Abstract:
Various communication systems benefit from suitable allocation. For example, system for vehicle to X communication may benefit from semi-persistent resource allocation mechanisms, for example, for uplink semi-persistent scheduling. A method can include configuring at least one main semi-persistent scheduling occasion to a user equipment. The method can also include configuring at least one subsequent semi-persistent scheduling occasion to the user equipment. The at least one subsequent semi-persistent scheduling occasion can depend on usage of the at least one main semi-persistent scheduling occasion.

According to an aspect, a method comprises: determining, autonomously by a terminal device of a wireless communication system, to request for establishment of parallel connections with multiple access nodes; transmitting, by the terminal device, at least one access request to a plurality of access nodes; and receiving, by the terminal device at least one response to the at least one access request from at least one radio access node, wherein the response contains information related to establishment of the parallel connections.
Abstract:
A method is provided including configuring, by a network node, a set of resources to be used by at least one user equipment for transmitting a first type of uplink data; receiving from the at least one user equipment information that indicates that at least one resource in the set of resources comprises a second type of uplink data different than the first type of uplink data; and decoding data received on the at least one resource based on the information.
Abstract:
Systems, methods, apparatuses, and computer program products for controlling vehicle-to-vehicle (V2V) interference are provided. One method may include receiving, by a base station, timing information from a user equipment, and determining a timing difference between network timing at the base station and at least one of global navigation satellite system (GNSS) timing at the base station or the received timing information. The received timing information comprises at least one of a global navigation satellite system (GNSS) timing at the user equipment or a timing difference calculated based on a network timing at the user equipment and the global navigation satellite system (GNSS) timing at the user equipment.
Abstract:
First and second level discovery messages for device-to-device discovery are determined to be going to be transmitted, resource(s) are requested for transmission of at least the second level discovery message, and allocated resource(s) of a second type are received. The first level discovery message is transmitted on either a selected resource of the first type or a selected one of the allocated resource(s). The second level discovery message is transmitted on a selected one of the more allocated resource(s) of the second type, A first level discovery message is received on a resource of either a first type or a second type. It is determined whether the received message is of interest or not and if the message is of interest, then it is determined whether a second level discovery message is available and if so, the second level discovery message is received on a resource of the second type.
Abstract:
A method and related user equipment for radio resource control connection recovery are disclosed. In an exemplary embodiment, the method comprises: detecting a RLF of a radio link between a first user equipment and a radio access node; informing a second user equipment which communicates with the radio access node via the first user equipment to suspend a radio resource control connection state; executing a radio resource control connection reestablishment procedure with the radio access node; and informing the second user equipment to resume the radio resource control connection state if the radio resource control connection reestablishment is successful. In addition, a method and related user equipment used with radio resource control connection recovery are disclosed.
Abstract:
Systems, methods, apparatuses, and computer program products for configuring a dual-mode SL LCH with simultaneous mode 1 and mode 2 transmission are provided. One method may include configuring one or more dual-mode sidelink (SL) logical channels (LCHs) to at least one user equipment to enable simultaneous sidelink mode 1 and sidelink mode 2 transmission. The method may also include receiving, from the at least one user equipment, at least one sidelink (SL) buffer status report (BSR) that may optionally comprise buffer status for one or more of the configured dual-mode logical channels (LCHs) according to a network configuration, and transmitting, to the at least one user equipment, a resource allocation that can be applied for the dual-mode logical channels (LCHs) according to the network configuration.

Abstract:
Embodiments relate to an apparatus comprising means for predicting, for a first node at a first location, at least one second location(s) of said first node. The first node may be configured to transfer data to a second node via a first sidelink; for example, the first and second nodes may be part of a mobile communications network. The apparatus may further comprise a means for estimating a first radio parameter of the first sidelink at said second location(s). The apparatus may further comprise a means for determining, based on said estimated first radio parameter, if said first sidelink at said second location(s) meets at least one selection criterion.
