Abstract: A base station configures a Physical Downlink Control Channel (PDCCH) for transmission to one or more user equipments (UEs). The base station divides a component carrier (CC) bandwidth into a plurality of sub-bands, transmits a physical random access channel (PRACH) resource on at least one of the sub-bands and transmits a Type1-PDCCH CSS (Physical Downlink Control Channel Common Search Space) set on at least one of the sub-bands, wherein the Type1-PDCCH CSS set corresponds to the PRACH resource.

Abstract: A user equipment (UE) may transmit hybrid automatic repeat request (HARQ) feedback when part of a group of UEs. The UE receives a radio network temporary identifier (RNTI) associated with a group of UEs that includes the UE. The UE monitors for a signal from one of a cell on which the UE is currently camped or a cell to which the UE is currently connected that is scrambled by the RNTI and includes control information. The UE transmits HARQ feedback to the one of the currently camped cell or currently connected cell, the HARQ feedback associated with the signal and, when the signal is received, performs an operation in response to the control information.

Abstract: An evolved Node B (eNB) serves as a primary serving cell (PCell) providing a primary component carrier (PCC) in a licensed spectrum to a user equipment (UE) in a carrier aggregation (CA) scheme. A secondary component carrier (SCC) is provided in an unlicensed spectrum. The eNB monitors parameters of bandwidths in the unlicensed spectrum, when at least one of the parameters indicates a change in availability of a select one of the bandwidths, the eNB generates a control indicator defining the change in availability of the bandwidth and broadcasts the control indicator to the UE, wherein the control indicator affects a modification in a transceiver of the UE associated with the bandwidth.

Abstract: Apparatuses, systems, and methods for a wireless device to disable a HARQ feedback in either a semi-static way or in a dynamic way and to perform HARQ optimization. The wireless device may be configured to receive a first set and a second set of HARQ process numbers, where the first set and the second set of HARQ process numbers correspond to a first set and a second set of HARQ processes respectively, where each HARQ process in the first set of HARQ processes is configured to enable a HARQ feedback, and where each HARQ process in the second set of HARQ processes is configured to disable or enable a HARQ feedback. The wireless device may be configured to receive a grant configuration or a SPS, where the grant configuration or the SPS include a flag indicating whether a HARQ-based retransmission is disabled.
