Description

Technical Field
The present invention relates to the field of communications technologies, and in particular, to a transmission method, a terminal device, and a network side device.
Background
After a UE (User Equipment) triggers a BSR (Buffer Status Report) Report, if no uplink resource can transmit the BSR, the UE triggers an SR (Scheduling Request) to transmit.
After the UE triggers SR transmission, the UE performs LBT (Listen Before Talk) to detect whether the frequency for SR transmission is idle, and if the frequency is already occupied, the actual transmission of the SR may fail. Since the UE starts an SR Prohibit Timer (i.e., SR-Prohibit Timer) after triggering SR transmission, an SR transmission failure (actually not transmitted) caused by the LBT may cause an SR not to be immediately transmitted in the subsequent available SR resources, resulting in an extra SR transmission delay.
In the prior art, no effective solution is provided at present for the problem of SR transmission delay caused by LBT failure of the terminal device.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be implemented, for example, in a sequence other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in the specification and claims means that at least one of the connected objects, such as a and/or B and/or C, means that 7 cases are included that include a alone, B alone, C alone, and both a and B, B and C, a and C, and A, B and C.
For ease of understanding, some terms referred to in the embodiments of the present invention are described below:
LBT (Listen-Before-Talk, say Listen Before):
for an unlicensed frequency band, a transmitting end needs to monitor whether the frequency band is occupied before transmitting a signal, and if the frequency band is not occupied, the transmitting end can transmit the signal in the frequency band.
SR (Scheduling Request) trigger:
after a UE (User Equipment) (also referred to as a terminal device) triggers a BSR (buffer status report) report, if no uplink resource can send the BSR, the UE triggers an SR (Scheduling Request) to send, where SR resources used for sending the SR may be configured on one or more cells.
When a MAC (Medium Access Control) layer of the UE indicates a PHY (physical) layer to transmit an SR on a certain SR resource, the UE may start an SR Prohibit Timer (i.e., SR-Prohibit Timer), and may add 1 to an SR transmission number COUNTER (i.e., SR _ COUNTER).
The UE cannot send an SR on this SR resource until the SR Prohibit Timer (i.e., SR-Prohibit Timer) times out.
When the number of SR transmission times COUNTER (i.e., SR _ COUNTER) reaches the threshold value (i.e., SR _ COUNTER > ═ SR-TransMax), the UE considers that the SR procedure has failed and initiates a random access procedure.
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 Device 11 and a network-side Device 12, where the terminal Device 11 may be a terminal-side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that a specific type of the terminal Device 11 is not limited in the embodiment of the present invention. The network side device 12 may be a base station, for example: macro station, LTE eNB, 5G NR NB, gNB, etc.; the network side device 12 may also be a small station, such as a Low Power Node (LPN) pico, femto, or the network side device 12 may be an Access Point (AP); the base station may also be a network node formed by a Central Unit (CU) and a plurality of Transmission Reception Points (TRPs) whose management is controlled. It should be noted that the specific type of the network-side device 12 is not limited in the embodiment of the present invention.
In this embodiment of the present invention, after triggering SR transmission, the terminal device 11 may monitor N SR resources indicated by the SR resource configuration information, and transmit an SR by using an SR resource in a transmittable state among the N SR resources, where N is an integer greater than 1.
The SR resource configuration information may be predefined by a protocol, or may be configured by the network side device 12. The SR resource configuration information may include SR resource location information, where the SR resource location information may include at least one of frequency domain information, time domain information, and spatial domain information.
It is to be understood that the SR resource location information may include a plurality of frequency domain information, a plurality of time domain information, or a plurality of spatial domain information. For example, the frequency domain information may include a frequency point identifier a1, a frequency point identifier a2, and a frequency point identifier a 3.
Optionally, the SR resource configuration information may further include quantity information of SR resources, where the quantity information of SR resources may include at least one of a quantity of SR resources corresponding to a frequency domain, a quantity of SR resources corresponding to a time domain, and a quantity of SR resources corresponding to a space domain.
In the embodiment of the invention, the terminal equipment can be indicated with a plurality of SR resources by configuring the position information of the starting SR resource and the quantity information of the SR resources. For example, the location information of the initial SR resource is frequency point 1, the number information of the SR resources is 3, and 3 SR resources that are continuous from frequency point 1 may be used for SR transmission by the terminal device; the location information SSB _1 of the starting SR resource, the number information of the SR resource being 4, may be that 4 SR resources indicated by 4 consecutive spatial domain numbers (i.e., SSB _1 to SSB _4) from the SSB _1 are used for SR transmission by the terminal device. The embodiment of the invention can indicate a plurality of SR resources to the terminal equipment by configuring the position information of the initial SR resource and the quantity information of the SR resources, thereby reducing the size of the SR resource configuration information and saving the system resources.
For example, referring to fig. 2, four SR resources, SR #1 to SR #4 shown in fig. 2, may be indicated to the terminal device based on the frequency point identifier f1, the start time position t0 of SR transmission, the transmission period △ t of SR, and the number 4 of SR resources.
The SR resource in a transmittable state of the N SR resources may refer to an SR resource not occupied by other transmission devices of the N SR resources or an SR resource in an idle state. Specifically, the terminal device 11 may monitor the N SR resources respectively after triggering SR transmission, and may transmit an SR by using the SR resources when it is monitored that a certain SR resource is in a transmittable state.
Optionally, after the SR is successfully transmitted, the terminal device 11 may indicate that the transmission is successful. For example, the PHY layer of the terminal device successfully transmits the SR on a certain SR resource, the PHY layer may indicate that the SR transmission by the MAC layer was successful.
Optionally, after the SR transmission fails, that is, there is no SR resource in a transmittable state in the N SR resources, at this time, the terminal device 11 may indicate that the transmission fails. For example, if the PHY layer of the terminal device 11 fails to successfully transmit the SR on the N SR resources indicated by the MAC layer, the PHY layer may indicate that the MAC layer has failed to transmit the SR.
In the embodiment of the present invention, after the terminal device 11 triggers SR transmission, it may respectively monitor whether N SR resources are in a transmittable state, and may transmit an SR by using an SR resource in a transmittable state among the N SR resources, so that a probability of SR transmission success may be improved, and a probability of SR transmission delay may be further reduced. In addition, in the prior art, after SR transmission is triggered, the terminal device counts the SR transmission counter, so that SR transmission failure caused by LBT can cause SR transmission frequency to be continuously counted, and SR process failure is more easily caused.
The embodiment of the invention provides a transmission method which is applied to terminal equipment. Referring to fig. 3, fig. 3 is a flowchart of a transmission method according to an embodiment of the present invention, as shown in fig. 3, including the following steps:
step 301, transmitting an SR by using a target scheduling request SR resource; the target SR resource is an SR resource in a transmittable state among N SR resources, where the N SR resources are SR resources indicated by the SR resource configuration information, and N is an integer greater than 1.
In this embodiment of the present invention, the SR resource in a transmittable state (i.e., the target SR resource) may refer to an SR resource that is not occupied by other transmission devices or an SR resource that is idle. Specifically, after triggering SR transmission, the terminal device may monitor N SR resources indicated by the SR resource configuration information, and may transmit an SR using a certain SR resource when it is monitored that the SR resource is in a transmittable state.
For example, when the MAC layer of the terminal device triggers SR transmission, N SR resources indicated by the SR resource configuration information are indicated to the PHY layer, and the PHY layer monitors the N SR resources respectively, and if there is an SR resource that can transmit an SR (e.g., frequency point 1 is not occupied), the PHY layer transmits an SR on the SR resource. It can be understood that, for other SR resources (that is, all SR resources except the SR resource that transmits the SR among the N SR resources) indicated by the MAC layer this time, the PHY layer may not transmit the SR any more, and may also continue to transmit the SR, which is not limited in this embodiment of the present invention.
According to the transmission method provided by the embodiment of the invention, the terminal equipment can monitor a plurality of SR resources to send the SR, so that the success probability of SR sending can be improved, and the probability of SR sending delay can be further reduced.
Optionally, the SR resource configuration information may be configured by a network side or predefined by a protocol.
Optionally, the SR resource configuration information may include SR resource location information, and the SR resource location information may include at least one of frequency domain information, time domain information, and spatial domain information.
In practical applications, the RS resources corresponding to different frequency domain information, time domain information, or spatial domain information are different. Accordingly, the SR resource location information may include at least one of different frequency domain information, different time domain information, and different spatial domain information.
For example, referring to fig. 2, SR #1 to SR #8 respectively represent eight different SR resources, wherein SR #1 to SR #4 and SR #5 to SR #8 have the same frequency and different time, and the four pairs of SR resources, SR #1 and SR #5, SR #2 and SR #6, SR #3 and SR #7, and SR #4 and SR #8, have the same time and different frequency.
Optionally, the frequency domain information may include at least one of: cell identification, cell group identification, frequency point identification, bandwidth identification and bandwidth part BWP identification.
In the embodiment of the present invention, the Cell identifier is used to indicate a Cell, for example, Serving Cell _ 1. The above Cell Group identifier is used to indicate a Cell Group, e.g., MCG (Master Cell Group). The frequency point identifier is used for indicating a frequency point, for example, 3.5 GHz. The bandwidth indicator is used to indicate the bandwidth, for example, 20 MHz. The BWP (bandwidth part) flag is used to indicate a bandwidth part, for example, BWP _ 1.
Optionally, the time domain information includes at least one of: the time interval of the SR transmission, the period of the SR transmission and the starting time position of the SR transmission.
In the embodiment of the invention, the time region of the SR transmission, the period of the SR transmission and the initial time position of the SR transmission can be reasonably set according to actual conditions. For example, the time zone for SR transmission may be a time interval of 10ms from the SR trigger time; the SR transmission period may be once every 2ms within a 10ms transmission time interval; the start time position of the above SR transmission may be a timing indicated by a Slot (i.e., Slot) number 1.
Optionally, the spatial domain information includes at least one of: and the reference signal identifier corresponding to the SR resource and the beam identifier corresponding to the SR resource.
In this embodiment of the present invention, the reference Signal identifier corresponding to the SR resource is used to indicate a reference Signal, and may include an SSB (Synchronous Signal Block) identifier, for example, SSB _ 1; a CSI-RS (Channel State Information Reference Signal) identification may also be included.
Optionally, the reference signal identifier corresponding to the SR resource may include at least one of a synchronization signal block SSB identifier and a channel state information reference signal CSI-RS identifier.
The Beam identifier corresponding to the SR resource is used to indicate a Beam, e.g., Beam _ 1.
It should be noted that the frequency domain information, the time domain information, the spatial domain information, and the like may be arbitrarily combined according to actual requirements, and this is not limited in the embodiment of the present invention.
Optionally, the SR resource configuration information may further include quantity information of SR resources, where the quantity information of SR resources includes at least one of:
the number of SR resources corresponding to the frequency domain;
the number of SR resources corresponding to the time domain;
the number of SR resources corresponding to the spatial domain.
In this embodiment of the present invention, the number of SR resources corresponding to the frequency domain may refer to the number of SR resources indicated by different frequency domain information, for example, 3 SR resources that are continuous from the frequency point 1. The number of SR resources corresponding to the time domain may refer to the number of SR resources indicated by different time domain information, for example, 4 SR resources that are consecutive in time from the trigger time of the SR. The number of SR resources corresponding to the spatial domain may refer to the number of SR resources indicated by different spatial domain information, for example, 4 SR resources indicated by 4 consecutive spatial domain numbers (e.g., SSB _1 to SSB _4) starting from SSB _ 1.
In an embodiment, a plurality of frequency domain information, a plurality of time domain information, or a plurality of spatial domain information, etc. may be directly configured to directly indicate a plurality of SR resources. For example, a plurality of frequency point identifiers, such as frequency point identifier a1, frequency point identifier a2 and frequency point identifier a3, may be configured directly.
In another embodiment, a plurality of SR resources may be indicated to the terminal device by configuring location information of the starting SR resource and quantity information of the SR resources. For example, the location information of the initial SR resource is frequency point 1, the number information of the SR resources is 3, and 3 SR resources that are continuous from frequency point 1 may be used for SR transmission by the terminal device; the location information SSB _1 of the starting SR resource, the number information of the SR resource is 4, and 4 SR resources indicated by 4 consecutive spatial domain numbers from SSB _1 may be used for SR transmission by the terminal device. The embodiment of the invention can only configure the position information of the initial SR resource and the quantity information of the SR resources, namely can indicate a plurality of SR resources to the terminal equipment, can reduce the size of the configuration information and save the system resources.
Optionally, when the terminal device successfully sends the SR, the SR is indicated to be successfully sent.
In this embodiment of the present invention, the successful SR transmission by the terminal device may mean that at least one SR resource exists in the N SR resources and is in a transmittable state, and the SR is successfully transmitted by using a certain SR resource in the transmittable state.
For example, if the PHY layer of the terminal device successfully transmits an SR on one of the SR resources indicated by the MAC layer, the PHY layer may transmit an SR transmission success indication to the MAC layer.
Optionally, the method further includes:
and indicating that the SR transmission fails under the condition that the terminal equipment fails to transmit the SR.
In this embodiment of the present invention, the failure of the terminal device to send the SR may be that none of the N SR resources successfully sends the SR, for example, all of the N SR resources are occupied.
For example, if the PHY layer of the terminal device fails to successfully transmit the SR on the N SR resources indicated by the MAC layer, the PHY layer may transmit an SR transmission failure indication to the MAC layer. The MAC layer may stop the SR prohibit timer after receiving the SR transmission failure indication, and may add 1 to the value of the SR transmission failure counter.
Optionally, the method further includes:
starting an SR prohibit timer after transmitting an SR by using the target SR resource;
and in the running process of the SR prohibiting timer, prohibiting a physical PHY layer of the terminal equipment from sending the SR.
In the embodiment of the present invention, after the SR resource (i.e., the target SR resource) in the transmittable state among the N SR resources is successfully used to transmit the SR, the SR prohibit timer may be started, and the physical PHY layer of the terminal device is prohibited from transmitting the SR when the SR prohibit timer is not timed out.
For example, the MAC layer of the terminal device indicates 5 SR resources in the time domain to the PHY layer, and the PHY layer of the terminal device successfully sends an SR in the 1 st SR resource, the terminal device starts the SR prohibit timer, so that the PHY layer of the terminal device does not send an SR any more for the remaining 4 SR resources, thereby avoiding repeated sending of SRs and saving system resources.
Optionally, during the operation of the SR prohibition timer, the MAC layer of the terminal device may also be prohibited from triggering SR transmission, that is, the MAC layer of the terminal device cannot instruct the PHY layer to transmit an SR.
Optionally, in the embodiment of the present invention, the SR prohibition timer may also be started when the end device triggers the SR to send. For example, in the case where the MAC layer of the terminal device instructs the PHY layer to transmit the SR, the SR prohibition timer is started.
That is, the start condition of the SR prohibit timer may further include at least one of: the terminal equipment sends the SR; the terminal device triggers the transmission of the SR.
Optionally, the stop condition of the SR prohibit timer may include: SR transmission of the terminal device fails. For example, in the case where the MAC layer of the terminal device receives an SR transmission failure indication transmitted by the PHY layer, the SR prohibit timer may be stopped.
Optionally, after the SR is transmitted by using the target SR resource, the method further includes:
adding 1 to the value of the SR sending time counter; or
The value of the SR transmission number counter is incremented by N.
In an embodiment, the value of the SR transmission number COUNTER (i.e., SR _ COUNTER) may be incremented by 1 after each SR transmission is triggered, regardless of the number of indicated SR resources. For example, the MAC layer indicates SR resources of 5 time domains of the PHY layer, and the MAC layer increments an SR transmission COUNTER value by 1, that is, SR _ COUNTER + 1.
In another embodiment, the value of the SR transmission number COUNTER (i.e., SR _ COUNTER) may be incremented by N after each SR transmission is triggered, where N is the indicated number of SR resources. For example, the MAC layer indicates SR resources of 5 time domains of the PHY layer, and the MAC layer increments the SR transmission COUNTER value by 5, that is, SR _ COUNTER + 5.
In another embodiment, the value of the SR transmission counter may be increased only in case of a successful SR transmission, that is, in case of a failed SR transmission, the value of the SR transmission counter of the terminal device is not increased. For example, the MAC layer indicates 5 SR resources of the PHY layer in time domain to transmit an SR, but the value of the SR transmission counter of the MAC layer is not increased if the PHY layer fails to transmit an SR in the 5 SR resources.
It can be understood that, in the embodiment of the present invention, the value of the SR transmission counter may be increased only in case that the SR transmission is successful; it is also possible to increase the value of the SR transmission counter after the SR transmission is triggered, and in case it is determined that the SR transmission fails, to subtract the previously increased value accordingly, for example, to increase the SR transmission counter by 1 after the SR transmission is triggered, and to decrease the SR transmission counter by 1 in case it is determined that the SR transmission fails.
Optionally, the terminal device may trigger the random access procedure when the value of the SR transmission counter reaches the transmission number threshold (i.e., SR-TransMax).
Optionally, in the embodiment of the present invention, an SR transmission FAILURE COUNTER (i.e., SR _ FAILURE _ COUNTER) may be further set for the SR process, where the SR transmission FAILURE COUNTER performs count accumulation for each SR transmission FAILURE. For example, when the initial value of SR _ FAILURE _ COUNTER is 0, and the MAC layer instructs the PHY layer to transmit an SR on SR resources of 5 time domains, but the PHY layer does not transmit successfully, the PHY layer instructs the MAC layer to transmit an SR FAILURE, and at this time, SR _ FAILURE _ COUNTER is SR _ FAILURE _ COUNTER + 1.
Optionally, when the value of the SR transmission failure counter reaches the threshold value of the transmission failure, the terminal device may add 1 to the value of the SR transmission number counter, or determine that the SR process fails.
It should be noted that, the processing behavior of the terminal device when the SR process is determined to fail may be the processing behavior of the terminal device when the value of the SR transmission number counter reaches the transmission number threshold value, for example, the random access process is triggered.
The embodiment of the invention also provides a transmission method which is applied to the network side equipment. Referring to fig. 4, fig. 4 is a flowchart of another transmission method provided in the embodiment of the present invention, and as shown in fig. 4, the method includes the following steps:

In the embodiment of the present invention, the N SR resources are used for the terminal device to send an SR to the network side device, that is, when the terminal device triggers SR sending, whether the N SR resources are in a transmittable state may be monitored, and the SR resources in the transmittable state may be used to send an SR.
Specifically, SR resource configuration information for indicating N SR resources is sent to the terminal device by the network side device, so that flexibility of SR resource configuration can be improved. Accordingly, the terminal device may perform SR transmission based on the N SR resources indicated by the SR resource configuration information sent by the network side device, which may improve the probability of SR transmission success, and may further reduce the probability of SR transmission delay.
Optionally, the SR resource configuration information includes SR resource location information, and the SR resource location information includes at least one of frequency domain information, time domain information, and spatial domain information.

The number of SR resources corresponding to the time domain may refer to the number of SR resources indicated by different time domain information, for example, 4 SR resources that are consecutive in time from the trigger time of the SR. The number of SR resources corresponding to the spatial domain may refer to the number of SR resources indicated by different spatial domain information, for example, 4 SR resources indicated by 4 consecutive spatial domain numbers (e.g., SSB _1 to SSB _4) starting from SSB _ 1.
In an embodiment, a plurality of frequency domain information, a plurality of time domain information, or a plurality of spatial domain information, etc. may be directly configured to directly indicate a plurality of SR resources. For example, a plurality of frequency point identifiers, such as frequency point identifier a1, frequency point identifier a2 and frequency point identifier a3, may be configured directly.
In another embodiment, a plurality of SR resources may be indicated to the terminal device by configuring location information of the starting SR resource and quantity information of the SR resources. For example, the location information of the initial SR resource is frequency point 1, the number information of the SR resources is 3, and 3 SR resources that are continuous from frequency point 1 may be used for SR transmission by the terminal device; the location information SSB _1 of the starting SR resource, the number information of the SR resource is 4, and 4 SR resources indicated by 4 consecutive spatial domain numbers from SSB _1 may be used for SR transmission by the terminal device. The embodiment of the invention can only configure the position information of the initial SR resource and the quantity information of the SR resources, namely can indicate a plurality of SR resources to the terminal equipment, can reduce the size of the configuration information and save the system resources.
Referring to fig. 5, a transmission method provided in an embodiment of the present invention includes the following steps:
step 501, network side configuration or protocol agreement is used for SR resource configuration information sent by SR.
The SR resource configuration information may include a plurality of SR resource location information.
Wherein the SR resource location information may include at least one of:
frequency domain information corresponding to the SR resource, that is, the frequency domain information;
time domain information corresponding to the SR resource, that is, the time domain information;
the spatial domain information corresponding to the SR resource, that is, the spatial domain information described above.
Wherein, the frequency domain information corresponding to the SR resource may include at least one of:
cell identification, e.g., Serving Cell _ 1;
cell group identification, e.g., MCG;
frequency point identification, e.g., 3.5 GHz;
bandwidth identification, e.g., 20 MHz;
BWP identifies, for example, BWP _ 1.
Wherein, the time domain information corresponding to the SR resource may include at least one of:
a time interval of SR transmission, for example, a time interval of 10ms from the SR departure time;
the SR transmission period, for example, 1 SR transmission resource every 2ms in a 10ms transmission time interval;

Wherein, the spatial domain information corresponding to the SR resource may include at least one of:
reference signal identification corresponding to the SR resource, e.g., SSB _ 1;
the Beam corresponding to the SR resource identifies, for example, Beam _ 1.
Wherein the reference signal identifier corresponding to the SR resource may include at least one of:
SSB identification;
and CSI-RS identification.
Optionally, the SR resource configuration information may further include quantity information of the SR resource, where the quantity information of the SR resource may include at least one of the following items:
the number of SR resources corresponding to the frequency domain, for example, 3 SR resources that are continuous from the frequency point 1;
the number of SR resources corresponding to a time domain, for example, 4 SR resources that are consecutive in time from the trigger time of the SR;
the number of SR resources corresponding to the spatial domain, for example, 4 SR resources indicated by 4 consecutive spatial domain numbers (e.g., SSB _1 to SSB _4) starting from number 1 (e.g., SSB _ 1).
Step 502, when triggering SR transmission, the UE monitors whether a plurality of SR resources indicated by the SR resource configuration information are in an idle state, and if there is a target SR resource in the idle state, the UE transmits an SR using the target SR resource.
For example, when the MAC layer of the UE triggers SR transmission, the MAC layer indicates a plurality of SR resources indicated by the SR resource configuration information to the PHY layer, and the PHY layer monitors the plurality of SR resources, and if there is an SR resource that can transmit an SR (e.g., frequency point 1 is not occupied), the PHY layer transmits an SR on the SR resource, and for other SR resources indicated by the MAC layer this time, the PHY layer does not transmit an SR any more.
In step 503, the UE generates an SR transmission success indication when the SR transmission is successful.
For example, if the PHY layer of the UE successfully transmits an SR on one of the SR resources indicated by the MAC layer, the PHY layer may transmit an SR transmission success indication to the MAC layer.
Step 504, the UE generates an SR transmission failure indication when the SR transmission fails.
For example, if the PHY layer of the UE fails to successfully transmit the SR on 1 or more SR resources indicated by the MAC layer, the PHY layer indicates the MAC layer to transmit the SR failure indication.
Optionally, the UE includes at least one of the following for SR prohibit sending timer processing of the SR procedure:
in the operation process of the SR prohibit timer, the MAC layer of the UE cannot trigger the SR transmission, that is, the MAC layer of the UE cannot instruct the PHY layer to transmit the SR;
during the SR prohibit timer operation, the PHY layer of the UE cannot transmit the SR.
For example, the MAC layer of the UE (i.e., the terminal device) indicates 5 SR resources in the time domain to the PHY layer, and the PHY layer of the UE successfully sends an SR in the 1 st SR resource, the UE starts the SR prohibit timer, so that the PHY layer of the UE does not send an SR any more for the remaining 4 SR resources, thereby avoiding repeated sending of SRs and saving system resources.
Wherein, the starting condition of the SR prohibit transmission timer may include any one of the following:
the UE transmits the SR, e.g., the PHY layer of the UE transmits the SR;
the UE triggers the transmission of the SR, e.g., the MAC layer of the UE indicates to the PHY layer to transmit the SR.
The stop condition of the SR prohibit transmission timer may include:
the SR transmission of the UE fails, for example, the MAC layer of the UE receives an SR transmission failure indication transmitted by the PHY layer.
Optionally, the UE may process the SR transmission counter of the SR procedure by at least one of:
for a plurality of SR transmission resources triggered 1 time, the value of the SR transmission number counter is incremented by 1. For example, the MAC layer indicates SR resources of 5 time domains of the PHY layer, and the MAC layer increments an SR transmission COUNTER value by 1, that is, SR _ COUNTER + 1.
For a plurality of SR sending resources triggered at 1 time, the UE accumulates the SR sending counter according to the number of the SR resources. For example, the MAC layer indicates SR resources of 5 time domains of the PHY layer, and the MAC layer increments the SR transmission COUNTER value by 5, that is, SR _ COUNTER + 5.
For the case where SR transmission is unsuccessful, the SR transmission counter of the UE is not incremented. For example, the MAC layer indicates 5 SR resources of the PHY layer in time domain to transmit an SR, but the value of the SR transmission counter of the MAC layer is not increased if the PHY layer fails to transmit an SR in the 5 SR resources.
Optionally, the terminal device may trigger the random access procedure when the value of the SR transmission counter reaches the transmission number threshold (i.e., SR-TransMax).
Optionally, in the embodiment of the present invention, an SR transmission FAILURE COUNTER (i.e., SR _ FAILURE _ COUNTER) may be further set for the SR process, where the SR transmission FAILURE COUNTER performs count accumulation for each SR transmission FAILURE. For example, when the initial value of SR _ FAILURE _ COUNTER is 0, and the MAC layer instructs the PHY layer to transmit an SR on SR resources of 5 time domains, but the PHY layer does not transmit successfully, the PHY layer instructs the MAC layer to transmit an SR FAILURE, and at this time, SR _ FAILURE _ COUNTER is SR _ FAILURE _ COUNTER + 1.
Optionally, when the value of the SR transmission failure counter reaches the threshold value of transmission failure, the processing behavior of the UE may include any one of the following:
adding 1 to the value of the SR sending time counter;
and determining that the SR process fails, wherein the processing behavior when determining that the SR process fails may be the processing behavior when the value of the SR transmission number counter reaches the transmission number threshold value, for example, triggering the random access process.
In the embodiment of the present invention, for each SR transmission, the UE may continuously monitor multiple SR resources (e.g., different times, different frequencies, and/or different beams), and if it is monitored that a certain SR resource can transmit an SR (e.g., can transmit after LBT detection), the UE may transmit an SR using the SR resource, so as to reduce the probability of SR process failure.
