base station (such as a Node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an Access Point (AP), a TRP, or a cell, and other instances) or one or more units (or elements) performing base station functions can be implemented as an aggregated base station (also known as a standalone base station or monolithic base station) or a decomposed base station.

[0080] Aggregated base stations can be configured to utilize radio protocol stacks that are physically or logically integrated within a single RAN node (e.g., in a single device or cell). Decomposed base stations can be configured to utilize protocol stacks that are physically or logically distributed among two or more cells (such as CUs, one or more DUs, or one or more RUs). In some instances, the CU can be implemented within a RAN node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually distributed throughout one or more other RAN nodes. DUs can be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can also be implemented as a virtual cell, such as a Virtual Central Cell (VCU), a Virtual Distributed Cell (VDU), or a Virtual Radio Unit (VRU), among other instances.

[0081] The operation or network design of base station types can consider the aggregation characteristics of base station functions. For example, decomposed base stations can be used in IAB networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)) to facilitate scaling of the communication system by separating base station functions into one or more units that can be deployed independently. Decomposed base stations can include functions implemented across two or more units at various physical locations, as well as functions virtually implemented for at least one unit, which allows for flexibility in network design. Each unit of a decomposed base station can be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0082] Figure 3 is a schematic diagram illustrating an exemplary disaggregated base station architecture 300 according to the contents of this case. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more disaggregated control units (such as near-RT RIC 325 via an E2 link, or non-RT RIC 315 associated with a Service Management and Orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DU 330s via appropriate midrange links (such as via an F1 interface). Each of the DU 330s may communicate with one or more RU 340s via appropriate fronthaul links. Each of the RU 340s may communicate with one or more UE 120s via appropriate radio frequency (RF) access links. In some implementations, a UE 120 may be served by multiple RU 340s simultaneously.

[0083] Each of the units, including CU 310, DU 330, RU 340, and near-RT RIC 325, non-RT RIC 315, and SMO frame 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively referred to as signals) via wired or wireless transmission media. Each unit, or an associated processor or controller providing instructions to one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more other units via transmission media. In some instances, each unit may include a wired interface and a wireless interface, the wired interface being configured to receive or transmit signals via wired transmission media destined for one or more other units, and the wireless interface may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive or transmit signals via wireless transmission media destined for one or more other units, or both.

[0084] In some implementations, the CU 310 can host one or more higher-level control functions. These control functions may include Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, or Service Data Adaptation Protocol (SDAP) functions, among others. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP) functions), control plane functions (e.g., Central Unit-Control Plane (CU-CP) functions), or combinations thereof. In some implementations, the CU 310 can be logically separated into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface (such as an E1 interface). The CU 310 can be implemented, if necessary, to communicate with the DU 330 for network control and signaling.

[0085] Each DU 330 may correspond to a logic unit that includes one or more base station functions to control the operation of one or more RU 340s. In some configurations, the DU 330 may rely at least in part on functional separation, such as functional separation defined by 3GPP, to host one or more of the Radio Link Control (RLC) layer, MAC layer, and one or more high-PHY layers. In some configurations, the one or more high-PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, as well as other instances. In some configurations, the DU 330 may also host one or more low-PHY layers, such as those implemented by one or more modules for Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, or Physical Random Access Channel (PRACH) extraction and filtering, as well as other instances. Each layer (which may also be referred to as a module) can be implemented using an interface configured to transmit signals to other layers (and modules) hosted by the DU 330 or to control functions hosted by the CU 310.

[0086] Each RU 340 can implement lower-layer functions. In some deployments, based on function separation (e.g., function separation defined by 3GPP), such as lower-layer function separation, the RU 340 controlled by the DU 330 can correspond to a logical node for host RF processing functions or low-PHY layer functions (such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, and other instances). In this architecture, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UE 120s. In some implementations, the real-time and non-real-time modes of control and user plane communications with the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration allows each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as vRAN architecture).

[0087] The SMO framework 305 can be configured to support RAN deployment and the provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated entity resources for RAN coverage requirements, which can be managed via an operation and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform (such as the Open Cloud (O-Cloud) platform 390) to perform network element lifecycle management (e.g., exemplified by virtualized network elements) via a cloud computing platform interface (such as the O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some implementations, the SMO framework 305 can communicate with 4G RAN hardware models, such as the Open eNB (O-eNB) 311, via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0088] The non-RT RIC 315 can be configured to include logical functions for non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows (including model training and updates), or applications / features in the near-RT RIC 325, guided by policy principles. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325 (e.g., via an A1 interface). The near-RT RIC 325 can be configured to include logical functions that enable near-real-time control and optimization of RAN elements and resources through data collection and actions via interfaces connecting one or more CUs 310s, one or more DUs 330s, or both, and the O-eNB to the near-RT RIC 325 (e.g., via an E2 interface).

[0089] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 can receive parameters or external rich information from an external server. This information can be used by the near-RT RIC 325 and can be received from non-network data sources or network functions at the SMO framework 305 or the non-RT RIC 315. In some instances, the non-RT RIC 315 or near-RT RIC 325 can be configured to adjust RAN behavior or performance. For example, the non-RT RIC 315 can monitor long-term trends and patterns in performance and use AI / ML models to perform corrective actions via the SMO framework 305 (such as reconfiguration via the O1 interface) or via the establishment of RAN management policies (such as A1 interface policies).

[0090] Network nodes can use PDCCH transmissions to schedule PDSCH transmissions for UEs. However, multiple UEs may be interacting with and / or connected to the cell. To facilitate directing PDCCH transmissions to a specific UE among multiple UEs in the cell, the network node can scramble the PDCCH payload according to a scrambling sequence recognizable by the UE before modulation. In this way, UEs not targeted by the transmission can avoid decoding the scheduled transmission, and the network node can schedule each UE independently, even if there are more than one UE, the scheduled transmission can still be detected.

[0091] In some cases, the UE can be configured to monitor PDCCH transmissions with payloads scrambled according to a scrambling sequence based on RNTI values, where the RNTI value is equal to the cell RNTI (C-RNTI) or zero. In some cases, for example, if communication is intended for a UE-specific search space (USS) and if specific parameters are configured, the RNTI value is equal to C-RNTI, otherwise equal to 0.

[0092] For example, the UE can be configured to monitor PDCCH transmissions, which have included transmissions via pre-modulation based on... Opposite block The scrambled bit block produced by the scrambling operation performed The payload, where the scrambling sequence c(i) can be specified in the wireless communication standard. It can be initialized using the scrambling sequence initialization function. The scrambling sequence generator is initialized, where, for a UE-specific search space, if configured, then... It equals the higher-level parameter pdcch-DMRS-ScramblingID, and otherwise And if the higher-level parameter pdcch-DMRS-ScramblingID is configured, then Provided by C-RNTI for PDCCH in UE-specific search space, and otherwise =0.

[0093] The PDCCH payload scrambling described above is useful for directing PDCCH transmissions to one of multiple UEs. However, in MBS systems, since C-RNTI is UE-specific, attempts by network nodes to use this scrambling scheme to direct PDCCH transmissions to multiple UEs (e.g., for multicast and / or broadcast) will not succeed. Therefore, the scrambling scheme may suppress MBS communication and thus have a negative impact on network performance.

[0094] In some cases, for a shared search space (CSS), multiple UEs can monitor PDCCH candidates on the same CCE set. For example, for a search space set s associated with a core resource set (CORESET) p, the value used in the carrier indicator field... The corresponding service cell's activity downlink bandwidth portion (BWP) time slot PDCCH candidates in the search space set The corresponding CCE index at aggregation level L can be obtained from Provided, where for any CSS, For any USS, For pmod3=0, For pmod3=1, For pmod3=2 and D=65537; i=0, ..., L-1; This refers to the number of CCEs in CORESET p, numbered from 0 to... And, if any, per resource block (RB) set; if the UE is configured with a carrier indication field via carrier scheduling configuration parameters (e.g., CrossCarrierSchedulingConfig) for monitoring the PDCCH on it, then It is the carrier indicator field value; otherwise, including for any CSS, in Is the UE configured for use with The number of PDCCH candidates monitored is the aggregation level L of the corresponding service cell search space set s; for any CSS, For USS, This refers to all configurations for the CCE aggregation level L of the search space set s. On each value The maximum value; and used for The RNTI value is C-RNTI.

[0095] In this way, a single downlink control information (DCI) transmission can be delivered to all UEs. Different UEs have different C-RNTI values ​​for their UE-specific search space, and PDCCH candidates for different UEs can be mapped to different CCE sets. However, shared DCI transmission over a UE-specific search space is typically impossible. Therefore, in an MBS system, because the C-RNTI is UE-specific, attempts by network nodes to use C-RNTI-based hash functions to direct PDCCH transmissions to multiple UEs (e.g., for multicast and / or broadcast) will fail. Consequently, hash functions may inhibit MBS communication and thus negatively impact network performance.

[0096] In some cases, Cyclic Redundancy Check (CRC) can be used to provide error detection for DCI transmissions. To facilitate CRC, the entire payload can be used to calculate CRC parity bits according to a procedure that can be specified by the radio standard. The CRC parity bits can be scrambled with the corresponding RNTI, allowing the UE to interpret the CRC parity bits to detect errors. The CRC scrambling can be based on any number of different RNTIs, including C-RNTI, Modulation-Decoding Scheme Cell RNTI (MCS-C-RNTI), Configuration Scheduling RNTI (CS-RNTI), System Information RNTI (SI-RNTI), Paging RNTI (P-RNTI), Random Access RNTI (RA-RNTI), and / or Slot Format Indicator RNTI (SFI-RNTI), and other instances. Although G-RNTI can be used to scramble CRC parity bits, a single G-RNTI may not be sufficient for multiple PDSCH transmissions across multiple MBS services. Therefore, CRC scrambling using a single RNTI may suppress MBS communication and thus have a negative impact on network performance.

[0097] In some cases, the search space associated with the PDCCH corresponding to the MBS PDSCH may include, for example, an MBS-specific type of CSS (e.g., which may be referred to as Type x CSS). The search space can be used for group-shared PDCCH transmissions for multicast in RRC connection states. The monitoring priority of the search space associated with the PDCCH corresponding to the MBS PDSCH can be determined based on the search space set indexes of the Type x CSS set and the USS set, regardless of the DCI format of the group-shared PDCCH configured in the Type x CSS. The group-shared PDCCH used in MBS can be configured to support at least two DCI formats. For example, DCI format 1_0 can be used as the baseline for a first DCI format, where the CRC is scrambled using G-RNTI. DCI formats 1_1 or 1_2 can be used as the baseline for a second DCI format, where the CRC is scrambled using G-RNTI. However, as mentioned above, the payload scrambling scheme, hash function, and / or CRC scrambling scheme based on the USS may not be suitable for MBS communications.

[0098] Some patterns can provide PDCCH payload scrambling for PDCCH transmissions in scheduled MBS PDSCH communications. Some patterns can provide hash functions for PDCCH transmissions in scheduled MBS PDSCH communications. Some patterns can provide CRC scrambling for PDCCH transmissions in scheduled MBS PDSCH communications. The scrambling and hashing techniques described herein can be based on RNTIs that can have values ​​equal to 0 or equal to G-RNTI (or multiple G-RNTIs). In this way, PDCCH payload scrambling, hash functions, and CRC scrambling can be adapted for PDCCH transmissions used in scheduled MBS PDSCH communications, enabling multiple UEs to receive multicast and / or broadcast transmissions. Therefore, some patterns can facilitate multicast and / or broadcast transmissions, thus having a positive impact on network performance.

[0099] Figure 4 is a schematic diagram illustrating an example 400 associated with PDCCH transmission for MBS services, according to the contents of this case. As shown in Figure 4, network node 402 and UE 404 can communicate with each other. Network node 402 can communicate with multiple UEs 404 in the MBS implementation, although only one such UE 404 is illustrated in Figure 4.

[0100] As indicated by component symbol 406, network node 402 can transmit and UE 404 can receive MBS configuration. In some cases, for example, a Common Frequency Resource (CFR) configuration can be provided to UE 404. The CFR may include information indicating the location in the frequency domain where MBS data can be scheduled. The CFR configuration may include other parameters for facilitating MBS communication. For example, RRC configuration for CORESET and associated search space may be provided as part of the CFR configuration.

[0101] In some configurations, the MBS configuration (and / or one or more of its configurations) may be, may include, may be included in, or may be similar to a CFR configuration. In some configurations, network node 402 may transmit, and UE 404 may receive, a configuration for the PDCCH DMRS scrambling identifier for the set of control resources associated with the search space. For example, this configuration may configure the pdcch-DMRS-ScramblingID parameter. In some configurations, network node 402 may transmit, and UE 404 may receive, a dedicated configuration indication that configures the search space associated with the PDCCH corresponding to the MBS PDSCH. The dedicated configuration indication may be transmitted using dedicated RRC messages and / or dedicated RRC parameters. In some configurations, network node 402 may transmit, and UE 404 may receive an MBS configuration that configures multiple G-RNTIs for the cell. In some configurations, at least one of the plurality of G-RNTIs may include the value of an RNTI associated with at least one of the following: a PDCCH payload scrambling sequence, a hash function corresponding to a CCE index, or a CRC scrambling sequence. In some configurations, a list of G-RNTIs may be used to configure G-RNTIs. In some configurations, this configuration may indicate a mapping between G-RNTIs and corresponding multicast services. The multicast service may include a specified multicast service identifier (ID). In some configurations, network node 402 may transmit, and UE 404 may receive, a configuration indicating a configurable specific value for the RNTI. The configurable specific value for the RNTI may be associated with at least one of the following: a PDCCH payload scrambling sequence, a hash function corresponding to a CCE index, or a CRC scrambling sequence. In some configurations, network node 402 may transmit, and UE 120 may receive, an RRC configuration indicating a mapping between at least one search space and at least one of the plurality of G-RNTIs. Any of the above configurations can be included in the CFR configuration and / or MBS configuration, as well as in other instances.

[0102] As shown by component symbol 408, network node 402 can use scrambling sequences, hash functions, and / or CRC sequences, as well as other instances, to generate MBS PDCCH communications, as described herein. As shown by component symbol 410, UE 404 can monitor the search space for at least one MBS PDCCH communication.

[0103] For example, in some configurations, UE 404 can monitor the search space associated with the PDCCH corresponding to the MBS PDSCH for at least one MBS PDCCH communication with a PDCCH payload scrambling sequence scrambled according to a value based on RNTI. The RNTI value can be equal to G-RNTI or 0. The RNTI value can be equal to 0, and UE 404 can receive the configuration for the PDCCH DMRS scrambling ID for the CORESET associated with the search space. In some configurations, UE 404 does not receive the configuration for the PDCCH DMRS scrambling ID for the CORESET associated with the search space. For example, the payload scrambling of the PDCCH used for scheduling the MBS PDSCH can be based on nRNTI = 0. This may be the case regardless of whether the pdcch-DMRS-ScramblingID parameter is provided for the controlResourceSet used for the CORESET associated with the search space. In some cases, the RNTI value is equal to 0, and PDCCH DMRS scrambling IDs are not supported for CORESETs associated with the search space. For example, the payload scrambling of a PDCCH used for scheduling MBS PDSCH can be based on n RNTI = 0, and pdcch-DMRS-ScramblingIDs may not be supported for controlResourceSets used for CORESETs associated with the search space.

[0104] In some cases, the value of RNTI can be equal to G-RNTI, and UE 404 can receive the configuration for the PDCCH DMRS scrambling ID for the CORESET associated with the search space. The value of RNTI can also be equal to G-RNTI, and UE 404 may not receive the configuration for the PDCCH DMRS scrambling ID for the CORESET associated with the search space. For example, the payload scrambling of the PDCCH used for the scheduling MBS PDSCH can be based on nRNTI = G-RNTI, regardless of whether a pdcch-DMRS-ScramblingID is provided for the controlResourceSet associated with the CORESET.

[0105] In some configurations, network node 402 can transmit and UE 404 can receive the configuration for the PDCCH DMRS scrambling ID for the CORESET associated with the search space, and based on the configuration of network node 402 transmitting and / or UE 404 receiving the PDCCH DMRS scrambling ID, the value of RNTI can be equal to G-RNTI. In some configurations, UE 404 may not receive the configuration for the PDCCH DMRS scrambling ID for the CORESET associated with the search space, and based on the configuration of network node 402 not transmitting and / or UE 404 not receiving the PDCCH DMRS scrambling ID, the value of RNTI can be equal to 0. For example, if a pdcch-DMRS-ScramblingID is provided for the controlResourceSet for the CORESET associated with the search space, the payload scrambling of the PDCCH used for scheduling MBS PDSCH can be based on n RNTI = G-RNTI, and otherwise based on n RNTI = 0.

[0106] In some configurations, network node 402 can transmit and UE 404 can receive the configuration of the PDCCH DMRS scrambling ID for the CORESET associated with the search space, and network node 402 can transmit and UE 404 can receive a dedicated configuration indication that configures the search space. Based on the network node 402 transmitting and / or UE 404 receiving the configuration of the PDCCH DMRS scrambling ID and the dedicated configuration indication, the value of RNTI can be equal to G-RNTI. In some configurations, network node 402 can transmit and UE 404 can receive a dedicated configuration indication by respectively transmitting and receiving dedicated RRC messages and / or RRC parameters. Based on the determination that network node 402 has not yet transmitted and / or UE 404 has not yet received the configuration of the PDCCH DMRS scrambling ID for the CORESET associated with the search space and the dedicated configuration indication for configuring the search space, the value of RNTI can be equal to 0. For example, if a pdcch-DMRS-ScramblingID is provided for the controlResourceSet used for the CORESET associated with the search space and if the search space is configured by a UE-specific RRC message (or configured with specific RRC parameters), then the payload scrambling of the PDCCH used for scheduling MBS PDSCH can be based on n RNTI = G-RNTI, and otherwise based on n RNTI = 0.

[0107] In some configurations, network node 402 can transmit and UE 404 can receive the configuration for the PDCCH DMRS scrambling ID for the CORESET associated with the search space, and UE 404 can monitor the search space by monitoring the search space only in the RRC connected state. Based on the received configuration of the PDCCH DMRS scrambling ID and the monitoring of the search space only in the RRC connected state, the value of RNTI can be equal to G-RNTI. Based on the determination that network node 402 has not yet transmitted and / or UE 404 has not yet received the configuration for the PDCCH DMRS scrambling ID for the CORESET associated with the search space, and the determination that the search space is not monitored only in the RRC connected state, the value of RNTI can be equal to 0. For example, if a pdcch-DMRS-ScramblingID is provided for the controlResourceSet associated with the search space and if the search space is a search space that is monitored only in the RRC_connected state, then the payload scrambling of the PDCCH used for scheduling MBS PDSCH can be based on n RNTI = G-RNTI, and otherwise based on n RNTI = 0.

[0108] In some configurations, at least one MBS PDCCH communication may include DCI transmission of the scheduled MBS PDSCH. The value of RNTI can be equal to 0 depending on whether the DCI format determining the DCI transmission is DCI format 1_0, and can be equal to G-RNTI depending on whether the DCI format determining the DCI transmission is not DCI format 1_0 (e.g., in the case of DCI format 1_1 or 1_2). For example, if the PDCCH for the scheduled MBS PDSCH is DCI format 1_0, the payload scrambling for the PDCCH used for the scheduled MBS PDSCH can be based on n RNTI = 0, and otherwise based on n RNTI = G-RNTI.

[0109] In some configurations, UE 404 can monitor the search space for at least one MBS PDCCH communication having a CCE index corresponding to a hash function based on the RNTI value, where the RNTI value is equal to G-RNTI or 0. In some configurations, the RNTI value is equal to 0. For example, the hash function used for the search space can be based on n RNTI = 0. In some configurations, the RNTI value can be equal to G-RNTI. For example, the hash function used for the search space can be based on n RNTI = G-RNTI.

[0110] In some configurations, network node 402 can transmit and UE 404 can receive an indication of an RRC parameter that makes RNTI equal to G-RNTI. Based on network node 402 transmitting and / or UE 404 receiving the indication of the RRC parameter, the value of RNTI can be equal to G-RNTI. Based on the decision that network node 402 has not yet transmitted and / or UE 404 has not yet received an indication of an RRC parameter that makes RNTI equal to G-RNTI, the value of RNTI can be equal to 0. For example, if the UE is configured with an RRC parameter that implements n RNTI = G-RNTI, the hash function used for the search space can be based on n RNTI = G-RNTI. If the UE is not configured with an RRC parameter that implements n RNTI = G-RNTI, the hash function can be based on n RNTI = 0.

[0111] In some configurations, network node 402 can transmit and UE 404 can receive a dedicated configuration instruction for configuring the search space, and based on network node 402 transmitting and / or UE 404 receiving the dedicated configuration instruction, the value of RNTI can be equal to G-RNTI. In some configurations, network node 402 can transmit and UE 404 can receive a dedicated configuration instruction by respectively transmitting and receiving dedicated RRC messages and / or dedicated RRC parameters. Based on the determination that network node 402 has not yet transmitted and / or UE 404 has not yet received a dedicated configuration instruction for configuring the search space, the value of RNTI can be equal to 0. For example, in some configurations, if type x CSS is configured by a UE dedicated RRC message (or configured with dedicated RRC parameters), the hash function used for the search space can be based on n RNTI = G-RNTI, and otherwise based on n RNTI = 0.

[0112] In some cases, UE 404 can monitor the search space only in the RRC connected state, and based on this, the RNTI value can be equal to G-RNTI. In other cases, the RNTI value can be equal to 0, based on the determination that the search space is not monitored only in the RRC connected state. For example, if the search space is monitored only in the RRC_connected state, the hash function used for the search space can be based on n RNTI = G-RNTI, and otherwise based on n RNTI = 0.

[0113] In some cases, as described above in conjunction with the scrambling sequence, for a hash function, at least one MBS PDCCH communication may include DCI transmission of the downlink shared channel of the scheduled MBS entity, and the value of RNTI can be equal to 0 depending on whether the DCI format determining the DCI transmission is DCI format 1_0. If the DCI format determining the DCI transmission is not DCI format 1_0, the value of RNTI can be equal to G-RNTI.

[0114] In some configurations, for a downlink cell, UE 404 can utilize multiple G-RNTIs to monitor the PDCCH used for MBS PDSCH. Network node 402 can transmit, and UE 404 can receive, an MBS configuration configured for a plurality of G-RNTIs for the cell; and UE 404 can, based on the MBS configuration, monitor at least one search space of the cell for at least one MBS PDSCH communication scheduled among a plurality of MBS PDSCH communications. Each of the plurality of MBS PDSCH communications can be associated with a corresponding G-RNTI among the plurality of G-RNTIs. For example, different G-RNTIs can be used for different multicast services. At least one G-RNTI among the plurality of G-RNTIs may include the value of an RNTI associated with at least one of the following: a PDCCH payload scrambling sequence, a hash function corresponding to a CCE index, or a CRC scrambling sequence.

[0115] In some states, for example, different G-RNTIs can be used for scrambling, hash functions, and / or CRC scrambling of the DCI for MBS PDSCH associated with different G-RNTIs. In some states, the value of RNTI can be equal to at least one G-RNTI, and at least one additional value of RNTI can be equal to at least one additional G-RNTI among a plurality of G-RNTIs. The value of RNTI can be equal to G-RNTI, and at least one additional payload can be scrambled according to a PDCCH payload scrambling sequence based on at least one additional value of RNTI, wherein at least one additional value of RNTI is equal to at least one additional G-RNTI among a plurality of G-RNTIs. In some states, the value of RNTI can be equal to G-RNTI, and at least one additional CCE index can correspond to at least one additional hash function based on at least one additional value of RNTI, wherein at least one additional value of RNTI is equal to at least one additional G-RNTI among a plurality of G-RNTIs.

[0116] In some states, an RNTI value can be used for scrambling, hashing, and / or CRC scrambling of the DCI for MBS PDSCH associated with different G-RNTIs. For example, in some states, at least one additional value of the RNTI can be equal to the value of the RNTI. At least one additional payload can be scrambled based on a PDCCH payload scrambling sequence based on at least one additional value of the RNTI, where at least one additional value of the RNTI is equal to the value of the RNTI. At least one additional hash function can be based on at least one additional value of the RNTI, where at least one additional value of the RNTI is equal to the value of the RNTI.

[0117] In some configurations, the value of an RNTI can be equal to a specified G-RNTI among a plurality of G-RNTIs. For example, an RNTI can be equal to the lowest and / or the highest value among a plurality of G-RNTIs, as well as other instances. In some configurations, an RNTI can be equal to a specified G-RNTI in a list of G-RNTIs. For example, a list of G-RNTIs can be used to configure a plurality of G-RNTIs, and the value of an RNTI can be equal to the first G-RNTI listed in the list and / or the last G-RNTI listed in the list, as well as other instances. In some configurations, a G-RNTI can be mapped to a specific multicast service (e.g., a multicast service with the lowest and / or highest multicast service ID, as well as other instances of multicast services).

[0118] In some configurations, the RNTI can have a single configurable value. In some configurations, this value can be specifically configurable for a hash function. In some configurations, network node 402 can transmit, and UE 404 can receive, a configuration indicating a configurable specific value for the RNTI. The configurable specific value for the RNTI can be associated with at least one of the following: a PDCCH payload scrambling sequence, a hash function corresponding to a CCE index, or a CRC scrambling sequence. In some configurations, for example, a multicast UE can be configured with a value for the n RNTI, which is used for scrambling, hashing, and / or CRC scrambling of the DCI for the MBS PDSCH associated with different G-RNTIs. The multicast service can include a specified multicast service ID from a plurality of multicast service IDs. In some configurations, the RNTI value can include a configurable specific value.

[0119] In some configurations, where at least one MBS PDCCH communication includes a plurality of MBS PDCCH communications, PDCCHs associated with different G-RNTIs for MBS PDSCHs can be monitored on the same search space set. In some configurations, for example, the mapping from G-RNTI to search space can be one-to-one. In some configurations, PDCCHs associated with different G-RNTIs for MBS PDSCHs can be monitored on different search space sets. For example, the mapping from G-RNTI to search space can be many-to-one. In some configurations, the mapping between G-RNTIs and the search space associated with the PDCCH corresponding to the MBS PDSCH can be configured by RRC signal transmission. For example, network node 402 can transmit, and UE 404 can receive, an RRC configuration indicating the mapping between at least one search space and at least one of the plurality of G-RNTIs.

[0120] As indicated by element symbol 412, network node 402 can transmit and UE 404 can receive at least one MBS PDCCH communication.

[0121] As noted above, Figure 4 is provided as an example. Other examples may differ from those described with respect to Figure 4.

[0122] Figure 5 is a schematic diagram illustrating, for example, an exemplary process 500 performed by a UE according to the content of this case. Exemplary process 500 is an example of a UE (e.g., UE 404) performing an operation associated with PDCCH transmission for MBS service.

[0123] As shown in Figure 5, in some cases, process 500 may include monitoring the search space associated with the PDCCH corresponding to the MBS PDCCH for at least one MBS PDCCH communication having a PDCCH payload scrambled sequence based on the RNTI value, where the RNTI value is equal to G-RNTI or 0 (block 510). For example, a UE (e.g., using the communication manager 140 and / or receiver 1102 illustrated in Figure 11) may monitor the search space for at least one MBS PDCCH communication having a PDCCH payload scrambled sequence based on the RNTI value, where the RNTI value is equal to G-RNTI or 0, as described above.

[0124] As further shown in Figure 5, in some cases, process 500 may include receiving at least one MBS PDCCH communication (block 520). For example, a UE (e.g., using the communication manager 140 and / or receiving element 1102 illustrated in Figure 11) may receive at least one MBS PDCCH communication as described above.
