摘要:
Embodiments of the present disclosure include methods, apparatuses, and instructions for receiving at a user equipment (UE) of a third generation partnership project (3GPP) network an offset value selected from a plurality of offset values in downlink control information. The UE also receives one or more enhanced control channel elements (eCCEs) of an enhanced physical downlink control channel (ePDCCH). The UE may then determine an allocation of an uplink resource for a transmission on a physical uplink control channel (PUCCH) based at least in part on the index of a first eCCE and the offset value.

Embodiments of wireless communication devices and methods for device discovery is generally described herein. Some of these embodiments describe an apparatus having processing circuitry arranged to configure a single-tone discovery signal for transmission in a symbol in a transmission opportunity based on an assignment pattern. The assignment pattern may define frequency positions, for a set of transmission opportunities, at which the apparatus shall transmit discovery signals in the corresponding transmission opportunity. The apparatus may have physical layer circuitry arranged to transmit the single-tone discovery signal in the corresponding transmission opportunity. Other methods and apparatuses are also described.

Technology for blind decoding downlink control information (DCI) from an enhanced physical downlink control channel (EPDCCH) is disclosed. In an example, a user equipment (UE) can include a processor configured to: Recursively attempt to decode the DCI from enhanced control channel elements (ECCE) of the EPDCCH from physical resource block (PRB) region candidates in a PRB set using a selected set of enhanced resource element group (EREG) index maps for the ECCE until the DCI is successfully decoded; and decode the DCI with an EREG index map associated with a same aggregation level used to encode the DCI. Each EREG index map can be configured for a different aggregation level (AL).

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.
摘要:
Sub-band allocation techniques for reduced-bandwidth machine-type communication (MTC) devices are described. In one embodiment, for example, user equipment (UE) may comprise logic, at least a portion of which is in hardware, the logic to identify a machine-type communication (MTC) sub-band allocation based on received MTC sub-band allocation information, the MTC sub-band allocation to comprise an allocation of a plurality of subcarriers to an MTC sub-band of a system bandwidth of a serving cell of the UE, the MTC sub-band allocation to define at least one MTC direct current (DC) subcarrier among the plurality of subcarriers, and a radio interface to receive a transmission via the MTC sub-band according to the MTC sub-band allocation. Other embodiments are described and claimed.
摘要:
An eNodeB (eNB), user equipment (UE) and method for operating in enhanced coverage (EC) modes are generally described. The UE may determine whether or not a physical uplink control channel (PUCCH) signal and an uplink signal allocated to different resources in a particular subframe overlap. The uplink signal may comprise another PUCCH signal or a physical uplink shared channel (PUSCH) signal. The PUCCH signals may comprise a scheduling request or acknowledgement response/retransmission request. The UE may select one of the overlapping signals and transmit the selected signal on a resource allocated to the other signal instead of on a resource allocated to the one of the overlapping signals. The other signal may or may not be transmitted dependent on whether it is a PUCCH or PUSCH signal.

Embodiments of the present disclosure describe apparatuses and methods for signal designs for device-to-device (D2D) subframes. Various embodiments may include a UE with a radio transceiver to communicate with another UE via D2D communications. The UE may further include processing circuitry to generate a cyclic prefix (CP) for a first or second symbol of a D2D subframe at an orthogonal frequency division multiplexing (OFDM) resource block or a single-carrier frequency-division multiple access (SC-FDMA) resource block. Other embodiments may be described and/or claimed.
摘要:
Embodiments described herein include user equipment (UE), evolved node B (eNB), methods, and systems for narrowband Internet-of-Things (IoT) communications. Some embodiments particularly relate to control channel communications between UE and eNB in narrowband IoT communications. In one embodiment, a UE blind decodes a first control transmission from an evolved node B (eNB) by processing a first physical resource block comprising all subcarriers of the transmission bandwidth and all orthogonal frequency division multiplexed symbols of a first subframe to determine the first control transmission. In various further embodiments, various resource groupings of resource elements are used as part of the control communications.
摘要:
An enhanced NodeB (eNB), user equipment (UE) and method of Channel State Information (CSI) measurement and reporting using reduced bandwidth are generally described herein. The UE is preconfigured with a resource configuration information or the configuration information is transmitted to the UE from the eNB. The configuration information indicates a narrowband region on which to monitor for and receive physical downlink control and data channels and perform measurements for CSI computation. The region has a reduced bandwidth that is supported by the UE and is free from subbands outside of the region. The UE takes measurements of downlink transmissions using the assigned resources. The measurements are limited to subbands included within the region. The UE calculates the CSI based on an unrestricted time interval within subframes of the region and a restricted frequency interval free from physical resource blocks outside the region. The UE reports a region-specific wideband CSI that includes at least a region-specific wideband Channel Quality Indicator to the eNB.
