Abstract: Technologies described herein provide mechanisms and formats to accomplish short transmission time interval (S-TTI) length in wireless communication systems. In one implementation, logic is to: identify S-TTI length based on which to allocate resources of a channel of a radio access network cell; based on the S-TTI length, determine a low latency resource block (LLRB) size according to which to allocate resources of the channel and a demodulation reference signal (DMRS) pattern according to which to transmit DMRSs to user equipment (UE) via the channel; and generate the DMRSs for transmission to the UE using resources identified based on the DMRS pattern. Other embodiments are described and claimed.

Abstract: An eNodeB (eNB), user equipment (UE) and method of providing a dynamically determined guard interval (GI) sequence are generally described. Uplink and downlink TDD subframes may each contain a block having a symbol and a GI sequence. The GI sequences may differ or be the same between the different subframes and the GI sequences may depend on an estimation of channel delay spread, a cell identifier (ID) of a cell to which the UE is configured to communicate, and a UE ID. The uplink or downlink subframe may comprise a guard time. A last block of the downlink subframe or first block of the uplink subframe may contain the GI sequence and the guard time and a first block of the uplink subframe or last block of the downlink subframe respectively may contain an additional GI sequence to maintain cyclicity.

Abstract: Embodiments of an Evolved Node-B (eNB) and methods for HARQ transmission are disclosed herein. The eNB may transmit, to a reduced-latency User Equipment (UE), an initial HARQ block and a diversity HARQ block for a reduced-latency data block. A sub-frame spacing between the transmissions of the HARQ blocks may be less than a sub-frame spacing used for transmissions of HARQ blocks to UEs not operating as reduced-latency UEs. The HARQ blocks for the reduced-latency data block may be transmitted in a reduced-latency region of time and frequency resources reserved for HARQ processes with reduced-latency UEs. In addition, HARQ blocks may be transmitted in time and frequency resources exclusive of the reduced-latency region to other UEs not operating as reduced-latency UEs.

Abstract: Described is an apparatus of an Evolved Node-B (eNB) operable to communicate with a User Equipment (UE) on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to establish a time-domain bundling window spanning an initial Short Transmission Time Interval (S-TTI) and one or more subsequent S-TTIs. The second circuitry may be operable to generate a first Downlink Control Information (DCI) carried by a first Downlink (DL) control region of the time-domain bundling window, and to generate a second DCI carried by a second DL control region of the time-domain bundling window. The third circuitry may be operable to determine resources scheduled for data transmission in one of the subsequent S- TTIs based upon scheduling information in the first DCI and scheduling information in the second DCI.

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: A user equipment (UE) can reserve shared spectrum between two wireless protocols upon the request from a tower. For example, an enhanced node B (eNB or eNodeB) transmits a message to associated UEs including a set of candidate UEs, a length of time to reserve, and a frequency band to use. UEs perform medium sensing on the specified spectrum if a UE finds its identifier in the set of candidate UEs. Candidate UEs transmit a clear to send (CTS) message with channel reservation information if the medium is idle. A result of the success or failure of the CTS transmission attempt is sent back to the eNB. Upon receiving the feedback information from the UEs, the eNB starts sending data to those UEs that sent the positive feedback on the channel reservation.

Abstract: Described are mechanisms for eNB support of DRS in LAA, in which DRS is transmitted at one or more DRS occasions within a DMTC window, subject to LBT. In some embodiments, an eNB may include hardware processing circuitry comprising an antenna port, a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to determine a DMTC window of a wireless communication channel. The second circuitry may be operable to initiate one or more CCA checks through an antenna coupled to the antenna port prior to a DRS occasion within a DMTC time window. The third circuitry may be operable to initiate a DRS transmission through the antenna within the DMTC window upon a CCA check of the set of one or more CCA checks sensing that the wireless communication channel is idle. Also described are mechanisms for proactive support of DRS in LAA.

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.
