Abstract: Techniques are described for downlink coordinated multi-point (CoMP) procedures for access to a contention-based radio frequency spectrum band. A base station performs a contention procedure, such as a clear channel assessment (CCA) procedure, for access to the radio frequency spectrum band. The base station determines whether contention has been won for a time period, and communicates whether or not contention has been won to other base stations in a CoMP cooperating set. Based on the information exchanged between base stations in the CoMP cooperating set, coordinated communications is initiated to a UE with two or more of the base stations in the CoMP cooperating set.

Abstract: Management of shared transmission resources is disclosed for multiple radio access networks (RANs) sharing access to a finite number of transmission slots. Multiple permutations of slot assignments are configured in which each competing network is assigned a specific slot in each permutation. The sequence of permutations provides a fair distribution of spectrum access by the competing networks, such that in each permutation of the permutation sequence, networks assigned to lower priority slots may be assigned to higher priority slots in later permutations.

Abstract: Methods, systems, apparatuses, and devices are described for wireless communications. In one method, an opportunity may be identified for a first operator to perform a clear channel assessment (CCA) for a shared spectrum. The opportunity may be based on a priority of the first operator with respect to at least one other operator associated with the shared spectrum.

Abstract: Uplink waveforms for operating long term evolution (LTE) in an unlicensed band (i.e., long term evolution-unlicensed (LTE-U) communication) are disclosed. Carrier aggregation (CA) and standalone (SA) are disclosed. LTE on the licensed channel may provide both control and data, LTE on the unlicensed channel may provide data. Managing variable transmission time interval (TTI) continuous transmission is disclosed for transmission over multiple subframes of an unlicensed carrier in LTE-U. Listen-before-talk (LBT) requirements of unlicensed carriers provide for additional channel occupancy constraints when scheduling resources for multiple UEs for variable TTI continuous uplink transmissions over multiple subframes. A joint control channel is disclosed that provides control information for all of the potentially available subframes to be scheduled for the uplink transmissions. In addition to management of the variable TTI continuous transmissions, adjustments to uplink signal parameters are also disclosed that address the constraints due to the LBT requirements of unlicensed carriers.

Abstract: Certain aspects of the present disclosure relate to a technique for blindly decoding interfering cell Physical Downlink Control Channel (PDCCH) to acquire interfering cell Physical Downlink Shared Channel (PDSCH) transmission information. A UE may determine, for one or more aggregation levels, sets of CCEs that potentially include the PDCCH, based on available CCEs for each aggregation level and identify a set of decoding candidates based on the determination. Once the decoding candidates are decoded, the UE may perform an error correcting procedure on decoded candidates and prune out unlikely candidates. Likely decoded candidates may be further pruned based on comparison of CRC calculated using information bits only and possible Radio Network Temporary Identifiers (RNTIs). The UE may then interpret content of the PDCCH of the interfering cell based on surviving candidates. The UE may then use the interpreted PDCCH information to determine PDSCH information.

Abstract translation: 本公开的某些方面涉及用于盲目地解码干扰小区物理下行链路控制信道（PDCCH）以获取干扰小区物理下行链路共享信道（PDSCH）传输信息的技术。 基于每个聚合级别的可用CCE，UE可以针对一个或多个聚合级别确定潜在地包括PDCCH的CCE集合，并且基于该确定来识别一组解码候选。 一旦对解码候选进行解码，则UE可以对解码的候选进行纠错处理，并且修剪不太可能的候选者。 可以基于使用仅使用信息比特计算的CRC与可能的无线电网络临时标识符（RNTI）的比较来进一步修剪可能的解码候选。 然后，UE可以基于幸存的候选来解释干扰小区的PDCCH的内容。 然后，UE可以使用经解释的PDCCH信息来确定PDSCH信息。

Abstract: Methods and apparatus for paging comprise receiving data destined for a UE. The methods and apparatus further comprise determining a short identity for the UE relative to a longer global user equipment identity and identifying a MIB transmission based on a short identity. Moreover, the methods and apparatus comprise activating a bit within a slot of the MIB transmission to indicate that the user equipment listen for a page in order to receive the data and broadcasting the MIB. In other aspects, methods and apparatus for receiving a page comprise entering an idle state while camped on a cell. The methods and apparatus further comprise waking up from the idle state to monitor a slot of a MIB for a paging indication. Moreover, the methods and apparatus comprise recognizing the paging indication in the monitored slot of the MIB, determining a paging window based on correlation information in a SIB and waking up to listen for a page during the paging window.

Abstract: A selection process is disclosed for a user equipment (UE) to select between a WAN and a WLAN. Instead of defaulting to select one or the other networks, as long as the connection is available, a better load balancing and maximization of the system capacity may be achieved when the UE selects the network according to a priority order between the WAN/WLAN. The priority order takes into account various network metrics, such as loading, channel conditions, bandwidth, and service requirements.

Abstract: Signaling and procedural considerations are disclosed for uplink multiflow operations in user equipment configured for carrier aggregation. Advanced wireless networks may take advantage of unused capacity of neighboring cells by configuring network nodes and UEs to both receive on the downlink and transmit on the uplink to multiple cells or network nodes. Implementing multiflow on UE for the uplink transmission process may cause issues in various channels, signaling, and procedural operations that may be addressed through data and control signaling the techniques disclosed herein.
