Abstract:
Embodiments of a UE and methods for D2D communication are generally described herein. The UE may transmit, as part of an in-network communication session, a D2D discovery status message. The D2D discovery status message may indicate an initiation or termination of a D2D discovery operation at the UE and may indicate if the UE is announcing or monitoring as part of the D2D discovery operation. The D2D discovery operation may be at least partly for configuring a D2D communication session between the UE and one or more other UEs. The UE may transmit, as part of the D2D discovery operation, a D2D discovery signal for reception at one or more other UEs. The UE may transmit and receive D2D packets over a direct link to a second UE as part of the D2D communication session.
Abstract:
Disclosed embodiments include an end-to-end UE and eNB HARQ protocol design for various TDD-FDD joint operation wireless network configurations. Designs for timing of HARQ feedback in response to PDSCH and PUSCH transmissions (or simply, PDSCH and PUSCH) include both HARQ feedback from a UE, and HARQ feedback from an eNB. The PUSCH HARQ timeline embodiments also include both self-scheduling and cross-carrier scheduling scenarios for PUSCH transmissions. In addition, designs for the cross-carrier scheduling scenarios contemplate an FDD scheduling cell or a TDD scheduling cell.
Abstract:
In one exemplary embodiment of the invention, a method including: determining whether first allocation information has been transmitted from a first device towards a second device in a wireless communication system (901 ); and transmitting a message including transmittal information and second allocation information from the first device towards the second device, wherein the transmittal information corresponds to the determined transmittal of the first allocation information (902). In another exemplary embodiment of the invention, a method including: detecting whether a first signal is received on a dedicated resource of a wireless communication system (501); detecting whether a second signal is received on a shared resource of the wireless communication system (502); and determining, based on a detection outcome for the first signal and a detection outcome for the second signal, whether at least one allocation has failed (503).
Abstract:
Systems and methods are disclosed that facilitate dynamically de-assigning resources and communication channels for transmitting messages indicative of resource de-assigning. Systems and method for generating and interpreting de-assignment messages are also provided.
Abstract:
The invention provides a networked sports training system comprising a plurality of local training stations and a central station with which each local training station can communicate via a telecommunications network. Each of the local training stations comprises a stationary training device, one or more sensors for collecting performance data from the training device and/or the operator of the device, an interface connected to and for receiving the performance data from the one or more sensors and a computer connected to the interface to receive the performance data from the sensors via the interface and for transmitting performance data to the central station. The computer connects to the telecommunications network so that the performance data can be transmitted to the central station. The local stations and the central station have clock means synchronised with a reference time source common to all of them, the performance data transmitted from the local stations to the central stations with associated time data from the clock means enabling users of the system to race against one another in real-time.
Abstract:
Dynamic point selection (DPS) can be implemented using access points having partial or no DPS synchronization. Specifically, a mobile device may broadcast a bounce back message to access points participating in DPS transmissions to signal that a data segment has been successfully received and/or decoded by the mobile device. The bounce back message may cause the access points to drop remaining packets corresponding to the data segment from their buffers without sending those remaining packets over their respective radio interfaces. The bounce back message may be broadcast over any wireless signaling channel, such as via radio link control (RLC) signaling. Moreover, different priorities may be assigned to encoded packets intended for DPS transmission based on whether the encoded packets are communicated over a primary or secondary backhaul path.
Abstract:
Power consumption in a receiving device is avoided by receiving packets from a transmitting device in a first band of frequencies (such as around 60 GHz) and providing acknowledgments in a second band of frequencies that is different than the first band of frequencies (such as around 5 GHz). These out-of-band acknowledgments may allow the receiving device to avoid transmissions in the first band of frequencies and the associated power consumption. Moreover, the transmissions by the transmitting device in the first band of frequencies and the second band of frequencies may be synchronized so that packets are transmitted in the first band of frequencies when transmission in the second band of frequencies is enabled. In these ways, this communication technique may improve the performance of the transmitting device and the receiving device.
Abstract:
Technology for mitigating traffic congestion is disclosed. A master evolved node B (MeNB) can identify service data unit (SDU) packets that are dropped in a retransmission buffer of a packet data convergence protocol (PDCP) layer of the MeNB. The MeNB can create a list of packet data unit (PDU) packets that are dropped at the PDCP layer of the MeNB, wherein the PDU packets that are dropped are associated with the SDU packets. The MeNB can send the list of dropped PDU packets, from the PDCP layer of the MeNB to the PDCP layer of a user equipment (UE), to enable the UE to distinguish between delayed PDU packets and the dropped PDU packets.
Abstract:
A method and apparatus for performing a random access (RA) procedure in a wireless communication system is provided. A user equipment (UE) establishes connection with a first node and a second node, and transmits an RA preamble to the second node. If a number of RA preamble transmissions reaches a maximum number, the UE stops uplink (UL) transmission of all cells in a group to which the second node belongs, and transmits an indication indicating that transmission of the RA preamble has failed to the first node.
