Description

User equipment, method and device in base station for wireless communication

Technical Field

The present application relates to methods and apparatus in a wireless communication system, and more particularly, to methods and apparatus in a wireless communication system supporting configuration grant (configured grant) -based uplink transmission.

Background

Compared to the conventional 3GPP (3 rd Generation Partner Project, third generation partnership project) LTE (Long-term Evolution) system, the 5G system supports more diverse application scenarios, such as eMBB (enhanced Mobile BroadBand ), URLLC (Ultra-Reliable and Low Latency Communications, ultra high reliability and low latency communication) and mctc (massive Machine-Type Communications, large-scale Machine type communication). Compared with other application scenes, the URLLC has higher requirements on transmission reliability and delay. In order to reduce the additional transmission delay caused by the scheduling request and the scheduling signaling, the 3GPP R (Release) 15 supports uplink transmission based on a configuration grant (configured grant), and the UE (User Equipment) may autonomously perform uplink transmission on a pre-configured periodic resource pool. In order to ensure the reliability of transmission, the base station may further configure a repetition number to instruct the UE to repeat transmission of the same TB (Transport Block) in a period. Currently R15 defines two types of configuration grant based uplink transmissions, type 1 and Type 2.

Since the moment when a TB arrives at a UE is uncertain, when the UE first transmits one TB, the remaining time resources available for configuration grant uplink transmission in one period may not be enough to support the number of repetitions of base station configuration. If the transmission is continued until the next cycle, an additional delay is brought. To solve this problem, a plurality of resource pools for allocating grant uplink transmission may be configured on one BWP (Bandwidth Part), and different resource pools are staggered in the time domain, so that the UE may select the nearest resource pool to perform uplink transmission according to the time when the TB arrives.

Disclosure of Invention

If a UE is configured with multiple resource pools of Type 2 on a BWP for configuration grant uplink transmission and these resource pools need to be activated (activated) simultaneously, how to activate these resource pools simultaneously and minimize the required signaling overhead is a problem to be solved. In addition, different antenna ports/beams/panel/precoding matrices are used to transmit different repeated transmissions of one TB, so that the transmission reliability can be further improved by using spatial diversity gain. How to indicate the antenna ports/beams/channels/precoding matrices corresponding to multiple repeated transmissions on different resource pools with as little signaling overhead as possible is another problem to be solved.

In view of the above, the present application discloses a solution. Embodiments in the user equipment and features in the embodiments of the present application may be applied in the base station and vice versa without conflict. The embodiments of the present application and features in the embodiments may be combined with each other arbitrarily without conflict.

The application discloses a method used in user equipment for wireless communication, which is characterized by comprising the following steps:

receiving first information;

receiving a first signaling;

transmitting a first wireless signal within a first set of time-frequency resources;

wherein the first set of time-frequency resources is one of M sets of time-frequency resources; the first information and the first signaling indicate time-frequency resources occupied by a reference time-frequency resource set in the M time-frequency resource sets together, and the first information also indicates the relative relationship between the time-frequency resources occupied by each time-frequency resource set in M time-frequency resource sets except the reference time-frequency resource set and the time-frequency resources occupied by the reference time-frequency resource set in the M time-frequency resource sets; and M is a positive integer greater than 1.

As one embodiment, the problem to be solved by the present application is: one UE is configured with multiple Type 2 resource pools on one BWP for configuration grant uplink transmission, how to activate these resource pools simultaneously and minimize the required signaling overhead. The above method solves this problem by configuring the relative relationship between the multiple resource pools in the time-frequency domain with higher layer signaling.

As an embodiment, a feature of the foregoing method is that the M sets of time-frequency resources are a resource pool configured for grant of uplink transmission for a plurality of types 2 configured for one UE on one BWP, the first information is carried by higher layer signaling, and the first signaling is physical layer signaling. Because the first information indicates the relative relation between the other M-1 time-frequency resource sets and the reference time-frequency resource set on the time-frequency domain, the first signaling only needs to carry the time-frequency resource information of the reference time-frequency resource set, but does not need to carry the time-frequency resource information of the other M-1 time-frequency resource sets, so that the M time-frequency resource sets are activated simultaneously on the basis of not increasing the signaling overhead of a physical layer.

According to one aspect of the application, the first radio signal comprises K sub-signals, each of the K sub-signals carrying a first bit block, the K being a positive integer; the first set of time-frequency resources includes K first subsets of resources within which the K sub-signals are transmitted, respectively.

According to one aspect of the application, the reference time-frequency resource set includes K reference resource subsets, and K reference signals are used to determine antenna ports of wireless signals transmitted in the K reference resource subsets, respectively; the first sub-signal is any one of the K sub-signals, and a first reference signal of the K reference signals is used for determining a transmitting antenna port of the first sub-signal; the relative relationship between the time domain resources occupied by the first set of time-frequency resources and the time domain resources occupied by the reference set of time-frequency resources is used to determine the first reference signal from the K reference signals.

As an embodiment, the above method has the advantage that multiple repeated transmissions in any one of the M sets of time-frequency resources can be sent with different antenna ports/beams/panel, without increasing the signaling overhead of the physical layer.

As an embodiment, the above method is characterized in that it ensures that the receiving spatial filter of the base station for the first radio signal is independent of which one of the M sets of time-frequency resources the first set of time-frequency resources is, which benefits include reduced receiving complexity of the base station.

According to an aspect of the application, the first signaling comprises a first field, the first field in the first signaling indicating a first matrix; the reference time-frequency resource set comprises K reference resource subsets, precoding matrixes of wireless signals transmitted in the K reference resource subsets are K sub-matrixes respectively, and any one of the K sub-matrixes is composed of positive integer columns of the first matrix.

As an embodiment, the above method is characterized in that precoding vectors for different layers (layers) under high rank transmission indicated by existing DCI are used as precoding matrices for different repeated transmissions of one TB. Because the URLLC service generally adopts lower rank to ensure the transmission reliability, the method utilizes the existing DCI format to the greatest extent, reduces signaling overhead, and simultaneously realizes the use of different precoding for different repeated transmissions, thereby obtaining additional space diversity gain.

According to an aspect of the present application, the second sub-signal is any one of the K sub-signals, and the precoding matrix of the second sub-signal is a first sub-matrix of the K sub-matrices; the relative relationship between the time domain resources occupied by the first set of time-frequency resources and the time domain resources occupied by the reference set of time-frequency resources is used to determine the first sub-matrix from the K sub-matrices.

According to one aspect of the present application, it is characterized by comprising:

and determining the first time-frequency resource set from the M time-frequency resource sets by self.

According to one aspect of the present application, the method is characterized in that any one of the M sets of time-frequency resources is one of M1 sets of time-frequency resources, and M1 is a positive integer not smaller than M; the M1 time-frequency resource sets respectively correspond to M1 first class indexes; and the first type index corresponding to only the M time-frequency resource sets in the M1 time-frequency resource sets is equal to a first index, and the first signaling indicates the first index.

The application discloses a method used in a base station for wireless communication, which is characterized by comprising the following steps:

transmitting first information;

transmitting a first signaling;

receiving a first wireless signal within a first set of time-frequency resources;

and monitoring the first wireless signals in the M time-frequency resource sets respectively, and receiving the first wireless signals in the first time-frequency resource sets.

The application discloses a user equipment used for wireless communication, which is characterized by comprising:

a first receiver that receives first information;

a second receiver that receives the first signaling;

a first transmitter that transmits a first wireless signal within a first set of time-frequency resources;

The application discloses a base station used for wireless communication, which is characterized by comprising:

a second transmitter that transmits the first information;

a third transmitter that transmits the first signaling;

a third receiver that receives a first wireless signal within a first set of time-frequency resources;

As an example, compared to the conventional solution, the present application has the following advantages:

when one UE is configured with a plurality of Type 2 resource pools for configuration grant uplink transmission on one BWP, by defining a relative relationship between one of the reference resource pools and other resource pools in the time-frequency domain in advance, it is achieved that a plurality of resource pools are activated (activated) with the same physical layer signaling without increasing the physical layer signaling overhead.

Multiple repeated transmissions of one TB in any resource pool can be performed with different beams/TRP/panel, additional space diversity gain is obtained, and the signaling overhead of the physical layer is not increased.

The base station aims at configuring the receiving spatial filter which grants the uplink transmission and does not differ along with the difference of the resource pools actually used by the UE, so that the receiving complexity of the base station is reduced.

Precoding vectors for different layers (layers) under high rank transmission, indicated by existing DCI, are used as precoding matrices for different repeated transmissions. Because the URLLC service generally adopts lower rank to ensure the transmission reliability, the method utilizes the existing DCI format to the greatest extent, reduces signaling overhead, and simultaneously realizes the use of different precoding matrixes for different repeated transmissions, thereby obtaining additional space diversity gain.

Example 3

Embodiment 3 illustrates a schematic diagram of an embodiment of a radio protocol architecture for the user plane and the control plane, as shown in fig. 3.

Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane and a control plane, fig. 3 shows the radio protocol architecture for a UE and a gNB with 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. The L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY301. In the user plane, the L2 layer 305 includes a MAC (Medium Access Control ) sublayer 302, an RLC (Radio Link Control, radio link layer control protocol) sublayer 303, and a PDCP (Packet Data Convergence Protocol ) sublayer 304, which terminate at the gNB on the network side. Although not shown, the UE may have several protocol layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW213 on the network side and an application layer that terminates at the other end of the connection (e.g., remote UE, server, etc.). The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer data packets to reduce radio transmission overhead, security by ciphering the data packets, and handover support for UEs between gnbs. The RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and reordering of packets to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat reQuest ). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating the various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the UE and the gNB is substantially the same for the physical layer 301 and the L2 layer 305, but there is no header compression function for the control plane. The control plane also includes an RRC (Radio Resource Control ) sublayer 306 in layer 3 (L3 layer). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the gNB and the UE.

In DL (Downlink), at the gNB410, upper layer packets from the core network are provided to a controller/processor 475. The controller/processor 475 implements the functionality of the L2 layer. In DL, a controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocations to UE450 based on various priority metrics. The controller/processor 475 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the UE 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). The transmit processor 416 performs coding and interleaving to facilitate Forward Error Correction (FEC) at the UE450, 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 DL (Downlink), at the UE450, each receiver 454 receives signals 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, where 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 streams destined for the UE 450. The symbols on each spatial stream are demodulated and recovered in a receive processor 456 and soft decisions are generated. The soft decisions are then decoded and deinterleaved by a receive processor 456 to recover the upper layer data and control signals that were transmitted by the gNB410 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 DL, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data packets from the core network. 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. The controller/processor 459 is also responsible for error detection using Acknowledgement (ACK) and/or Negative Acknowledgement (NACK) protocols to support HARQ operations.

In UL (Uplink), a data source 467 is used at the UE450 to provide upper layer data packets to a controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function at the gNB410 described in DL, the controller/processor 459 implements header compression, ciphering, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocations of the gNB410, implementing L2 layer functions for the user and control planes. The controller/processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the gNB 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 UL (Uplink), the function at the gNB410 is similar to the reception function at the UE450 described in DL. 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 UL, the controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data packets from the UE 450. Upper layer packets from the controller/processor 475 may be provided to the core network. The controller/processor 475 is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations.
