Description

Method for transmitting and configuring HARQ-ACK feedback information, corresponding user equipment and base station
Technical Field
The invention relates to the technical field of communication, in particular to a method for transmitting and configuring HARQ-ACK feedback information, corresponding user equipment and a base station.
Background
LTE (Long Term Evolution ) systems support two duplex modes, FDD (Frequency Division Duplexing, frequency division duplex) and TDD (Test Driven Development, time division duplex). Fig. 1 is a frame structure of a TDD system. Each radio frame is 10ms in length and equally divided into two half frames of length 5 ms. Each half frame contains 8 slots of length 0.5ms and 3 special domains, i.e., dwPTS (Downlink Pilot Time Slot ), GP (Guard Period) and UpPTS (Up Pilot Time Slot, uplink pilot time slot), and the sum of the lengths of the 3 special domains is 1ms. The transmission in the LTE system includes: the transmission from the base station to the UE (User Equipment) (referred to as downlink transmission), the corresponding subframe is referred to as downlink subframe, and the transmission from the UE to the base station (referred to as uplink transmission), the corresponding subframe is referred to as uplink subframe.
In downlink communication of an LTE-a (LTE-Advanced, long term evolution technology Advanced) system, reliability of downlink data reception is ensured by HARQ (Hybrid Automatic Repeat reQuest ) technology. The downlink data is transmitted to the UE by the base station through PDSCH (Physical Downlink Shared Channel), and the UE tells the base station through feedback information of HARQ-ACK (Hybrid Automatic Repeat request-Acknowledgement of hybrid automatic repeat request) transmission: whether the UE correctly received the PDSCH. HARQ-ACK information is transmitted by the UE to the base station through PUCCH (Physical Uplink Control Channel ).
For each TB (Transmission Block, transport block) in the received PDSCH, or the received PDCCH (Physical Downlink Control Channel ) indicating SPS (Semi-Persistent Scheduling, semi-persistent scheduling) release, the UE needs to feed back an ACK (correct reception) bit or a NACK (erroneous reception or loss) bit (hereinafter collectively referred to as HARQ-ACK bit) to the base station through the corresponding uplink subframe, and if the base station receives the NACK bit, the base station retransmits the TB corresponding to NACK or the PDCCH indicating SPS release.
In the case of CA (Carrier Aggregation ), since HARQ-ACK feedback information of PDSCH of a plurality of downlink cells and a plurality of downlink slots of each Cell is transmitted in PUCCH of one uplink slot, the downlink Cell transmitting HARQ-ACK in PUCCH of the uplink slot of the same Cell is referred to as one CG (Cell Group), and the number of bits of HARQ-ACK feedback information transmitted in PUCCH of one uplink slot is determined, so that understanding of the base station and UE is consistent.
However, in practical application, if one service cell in one CG supports one TB and one service cell supports two TBs, all service cells are configured to generate two-bit HARQ-ACK feedback information per PDSCH, so that the protocol implementation is relatively simple, however, since only one bit HARQ-ACK feedback information is needed for the PDSCH of the service cell that originally supports one TB, the number of HARQ-ACK bits is additionally increased. In addition, in the NR (New Radio) system, a TB is introduced to include a plurality of CBGs (Code Block groups), and each CBG generates one-bit or two-bit HARQ-ACK feedback information, so that one TB of the PDSCH includes n×m-bit HARQ-ACK feedback information, where N is the number of CBGs included in one TB, and M is the number of HARQ-ACK bits of each CBG. For example, a serving cell without a CBG configured supports one TB, generates one-bit or two-bit HARQ-ACK feedback information, and a serving cell supporting a CBG may contain eight CBGs per TB, generates eight-bit HARQ-ACK feedback information, in which case the number of HARQ-ACK bits generated by all serving cells without a CBG configured needs to be configured from one to eight. However, in this way, the feedback information of HARQ-ACK additionally increases more bits, and the transmission PUCCH also occupies more unnecessary resources.

The embodiment of the application provides a method for determining the number of bits of HARQ-ACK feedback information, as shown in fig. 2, comprising the following steps:
step 210: and determining the grouping of the service cells in the service cell group and the determination mode of the bit number of the HARQ-ACK feedback information corresponding to each grouping according to the received signaling.
The UE may determine, by receiving signaling (e.g., higher layer signaling) sent by the base station, which of the following three methods is adopted for determining the number of bits of the HARQ-ACK feedback information in one CG, where the signaling includes configuration information.
The method comprises the following steps: adopting semi-static state to determine the bit number of HARQ-ACK feedback information of a service cell in one CG;
the second method is as follows: dynamically determining the bit number of HARQ-ACK feedback information of a service cell in one CG;
at this time, DL DAI (DL Downlink Assignment Index, downlink allocation indication) needs to be introduced to assist the base station and the UE in making the understanding of the bit number of the HARQ-ACK feedback information consistent, the DL DAI may include a count DL DAI (called counter DL DAI) and a total DL DAI (called Sum DL DAI, or total DL DAI), where the count DL DAI refers to the current DCI and includes the current DCI, the scheduled PDSCH that the base station has transmitted and the number of PDCCHs indicating release, the total DL DAI refers to the time slot in which the current DCI is located, the scheduled PDSCH that the base station has transmitted and the number of PDCCHs indicating release, and the total DL DAI values in different PDCCHs in the same time slot are the same, as shown in fig. 3, where C-DAI refers to the count DL DAI, and S-DAI refers to the total DL DAI.
In the embodiment of the invention, when the bit number of the HARQ-ACK feedback information is dynamically determined, the bit number of the HARQ-ACK feedback information corresponding to the downlink time slot of the service cell which is configured to be bundled in the packet is bundled.
And a third method: the UE divides the CG service cell into two parts by receiving signaling sent by the base station, the bit number of the HARQ-ACK feedback information of the service cell in the first part is determined through semi-static state, the bit number of the HARQ-ACK feedback information of the service cell in the second part is determined through dynamic state, and the total HARQ-ACK bit number of the service cell in the CG is the sum of the bit number of the HARQ-ACK feedback information of the service cell in the first part and the bit number of the HARQ-ACK feedback information of the service cell in the second part, so that the bit number of the HARQ-ACK feedback information in the CG is determined.
Step 220: and determining the bit number of the HARQ-ACK feedback information of each group of the service cells according to the determination mode of the bit number of the HARQ-ACK feedback information corresponding to each group.
In the embodiment of the present invention, the serving cells in the serving cell group in the same CG are divided into two packets according to the received signaling, where the first packet corresponds to a manner of determining the number of bits of the HARQ-ACK feedback information in a semi-static manner, and the second packet corresponds to a manner of determining the number of bits of the HARQ-ACK feedback information in a dynamic manner.
Determining the bit number of the HARQ-ACK feedback information of each group of service cells in the CG according to the determining mode of the bit number of the HARQ-ACK feedback information corresponding to each group;
the method for determining the bit number of the HARQ-ACK feedback information comprises at least one of the following steps:
semi-statically determining the bit number of the HARQ-ACK feedback information;
the number of bits of the HARQ-ACK feedback information is dynamically determined.
The method for semi-statically determining the bit number of the HARQ-ACK feedback information for the first packet specifically comprises the following steps:
acquiring the number of service cells of the packet, the number of downlink time slots of each service cell transmitting HARQ-ACK feedback information in the same uplink time slot and the bit number of the HARQ-ACK feedback information corresponding to each downlink time slot;
and calculating the bit number of the HARQ-ACK feedback information of the packet according to the number of the service cells, the number of the downlink time slots of each service cell and the bit number of the HARQ-ACK feedback information corresponding to each downlink time slot.
For the second packet, the method for dynamically determining the bit number of the HARQ-ACK feedback information by the UE specifically comprises the following steps:
determining the number of the PDCCHs which are received together according to a downlink allocation indication DL DAI in the received physical downlink control channel PDCCH;
and calculating the bit number of the HARQ-ACK feedback information of the packet according to the number of the PDCCHs and the bit number of the HARQ-ACK feedback information corresponding to each configured PDCCH.
The embodiment of the invention also provides a method for determining the bit number of the HARQ-ACK feedback information, which binds the bit number of the HARQ-ACK feedback information corresponding to the downlink time slot of the service cell which is configured to be bound in any group according to the received signaling;
for the semi-static grouping mode (i.e., the first grouping), the number of bits of HARQ-ACK feedback information corresponding to the downlink time slots of all the service cells that can be bundled is bundled, and the number of bits of HARQ-ACK feedback information of each service cell in the grouping may be the same or different, because different service cells in the subgroup do not require the same number of bits of HARQ-ACK feedback information. And for a dynamic grouping mode (namely a second grouping mode), the number of bits of HARQ-ACK feedback information corresponding to the downlink time slot of the serving cell configured to be bundled in any grouping is bundled, and the number of bits of the HARQ-ACK feedback information of each serving cell in the grouping is similar because different serving cells in the subgroup require similar numbers of bits of the HARQ-ACK feedback information.
Step 230: and obtaining the bit number of the HARQ-ACK feedback information of the service cell group according to the bit number of the HARQ-ACK feedback information of each group of service cells, so as to be used for transmitting the HARQ-ACK feedback information.
Briefly, one method of determining the number of bits of HARQ-ACK feedback information is by semi-static determination by the UE, and another method of determining the number of bits of HARQ-ACK feedback information is by dynamic determination by the UE. The serving cell in the CG may be divided into two parts, e.g. the number of bits of the HARQ-ACK feedback information of the serving cell in one part is determined semi-statically and the number of bits of the HARQ-ACK feedback information of the serving cell in the other part is determined dynamically by reception, the total number of HARQ-ACK bits of the serving cell in the CG being the sum of the number of bits of the HARQ-ACK feedback information of the serving cell in the respective part.
The method for determining the HARQ-ACK feedback information bit number provided by the invention determines the grouping of the service cells in the service cell group and the determination mode of the bit number of the HARQ-ACK feedback information corresponding to each grouping according to the received signaling, for example, a semi-static HARQ-ACK feedback information bit number determination method can be adopted for one part of the service cells, and a dynamic HARQ-ACK feedback information bit number determination method is adopted for the other part of the service cells, so that the service cells do not need to be configured into the same and larger bit number for transmission according to the prior art; determining the bit number of the HARQ-ACK feedback information of each group of service cells in the service cell group according to the determination mode of the bit number of the HARQ-ACK feedback information corresponding to each group; and obtaining the bit number of the HARQ-ACK feedback information of the service cell group according to the bit number of the HARQ-ACK feedback information of each group of service cells so as to be used for transmitting the HARQ-ACK feedback information, reducing the bit number of additional HARQ-ACK feedback information and saving the resource of a PUCCH for transmitting the HARQ-ACK feedback information.
The application also provides a method for configuring the number of HARQ-ACK feedback information bits, as shown in fig. 4, comprising the following steps:
step 401: and configuring the grouping of the service cells in the service cell group and the determination mode of the bit number of the HARQ-ACK feedback information corresponding to each grouping so that the UE determines the bit number of the HARQ-ACK feedback information of each group of the service cells in the service cell group.
Specifically, dividing a service cell in a service cell group into two groups, and configuring a determination mode of the bit number of the HARQ-ACK feedback information of each group, wherein the determination mode comprises at least one of the following: semi-static determination; and (5) dynamically determining. For example, configuring the first packet to employ semi-static determination of the number of bits of HARQ-ACK feedback information; and configuring the second packet to dynamically determine the bit number of the HARQ-ACK feedback information.
Step 402: signaling carrying the packet is sent.
Step 403: and receiving HARQ-ACK feedback information, wherein the HARQ-ACK feedback information is transmitted by the UE based on the bit number of the CG HARQ-ACK feedback information.
The embodiment of the invention also provides a method for configuring the bit number of the HARQ-ACK feedback information, which is used for determining the service cells of the UE needing to bind the bit number of the HARQ-ACK feedback information according to the bit number of the HARQ-ACK feedback information corresponding to the downlink time slots of the service cells; after the service cells to be bundled are distributed to the corresponding groups, so that the bits of the HARQ-ACK feedback information corresponding to the downlink time slots of the service cells are bundled by the UE, the bits of the HARQ-ACK feedback information of each service cell in the groups can be the same or different for a semi-static grouping mode, and the bits of the HARQ-ACK feedback information of each service cell in the groups are similar for a dynamic grouping mode. For example, configuring the serving cells to be bundled in the first packet, so that after the UE bundles the number of bits of HARQ-ACK feedback information corresponding to the downlink time slots of the serving cells to be bundled, the number of bits of HARQ-ACK feedback information of each serving cell in the first packet is the same or different; and configuring the service cells to be bundled in the second packet, so that after the UE bundles the bit number of the HARQ-ACK feedback information corresponding to the downlink time slot of the service cells to be bundled, the bit numbers of the HARQ-ACK feedback information of all the service cells in the second packet are similar.
The connection between the method for configuring the number of bits of the HARQ-ACK feedback information and the method for determining the number of bits of the HARQ-ACK feedback information is, for example, interactive, and will not be described herein.
In order to facilitate understanding of the present application, the following further describes the above technical solution of the present application in a mode of interaction between devices in combination with a specific application case, which is specifically as follows:

The implementation method of the specific HARQ-ACK transmission is as follows:
the UE determines the bit number of HARQ-ACK feedback information in each CG by a method of grouping service cells in each CG;
the UE receives higher layer signaling of the base station to configure at least two downlink service cells (for example, N service cells, where N is a positive integer, N is greater than or equal to 2), where at least one service cell is used to provide PUCCH for transmitting HARQ-ACK of an uplink slot, where the configured N downlink service cells belong to one CG, that is, HARQ-ACK feedback information of the N downlink service cells is transmitted in PUCCH of an uplink slot of one service cell, and the N downlink service cells are divided into two subgroups by higher layer signaling configuration, which are respectively a subgroup one and a subgroup two (the service cells in the subgroup one and the service cells in the subgroup two do not overlap, i.e., any one of the N service cells belongs to either subgroup one or subgroup two, and it is impossible to simultaneously belong to subgroup one and subgroup two), where the number of service cells in the subgroup one is N1, and the number of service cells in subgroup two is N2 (N1 + N2 = 1 and N = 0 = N2 = 2> <n2 >. The HARQ-ACK feedback information of the serving cell in the subgroup I is determined by a semi-static method, and the HARQ-ACK feedback information of the serving cell in the subgroup II is determined by a dynamic method.
For the serving cell in subgroup one, the following method is used to determine the number of HARQ-ACK feedback information bits in subgroup one.
The number of bits of HARQ-ACK feedback information for the UE is determined according to semi-static state, for example, 4 downlink serving cells are configured in the first subgroup, the bundling window of each downlink serving cell is 4, that is, each serving cell has 4 downlink timeslots for transmitting HARQ-ACK feedback information in one uplink timeslot, and the number of bits of HARQ-ACK in each downlink timeslot of each serving cell is 1, so that the total number of bits of HARQ-ACK feedback information for the serving cells in the first subgroup is 4*4 =16 bits, as shown in fig. 5.
For the serving cell in the second sub-cell group, the following method is used to determine the number of HARQ-ACK feedback information bits in the second sub-cell group.
The number of HARQ-ACK feedback information bits of the UE is dynamically determined according to the counted DL DAI and the total DL DAI in the PDCCHs received by the UE, and the counted DL DAI and the total DL DAI are only PDCCH counts for serving cells within the second sub-group.
For example, 4 serving cells are configured in the second subgroup, the HARQ-ACK feedback information of the 4 serving cells is transmitted in an uplink timeslot, the number of bits in the counting DL DAI domain is 2, assuming that the transmission modes of the 4 serving cells all support one TB transmission, and one TB contains 8 coding fast groups, each coding block group generates one bit of HARQ-ACK feedback information, that is, the number of bits of the HARQ-ACK feedback information corresponding to one downlink timeslot of the one serving cell is 8, the total number of bits of the HARQ-ACK transmitted in the PUCCH of one uplink timeslot can be obtained according to the count DL DAI received by the UE and the total number of DL DAI received by the total number, as shown in fig. 6, the UE receives 5 PDCCHs in total, wherein the count DL DAI value is 1,2,3,4,1 total number of DL DAI received in the first timeslot is 1 PDCCH, the total number of DL DAI received is 1, the total number of 2, 4 total number of PDCCH received in total number of PDCCH received is 40 total number of bits of PDCCH received in total number of 4, and the total number of PDCCH received in total number of PDCCH received 4 is 4, and total number of PDCCH received 4 is 4 total number of PDCCH received in total number of 4.
Thus, if the total number of bits of the HARQ-ACK feedback information of the serving cell in the first subgroup is 16 bits and the total number of bits of the HARQ-ACK feedback information of the serving cell in the second subgroup is 40 bits, the total number of bits of the total HARQ-ACK feedback information in the CG is 16+40=56 bits.
Example 2
In this embodiment, a method of bundling HARQ-ACK feedback information (i.e., compression of HARQ-ACK feedback information, for example, spatial bundling of HARQ-ACK feedback information, which is a method of determining the number of bits of HARQ-ACK feedback information in one CG if the number of bits of HARQ-ACK feedback information per slot is 2 for a cell supporting a transmission mode of two TBs without spatial bundling, and if the number of bits of HARQ-ACK feedback information per slot is 1 for a cell supporting a transmission mode of two TBs) is described. In this embodiment, bundling (e.g., spatial bundling) may be configured for all serving cells configured by the UE, that is, if bundling is performed, all cells configured by the UE that support the transmission modes of two TBs are bundled, and if not, all cells configured by the UE that support the transmission modes of two TBs are not bundled. Now, since a case that one TB includes a plurality of code block groups is introduced, and the number of the plurality of code block groups included in each TB of different serving cells may be different, the present embodiment may also be configured independently by the serving cells in configuring whether the serving cells are bundled, for example, the serving cell one in CG one supports a transmission mode of two TBs, and each TB includes four code block groups, and the PDSCH of each time slot generates 8-bit HARQ-ACK feedback information; the serving cell two in CG one supports a transmission mode of two TBs, and where each TB contains eight coded block groups, the PDSCH of each slot generates 16-bit HARQ-ACK feedback information. At this time, if the serving cell one in the CG does not adopt spatial bundling, the PDSCH of each time slot generates 8-bit HARQ-ACK feedback information, and if the serving cell two in the CG adopts spatial bundling, the PDSCH of each time slot generates 8-bit HARQ-ACK feedback information after spatial bundling, so that the number of bits of the HARQ-ACK feedback information generated by the serving cell one in the CG and the PDSCH of each time slot of the serving cell two is the same, the DL DAI with PDCCH as a unit can be used to dynamically determine the number of bits of the HARQ-ACK feedback information.
In this embodiment, the above-mentioned method of determining the number of bits of HARQ-ACK feedback information in one CG is described as determining the number of bits of HARQ-ACK feedback information in each CG, that is, the UE receives signaling of the base station, which is configured to determine the number of bits of HARQ-ACK feedback information in each CG using the method as described above. The implementation method of the specific HARQ-ACK transmission is as follows:
the UE determines the bit number of HARQ-ACK feedback information in each CG by a method of grouping service cells in each CG;
the UE receives higher layer signaling of the base station to configure at least two downlink service cells (for example, N service cells, where N is a positive integer, N is greater than or equal to 2), where at least one service cell is used to provide PUCCH for transmitting HARQ-ACK of an uplink slot, where the configured N downlink service cells belong to one CG, that is, HARQ-ACK feedback information of the N downlink service cells is transmitted in PUCCH of an uplink slot of one service cell, and the N downlink service cells are divided into two subgroups by higher layer signaling configuration, which are respectively a subgroup one and a subgroup two (the service cells in the subgroup one and the service cells in the subgroup two do not overlap, i.e., any one of the N service cells belongs to either subgroup one or subgroup two, and it is impossible to simultaneously belong to subgroup one and subgroup two), where the number of service cells in the subgroup one is N1, and the number of service cells in subgroup two is N2 (N1 + N2 = 1 and N = 0 = N2 = 2> <n2 >. The HARQ-ACK feedback information of the serving cell in the subgroup I is determined by a semi-static method, and the HARQ-ACK feedback information of the serving cell in the subgroup II is determined by a dynamic method.
For the serving cell in subgroup one, the following method is used to determine the number of HARQ-ACK feedback information bits in subgroup one.
The number of bits of HARQ-ACK feedback information for the UE is determined according to semi-static state, for example, 2 downlink serving cells are configured in the subgroup one, the bundling window of each downlink serving cell is 4, that is, each serving cell has 4 downlink timeslots for transmitting HARQ-ACK feedback information in one uplink timeslot, and the number of bits of HARQ-ACK in each downlink timeslot of each serving cell is 1, so that the total number of bits of HARQ-ACK feedback information for the serving cells in the subgroup one is 2×4=8 bits, as shown in fig. 7. For a serving cell within a subgroup one, bundling of HARQ-ACK feedback information may be for all bundling-enabled serving cells within the subgroup (e.g., serving cells supporting transmission modes of two transport blocks), since different serving cells within the subgroup do not require a similar number of HARQ-ACK feedback information bits.
For the serving cell in the second sub-cell group, the following method is used to determine the number of HARQ-ACK feedback information bits in the second sub-cell group.
The number of HARQ-ACK feedback information bits of the UE is dynamically determined according to the counted DL DAI and the total DL DAI in the PDCCHs received by the UE, and the counted DL DAI and the total DL DAI are only counted for PDCCHs of serving cells within the second sub-group (for example, the counted DL DAI and the total DL DAI are each 2 bits in a field), and the correspondence between the counted DL DAI and the total DL DAI value and the PDSCH and the number of PDCCHs indicating SPS release is shown in table 1. Where N in table 1 (N is a positive integer) relates to the number of serving cells supported by the UE.
Table 1: mapping relation between count DL DAI and total DL DAI value and PDSCH and PDCCH number indicating SPS release
For example, 2 serving cells are configured in the second subgroup, HARQ-ACK feedback information of the 2 serving cells is transmitted in one uplink timeslot, the number of bits in the count DL DAI field is 2, the number of bits in the total DL DAI field is 2, it is assumed that the transmission mode of the third serving cell supports two TB transmissions, and one TB includes 4 coded bursts, each coded burst generates one bit of HARQ-ACK feedback information, i.e., the number of bits of HARQ-ACK feedback information corresponding to one downlink timeslot of the third serving cell is 8, the transmission mode of the fourth serving cell supports two TB transmissions, and one TB includes 8 coded bursts, and each coded burst generates one bit of HARQ-ACK feedback information, i.e., the number of bits of HARQ-ACK feedback information corresponding to one downlink timeslot of the fourth serving cell is 16, as shown in fig. 8.
The HARQ-ACK feedback information of the serving cell four may be spatially bundled, where the number of bits of the HARQ-ACK feedback information of one downlink slot of the serving cell four after spatially bundling is 8, so that the count DL DAI and the total number DL DAI with PDCCH as a unit are adopted in the subgroup two. The total number of bits of HARQ-ACKs transmitted in the PUCCH of one uplink slot may be obtained according to the counted DL DAI and the total number DL DAI received by the UE, as shown in fig. 9, in the case of the counted DL DAI and the total number DL DAI in the PDCCH received by the UE, the UE receives 5 PDCCHs in total, wherein the counted DL DAI values are 1,2,3,4,1, respectively, the total number DL DAI value is 1 for one PDCCH received in the first slot, the total number DL DAI is 1 for the two PDCCHs received in the second slot, the total number DL DAI is 3 for the two PDCCHs received in the fourth slot, the total number of received 5 PDCCHs may be calculated, each PDCCH scheduled PDSCH generates 8-bit HARQ-ACK feedback information, and the total number of bits of HARQ-ACK feedback information is 5*8 =40. For serving cells within subgroup two, bundling of HARQ-ACK feedback information may be independently determined for each serving cell within the subgroup as to whether to spatially bundle (e.g., whether to spatially bundle each serving cell via independent higher layer signaling) because different serving cells within the subgroup require a similar number of HARQ-ACK feedback information bits.
Thus, if the total number of bits of the HARQ-ACK feedback information of the serving cell in the first subgroup is 8 bits and the total number of bits of the HARQ-ACK feedback information of the serving cell in the second subgroup is 40 bits, the total number of bits of the total HARQ-ACK feedback information in the CG is 8+40=48 bits.
