Description

Technical Field

[0002] In traditional wireless communication, terminals supporting carrier aggregation technology can transmit and receive data on multiple carriers in multiple cells; however, a physical channel transmits on only one carrier. Carrier aggregation technology can enable terminals to obtain greater service bandwidth and higher transmission rates, but it is not efficient in utilizing fragmented spectrum resources.

[0003] Supporting the configuration of multiple carriers in the same serving cell and allowing cross-carrier physical channel transmission in the same serving cell not only enables large service bandwidth and high transmission rate, but also effectively improves the utilization efficiency of fragmented spectrum resources and reduces base station energy consumption.

[0294] Example 3

[0295] 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.

[0296] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for the control plane 300 between the first communication node device (UE, gNB, or RSU in V2X) and the second communication node device (gNB, UE, or RSU in V2X), or between two UEs, is illustrated using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. Layer 1 will be referred to as PHY 301 in this document. Layer 2 (L2 layer) 305, above PHY 301, is responsible for the link between the first and second communication node devices, or between two UEs. Layer 2 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the 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. PDCP sublayer 304 also provides security through encrypted data packets and supports cross-cell mobility between second communication node devices and the first communication node device. RLC sublayer 303 provides upper layer data packet segmentation and reassembly, retransmission of lost data packets, and data packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell between the first communication node devices. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second and first communication node devices. The radio protocol architecture of user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). 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.

Although not illustrated, the first communication node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP 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.).

[0305] Example 4

[0306] 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.

[0307] 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.

[0308] 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.

[0309] 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... The 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 multicarrier symbol stream. The 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 the multi-antenna transmit processor 471 into an RF stream, which is then provided to a different antenna 420.

[0310] 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.

[0311] 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.

[0312] 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.

When multiple carriers among the K carriers satisfy the first condition, the first carrier depends on at least one symbol group among the N symbol groups other than the first symbol group.

[0379] As one embodiment, whether the at least first carrier includes carriers other than the first carrier depends on the bandwidth of the first carrier and the bandwidth of the first frequency domain resource.

[0385] As an example, when the at least first carrier includes carriers other than the first carrier, the first signal occupies at least a portion of the frequency domain resources in each of the at least first carriers.

[0386] As an example, the first node transmits the first signal in the first symbol group only when the first symbol group does not include a symbol configured as downlink by the corresponding information block on at least one of the K carriers.

[0602] Example 15

[0603] Example 15 illustrates a schematic diagram of N symbol groups according to an embodiment of this application; as attached Figure 15As shown. In Embodiment 15, the first signal carries a first transmission block, and the N symbol groups are all allocated to the first transmission block. The N symbol groups are pairwise orthogonal in the time domain. (See Appendix...) Figure 15 In this context, the N symbol groups are respectively represented as symbol group #0, ..., symbol group #(N-1).

[0604] As an example, any one of the N symbol groups includes one or more consecutive symbols.

[0605] As an example, any two symbol groups among the N symbol groups contain the same number of symbols.

[0606] As an example, there are two symbol groups among the N symbol groups that contain unequal numbers of symbols.

[0607] As an example, the first symbol group is any one of the N symbol groups.

[0608] As an example, the first symbol group is any one of the N symbol groups except the first symbol group.

[0609] As an example, the N symbol groups are respectively assigned to the N transmission opportunities of the first transmission block.

[0610] As an example, the N symbol groups are respectively assigned to the N repetitions of the first transport block.

[0611] As an example, the N symbol groups are respectively assigned to the N actual repetitions of the first transport block.

[0612] As an example, the N symbol groups are respectively assigned to the N nominal repetitions of the first transport block.

[0613] As one embodiment, the N symbol groups are divided into W groups, and each of the W groups includes Q = N / W symbol groups, where W and Q are positive integers greater than 1; the W groups are respectively allocated to W transmission opportunities or W repetitions of the first transport block, and any transmission opportunity or any repetition of the first transport block is allocated Q time slots, and the Q symbol groups in any of the W groups are time-domain resources allocated to one transmission opportunity or one repetition of the first transport block in the Q time slots.

[0614] As a sub-implementation of the above embodiments, each transmission opportunity or repetition of the first transmission block is allocated Q consecutive time slots.

[0615] As an example, when multiple carriers among the K carriers satisfy the first condition, the first carrier depends on all symbol groups among the N symbol groups that are no earlier than the first symbol group.

[0616] As an example, when multiple carriers among the K carriers satisfy the first condition, the first carrier depends on all symbol groups among the N symbol groups.

[0617] As an example, when multiple carriers among the K carriers satisfy the first condition, the first carrier depends on all symbol groups among the N symbol groups except the first symbol group.

[0618] As an example, each repetition of the first transport block occupies multiple symbol groups among the N symbol groups. When multiple carriers among the K carriers satisfy the first condition, the first carrier depends on all symbol groups among the N symbol groups that belong to the same repetition of the first transport block as the first symbol group.

[0619] In a preferred embodiment, the first carrier depends on the K information blocks only if the first symbol group is not the first symbol group among the N symbol groups.

[0620] As an example, the carrier occupied by the first transport block in the first symbol group is indicated by the first signaling.

[0621] As an example, the DCI field Carrier indicator of the first signaling indicates the carrier occupied by the first transport block in the first symbol group.

[0622] As an example, the DCI field Bandwidth part indicator of the first signaling indicates the carrier occupied by the first transport block in the first symbol group.

[0623] As an example, the first signaling indicates the carrier occupied by the first transport block in the first symbol group by indicating the BWP.

[0624] As an example, the first signaling indicates the carrier occupied by the first transport block in the first symbol group by indicating frequency domain resource allocation.

[0625] As an example, the carrier occupied by the first transport block in the first symbol group is an uplink carrier connected to the downlink carrier to which the first signaling belongs.

[0626] As an example, the carrier occupied by the first transport block in the first symbol group and the downlink carrier to which the first signaling belongs have the same center frequency.

[0627] As an example, the carrier occupied by the first transport block in the first symbol group and the downlink carrier to which the first signaling belongs have the same identifier and the same center frequency.

[0628] As an example, the carrier occupied by the first transport block in the first symbol group is the currently active uplink carrier.

[0629] As an example, the carrier occupied by the first transport block in the first symbol group is the carrier of the currently active uplink BWP (Bandwidth Part).

[0630] As an example, the carrier occupied by the first transport block in the first symbol group is the carrier with the smallest identifier among the K carriers.

[0631] As an example, the carrier occupied by the first transport block in the first symbol group is a carrier configured with a frequency reference point.

[0632] As an example, only one of the K carriers is configured with a frequency reference point, the first information block indicates the frequency offset between the lowest available subcarrier of the only carrier and the frequency reference point, and the carrier occupied by the first transmission block in the first symbol group is the only carrier.

[0633] As a sub-example of the above embodiment, for any of the K carriers other than the only one carrier, the first information block indicates the absolute frequency of the lowest available subcarrier of that carrier.

[0634] As an example, the first symbol group refers to the earliest symbol group among the N symbol groups.

[0635] Example 16

[0636] Example 16 illustrates a schematic diagram of a first carrier according to an embodiment of this application; as attached Figure 16As shown. In embodiment 16, when multiple carriers among the K carriers satisfy the first condition, the first carrier depends on M symbol groups, the M symbol groups include the first symbol group and at least one symbol group other than the first symbol group among the N symbol groups; among the multiple carriers, the most symbol groups among the M symbol groups on the first carrier satisfy the second condition, the second condition including: excluding symbols configured as downlink by the corresponding information block.

[0637] The advantages of the above method include reducing the number of handovers between different carriers and reducing complexity.

[0638] In the appendix Figure 16 In this context, the plurality of carriers includes a total number of carriers equal to 3, and these carriers are respectively represented as carrier #0, carrier #1, and carrier #2; M equals 4, and the M symbol groups are respectively represented as symbol group #0, symbol group #1, symbol group #2, and symbol group #3. (See Appendix) Figure 16 In (a), the first symbol group is symbol group #0, and the first carrier is carrier #0; in the appendix Figure 16 In (b), the first symbol group is symbol group #2, and the first carrier is carrier #1.

[0639] In the appendix Figure 16 In (a), all M symbol groups on carrier #0 satisfy the second condition; on carrier #1, only symbol groups #0 and #2 satisfy the second condition; on carrier #2, only symbol group #0 satisfies the second condition; therefore, the first carrier is carrier #0.

[0640] As an example, the M symbol groups include each of the N symbol groups that is no earlier than the first symbol group.

[0641] As an example, each repetition of the first transport block is assigned to Q symbol groups from the N symbol groups, the Q symbol groups being located in Q consecutive time slots, and the M symbol groups including all the symbol groups in the N symbol groups that belong to the same repetition of the first transport block as the first symbol group and are no earlier than the first symbol group.

[0642] In the appendix Figure 16 In (b), only symbol groups #2 and #3 on carrier #0 satisfy the second condition; only symbol groups #0, #2 and #3 on carrier #1 satisfy the second condition; only symbol groups #0 and #2 on carrier #2 satisfy the second condition; therefore, the first carrier is carrier #1.

[0643] As an example, the M symbol groups include all the symbol groups in the N symbol groups, where M is equal to N.

[0644] As an example, the M symbol groups include all symbol groups except the first symbol group in the N symbol groups, and M is equal to N-1.

[0645] As an example, each repetition of the first transport block is assigned to Q symbol groups from the N symbol groups, the Q symbol groups being located in Q consecutive time slots, and the M symbol groups including all the symbol groups in the N symbol groups that belong to the same repetition of the first transport block as the first symbol group.

[0650] As an example, the first frequency range is the first carrier wave.

[0651] As an example, the first frequency range is a BWP on the first carrier.

[0652] As an example, the bandwidth of the first frequency range is the number of RBs included in the first frequency range.

[0653] As an example, the first frequency domain resource includes a starting RB0 and a first RB length, and the bandwidth of the first frequency domain resource is equal to the first RB length.

[0654] As an example, the first signal occupies W1 RBs in the first carrier and W2 RBs in the third carrier, the sum of W1 and W2 being equal to the length of the first RB.

[0655] As an example, the first frequency domain resource includes L RBGs, and the bandwidth of the first frequency domain resource is equal to the number of RBs between the highest frequency of the highest RBG and the lowest frequency of the lowest RBG among the L RBGs.

[0656] As an example, the first signal occupies L3 RBGs in the first carrier and L4 RBGs in the third carrier, and the sum of L3 and L4 is equal to L.
