Description

Communication method and device

Technical Field

Embodiments of the present application relate to the field of communications technologies, and in particular, to a communication method and apparatus.

Background

When a terminal sends a Buffer Status Reporting (BSR) to a base station, the BSR carries a data volume of data to be transmitted, so that the base station performs resource allocation according to the data volume of the data to be transmitted.

The BSR generally includes a Buffer Size (BS) field and an identification of a Logical Channel Group (LCG) _i ) Field, LCG _i The field is used for indicating the relevant information of the LCG, and the BS field is used for indicating the data volume of the data to be transmitted. Specifically, the BS field includes an index (index) for indicating an indirect indication of the data amount of the data to be transmitted, and the BS indicates a range of the data amount of the data to be transmitted. And, when the BS field is larger, the more corresponding BSs are, the more finely the range of the reported data amount of the data to be transmitted is divided. Therefore, after receiving the BSR, the base station allocates more accurate resources when allocating resources according to the range of the data amount of the data to be transmitted carried in the BS field.

Disclosure of Invention

The application provides a communication method and a communication device, which solve the problem that the base station cannot accurately allocate resources due to the limitation of a BS field.

In a first aspect, the present application provides a communication method, including: the terminal receives the uplink permission information distributed for the terminal from the network equipment. And then, if the uplink permission information is determined to include the identifier of the first LCG, the terminal sends the BSR in the first format to the network equipment through the first LCG according to the preset condition. All fields in the BSR in the first format are used to indicate the data amount of the data to be transmitted.

In a second aspect, the present application provides a communication method, including: after acquiring the identifier of the first LCG, the network device adds the identifier of the first LCG to the uplink permission information. And then, the network equipment sends the uplink permission information to the terminal and indicates the terminal to report the data volume of the data to be transmitted.

In the above scheme, the network device adds the acquired identifier of the first LCG to the uplink grant information, and then sends the uplink grant information to the terminal. And when the terminal determines that the received uplink permission information carries the identifier of the first LCG, the terminal sends the BSR in the first format to the network equipment through the first LCG according to the preset condition. All fields in the BSR in the first format are used to indicate the data volume of the data to be transmitted. Thus, because the network device designates the first LCG for reporting the BSR to the terminal side, the terminal may not carry the first LCG when reporting the BSR _i A field providing more available space for the BS field. Further, all fields in the BSR in the first format are used to indicate the data amount of the data to be transmitted. Thus, compared to including the BS field and the LCG _i The BSR of the field, the range of the data amount of the data to be transmitted in the BSR of the first format, is divided more finely. After receiving the BSR in the first format, the base station allocates more accurate resources when performing resource allocation according to the range of the data amount of the data to be transmitted carried in the BS field.

In a third aspect, the present application provides a communication device for a terminal or a chip on the terminal, including: the acquisition module receives uplink permission information distributed by the network equipment. And then, if the sending module determines that the uplink grant information acquired by the acquisition module includes the identifier of the first LCG, the sending module sends the BSR in the first format to the network device through the first LCG according to a preset condition. All fields in the BSR in the first format are used to indicate the data amount of the data to be transmitted.

In a fourth aspect, the present application provides a communication device, for a terminal or a chip on a terminal, including a processor, where when the communication device is running, the processor executes a computer to execute instructions, so as to cause the communication device to execute the communication method according to the first aspect.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, the meaning of "a plurality" is two or more unless otherwise specified.

Referring to fig. 1, the present application provides a communication system. The communication system includes a network device 101 and a terminal 102.

In particular, terminal 102 may refer to a device that provides voice and/or data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. The terminal 102 may communicate with one or more core networks via a Radio Access Network (RAN). The terminal 102 may be a mobile terminal, such as a mobile telephone (or referred to as a "cellular" telephone). The terminal 102 may be a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges voice and/or data with a radio access network. Such as User Equipment (UE), Personal Communication Service (PCS) phones, Personal Digital Assistants (PDAs), etc.

The network device 101 may be a base station, which may be configured to convert a received air frame into an Internet Protocol (IP) packet, and act as a router between the terminal 102 and the rest of the access network, where the rest of the access network may include an IP network device. The base station may also coordinate management of attributes for the air interface. For example, the base station may be a Base Transceiver Station (BTS) in a global system for mobile communication (GSM) or Code Division Multiple Access (CDMA), a base station (NodeB) in a Wideband Code Division Multiple Access (WCDMA), an evolved Node B (eNB or e-NodeB) in a Long Term Evolution (LTE), or a gbb in a fifth generation mobile communication technology (5th-generation, 5G), which is not limited in the embodiment of the present invention.

Referring to fig. 1, a network device takes a base station as an example, and fig. 2 is a method for a terminal to apply for uplink resources in the prior art. Referring to fig. 2, the method includes:

201. the terminal sends a Scheduling Request (SR) to the base station.

The SR is used to indicate that the base station has data to transmit and needs to transmit.

Specifically, fig. 3 is a method for a terminal to send an uplink scheduling request in the prior art, and as shown in fig. 3, the method includes the following steps.

300. The terminal determines that at least one SR is triggered.

301. The terminal determines whether or not there is an effective Physical Uplink Control Channel (PUCCH) resource.

3011. And if the effective PUCCH resources do not exist, triggering random access on the scell.

302. If the valid PUCCH resource exists, whether an SR prohibit timer (SR-prohibit timer) is started, whether the valid PUCCH resource is overlapped with a measurement gap, and whether the valid PUCCH resource is overlapped with a Physical Uplink Shared Channel (PUSCH) is judged.

3021. If at least one condition exists in step 302, and a result of the condition is met, the PUCCH and Sounding Reference Signal (SRS) of all serving cells are released, Channel State Information (CSI) is cleared to be a semi-persistent PUCCH resource, random access on a scell is initialized, and all pending SRS are cancelled.

After being triggered, the SR is regarded as a pending SR before being cancelled.

303. If all the conditions in step 302 meet the no result, it is determined whether the SR COUNTER (SR _ COUNTER) is less than the SR maximum number (SR-TransMax).

If the SR counter is greater than or equal to the maximum SR number, go to step 3021.

304. If the SR COUNTER is less than the SR maximum number, the SR COUNTER (SR _ COUNTER) is added with 1, the SR is sent to the base station on the effective PUCCH resource, and an SR-ProhibitTimer (SR-ProhibitTimer) is started.

202. And after receiving the SR, the base station issues uplink permission information for the terminal.

203. After receiving the uplink grant information, the terminal reports a Buffer Status Reporting (BSR) to the base station.

The BSR is configured to indicate a data amount of the data to be transmitted, so that the base station allocates transmission resources for the data to be transmitted.

Specifically, the BSR generally includes a BS field and an LCG _i Field, LCG _i The field is used to indicate information related to the LCG, and the BS field is used to indicate the amount of data to be transmitted. Wherein, in the short (short) format BSR and the short truncated (short truncated) format BSR, the LCG _i The field is used for indicating an Identity (ID) of a logical channel group corresponding to the BSR; in the long (long) format BSR, LCG _i A field for indicating whether a BS field of the logical channel group i exists; in the BSR of long truncated (long truncated) format, the LCG _i The field is used to indicate whether there is data to be transmitted in the logical channel group i.

In addition, before reporting the BSR, the terminal may configure a plurality of Logical Channels (LCs) into one LCG according to a policy of the base station, and one terminal may support 8 LCGs at most. After that, the terminal transmits a BSR on the LCG.

Specifically, before reporting the BSR, the terminal needs to determine the type of the triggered BSR. Further, the method for the terminal to trigger the BSR includes the following cases.

A1, when data to be transmitted on a Logical Channel (LC) in the LCG needs to be sent and the priority of the LC is higher than the priority of other LCs that have data to be transmitted, triggering to report a BSR of the "regular BSR" type.

Or, when data to be transmitted on a certain LC needs to be sent and there is no data to be transmitted on other LCs in the LCG where the LC is located, triggering to report the BSR of the "regular BSR" type.

In addition, when a BSR retransmission Timer (retxsbsr-Timer) is overtime and there is data to be transmitted on at least one LC in a certain LCG, reporting of a BSR of the "regular BSR" type is also triggered.

A2, when the terminal determines that the idle resource in the uplink resource allocated to the terminal is greater than or equal to the data overhead of the BSR + header in the uplink grant information issued by the base station, triggering the BSR of the 'padding BSR' type to be reported.

A3, when a BSR periodic Timer (periodicBSR-Timer) is over, triggering the report of BSR of 'periodicBSR' type.

The terminal determines the type of the triggered BSR and then reports the BSR to the base station. Further, the method for reporting the BSR by the terminal includes the following steps.

Specifically, when the terminal triggers and reports the regular BSR and the periodic BSR, the method for the terminal to report the BSR includes:

B. and when more than one LCG has data to be transmitted, reporting the BSR in the long BSR format. Otherwise, reporting the BSR in the short BSR format.

When the terminal triggers and reports the BSR of the 'padding BSR' type, the method for reporting the BSR by the terminal comprises the following steps:

and C1, if it is determined that the idle resource in the uplink resource allocated to the terminal in the uplink permission information transmitted by the base station is equal to the data overhead of the BSR + header in the short BSR format and exceeds a LCG to be transmitted, reporting the BSR in the short truncated BSR format.

And C2, the terminal determines that in the uplink permission information issued by the base station, the idle resource in the uplink resource distributed for the terminal is equal to the data overhead of the BSR + head in the short BSR format, and if only one LCG has data to be transmitted, the BSR in the short BSR format is reported.

And C3, the terminal determines, in the uplink grant information issued by the base station, idle resources in the uplink resources allocated to the terminal, data overhead larger than the BSR + header in the short BSR format and smaller than the BSR + header in the long BSR format, and if more than one LCG has data to be transmitted, reports the BSR in the long found BSR format.

And C4, the terminal determines that, in the uplink permission information issued by the base station, idle resources in the uplink resources allocated to the terminal are greater than or equal to the data overhead of the BSR + header in the long BSR format, and reports the BSR in the long BSR format.

The data volume of the data to be transmitted is carried in the BS field of the BSR. Specifically, in a 5G network, the BS fields of the BSRs in the short BSR format and the short truncated BSR format have 5 bits, and the BS fields of the BSRs in the long BSR format and the long truncated BSR format have 8 bits. In an LTE network, the BS fields of BSRs in the short BSR format and the short truncated BSR format have 6 bits, and the BS fields of BSRs in the long BSR format and the long truncated BSR format have 8 bits. In the embodiment of the present application, the format of the BSR in the 5G network is described, but the present application is also applicable to the format of the BSR in other networks.

More specifically, referring to fig. 4, the contents of the BSR fields in the short BSR format and the short truncated BSR format are the same, and the contents of the BSR fields in the short BSR format and the short truncated BSR format include 3-bit LCG _i A field and a 5-bit BS field. Wherein, LCG _i The field is used for indicating the ID of the LCG corresponding to the data to be transmitted, and the BS field is used for indicating the data volume of the data to be transmitted.

Further, the mapping tables of the short BSR format and the short truncated BSR format are shown in table 1 below. Wherein, BS represents the range of data quantity of data to be transmitted, and the unit is byte; the index represents an indirect indication of the amount of data to be transmitted, and corresponds to the BS in the BSR.

TABLE 1

Index	BS	Index	BS	Index	BS	Index	BS
								0	0	8	≤102	16	≤1446	24	≤20516
1	≤10	9	≤142	17	≤2014	25	≤28581
								2	≤14	10	≤198	18	≤2806	26	≤39818
3	≤20	11	≤276	19	≤3909	27	≤55474
								4	≤28	12	≤384	20	≤5446	28	≤77284
5	≤38	13	≤535	21	≤7587	29	≤107669
								6	≤53	14	≤745	22	≤10570	30	≤150000
7	≤74	15	≤1038	23	≤14726	31	>150000

The contents of the BSRs in the Long BSR format and the Long truncated BSR format are the same as shown in fig. 5, and the contents of the BSRs in the Long BSR format and the Long truncated BSR format include LCGs _i A field and a BS field. Wherein, for BSR in long BSR format, LCG _i The field is used to indicate whether the BS field of the logical channel group i exists. For BSR in the long truncated BSR format, LCG _i The field is used to indicate whether there is data to be transmitted in the logical channel group i.

Further, the mapping tables of the BSRs in the Long BSR format and the Long truncated BSR format are shown in table 2 below, where BS indicates the range of the data amount of the data to be transmitted, and the unit is byte; the index represents an indirect indication of the amount of data to be transmitted, which in the BSR corresponds to the BS.

TABLE 2

From table 1 and table 2 above, it can be seen that: compared with the BSR with the BS field of 5 bits, the range division of the data volume of the data to be transmitted carried in the BSR with the BS field of 8 bits is more fine, namely the BS field is larger, the corresponding BSs are more, and the reported range division of the data volume of the data to be transmitted is more fine. Therefore, after receiving the BSR, the base station allocates more accurate resources when allocating resources according to the range of the data amount of the data to be transmitted carried in the BS field.

Based on the above situation, the present application provides a communication method and apparatus. The communication method specifically comprises the following steps: and the network equipment adds the acquired identifier of the first LCG into the uplink permission information and then sends the uplink permission information to the terminal. And when the terminal determines that the received uplink permission information carries the identifier of the first LCG, the terminal sends the BSR in the first format to the network equipment through the first LCG according to the preset condition. All fields in the BSR in the first format are used to indicate the data volume of the data to be transmitted. Therefore, the terminal can report more information of the data volume of the data to be transmitted to the base station, so that the base station can allocate resources more accurately.

The communication method provided by the embodiment of the present application is applicable to the communication system shown in fig. 1, and each device in fig. 1 belongs to a communication apparatus. In a specific implementation, the communication device has the components shown in fig. 6. Fig. 6 is a schematic composition diagram of a communication device according to an embodiment of the present application, and as shown in fig. 6, the communication device may include a processor 602, where the processor 602 is configured to execute application program codes, so as to implement the communication method in the present application.

The processor 602 may be a general-purpose Central Processing Unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more ics for controlling the execution of programs in accordance with the present disclosure.

As shown in fig. 6, the communication device may further include a memory 603. The memory 603 is used for storing application program codes for executing the scheme of the application, and the processor 602 controls the execution.

The memory 603 may be, but is not limited to, a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a Random Access Memory (RAM) or other type of dynamic storage device that can store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disk storage, optical disk storage (including compact disc, laser disc, optical disc, digital versatile disc, blu-ray disc, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer. The memory 603 may be separate and coupled to the processor 602 via a bus. The memory 603 may also be integrated with the processor 602.

As shown in fig. 6, the communication device may further comprise a communication interface 601, wherein the communication interface 601, the processor 602 and the memory 603 may be coupled to each other, for example, via a bus 604.

The following describes a communication method provided in an embodiment of the present application with reference to the communication system shown in fig. 1 and the communication apparatus shown in fig. 6.

Fig. 7 is a flowchart illustrating a communication method according to an embodiment of the present application. Referring to fig. 7, the communication method includes the following steps.

701. The network device obtains an identifier of the first LCG.

The identifier of the first LCG may be configured for the terminal by the network device actively, or may be obtained from an SR sent by the terminal.

Specifically, when the network device allocates the uplink grant information to the terminal, the following situations are included:

d1, the network equipment actively configures the LCG identifier for the terminal. At this time, the uplink grant information allocated by the network device for the terminal carries an identifier of the first LCG, and the identifier of the first LCG is an identifier for the network device to actively configure the LCG for the terminal.

D2, the network equipment receives the SR of the terminal and triggers the distribution of the uplink permission information. At this time, the uplink grant information allocated by the network device for the terminal carries an identifier of the first LCG, where the identifier of the first LCG is an identifier of an LCG corresponding to SR configuration (SR configuration) corresponding to the received SR.

Specifically, in a 5G network, a specific LCG can be distinguished from an SR configuration corresponding to an SR reported by a terminal. Therefore, the network device may determine the identifier of the first LCG according to the SR configuration corresponding to the SR reported by the terminal.

D3, the network device does not receive the SR of the terminal, and does not configure the identifier of the LCG for the terminal. At this time, the uplink grant information allocated by the network device for the terminal does not carry the identifier of the first LCG.

702. The network device adds the identity of the first LCG to the upstream grant information.

For example, in a 5G network, the network device carries the identifier of the first LCG of 3bit in DCI0_0\ DCI0_1 of the uplink grant information.

703. And the network equipment sends the uplink permission information to the terminal.

704. The terminal determines that the uplink permission information comprises the identifier of the first LCG, and sends the BSR in the first format to the network equipment through the first LCG according to the preset condition.

All fields in the BSR in the first format are used to indicate the data amount of the data to be transmitted.

First, referring to fig. 8, the present application provides a new BSR format, i.e., the BSR in the first format in the present application. The field contents of the BSR in the first format are shown in FIG. 8, including the BS field of 8 bits, excluding the LCG _i A field. The BS field is used to indicate the data amount of data to be transmitted.

Secondly, when the terminal receives the uplink permission information, firstly, whether the uplink permission information carries an identifier of a first LCG is determined, and if the uplink permission information carries the identifier of the first LCG is determined, the BSR in the first format is sent to the network equipment through the first LCG according to preset conditions.

Specifically, referring to fig. 9, the present application provides a method for reporting BSR. The method for reporting the BSR comprises the following steps.

901. The terminal determines whether the uplink grant information includes the identifier of the first LCG.

Specifically, if it is determined that the uplink grant information includes the identifier of the first LCG, the terminal performs step 902. If it is determined that the uplink grant information does not include the identifier of the first LCG, step 9011 is executed.

9011. And the terminal sends the BSR in the second format to the network equipment.

Specifically, the BSRs in the second format include a long BSR, a short truncated BSR, and a long truncated BSR. For a specific way for the terminal to send the BSR in the second format to the network device, refer to step B and steps C1-C4 in the prior art, which are not described herein again.

902. The terminal judges whether the data to be transmitted exist in at least two LCGs.

Specifically, if it is determined that there are data to be transmitted in at least two LCGs, the terminal performs step 903. If it is determined that there is data to be transmitted in only one LCG, the terminal performs step 9021.

9021. The terminal determines that the second LCG has data to be transmitted, and executes step 904.

The terminal corresponds to at least two LCGs, the at least two LCGs comprise a first LCG and a second LCG, and the other LCGs except the second LCG do not have data to be transmitted.

903. The terminal determines whether the idle resources are equal to a first threshold.

The uplink grant information further includes idle resources, and the idle resources are used for transmitting the data volume of the data to be transmitted.

Specifically, if it is determined that the idle resource is equal to the first threshold, the terminal performs step 904. If it is determined that the idle resources are not equal to the first threshold, the terminal performs step 9011. Wherein, the value of the first threshold is 'short BSR' + header overhead.

904. And the terminal sends the BSR in the first format to the network equipment through the first LCG.

In the embodiment of the present application, the communication apparatus may be divided into functional modules according to the method embodiments described above, for example, each functional module may be divided according to each function, or two or more functions may be integrated into one processing module. The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode.
