Description
Technical Field
The present application relates to the field of communications, and in particular, to a resource transmission method and apparatus.
Background
The Internet of things (IoT) is a network facing Machine-to-Machine communication (MTC), and is mainly used in applications such as intelligent meter reading, medical detection and monitoring, logistics detection, industrial detection and monitoring, automobile networking, intelligent communities, and wearable devices in the future. Due to the fact that application scenes of the system are various and comprise from outdoor to indoor and from the ground to the underground, a plurality of special requirements are put on the design of the Internet of things.
Coverage enhancement: many MTC terminals are in an environment with poor coverage, such as an electric meter, a water meter, etc., and are usually installed indoors or in basements, etc., where wireless network signals are poor, and therefore a coverage enhancement technology is needed to solve the problem of communication quality under poor coverage.
A large number of low rate devices are supported: the number of MTC devices is much larger than the number of devices communicating between people, but the data packets transmitted are small and not sensitive to latency.
Very low cost: many MTC applications require very low terminal equipment costs to enable large-scale deployment.
Low energy consumption: in most cases, MTC devices are powered by batteries. At the same time, however, in many scenarios MTC is required to be able to be used for more than a decade without requiring battery replacement. This requires that MTC devices be able to operate with very low power consumption.
To meet these special requirements, the 3rd Generation Partnership Project (3 GPP), the 3rd 3GPP, has passed a new research topic at GERAN #62 times the conference to investigate methods for supporting very low complexity and low cost internet of things in cellular networks, and has established the narrowband internet of things (NB-IoT) topic at RAN #69 times the conference, and has completed both NB-IoT Rel-13 and Rel-14 versions of the standard work.
The Rel-14 does not support the reporting function of the physical layer scheduling request sr (scheduling request). For the NB-IoT terminal in the connected state and the uplink synchronization state, when uplink data arrives and there is no uplink resource, the NB-IoT terminal needs to initiate a random access process to request the uplink resource, resulting in a relatively large delay. Therefore, the need to support SR function is clearly suggested in Rel-15WID (word Item description).

Detailed Description
The technical solution in the present application will be described below with reference to the accompanying drawings.
Before the embodiments of the present application are introduced, SR in the present application is introduced:
SR (scheduling request) is used for a connected terminal, and when the terminal has uplink data to send and has no uplink resource, the terminal sends an SR to the network device to request the uplink resource to send the uplink data. The SR can be divided into a Dedicated SR and a Piggybacked SR:
1. dedicated (Dedicated) SR
The network device allocates a dedicated SR resource to the terminal, and when the terminal has uplink data to send and does not have the uplink resource, the terminal can send the SR on the allocated dedicated resource, so the SR sent on the dedicated resource is called a dedicated SR. After receiving the dedicated SR, the network device sends an uplink grant UL grant to the terminal, allocates resources, and the terminal transmits uplink data on the resources.
2. Piggybacked (Piggybacked) SR
The network device allocates a downlink Grant (DL Grant) to the terminal, and when the terminal has uplink data to send and does not have uplink resources, the terminal can send an SR on an acknowledgement/negative acknowledgement (ACK/NACK) resource, so the SR sent on the ACK/NACK resource is called a Piggybacked SR. After receiving the Piggybacked SR, the network device sends an uplink grant UL grant to the terminal, allocates resources, and the terminal transmits uplink data on the resources.
In the prior art, whether the terminal sends the SR on the ACK/NACK resource depends on whether the terminal has uplink data to send, if the terminal needs to send the uplink data, the terminal sends the SR on the ACK/NACK resource, and if the terminal does not need to send the uplink data, the terminal does not send the SR on the ACK/NACK resource, so that the terminals in a connected state are all allowed to send piggybacked SRs. For the network device, since the network device only knows that the terminal may send the SR on the ACK/NACK, but cannot know exactly whether the terminal sent the SR on the ACK/NACK, the network device needs to blindly detect whether there is the SR on the ACK/NACK resource, and the network device also needs to blindly detect whether the UE sent the ACK or NACK.

Network device 110 may be a device that communicates with a terminal device.

The method for requesting uplink transmission resources based on the SR mechanism by the terminal is described in detail below with reference to fig. 2 and 3.
Fig. 2 is a schematic flow chart of a resource transmission method provided in an embodiment of the present application. The method shown in fig. 2 comprises:
s201, the terminal sends a third message Msg3 to the network device, wherein the Msg3 carries the information for requesting transmission of SR resources.
In an embodiment of the present application, the Msg3 carries information requesting transmission of SR resources, specifically, the Msg3 may carry a bit for indicating that SR resources are requested to be transmitted, for example, when the bit is "1", it indicates that the terminal requests SR resources from the network device, and when the bit is "0", it indicates that the terminal does not request SR resources or the terminal does not support an SR mechanism.
In another embodiment of the present application, the Msg3 carries information requesting transmission of the differentiated SR resource and information requesting permission to send the Piggybacked SR, and specifically, the Msg3 may carry two bits, one bit is used to indicate whether transmission of the differentiated SR resource is requested, and the other bit is used to indicate whether transmission of the Piggybacked SR is requested, for example, when the value of the two bits is "00", the resource not requesting transmission of the differentiated SR and the resource not requesting transmission of the Piggybacked SR are indicated, "01" indicates the resource only requesting transmission of the differentiated SR, "10" indicates the resource only requesting permission of the Piggybacked SR, and "11" indicates the resource requesting transmission of the differentiated SR and the resource requesting permission to send the Piggybacked SR.
In this application, the uplink data may be status report information or alarm information of the terminal, and the third message Msg3 is a message in the connection state establishment process, and generally includes an RRCConnectionRequest, an rrcconnectionresumerrequest, an rrcconnectionrequestablistensionrequest, and the like, where the RRCConnectionRequest includes a ue-Identity, an estinewcause, and the like, and the rrcconnectionresumerrequest includes a resumeID, a resummesuse, and the like, and the bit for indicating that the SR resource is requested to be transmitted may be included in the RRCConnectionRequest, the rrcconnectionresumerrequest, or the rrcconnectionrequestablistensionrequest.
S202, the network device allocates resources for transmitting the dedicated SR according to the Msg 3.
After receiving the Msg3, if the terminal requests to transmit SR resources, the network device determines whether resources for transmitting the dedicated SR can be allocated to the terminal, and if so, the network device allocates resources for transmitting the dedicated SR to the terminal so that the terminal sends the dedicated SR; if not, for example, the resources are insufficient, the network device does not allocate the terminal with the resources for transmitting the dedicated SR, and the terminal cannot transmit the dedicated SR at this time.
S203, the network device determines whether the terminal is allowed to send the piggybacked SR.
The network device determines whether to allow the terminal to transmit the piggybacked SR, in addition to determining whether to allocate resources for transmitting the dedicated SR.
In an embodiment of the application, the Msg3 only carries information requesting transmission of the dedicated SR resource, and the network device determines whether to allow the terminal to send the piggybacked SR or not according to a detection capability, where the detection capability may be the number of the terminals that the network device has the largest blind detection, that is, whether the network device has an SR or not for blind detection of ACK/NACK sent by how many terminals, or a performance of the network device for blind detection of ACK/NACK, where the performance may be a detection omission probability or an error detection probability or other indexes.
In another embodiment of the application, the Msg3 carries information requesting transmission of a dedicated SR resource and information requesting permission to send a piggybacked SR, the network device determines whether to allow the terminal to send the piggybacked SR according to the Msg3 and the detection capability, the network device determines to allow the terminal to send the piggybacked SR only when the Msg3 carries the information requesting permission to send the piggybacked SR and the detection capability is sufficient, otherwise, the network device determines not to allow the terminal to send the piggybacked SR, for example, when the Msg3 carries information not to send the piggybacked SR or the detection capability of the network device is insufficient, the network device determines not to allow the terminal to send the piggybacked SR.
S204, the network equipment sends the resource and the indication information for transmitting the dedicated SR to the terminal.
Wherein, the indication information is used to indicate whether the terminal is allowed to send the piggybacked SR. Specifically, the indication information may be information of one bit, for example, when the bit is "1", the indication information indicates that the terminal is allowed to transmit the piggybacked SR, and when the bit is "0", the indication information indicates that the terminal is not allowed to transmit the piggybacked SR.
S205, the terminal sends the dedicated SR to the network device on the resource for transmitting the dedicated SR.
S206, the network equipment sends the downlink grant DL grant to the terminal.
The DL Grant indicates NPDSCH resources and resources of ACK/NACK.
S207, the network device sends Downlink data through a Narrowband Physical Downlink Shared Channel (NPDSCH).
Accordingly, the terminal receives downlink data on the NPDSCH resources.
S208, the terminal sends ACK/NACK to the network equipment.
The terminal transmits ACK/NACK on the ACK/NACK resource indicated by the DL Grant.
Specifically, the terminal determines whether the transmitted ACK/NACK carries the piggybacked SR or not according to the indication information, when the indication information indicates that the terminal allows the transmission of the piggybacked SR, the terminal may carry the piggybacked SR in the ACK/NACK transmitted to the network device, and when the indication information indicates that the terminal is not allowed to transmit the piggybacked SR, the terminal does not carry the piggybacked SR in the ACK/NACK transmitted to the network device.
It should be noted that, when the network device sends the indication information to the terminal, if the indication information indicates that the terminal is allowed to send piggybacked SR, the network device may perform blind detection on SR in the received ACK/NACK, where the blind detection refers to that the network device detects whether to carry SR on ACK/NACK resources and that the terminal sends ACK or NACK, and therefore, the blind detection SR generally includes 4 states: the ACK carries the SR, the NACK carries the SR, the ACK does not carry the SR, and the NACK does not carry the SR; if the indication information indicates that the terminal is not allowed to send piggybacked SR, the network equipment does not need to blindly detect SR in the received ACK/NACK.
S209, the network device sends a downlink Grant UL Grant to the terminal.
The UL Grant indicates a resource of a Narrow-band Physical Uplink Shared Channel (NPUSCH).
S210, the terminal sends uplink data to the network equipment.
And the uplink data is sent to the network equipment through the NPUSCH.
It should be noted that, in this embodiment, the execution sequence between steps S201 to S210 is not limited.
In this embodiment, the network device sends, to the terminal, indication information indicating whether to allow sending of the piggybacked SR, so that if the network device indicates that the terminal allows sending of the piggybacked SR, the network device may blindly detect the SR in ACK/NACK, and if the network device indicates that the terminal is not allowed to send the piggybacked SR, the network device may not blindly detect the SR in ACK/NACK, thereby reducing blind detection of the network device.
Fig. 3 is a schematic flowchart of a resource transmission method provided in an embodiment of the present application. In this embodiment, the terminal and the network device agree in advance, if the terminal receives the resource for transmitting the dedicated SR allocated by the network device, the terminal only sends the dedicated SR and does not send the piggybacked SR, and if the terminal does not receive the resource for transmitting the dedicated SR allocated by the network device, the terminal does not send the dedicated SR but allows sending the piggybacked SR.
Specifically, the method shown in fig. 3 includes:
s301, the terminal sends a third message Msg3 to the network device, and the Msg3 carries the information requesting to transmit the SR resources.
Specifically, when the terminal needs to send uplink data to the network device, the terminal triggers sending of a third message Msg3 to the network device, where Msg3 may carry a bit for indicating a request to transmit SR resources.
S302, the network device allocates resources for transmitting the dedicated SR according to the third message Msg 3.
In this embodiment, the network device does not send the indication information to the terminal to notify whether the terminal is allowed to send the piggybacked SR, and the network device may default that if the terminal is allocated with a resource for transmitting the dedicated SR, the terminal will not send the piggybacked SR, and if the terminal is not allocated with a resource for transmitting the dedicated SR, the terminal is allowed to send the piggybacked SR.
S303, the network device sends the resource for transmitting the dedicated SR to the terminal.
S304, the terminal sends the dedicated SR to the network equipment on the resource for transmitting the dedicated SR.
S305, the network device sends a downlink grant DL grant to the terminal.
The DL Grant indicates NPDSCH resources and resources of ACK/NACK.
S306, the network device sends downlink data through NPDSCH.
Accordingly, the terminal receives downlink data on the NPDSCH resources.
S307, the terminal sends ACK/NACK.
The terminal transmits the ACK/NACK on the ACK/NACK resource.
Since the network device sends the terminal the resource for transmitting the dedicated SR in step S303, the terminal sends ACK/NACK that does not carry piggybacked SR, that is, the terminal does not send piggybacked SR, and the network device does not blindly detect SR in the received ACK/NACK. On the contrary, if the network device does not send the resource for transmitting the dedicated SR to the terminal, the network device may blindly detect the SR in the received ACK/NACK.
And S308, the network equipment sends the downlink Grant UL Grant to the terminal.
The UL Grant indicates resources of NPUSCH.
S309, the terminal sends uplink data to the network device.
And the uplink data is sent to the network equipment through the NPUSCH.
It should be noted that, there are steps in fig. 3 and fig. 2 that describe the same, and the embodiment does not describe the same, and reference may be made to the related description in the embodiment of fig. 2; in this embodiment, the execution sequence between steps S301 to S309 is not limited.
In this embodiment, the network device does not need to send indication information to the terminal to inform whether the terminal is allowed to send the piggybacked SR, the network device defaults that if the terminal is allocated with a resource for transmitting the dedicated SR, the terminal does not send the piggybacked SR, at this time, the network device does not need to blindly detect the SR in the received ACK/NACK, if the terminal is not allocated with a resource for transmitting the dedicated SR, the terminal is allowed to send the piggybacked SR, at this time, the network device needs to blindly detect the SR in the received ACK/NACK, which reduces both the blindness of the network device and the instruction information of whether the network device is allowed to send the piggybacked SR to the terminal.
In the embodiments respectively corresponding to fig. 2 and fig. 3, when a terminal needs to send uplink data to a network device, the terminal triggers sending of a third message Msg3 to the network device to request transmission of SR resources, where Msg3 is a message in a connection state establishment process, and in the embodiment of the present application, the terminal may also request transmission of SR resources to the network device in Capability report information after the connection state establishment, for example, a request in a terminal-Capability-NB message, so that the present application provides an embodiment in which the third message Msg3 is replaced with the Capability report information in the embodiments described in fig. 2 and fig. 3, and the following briefly describes an embodiment in which the Capability report information replaces the third message Msg 3:
referring to the embodiment in fig. 2, in an embodiment of the present application, information for indicating that SR resources are requested to be transmitted is carried in capability reporting information sent by a terminal to a network device, the network device allocates resources for transmitting a differentiated SR according to the capability reporting information and determines whether the terminal is allowed to send a piggybacked SR, then the network device sends the resources for transmitting the differentiated SR and indicating information whether the terminal is allowed to send the piggybacked SR, and other steps may be described with reference to fig. 2.
Referring to the embodiment in fig. 3, in an embodiment of the present application, the capability reporting information sent by the terminal to the network device carries information for requesting transmission of SR resources, the network device allocates resources for transmitting the dedicated SR according to the capability reporting information, then the network device sends the resources for transmitting the dedicated SR to the terminal, and other steps may refer to related descriptions in fig. 3.
