Claim 10:
11. A network device, comprising a memory, a processor, and a program stored in the memory and executable by the processor, wherein the program, when being executed by the processor, performs the following steps:
transmitting target resource indication information to a user equipment based on a pre-defined mapping relationship;
wherein the target resource indication information is used to determine a physical random access channel transmission occasion (RO) resource, the target resource indication information comprises at least one of: a physical random access channel (PRACH) mask index or an RO resource index, and the pre-defined mapping relationship comprises a correspondence between a value range of the target resource indication information and the RO resource,
wherein the pre-defined mapping relationship comprises one or more of the following relationships:
in a case that the value range of the target resource indication information is in a first preset interval, the RO resource corresponding to the value range comprises: all configured RO resources within a preset time interval;
in a case that the value range of the target resource indication information is in a second preset interval, the RO resource corresponding to the value range comprises: an RO resource associated with a preset associated object, in an odd-numbered RO resource group;
in a case that the value range of the target resource indication information is in a third preset interval, the RO resource corresponding to the value range comprises: an RO resource associated with a preset associated object, in an even-numbered RO resource group;
in a case that the value range of the target resource indication information is in a fourth preset interval, the RO resource corresponding to the value range comprises: an RO resource that is associated with a preset associated object and has an odd index number, in an odd-numbered RO resource group; and an RO resource that is associated with a preset associated object and has an even index number, in an even-numbered RO resource group;
in a case that the value range of the target resource indication information is in a fifth preset interval, the RO resource corresponding to the value range comprises: all RO resources associated with a preset associated object, in an ith subgroup of all RO resource groups, wherein i is determined according to a value of the target resource indication information, subgroups are obtained by equally dividing all the RO resource groups, and i is an integer greater than zero and less than or equal to a total amount of the subgroups;
in a case that the value range of the target resource indication information is in a sixth preset interval, the RO resource corresponding to the value range comprises: RO resources in a jth subgroup among all RO resources associated with a preset associated object, from all RO resource groups, wherein j is determined according to a value of the target resource indication information, subgroups are obtained by equally dividing all the RO resources associated with the preset associated object, and j is an integer greater than zero and less than or equal to a total amount of the subgroups;
in a case that the value range of the target resource indication information is in a seventh preset interval, the RO resource corresponding to the value range comprises: RO resources associated with a preset associated object, in a preset number of consecutive RO resource groups starting from a RO resource group having a preset serial number;
in a case that the value range of the target resource indication information is in an eighth preset interval, the RO resource corresponding to the value range comprises: all RO resources associated with a preset associated object, in a RO resource group having a preset serial number, wherein the preset serial number is determined according to a value of the target resource indication information;
in a case that the value range of the target resource indication information is in a ninth preset interval, the RO resource corresponding to the value range comprises: an RO resource that is associated with a preset associated object and has a preset index number, in all RO resource groups;
in a case that the value range of the target resource indication information is in a tenth preset interval, the RO resource corresponding to the value range comprises: an RO resource that is associated with a preset associated object and has a preset index number, in an odd-number RO resource group;
in a case that the value range of the target resource indication information is in an eleventh preset interval, the RO resource corresponding to the value range comprises: an RO resource that is associated with a preset associated object and has a preset index number, in an even-number RO resource group;
in a case that the value range of the target resource indication information is in a twelfth preset interval, the RO resource corresponding to the value range comprises: an RO resource that is associated with a preset associated object and has a preset index number, in a kth subgroup of all RO resource groups, wherein k is determined according to a value of the target resource indication information, subgroups are obtained by equally dividing all resource groups, and k is an integer greater than zero and less than or equal to a total amount of the subgroups;
in a case that the value range of the target resource indication information is in a thirteenth preset interval, the RO resource corresponding to the value range comprises: an RO resource that is associated with a preset associated object and has a preset index number, in an RO resource group having a preset serial number, wherein the preset serial number is determined according to a value of the target resource indication information; or,
in a case that the value range of the target resource indication information is in a fourteenth preset interval, the RO resource corresponding to the value range comprises: an RO resource that is associated with a preset associated object and has a preset index number, in a preset number of consecutive RO resource groups starting from a RO resource group having a preset serial number.
