ENODEB and UE for dynamic cell on and off

摘要

Disclosed in some examples are methods, systems, and machine readable mediums which reuse existing LTE functionality to rapidly signal UEs on the availability of a LTE-U cell. Using these techniques the on/off operation can be in the order of a few milliseconds (ms). Several techniques are disclosed herein, including use of component carrier (CC) specific Discontinuous Reception (DRX) signaling, PDCCH signaling, DL assignment based signaling, Physical Hybrid Automatic Repeat Request Indicator Channel (PHICH) signaling, Beacon signaling, and the like.

主权项

1. An eNodeB, comprising:
hardware processing circuitry configured to:
provide a primary cell (P-Cell) on a primary frequency band during a first time slot;determine that a secondary frequency band is available for use by a secondary cell (S-Cell) during a second time slot, the second time slot being a subsequent time slot to the first time slot and the second frequency band being different than the primary frequency band; andtransmit an indication to a User Equipment (UE) during the first time slot, that the S-Cell is available for association after the first time slot and during the determined subsequent time slot, the subsequent time slot being associated with a timing boundary defining a beginning time and an end time of the subsequent time slot; and an S-Cell module configured to:
provide the S-Cell during the subsequent time slot, the S-Cell including a data channel.
