Description

A method and apparatus related to transport blocks used in a node for wireless communication Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for transmitting wireless signals in wireless communication systems supporting cellular networks. Background Technology

[0002] In existing NR (New Radio) systems, spectrum resources are statically divided into FDD (Frequency Division Duplex) and TDD (Time Division Duplex) spectrum. For TDD spectrum, both base stations and UEs (User Equipment) operate in half-duplex mode. This half-duplex mode avoids self-interference and mitigates the impact of cross-link interference (CLI), but it also leads to decreased resource utilization and increased latency. To address these issues, supporting flexible duplex modes or variable link directions (uplink, downlink, or flexible) on TDD or FDD spectrum has become a possible solution. The 3GPP (3rd Generation Partner Project) has agreed to conduct research on duplex technology (especially subband non-overlapping full duplex (SBFD) mode at the gNB (NR Node B) end); optimizing the system design accordingly is an important part of this research.

[0003] Transmitting the same transport block across multiple time slots is an important means of improving transmission reliability in wireless communication. Summary of the Invention

[0004] In systems configured with full-duplex and non-full-duplex symbols, determining the size of the transport block spanning multiple time slots is a critical issue; this application discloses a solution to this problem. It should be noted that this application is applicable to various wireless communication scenarios, such as scenarios using SBFD mode, scenarios using other types of full-duplex modes besides SBFD, and scenarios using more flexible duplex modes, achieving similar technical effects. Furthermore, using a unified solution across different scenarios (including but not limited to scenarios using SBFD mode, scenarios using other types of full-duplex modes besides SBFD, and scenarios using more flexible duplex modes) can help reduce hardware complexity and cost, or improve performance. Unless otherwise specified, embodiments and features in any node of this application can be applied to any other node. Unless otherwise specified, embodiments and features in any node of this application can be arbitrarily combined.

[0005] Where necessary, the interpretation of terms used in this application may be referenced to the descriptions in the 3GPP specification protocols TS37 and TS38 series.

[0006] This application discloses a method used in a first node of wireless communication, characterized by comprising:

[0007] Receive a first signaling message, which indicates the time-domain allocation of multiple resource pools;

[0008] The size of a first transport block is determined and a first operation is performed on the plurality of resource pools, the first operation being either sending or receiving; the first transport block is transmitted on each of the plurality of resource pools, the plurality of resource pools spanning multiple time slots;

[0009] Wherein, the size of the first transport block depends on the target allocation amount, which is based on the PRB allocation for a resource pool of a first type among the plurality of resource pools, where the first type is one of a plurality of types, and the type corresponding to each resource pool among the plurality of resource pools is one of the plurality of types; for one resource pool among the plurality of resource pools, the corresponding type depends on the symbol type of the symbol in the corresponding time-domain allocation, where the symbol type includes at least full-duplex and non-full-duplex.

[0013] As an example, generally speaking, the system configuration on full-duplex symbols and the system configuration on non-full-duplex symbols can be different.

[0102] As an example, the time-domain allocation of each of the plurality of resource pools includes at least one symbol assigned to that resource pool in the time domain.

[0103] As an example, when the time-domain allocation of a resource pool is indicated by a field in a signaling, the signaling indicates the time-domain allocation of the resource pool.

[0104] As an example, the first signaling indicates the time-domain allocation of each of the plurality of resource pools.

[0105] As one embodiment, the first signaling indicates the starting symbol of each of the plurality of resource pools and the number of consecutive symbols counted from the starting symbol.

[0107] As an example, the time slot symbol allocation is the same for any two resource pools of the same type among the plurality of resource pools.

[0108] As an example, the time slot symbol allocation for two of the multiple resource pools can be different.

[0109] As one embodiment, the multiple resource pools span multiple time slots, including: from a time domain perspective, the multiple resource pools are located in different time slots.

[0111] As an example, the plurality of time slots are configurable.

[0113] As one example, the plurality of time slots are arranged sequentially in the time domain.

[0114] As an example, the plurality of time slots are consecutive.

[0115] As an example, the multiple time slots may be discontinuous.

[0116] As one embodiment, the plurality of resource pools are respectively used for multiple repeated transmissions of the first transmission block.

[0117] As one embodiment, each of the plurality of resource pools is used for one repeated transmission of the first transport block.

[0118] As one embodiment, the plurality of resource pools respectively include a plurality of transmission occasions of the first transmission block.

[0119] As one example, the plurality of resource pools correspond one-to-one with the plurality of transmission opportunities of the first transmission block.

[0120] As one embodiment, the first transport block is transported on each of the plurality of resource pools, including: each of the plurality of resource pools is a transport opportunity for the first transport block.

[0121] As an example, in combination with the above features, the solution disclosed in this application is applicable to multiple repeated transmissions of the first transmission block, which is beneficial to improving transmission reliability.

[0122] As an example, a resource pool is allocated for physical layer channels.

[0123] As an example, the plurality of resource pools are all resource pools allocated for PUSCH (Physical Uplink Shared CHannel), and the first operation is transmission.

[0124] As an example, a resource pool is a PUSCH transmission occasion.

[0125] As one embodiment, the plurality of resource pools are each a plurality of PUSCH transmission occasions, and the first operation is to send.

[0126] As an example, the solution disclosed in this application, combined with the above features, is beneficial for improving uplink coverage.

[0127] As one embodiment, the plurality of resource pools are multiple PUSCH transmission opportunities for the first transport block, and the first operation is to send; the first node performs sending on the plurality of resource pools, including: the first node sends the first transport block.

[0128] As an example, the first node sends at least a portion of the first PUSCH in each of the plurality of resource pools.

[0129] As an example, the first node performs a single retransmission of the first PUSCH in each of the plurality of resource pools.

[0130] As an example, the first transport block is sent via the first PUSCH.

[0131] As one embodiment, the first node performs transmission to the plurality of resource pools, including: the first node transmits the first transport block on each of the plurality of resource pools.

[0132] As an example, the first transport block undergoes at least the following processes: CRC attachment, code block segmentation and code block CRC attachment, channel coding, rate matching, code block concatenation, scrambling, modulation, layer mapping, transform precoding, precoding, mapping to virtual resource blocks, and mapping from virtual to physical resource blocks, before being transmitted on one of the plurality of resource pools.

[0133] As an example, the plurality of resource pools are all resource pools allocated for PDSCH (Physical Downlink Shared Channel), and the first operation is receiving.

[0134] As an example, a resource pool is a PDSCH transmission occasion.

[0135] As one embodiment, the plurality of resource pools are respectively a plurality of PDSCH transmission occasions, and the first operation is receiving.

[0136] As one embodiment, the plurality of resource pools are the plurality of PDSCH transmission opportunities of the first transport block, and the first operation is receiving.

[0137] As an example, combined with the above features, the solution disclosed in this application is beneficial to improving the transmission efficiency of the downlink.

[0138] As one embodiment, the plurality of resource pools are a plurality of PDSCH transmission opportunities of the first transport block; the first node performs receiving on the plurality of resource pools, including: the first node receiving the plurality of PDSCH transmission opportunities of the first transport block.

[0139] As one embodiment, the first node performs receiving on the plurality of resource pools, including: the first node receiving the first transport block.

[0140] As one embodiment, the first node performs receiving on the plurality of resource pools, including: the first node performs decoding on the first transport block.

[0141] As one embodiment, the first node performs reception on the plurality of resource pools, including: the first node performs reception once for a first PDSCH on each of the plurality of resource pools.

[0142] As an example, the first transport block is received via the first PDSCH.

[0143] As one embodiment, the first node receives a signal carrying the first transport block on each of the plurality of resource pools, merges all the received signals carrying the first transport block, and performs at least decoding to obtain the first transport block.

[0144] As an example, each of the plurality of resource pools is a resource pool of one of the plurality of types.

[0145] As an example, among the plurality of resource pools, there is at least one resource pool of the first type, and there is at least one resource pool of a type other than the first type among the plurality of types.

[0146] As an example, the features of the above method include: the first transport block is transmitted across full-duplex symbols and non-full-duplex symbols.

[0147] As an example, each of the plurality of resource pools corresponds to only one of the plurality of types.

[0148] As an example, the various types are all types of resource pools.

[0149] As an example, the multiple types are classified according to the symbol types of symbols in the time-domain allocation of a resource pool.

[0150] As an example, the plurality of types includes at least two types.

[0151] As an example, the plurality of types includes only two types.

[0152] As an example, for each of the plurality of resource pools, the corresponding type depends on the symbol type of the symbol in the corresponding time-domain allocation.

[0153] As an example, the target allocation amount is used to determine the size of the first transport block.

[0154] As an example, the target allocation amount is used to determine the size of the first transport block after performing calculations.

[0155] As one embodiment, the target allocation amount is based on the allocation of PRBs for a first type of resource pool among the plurality of resource pools, including: the target allocation amount is the number of PRBs allocated to one resource pool of the first type among the plurality of resource pools.

[0156] As an example, the target allocation amount is the number of PRBs allocated to one of the first type of resource pools among the plurality of resource pools.

[0157] As an example, in conjunction with the above features, the solution disclosed in this application includes the following characteristics: the size of the first transport block does not depend on the number of PRBs allocated to resource pools of other types besides the first type among the plurality of resource pools; such characteristics help reduce the processing complexity of the UE.

[0158] As an example, in combination with the above features, the advantages of the solution disclosed in this application include: it facilitates the optimization of transmission performance through appropriate PRB allocation.

[0159] As one embodiment, the target allocation amount is based on the allocation of PRBs for a first type of resource pool among the plurality of resource pools, including: the target allocation amount is the total number of PRBs allocated to one resource pool of the first type among the plurality of resource pools.

[0160] As an example, the target allocation amount is the total number of PRBs allocated to one of the first type of resource pools among the plurality of resource pools.

[0161] As an example, determining the size of the first transport block includes determining the total number of target REs, which is equal to a positive integer multiple of the target allocation.

[0162] As an example, all symbols in the time-domain allocation of one of the multiple resource pools are full-duplex symbols, or all symbols in the time-domain allocation of one of the multiple resource pools are non-full-duplex symbols.

[0163] As an example, the advantages of the above method include further reducing the complexity of system design.

[0164] As an example, when at least one symbol in the time-domain allocation of one of the plurality of resource pools is a full-duplex symbol, this resource pool is a resource pool of a type other than the first type among the plurality of types; when all symbols in the time-domain allocation of one of the plurality of resource pools are non-full-duplex symbols, this resource pool is a resource pool of the first type.

[0165] As a sub-implementation of the above embodiment, the target allocation amount is the total number of PRBs allocated to one of the resource pools of the first type among the plurality of resource pools.

[0166] As an example, in SBFD mode, the available frequency domain allocation range in non-full-duplex symbols is likely to be larger than that in full-duplex symbols; correspondingly, for transport blocks transmitted across full-duplex and non-full-duplex symbols, the number of PRBs allocated in non-full-duplex symbols is also likely to be greater than the number of PRBs allocated in full-duplex symbols; the above method allows the size of transport blocks transmitted across full-duplex and non-full-duplex symbols to always be determined according to the number of PRBs allocated in non-full-duplex symbols, which is beneficial to improving data transmission rate or resource utilization.

[0167] As an example, the plurality of types includes only the first type and the second type; the number of PRBs allocated to one resource pool of the first type in the plurality of resource pools is greater than the number of PRBs allocated to one resource pool of the second type in the plurality of resource pools.

[0168] As an example, the plurality of types includes only the first type and the second type; the total number of PRBs allocated to one resource pool of the first type in the plurality of resource pools is greater than the total number of PRBs allocated to one resource pool of the second type in the plurality of resource pools.

[0169] As an example, when at least one symbol in the time-domain allocation of one of the plurality of resource pools is a full-duplex symbol, this resource pool is a resource pool of the first type; when all symbols in the time-domain allocation of one of the plurality of resource pools are non-full-duplex symbols, this resource pool is a resource pool of a type other than the first type among the plurality of types.

[0170] As an example, compared to non-full-duplex symbols, the interference between uplink and downlink is usually more severe in full-duplex symbols; for transport blocks transmitted across full-duplex and non-full-duplex symbols, the above method determines the size of the transport block according to the PRB allocation for full-duplex symbols; this feature is more conducive to ensuring the lower limit of transmission performance and enhancing the stability of the system.

[0171] As an example, the plurality of types includes only the first type and the second type; the number of PRBs allocated to one resource pool of the first type in the plurality of resource pools is less than the number of PRBs allocated to one resource pool of the second type in the plurality of resource pools.

[0172] As an example, the plurality of types includes only the first type and the second type; the total number of PRBs allocated to one resource pool of the first type in the plurality of resource pools is less than the total number of PRBs allocated to one resource pool of the second type in the plurality of resource pools.

[0173] As an example, the size of the first transport block depends on the target allocation only when the number of resource pools of the first type in the plurality of resource pools exceeds one-third of the total number of resource pools in the plurality of resource pools.

[0174] As an example, the plurality of types includes only the first type and the second type; when the number of resource pools of the first type in the plurality of resource pools does not exceed one-third of the total number of resource pools in the plurality of resource pools, the size of the first transport block does not depend on the target allocation amount; at this time, the method for determining the size of the first transport block is almost the same as the method for determining the size when the number of resource pools of the first type in the plurality of resource pools exceeds one-third of the total number of resource pools in the plurality of resource pools, the only difference being that the target allocation amount is replaced by the total number of PRBs allocated to one resource pool of the second type in the plurality of resource pools.

[0175] As an example, the size of the first transport block depends on the target allocation only when the number of resource pools of the first type in the plurality of resource pools exceeds half of the total number of resource pools in the plurality of resource pools.

[0176] As an example, the plurality of types includes only the first type and the second type; when the number of resource pools of the first type in the plurality of resource pools does not exceed half of the total number of resource pools in the plurality of resource pools, the size of the first transport block does not depend on the target allocation amount; at this time, the method for determining the size of the first transport block is almost the same as the method for determining the size when the number of resource pools of the first type in the plurality of resource pools exceeds half of the total number of resource pools in the plurality of resource pools, the only difference being that the target allocation amount is replaced by the total number of PRBs allocated to one resource pool of the second type in the plurality of resource pools.

[0177] As an example, the first type is determined according to the indication of the first signaling.

[0178] As an example, the first type is the type corresponding to the first resource pool among the plurality of resource pools.

[0179] As an example, the first type is the type corresponding to the earliest resource pool among the plurality of resource pools.

[0180] As an example, after defining the above features, the base station can implicitly indicate the first type by scheduling the multiple resource pools; such a feature is beneficial to improving the transmission efficiency of the transport block.

[0181] As an example, the advantages of the above method include: the above implicit indication does not require additional overhead to indicate the first type.

[0182] As an example, the first type is the type corresponding to the last resource pool among the plurality of resource pools.

[0183] As an example, the first type is the type corresponding to the latest resource pool among the plurality of resource pools.

[0184] As an example, after defining the above features, the base station can implicitly indicate the first type by scheduling the multiple resource pools; such a feature is beneficial to improving the transmission efficiency of the transport block.

[0185] As an example, the advantages of the above method include: the above implicit indication does not require additional overhead to indicate the first type.

[0186] As an example, the first type is which of the plurality of types is configured by higher-layer signaling.

[0187] As an example, the first type is which of the plurality of types is configured by RRC signaling.

[0188] As an example, the PRB allocations corresponding to any two resource pools of the same type among the plurality of resource pools are the same.

[0189] As an example, the PRB allocations corresponding to two different types of resource pools among the multiple resource pools can be different.

[0190] As an example, there are two different types of resource pools among the multiple resource pools, and the PRB allocations corresponding to these two resource pools are different.

[0191] As an example, the target allocation amount is the total number of PRBs allocated to one of the resource pools of the first type among the plurality of resource pools; the determination of the size of the first transport block includes the determination of the target total number of REs, which is equal to a positive integer multiple of the target allocation amount.

[0192] As an example, the target allocation amount is the number of PRBs allocated to one of the resource pools of the first type among the plurality of resource pools; the determination of the size of the first transport block includes the determination of the target total number of REs, which is equal to a positive integer multiple of the target allocation amount.

[0193] As an example, the size of the first transport block is equal to the product of the result of rounding down to the 1.7th power of the target allocation amount and the result of rounding down to the 0.6th power of the number of time-domain symbol allocations indicated by the first signaling.

[0194] As an example, the size of the first transport block is equal to The product of the result of rounding up to the 1.6th power of the number of symbols allocated in the time domain indicated by the first signaling; wherein, P1 is the target allocation amount.

[0195] As an example, the symbol types include at least full-duplex and non-full-duplex, including: a symbol's symbol type is either full-duplex or non-full-duplex.

[0196] As an example, the symbol type of a full-duplex symbol is full-duplex, and the symbol type of a non-full-duplex symbol is non-full-duplex.

[0197] As an example, there is no symbol that is both a full-duplex symbol and a non-full-duplex symbol.

[0198] As an example, when a symbol is indicated by uplink / downlink TDD configuration signaling as downlink and available for uplink transmission, the symbol is a full-duplex symbol.

[0199] As an example, the advantages of the above method include: it helps to improve uplink capacity.

[0200] As an example, when a symbol is not a full-duplex symbol, it is a non-full-duplex symbol.

[0201] As an example, when a symbol is indicated as an uplink by uplink / downlink TDD configuration signaling, the symbol is a non-full-duplex symbol.

[0202] As an example, when a symbol is configured to be used for full-duplex operation, the symbol is a full-duplex symbol; when a symbol is configured not to be used for full-duplex operation, the symbol is a non-full-duplex symbol.

[0203] As an example, a symbol is a full-duplex symbol when it is configured to be used for full-duplex operation; a symbol is a non-full-duplex symbol when it is not configured to be used for full-duplex operation.

[0204] As an example, the symbol used for SBFD operation is a full-duplex symbol, not a non-full-duplex symbol.

[0205] As an example, the symbol not used for SBFD operations is a non-full-duplex symbol, not a full-duplex symbol.

[0206] As an example, SBFD symbols are full-duplex symbols, and non-SBFD symbols are non-full-duplex symbols.

[0207] As an example, all symbols in a full-duplex time slot are full-duplex symbols.

[0208] As an example, all symbols in a non-full-duplex time slot are non-full-duplex symbols.

[0221] Example 3

[0222] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and control plane according to this application, as shown in Figure 3. Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3 shows the radio protocol architecture for a first communication node device (UE, gNB, or V2X (Vehicle to Everything) RSU (Road Side Unit), on-board equipment, or on-board communication module) and a second communication node device (gNB, UE, or V2X RSU, on-board equipment, or on-board communication module), or the control plane 300 between two UEs, using three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 will be referred to herein as PHY301. Layer 2 (L2) 305 sits above PHY 301 and is responsible for the link between the first and second communication node devices and between the two UEs via PHY 301. L2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and supports cross-region mobility between the second and first communication node devices. The RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat Request). MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among the first communication node devices. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in L3 of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second and first communication node devices.The radio protocol architecture of user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture for the first and second communication node devices in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for Physical Layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355, and MAC sublayer 352 in L2 layer 355.

L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS (Quality of Service) streams and Data Radio Bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above the L2 layer 355, including a network layer (e.g., the IP (Internet Protocol) layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.).

[0227] Example 4

[0228] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to this application, as shown in Figure 4. Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0229] 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.

[0230] 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.

[0231] 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 the transmission from the first communication device 410 to the second communication device 450, 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 retransmitting 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 the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), 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 to generate one or more spatial streams. Transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it 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 multicarrier symbol 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 a different antenna 420.

[0232] 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 spatial stream destined for the second communication device 450. Symbols on each spatial 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 by the first communication device 410 over the physical channel. 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. 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 transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0233] 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 transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting 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 spatial 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.

[0234] 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. In the transmission from the second communication device 450 to the first communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.
