Abstract: Technology for a user equipment (UE) operable to identify downlink control channel candidates for receiving downlink control information is disclosed. The UE can decode a downlink control information (DCI) format received from an eNodeB. The DCI format can indicate a set of resource blocks (RBs) in one or more subframes allocated for reception or transmission of data or control information in a shortened transmission time interval (S-TTI). The UE can identify a subset of resource elements (REs) within the set of RBs in the one or more subframes. The subset of REs can correspond to shortened physical downlink control channel (S-PDCCH) candidates in the S-TTI of one or more subframes. The UE can attempt to decode the S-PDCCH candidates in the S-TTI of the one or more subframes. S-PDCCH candidates that are successfully decoded can cause the UE to identify the downlink control information.

Abstract: Latency reduction techniques for radio access networks are described. In various embodiments, a reduced transmission time interval (rTTI) may be implemented in order to reduce air interface latency in a radio access network. In some embodiments, an rTTI block may be defined, and some operations may be performed in rTTI block-wise fashion in order to reduce the marginal overhead associated with implementation of the rTTI. In various embodiments in which an rTTI is implemented, DM-RS granularity may be improved by use of techniques that enable data and reference signals to be multiplexed within a same OFDM symbol. In some embodiments, a current transmission time interval (TTI) may be maintained, and latency reduction may be achieved via the use of novel techniques for one or more of code block (CB) segmentation, uplink (UL) resource element (RE) mapping and HARQ cycle timing. Other embodiments are described and claimed.

Abstract: Technology for a user equipment (UE) to perform reduced transmission time interval (TTI) data transmission within a wireless communication network is disclosed. The UE can process a process, for transmission to an eNodeB, control information within a short transmission time interval (TTI) over a short resource block (RB) set within a short physical uplink control channel (S-PUCCH), wherein the short TTI is shorter in time than a TTI that has a duration of at least one (1) millisecond, and wherein the S-PUCCH is a subset of resources available for a short physical uplink shared channel (S-PUSCH) and the S-PUSCH is a subset of resources available for a legacy PUSCH transmission; and process, for transmission to the eNodeB, data within the short TTI over the short TTI RB set within the S-PUSCH.

Abstract: In embodiments, apparatuses, methods, and storage media may be described for distinguishing, by a user equipment (UE), a reference signal (RS) transmitted by a cell that may have a same identifier (ID) as another cell in a network. In embodiments, a muting pattern, a time offset, or a virtual cell identifier (VCID) may be used to generate an RS sequence or RS resource allocation.

Abstract: A hybrid automatic repeat request (HARQ) process enables a retransmission to be sent on a carrier (or medium, set of frequencies, band, etc.) different from the carrier on which the previous transmissions (initial transmission and/or retransmissions) were sent. An enhanced HARQ process can improve system performance by aiding user throughput, system throughput, and delay performance by making retransmissions possible even when the unlicensed band is not available (e.g., when occupied by other RATs or the same RAT deployed by another operator). For example, a transmitter sends a subpacket in an unlicensed band. The receiver feeds back a NACK to the transmitter due to the packet decoding failure. If the medium is not idle, the transmitter sends the retransmission in another band or another channel that can be either a licensed band/channel or another unlicensed band/channel. The retransmission can be sent in multiple licensed and/or unlicensed bands/channels at the same time.
