Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a resource indication method, a determination method, a terminal, and a network device.
Background
In general, when HARQ-ACK (Hybrid Automatic Repeat reQuest ACK, hybrid automatic repeat request acknowledgement) feedback is performed in a mobile communication system, a network device such as a base station and a terminal keep understanding of how many bits of physical resources are occupied for how many bits of HARQ-ACK feedback information are required to be transmitted for uplink. This is determined implicitly by the base station scheduling signaling, or by the protocol according to some rules.
In order to achieve the above objective of keeping the understanding consistent, when the base station performs uplink scheduling PUSCH (Physical Uplink Shared Channel ) transmission, a DCI (Downlink Control Information, downlink control information) for uplink Grant (UL Grant) carries a DAI (Downlink Assignment Index, downlink allocation index) field, that is, total DAI (Total DAI) information, which is used to inform the terminal of the number of bits fed back by HARQ-ACK in the current transmission.
However, in some scenarios, such as future deployments of unlicensed band access, the terminal may be required to utilize unlicensed spectrum for HARQ-ACK feedback in a Listen-before-talk (carrier sense) manner. At this time, due to the requirement of list-before-talk, the channel may be occupied by other terminals for temporary busy, so that the terminals cannot perform HARQ-ACK feedback in time, and thus multiple opportunities for HARQ-ACK feedback need to be introduced to enhance the feedback success rate of the terminals.
Since the HARQ-ACK feedback information actually sent by the terminal at which HARQ-ACK feedback opportunity depends on the busy channel condition, the base station cannot directly determine the HARQ-ACK feedback information, and the Total DAI information needs to be determined before the terminal performs HARQ-ACK feedback, so that the method for indicating the HARQ-ACK feedback resource of the terminal by using the existing Total DAI information cannot meet the requirement of HARQ-ACK feedback of the terminal.

Detailed Description
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings that are needed in the embodiments of the present invention will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and other drawings may be obtained according to these drawings without inventive effort to a person skilled in the art.
Referring to fig. 1, an embodiment of the present invention provides a resource indication method, applied to a network device, where the method includes the following steps:
step 101: and transmitting the Total DAI information to the terminal.
The Total DAI information is used for indicating reservation information of HARQ-ACK feedback resources in a feedback window of the terminal under the condition that the PDSCH corresponds to one or more HARQ-ACK feedback opportunities. As for the above transmission of the Total DAI information to the terminal, it is understood that when the network device performs uplink scheduling PUSCH transmission, the Total DAI information is transmitted through DCI for UL Grant, where the DCI carries the Total DAI information. The above case that the PDSCH corresponds to one or more HARQ-ACK feedback opportunities may be understood that the number of possible HARQ-ACK feedback positions corresponding to the PDSCH may be one or more. The feedback window may be understood as slot.
According to the resource indication method provided by the embodiment of the invention, the Total DAI information is sent to the terminal and is used for indicating the reservation information of the HARQ-ACK feedback resources in the feedback window of the terminal under the condition that the PDSCH corresponds to one or more HARQ-ACK feedback opportunities, so that the terminal can better determine the feedback number of the HARQ-ACK under the condition that the PDSCH corresponds to one or more HARQ-ACK feedback opportunities, and the requirement of the HARQ-ACK feedback of the terminal is timely met.
In the embodiment of the present invention, in order to ensure that the transmission of HARQ-ACK is not prevented for some reasons, for example, the HARQ-ACK corresponding to a PDSCH may be allowed to be fed back at a plurality of time-domain or frequency-domain positions because the channel is detected to be busy by the list-before-talk, and the content indicated by the HARQ timing information (corresponding may be represented as PDSCH-to-HARQ timing indicator) may be expanded to some extent. Specifically, one downlink data transmission (PDSCH) in the current NR system may correspond to one HARQ-ACK feedback position, which is extended to one PDSCH corresponding to one HARQ-ACK feedback position set, where the HARQ-ACK feedback position set may include multiple HARQ-ACK feedback positions, that is, multiple possible HARQ-ACK feedback positions, and the multiple HARQ-ACK feedback positions may be different in the time domain, different in the frequency domain, or different in the time-frequency domain.
For example, the set of HARQ-ACK feedback positions may be denoted as { k } i I=0, 1,..n-1}, i.e. a certain PDSCH can be used forN is a positive integer greater than or equal to 2 for N possible HARQ-ACK feedback positions. And k is i The value of (2) indicates the number of slots of the interval between the PDSCH and the corresponding HARQ-ACK feedback position.
For example, referring to fig. 2, for PDSCH1, PDSCH2 and PDSCH3 transmitted by base station 1 in the specific example of the present invention, 3 possible HARQ-ACK feedback positions may be respectively corresponding, that is, the set of HARQ-ACK feedback positions corresponding to PDSCH1 includes 3 HARQ-ACK feedback positions, the set of HARQ-ACK feedback positions corresponding to PDSCH2 includes 3 HARQ-ACK feedback positions, and the set of HARQ-ACK feedback positions corresponding to PDSCH3 includes 3 HARQ-ACK feedback positions.
It is to be understood that this example is for illustration of embodiments of the invention only and is not intended to limit the embodiments of the invention. In specific implementation, the number of possible HARQ-ACK feedback positions corresponding to different PDSCH sent by the network device may be the same or different. Further, the set of HARQ-ACK feedback positions may include one HARQ-ACK feedback position in addition to a plurality of HARQ-ACK feedback positions, as the case may be.
Specifically, before step 101, the method may further include:
the network device transmits the HARQ timing information to the terminal.
The HARQ timing information is used for indicating a HARQ-ACK feedback position set corresponding to the PDSCH, where the HARQ-ACK feedback position set includes one or more HARQ-ACK feedback positions (i.e., possible HARQ-ACK feedback positions). In particular implementation, the HARQ timing information may be carried by a PDSCH-to-HARQ-timing-indicator indication field included in DL Grant signaling of the network device.
For example, assuming that the network device transmits M PDSCH on a series of symbols, for the jth PDSCH, where j e M may be scheduled by DL Grant signaling including a PDSCH-to-HARQ-timing-indicator indication field, the set of HARQ-ACK feedback positions corresponding to the jth PDSCH is indicated as { k }, the set of HARQ-ACK feedback positions corresponding to the jth PDSCH is determined to be the same as the set of HARQ-ACK feedback positions i,j I=0, 1, ·n-1}, i.e., the jth PDSCH may correspond to N possible HARQ-ACK feedback positions. M may be a positive integer greater than or equal to 2.
And, if the jth PDSCH pairThe slot where the last symbol should be is the nth-q j A slot, the terminal can feed back the HARQ-ACK feedback information corresponding to the jth PDSCH in PUCCH (Physical Uplink Control Channel ) transmission on the nth slot, wherein q is as follows j Is the number of slots belonging to one value in the HARQ-ACK feedback position set, i.e. q j ∈{k i,j I=one value of 0,1, ·n-1.
In the embodiment of the present invention, optionally, the Total DAI information may be used to indicate a sum of numbers of scheduled PDSCH, where at least one HARQ-ACK feedback position of the scheduled PDSCH falls into a feedback window. That is, the Total DAI information may be used to indicate that HARQ-ACK feedback positions corresponding to multiple PDSCH transmitted by the network device are concentrated, and any one of possible HARQ-ACK feedback positions is the sum of the number of scheduled PDSCH that falls in the feedback window.
Alternatively, the Total DAI information may be used to indicate the sum of the numbers of the scheduled PDSCH, where the first HARQ-ACK feedback position in the set of HARQ-ACK feedback positions corresponding to the scheduled PDSCH falls within a feedback window. That is, the Total DAI information may be used to indicate that HARQ-ACK feedback positions corresponding to multiple PDSCH transmitted by the network device are concentrated, and the number of scheduled PDSCH whose first HARQ-ACK feedback position falls within the feedback window among all possible HARQ-ACK feedback positions is summed.
It should be noted that the Total DAI information may be a value X, where X may be equal to or related to the sum of the number of PDSCH scheduled. For example, when the sum of the number of PDSCH scheduled is relatively large, X may be made equal to the sum of the number divided by 8 to obtain a remainder, so that X is represented by 3 bits.
For example, suppose that base station 1 transmits 3 PDSCH, PDSCH1, PDSCH2, and PDSCH3, respectively, with PDSCH1, PDSCH2, and PDSCH3 corresponding to 3 possible HARQ-ACK feedback positions, respectively, as shown in fig. 3.
When at least one HARQ-ACK feedback position of the scheduled PDSCH indicated by the Total DAI information falls into a feedback window, as shown in fig. 3, the base station 1 may transmit the Total DAI information through DCI for UL Grant when performing uplink scheduling PUSCH transmission, and for the feedback window slot1, since there are 1 possible HARQ-ACK feedback positions of the PDSCH1, the corresponding Total DAI information is a value of 1; for feedback window slot2, since there are 1 possible HARQ-ACK feedback positions for PDSCH1 and 1 possible HARQ-ACK feedback position for PDSCH2, the corresponding Total DAI information is a value of 2; for feedback window slot3, since there are 1 possible HARQ-ACK feedback position of PDSCH1, 1 possible HARQ-ACK feedback position of PDSCH2, and 1 possible HARQ-ACK feedback position of PDSCH3, the corresponding Total DAI information may be a value of 3; for feedback window slot4, since there are 1 possible HARQ-ACK feedback positions for PDSCH2 and 1 possible HARQ-ACK feedback position for PDSCH3, the corresponding Total DAI information may be a value of 2; for feedback window slot5, since there are 1 possible HARQ-ACK feedback positions of PDSCH3, the corresponding Total DAI information may be a value of 1.
Or,
when the first HARQ-ACK feedback position in the set of HARQ-ACK feedback positions corresponding to the scheduled PDSCH indicated by the Total DAI information falls into the feedback window, as shown in fig. 4, the base station 1 may send the Total DAI information through the DCI for the UL Grant when performing uplink scheduling PUSCH transmission, and for the feedback window slot1, since there is the first HARQ-ACK feedback position in the set of HARQ-ACK feedback positions corresponding to the PDSCH1, the corresponding Total DAI information is a value of 1; for the feedback window slot2, since there is a first HARQ-ACK feedback position in the set of HARQ-ACK feedback positions corresponding to PDSCH2, the corresponding Total DAI information is a value of 1; for the feedback window slot3, since there is a first HARQ-ACK feedback position in the set of HARQ-ACK feedback positions corresponding to the PDSCH3, the corresponding Total DAI information is a value of 1; for the feedback window slot4, since there is no first HARQ-ACK feedback position in the set of HARQ-ACK feedback positions corresponding to which PDSCH, the corresponding Total DAI information is a value of 0; for feedback window slot5, since there is no first HARQ-ACK feedback position in the set of HARQ-ACK feedback positions corresponding to which PDSCH, the corresponding Total DAI information is a value of 0.
Referring to fig. 5, the embodiment of the invention also provides a resource determining method, which is applied to a terminal, and comprises the following steps:
step 501: receiving Total DAI information from a network device;
step 502: and determining the reservation information of the HARQ-ACK resources in a feedback window according to the Total DAI information.
The Total DAI information is used for indicating reservation information of HARQ-ACK feedback resources in a feedback window of the terminal under the condition that the PDSCH corresponds to one or more HARQ-ACK feedback opportunities.
According to the resource determining method provided by the embodiment of the invention, the Total DAI information is received from the network equipment and is used for indicating the reservation information of the HARQ-ACK feedback resources in the feedback window of the terminal under the condition that the PDSCH corresponds to one or more HARQ-ACK feedback opportunities, so that the terminal can better determine the feedback number of the HARQ-ACK under the condition that the PDSCH corresponds to one or more HARQ-ACK feedback opportunities, and the requirement of the HARQ-ACK feedback of the terminal is timely met.

the HARQ time sequence information is used for indicating a HARQ-ACK feedback position set corresponding to the PDSCH, and the HARQ-ACK feedback position set comprises one or more HARQ-ACK feedback positions.

and when uplink transmission is carried out in the feedback window, determining the number of HARQ-ACK feedback resources in the feedback window according to the Total DAI information.
