Abstract:
In embodiments, an evolved Node B (eNB) of a wireless communication network may configure an enhanced physical downlink control channel (EPDCCH) physical resource block (PRB) set for a user equipment (UE). The EPDCCH-PRB set may include a plurality of PRB-pairs. The EPDCCH-PRB set may further include a plurality of enhanced resource element groups (EREGs) organized into localized enhanced control channel elements (ECCEs) having EREGs of the same PRB-pair and distributed ECCEs having EREGs of different PRB-pairs. In some embodiments, the eNB may determine a set of distributed EPDCCH candidates for the UE from the EPDCCH-PRB set, wherein the individual distributed EPDCCH candidates include one or more of the distributed ECCEs, and wherein the set of distributed EPDCCH candidates includes at least one EREG from each of the plurality of localized ECCEs. Other embodiments may be described and claimed.
Abstract:
Apparatus, systems, and methods to implement DRS-based power control in communication systems are described. In one example, a network entity comprises processing circuitry to configure at least one discovery reference signal (DRS) for path loss measurement, determine a discovery reference signal power setting and transmit the discovery reference signal (DRS) via a wireless communication link. Other examples are also disclosed and claimed.
Abstract:
Mobile communication devices, such as user equipment (UE) using 3GPP-LTE or LTE Advanced, may communicate directly with another UE through a system called Device-to-Device (D2D) communication. The establishment of a D2D communication session may involve having one of the UEs trigger the signaling procedures. In particular, a D2D resource re-allocation method may be used to optimize the D2D communication resource utilization efficiency in a dynamic manner, which is fully controlled by one of the D2D pair (termed the master UE or M-UE). The M-UE may be arranged to re-allocate resources based on the buffer status report (BSR) of the UEs in the D2D communication session. The M-UE may be further arranged to dynamically change the configuration of the transmission window based on characteristics of the D2D communication session.

Abstract:
Technology to provide physical uplink control channel (PUCCH) resource allocation in time division duplex (TDD) for a hybrid automatic retransmission request-acknowledge (HARQ-ACK) transmission in a subframe n is disclosed. In an example, a user equipment (UE) can include first circuitry configured to detect a downlink control channel within a prior specified subframe that is received in time before the subframe n. The UE can include second circuitry configured to: determine that the downlink control channel detected within the prior specified subframe is one of a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH); and determine one of a legacy PUCCH resource for the HARQ-ACK transmission when the downlink control channel detected within the prior specified subframe is the PDCCH or an enhanced PUCCH resource for the HARQ-ACK transmission when the downlink control channel detected within the prior specified subframe is the EPDCCH.
Abstract:
Embodiments for providing fast modulation and coding scheme adaptation for LTE regardless of transmission using single-user multiple-input and multiple-output (SU-MIMO) or multiple-user multiple-input and multiple-output are generally described herein. In some embodiments, channel state information reference signals are sent to user equipment by a node. First channel quality indication feedback based on the channel state information reference signals is received from the user equipment. Physical downlink shared channel data and demodulation reference signals are transmitted using a first modulation and coding scheme based on the first channel quality indication feedback. Second channel quality indication feedback based on measurements performed by the user equipment on the demodulation reference signals is received by a node. Physical downlink shared channel data is transmitted using a second modulation and coding scheme based on the second channel quality indication feedback.
