Abstract
Disclosed are methods and apparatuses for small data transmission in random access. One embodiment of the subject application provides a method performed by a user equipment, including determining an association among a first random access channel (RACH) occasion (RO), a preamble, and a second RO, and receiving an random access response (RAR) in an Msg2 at least according to the second RO in response to transmitting the preamble in the first RO.
Claims20
An apparatus, comprising:
- a memory;
- and
- a processor coupled to the memory, the processor configured to cause the apparatus to:
- determine an association among a first random access channel (RACH) occasion (RO), a preamble, and a second RO, wherein to determine the association among the first RO, the preamble, and the second RO, the processor is configured to cause the apparatus to determine an association between the first RO and the second RO at least according to a synchronization signal block (SSB), wherein the first RO is configured for a first type of user equipment (UE), the second RO is configured for a second type of UE, the apparatus comprises a UE that belongs to the first type of UE, and the second RO is not earlier than the first RO in a time domain;
- and
- receive a random access response (RAR) in an Msg2 at least according to the second RO in response to transmitting the preamble in the first RO.

An apparatus, comprising:
- a memory;
- and
- a processor coupled to the memory, the processor configured to cause the apparatus to:
- determine an association among a first random access channel (RACH) occasion (RO), a preamble, and a second RO, wherein to determine the first RO for associating with the second RO, the processor is configured to cause the apparatus to determine the first RO for associating with the second RO at least according to a synchronization signal block (SSB), wherein the first RO is configured for a first type of UE, the second RO is configured for a second type of UE, the UE belongs to the second type of UE, and the second RO is not earlier than the first RO in a time domain;
- and
- transmit a random access response (RAR) in an Msg2 at least according to the second RO in response to receiving the preamble in the first RO from a user equipment (UE).
3 more elements
A method, comprising:
- determining, by a user equipment (UE), an association among a first random access channel (RACH) occasion (RO), a preamble, and a second RO, wherein determining the association among the first RO, the preamble, and the second RO further comprises determining an association between the first RO and the second RO at least according to a synchronization signal block (SSB), wherein the first RO is configured for a first type of UE, the second RO is configured for a second type of UE, the UE belongs to the first type of UE, and the second RO is not earlier than the first RO in a time domain;
- and
- receiving a random access response (RAR) in an Msg2 at least according to the second RO in response to transmitting the preamble in the first RO.
