Description

BSR reporting method and mobile terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a Buffer Status Report (BSR) reporting method and a mobile terminal.

Background

At present, when a mobile terminal has uplink data to send, the mobile terminal first sends a Scheduling Request (RS) to a network side device on a specified uplink resource, the network side device allocates an uplink grant (UL grant) to the mobile terminal after receiving an SR sent by the mobile terminal, and then the mobile terminal sends a BSR to the network side device on the uplink grant, and after receiving the BSR sent by the mobile terminal, the network side device obtains a data volume of an uplink service that the mobile terminal needs to send according to the BSR, and performs data Scheduling according to the data volume and a priority of the uplink service.

According to the reporting trigger mode of the BSR, the BSR comprises: three of regular BSR (regular BSR), periodic BSR (periodic BSR), and padding BSR (padding BSR), and in practice, multiple reporting triggering manners are often satisfied simultaneously, thereby triggering two or more of regular BSR, periodic BSR, and padding BSR. In addition, the BSRs reported by the regular BSR, the periodic BSR and the padding BSR may be short BSR (short BSR) or long BSR (long BSR), and in a New Radio (NR) system, the accuracy of reporting the resource information required by the mobile terminal, which can be provided to the network side device, is different, so in this case, how to improve the accuracy of providing the resource information required by the mobile terminal to the network side device is an urgent problem to be solved.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. 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 application.

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone.

The terms "first" and "second," and the like, in the description and in the claims of the present application, are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first and second half presentation operations, etc. are for distinguishing between different presentation operations, rather than for describing a particular order of presentation operations.

In the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion. Further, in the description of the embodiments of the present application, the meaning of "a plurality" means two or more unless otherwise specified.

In a Long Term Evolution (LTE) system, multiple reporting triggering modes are often satisfied at the same time, so as to trigger reporting of two or more of a regular BSR, a periodic BSR, and a padding BSR, but if multiple BSRs with the same content are reported at the same time, unnecessary signaling overhead is brought, and therefore, the LTE system provides: a Media Access Control (MAC) Protocol Data Unit (PDU) can only contain a MAC Control Element (CE) of one BSR at most, and regular BSRs and periodic BSRs are transmitted prior to padding BSRs. In the NR system, when only one LCG has data to upload, the regular BSR and the periodic BSR report short BSRs, and the padding BSR reports either a long BSR or a short BSR according to the difference of the padding bit number. In addition, in the NR system, the accuracy of the resource information required by the mobile terminal that the long BSR can provide to the network side device is higher than the accuracy of the resource information required by the mobile terminal that the short BSR can provide to the network side device. If corresponding BSR transmission is still performed in the NR system according to the provisions in the LTE system, when only one LCG has data to upload and multiple BSRs are triggered, the mobile terminal may preferentially transmit a regular BSR and/or a short BSR reported by a periodic BSR to the network side device. Therefore, the BSR of the resource information required by the mobile terminal with lower accuracy is sent to the network side device, which is obviously not beneficial to providing the network side with the resource information required by the mobile terminal with higher accuracy, so how to improve the accuracy of providing the network side device with the resource information required by the mobile terminal is an urgent problem to be solved.

In order to solve the problem, embodiments of the present application provide a BSR reporting method and a mobile terminal. The BSR reporting method comprises the steps that under the condition that the mobile terminal is determined to have only one LCG to be uploaded with data, and the first triggering condition of a first reporting mode is met, and the second triggering condition of a second reporting mode is met, the mobile terminal reports a second BSR to network side equipment; that is, when only one LCG has data to be uploaded and meets both a first trigger condition for reporting the first BSR and a second trigger condition for reporting the second BSR, the second BSR is sent; since the number of bits occupied by the buffer domain of the first BSR is less than the number of bits occupied by the buffer domain of the second BSR, the accuracy of the resource information required by the mobile terminal, which can be provided by the first BSR to the network side device, is lower than the accuracy of the resource information required by the mobile terminal, which can be provided by the second BSR to the network side device, and therefore, in the embodiment of the present application, the accuracy of the resource information required by the mobile terminal, which is provided by the network side device, can be improved by sending the second BSR under the condition that the first trigger condition for reporting the first BSR and the second trigger condition for reporting the second BSR are simultaneously satisfied.

As shown in fig. 1, in an application scenario of the embodiment of the present application, a system architecture applied by the BSR reporting method according to the embodiment of the present application may include: a mobile terminal 10 and a base station 20. The mobile terminal 10 is connected to the base station 20 through a wireless communication link established with the base station 20.

Among other things, the mobile terminal 10 may also be referred to as a terminal (terminal), a mobile station (mobile station), a subscriber unit (subscriber unit), a station (station), etc. The mobile terminal may be specifically a cellular phone (cellular phone), a Personal Digital Assistant (PDA), a wireless modem (modem), a wireless communication device, a handheld device (hand-held), a laptop computer (laptop computer), a cordless phone (cordless phone), a Wireless Local Loop (WLL) station, and the like. When the mobile terminal is applied to M2M mode communication, the mobile terminal may also be referred to as an M2M terminal, and specifically may be a smart meter, a smart appliance, or the like, which supports M2M communication. The mobile terminal may also be a tablet, a smart car, a sensing device, an Internet Of Things (IOT) device, a Customer Premises Equipment (CPE), a relay base station, a relay terminal, and a computer having a mobile terminal, and may also be a portable, pocket, hand-held, computer-embedded, or vehicle-mounted mobile device that exchanges language and/or data with a radio access network. Such as a cellular phone, a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, and a Wireless Local Loop (WLL) station. A wireless terminal may also be referred to as a User Agent (User Agent), User Equipment (User Device), or User Equipment (UE). As an example, in the embodiment of the present application, fig. 1 illustrates that the mobile terminal 10 is a mobile phone.

The base station 20 may be specifically any one or more combinations of a gNB, a New radio base station (New radio eNB), a Transmission and Reception Point (TRP), a macro base station, a micro base station, a high frequency base station, an LTE macro or micro eNB, a CPE, a WLAN Access Point (AP), a WLAN Group Owner (GO), and the like.

The first embodiment,

Embodiments of the present invention provide a BSR reporting method, where an execution subject of each step of the method may be any one of the above mobile terminals. Referring to FIG. 2, the method may include the following steps S11-S12.

And S11, determining that only one LCG of the mobile terminal has data to be uploaded, and the LCG meets the first trigger condition of the first reporting mode and the second trigger condition of the second reporting mode.

The BSR reported by the first reporting mode is a first BSR, and the BSR reported by the second reporting mode is a second BSR; the number of bits occupied by the Buffer Size of the first BSR is less than the number of bits occupied by the Buffer Size of the second BSR.

Specifically, the BSR is information informing a network side device that the mobile terminal needs to send the data volume of the uplink service, and in order to reduce signaling overhead generated by reporting the BSR, a plurality of logical channels are put into an LCG, and the BSR is reported based on the LCG. Illustratively, every fourth logical channel may be placed in one LCG.

Optionally, the first triggering condition is a triggering condition for triggering a regular BSR, and the first BSR is a BSR reported by the regular BSR.

Among them, since the NR system specifies: when only one LCG has data to upload, the short BSR is reported by the regular BSR, so when the embodiment of the present application is applied to an NR system and the first triggering condition is a triggering condition for triggering the regular BSR, the first BSR in the embodiment of the present application is the short BSR in the NR system.

Specifically, the format of the short BSR in the NR system may be as shown in fig. 3, where the short BSR in the NR system occupies 8 bits in total, and includes: 1 identification field (LCG ID)31 and 1 Buffer field (Buffer Size) 32. The identification domain 31 occupies 3 bits (bit7, bit6 and bit5) and carries the identification information of the corresponding LCG; the buffer domain 32 occupies 5 bits (bit4, bit3, bit2, bit1, bit0) and carries information for identifying the data size to be uploaded by the corresponding LCG. For example: if the LCG corresponding to a short BSR in the NR system is LCG1, the identifier domain of the short BSR carries identifier information of LCG1, and the cache domain of the short BSR is used to carry information identifying the data size that LCG1 needs to upload.

Further, the triggering condition for triggering the regular BSR in the above embodiment may specifically include one or more of the following triggering conditions:

1. data is required to be uploaded on one logical channel belonging to one LCG, and the priority of the logical channel having the data to be uploaded is higher than that of any current logical channel.

2. Data is required to be uploaded on one logic channel belonging to one LCG, and no data is required to be uploaded on other logic channels in the LCG.

3. The BSR retransmission Timer (retxsbsr-Timer) times out.

Optionally, the first triggering condition is a triggering condition for triggering a periodic BSR, and the first BSR is a BSR reported by the periodic BSR.

Among them, since the NR system specifies: when only one LCG has data to upload, the short BSR is reported by the periodic BSR, and thus when the embodiment of the present application is applied to an NR system and the first triggering condition is a triggering condition for triggering the periodic BSR, the first BSR in the embodiment of the present application is the short BSR in the NR system.

Further, the triggering condition for triggering the periodic BSR in the above embodiment may specifically include: the periodic BSR Timer (periodic BSR-Timer) times out.

Optionally, the first triggering condition is a triggering condition for triggering a regular BSR and a triggering condition for triggering a periodic BSR, and the first BSR is a BSR reported by the regular BSR and a BSR reported by the periodic BSR.

The triggering conditions for triggering the regular BSR and the triggering conditions for triggering the periodic BSR may be the same as those in the above embodiments, and are not described herein again.

Since the first BSR in the embodiment of the present application may be a short BSR in an NR system, optionally, the first BSR in the embodiment of the present application includes:

1 identification domain and 1 cache domain;

the identification domain occupies 3 bits and is used for bearing the identification information of the LCG;

the cache domain occupies 5 bits and is used for bearing information for identifying the data volume needing to be uploaded by the LCG.

Optionally, the second triggering condition is that the number of filling bits of the first uplink resource is greater than or equal to the sum of the number of bits occupied by the second BSR and the number of bits occupied by the MAC subhead of the second BSR; the first uplink resource is an uplink resource which is allocated to the mobile terminal by the network side equipment and is used for reporting a BSR (buffer status report); the second BSR is a BSR reported by the padding BSR.

Optionally, the first UPLink resource may specifically be an UPLink grant (UPLink grant, UL grant) allocated by the network side device to the mobile terminal.

Specifically, the trigger condition for padding BSR may be: the network side equipment allocates uplink authorization for the mobile terminal, and the number of filling bits of the uplink authorization is greater than or equal to the sum of the number of bits occupied by the BSR and the number of bits occupied by the MAC subheader of the BSR. Reporting the short BSR if the filling bit number authorized by the uplink is less than the sum of the bit number occupied by the long BSR and the bit number occupied by the MAC subhead of the second BSR; reporting the long BSR if the padding bit number of the uplink grant is greater than or equal to the sum of the bit number occupied by the long BSR and the bit number occupied by the MAC subhead of the second BSR, so that when the embodiment of the present application is applied to an NR system and the padding bit number of the uplink resource allocated by the network side device for the mobile terminal to report the BSR is greater than or equal to the sum of the bit number occupied by the long BSR and the bit number occupied by the MAC subhead of the second BSR, the second BSR in the embodiment of the present application is a short BSR in the NR system.

Specifically, the format of the long BSR in the NR system may be as shown in fig. 4, where the long BSR in the NR system occupies 8 × m +1 bits, which includes: an identification field (LCG ID)41 and m Buffer fields (Buffer Size)42, m being the number of LCGs that have data to upload. The identification domain 41 occupies 8 bits, and each of the 8 bits carries 1 piece of identification information of the LCG, which has data to be uploaded; each of the m buffer areas 42 occupies 8 bits and carries information for identifying 1 LCG having data to be uploaded, which needs to upload. For example: if 3 LCGs of LCG0, LCG1, and LCG2 have data to upload, the long BSR occupies 8 bits (3+1) to 32 bits. The identification field 41 occupies 8 bits, and 3 bits of the 8 bits respectively carry identification information of the LCG0, the LCG1, and the LCG 2; each of the 3 buffer areas 42 occupies 8 bits, and occupies 24 bits, and the 3 buffer areas respectively carry information of data amount that needs to be uploaded by the

LCGs

0, 1, and 2.

Because only one logical channel group LCG has data to upload in the technical solution provided in the present application, when the second BSR in the present application is a long BSR in an NR system, the second BSR includes: 1 identification domain and 1 cache domain;

the identification domain occupies 8 bits and is used for bearing the identification information of the LCG;

the cache domain occupies 8 bits and carries information for identifying the data volume which needs to be uploaded by the LCG.

And S12, the mobile terminal reports the second BSR to the network side equipment.

Specifically, when the first BSR is the BSR reported by the regular BSR and/or the periodic BSR, and the second BSR is the BSR reported by the padding BSR, the priority of the regular BSR, the periodic BSR, and the padding BSR may be set so that when only one LCG of the logical channel group of the mobile terminal needs to upload data, the priority of the padding BSR is greater than the priority of the regular BSR and the periodic BSR, so that the mobile terminal reports the second BSR corresponding to the padding BSR to the network side device. That is, when the mobile terminal has only one logical channel group LCG to upload data, the padding BSR is sent prior to the regular BSR and the periodic BSR.

Optionally, the second BSR includes: MAC CE;

in step S12, the reporting, by the mobile terminal, the second BSR to the network side device may specifically be:

and the mobile terminal reports the MAC CE of the second BSR to the network side equipment.

That is, the mobile terminal reports the second BSR to the network-side device by reporting the MAC CE of the second BSR to the network-side device.

Further, on the basis of the above embodiment, the BSR reporting method provided by the present application further includes:

and the mobile terminal reports the first BSR to the network side equipment.

That is, the mobile terminal reports the second BSR to the network side device and reports the first BSR to the network side device.

Optionally, the first BSR includes: MAC CE;

in the above method, the reporting, by the mobile terminal, the first BSR to the network side device may specifically be:

and the mobile terminal reports the MAC CE of the first BSR to the network side equipment.

That is, the mobile terminal reports the first BSR to the network-side device by reporting the MAC CE of the first BSR to the network-side device.

Specifically, when the mobile terminal reports the first BSR to the network-side device by reporting the MAC CE of the first BSR to the network-side device, it is possible to allow one MAC PDU to include two or more BSR MAC CEs when the mobile terminal has only one LCG of a logical channel group and needs to upload data, so that the mobile terminal not only reports the second BSR to the network-side device, but also reports the first BSR to the network-side device.

The mobile terminal reports the second BSR to the network side equipment and reports the first BSR to the network side equipment, so that the accuracy of resource information required by the mobile terminal and provided for the network side equipment can be improved, and the triggered BSR does not need to be selected when the BSR is reported, so that the information processing amount of the mobile terminal can be further reduced, and the performance of the mobile terminal is improved.

A first sending unit 52, configured to report the second BSR to a network side device.

Optionally, referring to fig. 6, the mobile terminal provided in the embodiment of the present invention further includes:

the second sending unit 53 is further configured to report the first BSR to the network side device.

Optionally, the second BSR includes: a media access control unit, MAC CE;

the first sending unit 52 is specifically configured to report the MAC CE of the second BSR to the network side device.

Optionally, the first BSR includes: a media access control unit, MAC CE;

Optionally, the first trigger condition is a trigger condition for triggering a regular BSR, and the first BSR is a BSR reported by the regular BSR;

or;

the first trigger condition is a trigger condition for triggering a periodic BSR, and the first BSR is a BSR reported by the periodic BSR;

or;

Optionally, the first BSR includes: 1 identification domain and 1 cache domain;

Optionally, the second BSR includes: 1 identification domain and 1 cache domain;

In the mobile terminal provided by the embodiment of the application, when the processing unit determines that only one LCG has data to be uploaded, and the processing unit meets both a first trigger condition of a first reporting mode and a second trigger condition of a second reporting mode, the first sending unit reports a second BSR to the network side device; that is, when only one LCG has data to be uploaded and meets both a first trigger condition for reporting the first BSR and a second trigger condition for reporting the second BSR, the second BSR is sent; since the number of bits occupied by the buffer domain of the first BSR is less than the number of bits occupied by the buffer domain of the second BSR, the accuracy of the resource information required by the mobile terminal, which can be provided by the first BSR to the network side device, is lower than the accuracy of the resource information required by the mobile terminal, which can be provided by the second BSR to the network side device, and therefore, in the embodiment of the present application, the accuracy of the resource information required by the mobile terminal, which is provided by the network side device, can be improved by sending the second BSR under the condition that the first trigger condition for reporting the first BSR and the second trigger condition for reporting the second BSR are simultaneously satisfied.

a radio frequency unit 101, configured to report the second BSR to a network side device; wherein the number of bits occupied by the Buffer Size of the first BSR is less than the number of bits occupied by the Buffer Size of the second BSR.

Since the number of bits occupied by the buffer domain of the first BSR is less than the number of bits occupied by the buffer domain of the second BSR, the accuracy of the resource information required by the mobile terminal, which can be provided by the first BSR to the network side device, is lower than the accuracy of the resource information required by the mobile terminal, which can be provided by the first BSR to the network side device, and therefore, in the embodiment of the present application, the accuracy of the resource information required by the mobile terminal, which is provided by the network side device, can be improved by sending the second BSR under the condition that the triggering condition for reporting the first BSR and the triggering condition for reporting the second BSR are simultaneously satisfied.

The image frames processed by the graphic processor 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the radio frequency unit 101 or the network module 102. The microphone 1042 may receive sound and may be capable of processing such sound into audio data. The processed audio data may be converted into a format output transmittable to a mobile communication base station via the radio frequency unit 101 in case of a phone call mode.
