Abstract
A method of initiating a Random Access communication between a 5G User Equipment (UE) and a 5G network node; the method comprising: if the current active UL-BWP of the UE has valid PRACH resources, the UE sending the Random Access Preamble on said current active UL-BWP; and if the current active UL-BWP of the UE has no valid PRACH resources, the UE sending the Random Access Preamble on the initial UL BWP; the method further comprising the UE monitoring the RAR in one of the initial DL-BWP and a default DL-BWP.
Claims20
A method of initiating a Random Access communication;
- the method comprising:
- based on a determination that a current active UpLink BandWidth Part (UL-BWP) of a User Equipment (UE) has valid Physical Random Access Channel (PRACH) resources, the UE sending a Random Access Preamble on the current active UL-BWP;
- and
- based on a determination that the current active UL-BWP of the UE has no valid PRACH resources, the UE sending the Random Access Preamble on an initial UL-BWP;
- and
- the method further comprising:
- the UE monitoring a Random Access Response (RAR) in an initial DownLink BandWidth Part (DL-BWP).
A method of initiating a Random Access communication;
- the method comprising:
- a User Equipment (UE) sending a Random Access Preamble on an initial UpLink BandWidth Part (UL-BWP);
- and
- the UE monitoring a Random Access Response (RAR) in an initial DownLink BandWidth Part (DL-BWP).
A user equipment, UE, comprising:
- a memory and a processor, the memory storing one or more computer programs that, when executed by the processor, cause the processor to execute operations of:
- sending a Random Access Preamble on a current active UpLink BandWidth Part (UL-BWP) when the current active UL-BWP of a User Equipment (UE) has valid Physical Random Access Channel (PRACH) resources;
- sending the Random Access Preamble on an initial UL-BWP when the current active UL-BWP of the UE has no valid PRACH resources;
- and
- monitoring a Random Access Response (RAR) in an initial DownLink BandWidth Part (DL-BWP).
A user equipment, UE, comprising:
- a memory and a processor, the memory storing one or more computer programs that, when executed by the processor, cause the processor to execute operations of:
- sending a Random Access Preamble on an initial UpLink BandWidth Part (UL-BWP);
- and
- monitoring a Random Access Response (RAR) in an initial DownLink BandWidth Part (DL-BWP).
