Description

Transmission and SR state determination method and equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for determining a transmission and SR state.

Background

Currently, in a 5 th Generation wireless communication (5Generation New RAT, 5G NR) system, 5 Physical Uplink Control Channel (PUCCH) formats (formats) are defined, namely, PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format3, and PUCCH format 4. Different PUCCH formats are applicable to different transmission schemes, wherein PUCCH format 0 and PUCCH format 1 are used for transmitting UCI with the length not greater than 2 bits, and PUCCH format 2, PUCCH format3 and PUCCH format 4 are used for transmitting UCI with the length greater than 2 bits. The PUCCH may be configured to transmit Uplink Control Information (UCI), and the UCI may include Hybrid Automatic Repeat ReQuest-ACKnowledgement (HARQ-ACK) Information, Channel State Information (CSI), and Scheduling ReQuest (SR). When the transmission time of the HARQ-ACK and/or CSI overlaps with the transmission time of the SR in the time domain, 1-bit information may be used to indicate the state of the SR, for example, 1 indicates a positive (positive) SR, and 0 indicates a negative (negative) SR, where the 1-bit SR information may be concatenated with the HARQ-ACK and/or CSI, jointly encoded, and then simultaneously transmitted on the resources of PUCCH format 2, PUCCH format3, or PUCCH format 4.

However, in the current 5G NR system, a base station (gnnodeb, gNB) may configure multiple SR configurations for a terminal, and different SR configurations are suitable for different traffic types and/or transmission requirements. Wherein one or more parameters in different SR configurations are different, e.g., SR resources or periods in different SR configurations may be different. However, when the positive SR sent by the terminal is cascaded with the HARQ-ACK and/or the CSI for transmission, the base station cannot determine which SR the positive SR sent by the terminal corresponds to, so that the base station cannot perform a subsequent communication process in time, and communication experience of a user is affected.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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.

The technical background of the embodiments of the present invention is described below.

In the current 5G NR system, a base station (gbnodeb, gNB) may configure multiple SR configurations for a terminal, and different SR configurations are suitable for different service types and/or transmission requirements. Wherein one or more parameters in different SR configurations are different, e.g., SR resources or periods in different SR configurations may be different. However, when the positive SR sent by the terminal is cascaded with the HARQ-ACK and/or the CSI for transmission, the base station cannot determine which SR the positive SR sent by the terminal corresponds to, so that the base station cannot perform a subsequent communication process in time, and communication experience of a user is affected.

In view of this, an embodiment of the present invention provides an SR determining method, in which a terminal may determine, before transmission of a first UCI, indication information for indicating SR states of multiple SR configurations of the terminal, and indirectly notify, by means of CRC scrambling of the first UCI, the indication information to a base station, so that even when transmission of SRs corresponding to SR configurations of the terminal is overlapped and the SRs and HARQ-ACK and/or CSI are concatenated together for transmission, the base station may know the SR configuration corresponding to a positive SR sent by the terminal, thereby ensuring that the base station can continue to perform a subsequent communication process, and improving communication experience of a user.

The technical scheme provided by the embodiment of the invention is described below by combining the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention provides a transmission method, which may be performed by a terminal, and the terminal may be implemented by a device capable of communicating with a base station, such as a Personal Computer (Personal Computer), a mobile phone, or a tablet Computer. The process of the method is described below, wherein in the following process, a description of the method on the base station side is also referred to.

S101: the terminal determines the indication information of M bits.

In the embodiment of the present invention, the base station may configure at least one SR configuration for the terminal, and one or more parameters included in different SR configurations are different. A Media Access Control (MAC) layer of the terminal may notify the terminal of which passive SR configured by the SR needs to be transmitted in one SR transmission opportunity, and the terminal may transmit the passive SR to the base station. In practical application, transmission opportunities configured by multiple SRs may overlap in a time domain, when the transmission opportunities configured by multiple SRs overlap, the MAC of the terminal may notify the terminal to transmit one of the passive SRs configured by the SRs, and if the terminal selects to cascade the passive SR to be transmitted and the first UCI to be transmitted together for transmission, in order to enable the base station to determine the passive SR specifically configured by the SR that is transmitted by the terminal, the terminal may carry indication information in the first UCI, so that the base station can determine according to the indication information.

In the embodiment of the present invention, the terminal may first determine whether the current time is a transmission opportunity of the SR, or the terminal may first determine whether the current time is a transmission opportunity of the SR, and whether at least 2 SR configurations exist in the transmission opportunity. If the terminal determines the transmission opportunity of which the current time is the SR, or the terminal determines the transmission opportunity of which the current time is the SR and at least 2 SR configurations exist in the transmission opportunity, the terminal may determine the indication information.

Specifically, the first UCI includes hybrid automatic repeat request acknowledgement HARQ-ACK and/or channel state information CSI. For example, if the terminal corresponds to two SR configurations, that is, SR configuration 1 and SR configuration 2, and according to the period and offset value configured for SR configuration 1 and SR configuration 2, the transmission times of SR1 and SR2 corresponding to SR configuration 1 and SR configuration 2 will overlap at time 1, and there is a HARQ-ACK transmission of 16 bits at time 1, the terminal may carry indication information in the HARQ-ACK to notify the base station of the passive SR configured for which SR the terminal transmits.

In the embodiment of the present invention, before the terminal performs transmission of the first UCI, it first needs to determine M-bit indication information, where the indication information is used to indicate SR states of multiple SR configurations of the terminal, and M is an integer greater than 1. There are various specific implementations of the indication information, and the implementations of the indication information will be described separately below.

In the embodiment of the present invention, the terminal may determine the indication information according to an SR state of each SR configuration of the plurality of SR configurations of the terminal. One bit in the indication information may correspond to one SR configuration, and one bit is used to indicate that the SR configuration corresponding to the bit is in a positive SR state or a negative SR state. Wherein the positive SR state represents that the SR configuration is a triggered SR configuration, and the negative SR state represents that the SR configuration is an un-triggered SR configuration.

Specifically, when the indication information is implemented by this implementation manner, a value of M bits included in the indication information may be related to the number of SR configurations corresponding to the terminal. For example, the value of M may be a maximum value of the number of SR configurations that the base station can configure for the terminal, where if the number of SR configurations that the terminal is actually configured for is less than the maximum value, which is equivalent to that some bits in M bits are not used in a reserved state, bit positions of the M bits may be set to a specific value that is agreed with the base station, for example, "0" or "1"; or, the value of M may be the number of SR configurations configured by the base station for the terminal; or, the value of M may be the number of SR configurations that the base station overlaps with transmission opportunities in a plurality of SR configurations configured for the terminal. Of course, the base station may also notify the value of the terminal M in advance, that is, the value of M may also be the number notified to the terminal by the base station through the configuration signaling.

Specifically, the indication information may correspond to a preset arrangement order of the plurality of SR configurations based on the plurality of SR configurations, wherein the preset arrangement order may be related to an index of the SR configuration. For example, if the sequence order may be an ascending order or a descending order of the indexes of the SR configurations, the first bit to the last bit of the M bits included in the indication information respectively correspond to at least one SR configuration in the ascending order or the descending order of the indexes of the SR configurations. Specifically, the terminal may also correspond to at least one SR configuration according to other possible sequences, which is not limited in this embodiment of the present invention.

Specifically, the indication information may correspond to a plurality of SR configuration information based on the correspondence indicated by the base station. The base station may notify the terminal of the correspondence in advance, and the terminal may correspond to the at least one SR configuration according to the correspondence indicated by the base station. For example, the base station notifies the terminal of the indexes of the SR configurations corresponding to the first bit to the last bit included in the indication information, and the terminal determines the ordering order of the indication information according to the order notified by the base station.

Following the above example of two SR configurations, the terminal corresponds to the two SR configurations, and then the terminal may determine the value of M as 2, that is, the indication information includes 2 bits. If the terminal uses 0 to represent the negative SR state and 1 to represent the positive SR state, assuming that the SR that needs to send the positive SR is configured as SR configuration 1, the indication information may be represented as "10"; or the terminal uses 1 to indicate the negative SR state, 0 to indicate the positive SR state, and if the SR configuration that needs to transmit the positive SR is SR configuration 1, the indication information may be indicated as "01".

In the embodiment of the present invention, the SR configuration in which only one bit corresponds to the indication information is configured as the positive SR state. Specifically, because only one SR configuration of the positive SR is transmitted by the terminal at the same time, only the SR configuration corresponding to 1 bit in the indication information finally determined by the terminal is in the positive SR state, and the SR configurations corresponding to M-1 bits except for the 1 bit are all in the negative SR state. Of course, if there are multiple SR configurations that the terminal can transmit the positive SR at the same time, the indication information may also have SR configurations corresponding to multiple bits in the positive SR state, which is not limited in this embodiment of the present invention.

In the embodiment of the present invention, the terminal may further determine the indication information according to a preset corresponding relationship between the plurality of SR configurations and a plurality of indication information states of the indication information. The first indication information state in the indication information is used for indicating that each SR configuration in the plurality of SR configurations is a negative SR state, a part or all of the indication information states except the first indication information state in the indication information are used for indicating that the SR configuration corresponding to the part or all of the indication information states is a positive SR state, wherein the first indication information state is any indication information state in the indication information.

Specifically, when the indication information is implemented by this implementation manner, the value of M bits included in the indication information may also be related to the number of SR configurations corresponding to the root terminal. For example, the value of M may be determined by the maximum value a1 of the number of SR configurations that the base station can configure for the terminal; or the value of M is determined by the number a2 of SR configurations configured by the base station for the terminal; or, the number of SR configurations a3 that overlap in the time domain according to the transmission time instant in at least one SR configuration. Wherein, the value calculation formula of M is M ═ ceil (log)₂(Ai +1)), where ceil denotes rounding up and Ai is A1, A2, or A3. Of course, the base station may also notify the value of the terminal M in advance, that is, the value of M may also be the number notified to the terminal by the base station through the configuration signaling.

Referring to table 1, when the number of SR configurations corresponding to the terminal is 3, that is, SR configuration 1 to SR configuration 3, the terminal may determine that the value of M is 2, and 2 bits may indicate 4 different values, that is, it is completely sufficient to correspond to 3 SR configurations.

Indicating information	Indicating the content indicated by the information
		00	All SR configurations are Negative SR states
01	SR configuration 1 is a positive SR state
		10	SR configuration 2 is a positive SR state
11	SR configuration 3 is a positive SR state

TABLE 1

In the embodiment of the present invention, if a partial indication information state in the indication information states other than the first indication information state in the indication information is used to indicate that the SR corresponding to the partial indication information state is configured as a positive SR state, the remaining indication information state in the indication information is a reserved state. For example, when the number of SR configurations is 2, the corresponding relationship in table 1 may also be utilized, and it is only necessary to set the last indication information to the reserved state, that is, "11" is not used to indicate any content.

Referring to table 2, when the number of SR configurations corresponding to the terminal is 7, that is, SR configuration 1 to SR configuration 7, the terminal may determine that the value of M is 3, and may show 8 different values through 3 bits, that is, it is completely sufficient to correspond to 7 SR configurations.

TABLE 2

When the number of SR configurations corresponding to the terminal is less than 7, the corresponding relationship in table 2 may also be used, and only the remaining indication information needs to be set to the reserved state, that is, the indication information set to the reserved state is not used to indicate any content.

Following the above example of two SR configurations, the terminal corresponds to the two SR configurations, and then the terminal may determine the value of M as 2, that is, the indication information includes 2 bits. Assuming that the SR transmitting the positive SR is configured as SR configuration 1, the terminal may determine that the indication information is "01" according to the correspondence relationship of table 1.

S102: the terminal scrambles Cyclic Redundancy Check (CRC) information of the first UCI by the indication information.

In the embodiment of the present invention, after the terminal determines the indication information, the indication information may be carried in the first UCI. The terminal can scramble the CRC of the first UCI through the indication information, so that the first UCI indirectly carries the indication information. The CRC may include N bits, where N ≧ M.

Specifically, when the CRC is scrambled, the preset M-bit information in the CRC may be scrambled by the indication information. The preset M-bit information may be high M-bit information or low M-bit information in the CRC, and may also be any M-bit information in the CRC. Specifically, the scrambling may be performed by performing a modulo two addition operation on the high M-bit information or the low M-bit information of the CRC and the M-bit indication information, that is, performing a bit addition operation on the M-bit of the indication information and the M-bit of the CRC, and then performing a modulo 2 operation.

Specifically, when the first UCI includes CSI, the CSI may be composed of multiple parts, for example, the CSI may include a first part CSI (CSI part1) and a second part CSI (CSI part2), and then when the CRC of the CSI is scrambled by the indication information, the CRC corresponding to CSI part1 or CSI part2 may be scrambled. Wherein the CSI may be one or more of periodic CSI, aperiodic CSI, and semi-persistent scheduling CSI.

Specifically, in a set case, the UCI may have a corresponding CRC only when the length of the UCI is greater than 11 bits, and thus, the length of the first UCI may be greater than 11 bits. Wherein, different length ranges of the UCI may correspond to different CRC lengths. For example, when the length of the UCI is 12 to 19 bits, the length of the CRC corresponding to the UCI is 6 bits; or, when the length of the UCI is greater than 19 bits, the length of the CRC corresponding to the UCI is 11 bits.

Following the two SR configurations, if the SR configuration in which the terminal sends the positive SR is SR configuration 1, and the CRC corresponding to the HARQ-ACK to be transmitted at time 1 is 6 bits, for example, the CRC may be 110010.

Specifically, if the terminal determines the indication information according to the SR state of each SR configuration of the plurality of SR configurations of the terminal, for example, the indication information determined by the terminal is 10, the terminal may scramble the CRC corresponding to the HARQ-ACK through the indication information, for example, the terminal may scramble the upper 2 bits (MSB) of the CRC, that is, the upper 2 bits are "11" and perform a modular two-way addition operation with the indication information "10" to obtain "01", so that the scrambled CRC is "010010"; alternatively, the terminal may scramble the lower 2 bits (LSB) of the CRC, that is, the lower 2 bits are "10" and the indication information "10" is subjected to modulo two addition to obtain "00", so that the scrambled CRC is "110000".

Specifically, if the terminal determines the indication information according to the preset correspondence between the SR configurations and the indication information states of the indication information, then the terminal may determine that the indication information is "01" according to the correspondence in table 1, and then the terminal may scramble the CRC corresponding to the HARQ-ACK by using the indication information, for example, the terminal may scramble the higher 2 bits of the CRC, that is, the higher 2 bits are "11" and perform modulo two addition with the indication information "01" to obtain "10", so that the scrambled CRC is "100010"; alternatively, the terminal may scramble the lower 2 bits of the CRC, that is, the lower 2 bits are "10" and the indication information "01" are subjected to modulo two addition to obtain "00", so that the scrambled CRC is "110011".

S103: and the terminal sends the scrambled first UCI to the base station, and the base station receives the scrambled first UCI.

In the embodiment of the invention, after the terminal obtains the scrambled first UCI, the scrambled first UCI can be sent to the base station. Since the length of the scrambled first UCI is greater than 2 bits, the terminal may transmit the first UCI to the base station through the first PUCCH format. The first PUCCH format may be PUCCH format 2, PUCCH format3, PUCCH format 4, or another PUCCH format with bearer capability greater than 2 bits. Correspondingly, when receiving, the base station also receives the scrambled first UCI on the transmission resource of the first PUCCH format.

For example, following the above example, after scrambling the CRC corresponding to the HARQ-ACK by the terminal, the terminal may directly send the HARQ-ACK to the base station, so that the base station may also know, through the CRC corresponding to the HARQ-ACK, the SR configuration corresponding to the positive SR sent by the terminal, that is, since the terminal HARQ-ACK already indirectly carries the indication information, the SR does not need to be sent to the base station. Of course, the terminal may also concatenate the SR and the HARQ-ACK together to send to the base station according to the existing mechanism based on the above CRC scrambling, where the SR may use 1 bit to represent the positive SR or the negative SR, and as to which SR configuration the positive SR specifically corresponds to, may indirectly know through the indication information carried by the CRC of the HARQ-ACK.

Of course, the embodiment of the present invention is not limited to scrambling HARQ-ACK, and may also scramble HARQ-ACK and/or CSI, that is, if HARQ-ACK and CSI exist at the same time, an information sequence obtained by concatenating HARQ-ACK and CSI may be subjected to channel coding to obtain a corresponding CRC sequence, and the above scrambling process may be performed on the CRC sequence.

S104: and the base station acquires the M-bit indication information for scrambling the CRC of the first UCI according to the first UCI.

In the embodiment of the present invention, after receiving the scrambled first UCI, the base station may obtain a CRC corresponding to the UCI. The base station can perform trial descrambling on the preset M-bit information of the CRC through M bits corresponding to different SR configurations, and obtain the indication information corresponding to the CRC which can pass the CRC check.

Specifically, following the above two SR configurations, if the terminal determines the indication information according to the SR state of each SR configuration in the plurality of SR configurations of the terminal, the base station may obtain CRC corresponding to HARQ-ACK, that is, "110000", after receiving the HARQ-ACK. Wherein, the base station and the terminal can determine the mode adopted by the indication information in advance, if the terminal determines the indication information according to the SR state of each SR configuration in a plurality of SR configurations of the terminal, the base station also knows the mode adopted by the indication information of the terminal, that is, the base station may determine that the indication information may be "00", "01", "10", and "11", the base station may attempt to descramble the CRC with these several possible indications, e.g., when the terminal scrambles the upper 2 bits of the CRC, the base station may attempt to descramble the upper 2 bits of the CRC, i.e. the high 2 bits are "11", respectively, and the above-mentioned possible indication information are undergone the process of modular two-addition operation, then the CRC check is implemented by means of CRC after descrambling, the indication information corresponding to the CRC which can pass the CRC check is indication information corresponding to the SR configuration corresponding to the positive SR sent by the terminal. For example, in the above possible indication information, only the CRC "110010" obtained after descrambling is attempted by "10" is the original CRC of the terminal, that is, only the CRC can pass the CRC check, and then the base station may determine that the indication information corresponding to the SR configuration corresponding to the positive SR sent by the terminal is "10". The process of descrambling at the base station side when the terminal scrambles the lower two bits or scrambles any other two bits is similar, and therefore, the description is omitted here.

Specifically, following the above two SR configurations, if the terminal determines the indication information according to the preset corresponding relationship between the SR configurations and the indication information states of the indication information, the base station may obtain the CRC corresponding to the HARQ-ACK, that is, "110011", after receiving the HARQ-ACK. Meanwhile, the base station may also determine that the indication information may be "00", "01", "10", and "11", and then the base station may perform trial descrambling on the CRC through the several possible indication information, for example, when the terminal scrambles the high 2 bits of the CRC, the base station may perform trial descrambling on the high 2 bits of the CRC, that is, the high 2 bits are "11", respectively perform modulo two addition operation with the possible indication information, and then perform CRC check through the descrambled CRC, where the indication information corresponding to the CRC that can pass the CRC check is the indication information corresponding to the SR configuration corresponding to the positive SR sent by the terminal. For example, in the above possible indication information, only the CRC "110010" obtained after descrambling is attempted by "01" is the original CRC of the terminal, that is, only the CRC can pass the CRC check, and then the base station may determine that the indication information corresponding to the SR configuration corresponding to the positive SR sent by the terminal is "01". The process of scrambling the lower two bits or scrambling any other two bits by the terminal is similar, and therefore, the description is omitted here.

Specifically, when the first UCI includes CSI, and the CSI may be composed of multiple parts, for example, the CSI may include CSI part1 and CSI part2, and if the terminal scrambles the CRC of CSI part1, the base station may perform trial descrambling on the CRC of CSI part 1; or if the terminal scrambles the CRC of the CSI part2, the base station tries to descramble the CRC of the CSI part 2.

S105: and the base station determines the SR states of the plurality of SR configurations of the terminal according to the indication information.

In the embodiment of the present invention, after the indication information is obtained by the base station, the SR states of the multiple SR configurations of the terminal may be determined according to the indication information, and then the service requirement corresponding to the SR configuration corresponding to the positive SR sent by the terminal is determined according to the SR states of the multiple SR configurations, so as to perform corresponding uplink scheduling on the terminal.

Specifically, if the terminal determines the indication information according to the SR state of each SR configuration of the plurality of SR configurations of the terminal, the base station may determine the SR state of each SR configuration according to the indication information. For example, if the indication information acquired by the base station is "10", and if the previous bit corresponds to SR configuration 1, the next bit corresponds to SR configuration 2, and "1" indicates a positive SR configuration, and "0" indicates a negative SR configuration, the base station may determine that SR configuration 1 corresponding to the previous bit is in a positive SR state, and SR configuration 2 corresponding to the next bit is in a negative SR state.

Specifically, if the terminal determines the indication information according to the preset corresponding relationship between the SR configurations and the indication information states of the indication information, the base station may search for the SR configuration corresponding to the indication information in the preset corresponding relationship according to the obtained indication information. For example, if the indication information acquired by the base station is "01", and the content represented by "01" is that SR configuration 1 is in a positive SR state according to the corresponding relationship in table 1, the base station may determine that the SR configuration corresponding to the positive SR sent by the terminal is SR configuration 1.

In the embodiment of the present invention, if the terminal determines that there is no SR with overlapping transmission opportunities, that is, there is only one SR configuration triggered in one SR transmission opportunity, and there are other UCI waiting for transmission in the transmission opportunity, the terminal may also transmit the SR according to other agreed manners instead of the above method. Specifically, the terminal may implicitly notify the base station that the SR configuration corresponding to the positive SR sent by the terminal is the SR configuration corresponding to the SR resource by transmitting other UCI on the SR resource corresponding to the SR configuration that notifies that the positive SR needs to be sent.

For example, at time 2, the SR that the terminal needs to transmit is only SR1, then at time 2, the SR configuration corresponding to the positive SR is only SR configuration 1, and then when SR configuration 1 needs to send the positive SR, the terminal may implicitly express that SR configuration 1 sends the positive SR by transmitting other UCI on the SR resource corresponding to SR configuration 1; or, whether SR configuration 1 is a positive SR configuration or not, since the SR configuration for transmitting the positive SR at time 2 is only SR configuration 1, the base station may determine the SR configuration corresponding to the positive SR transmitted at time 2, and therefore the terminal may cascade the 1-bit SR with other UCI at time 2 and transmit the same on resources corresponding to the other UCI. This may reduce the effect of scrambling on the CRC of other UCI, as compared to performing the above method each time an SR needs to be transmitted. Although the used transmission schemes may be different when different SRs are transmitted, the base station and the terminal always agree with specific information of a plurality of SR configurations, for example, a period, and both the base station and the terminal can know the overlapping condition of the SR configurations in advance, so as to determine to select a corresponding transmission scheme for transmission, and there is no case where the transmission scheme determined by the base station is different from the transmission scheme of the terminal.

In the embodiment of the present invention, the above description only takes the overlapping transmission of SR and HARQ-ACK as an example, that is, the first UCI is HARQ-ACK, but it should be understood that the first UCI may also be CSI or the case where HARQ-ACK and CSI exist at the same time, and the above method is also applicable to this case. When the CSI and the HARQ-ACK exist at the same time, the CSI can be transmitted through PUCCH format 2, PUCCH format3 or PUCCH format 4, and the HARQ-ACK can be transmitted through PUCCH format 0 or PUCCH format 1; or, the HARQ-ACK and the CSI are transmitted simultaneously through PUCCH format 2, PUCCH format3 or PUCCH format 4.

In summary, in the embodiments of the present invention, before the transmission of the first UCI, the terminal may determine the indication information for indicating the SR states of the multiple SR configurations of the terminal, and indirectly notify the base station of the indication information in a CRC scrambling manner for the first UCI, so that even when the transmissions of the SRs corresponding to the SR configurations of the terminal overlap and the SRs are concatenated with the HARQ-ACK and/or the CSI for transmission, the base station can know the SR configuration corresponding to the positive SR sent by the terminal, thereby ensuring that the base station can continue to perform the subsequent communication process, and thus improving the communication experience of the user.
