Abstract
Various arrangements for transitioning the bandwidth allocation of a cellular network, such as at a base station, are presented. Bandwidth parts may be defined for communication with the cellular network, such as on a per-base station basis. At a given time, two of these bandwidth parts may be actively used for communication by different UE for communication with the base station. A determination to adjust a bandwidth allocation may be made. A series of transitions may be performed to migrate from the first two of these bandwidth parts to the second two of the bandwidth parts such that interference does not occur.
Claims20
A method for transitioning cellular network bandwidth allocation, the method comprising:
- defining, using a cellular network system, a first bandwidth part and a second bandwidth part to be used for communication with user equipment by a cellular network, wherein:
- the first bandwidth part and the second bandwidth part do not overlap;
- and
- the first bandwidth part has a different subcarrier spacing (SCS) than the second bandwidth part;
- determining to adjust a bandwidth allocation of the first bandwidth part and the second bandwidth part;
- defining, by the cellular network system, a third bandwidth part and a fourth bandwidth part to be used for communication with user equipment by the cellular network, wherein:
- the third bandwidth part and the fourth bandwidth part do not overlap;
- and
- the third bandwidth part has a different SCS than the fourth bandwidth part;
- performing a first transition of a first set of user equipment using the first bandwidth part to the third bandwidth part;
- and
- after the first transition, performing a second transition of a second set of user equipment using the second bandwidth part to the fourth bandwidth part.
A system comprising:
- a cellular network that communicates with a plurality of user equipment (UE), the cellular network being configured to:
- define a first bandwidth part and a second bandwidth part to be used for communication with user equipment by the cellular network, wherein:
- the first bandwidth part and the second bandwidth part do not overlap;
- and
- the first bandwidth part has a different subcarrier spacing (SCS) than the second bandwidth part;
- determine to adjust a bandwidth allocation of the first bandwidth part and the second bandwidth part;
- define a third bandwidth part and a fourth bandwidth part to be used for communication with user equipment by the cellular network, wherein:
- the third bandwidth part and the fourth bandwidth part do not overlap;
- the third bandwidth part has a different SCS than the fourth bandwidth part;
- the fourth bandwidth part has a wider bandwidth than the second bandwidth part;
- and
- the third bandwidth part has a narrower bandwidth than the first bandwidth part;
- cause a first transition of a first set of user equipment communicating with the cellular network using the first bandwidth part to the third bandwidth part;
- and
- cause a second transition of a second set of user equipment communicating with the cellular network using the second bandwidth part to the fourth bandwidth part after the first transition.
A non-transitory processor-readable medium, comprising processor-readable instructions configured to cause one or more processors of a cellular network to:
- define a first bandwidth part and a second bandwidth part to be used for communication with user equipment by the cellular network, wherein:
- the first bandwidth part and the second bandwidth part do not overlap;
- and
- the first bandwidth part has a different subcarrier spacing (SCS) than the second bandwidth part;
- determine to adjust a bandwidth allocation of the first bandwidth part and the second bandwidth part;
- define a third bandwidth part and a fourth bandwidth part to be used for communication with user equipment by the cellular network, wherein:
- the third bandwidth part and the fourth bandwidth part do not overlap;
- the third bandwidth part has a different SCS than the fourth bandwidth part;
- the fourth bandwidth part has a wider bandwidth than the second bandwidth part;
- and
- the third bandwidth part has a narrower bandwidth than the first bandwidth part;
- cause a first transition of a first set of user equipment communicating with the cellular network using the first bandwidth part to the third bandwidth part;
- and
- cause a second transition of a second set of user equipment communicating with the cellular network using the second bandwidth part to the fourth bandwidth part after the first transition.
