摘要： A method of wireless communication of a wireless device in a C-V2X connection may include: determining a first WBEE of a symbol at a first bandwidth, the symbol being associated with no expected C-V2X transmissions, determining a second WBEE of the symbol at a second bandwidth, and identifying an interference based on the first WBEE and the second WBEE. The method may also include notifying an operator of the wireless device about the identified interference.

摘要： Methods, systems, and devices for wireless communications are described. In some examples, a sidelink user equipment (UE) may monitor a set of symbols over a wireless channel. The set of symbols may include at least a first subset of symbols and a second subset of symbols. A quantity of symbols included in the first subset of symbols may be based on a carrier frequency of the wireless channel, a symbol length of the wireless channel, a subcarrier spacing (SCS) of the wireless channel or a capability of the sidelink UE. Further, the sidelink UE may receive a sidelink transmission over the second subset of symbols, where a starting position of the second subset of symbols is defined according to the quantity of symbols included in the first subset of symbols

摘要： Aspects relate to mechanisms for a wireless communication device to select between a cyclic delay diversity mode and an antenna switch diversity mode for transmission of a signal based on at least one parameter associated with communication over a wireless channel. The parameter(s) may include a channel estimation parameter associated with the wireless channel, a communication parameter associated with at least one communication on the wireless channel, or a combination thereof.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to operate in an antenna switch diversity mode to transmit an uplink signal according to an antenna switching pattern, the antenna switching pattern comprising switching between a first transmit chain coupled to a first antenna and a second transmit chain coupled to a second antenna. The UE may transmit at least a first portion of the uplink signal using the first transmit chain coupled to the first antenna, the first transmit chain coupled to the first antenna. The UE may transmit at least a second portion of the uplink signal using the second transmit chain coupled to the second antenna, the second transmit chain coupled to the second antenna.
