The low target BLER (10-5) and low latency (1 ms) requirements for URLLC traffic in 3GPP (3 rd Generation Partner Project, third Generation partnership project) new air interface Release 15 have supported Grant Free transmission, i.e., configured Grant transmission.

To support higher demand URLLC traffic, such as higher reliability (e.g., target BLER 10-6), lower latency (e.g., 0.5-1 ms), etc., the real-time and real-time enhanced SI (Study Item) of new air-interface Release16 is passed through the real-time network in 3GPP (3 rd Generation Partner Project, third generation partnership project) RAN (Radio Access Network ) #80 times. Among them, enhancement of HARQ (Hybrid Automatic Repeat reQuest ) feedback/CSI (Channel State Information, channel state information) feedback is an important point to be studied.

Disclosure of Invention

The inventors found through research that, when UCI includes HARQ/CSI and one PUCCH reserved for transmitting UCI (Uplink Control Information ) is not orthogonal to grant-free PUSCH in time domain, how to transmit UCI is a key issue to be considered in order to support higher reliability and lower delay transmission in the new air interface Release 16.

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

The application discloses a method used 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 a second radio signal and target information in the K1 sets of time-frequency resource blocks;

wherein any one of the K1 time-frequency resource block sets includes K2 time-frequency resource blocks, the K2 time-frequency resource blocks are identical at a start time of a time domain, K1 is a positive integer, and 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: for the requirements of the new air interface Release16 on higher reliability and lower time delay, how to transmit UCI when PUCCH is not orthogonal to grant-free PUSCH in the time domain.

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

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

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

According to one aspect of the present 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 time-frequency resource block set, the target time-frequency resource block set is one of the K1 time-frequency resource block sets, and the K3 is a positive integer not greater than the K2; the target time-frequency resource block set comprises M1 available REs, the target information occupies M2 available REs in the M1 available REs, the M2 available REs belong to the K3 time-frequency resource blocks, M1 is a positive integer greater than 1, and M2 is a positive integer smaller than M1; said K1 being equal to 1, a difference between said M1 and said M2 being used to determine said transport block size employed by said second wireless signal; or the K1 is greater than 1, the M1 being 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-free PUSCH is determined 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 a plurality of times and the PUCCH and one of the transmissions are not orthogonal in the time domain, UCI is mapped to the time-frequency resource of the transmission, and the same TB corresponding to the plurality of transmissions can be ensured.

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

As one embodiment, the essence of the above method is that it is determined which mapping manner of rate matching and puncturing the UCI adopts 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 a plurality of times and the PUCCH and one of the transmissions are not orthogonal in the time domain, UCI is mapped to the time-frequency resource of the transmission, and the same TB corresponding to the plurality of transmissions can be ensured.

According to one aspect of the present application, the above method is characterized in that the second radio signal includes K1 second sub-radio signals, the K1 second sub-radio signals are respectively transmitted in the K1 time-frequency resource block sets, and a second bit block is used to generate any one of the K1 second sub-radio signals; the transport block size employed by the second wireless signal is equal to the number of bits contained by the second bit block.

According to an aspect of the present application, the above method is characterized in that the target information is transmitted in the K1 sets of time-frequency resource blocks, whether or not the second radio 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 the PUCCH are not orthogonal in time domain, the base station receives UCI only in the time-frequency resource allocated only to the grant-free PUSCH among the time-frequency resource allocated to the grant-free PUSCH and the time-frequency resource allocated to the PUCCH, regardless of whether there is an uplink data transmission really on the time-frequency resource allocated to the grant-free PUSCH. The method has the advantages that if the base station blindly detects whether the PUSCH is not granted to the transmission, the misjudgment on the time-frequency resource position where UCI is transmitted is not affected, so that the transmission reliability of the UCI can be improved.

As an embodiment, the present application has the following advantages over the conventional scheme:

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

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

The method comprises the steps of determining the TB size of the grant-free PUSCH according to whether the grant-free PUSCH is transmitted once or transmitted multiple times, so that when the grant-free PUSCH is transmitted multiple times and the PUCCH and one of the transmissions are not orthogonal in time domain, UCI is mapped to time-frequency resources of the transmission, and the same TB can be ensured to be corresponding to the multiple transmissions.

And determining which mapping mode in rate matching and puncturing is adopted by the UCI according to whether the grant-free PUSCH is transmitted once or transmitted many times, so that when the grant-free PUSCH is transmitted many times and the PUCCH and one of the transmissions are not orthogonal 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.

Whenever there is no orthogonality in the grant-free PUSCH and PUCCH time domain, the base station receives UCI only in the time-frequency resource allocated only to the grant-free PUSCH among the time-frequency resource allocated to the grant-free PUSCH and the time-frequency resource allocated to PUCCH, regardless of whether there is an uplink data transmission really on the time-frequency resource allocated to the grant-free PUSCH. Therefore, even if the base station blindly detects whether the grant PUSCH is transmitted or not, the erroneous judgment on the time-frequency resource position where UCI is transmitted is not affected, and thus the transmission reliability of the UCI is improved.

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 User Equipment (UE) and a base station device (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 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 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., 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 data packets, retransmission of lost data packets, and reordering of data 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 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.
