Detailed Description
In order to facilitate understanding of the embodiments of the present invention, the following technical points are introduced:
when a New Radio (NR) operates in an unlicensed frequency, a transmitter (terminal or base station) should detect a channel according to a listen before Talk (listen before Talk, LBT) procedure before transmitting using a channel (20 MHz) to determine whether the channel is available. This is accomplished by the transmitter measuring the received power on the channel and determining that the channel is occupied if the received power is above a predetermined value (which is used to determine whether the channel is occupied). Otherwise, the channel is determined to be unoccupied and can be used for NR signaling.
Currently, there are multiple types of LBT. For Physical Uplink Shared Channel (PUSCH) and Physical Downlink Shared Channel (PDSCH) transmission, a terminal or a base station may initiate a Channel Occupancy Time (COT) using an LBT of type 4(Category 4), and the base station and the terminal may share the COT to perform data transmission. When performing a Category 4 LBT, a transmitter (terminal or base station) may determine different Priority Channel Access Priority Classes (CAPCs) according to different service types, so as to determine backoff (backoff) window lengths of the LBTs, where the maximum durations are different according to COTs initiated by different CAPC values; meanwhile, a COT initiated with a certain CAPC value x can only be allowed to be used by a Logical Channel (LCH) with a CAPC value of < ═ x 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 to the eMBB services while meeting the Quality of Service (QoS) requirements of URLLC. For two services, there are two scheduling modes in uplink, one is dynamic scheduling (dynamic scheduling) and the other is semi-static scheduling (configured scheduling). The dynamic scheduling is that the base station determines the type and the amount of uplink data to be sent of the terminal according to a Buffer Status Report (BSR) reported by the terminal, and allocates an uplink transmission permission to the terminal; semi-persistent scheduling is that a base station allocates periodic uplink transmission grants to a terminal, and when the terminal has a data transmission requirement and data can be mapped to the uplink transmission grants according to the mapping configuration from LCH to PUSCH, the terminal can transmit the data by using the uplink transmission grants.

Embodiments of the present invention are described below with reference to the accompanying drawings. The method and the equipment for uplink transmission provided by the embodiment of the invention can be applied to a wireless communication system. Referring to fig. 1, an architecture diagram of a wireless communication system according to an embodiment of the present invention is shown. As shown in fig. 1, the wireless communication system may include: network device 11 and terminal 12, terminal 12 may be referred to as UE12, and terminal 12 may communicate (transmit signaling or transmit data) with network device 11. In practical applications, the connections between the above devices may be wireless connections, and fig. 1 illustrates the connections between the devices by solid lines for convenience and convenience in visual representation.
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 (e.g., a next generation base station (gNB), or a relay device or a Transmission and Reception Point (TRP)).
The terminal 12 provided in the embodiment of the present invention may be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook or a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device.
Referring to fig. 2, an embodiment of the present invention provides a method for uplink transmission, where an execution main body of the method may be a terminal, and the method includes step 201 and step 202.
Step 201: receiving load control information from the local cell or the neighboring cell;
for example, when the resource or QoS of the second service cannot meet the requirement, the terminal may receive the load control information of the first service from the local cell or the neighboring cell. For example, when a high-priority service served by the NRU system cannot obtain sufficient resources or QoS cannot meet requirements, the system reduces or suspends transmission of a low-priority service through a local cell and/or a broadcast signaling or a mass-sending signaling, thereby reducing resource occupation and/or interference of the low-priority service and enhancing QoS guarantee of the high-priority service.
The load control information (alternatively referred to as control signaling) refers to information for controlling the load of the first traffic. The first service refers to a service that may affect other services, for example, the first service may be a low-priority service, because when the low-priority service is frequently sent, transmission of the high-priority service may be affected, for example: the first service is an eMMC service, and when the eMMC service is frequently sent, the URLLC service sending delay can be obviously increased or the URLLC service sending error can be increased or decreased. When the transmission of URLLC traffic is affected, the quality of URLLC traffic may be significantly degraded.
For example, 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 will be appreciated that the broadcast message is a message broadcast by the system, for example: system messages, paging messages, etc.
The PDCCH may be scrambled with a pre-configured Radio Network Temporary Identifier (RNTI), such as: load control rnti (load control rnti).
Optionally, the broadcast message, the multicast message, or the PDCCH may further carry indication information, where the indication information may indicate one or more of the following:
(1) a type of the first service;
for example, the type of the first service may be an eMBB.
(2) A terminal type corresponding to the first service;
(3) a group ID of a terminal group corresponding to the first service;
(4) the authorization type of the authorization corresponding to the first service;
such as a high or low priority grant, dynamic grant, or configured grant.
(5) An unauthorized channel corresponding to the first service;
(6) limiting the sending behavior of the first service;
for example, a suspension of the transmission behavior of the first traffic is indicated, or a restart of the transmission behavior of the first traffic is indicated.
(7) The first service data transmission forbids using time frequency resources;
(8) limiting the duration of the sending action of the first service data;
for example, the transmission of the first traffic data is suspended for the duration, or the transmission of the first traffic data is reduced for the duration.
(9) The terminal skips (skip) authorization (grant) types;
(10) authorized group IDs skipped by the terminal;
(11) the authorized duration skipped by the terminal;
(12) authorized channels skipped by the terminal;
(13) the terminal forbids the time frequency resource;
(14) authorized service types skipped by the terminal;
(15) the terminal no longer skips authorization;
(16) a type of authorization that the terminal no longer skips;
(17) adjusting a power threshold of Clear Channel Assessment (CCA) down;
(18) increasing the power threshold of CAA;
(19) the power threshold of CAA is restored.
Step 202: and adjusting the uplink transmission of the first service of the local cell or the adjacent cell according to the load control information.
In the embodiment of the present invention, step 202 may be implemented by:
mode 1: if the load control information includes: the group ID of the terminal group adjusts the uplink transmission of the first service on the terminal corresponding to the group ID in the local cell or the adjacent cell according to the load control information;
mode 2: if the load control information includes: the RNTI corresponding to the terminal group adjusts the uplink transmission of the first service on the terminal corresponding to the RNTI in the local cell or the adjacent cell according to the load control information;
mode 3: if the load control information includes: configuring a group ID of an authorization group, and adjusting uplink transmission of a first service on a configuration authorization (configured grant) corresponding to the group ID in the local cell or the neighboring cell according to the load control information;
mode 4: if the load control information includes: if the group ID of the authorization group is determined, adjusting uplink transmission of the first service on a channel corresponding to the group ID in the local cell or the adjacent cell according to the load control information, wherein a plurality of authorizations in the authorization group correspond to one channel;
mode 5: if the load control information includes: adjusting uplink transmission of a first service on a channel corresponding to the group ID in the local cell or the adjacent cell according to the load control information;
mode 6: if the load control information includes: and the ID of the terminal type adjusts the uplink transmission of the first service on the terminal corresponding to the ID in the local cell or the adjacent cell according to the load control information.
In some embodiments, the adjusting comprises any one of:
(1) suspending the first traffic transmission
For example, suspending the first traffic from being sent using a configuration grant or a dynamic grant (dynamic grant).
(2) Reducing the first service transmission;
for example, the first traffic is reduced from being sent using configuration grants or dynamic grants.
(3) Restarting the first service transmission;
for example, restarting the first service is sent using a configuration grant or a dynamic grant.
(4) And recovering the first service transmission.
For example, the first service is resumed using configuration authorization or dynamic authorization transmission.
In the following, taking the first service as a low priority service as an example, how the terminal adjusts the low priority service is introduced by means of the following modes 1 to 4:
mode 1: the terminal receives a broadcast cell signaling or a user group broadcast signaling from a base station, and the terminal suspends or reduces the low-priority service of the cell to use configuration authorization (configured grant) to send the low-priority service according to the broadcast cell signaling or the user group broadcast signaling;
mode 2: the terminal receives a broadcast cell signaling or a user group broadcast signaling from the base station, and the terminal suspends or reduces the low-priority service of the adjacent cell and sends the low-priority service by using a configured grant or a dynamic grant according to the broadcast cell signaling or the user group broadcast signaling;
mode 3: the terminal receives a broadcast cell signaling or a user group broadcast signaling from the base station, and restarts or recovers the low-priority service of the cell according to the broadcast cell signaling or the user group broadcast signaling and transmits the low-priority service by using a configured grant;
mode 4: the terminal receives the broadcast cell signaling or the user group broadcast signaling from the base station, and restarts or recovers the low priority service of the neighbor cell according to the broadcast cell signaling or the user group broadcast signaling and transmits the low priority service by using a configured grant or a dynamic grant.
In some embodiments, the transmission of the first traffic may be automatically restarted or resumed by a timer (timer).
For example, after suspending or reducing the first traffic transmission, the method shown in fig. 2 may further include: starting or restarting a prohibit timer (inhibit timer) for sending uplink data; and if the uplink data transmission prohibition timer is overtime, restarting or resuming to transmit the first service.
For example, after the terminal suspends or reduces the transmission of the low-priority service, an uplink data transmission prohibition timer is started or restarted, and when the uplink data transmission prohibition timer times out, the uplink data transmission of the low-priority service affected by the message is automatically resumed.
In some embodiments, the adjustment of the transmission of the first service may be negotiated between neighboring cells, for example, the method shown in fig. 2 may further include: receiving first information from the local cell; wherein the first information indicates one or more of:
(1) the terminal monitors the load control information of the first service of the adjacent cell;
(2) the terminal adjusts the uplink transmission of the first service according to the load control information of the first service of the adjacent cell;
(3) and the terminal reports the received load control information of the first service of the adjacent cell to the cell.
That is, a cell may configure a terminal served by the cell to monitor load control information of a low priority service of an adjacent cell, and/or control data transmission of the low priority service according to received load control information of the low priority service of the adjacent cell.
Optionally, a cell may configure a terminal served by the cell to report received load control information of a low priority service of an adjacent cell to the base station, so that the cell can adjust scheduling in time.
In some embodiments, the method further comprises: receiving configuration information (e.g., resource configuration, periodic configuration, etc.) of load control information of the first traffic from the neighbor cell; and monitoring the load control information of the first service from the adjacent cell according to the configuration information.
It can be understood that, when sending the load control information of the low priority service to the terminal in the neighboring cell, the cell needs to coordinate with the neighboring cell, and send the configuration information of the load control information to the neighboring cell, and then the neighboring cell sends the configuration information of the load control information to the terminal served by the neighboring cell, 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 the cell 1 to the terminal in the neighboring cell (cell 2) uses a PDCCH, the cell 1 should send the configuration parameters (e.g., Control Resource Set (core) configuration (including Resource configuration and period configuration) for sending the PDCCH, downlink Control information format (DCI format) for sending the PDCCH, and the like to the neighboring cell, and send the configuration of the PDCCH to the terminal by the neighboring cell.
In the embodiment of the present invention, the terminal may receive the load control information from the local cell or the neighboring cell, and then the terminal may adjust the uplink transmission of the first service in the local cell or the neighboring cell according to the load control information, so as to avoid an influence on the uplink transmission of other services due to the uplink transmission of the first service, that is, reduce resource occupation and/or interference of the first service, and enhance QoS guarantee of other services.
Referring to fig. 3, an embodiment of the present invention further provides an uplink transmission method, where an execution subject of the method is a network device, and the method includes: step 301.
Step 301: and sending load control information to a terminal, wherein the load control information is used for indicating the terminal to adjust the uplink sending of the first service.
For example, when a high-priority service served by an NRU system cannot obtain sufficient resources or QoS cannot meet requirements, the NRU system may send load control information to a terminal through a broadcast message, a multicast message, or a PDCCH, and reduce or suspend transmission of a low-priority service, thereby reducing resource occupation and/or interference of the priority service and enhancing QoS guarantee of the high-priority service, for example:
(1) the gNB1 broadcasts cell signaling or signaling to a user group to suspend or reduce low priority service transmission of the cell using configured grant (configured grant);
(2) the gNB1 broadcasts cell signaling or signaling to a user group to suspend or reduce low priority traffic of neighboring cells from transmitting low priority traffic using configured or dynamic traffic;
(3) the gNB1 broadcasts cell signaling or signaling to a user group to restart or recover the low priority service of the cell and uses configured grant to send the low priority service;
(4) the gNB1 broadcasts cell signaling or signaling to a user group to restart or resume low priority traffic of neighbor cells to send low priority traffic using configured or dynamic traffic.
Optionally, the broadcast message, the multicast message, or the PDCCH may further carry indication information, where the indication information may be one or more of the following:
(1) a type of the first service;
for example, the type of the first service may be an eMBB.
(2) A terminal type corresponding to the first service;
(3) a group ID of a terminal group corresponding to the first service;
(4) the authorization type of the authorization corresponding to the first service;
such as a high or low priority grant, dynamic grant, or configured grant.
(5) An unauthorized channel corresponding to the first service;
(6) limiting the sending behavior of the first service;
for example, a suspension of the transmission behavior of the first traffic is indicated, or a restart of the transmission behavior of the first traffic is indicated.
(7) The first service data transmission forbids using time frequency resources;
(8) limiting the duration of the sending action of the first service data;
for example, the transmission of the first traffic data is suspended for the duration, or the transmission of the first traffic data is reduced for the duration.
(9) The terminal skips (skip) authorization (grant) types;
(10) authorized group IDs skipped by the terminal;
(11) the authorized duration skipped by the terminal;
(12) authorized channels skipped by the terminal;
(13) the terminal forbids the time frequency resource;
(14) authorized service types skipped by the terminal;
(15) the terminal no longer skips authorization;
(16) a type of authorization that the terminal no longer skips;
(17) adjusting a power threshold of Clear Channel Assessment (CCA) down;
(18) increasing the power threshold of CAA;
(19) the power threshold of CAA is restored.
It is understood that the first service refers to a service that may affect other services, for example, the first service may be a low-priority service, because when the low-priority service is frequently sent, the transmission of the high-priority service may be affected, for example: the first service is an eMMC service, and when the eMMC service is frequently sent, the URLLC service sending delay can be obviously increased or the URLLC service sending error can be increased or decreased. When the transmission of URLLC traffic is affected, the quality of URLLC traffic may be significantly degraded.
