  • System and methods for support of frequency hopping for UEs with reduced bandwidth support
    Patent number: 10516517
    Abstract: An eNodeB (eNB), Machine Type Communications (MTC) user equipment (UE) and method using a physical uplink control channel (PUCCH) in a non-legacy PUCCH region are generally described. The UE may be in an enhanced coverage (EC) mode. The UE may receive higher layer signaling indicating physical resource blocks in the PUCCH region and offsets in a cell- or UE-specific manner on a per-slot basis or, when in EC mode, per-set of N subframes basis. The UE may receive a resource allocation for a PUCCH in a PUCCH region separate from a legacy PUCCH region and reserved for non-legacy UEs. The UE may transmit a frequency hopping PUCCH in the PUCCH region and use shortened PUCCH format to accommodate an extended retuning time by puncturing a first and/or last symbol of at least one slot. If retuning, the UE may drop a sounding reference signal transmission in the next subframe.

The UE may determine a pseudo-random number based on an identifier of the UE, information in the discovery MAC PDU, or information associated with a discovery period. The UE may compare the pseudo-random number with the transmission probability to determine whether to transmit the discovery MAC PDU in the discovery period. Another UE may also determine the pseudo-random number to determine whether the UE is to transmit the discovery MAC PDU in the discovery period. Other embodiments may be described and claimed.

    Abstract: A User Equipment (UE) and a Radio Access Network (RAN) node may be configured to use multiple Scheduling Request (SR) configurations. A SR configuration may indicate to radio resources to be used to communicate a SR to the RAN node. The RAN node may provide UE with information associating logical channels to SR configurations. When the UE has data to transmit to the RAN node, the UE may determine the logical channel corresponding to the data, determine the SR configuration corresponding to the logical channel, and communicate a SR to the RAN node in accordance with the SR configuration. Upon receiving the SR, the RAN node determine the SR configuration used to transmit the SR and in turn determine the logical channel for which the SR was transmitted. The RAN node may then transmit an Uplink (UL) grant for the logical channel to the UE.

DCI received on an MTC physical downlink control channel (MPDCCH) is decoded, the DCI indicating a narrowband (NB) index of a NB frequency resource and at least one PRB index for the PDSCH resource allocation. The NB frequency resource indicated by the NB index is shifted based on the activation of the flexible starting PRB for PDSCH resource allocation. PDSCH data received from the base station using the shifted NB frequency resource is decoded.
