Detailed ways

In order to facilitate the understanding of the embodiments of the present invention, the following technical points are first introduced:

When the New Radio (NR) is running on an unlicensed frequency, the transmitter (terminal or base station) should listen before talking (Listen Before Talk, LBT) before using a channel (20MHz) for transmission. The program detects the channel to determine whether the channel is available. The specific method is that the transmitter measures the power received on the channel. If the received power is higher than a preset value (the preset value is used to determine whether it is occupied), then the channel will be determined to be occupied state. On the contrary, the channel will be determined as an unoccupied state and can be used for NR signal transmission.

Currently, there are multiple types of LBT. For physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) and physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) transmission, the terminal or base station can use Type 4 (Category 4) LBT to initiate a channel occupation time (Channel Occupation) Time, COT), the base station and terminal can share this COT for data transmission. When performing Category 4 types of LBT, the transmitter (terminal or base station) can determine different priority channel access priority classes (Channel Access Priority Class, CAPC) according to different service types to determine the fallback of LBT (backoff) window length, the maximum duration of COT initiated according to different CAPC values is different; at the same time, COT initiated with a certain CAPC value x can only allow logical channels (Logical Channel, LCH) with CAPC value <= x ) Use the COT for data transmission.

If an NRU system (including one or more cells) serves both URLLC and eMBB services, the system needs to be able to schedule some resources for eMBB services while meeting the URLLC's Quality of Service (QoS) requirements. For both services, there are two scheduling methods in the uplink, one is dynamic scheduling, and the other is semi-static scheduling (configured scheduling). Dynamic scheduling means that the base station determines the type and amount of uplink data to be sent by the terminal according to the Buffer Status Report (BSR) reported by the terminal, and assigns uplink transmission permits to the terminal; semi-persistent scheduling means that the base station allocates periodic uplinks to the terminal Transmission permission. When the terminal has data transmission requirements and the data can be mapped to these uplink transmission permissions according to the mapping configuration of LCH to PUSCH, the terminal can use these uplink transmission permissions to transmit these data.

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

The embodiments of the present invention will be described below in conjunction with the drawings. The uplink transmission method and device provided in the embodiment of the present invention can be applied to a wireless communication system. Referring to FIG. 1, it is a schematic diagram of the architecture of a wireless communication system according to an embodiment of the present invention. As shown in FIG. 1, the wireless communication system may include: a network device 11 and a terminal 12. The terminal 12 may be denoted as a UE 12, and the terminal 12 may communicate with the network device 11 (transmitting signaling or transmitting data). In practical applications, the connection between the above-mentioned various devices may be a wireless connection. In order to conveniently and intuitively indicate the connection relationship between the various devices, a solid line is shown in FIG. 1.

The network device 11 provided in the embodiment of the present invention may be a base station, which may be a commonly used base station, an evolved node base station (eNB), or a network device in a 5G system (for example, the following The next generation node base station (gNB) can also be a relay device or a transmission and reception point (TRP)).

The terminal 12 provided by the embodiment of the present invention may be a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (Ultra-Mobile Personal Computer, UMPC), a netbook or a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device (MID), Wearable Device (Wearable Device), or in-vehicle equipment, etc.

Referring to FIG. 2, an embodiment of the present invention provides an uplink transmission method. The method may be executed by a terminal and includes step 201 and step 202.

Step 201: Receive load control information from the current cell or neighboring cells;

For example, when the resource or QoS of the second service cannot meet the requirements, the terminal may receive load control information of the first service from the local cell or neighboring cells. For example, when the high-priority services served by the NRU system cannot obtain sufficient resources or the QoS cannot meet the requirements, the system reduces or suspends the transmission of low-priority services through the local cell and/or broadcast signaling or group signaling. Reduce resource occupation and/or interference by low-priority services, and enhance QoS guarantee for high-priority services.

The foregoing load control information (or referred to as control signaling) refers to information used to control the load of the first service. The above-mentioned first service refers to a service that will affect other services. For example, the first service may be a low-priority service, because when low-priority services are frequently sent, it will affect the transmission of high-priority services, for example: The first service is the eMBB service. When the eMBB service is sent frequently, it will obviously increase the URLLC service sending delay or increase or decrease the sending error of the URLLC service. When the delivery of URLLC services is affected, the quality of URLLC services will be significantly reduced.

Exemplarily, in step 201, the terminal may receive the load control information from the local cell or the neighboring cell through a broadcast message, a multicast message, or a physical downlink control channel (PDCCH).

It can be understood that broadcast messages are messages broadcast by the system, such as system messages, paging messages, and so on.

The above-mentioned PDCCH may be scrambled with a pre-configured radio network temporary identifier (RNTI), for example, load control RNTI (load control RNTI).

Optionally, the broadcast message, multicast message, or PDCCH may also carry indication information, and the indication information may indicate one or more of the following:

(1) The type of the first service;

For example, the type of the first service may be eMBB.

(2) The terminal type corresponding to the first service;

(3) The group ID of the terminal group corresponding to the first service;

(4) The authorization type of the authorization corresponding to the first service;

For example, high priority or low priority grant, dynamic grant or configured grant.

(5) The unlicensed channel corresponding to the first service;

(6) Restrict the sending behavior of the first service;

For example, instructing to suspend the sending of the first service, or instructing to restart the sending of the first service.

(7) The time and frequency resources that are forbidden to be used for the first service data transmission;

(8) Limit the duration of the sending behavior of the first service data;

For example, the sending behavior of the first service data is suspended during the time period, or the sending behavior of the first service data is reduced during the time period.

(9) The terminal skips (skip) authorization (grant) type;

(10) The authorized group ID skipped by the terminal;

(11) The duration of authorization skipped by the terminal;

(12) The authorized channel skipped by the terminal;

(13) Time and frequency resources prohibited to be used by the terminal;

(14) The authorized service type skipped by the terminal;

(15) The terminal no longer skips authorization;

(16) The type of authorization that the terminal no longer skips;

(17) Lower the power threshold of Clear Channel Assessment (CCA);

(18) Increase the power threshold of CAA;

(19) Restore the power threshold of CAA.

Step 202: Adjust the uplink transmission of the first service of the local cell or the neighboring cell according to the load control information.

In the embodiment of the present invention, step 202 can be implemented in the following manner:

Manner 1: If the load control information includes the group ID of the terminal group, perform the uplink transmission of the first service on the terminal corresponding to the group ID in the local cell or the neighboring cell according to the load control information adjust;

Manner 2: If the load control information includes: the RNTI corresponding to the terminal group, adjust the uplink transmission of the first service on the terminal corresponding to the RNTI in the local cell or the neighboring cell according to the load control information ；

Manner 3: If the load control information includes: the group ID of the configured authorization group, according to the load control information, the first cell on the configured grant (configured grant) corresponding to the group ID in the local cell or neighboring cells The upstream transmission of a service is adjusted;

Manner 4: If the load control information includes the group ID of the authorized group, perform the uplink transmission of the first service on the channel corresponding to the group ID in the local cell or the neighboring cell according to the load control information Adjust, multiple grants in the grant group correspond to one channel;

Manner 5: If the load control information includes the group ID of the channel group, perform the uplink transmission of the first service on the channel corresponding to the group ID in the local cell or the neighboring cell according to the load control information adjust;

Manner 6: If the load control information includes the ID of the terminal type, adjust the uplink transmission of the first service on the terminal corresponding to the ID in the local cell or the neighboring cell according to the load control information.

In some embodiments, the adjustment includes any one of the following:

(1) Suspend the sending of the first service

For example, the first service usage configuration authorization or dynamic grant (dynamic grant) transmission is suspended.

(2) Reduce the sending of the first service;

For example, reducing the first service usage configuration authorization or dynamic authorization to send.

(3) Restart the sending of the first service;

For example, restart the first service to use configuration authorization or dynamic authorization to send.

(4) Resuming the transmission of the first service.

For example, restore the first service to use configuration authorization or dynamic authorization to send.

Taking the first service as a low-priority service as an example, methods 1 to 4 are used to introduce how the terminal adjusts the low-priority service:

Method 1: The terminal receives broadcast cell signaling or user group broadcast signaling from the base station, and according to the broadcast cell signaling or user group broadcast signaling, the terminal suspends or reduces the configured grant of low-priority services in the cell. Low priority business;

Method 2: The terminal receives broadcast cell signaling or user group broadcast signaling from the base station, and the terminal suspends or reduces the low priority services of neighboring cells according to the broadcast cell signaling or user group broadcast signaling. Use configured grant or dynamic grant to send low Priority business

Method 3: The terminal receives broadcast cell signaling or user group broadcast signaling from the base station, and the terminal restarts or restores the low-priority services of the cell according to the broadcast cell signaling or user group broadcast signaling. Use configured grant to send low-priority services ；

Method 4: The terminal receives broadcast cell signaling or user group broadcast signaling from the base station, and the terminal restarts or restores the low-priority services of neighboring cells according to the broadcast cell signaling or user group broadcast signaling. Use configured grant or dynamic grant to send low Priority business.

In some embodiments, a timer can be used to automatically restart or resume the sending of the first service.

For example, after suspending or reducing the transmission of the first service, the method shown in FIG. 2 may further include: starting or restarting an uplink data transmission prohibit timer; if the uplink data transmission prohibit timer expires, then Restart or resume sending the first service.

For example, when the terminal suspends or reduces the transmission of low-priority services, it starts or restarts an uplink data transmission prohibition timer. When the uplink data transmission prohibition timer expires, the uplink data transmission of the low-priority services affected by the message is automatically transmitted. recover.

In some implementation manners, neighboring cells may negotiate to adjust the transmission of the first service. For example, the method shown in FIG. 2 may further include: receiving first information from the own cell; wherein, the first The information indicates one or more of the following:

(1) The terminal monitors the load control information of the first service of the neighboring cell;

(2) The terminal adjusts the uplink transmission of the first service according to the load control information of the first service of the neighboring cell;

(3) The terminal reports the received load control information of the first service of the neighboring cell to the own cell.

That is, a cell can configure the terminal served by the cell to monitor the load control information of the low priority service of the neighboring cell, and/or control the low priority according to the received load control information of the low priority service of the neighboring cell Business data transmission.

Optionally, a cell may configure the terminal served by the cell to report the received load control information of the low priority service of the neighboring cell to the base station, so that the cell can adjust the scheduling in time.

In some embodiments, the method further includes: receiving configuration information (for example, resource configuration, periodic configuration, etc.) of the load control information of the first service from the neighboring cell; Load control information of the first service of the neighboring cell.

It is understandable that when this cell sends load control information for low-priority services to terminals in neighboring cells, it needs to coordinate with the neighboring cell to send the configuration information of the load control information to the neighboring cell, and then the neighboring cell will send the load control information to the neighboring cell. The configuration information is sent to the terminal it serves, and the terminal monitors the load control information from the neighboring cell according to the configuration.

For example, if the load control information sent by cell 1 to the neighboring cell (cell 2) terminal uses the PDCCH, then cell 1 should send the relevant configuration parameters of the PDCCH (for example, Control Resource Set, CORESET) configuration ( Including: resource configuration and period configuration) and downlink control information format (DCI format) used to send the PDCCH, etc. are sent to the neighboring cell, and the neighboring cell sends the PDCCH configuration to the terminal.

In the embodiment of the present invention, the terminal can receive load control information from the current cell or the neighboring cell, and then the terminal can adjust the uplink transmission of the first service of the current cell or neighboring cell according to the load control information, so that the The uplink transmission affects the uplink transmission of other services, that is, the resource occupation and/or interference of the first service can be reduced and the QoS guarantee of other services can be enhanced.

Referring to FIG. 3, an embodiment of the present invention also provides a method for uplink transmission. The execution body of the method is a network device, and the method includes: step 301.

Step 301: Send load control information to a terminal, where the load control information is used to instruct the terminal to adjust the uplink transmission of the first service.

The transmission of services, thereby reducing the resource occupation and/or interference of priority services, and enhancing the QoS guarantee of high-priority services, such as:

(1) gNB1 broadcasts cell signaling or broadcasts signaling to a user group to suspend or reduce low-priority services in the cell. Use a configured grant to send low-priority services;

(2) gNB1 broadcasts cell signaling or broadcasts signaling to a user group to suspend or reduce low-priority services of neighboring cells. Use configured grant or dynamic grant to send low-priority services;

(3) gNB1 broadcasts cell signaling or broadcasts signaling to a user group to restart or restore low-priority services in the cell. Use configured grant to send low-priority services;

(4) gNB1 broadcasts cell signaling or broadcasts signaling to a user group to restart or restore low-priority services in neighboring cells. Use configured grant or dynamic grant to send low-priority services.

Optionally, the broadcast message, multicast message or PDCCH may also carry indication information, and the indication information may be one or more of the following:

For example, the first service can be a low-priority service, because when low-priority services are frequently sent, high-priority services will be transmitted For example, the first service is the eMBB service. When the eMBB service is sent frequently, it will significantly increase the URLLC service sending delay or increase or decrease the sending error of the URLLC service. When the delivery of URLLC services is affected, the quality of URLLC services will be significantly reduced.
