Abstract:
A method for communication includes accessing all sub-channels in a communication frame, generating a counter that counts down beginning with a received first listen before talk (LBT) communication symbol, determining whether the counter reaches zero before receiving a second LBT communication symbol, determining whether a desired number N of contiguous sub-channels are available, and if the desired number N of contiguous sub-channels are available, transmitting an LBT symbol.
Abstract:
Various aspects of the present disclosure relate to vehicle-to-vehicle (V2V) data sharing. The sensor data collected from each vehicle may be divided into common information and detailed information. The common information is broadcasted to every other nearby vehicle. Based on the received common information other vehicles may express interest in some particular detailed information. Unicast and/or multicast sessions may be set up to share the detailed information with the interested vehicles.
Abstract:
Techniques are described for wireless communication at a wireless device. One method includes transmitting, during a TTI, a first message using a first MCS; and transmitting, during the TTI, a second message using a second MCS. The first message includes indications of a location, a heading, and a speed of the wireless device, and the second MCS is higher than the first MCS. Another method includes decoding a first message received during a TTI; performing a Doppler effect compensation for a second message based at least in part on the first message; and decoding the second message based at least in part on the Doppler effect compensation. The second message is also received during the TTI. The first message is decoded in accordance with a first MCS, and the second message is decoded in accordance with a second MCS, with the second MCS being higher than the first MCS.
Abstract:
Techniques are described for wireless communication. A method for wireless communication at a first base station (e.g., corresponding to, associated with, or included in a first cell) includes receiving location information from a vehicle; identifying, based at least in part on the location information, a plurality of cells from which to broadcast a location message associated with the vehicle, where the plurality of cells include at least a cell of a second base station; and communicating with at least the second base station regarding a broadcast of the location message. A method for wireless communication at a vehicle include transmitting location information from the vehicle to a base station on an access stratum (AS) layer, and transmitting location message information to the base station. Numerous other aspects are provided.
Abstract:
The disclosure generally relates to avoiding physical cell identifier (PCI) collision and confusion using LTE-Direct expressions. In particular, a small cell may discover LTE-Direct expressions that include PCIs associated with neighbor small cells and select (or reselect) a local PCI to ensure that the local PCI differs from the PCIs associated with each neighbor small cell. Furthermore, the small cell may detect PCI confusion where multiple neighbors broadcast LTE-Direct expressions with the same PCI and different E-UTRAN Cell Global Identifiers (eCGIs) and/or detect PCI confusion in neighbor small cells where the local PCI matches the PCI used in a neighbor's neighbor and the local eCGI used in the small differs from that used in the neighbor's neighbor. The small cell may additionally broadcast LTE-Direct expressions that include at least the local PCI and eCGI to enable neighbors to avoid PCI collision and confusion in the same manner.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a priority for performing a wide area network (WAN) operation or a device-to-device (D2D) operation using a downlink receive chain, and performs the WAN operation or the D2D operation using the downlink receive chain according to the priority. In another aspect, the apparatus determines downlink resources on which a WAN operation is performed, refrains from scheduling the WAN operation on the downlink resources when the WAN operation is not scheduled or expected to be scheduled on the downlink resources, and sends to a device priority information indicating a priority for the device to perform the WAN operation or the D2D operation using a downlink receive chain when the WAN operation is scheduled or expected to be scheduled on the downlink resources.
Abstract:
A method of operating a wireless device includes displaying an advertisement on the wireless device. In addition, the method includes differentiating the display of the advertisement based on at least one criterion in order to indicate to a user of the wireless device a satisfaction of the at least one criterion. A method of operating a server includes receiving at least one criterion. In addition, the method includes differentiating a display of an advertisement based on the at least one criterion in order to indicate to a user of a wireless device a satisfaction of the at least one criterion. Furthermore, the method includes sending the differentiated advertisement for display on the wireless device.
Abstract:
An apparatus, a method, and a computer program product of a wireless device are provided in which a first device identifier of a wireless device is provided. An allocation record is received that includes an expression used for discovery, a second device identifier, and at least one of a digital signature of a first server that delegates the expression or a digital signature of a second server that manages the expression. The allocation record is verified. An apparatus, a method, and a computer program product of a first server are provided in which a device identifier is received from a wireless device. An allocation record is generated that includes an expression used for discovery, the device identifier, and at least one of a digital signature of the first server or a digital signature of a second server that manages the expression. The allocation record is sent.
Abstract:
Methods and apparatus for generating, communicating, and/or using sets of addresses corresponding to a communications device are described. A first communications device generates, from a public key and a random number, both a first address and a second address. The generated address pair is communicated to a second communications device along with proof of ownership information regarding the address pair via an address signaling message such as a binding update message. The second communications device processes the received address signaling message and determines address pair validity and/or address pair ownership information. The first address may be associated with a first network, e.g. , an unsecure WAN network, while the second address may be associated with a second network, e.g. , a secure peer to peer network. Decisions on switching between using the first address to using the second address may be based on address validity and/or address ownership determinations.
Abstract:
An apparatus and method for providing gateway relocation to an external network wherein a user equipment (UE) includes an initial external network connection via a source core node, e.g., a PDNGW, comprises initializing a mobility event, reallocating the initial external network connection from via the source core node to via a target core node to create a new external network connection, allocating the new IP address to the UE for the new external network connection, and using the new IP address. The UE may have several bearers established, including local breakout bearers.
