Resource allocation method and apparatus, and resource determining method and apparatus

An apparatus comprising:

• a memory storing program instructions;
• and
• a processor coupled to the memory, wherein the program instructions, when executed by the processor, cause the apparatus to:
• obtain a resource block allocation field in downlink control information, wherein a size of the resource block allocation field is
• ⌈
• log
• 2
• ⁢
• ⌊
• N
• RB
• UL
• 6
• ⌋
• ⌉
• +
• 5
• ⁢
• ⁢
• bits
• ,
• and NRBUL is an uplink bandwidth configuration;
• in response to a value indicated by five least significant bits of the resource block allocation field being less than or equal to 20, determine an indicated narrowband according to
• ⌈
• log
• 2
• ⁢
• ⌊
• N
• RB
• UL
• 6
• ⌋
• ⌉
• most significant bits of the resource block allocation field, determine at least one resource block allocated to a terminal device within the indicated narrowband by using an uplink resource allocation type 0 according to the five least significant bits of the resource block allocation field, and send a physical uplink shared channel (PUSCH) on the allocated at least one resource block;
• and
• in response to a value indicated by the five least significant bits of the resource block allocation field being greater than 20, determine a first resource indication value indicated by the resource block allocation field, determine, based on the first resource indication value, a quantity of resource block groups allocated to a terminal device and an index of a starting resource block group allocated to the terminal device, wherein the quantity of allocated resource block groups is greater than or equal to 3 and is less than or equal to 8, and one resource block group comprises three resource blocks, and determine resource blocks allocated to the terminal device according to the quantity of resource block groups and the index of the starting resource block group, and send a PUSCH on the allocated resource blocks.
