Description

Method and device used in user equipment and base station for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a communication method and apparatus supporting data transmission over an Unlicensed Spectrum (Unlicensed Spectrum).

Background

In the 5G system, eMBB (enhanced Mobile Broadband), and URLLC (Ultra Reliable and Low Latency Communication) are two typical traffic types. The low target BLER (10^ -5) and low latency (1ms) requirements for URLLC traffic have been supported in 3GPP (3rd Generation Partner Project) New air interface Release 15, with Grant Free (Grant Free) transmission, i.e., Configured Grant (Configured Grant) transmission.

In order to support the higher required URLLC service, such as higher reliability (e.g. target BLER of 10^ -6), lower delay (e.g. 0.5-1ms), etc., the URLLC enhanced SI (Study Item) of the new air interface Release16 is passed through at #80 omnisessions of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #80 times. Among them, the enhancement of HARQ (Hybrid Automatic repeat request) feedback/CSI (Channel State Information) feedback is a key point to be studied.

Disclosure of Invention

The inventor finds that UCI includes HARQ/CSI, and when a PUCCH reserved for sending UCI (uplink control Information) is not orthogonal to an unlicensed PUSCH in a time domain, how to send UCI is a key issue to be considered in order to support transmission with higher reliability and lower delay in new air interface Release 16.

In view of the above, the present application discloses a solution. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict.

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

-receiving first information, the first information being used for determining K1 sets of time-frequency resource blocks;

-receiving a first wireless signal;

-transmitting second wireless signals and target information in the K1 sets of time-frequency resource blocks;

any one time-frequency resource block set in the K1 time-frequency resource block sets comprises K2 time-frequency resource blocks, the K2 time-frequency resource blocks are the same at the starting time of a time domain, the K1 is a positive integer, and the K2 is a positive integer; the value of K1 is used to determine a transport block size employed by the second wireless signal; the target information is related to the first wireless signal.

As an embodiment, the problem to be solved by the present application is: aiming at the requirements of a new air interface Release16 on higher reliability and lower time delay, how to send UCI when a PUCCH is not orthogonal to a grant-free PUSCH in a time domain.

As an embodiment, the problem to be solved by the present application is: in the existing standard, when a PUCCH reserved for transmitting UCI is not orthogonal to a grant-based PUSCH in a time domain, UCI is changed to be transmitted on a grant-based PUSCH. Such as CSI feedback, is mapped to REs allocated to PUSCH in a rate-matched manner. In the grant-free PUSCH transmission, one or more transmissions of the same TB (Transport Block) may be sent in one or more consecutive slots (slots), and when the PUCCH and one of the transmissions are not orthogonal in the time domain, the PUCCH may be transmitted in the time-frequency resource occupied by the transmission instead, and if UCI is mapped to the time-frequency resource in a rate matching manner according to the prior art, the TB size in the time-frequency resource may be different from the TB size corresponding to other transmissions, which is inconsistent with the design requirement for the same TB corresponding to the multiple transmissions in the grant-free PUSCH transmission. Therefore, how UCI is mapped to resources allocated to grant-free PUSCH is a key issue that needs to be studied.

As an embodiment, the essence of the above method is that K1 sets of time-frequency resource blocks are reserved for K1 transmissions of one grant-free PUSCH, respectively, the second wireless signal is the grant-free PUSCH, and the target information is UCI related to the first wireless signal.

According to one aspect of the application, the method described above is characterized by comprising:

-receiving a first signaling;

wherein the first signaling is used to determine a first time-frequency resource, the first time-frequency resource is reserved for transmission of the target information, and time-domain resources occupied by the first time-frequency resource and time-domain resources occupied by the K1 sets of time-frequency resource blocks are overlapped.

According to an aspect of the application, the above method is characterized in that the target information is transmitted in K3 time frequency resource blocks, the K3 time frequency resource blocks belong to a target set of time frequency resource blocks, the target set of time frequency resource blocks is one of the K1 sets of time frequency resource blocks, the K3 is a positive integer not larger than the K2; the target set of time-frequency resource blocks comprises M1 available REs, the target information occupies M2 of the M1 available REs, the M2 available REs belong to the K3 time-frequency resource blocks, the M1 is a positive integer greater than 1, and the M2 is a positive integer smaller than the M1; the K1 is equal to 1, the difference of the M1 and the M2 is used to determine the transport block size employed by the second wireless signal; or the K1 is greater than 1, the M1 is used to determine the transport block size employed by the second wireless signal.

As one embodiment, the essence of the above method is that the TB size of the grant-less PUSCH is determined according to whether the grant-less PUSCH is transmitted once or multiple times. The method has the advantages that when the grant-free PUSCH is transmitted for multiple times and the PUCCH is not orthogonal to one transmission in the time domain, the UCI is mapped to the time-frequency resource of the transmission, and the same TB corresponding to the multiple transmissions can be ensured.

According to one aspect of the present application, the above method is characterized in that the K1 is equal to 1, and the target information is mapped onto the M2 available REs by means of rate matching; or the K1 is greater than 1, and the target information is mapped onto the M2 available REs in a puncturing manner.

As an embodiment, the essence of the above method is that it is determined which mapping scheme of rate matching and puncturing is used by UCI according to whether the grant-free PUSCH is transmitted once or multiple times. The method has the advantages that when the grant-free PUSCH is transmitted for multiple times and the PUCCH is not orthogonal to one transmission in the time domain, the UCI is mapped to the time-frequency resource of the transmission, and the same TB corresponding to the multiple transmissions can be ensured.

According to an aspect of the application, the above method is characterized in that the second wireless signals comprise K1 second sub wireless signals, the K1 second sub wireless signals are respectively transmitted in the K1 sets of time-frequency resource blocks, a second bit block is used for generating any one of the K1 second sub wireless signals; the transport block size used by the second wireless signal is equal to the number of bits contained in the second bit block.

According to an aspect of the present application, the method is characterized in that the ue determines by itself whether to transmit the second wireless signal in the K1 sets of time-frequency resource blocks.

According to an aspect of the application, the above method is characterized in that the target information is transmitted in the K1 sets of time-frequency resource blocks, irrespective of whether the second wireless signal is transmitted in the K1 sets of time-frequency resource blocks.

As an embodiment, the essence of the above method is that, whenever the grant-free PUSCH and PUCCH are not orthogonal in time domain, regardless of whether there is actually uplink data transmission on the time-frequency resource allocated to the grant-free PUSCH, the base station receives UCI only in the time-frequency resource allocated to the grant-free PUSCH and only the time-frequency resource allocated to the grant-free PUSCH among the time-frequency resources allocated to the grant-free PUSCH and the time-frequency resources allocated to the PUCCH. The method has the advantages that if the base station blindly detects whether the granted PUSCH is transmitted or not, the misjudgment of the time-frequency resource position where the UCI is transmitted is not influenced, so that the transmission reliability of the UCI can be improved.

aiming at the requirements of new air interface Release16 on higher reliability and lower time delay, when PUCCH is not orthogonal to grant-free PUSCH in time domain, the method and the device solve the problem of how to send UCI.

In the grant-free PUSCH transmission, one or more transmissions of the same TB (Transport Block) may be sent in one or more consecutive slots (slots), and when the PUCCH and one of the transmissions are not orthogonal in the time domain, the PUCCH may be transmitted in the time-frequency resource occupied by the transmission instead, and if the UCI is mapped to the time-frequency resource in a rate matching manner according to the prior art, the size of the TB in the time-frequency resource may be different from the size of the TBs corresponding to other transmissions, which is inconsistent with the design requirement for the same TB corresponding to the multiple transmissions in the grant-free PUSCH transmission. The method and the device solve the problem of how UCI is mapped to the resource allocated to the grant-free PUSCH.

Whenever the grant-free PUSCH and PUCCH are not orthogonal in time domain, regardless of whether there is actually uplink data transmission on the time-frequency resource allocated to the grant-free PUSCH, the base station receives UCI only in the time-frequency resource allocated to the grant-free PUSCH and only the time-frequency resource allocated to the grant-free PUSCH among the time-frequency resources allocated to the grant-free PUSCH and the time-frequency resources allocated to the PUCCH. Therefore, even if the base station blindly detects whether the granted PUSCH is transmitted or not and has misjudgment, the misjudgment on the time-frequency resource position where the UCI is transmitted is not influenced, and the transmission reliability of the UCI is improved.

Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for the user plane and the control plane according to the present application, as shown in fig. 3.

Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for the User Equipment (UE) and the base station equipment (gNB or eNB) in 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 PHY 301. Layer 2(L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY 301. In the user plane, the L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio link 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 upper layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., far end 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. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating 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 without the header compression function for the control plane. The Control plane also includes an RRC (Radio Resource Control) sublayer 306 in layer 3 (layer L3). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configures the lower layers using RRC signaling between the gNB and the UE.
