Description

Technical Field

[0001] This application relates to methods and apparatus in wireless communication systems, and more particularly to schemes and apparatus related to channel information of user equipment in wireless communication systems. Background Technology

[0002] In traditional wireless communication, the UE (User Equipment) reports various auxiliary information obtained through measurements of downlink signals and / or channels, such as channel information, beam management-related auxiliary information, positioning-related auxiliary information, etc. CSI (Channel Status Information) includes, but is not limited to, one or more of CRI (CSI-RS Resource Indicator), RI (Rank Indicator), PMI (Precoding Matrix Indicator), or CQI (Channel Quality Indicator). The UE can use this information to select appropriate transmission parameters or report this information. The network device selects appropriate transmission parameters for the UE based on the UE's reports, such as the cell to be used, MCS (Modulation and Coding Scheme), TPMI (Transmitted Precoding Matrix Indicator), TCI (Transmission Configuration Indication), etc. In addition, UE reports can be used to optimize network parameters, such as better cell coverage, switching base stations on and off based on UE location, and so on.

[0003] With the adoption of new technologies, the increase in the number of antennas, the diversification of application scenarios, and the increasing demands on system performance, traditional measurement and reporting methods incur significant redundancy overhead. Therefore, in NR (New Radio) Rel-18 (Release-18), research on AI (Artificial Intelligence) / ML (Machine Learning) technologies was initiated to explore their impact on system performance and design. Compared to traditional processing methods, AI / ML offers advantages such as training-based and deployment-required features. Based on current research progress, the AI / ML model on the UE side can be trained and stored on the UE's dedicated server. AI / ML technology may also play a crucial role in future 6G communications. However, according to 3GPP (3rd Generation Partnership Project) standard TS (Technical Specification) 38.300, AI / ML models and algorithms extend beyond the scope of 3GPP. Summary of the Invention

[0223] Example 2

[0224] Example 2 illustrates a schematic diagram of a network architecture according to an embodiment of this application, as shown in the accompanying drawings, wherein,

[0225] Appendix Figure 2(a) describes the network architecture 200. The network architecture 200 is a 5G NR (New Radio) / LTE (Long-Term Evolution) / LTE-A (Long-Term Evolution Advanced) system, or a 5G+ network architecture, or a 6G network architecture, or a network architecture adopted in the future evolution of 3GPP; the network architecture 200 may be referred to as 5GS (5G System) / EPS (Evolved Packet System), or 6GS (6G System); the network architecture 200 includes at least one of UE (User Equipment) 201, RAN (Radio Access Network) 202, core network 210, HSS (Home Subscriber Server) / UDM (Unified Data Management) 220, and Internet service 230. The network architecture 200 can interconnect with other access networks, but these entities / interfaces are not shown for simplicity. As shown, the network architecture 200 provides packet-switched services; however, those skilled in the art will readily understand that the various concepts presented throughout this application can be extended to networks providing circuit-switched services or other cellular networks. The RAN includes node 203. The RAN may also include other nodes 204. Node 203 provides user and control plane protocol termination toward UE 201. Node 203 may be connected to other nodes 204 via an Xn interface (e.g., backhaul) / X2 interface. Node 203 may also be referred to as a base station, base transceiver station, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), TRP (transmitter-receiver node), or some other suitable term. The core network 210 is a 5GC (5G Core Network) / EPC (Evolved Packet Core), or the core network 210 is a 6GC; node 203 provides UE 201 with an access point to the core network 210.Examples of UE201 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, non-terrestrial base station communications, satellite mobile communications, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, drones, aircraft, narrowband IoT devices, machine-type communication devices, land vehicles, automobiles, wearable devices, mobile terminals (MTs) in relay equipment, or any other similar functional devices. Those skilled in the art may also refer to UE201 as a mobile station, subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio communication device, remote device, mobile subscriber station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or any other suitable term. Node 203 is connected to the core network 210 via an S1 / NG interface. The core network 210 includes MME (Mobility Management Entity) / AMF (Access and Mobility Management Function) / SMF (Session Management Function) 211, other MME / AMF / SMF 214, S-GW (Service Gateway) / UPF (User Plane Function) 212, and P-GW (Packet Data Network Gateway) / UPF 213, as well as others not listed above. Figure 2 The node shown in (a) is the MME / AMF / SMF211, which is the control node for handling signaling between UE201 and the core network 210. Generally, the MME / AMF / SMF211 provides bearer and connection management. All user IP (Internet Protocol) packets are transmitted through the S-GW / UPF212, which is itself connected to the P-GW / UPF213. The P-GW / UPF213 provides UE IP address allocation and other functions. The P-GW / UPF213 is connected to the Internet service 230. The Internet service 230 includes operator-compliant Internet Protocol services, specifically including the Internet, intranet, IMS (IP Multimedia Subsystem), and packet switching services.

[0226] For ease of description, please attach Figure 2(b) Further examples illustrate the application of the core network 210 in the 5G network architecture as a Network Function (NF). The NF may include, but is not limited to, the following: UPF 240, NEF (Network Exposure Function) 241, NRF (Network Repository function) 242, PCF (Policy Control Function) 243, UDM 244, UDR (Unified Data Repository) 245, NWDAF (Network Data Analytics Function) 246, AUSF (Authentication Server Function) 247, AMF 248, SMF 249, DN (Data Network) 250 (also known as PDN (Packet Data Network)), and AF (Application Function) 251.

[0227] The following is a brief explanation of the above NF.

[0228] 1. The UPF240 is a gateway provided by the operator, serving as the gateway for communication between the operator's network (such as a PLMN (Public Land Mobile Network)) and the data network DN250. The UPF240 includes user plane-related functions such as packet routing and transmission, packet inspection, service usage reporting, QoS (Quality of Service) processing, lawful interception, uplink packet inspection, and downlink packet storage.

[0229] 2. NEF241 is a control plane function provided by the operator, which mainly enables third parties to use the services provided by the network. It supports the network to open its capabilities, events and data analysis, provide security configuration information to the PLMN from external applications, convert information exchanged between the PLMN and external networks, provide APIs (Application Programming Interfaces) exposed by the operator network, and provide interaction between external servers and the internal operator network.

[0230] 3. NRF242 is a control plane function provided by the operator, which can be used to maintain real-time information about network functions and services in the network. For example, it supports network service discovery, maintains the services supported by the NF configuration data (NF Profile) of NF instances, supports service discovery of SCP (Service Communication Proxy), maintains the SCP configuration data (SCP Profile) of SCP instances, sends notifications about newly registered, deregistered, and updated NFs and SCPs, and maintains the health status of NFs and SCPs.

[0231] 4. PCF243 is a control plane function provided by the operator. It supports a unified policy framework to govern network behavior, provide policy rules and subscription information related to policy decisions to other control functions, etc.

[0232] 5. UDM244 is a control plane function provided by the operator, responsible for storing information such as the SUPI (Subscription Permanent Identifier), GPSI (Generic Public Subscription Identifier), and Credential of subscribed users in the operator's network. The SUPI is encrypted during transmission; the encrypted SUPI is called SUCI (Subscription Concealed Identifier). This information stored in UDM244 can be used for UE201 authentication and authorization when accessing the operator's network. The subscribed users in the aforementioned operator network can specifically be users of services provided by the operator's network. The Credential of the subscribed user can be a long-term key stored in the SIM card (e.g., SIM (Subscriber Identity Module) card) or a small file containing information related to SIM card encryption, used for authentication and / or authorization.

[0233] 6. UDR245 is a control plane function provided by the operator, which provides UDM244 with the function of storing and retrieving subscription data, PCF243 with the function of storing and retrieving policy data, and storing and retrieving user NF group ID information, etc.

[0234] 7. NWDAF246 is a control plane function provided by the operator. Its main function is to collect data from NF, external application function AF, and OAM (Operations Administration and Maintenance) system, and provide NWDAF service registration, data access, and analysis data to NF and AF. In this application, NWDAF is mainly responsible for data analysis related to AI / ML functions. Therefore, in this application, NWDAF can also be understood as a network element with analysis functions for AI / ML functions. The name NWDAF is just an example, and other network element names may be used later. This application does not limit this.

[0235] 8. AUSF247 is a control plane function provided by the operator, typically used for Level 1 authentication, i.e., authentication between UE201 (the subscribed user) and the operator's network. After receiving an authentication request from the subscribed user, AUSF247 can authenticate and / or authorize the subscribed user using the authentication and / or authorization information stored in UDM244, or generate the subscribed user's authentication and / or authorization information using UDM244. AUSF247 can then send the authentication and / or authorization information back to the subscribed user.

[0236] 9. The AMF248 is a control plane network function provided by the operator's network, responsible for access control and mobility management of UE201's access to the operator's network. This includes functions such as mobility state management, assigning temporary user identities, authenticating and authorizing users. The AMF248 is used for NAS (Non-Access Stratum) connections with UE201 and has the same 5G NAS security context as UE201.

[0237] 10. SMF249 is a control plane network function provided by the operator's network, responsible for managing the PDU (Protocol Data Unit) sessions of UE201. A PDU session is a channel used to transmit PDUs; terminal equipment needs to exchange PDUs with the data network DN250 through PDU sessions. SMF249 is responsible for establishing, maintaining, and deleting PDU sessions. SMF249 includes session management (e.g., session establishment, modification, and release, including tunnel maintenance between UPF240 and RAN202), UPF240 selection and control, SSC (Service and Session Continuity) mode selection, roaming, and other session-related functions.

[0238] 11. DN250 is typically a network located outside the operator's network, such as a third-party network. However, in some implementations, the DN can also be deployed by the operator, meaning the DN is part of the PLMN. This application does not restrict whether the DN belongs to the PLMN. The operator's network can access multiple data networks DN250. Various services can be deployed on the data network DN250, providing data and / or voice services to UE201. UE201 can establish a connection with the operator's network through an interface provided by the operator's network (e.g., the N1 interface) and use the data and / or voice services provided by the operator's network. UE201 can also access the data network DN250 through the operator's network and use operator services deployed on the data network DN250, and / or services provided by third parties.

[0239] 12. AF251 is a control plane network function provided by the operator's network. It is used to provide application layer information and can interact with the policy framework, either directly or through network open function elements, to make policy decision requests. It can be located within or outside the operator's network.

[0240] It is understandable that the aforementioned network elements or functions can be physical entities in hardware devices, software instances running on dedicated hardware, or virtualization functions instantiated on a shared platform (e.g., a cloud platform). Simply put, an NF can be implemented in hardware or software.

[0241] Appendix Figure 2 (b) In this diagram, Nnef, Nnrf, Npcf, Nudm, Nudr, Nnwdaf, Nausf, Namf, Nsmf, Naf, N4, and N6 are interface sequence numbers. For example, the meanings of these interface sequence numbers can be found in the 3GPP standard protocols, and this application does not limit the meaning of these interface sequence numbers. It should be noted that the interface names between the various network functions in the diagram are merely examples; in specific implementations, the interface names of this system architecture may be other names, and this application does not limit them. Furthermore, the names of the messages (or signaling) transmitted between the various network elements are also merely examples and do not constitute any limitation on the function of the messages themselves.

[0242] For ease of explanation, in the embodiments of this application, network functions (such as UPF240 to AF251) are collectively referred to as NF, that is, the NF described below in the embodiments of this application can be replaced by any network function. In addition, the appendix Figure 2 (b) Only a portion of the network functions are illustrated; the NFs described below are not limited to those shown in the appendix. Figure 2 The network functionality shown in (b) is described.

[0243] It should be understood that the network architecture described above in the embodiments of this application is only a network architecture described from the perspective of service-oriented architecture. The network architecture applicable to the embodiments of this application is not limited to this. Any network architecture that can implement the functions of the above-mentioned NFs is applicable to the embodiments of this application.

[0244] It should also be understood that, attached Figure 2 (b) The AMF, SMF, UPF, NEF, AUSF, NRF, PCF, and UDM shown can be understood as network elements in the core network used to implement different functions, such as network slicing that can be combined as needed. These core network elements can be independent devices or integrated into the same device to implement different functions. This application does not limit the specific form of the above network elements.

[0245] It should also be understood that the above naming is defined solely for the purpose of distinguishing different functions and should not constitute any limitation on this application. This application does not preclude the possibility of using other naming conventions in 5G networks and other future networks. For example, in 6G networks, some or all of the above-mentioned network elements may use the terminology from 5G, or may use other names, etc.

[0255] Example 3

[0256] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in the attached diagram. Figure 3 As shown, Figure 3 This is a schematic diagram illustrating an embodiment of the radio protocol architecture used for the user plane 350 and the control plane 300. It should be noted that... Figure 3 Primarily targeting 5G / NR system standards, but Figure 3 Some or all of these aspects may also be applicable to other wireless communication network systems.

[0257] The PHY (Physical) sublayer 301 can transmit and receive physical layer signals, which can be received from or transmitted to one or more other communication devices. Physical layer signals may include one or more physical channels. The PHY sublayer 301 can also perform link adaptation or AMC (Adaptive Modulation and Coding), power control, cell search (e.g., for initial synchronization and handover purposes), and other measurements used by higher layers (e.g., RRC (Radio Resource Control) sublayer 315). The PHY sublayer 301 can further perform error detection on the transport channel, FEC (Forward Error Correction) encoding / decoding of the transport channel, modulation / demodulation of the physical channel, interleaving, rate matching, mapping to the physical channel, and MIMO (Multiple Input Multiple Output) antenna processing. In an embodiment, an instance of the PHY sublayer 301 can process requests from an instance of the MAC (Medium Access Control) sublayer 302 and provide it with instructions. According to some implementation schemes, the requests and instructions sent by the PHY sublayer 301 to the MAC sublayer 302 may include one or more transport channels.

[0258] An instance of MAC sublayer 302 can process requests from an instance of RLC (Radio Link Control) sublayer 303 and provide it with instructions. These requests and instructions sent by MAC sublayer 302 to RLC sublayer 303 may include one or more logical channels. MAC sublayer 302 can perform mapping between logical channels and transport channels, multiplexing MAC SDUs (Service Data Units) from one or more logical channels onto a TB (Transport Block) to be delivered to PHY sublayer 301 via the transport channel, demultiplexing MAC SDUs from a TB delivered from PHY sublayer 301 via the transport channel onto one or more logical channels, multiplexing MAC SDUs onto TBs, scheduling information reporting, error correction via HARQ (Hybrid Automatic Repeat Request), and prioritizing logical channels.

[0259] An instance of RLC sublayer 303 can process requests from an instance of PDCP (Packet Data Convergence Protocol) sublayer 304 and provide it with instructions. These requests and instructions sent by RLC sublayer 303 to PDCP sublayer 304 may include one or more logical channels. RLC sublayer 303 can operate in several modes, including: Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM). RLC sublayer 303 can perform transmission of upper-layer PDUs (Protocol Data Units), error correction via ARQ (Automatic Repeat Request) for AM data transmission, and concatenation, segmentation, and reassembly of RLC SDUs for UM and AM data transmission. RLC sublayer 303 can also re-segment RLC data PDUs used for AM data transmission, reorder RLC data PDUs used for UM and AM data transmission, detect duplicate data used for UM and AM data transmission, discard RLC SDUs used for UM and AM data transmission, detect protocol errors used for AM data transmission, and perform RLC re-establishment.

[0260] An instance of PDCP sublayer 304 can handle requests from instances of RRC sublayer 315 and / or SDAP (Service Data Adaptation Protocol) sublayer 325 and provide them with instructions. These requests and instructions sent by PDCP sublayer 304 to SDAP sublayer 325 may include one or more RBs (Radio Bearers). PDCP sublayer 304 can perform header compression and decompression of IP data, maintain PDCP SN (Sequence Number), perform sequential delivery of upper-layer PDUs during lower-layer re-establishment, eliminate duplication of lower-layer SDUs during lower-layer re-establishment for RBs mapped on RLC AM, encrypt and decrypt control plane data, perform integrity protection and integrity verification on control plane data, control timer-based data discarding, and perform security operations (e.g., encryption, decryption, integrity protection, integrity verification, etc.).

[0261] An instance of SDAP sublayer 325 can process requests from one or more higher-layer protocol entities and provide them with indications. These requests and indications sent by SDAP sublayer 325 to higher-layer protocol entities may include one or more QoS (Quality of Service) flows. SDAP sublayer 325 can map QoS flows to DRBs (Data Radio Bearers) and vice versa, and can also tag QFIs (QoS Flow IDs) in DL (downlink) and UL (uplink) packets. A single SDAP entity can be configured for a single PDU session. In the UL direction, NG-RAN nodes (e.g., node 203 in embodiment 2) can control the mapping of QoS flows to DRBs in two different ways (reflective mapping or explicit mapping). For reflective mapping, SDAP sublayer 325 can monitor the QFI of DL packets for each DRB and can apply the same mapping for packets flowing in the UL direction. To implement reflective mapping, NG-RAN nodes can tag DL packets with QFIs via the Uu interface. Explicit mapping may involve the RRC sublayer 315 configuring the SDAP sublayer 325 with explicit mapping rules for QoS flows to the DRB. These rules may be stored and followed by the SDAP sublayer 325. In implementations, the SDAP sublayer 325 may be used only in NR implementations and may not be used in LTE implementations.

[0262] RRC sublayer 315 can be configured with aspects of one or more protocol layers, which may include one or more instances of PHY sublayer 301, MAC sublayer 302, RLC sublayer 303, PDCP sublayer 304, and SDAP sublayer 325. In an implementation, an instance of RRC sublayer 315 may process requests from one or more NAS (Non-Access Stratum) sublayers 316 and provide them with instructions. The main services and functions of RRC sublayer 315 may include broadcasting system information (e.g., MIB (Master Information Block) or SIB (System Information Block)), paging, establishment, maintenance, and release of RRC connections between the UE and NG-RAN nodes (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), establishment, configuration, maintenance, and release of point-to-point RBs, security functions including key management, mobility between RATs (Radio Access Technology), and measurement configuration for UE measurement reporting. These MIBs and SIBs may include one or more IEs, each of which may include a separate data field or data structure.

[0263] NAS sublayer 316 forms the highest layer of the control plane between the UE and the AMF. NAS sublayer 316 supports the UE's mobility and session management procedures to establish and maintain IP connections between the UE and the application layer in the NR system.

[0264] As one embodiment, the control plane protocol stack may include, in order from highest to lowest layer, NAS sublayer 316, RRC sublayer 315, PDCP sublayer 304, RLC sublayer 303, MAC sublayer 302, and PHY sublayer 301. In this example, the upper control plane layer may be built on top of NAS sublayer 316, and this upper control plane layer includes IP sublayer 317, SCTP (Stream Control Transmission Protocol) sublayer 318, and AP (Application Protocol) sublayer 319.

[0265] In a specific NR implementation, AP sublayer 319 can be NGAP (NG Application Protocol) for the NG interface between NG-RAN nodes and AMF, or AP sublayer 319 can be XnAP (Xn Application Protocol) for the Xn interface between two or more NG-RAN nodes.

[0266] NGAP can support the functionality of the NG interface. NGAP services can include two groups: UE-associated services (e.g., services related to the UE) and non-UE-associated services (e.g., services related to the entire NG interface instance between the NG-RAN node and the AMF). These services may include, but are not limited to: paging functions for sending paging requests to NG-RAN nodes involved in a specific paging area; UE context management functions for allowing the AMF to establish, modify, and / or release UE contexts in the AMF and NG-RAN nodes; mobility functions for UEs in ECM-CONNECTED mode, enabling intra-system handover (HO) to support mobility within the NG-RAN and inter-system HO to support mobility from / to EPS systems; NAS signaling transmission functions for transmitting or rerouting NAS messages between the UE and AMF; NAS node selection functions for determining the association between the AMF and the UE; NG interface management functions for setting up the NG interface and monitoring for errors via the NG interface; warning message transmission functions for providing means of transmitting warning messages or canceling ongoing warning message broadcasts via the NG interface; configuration transmission functions for requesting and transmitting RAN configuration information (e.g., SON (Self-Organizing Network) information, etc.) between two NG-RAN nodes via the core network (e.g., core network 210 in Embodiment 2); and / or other similar functions.

[0267] XnAP supports the functions of the Xn interface and can include XnAP basic mobility procedures and XnAP global procedures. XnAP basic mobility procedures can include processes for handling UE mobility within the NG-RAN, such as handover preparation and cancellation procedures, SN state transmission procedures, UE context retrieval and UE context release procedures, RAN paging procedures, and procedures related to dual connectivity. XnAP global procedures can include procedures associated with non-UEs, such as Xn interface setup and reset procedures, NG-RAN update procedures, and cell activation procedures.

[0268] SCTP sublayer 318 provides guaranteed delivery of application layer messages (e.g., NGAP or XnAP messages). SCTP sublayer 318 can, in part, rely on the IP protocol supported by IP sublayer 317 to ensure reliable delivery of signaling messages between NG-RAN nodes and AMF or other NG-RAN nodes. IP sublayer 317 can be used to perform packet addressing and routing functions, assigning IP addresses to user data packets in formats such as IPv4 (Internet Protocol version 4), IPv6 (Internet Protocol version 6), or PPP (Point to Point Protocol). In some implementations, IP sublayer 317 can use point-to-point transport to deliver and send PDUs.

[0269] As one embodiment, the user plane protocol stack may include, in order from highest to lowest layer, SDAP sublayer 325, PDCP sublayer 304, RLC sublayer 303, MAC sublayer 302, and PHY sublayer 301. The user plane protocol stack can be used for communication between the UE, NG-RAN nodes, and UPF in a specific NR implementation. In this example, the user plane upper layer may be built on top of SDAP sublayer 325 and may include UDP (User Datagram Protocol) sublayer 327, IP sublayer 326, GTP-U (General Packet Radio Service Tunneling Protocol Userplane) sublayer 328, and User Plane (PDUs) sublayer 329. The GTP-U sublayer 328 can be used to carry user data between NG-RAN nodes and the core network, or between NG-RAN nodes. UDP sublayer 327 and IP sublayer 326 provide verification for data integrity and port numbers for addressing different functions at the source and destination, as well as encryption and authentication for the selected data stream. GTP-U sublayer 328 can be used on top of UDP sublayer 327 and IP sublayer 326 to carry User Plane PDUs sublayer 329.

[0270] Furthermore, despite Figure 3 Not shown, but the Application layer may exist above the AP sublayer 319 and / or the UserPlane PDUs sublayer 329.

[0282] Example 4

[0283] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown. (Attached) Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0284] The first communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0285] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0286] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In DL (Downlink), the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operation, retransmission of lost packets, and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for L1 layer (i.e., physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and constellation mapping based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), and M-quadrature amplitude modulation (M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, generating one or more... Parallel streams. Transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain O-stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by multi-antenna transmit processor 471 into an RF stream, which is then provided to different antennas 420.

[0287] In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any parallel stream destined for the second communication device 450. Symbols on each parallel stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted over the physical channel by the first communication device 410. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2 (L2). The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the DL (Layered Logic), the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer packets from the core network. The upper-layer packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 (L3) for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0288] In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the first communication device 410 described in the DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communication device 410, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated parallel stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0289] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function at the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. The controller / processor 475 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer data packets from the second communication device 450. The upper-layer data packets from the controller / processor 475 may be provided to the core network. The controller / processor 475 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.
