Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, fig. 1 is a schematic diagram of a network structure to which the embodiment of the present invention is applicable, and as shown in fig. 1, the network structure includes a terminal 11 and a network side device 12, where the terminal 11 may be a User Equipment (UE) or other terminal devices, for example: the present invention relates to a Mobile terminal, and more particularly to a Mobile terminal, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), a robot, a vehicle, and other terminal-side devices. The network side device 12 may be a Transmission Reception Point (TRP), and the embodiment of the present invention may be applied to a multi-TRP scenario. Further, the network side device 12 may access network devices, such as base stations, for example: macro station, LTE eNB, 5G NR NB, etc.; the network side device may also be a small station, such as a Low Power Node (LPN), pico, femto, or the network side device may be an Access Point (AP); the network side device may also be a Central Unit (CU). It should be noted that, in the embodiment of the present invention, the specific type of the network-side device is not limited.
Referring to fig. 2, fig. 2 is a flowchart of a request sending method according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:
The first service bearer may be a service bearer transmitted by a required data transmission time window, for example: traffic bearers required to be transmitted within a specified time in the industrial internet may be referred to as on-time transmission (on time transmission) traffic.
The logical channel may also be a specific logical channel.
The data transmission time window required according to the service characteristic of the first service bearer may be configured in advance, or configured by a protocol agreement or a network side.
The resource allocation information is used to allocate transmission resources within a transmission time window, which is understood to mean that the transmission resources allocated by the resource allocation information belong to the transmission time window. The transmission resource may include an uplink resource, such as an uplink scheduling resource, and may also be a downlink resource.
The resource allocation information for allocating transmission resources in the transmission time window may be implemented by a terminal requesting a network side, for example: the network side performs dedicated scheduling request configuration for the logical channel, where the dedicated scheduling request configuration can request the network side device to allocate transmission resources in a transmission time window in which the terminal needs to send the logical channel service data.
Alternatively, the resource allocation information may be used to allocate transmission resources within the transmission time window by delaying allocation of transmission resources at the network side, for example: after receiving the scheduling request, the network side device delays allocation to allocate transmission resources within the transmission time window.
In the embodiment of the invention, the terminal can acquire the transmission resource in the transmission time window through the implementation, thereby meeting the requirements of the service and further improving the service transmission performance.
In addition, in the embodiment of the present invention, the method may further include:
and the terminal transmits or receives the service on the transmission resource.
As an optional implementation manner, the sending, by the terminal, the scheduling request to the network side device includes:
and the terminal triggers the scheduling request and delays sending the scheduling request.
The delay may be determined according to the time for triggering the scheduling request and the transmission time window, so as to enable the transmission resource allocated by the network side device after receiving the scheduling request to be in the transmission time window.
In this embodiment, the terminal delays sending the scheduling request to implement that the allocated transmission resource is in the transmission time window, which can reduce the complexity of the system.
Optionally, the triggering, by the terminal, the scheduling request and delaying sending the scheduling request includes:
the terminal triggers the scheduling request and delays to send the scheduling request within a preset time before the transmission time window; or
And the terminal triggers the scheduling request and delays to send the scheduling request in the transmission time window.
The preset time may be configured by the network side or agreed by a protocol, and the transmission resource allocated by the network side device after receiving the scheduling request may be in the transmission time window by the preset time.
The delaying of the transmission of the scheduling request into the transmission time window may be delaying the transmission of the scheduling request to the start of the transmission time window or a time after the start.
Further, the terminal delayed transmission scheduling request may be delayed transmission according to an instruction transmitted by the network side device. For example: the terminal triggers the scheduling request and delays to send the scheduling request within the preset time before the transmission time window, and the method comprises the following steps:
the terminal triggers the scheduling request, and transmits the scheduling request within a preset time before the transmission time window according to a first indication message transmitted by the network side equipment, wherein the first indication message is used for indicating permission of delaying transmission of the scheduling request; or
The terminal triggers the scheduling request and delays to send the scheduling request in the transmission time window, and the method comprises the following steps:
and the terminal triggers the scheduling request and delays to send the scheduling request in the transmission time window according to first indication information sent by the network side equipment, wherein the first indication information is used for indicating permission of delaying to send the scheduling request.
The first indication information may be configured when the network side device configures the scheduling request resource of the logical channel, for example: when the network side device configures the scheduling request resource for the logical channel, it indicates that the scheduling request corresponding to the scheduling request resource can be transmitted in a delayed manner (i.e., allows the delayed transmission indication). Therefore, the terminal can decide to send the scheduling request at a certain time before or in the transmission time window on the basis of the service characteristics, and the scheduling request is not sent even if scheduling request resources exist at other time points.
Optionally, the step of configuring the scheduling request resource for the logical channel to correspond to a first period and a second period, where the lengths of the first period and the second period are different, where the terminal triggers the scheduling request and delays sending the scheduling request includes:
and the terminal triggers the scheduling request and sends the scheduling request according to the first period or the second period.
The scheduling request resource may be one or more groups of scheduling request resources configured by the network side device in advance to the logical channel configuration. The sending of the scheduling request according to the first period or the second period may be determined by the terminal or determined by the terminal according to an instruction of the network side device, where the scheduling request is sent according to the first period or the second period.
In one embodiment, the configuring, by the logical channel, a set of scheduling request resources, where the set of scheduling request resources includes the first cycle and the second cycle, the first cycle is greater than the second cycle, and the first cycle corresponds to a starting cycle of the transmission time window, the transmission time window includes a plurality of the second cycles, the terminal triggers the scheduling request, and the sending the scheduling request according to the first cycle or the second cycle includes:
and the terminal triggers the scheduling request and sends the scheduling request in the period which is the closest to the triggering of the scheduling request in the first period and the second period.
In this embodiment, it can be realized that the scheduling request resource configured by the network side device for the logical channel is a group of scheduling request resources, where the scheduling request resource includes two periods, a long period and a short period, the long period corresponds to a start period of a transmission time window, and one transmission time window may include multiple short periods, so that the time distribution of the scheduling request resource can be matched with the data packet transmission window. The scheduling request resource may be configured by the network side device through RRC signaling.
In another embodiment, the configuring, by the logical channel, two groups of scheduling resources, where the two groups of scheduling resources correspond to the first cycle and the second cycle, respectively, and the triggering, by the terminal, the scheduling request, and sending the scheduling request according to the first cycle or the second cycle includes:
and the terminal triggers the scheduling request and sends the scheduling request at scheduling resources of a target period in the first period and the second period, wherein the scheduling resources of the target period are indicated by a network side.
In this embodiment, the first period and the second period may be configured in advance by the network side device, for example, configured for the logical channel in advance according to the transmission time window.
For example: the network side equipment configures two sets of scheduling request resources for one logical channel, for example, each set of scheduling request resources is configured with different cycle lengths through RRC signaling configuration, and the network side equipment sends MAC layer signaling MAC CE or physical layer signaling PDCCH to indicate which set of scheduling request resources to use, that is, specifically uses long cycle scheduling request resources or short cycle scheduling request resources.
Since the scheduled resources of the period are indicated by the network side and the transmission time window is known to the network side device, the allocated transmission resources can be within the transmission time window when one of the first period and the second period indicates to use the allocated transmission resources. And in the embodiment, the long-short period conversion can be more flexible.
As an optional implementation manner, the transmission resource of the terminal is a terminal transmission resource that is allocated in a delayed manner after the network side device receives the scheduling request.
In this embodiment, the network side device may perform dedicated scheduling request configuration for the logical channel, and after the terminal triggers and transmits the scheduling request for the logical channel, the network side device delays allocation of the transmission resource to allocate the transmission resource within the transmission time window.
In the embodiment of the invention, a terminal sends a scheduling request to network side equipment, wherein the scheduling request is related to a logic channel corresponding to a first service bearer; and the terminal receives resource allocation information sent by the network side equipment, wherein the resource allocation information is used for allocating transmission resources in a transmission time window, and the transmission time window is a data transmission time window required according to the service characteristics of the first service bearer. Therefore, the terminal can acquire the transmission resources in the transmission time window, thereby meeting the requirements of the service and further improving the service transmission performance.
Referring to fig. 3, fig. 3 is a flowchart of a resource allocation method according to an embodiment of the present invention, as shown in fig. 3, including the following steps:
Optionally, the method further includes:
and the network side equipment sends first indication information to the terminal, wherein the first indication information is used for indicating permission of delaying sending of the scheduling request.
Optionally, the scheduling request resource of the logical channel configured for the terminal by the network side device corresponds to a first period and a second period, and lengths of the first period and the second period are different.
Optionally, the scheduling request resource includes a group of scheduling request resources, where the group of scheduling request resources includes the first period and the second period, the first period is greater than the second period, the first period corresponds to a start period of the transmission time window, and the transmission time window includes a plurality of the second periods.
Optionally, the scheduling request resource includes two groups of scheduling resources, and the two groups of scheduling resources respectively correspond to the first cycle and the second cycle.
Optionally, the transmission resource of the terminal is a terminal transmission resource allocated in a delayed manner after the network side device receives the scheduling request.
It should be noted that, this embodiment is used as an implementation of the network side device corresponding to the embodiment shown in fig. 2, and specific implementation thereof may refer to the relevant description of the embodiment shown in fig. 2, so that, in order to avoid repeated description, the embodiment is not described again, and the same beneficial effects may also be achieved.
The method provided by the embodiments of the present invention is illustrated below in three embodiments:
example 1:
the embodiment is exemplified by the terminal delaying the transmission of the scheduling request
A network side: the network side device allocates a periodic dedicated SR resource (PUCCH resource) for the terminal for logical channel 1(LCH 1). And the network side equipment simultaneously indicates the SR allowed delay transmission corresponding to the logic channel in the configuration signaling.
A terminal side: as shown in fig. 4, after the packets of the LCH1 arrive at the buffer, the terminal makes a self-decision to transmit the SR only a time period before the transmission time window of the LCH1 packets or within the transmission window according to the indication that the network side device is allowed to delay transmitting the SR.
Example 2:
in this embodiment, a network side device configures two types of SR resources with long and short periods for one logical channel for example:
a network side: the method comprises the following steps that the network side equipment configures SR resources with long and short periods for a terminal, and specifically comprises the following two methods:
firstly, a network side device configures a set of SR resources (PUCCH resources) for a logical channel (LCH1) by using RRC signaling, where the SR resources include two periods, a long period and a short period, the long period corresponds to a starting period of a transmission time window, and one transmission time window may include a plurality of SR resources with short periods. Or the like, or, alternatively,
secondly, the network side equipment configures two sets of SR resource configurations (PUCCH resources) for one logic channel (LCH1) by using RRC signaling, and each set of SR resources is configured with different cycle lengths. The network side equipment sends MAC layer signaling MAC CE or physical layer signaling PDCCH to indicate which set of SR resources are used, namely, the long period SR resources or the short period SR resources are specifically used. RRC signaling may also configure which set of SR configurations to use initially, or default to use long period SR configurations in the initial state. In this way, the long and short period switching can be more flexible.
Both approaches can achieve the SR configuration effect of fig. 5.
A terminal side: the terminal acquires the SR resource configuration of the network side equipment, and the method is that the SR resource configuration is directly acquired through RRC signaling; in the second method, after acquiring the two sets of configurations through RRC signaling, it is further able to determine which set is currently activated through MAC CE or PDCCH. And after the LCH1 data packet arrives at the buffer and triggers the BSR to further trigger the SR, the SR is sent on the latest SR resource.
Example 3:
in this embodiment, the network side device may allocate transmission resources with a delay for the special SR:
a network side:
step 1: the network side device allocates a periodic dedicated SR resource (PUCCH resource) for the terminal for logical channel 1(LCH 1). Optionally, after the network side device indicates in the configuration signaling that the SR corresponding to the logical channel is received, the transmission resource may be allocated in a delayed manner.
Step 2: after receiving the SR sent in the SR resource configuration, the network side device allocates transmission resources in the LCH1 data packet transmission time window according to the transmission time window requirement of the service corresponding to the logical channel.
A terminal side: the terminal acquires the SR resource configuration of the LCH1 by the network side equipment. And after the LCH1 data packet arrives at the buffer and triggers the BSR to further trigger the SR, the SR is sent on the latest SR resource.
The embodiment of the invention can be realized as follows:
the network side equipment performs dedicated scheduling request configuration for a specific logical channel, and the dedicated scheduling request configuration can request the network side equipment to allocate transmission resources when the terminal needs to send the logical channel service data. The real-time scheduling of the network side equipment is obtained through reasonable SR transmission, and the transmission requirement of the industrial Internet for the timing transmission service is met.
Referring to fig. 6, fig. 6 is a structural diagram of a terminal according to an embodiment of the present invention, and as shown in fig. 6, a terminal 600 includes:
a sending module 601, configured to send a scheduling request to a network side device, where the scheduling request is related to a logical channel corresponding to a first service bearer;
a receiving module 602, configured to receive resource allocation information sent by the network side device, where the resource allocation information is used to allocate transmission resources in a transmission time window, and the transmission time window is a data transmission time window required according to service characteristics of the first service bearer.
Optionally, the sending module 601 is configured to trigger the scheduling request and delay sending the scheduling request.
