Abstract: A wireless communication system is presented for future scheduling of secondary component carrier(s) (SCC) during carrier aggregation in LTE wireless communications. A primary component carrier in a first subframe can be used to indicate at what future subframe SCC data may exist for the mobile device (e.g., UE, etc.). The UE can then leave off all SCC receive circuitry until the future subframe, when it can turn on all needed SCC receive circuitry to receive the SCC data. After receiving the SCC data, the UE can again power off the SCC receive circuitry.

Abstract: QoS based uplink data buffering while TTI bundling is enabled by a wireless user equipment (UE) device. The UE may establish a packet-switched connection with a network via a wireless link. The UE may receive, at a media access control (MAC) layer, an indication to enable TTI bundling. The UE may selectively buffer uplink data at an application layer based on the indication to enable TTI bundling. The uplink data may be buffered selectively based on Quality of Service (QoS) considerations. Uplink transmissions may subsequently be performed using TTI bundling.
Abstract translation: 基于QoS的上行链路数据缓冲，而TTI绑定由无线用户设备（UE）设备启用。 UE可以经由无线链路与网络建立分组交换连接。 在媒体接入控制（MAC）层，UE可以接收启用TTI绑定的指示。 基于用于启用TTI绑定的指示，UE可以选择性地缓冲应用层上的上行链路数据。 可以基于服务质量（QoS）考虑来选择性地缓冲上行链路数据。 随后可以使用TTI捆绑来执行上行链路传输。

Abstract: A method for managing a QoE for a UE in a communications network is provided. The method includes determining, based at least on data received in a communications session, one or more parameters affecting the QoE. The method includes determining weights corresponding to the one or more parameters. The method includes computing an expected QoE for the UE based on the determined weights corresponding to the one or more parameters. The method includes determining that the expected QoE satisfies a threshold. The method includes transmitting, to one or more network nodes in the communications network, the determined weights corresponding to the one or more parameters. The method also includes adjusting the communications session at the UE.

Abstract: A user equipment (UE) device may perform random access to a base station in the context where propagation delay between the base station and the UE device is large. The UE device randomly selects a random access preamble from an available set of preambles. The UE device selects a time slot for transmission of the random access preamble based on a configured correspondence between allowable time slots and subsets of the available set. The UE device transmits the random access preamble to a base station in the selected time slot, with timing advance to compensate for a common delay. Thus, the base station, knowing the configured correspondence, is able to determine the time slot in which the random access preamble was transmitted. The UE device receives a random access response that has been addressed with a Random Access Radio Network Temporary Identifier (RA-RNTI).

Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A base station (BS) may receive from a user equipment (UE) a first buffer status report (BSR) indicating an amount of uplink data buffered by the UE for transmission to the BS, and may subsequently receive a first BSR update message indicating that an additional amount of uplink data has been buffered by the UE subsequent to transmission of the first BSR. The first BSR update message may be received prior to expiration of a timer authorizing transmission of a second BSR following the first BSR. In response, the BS may allocate resources for transmission to the UE, based on the first BSR and the first BSR update message. The BS may provide an uplink grant identifying the allocated resources.

Abstract: This disclosure relates to providing a reservation signal for cellular communication in unlicensed spectrum. A cellular base station may perform a listen-before-talk procedure on an unlicensed frequency channel. The cellular base station may transmit a reservation signal on the unlicensed frequency channel after successfully performing the listen-before-talk procedure. The cellular base station may perform carrier sensing on the unlicensed frequency channel at least once during the duration of the reservation signal. The cellular base station may perform cellular communication on the unlicensed frequency channel after ceasing transmitting the reservation signal.

Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A base station may receive from user equipment device (UE) a random access initiation message, having a characteristic that is configured to indicate to the base station a requested size of a subsequent uplink grant to be provided by the base station for transmission of uplink data by the UE. For example, the characteristic may include a predetermined preamble included in the random access initiation message, such that a requested grant size is indicated by which preamble the UE selects from a plurality of possible preambles. As another example, the characteristic may include which RACH occasion is selected by the UE to transmit the random access initiation message. In response, the base station may allocate resources for use by the UE based on the characteristic.

The uplink grant may have a size based on the first BSR and the first BSR update message.
