Abstract
Various solutions for enhancements on random access channel (RACH)-less handover are described. An apparatus may receive a handover (HO) command for a RACH-less handover from a first network node. The HO command may include one or more parameters specific for the RACH-less handover. The apparatus may perform an initial uplink (UL) transmission of the RACH-less handover to a second network node based on the one or more parameters. Then, the apparatus may monitor a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH) for a completion indication of the RACH-less handover.
Claims20
A method, comprising:
- receiving, by a processor of an apparatus, a handover (HO) command for a random access channel (RACH)-less handover from a first network node, wherein the HO command comprises one or more parameters specific for the RACH-less handover;
- performing, by the processor, an initial uplink (UL) transmission of the RACH-less handover to a second network node based on the one or more parameters;
- and
- monitoring, by the processor, a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH) for a completion indication of the RACH-less handover.
An apparatus, comprising:
- a transceiver which, during operation, wirelessly communicates with a first network node or a second network node;
- and
- a processor communicatively coupled to the transceiver such that, during operation, the processor performs operations comprising:
- receiving, via the transceiver, a handover (HO) command for a random access channel (RACH)-less handover from the first network node, wherein the HO command comprises one or more parameters specific for the RACH-less handover;
- receiving, via the transceiver, a downlink control information (DCI) from the network node, wherein the DCI indicates a scheduling of multiple transport blocks (TBs) associated with the HARQ processes in a narrowband physical downlink shared channel (NPDSCH);
- performing, via the transceiver, an initial uplink (UL) transmission of the RACH-less handover to the second network node based on the one or more parameters;
- and
- monitoring, via the transceiver, a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH) for a completion indication of the RACH-less handover.
