US 2025/0038902 A1 · MULTIPLE ACCESS (MA) SIGNATURE TRANSMISSIONS

Abstract

Multiple Access (MA) signature (MAS) features may be provided, for example, MAS pool definition and/or configuration may be provided. MAS indicator transmission may be provided. For example, independent indication through demodulation reference signal (DMRS) transmission and/or scheduling request (SR)-based transmission may be provided. Reliable MA detection may be provided. For example, multiple zone transmission and/or diversity may be provided. Non-orthogonal multiple-access (NOMA) transmission without MAS indication may be provided. Physical uplink control channel (PUCCH)-based NOMA indication may be provided. NOMA layer indicator (NLI) based NOMA indication may be provided.

Dependent claims

A wireless transmit/receive unit (WTRU) comprising:

a memory;
and
a processor configured to:
receive information indicating a set of resources associated with accessing a network, wherein the set of resources comprises a first set of time-frequency resources and a second set of time-frequency resources;
receive information indicating a multiple access signature (MAS) set;
select the first set of time-frequency resources or the second set of time-frequency resources, thereby obtaining a selected set of time-frequency resources;
determine, by the WTRU, a MAS from the MAS set, according to the WTRU's state of RRC connection, being one of:
connected, idle, and inactive mode, thereby obtaining a WTRU determined MAS;
and
perform a transmission in the selected set of time-frequency resources using the WTRU determined MAS.

7 more elements

A non-transitory computer readable medium having instructions stored thereon which, when executed by one or more processors, cause the one or more processors to perform a method implemented by a wireless transmit-receive unit (WTRU), the method comprising:

receiving information indicating a set of resources associated with accessing a network, wherein the set of resources comprises a first set of time-frequency resources and a second set of time-frequency resources;
receiving information indicating a multiple access signature (MAS) set;
selecting the first set of time-frequency resources or the second set of time-frequency resources, thereby obtaining a selected set of time-frequency resources;
determining, by the WTRU, a MAS from the MAS set, according to the WTRU's state of RRC connection, being one of:
connected, idle, and inactive mode, thereby obtaining a WTRU determined MAS;
and
performing a transmission in the selected set of time-frequency resources using the WTRU determined MAS.
