Abstract

Information sending methods and devices are described. In examples of the present disclosure, a network device may schedule a first downlink subframe in a downlink subframe set of a terminal. The network device then a sum field and a first indication field to the terminal. The network device first feedback information in an uplink subframe for the first downlink subframe in the downlink subframe set.

First claim

What is claimed is:

1. An information receiving method, comprising:
scheduling, by a network device, a first downlink subframe in a downlink subframe set of a terminal;
sending, by the network device, a sum field and a first indication field to the terminal; and
receiving, by the network device, first feedback information in an uplink subframe for the first downlink subframe in the downlink subframe set;
wherein:
feedback information for each downlink subframe in the downlink subframe set is fed back in the uplink subframe,
the first indication field indicates a total quantity of downlink subframes in the downlink subframe set, and
the sum field indicates a total quantity of downlink subframes whose numbers are equal to the subframe number of the first downlink subframe and that are in the downlink subframe set, and downlink subframes before the first downlink subframe and that are in the downlink subframe set.

2. The method according to claim 1 , further comprising:
sending, by the network device, an index field on a downlink control channel, wherein a value of the index field is a count value obtained by performing accumulative counting in a carrier-first and subframe second order in the downlink subframe set.

3. The method according to claim 2 , wherein the sum field is carried on the downlink control channel.

4. The method according to claim 1 , wherein the first indication field is in an uplink scheduling grant (UL_grant).

5. The method according to claim 1 , further comprising:
sending, by the network device, an index field on a downlink control channel,
wherein a value of the index field denotes an accumulative counting value of downlink subframes in the downlink subframe set, up to the first downlink subframe and a first carrier on which the first downlink subframe is located, first in increasing order of carrier number and then in increasing order of subframe number.

6. The method according to claim 1 , wherein the downlink subframe set is a subset of a preconfigured downlink subframe set, and the preconfigured downlink subframe set is configured for the terminal and includes all downlink subframes on all carriers corresponding to the uplink subframe.

7. An apparatus, comprising:
one or more processors, and
a non-transitory storage medium configured to store program instructions that when executed by the one or more processors cause the apparatus to:
schedule a first downlink subframe in a downlink subframe set of a terminal;
send a sum field and a first indication field to the terminal; and
receive first feedback information in an uplink subframe for the first downlink subframe in the downlink subframe set;
wherein:
feedback information for each downlink subframe in the downlink subframe set is to be fed back in the uplink subframe,
the first indication field indicates a total quantity of downlink subframes in the downlink subframe set, and
the sum field indicates a total quantity of downlink subframes whose numbers are equal to the subframe number of the first downlink subframe and that are in the downlink subframe set, and downlink subframes before the first downlink subframe and that are in the downlink subframe set.

8. The apparatus according to claim 7 , wherein the program instructions further cause the apparatus to:
send an index field on a downlink control channel, wherein a value of the index field is a count value obtained by performing accumulative counting in a carrier-first and subframe second order in the downlink subframe set.

9. The apparatus according to claim 8 , wherein the sum field is carried on the downlink control channel.

10. The apparatus according to claim 7 , wherein the first indication field is in an uplink scheduling grant (UL_grant).

11. The apparatus according to claim 7 , wherein the program instructions further cause the apparatus to:
send an index field on a downlink control channel,
wherein a value of the index field denotes an accumulative counting value of downlink subframes in the downlink subframe set, up to the first downlink subframe and a first carrier on which the first downlink subframe is located, first in increasing order of carrier number and then in increasing order of subframe number.

12. The apparatus according to claim 7 , wherein the downlink subframe set is a subset of a preconfigured downlink subframe set, and the preconfigured downlink subframe set is configured for the terminal and includes all downlink subframes on all carriers corresponding to the uplink subframe.

13. A non-transitory computer-readable medium having program instructions recorded thereon, wherein, when the instructions are executed by a processor in a network device, the instructions cause the network device to:
schedule a first downlink subframe in a downlink subframe set of a terminal;
send a sum field and a first indication field to the terminal; and
receive first feedback information in an uplink subframe for the first downlink subframe in the downlink subframe set;
wherein:
feedback information for each downlink subframe in the downlink subframe set is to be fed back in the uplink subframe,
the first indication field indicates a total quantity of downlink subframes in the downlink subframe set, and
the sum field indicates a total quantity of downlink subframes whose numbers are equal to the subframe number of the first downlink subframe and that are in the downlink subframe set, and downlink subframes before the first downlink subframe and that are in the downlink subframe set.

14. The apparatus according to claim 13 , wherein the instructions further cause the network device to:
send an index field on a downlink control channel, wherein a value of the index field is a count value obtained by performing accumulative counting in a carrier-first and subframe second order in the downlink subframe set.

15. The non-transitory computer-readable medium according to claim 14 , wherein the sum field is carried on the downlink control channel.

16. The non-transitory computer-readable medium according to claim 13 , wherein the first indication field is in an uplink scheduling grant (UL_grant).

17. The non-transitory computer-readable medium according to claim 13 , wherein the instructions further cause the network device to:
send an index field on a downlink control channel,
wherein a value of the index field denotes an accumulative counting value of downlink subframes in the downlink subframe set, up to the first downlink subframe and a first carrier on which the first downlink subframe is located, first in increasing order of carrier number and then in increasing order of subframe number.

18. The non-transitory computer-readable medium according to claim 13 , wherein the downlink subframe set is a subset of a preconfigured downlink subframe set, and the preconfigured downlink subframe set is configured for the terminal and includes all downlink subframes on all carriers corresponding to the uplink subframe.
