Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently selecting resources for sidelink communications in a shared spectrum while allowing other user equipment (UEs) a chance to gain access to the shared spectrum. In one aspect, a UE may transmit sidelink data to another UE in accordance with a frequency hopping pattern to randomize interference and improve throughput. According to some aspects, the first UE may transmit the sidelink data on a first set of interleaved frequency resources in a first time interval and a second, different set of interleaved frequency resources in a second time interval. In another aspect, a UE may rely on feedback from other UEs to determine when reserved resources are released, and the UE may use the released resources for sidelink communications.

Wireless communication transmission and reception techniques are described. At transmitter, source data bits are modulated into a number Nd of constellation symbols. An invertible transform is applied to the constellation symbols, thereby resulting in mapping the transformed symbols into Nd elements in the time-frequency grid.

Some implementations more specifically relate to LTF designs that support distributed transmissions. In some aspects, a transmitting device may obtain a sequence of values representing an LTF of a PPDU and may map the sequence of values to a number (N) of noncontiguous subcarrier indices of a plurality of subcarrier indices spanning a wireless channel according to a distributed tone plan. In some implementations, the transmitting device may modulate the sequence of values on N tones, representing a logical RU, and map the N tones to the N noncontiguous subcarrier indices, respectively. In some other implementations, the sequence of values may be obtained based on relative locations of the N noncontiguous subcarrier indices in the wireless channel.

A communication device 1 determines, between a first physical channel and a second physical channel of the communication device 1, an accommodation state of a session in a wireless resource of the first physical channel. The communication device 1 issues an instruction of changing a part of the wireless resource of the first physical channel to a wireless resource of the second physical channel, based on the above-mentioned accommodation state.
