Abstract: Embodiments of the present disclosure relate to methods and devices for reference signal allocation. In example embodiments, a method implemented in a network device is provided. According to the method, a plurality of RS configurations are determined based on at least one of the following: different RS ports, or different RS sequences of a same type. At least one first RS configuration from the plurality of RS configurations are allocated for uplink RS transmission by a terminal device served by the network device, and at least one second RS configuration from the plurality of RS configurations are allocated for downlink RS transmission by the network device.

Abstract: The present application discloses an uplink channel transmitting method and a terminal device. The method includes: a terminal device receives uplink grant information transmitted by a network device, where the uplink grant information is used to indicate the terminal device to transmit a first uplink channel and a second uplink channel in a first time unit; and the terminal device transmits, according to priority of uplink channel, at least one of the first uplink channel and the second uplink channel in the first time unit in case that total transmitting power for the terminal device to transmit the first uplink channel and the second uplink channel exceeds maximum transmitting power for the terminal device; where the priority of uplink channel from low to high includes: an uplink channel without HARQ-ACK; and an uplink channel with HARQ-ACK.

Abstract: A method for wireless communications, comprising: signaling, to a user equipment (UE), an indication of one of at least two rules regarding how quasi co-location (QCL) configured for the UE should be applied for one or more DMRS ports; and sending downlink transmission to the UE with the one or more DMRS ports; receiving signaling from a base station and processing signals received on one or more DMRS ports based on the indicated rule. Said method improves communications between access points and stations in a wireless network.

Abstract: Provided herein is a method for performing, by a first apparatus, wireless communication and an apparatus for supporting the same. The method may include the steps of generating a Phase Tracking-Reference Signal (PT-RS), transmitting a Physical Sidelink Control Channel (PSCCH) to a second apparatus, mapping, based on a Cyclic Redundancy Check (CRC) on the PSCCH, the PT-RS to a subcarrier on a Physical Sidelink Shared Channel (PSSCH) resource related to the PSCCH, and transmitting the PT-RS to the second apparatus.

Abstract: The present invention relates to a resource allocation method of a vehicle-to-everything (V2X) transmission terminal in a wireless communication system and an apparatus therefor. More specifically, the method comprises the steps of: transmitting, to a V2X receiving terminal, a first V2X signal for a V2X service; receiving, from the V2X receiving terminal, an acknowledgment/negative-acknowledgment (ACK/NACK) for a V2X signal; and, if the NACK is received from the V2X receiving terminal, allocating, for a second V2X signal, a second time-frequency resource reserved in association with a first time-frequency resource for the first V2X signal.
