Description

Method and apparatus for wireless communication

Technical Field

The present application relates to a method and apparatus in a wireless communication system, and more particularly, to a method and apparatus for supporting scheduling when L1/L2 (Layer 1/Layer 2) mobility enhancement in wireless communication.

Background

When a UE (User Equipment) moves from the coverage of one cell to the coverage of another cell, the serving cell of the UE needs to be changed. Existing serving cell changes are typically triggered by L3 (Layer 3 ) measurements, through RRC (Radio Resource Control ) signaling triggered reconfiguration (Reconfiguration with Synchronization) including synchronization. The serving cell change implemented at L3 has the characteristics of long delay time, large signaling overhead and long interruption time. To overcome the above drawbacks, the 3GPP (3 rd Generation Partner Project, third generation partnership project) RAN (Radio Access Network ) introduces dual connectivity (Dual Connectivity, DC) in Rel (release) -17, techniques of conditional PSCell change (Conditional PSCell (Primary SCG (Secondary Cell Group) Cell) change, CPC), conditional PSCell Addition (CPA), conditional handover (Conditional Handover, CHO), etc., but these techniques are still implemented based on L3, and cannot fully solve the above problems. The decision to initiate WI (Work Item) standardization Work on the L1/L2 based mobility enhancement technology is made at 3gpp ran#94e, the design objective of the L1/L2 based mobility enhancement technology is to achieve a fast change of the serving cell of the UE.

There are two transmission methods in the traditional communication, one is the transmission of dynamic scheduling (dynamic scheduling), namely each transmission is based on the air interface resource allocated in real time by the network; a transmission that is not dynamically scheduled (without dynamic scheduling), i.e., the network configures the air interface resources in advance, and the UE transmits on the configured air interface resources. Not dynamic scheduling includes Semi-persistent scheduling (SPS-Persistent Scheduling) and Grant (CG), and transmissions not dynamic scheduling are applicable to periodic traffic.

Disclosure of Invention

The inventor finds through research that, for the scenario of quickly changing the serving cell of the UE, if the semi-persistent scheduling and/or configuration grant type 2 (type 2) is cleared when the UE leaves a cell, when the UE returns to the cell soon, reconfiguration activation is required, which introduces additional signaling overhead and increases the time of service interruption.

In view of the above problems, the present application discloses a solution for performing maintenance for transmissions that are not dynamically scheduled, in particular semi-persistent scheduling and configuration grant type 2, in a fast changing UE's serving cell scenario. Embodiments in a first node of the application and features in embodiments may be applied to a second node and vice versa without conflict.

Furthermore, the adoption of a unified solution for different scenarios (including but not limited to V2X scenarios and communication scenarios of terminals with base stations) also helps to reduce hardware complexity and cost.

Example 4

Embodiment 4 illustrates a hardware module diagram of a communication device according to one embodiment of the application, as shown in fig. 4. Fig. 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

The first communication device 450 includes a controller/processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter/receiver 454, and an antenna 452.

The second communication device 410 includes a controller/processor 475, a memory 476, a data source 477, a receive processor 470, a transmit processor 416, a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter/receiver 418, and an antenna 420.

In the transmission from the second communication device 410 to the first communication device 450, upper layer packets from the core network or upper layer packets from the data source 477 are provided to the controller/processor 475 at the second communication device 410. The core network and data source 477 represent all protocol layers above the L2 layer. The controller/processor 475 implements the functionality of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, a controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller/processor 475 is also responsible for retransmission of lost packets and signaling to the first 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., physical layer). Transmit processor 416 performs coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 410, as well as 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). The multi-antenna transmit processor 471 digitally space-precodes the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. A transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes with reference signals (e.g., pilots) in the time and/or frequency domain, 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 multi-carrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 to a radio frequency stream and then provides it to a different antenna 420.

In a transmission from the second communication device 410 to the first communication device 450, each receiver 454 receives a signal at the first communication device 450 through its respective antenna 452. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream that is provided to a receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions for the L1 layer. A multi-antenna receive processor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming operation from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, wherein the reference signal is to be used for channel estimation, and the data signal is subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial stream destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in a receive processor 456 and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals that were transmitted by the second communication device 410 on 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 the L2 layer. The controller/processor 459 may be associated with a memory 460 that stores program codes and data. Memory 460 may be referred to as a computer-readable medium. In the transmission from the second communication device 410 to the first communication device 450, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the second communication device 410. The upper layer packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

In the transmission from the first communication device 450 to the second communication device 410, an upper layer data packet is provided to a controller/processor 459 at the first communication device 450 using a data source 467. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit functions at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller/processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels, implementing L2 layer functions for the user and control planes. The controller/processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming, with the multi-antenna transmit processor 457 performing digital multi-antenna spatial precoding, after which the transmit processor 468 modulates the resulting spatial stream into a multi-carrier/single-carrier symbol stream, which is analog precoded/beamformed in the multi-antenna transmit processor 457 before being provided to the different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and provides it to an antenna 452.

In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals to baseband signals, and provides the baseband signals to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement the functions of the L1 layer. The controller/processor 475 implements L2 layer functions. The controller/processor 475 may be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the first communication device 450. Upper layer packets from the controller/processor 475 may be provided to all protocol layers above the core network or L2 layer, and various control signals may also be provided to the core network or L3 for L3 processing.
