Abstract

This disclosure provides an information processing method and apparatus, an information configuration method and apparatus, a terminal, and a network side device. The information processing method includes: determining a first resource allocation type configured for a multi-carrier scheduling; determining, according to the first resource allocation type, a frequency domain resource allocation (FDRA) type corresponding to an FDRA field in a first downlink control information (DCI), wherein the first DCI is used for scheduling physical uplink shared channels (PUSCHs) or physical downlink shared channels (PDSCHs) on multiple carriers.

First claim

1 . An information processing method, performed by a terminal, comprising:
determining a first resource allocation type configured for a multi-carrier scheduling; determining, according to the first resource allocation type, a frequency domain resource allocation (FDRA) type corresponding to an FDRA field in a first downlink control information (DCI); wherein the first DCI is used for scheduling physical uplink shared channels (PUSCHs) or physical downlink shared channels (PDSCHs) on multiple carriers.

2 . The method according to claim 1 , further comprising:
receiving a network indication sent by a network side device, wherein the network indication is used for instructing the terminal to determine the first resource allocation type used by the FDRA type corresponding to the FDRA field in the first DCI or a second resource allocation type used by the FDRA type corresponding to the FDRA field in the first DCI; the second resource allocation type is a resource allocation type configured for a single-carrier scheduling.

3 . The method according to claim 2 , wherein a resource allocation type for each of the multiple carriers is independently configured.

4 . The method according to claim 1 , wherein the determining the first resource allocation type configured for the multi-carrier scheduling comprises:
determining a second resource allocation type configured for each carrier through a single-carrier scheduling, wherein the each carrier is a carrier among the multiple carriers scheduled by the first DCI; in a case that the second resource allocation types are different, determining the first resource allocation type according to the second resource allocation type configured for each carrier; or, determining that the first resource allocation type is a resource allocation type 0; or, determining that the first resource allocation type is a resource allocation type 1.

5 . The method according to claim 4 , wherein the determining the first resource allocation type according to the second resource allocation type configured for each carrier comprises:
in response to the second resource allocation types including the resource allocation type 0, determining that the first resource allocation type is the resource allocation type 0; or, in response to the second resource allocation types not including the resource allocation type 0, determining that the first resource allocation type is the resource allocation type 1; or, in response to the second resource allocation types including the resource allocation type 1, determining that the first resource allocation type is the resource allocation type 1; or, in response to the second resource allocation types not including the resource allocation type 1, determining that the first resource allocation type is the resource allocation type 0; or, grouping the multiple carriers by the second resource allocation type, and determining that the first resource allocation type is the second resource allocation types corresponding to the groups.

6 . The method according to claim 1 , further comprising:
determining a resource block size for the multi-carrier scheduling and a reference bandwidth for the multi-carrier scheduling.

7 . The method according to claim 6 , wherein the determining the resource block size for the multi-carrier scheduling comprises:
determining the resource block size for the multi-carrier scheduling according to a resource block size configured by a network side device for the multi-carrier scheduling; or, determining the resource block size for the multi-carrier scheduling according to a resource block size configured for each carrier through a single-carrier scheduling; and/or, wherein the determining the reference bandwidth for the multi-carrier scheduling comprises:
determining the reference bandwidth for the multi-carrier scheduling according to a bandwidth configured by a network side device for the multi-carrier scheduling;
or,
determining that the reference bandwidth for the multi-carrier scheduling is a maximum bandwidth among the bandwidths configured for the multi carriers through the single-carrier scheduling.

9 . The method according to claim 1 , further comprising:
determining, by means of first information, a length value of the FDRA field in the first DCI; wherein the first information comprises one or more of the following:
the FDRA type corresponding to the FDRA field in the first DCI;
a resource block size for the multi-carrier scheduling;
a reference bandwidth for the multi-carrier scheduling;
a bandwidth corresponding to each carrier of the multi-carrier scheduling;
a size of a resource block group corresponding to each carrier of the multi-carrier scheduling.

10 . (canceled)

11 . The method according to claim 1 , further comprising:
sorting cell identification numbers corresponding to the multiple carriers according to a preset rule to obtain a plurality of sorted carriers.

12 - 15 . (canceled)

16 . An information configuration method, performed by a network side device, comprising:
