Abstract: Techniques are described for wireless communication. One method for wireless communication at a base station includes contending for access to a shared channel of a shared radio frequency spectrum band, and multiplexing first component carrier (CC) communication windows and second CC communication windows in the shared channel. A duration of orthogonal frequency domain multiplexed (OFDM) symbols of the first CC communication windows may be different from a duration of OFDM symbols of the second CC communication windows, and the multiplexing may occur on the shared channel upon winning contention for access to the shared channel. One method for wireless communication at a user equipment (UE) includes monitoring a shared channel of a shared radio frequency spectrum band for a first CC Listen Before Talk (LBT) frame, and receiving, in a second CC preamble, an indication of the first CC LBT frame.

Abstract: Systems, methods, and devices for inter-network service selection are described herein. Through the use of one or more of device identifiers and device classes, information including a randomization metric can be transmitted to networked devices indicating which devices and/or device classes are permitted or denied to access a given network service. Equipment seeking access may alter the selection based on this information. Equipment providing access may enforce access request based on this information. As an example, selection between eHRPD and LTE may be load balanced based on device class or identifiers.

Abstract: Methods, systems, and devices for wireless communication are described. A device may divide a packet data convergence protocol (PDCP) service data unit (SDU) into a set of PDCP segments based on a medium access control (MAC) layer transmission parameter, which may include a desired block size for MAC transmission or retransmission. The device may then append a PDCP header, generate one or more MAC protocol data unit (PDUs) and transmit the MAC PDUs. In some cases, information may be exchanged between the MAC layer and the PDCP layer to determine or signal the block size. A receiver may receive the MAC PDUs, identify multiple PDCP segment identifications (IDs) for PDCP PDUs that are generated from the received MAC PDUs, reorder the PDCP PDUs based on the PDCP segment IDs, and concatenate the PDCP PDUs before passing the data packets on to higher layers.

Abstract translation: 描述了用于无线通信的方法，系统和设备。 基于介质访问控制（MAC）层传输参数，设备可以将分组数据会聚协议（PDCP）业务数据单元（SDU）划分成一组PDCP分段，该媒体访问控制（MAC）层传输参数可以包括用于MAC传输或重传的期望的块大小。 然后，设备可以附加PDCP报头，生成一个或多个MAC协议数据单元（PDU）并发送MAC PDU。 在一些情况下，可以在MAC层和PDCP层之间交换信息以确定或指示块大小。 接收机可以接收MAC PDU，识别从接收到的MAC PDU生成的PDCP PDU的多个PDCP分段标识（ID），并根据PDCP分段ID对PDCP PDU进行重新排序，并且在将数据分组传送到PDCP PDU之前连接PDCP PDU 到更高层。

Abstract: Methods, systems, and devices are described for broadcast signal transmission using a number of nodes in an unlicensed spectrum. A set of nodes may be identified for use in transmission of a broadcast signal, with a first subset of the nodes transmitting the broadcast signal to deliver first content during a first time period, and with a second subset of the nodes transmitting the broadcast signal to deliver second content during a second time period. The first subset of nodes is different than the second subset of nodes. The set of nodes may thus form a single frequency network (SFN) that performs partial SFN operation during the first and second time periods.

Abstract: Systems, methods, and devices of the various embodiments enable evolved Multimedia Broadcast Multicast Service (“eMBMS”) network sharing, content sharing, and roaming. The various embodiments may enable Multimedia Broadcast Multicast Service (“MBMS”) service continuity across different public land mobile networks (“PLMNs”) by associating the same MBMS services providing identical content in different PLMNs with each other. In an embodiment, service discovery may be provisioned to a receiver device when or after the receiver device is attached to a PLMN. In an embodiment, content sharing across different PLMNs may be supported by a user service description indicating the different temporary mobile group identifiers (“TMGIs”) of the same service across different PLMNs. In another embodiment, content sharing across different PLMNs may be supported by a user service description indicating the same TMGI for the same service across different PLMNs. In an embodiment, MBMS keys may be shared across PLMNs.

Abstract: Access terminals are adapted to transmit a plurality of previously successful access probes to a network node, and determine an initial transmission power level for subsequent access attempts. The initial transmission power level can be determined based at least in part on one or more parameters associated with the plurality of previously successful access probes. An initial access probe of a subsequent access attempt can then be transmitted at the determined initial transmission power level. Network nodes that receive the one or more access probes from access terminals can send a message instructing the access terminals to employ a particular initial transmission power level for a subsequent access attempt. Other aspects, embodiments, and features are also included.

Abstract: Techniques are described for wireless communication. A first method includes performing a clear channel assessment (CCA) for a first node associated with a first operator in a deployment of operators over an unlicensed radio frequency spectrum band, and transmitting data over the unlicensed radio frequency spectrum band when the CCA is successful. The data may be transmitted by the first node in accordance with an agreement between the first operator and a second operator in the deployment of operators. A second method includes receiving over an unlicensed radio frequency spectrum band, at a user equipment (UE), a first transmission from a first node associated with a first operator in a deployment of operators. The first transmission may include data originating from a second operator in the deployment of operators.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a cyclic prefix duration for orthogonal frequency division multiple access symbols is determined. The cyclic prefix duration is calculated to reduce inter-symbol interference associated with a transmitter located at a distance that is more than 5 kilometers from one or more user equipment. Subcarrier spacing is determined and a symbol size for the symbols is determined. One or more of an enhanced Node B and a user equipment is configured with the cyclic prefix duration, the subcarrier spacing and the symbol size.
