Aspects relate to mechanisms for a wireless communication device to configure and indicate sidelink control information (SCI) for sidelink communication within a slot over a sidelink channel. The SCI can include first stage SCI (SCI-1), second stage SCI (SCI-2), and third stage SCI (SCI-3). The SCI-1 may be transmitted within a control region of the slot, whereas the SCI-2 and the SCI-3 may be transmitted within a data region of the slot. The SCI-2 may include information for decoding SCI-3, including, for example, a resource size, modulation order, and rate-matching behavior of the SCI-3. The sidelink communication can further include sidelink data traffic that may be communicated in the data region of the slot.

Third stage sidelink control information design

The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may transmit a list of a plurality of CCs for a transmission of at least one PDCP PDU, the plurality of CCs corresponding to a plurality of indicated CCs. The apparatus may also transmit the at least one PDCP PDU on one or more CCs of the plurality of CCs. Additionally, the apparatus may determine whether to retransmit the at least one PDCP PDU, a retransmission of the at least one PDCP PDU being associated with a PDCP duplication procedure. The apparatus may also select one or more CCs of the plurality of CCs for the retransmission of the at least one PDCP PDU.

Enhancement of PDCP duplication

Embodiments of the present disclosure provide a method performed by a communication device. The method includes obtaining, in frequency domain, channel estimation for a transmission unit for a channel between the communication device and another communication device, and calculating correlation coefficients for the transmission unit based on the channel estimation. The method also includes obtaining a delay spread for the channel from the calculated correlation coefficients.
