Provided are a method for a first terminal transmitting signals for V2X communication in a wireless communication system and a terminal using the method. The method comprises: mapping V2X data in a first resource area including an N (N is a natural number) number of symbols in a time dimension; and transmitting the V2X data which has been mapped, wherein when an M (M is a natural number smaller than N) number of symbols are included in the time dimension and a second terminal transmits a signal in a frequency division-multiplexed second area to the first resource area, resource elements in the first resource area in an error symbol are excluded from the mapping step, wherein the error symbol is positioned immediately after the M number of symbols in the first resource area.

The present disclosure relates to resource configuration methods and apparatus. In one example method, a first terminal obtains resource indication information, and sends sidelink control information and sidelink data information to a second terminal based on the resource indication information. The resource indication information is used to indicate a symbol or a quantity of symbols occupied by the sidelink control information in one slot or mini-slot.

This document describes systems and techniques directed at concurrent communication in multiple time-division duplex (TDD) bands. As new industry standards (e.g., the Fifth Generation New Radio (5G NR) standard) are being implemented, more TDD bands are becoming available for wireless communications. Generally, manufacturers will add additional antenna systems for each TDD band, but this method may become costly and need extra space, which is already limited, within the user device In various aspects, the concurrent communication system includes a radio frequency (RF) modem module configured to operate on multiple TDD bands, which may include bands that are located near each other on the RF spectrum. The concurrent communication system further includes transceiver circuitry with at least one transmission chain and at least four reception chains. The architecture of this system offers an efficient and inexpensive way to communicate on at least two TDD bands concurrently with reduced hardware cost.

Various communication systems may benefit from an improved signaling protocol. For example, communication systems may benefit from an improved network support for a narrowband internet of things in a hosting long term evolution carrier. A method, in certain embodiments, includes shifting a frequency of a downlink long term evolution channel by a pre-determined amount. The shift causes a duplex distance between the downlink long term evolution channel and an uplink long term evolution channel to change. The method includes blanking at least one overlapping radio resource in at least one of the uplink long term evolution channel or an uplink narrowband internet of things channel. The uplink narrowband internet of things channel and the uplink long term evolution channel at least partially overlap. In addition, the method includes receiving data on the uplink narrowband internet of things channel and an additional uplink narrowband internet of things channel at a network entity from a user equipment.
