Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may utilize different beam configurations for different signal types, traffic demand, path loss, capabilities of the wireless device or other wireless devices in the system, and the like. The wireless device also may be capable of determining different duplexing modes, which may be utilized in addition to the different beam configurations. The duplexing mode may be based on received measurement reports (e.g., from one or more reference signals) or in some instances, the duplexing mode may be determined by another node (e.g., a core network node, a base station) and transmitted to the wireless device.

Abstract: Techniques are described for wireless communication. A first method may include performing a clear channel assessment (CCA) on an unlicensed radio frequency spectrum band; transmitting an indication of a time division duplexing (TDD) configuration over the unlicensed radio frequency spectrum band when the CCA is successful; and transmitting downlink data over the unlicensed radio frequency spectrum band in accordance with the TDD configuration when the CCA is successful. A second method may include performing a CCA on an unlicensed radio frequency spectrum band; dynamically determining, based at least in part on at least one grant to a user equipment (UE), and for a period following the CCA, a number of uplink subframes for communication over the unlicensed radio frequency spectrum band; and transmitting downlink data over the unlicensed radio frequency spectrum band in accordance with the timing of the number of uplink subframes when the CCA is successful.

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: Techniques are described for preempting resource allocations to one or more UEs in the event that delay sensitive data is received. A resource allocation of a number of symbols may be granted to a first user equipment (UE) for first associated data to be transmitted. Subsequently, data may be received for a second UE that is more delay sensitive than the first data. The resource allocation to the first UE may be preempted, and resources allocated to the second UE for the second data within a variable length transmission time interval (TTI) of the resource allocation to the first UE. UEs may monitor for preemption during transmissions to other UEs in order to receive new resource grants associated with the preempted resource grant. Whether a UE monitors transmissions for preemption may be determined based on a quality or service (QoS) of the UE.

Abstract: Methods and apparatuses for managing uplink scheduling for one or more user equipment served by a network entity in a wireless communications system are presented. For instance, an example method is presented that includes generating, by the network entity, an uplink bandwidth allocation map, the uplink bandwidth allocation map defining an uplink bandwidth allocation for at least one of the one or more user equipment for at least one of a plurality of uplink transmission window lengths. In addition, the example method includes transmitting the uplink bandwidth allocation map to at least one of the one or more user equipment.

Abstract: Certain aspects relate to methods and apparatus for latency reduction for UEs in a RRC connected mode. During contention-based uplink access by groups of UEs within a subframe, an eNB may decode the received uplink transmission based, at least in part, on the assigned group of resources assigned to the UE and used for transmission. Additional orthogonalization techniques such as reduced TTI size can be used to reduce collisions among different users performing contention-based transmissions. Furthermore, when the eNB fails to successfully decode the uplink transmission, the eNB may identify the UE that sent the uplink transmission based on a detected reference signal and may transmit an uplink assignment to the identified UE.

Abstract: A method and apparatus for uplink transmission by a user equipment (UE) includes receiving a first assignment for one or more beacon signals. The first assignment includes a first resource assignment and a first interlace assignment. The UE may determine that a size of a payload of an uplink transmission is less than a threshold. The UE may transmit the one or more beacon signals according to the first assignment in response to the determination. The one or more beacon signals increase bandwidth occupancy by the UE over a contention-based spectrum. Additionally, the UE may receive a second assignment for the payload of the uplink transmission. The second assignment includes a second resource assignment and a second interlace assignment. The UE may transmit the payload of the uplink transmission according to the second resource assignment on the second interlace assignment.

Abstract: Techniques are described for wireless communication. A first method includes generating uplink control information at a wireless device, and transmitting the uplink control information over an interlace of a component carrier of an unlicensed radio frequency spectrum band. The interlace includes a plurality of non-contiguous concurrent resource blocks in the unlicensed radio frequency spectrum band, and at least two resource blocks in the interlace include different portions of the uplink control information. A second method includes generating uplink control information at a wireless device, and transmitting the uplink control information over an uplink control channel of an unlicensed radio frequency spectrum band. Resources of the uplink control channel are divided into a plurality of discrete dimensions and the uplink control information of the wireless device is transmitted over a number of the discrete dimensions allocated to the uplink control information of the wireless device.

Abstract: Channel state information (CSI) feedback in long term evolution (LTE) and LTE-Advanced (LTE-A) networks including unlicensed spectrum is disclosed in which a base station obtains clear channel assessment (CCA) result information from neighboring base stations, either directly or by determining such results from measurement or reports from user equipment (UE) served by the base station. The base station may then generate control signaling based on the CCA result information for transmission to the one or more UEs served by the base station.
