  • Publication number: 20200053543
    Abstract: A user equipment (UE) can receive, from an eNodeB, a serving PLMN system information block (SIB)19 for a carrier frequency of a serving PLMN of the UE. The UE can acquire inter-frequency and inter-PLMN discovery system information acquisition assistance signaling information from the SIB19. The UE can process a non-serving PLMN SIB19 for one or more carrier frequencies of a non-serving PLMN using the inter-frequency and inter-PLMN discovery system information acquisition assistance signaling information. The UE can identify inter-frequency and inter-PLMN discovery announcement rate information and monitoring control configuration information for the one or more carrier frequencies of the non-serving PLMN to enable the UE to perform device-to-device (D2D) discovery with a UE in the non-serving PLMN according to the inter-frequency and inter-PLMN discovery announcement rate information and monitoring control configuration information.

  • Publication number: 20200029302
    Abstract: Systems and methods of reducing power consumption associated with paging or cDRX mode are described. A wake-up receiver (WUR) wakes up from an idle mode or cDRX state. Whether a wake-up signal (WUS) has been received by the WUR is determined. The WUS is a low-complexity signal that is less complicated than a PDCCH or PDSCH and is repeated multiple times at resource elements as indicated in a configuration from an eNB. If received, a baseband transceiver wakes up for reception of a PDCCH for the UE in a PO when the UE is in the idle mode or a PDSCH for the UE when the UE is in the cDRX state.

  • Publication number: 20190393992
    Abstract: An apparatus configured to be employed in a user equipment (UE) associated with a new radio (NR) system is disclosed. The apparatus comprises a processing circuit configured to determine an NR-physical uplink control channel (PUCCH) resource to be utilized by the UE, for a transmission of a hybrid automatic repeat request (HARQ)-acknowledge (ACK) feedback message to a gNodeB, wherein the determined NR-PUCCH resource comprises a HARQ-PUCCH resource. In some embodiments, the HARQ-ACK feedback message comprises a feedback message generated at the UE in response to processing a downlink (DL) data transmission signal comprising data received from the gNodeB. In some embodiments, the processing circuit is further configured to generate a transmission of the HARQ-ACK feedback message using the determined HARQ-PUCCH resource.

  • 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.

  • Patent number: 10517119
    Abstract: Embodiments described herein relate generally to techniques for device discovery for device-to-device (D2D) communications. A user equipment (UE) may receive a transmission probability (e.g., from an evolved Node B (eNB)) for transmission of a discovery medium access control (MAC) protocol data unit (PDU) for D2D communications. 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.

  • Publication number: 20190387578
    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.
