Abstract:
During device-to-device communication between two devices, a communication transmitted from a first UE to a second UE may not be reliably received by the second UE if the first UE is traveling at high speed. Therefore, a travel speed of a transmitting UE may be considered in determining a transmission configuration. According to an aspect, the UE may determine a travel speed of the UE. The UE may determine, based on the travel speed of the UE, a transmission configuration of the UE for device-to-device communication. The UE may transmit the device-to-device communication based on the transmission configuration.
Abstract:
A procedure to select a UE as a relay between a machine-type communication (MTC) device and a base station is desired to improve communication between the MTC device and the base station. The apparatus may be a machine-type communication user equipment (M-UE). The apparatus transmits, to one or more user equipments (UEs), an access request to request access to a base station through one or more of the one or more UEs as a relay. The apparatus receives an access request response from the base station, the access request response including selection information about selection of at least one of the one or more UEs as a relay between the M-UE and the base station.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The apparatus may transmit a message in a first subset of a set of resources. The message may include a position of the apparatus and a resource ID indicating at least one symbol in a second subset of the set of resources for transmitting a sequence. The apparatus may transmit the sequence in the at least one symbol in the second subset of the set of resources identified by the resource ID, receive at least one other sequence, adjust a transmission timing based on the received at least one other sequence, and transmit, based on the adjusted transmission timing, the sequence in one or more symbols in a third subset of the set of resources.
Abstract:
When a UE in a first cell operating at a first frequency attempts to discover another UE in a second cell operating at a second frequency, the UE in the first cell may need to constantly monitor communication on the second frequency to discover the UE in the second cell, which may not be desirable. According to an aspect of the disclosure, the apparatus receives, on a first frequency of a first channel from a first base station serving a first cell, discovery information associated with a second frequency of a second channel corresponding to a second cell, wherein the first frequency is a downlink (DL) frequency and the second frequency is an uplink (UL) frequency. The apparatus discovers, based on the received discovery information, one or more UEs on the second frequency of the second channel.
Abstract:
A user equipment (UE) may be outside of the coverage area of a base station or other access point, which may impede access by the UE of a core network, server, or the like. Therefore, a UE may establish a relay connection to access resources when the UE is outside of a coverage area provided by a base station or access point. In aspects, an apparatus may be configured to transmit, to a set of relay UEs, a first message associated with establishment of a relay connection. The apparatus may be further configured to receive a set of messages from the set of relay UEs. The apparatus may be further configured to establish the relay connection with a first relay UE of the set of relay UEs based on a message of the set of messages from the first relay UE.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives information from a serving base station and at least one neighboring base station. The information indicates a time allocation of discovery resources allocated by each of the serving base station and the at least one neighboring base station for performing direct discovery. The apparatus further determines a subframe timing of the serving base station and the at least one neighboring base station, and performs direct discovery using the time allocation of the discovery resources allocated by each of the serving base station and the at least one neighboring base station based on a determined subframe timing of the serving base station or a neighboring base station corresponding to the discovery resources.
Abstract:
An improved manner of transmitting and receiving messages in V2X/V2V/D2D is presented in which a transmitting device determines a geographic location of the mobile transmitting device and generates a message for a service group having a group ID associated with the service group, the message comprising a first indication of a geographic area associated with the message, the geographic area based at least in part on the geographic location of the transmitting device. Then, the apparatus transmits the message to the service group, e.g., via V2X/V2V/D2D communication. A receiving device then determines its geographic location and determines whether to send a feedback for the message based on the first indication of the geographic area associated with the message and the geographic location of the receiving device.
Abstract:
Some aspects described herein relate configuring resources in one or more slots for communicating a sidelink synchronization signal (SLSS) while maintaining a logical numbering of multiple consecutive slots including the one or more slots. Based on configuring the at least one slot a SLSS can be received from a node or transmitted to one or more nodes during at least one slot of the one or more slots.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive navigation information associated with a user equipment (UE). The network node may transmit, based at least in part on the navigation information and a handover boundary, an indication for the UE to perform a handover between a terrestrial network (TN) and a non-terrestrial network (NTN). Numerous other aspects are described.
