Abstract
Some of the present embodiments provide a method for a random access procedure for a user equipment. The method receives a backoff indicator (BI). After receiving the BI, the method selects a configured contention-free random access (CFRA) preamble from one or more CFRA preambles that have been configured to the UE by a base station. The selected configured CFRA preamble corresponds to synchronization signal block (SSB) candidate detected by the UE. The method then transmits the selected CFRA preamble to the base station.
Claims5
A method for a random access (RA) procedure for a user equipment (UE), the method comprising:
- receiving, by the UE, a dedicated random access channel (RACH-ConfigDedicated) information element (IE) from a base station, the RACH-ConfigDedicated IE configures one or more RA preambles, wherein each of the one or more RA preambles corresponds to a high priority synchronization signal block (SSB) candidate;
- receiving, by the UE, a backoff indicator (BI);
- detecting, by the UE, a high priority SSB candidate that corresponds to an RA preamble from the configured one or more RA preambles;
- selecting, by the UE, the RA preamble corresponding to the detected high priority SSB candidate;
- and
- transmitting the selected RA preamble corresponding to the detected high priority SSB candidate to the base station.
A user equipment (UE) comprising:
- one or more non-transitory computer-readable media having computer-executable instructions embodied thereon;
- and
- at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to:
- receive a dedicated random access configuration (RACH-ConfigDedicated) information dement (IE) from a base station, the RACH-ConfigDedicated IE configures one or more RA preambles, wherein each of the one or more RA preambles corresponds to a high priority synchronization signal block (SSB) candidate;
- receive a backoff indicator (BI);
- detect a high priority SSB candidate that corresponds to an RA preamble from the configured one or more RA preambles;
- select the RA preamble corresponding to the detected high priority SSB candidate;
- and
- transmit the selected RA preamble corresponding to the detected high priority SSB candidate to the base station.
A method for a base station, the method comprising:
- configuring a dedicated random access channel (RACH-ConfigDedicated) information element (IE), the RACH-ConfigDedicated IE configuring one or more RA preambles, wherein each of the one or more RA preambles corresponds to a high priority synchronization signal block (SSB) candidate to a user equipment (UE);
- and
- transmitting a backoff indicator (BI) to the UE,
- wherein the UE detects a high priority SSB candidate that corresponds to an RA preamble from the configured one or more RA preambles, selects the RA preamble corresponding to the detected high priority SSB candidate, and transmits the selected RA preamble corresponding to the detected high priority SSB candidate to the base station.
A base station comprising:
- one or more non-transitory computer-readable media having computer-executable instructions embodied thereon;
- and
- at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to:
- configure a dedicated random access channel (RACH-ConfigDedicated) information element (IE), the RACH-ConfigDedicated IE configuring one or more RA preambles, wherein each of the one or more RA preambles corresponds to a high priority synchronization signal block (SSB) candidate;
- and
- transmit a backoff indicator to the UE,
- wherein the UE detects a high priority SSB candidate that corresponds to an RA preamble from the configured one or more RA preambles, selects the RA preamble corresponding to the detected high priority SSB candidate, and transmits the selected RA preamble corresponding to the detected high priority SSB candidate to the base station.
