Abstract
Systems, methods and apparatus are disclosed for user equipment and/or network nodes. An example method performed by a network node includes providing a shared resource to a plurality of user equipments (UEs) that are active on a bandwidth part (BWP). The network node receives a Scheduling Request (SR) on the shared resource of the BWP, and responsive to the SR, assigns one or more grants to one or more of the plurality of UEs that are provided with the shared resource. The network node monitors another resource, for a time window after the assigning of the one or more grants, and after receiving a transmission on the monitored resource from a UE, provides the UE with a dedicated resource on the BWP.
Claims20
A method performed by a network node in a radio access network (RAN), the method comprising:
- providing a shared physical uplink control channel (PUCCH) resource to a plurality of user equipments (UEs) that are active on a bandwidth part (BWP);
- receiving a scheduling request (SR) on the shared PUCCH resource of the BWP;
- responsive to the SR, assigning one or more grants to one or more of the plurality of UEs that are provided with the shared PUCCH;
- monitoring, for a time window after assigning the one or more grants, a physical uplink shared channel (PUSCH) resource;
- and
- after receiving a transmission on the monitored PUSCH resource from a UE of the plurality of UEs, providing the UE with a dedicated PUCCH resource on the BWP.
A method performed by a user equipment, UE, comprising:
- receiving, from a network node, an assignment of a shared physical uplink control channel (PUCCH) resource on a bandwidth part (BWP), wherein the shared PUCCH resource is shared between a plurality of UEs;
- providing a scheduling request (SR) on the shared PUCCH resource of the BWP;
- receiving a grant corresponding to the SR;
- providing, using the grant, a physical uplink shared channel (PUSCH) transmission on a monitored PUSCH resource;
- and
- after providing the PUSCH transmission, receiving a configuration corresponding to a dedicated PUCCH resource on the BWP.
A system comprising:
- a network node;
- and
- a user equipment, UE, communicatively coupled to the network node, the user equipment configured to perform operations comprising:
- receiving, from the network node, an assignment of a shared physical uplink control channel (PUCCH) resource on a bandwidth part (BWP), wherein the shared PUCCH resource is shared between a plurality of UEs;
- providing a scheduling request (SR) on the shared PUCCH resource of the BWP;
- receiving a grant corresponding to the SR;
- providing, using the grant, a physical uplink shared channel (PUSCH) transmission on a monitored PUSCH resource;
- and
- after providing the PUSCH transmission, receiving a configuration corresponding to a dedicated PUCCH resource on the BWP.
