Abstract
Disclosed are methods for a random access. One embodiment of the subject application provides a method performed by a user equipment, comprising sending a first message including a preamble; receiving a downlink control information (DCI) for scheduling a second message; determining a first resource, which is allocated based on a first resource unit; determining existence of a second resource, which is allocated based on a second resource unit, according to the DCI; and receiving the second message based on the determination. Related apparatuses are also disclosed.
Claims22
An apparatus, comprising:
- a memory;
- and
- a processor coupled to the memory, the processor configured to cause the apparatus to:
- send, by a user equipment (UE), a first message including a preamble;
- receive a downlink control information (DCI) for scheduling a second message;
- determine a first resource for the second message, which is allocated based on a first resource unit;
- and
- determine existence of a second resource for the second message, which is allocated based on a second resource unit, according to the DCI.
An apparatus, comprising:
- a memory;
- and
- a processor coupled to the memory, the processor configured to cause the apparatus to:
- receive at least one first message, wherein the at least one first message includes a preamble;
- determine an allocation of a second resource based on a second resource unit in addition to a first resource based on a first resource unit, according to the at least one first message based on a first resource unit;
- send a downlink control information (DCI) for scheduling at least one second message based on the determination;
- and
- send at least one second message in the determined resources.
