    摘要： Systems, methods, devices, and computer program products are provided. Operations thereof include sending, by a first system and to a user equipment, an activation notification that activates a dangerous area and causes the user equipment to increase a reporting granularity corresponding to a location of the user equipment. The dangerous area corresponds to an area that includes a vehicle operating therein. The reporting granularity is increased relative to a first reporting granularity. Operations include receiving, from the user equipment, location reporting data that is provided at the increased granularity and sending, to a second system, a first notification that corresponds to determining that the VRU will be in the dangerous area.

    摘要： The disclosure relates to signalling of transmissions with shortened TTI. The disclosure further relates to an RBS and a method performed at the RBS of scheduling resources for a wireless communication device. The disclosure still further relates to a wireless communication device and a method performed at the wireless communication device of being granted data transmission or data reception. In a first aspect of the disclosure, a method performed at an RBS is provided for scheduling resources for a wireless communication device including indicating a grant of a resource for the wireless communication device to transmit or receive data based on DCI and a position of the DCI within a data frame of a downlink control channel.

    摘要： Systems and methods are described herein for scheduling multiple short Transmission Time Internal (sTTI) transmissions. In some embodiments, a method of operation of a network node of a wireless communication network for scheduling multiple sTTI transmissions comprises transmitting a control information message to a wireless device for two or more sTTI transmissions, wherein the control information message comprises scheduling information indicating two or more scheduled sTTIs for the two or more sTTI transmissions, respectively, and/or an indication of a timing for the two or more scheduled sTTIs for the two or more sTTI transmissions and/or an indication of a Demodulation Reference Signal (DMRS) configuration for the two or more scheduled sTTIs for the two or more sTTI transmissions. By using multi-sTTI scheduling, control signaling overhead is reduced.

    摘要： A method and device for two-step random accessing. The method includes transmitting a random access preamble and a data block on a time-frequency resource to a network device; and receiving a response message for the random accessing from the network device. The data block is encoded with an orthogonal cover code and/or a cyclic shift, and the data block comprises data information and a reference signal associated with the data information. Therefore, resource efficiency is improved significantly for an associated data message following a random access preamble with endurable minor performance degradation.
