For a commercial mobile communication system, an operator needs to auction authorized spectrum, and after obtaining authorization, the operator can use the corresponding spectrum to conduct mobile communication operation. Unlicensed spectrum does not require auctions and anyone can legally use these bands. In the 3GPP RAN #75 meeting, the "enhancements to LTE operation occupied spectrum" was successful, wherein the main research content includes specific support for multiple starting and ending locations in a subframe for UL and DL on cell with Frame structure type3, i.e. research is performed on the starting and ending locations of the uplink and downlink of authorized-assisted access (LAA). In 190 conferences of the RAN, the following policy is reached regarding automatic uplink transmission: the support of automotius uplink access with frame structure type3is specified with The scope of Release 15FeLAA WI.: the study starts with subframe type3 automatic uplink transmission at rel.15.

Detailed Description

The technical solution in the embodiments of the present invention will be described below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention.

Fig. 1 is a schematic diagram of a communication system architecture according to an embodiment of the present invention. The system comprises: a terminal and a base station. The terminal can establish a communication connection with the base station.

A Base Station (BS) is a device deployed in a radio access network to provide a wireless communication function for a communication node. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different radio access technologies, the names of devices with base station functions may be different, for example, in an LTE network, the device is called an evolved node B (eNB or eNodeB), in a third generation 3G network, the device is called a node B (node B), and so on. For convenience of description, the above-mentioned apparatuses for providing a terminal with a wireless communication function are collectively referred to as a base station or BS in this application.

The terminal in the embodiments of the present application includes but is not limited to: a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like.

The following describes in detail a processing procedure of the method for allocating resources according to the embodiment of the present invention with reference to fig. 2 and 9.

Fig. 2 is a flowchart of a method for allocating resources according to an embodiment of the present invention. As shown in fig. 2, the resource allocation method may include the steps of:

step S201: the base station sends a first message to the terminal, wherein the first message is used for indicating the terminal to perform AUL offset, and the value of the offset is greater than or equal to 1 Orthogonal Frequency Division Multiplexing (OFDM) symbol and less than or equal to 5 OFDM symbols.

In one possible embodiment, the method for the base station to send the first message may include, but is not limited to: the base station transmits the first message through a Radio Resource Control (RRC) message, Downlink Control Information (DCI), or a broadcast message.

Step S202: the terminal receives a first message sent by the base station.

Step S203: and the terminal determines the position for carrying out automatic uplink transmission (AUL) according to the initial position and the offset of the SUL.

In one possible embodiment, the first message may include one or more offsets.

Specifically, when the first message includes an offset, the terminal determines the position for performing the automatic uplink transmission AUL according to the offset and the start position of the SUL. Or, when the first message includes multiple offsets, the terminal selects one offset from the multiple offsets, and determines the position for performing the automatic uplink transmission AUL according to the offset and the start position of the SUL. The manner of selecting one offset from the multiple offsets may be random selection, or selection according to a rule, which is not described herein.

The plurality of offsets may be the same or different.

It is assumed that uplink transmission employs a Time Division Multiplexing (TDM) pattern, where the multiple offsets are different or the same.

Specifically, different UEs occupy resources of different time periods, and the starting position of the SUL uplink transmission is fixed, for example, the symbol 0 starts. In order to avoid resource collision between the AUL and the SUL and guarantee transmission of the SUL data, the UE1 and the UE2 Listen Before Talk (LBT) first, and after transmitting the guaranteed SUL data, the UE1 and the UE2 autonomously transmit the AUL, wherein the AUL may randomly select some offset values on the basis of the start position of transmission of the SUL data, the offset values are greater than or equal to 1 OFDM symbol and less than or equal to 5 OFDM symbols, and backoff during the offset, so as to avoid collision with the SUL transmission.

It should be noted that, a subframe has a time length of 1ms, and includes 2 slots, and 7 OFDM symbols in one slot, and then there are 14 OFDM symbols in one subframe, in the embodiment of the present invention, the start position of the SUL may be symbol 0, or may be symbol 7, and in order to avoid the position where the AUL transmits data, the value of the offset cannot be less than or equal to 0OFDM symbol, or cannot be greater than 6OFDM symbols. The offset value may be greater than 1 OFDM symbol and less than or equal to 5 OFDM symbols.

In some embodiments, when the UE needs to transmit data over the unlicensed spectrum, the UE first detects a channel. As shown in fig. 3, when the UE1 and the UE2 transmit data on the unlicensed spectrum and detect that the channel is busy (channel busy), backoff is required, and the channel is accessed after the backoff is finished, and the starting position of uplink transmission of the SUL is fixed, so that when the UE1 and the UE2 perform AUL transmission, the starting transmission position of the AUL is determined by adding an offset value to the starting position of the SUL, and data is transmitted from the position, so that collision with the SUL transmission can be avoided.

It is assumed that the uplink transmission employs a Frequency Division Multiplexing (FDM) mode, where the multiple offsets are the same.

Specifically, as shown in fig. 4, by adopting an interleaving (interleaving) structure in the frequency domain, different UEs may occupy one or more interleaving, such as UE1 and UE2 in fig. 4, and since the time-frequency resources are all pre-configured to the AUL resource and multiple AUL UEs transmit on the resource at the same time, in order to avoid collision with the SUL resource, and ensure that the AULUE may transmit at the same time, the same offset value is configured to different AUL UEs.

In one possible embodiment, the base station may configure the plurality of offsets in the following several ways.

In TDM mode, the base station may configure a set of offset values semi-statically through higher layer signaling, such as RRC signaling, and when the UE performs AUL transmission, the base station may randomly select from the set of offset values, so as to avoid collision with the UE transmitting the SUL. A set of offset values may be set within a threshold range within which an offset value from a set of offset values may be selected to transmit the AUL. The semi-static state refers to a configuration of a set of offset values by the base station in a certain period, and the set of offset values is constant in the period.

In the FDM mode, the base station may notify the UE through a higher layer signaling or a broadcast signaling, or may notify the UE in a common search space (common search space) of DCI, so that all AUL UEs may use the same offset value to avoid collision with the UE transmitting SUL.

Offset can be represented by a few bits, e.g., 2 bits, with the 2bit information as shown in the following table:

index	Offset value
		00	Offset 0
01	Offset 1
		10	Offset 2
11	Offset 3

in the above table, the position of transmitting the AUL is determined according to the offset value; for example, when the offset value is 0, it is determined that the AUL is transmitted at the 00 position.

The embodiment of the invention provides a resource allocation method, which determines the initial position of AUL through the offset included in a first message sent by a base station and the initial position of SUL, thereby effectively avoiding collision between SUL and AUL resources and improving the utilization rate of a channel.

The method described in the above embodiment enables the terminal to determine the starting position for performing the AUL. Accordingly, an embodiment of the present invention provides a terminal, configured to implement the method for allocating resources provided in the foregoing embodiment, as shown in fig. 5, the terminal may include: a receiving unit 510, a processing unit 520 and a transmitting unit 530.

In an alternative embodiment, the receiving unit 510 in the aforementioned embodiment illustrated in fig. 5 may be implemented by the receiver 610. Specifically, the first message is information received by the receiver 610 from the base station. Specifically, the first message is used to instruct the terminal to perform an offset of the automatic uplink transmission AUL, where the offset value is greater than or equal to 1 OFDM symbol and less than or equal to 5 OFDM symbols.

The processing procedure related to each unit in fig. 8 can refer to the embodiment shown in fig. 2, and is not described herein again.

Fig. 9 is a flowchart of another method for allocating resources according to an embodiment of the present invention. As shown in fig. 9, the resource allocation method may include the steps of:

step S901: and the base station sends the second indication information to the terminal.

In one possible embodiment, the method for the base station to send the second message may include, but is not limited to: the base station transmits the second message through a Radio Resource Control (RRC) message, Downlink Control Information (DCI), or a broadcast message.

Step S902: and the terminal receives a second message sent by the base station, wherein the second message is used for indicating whether the base station schedules SUL transmission on the preconfigured AUL resource or not, so that the terminal determines whether AUL transmission is carried out on the preconfigured AUL resource or not according to the second message.

Step S903: and the terminal determines whether to perform AUL transmission on the pre-configured AUL resource according to the second message.

In one possible embodiment, if the second message indicates that the base station does not schedule the SUL transmission on the preconfigured AUL resource, the terminal performs the AUL transmission on the preconfigured resource.

In one possible embodiment, if the second message instructs the base station to schedule the SUL transmission on the preconfigured AUL resource, the terminal cancels the AUL transmission on the preconfigured resource.

Specifically, before sending uplink data on the preconfigured AUL resource, the AUL UE detects a common search space, and if an indication related to an uplink data duration (UL burst duration) is detected in the common search space (the indication information is used for indicating a length of a time-frequency resource for transmitting LAA SUL), and the SUL time-frequency resource overlaps with a time-frequency resource (overlap) of the preconfigured AUL, the AUL UE determines a related subframe time-frequency resource for transmitting SUL uplink data according to the related indication of the UL burst duration, and abandons the AUL transmission on the related subframe time-frequency resource, thereby avoiding collision with the SUL resource and ensuring sending of SUL data.

In one possible embodiment, several bits of information may be added to the common search space of the PDCCH to inform the UE whether the base station schedules the SUL to transmit on the time-frequency resource of the AUL. For example, the base station adds 1-bit information to the common search space of the PDCCH to notify the UE whether the base station schedules the SUL to transmit on the time-frequency resource of the AUL, where the 1-bit information may be inside or outside bytes of the common search space.

Specifically, when the base station schedules the SUL to transmit on the AUL resource, the base station notifies the AUL UE through dynamic signaling, and does not transmit AUL data in the corresponding overlap resource range; if the 1bit information is 0, the base station does not schedule the SUL resource to be sent on the AUL time frequency resource, and the AUL UE can normally send AUL data at the moment; and if the 1bit information takes 1, the base station schedules the SUL resource to be sent on the AUL time frequency resource, and at the moment, the AUL UE determines the time frequency resource of the overlapped sub-frame according to the information such as UL burst and the like, cancels the AUL data transmission on the time frequency resource of the corresponding sub-frame, avoids the collision of the sending resource and ensures the normal transmission of the SUL.
