Abstract: Methods, systems, and devices for wireless communications are described for prioritization of sidelink communications of a user equipment (UE) with one or more access link communications. A prioritization scheme may provide inter-UE and intra-UE prioritization that may be used to prioritize sidelink communications and one or more access link communications. Inter-UE prioritization may be used at the UE to determine whether to cancel all or a portion of a sidelink communication that uses resources indicated in a cancellation indication from a base station, or to transmit the sidelink communication irrespective of the cancellation indication. Intra-UE prioritization may be used at the UE to determine which of one or more access link communications or a sidelink communication is to be maintained or canceled in the event of overlapping resources between the access link and sidelink communications.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may allocate a set of information bits into multiple subsets of bits corresponding to channel instances of a channel. The transmitting device may encode a first subset of bits according to a first channel coding scheme for a first channel instance and a second subset of bits according to a second channel coding scheme for a second channel instance. The transmitting device may input encoded subsets of bits to a polarizing transform, which may output a set of encoded polarized bits that are transmitted to a receiving device. Upon reception of the encoded polarized bits, the receiving device may apply a depolarizing transform to obtain multiple subsets of bits corresponding to channel instances of the channel, and may decode each subset of bits according to a respective channel coding scheme.

Abstract: A receiving device identifies a collision between first resources reserved by a first transmitting device and second resources reserved by a second transmitting device and transmits a collision indication to the first transmitting device or the second transmitting device based on the identified collision. A transmitting device that receives a collision indication from the receiving device backs off from transmitting during the resources received by the resource reservation in response to receiving the collision indication from the receiving device.

Abstract: Aspects relate to a demodulation reference signal (DMRS) in a sidelink wireless communication network. In some examples, a sidelink device generates a DMRS based on first and second identifiers of the sidelink device. In some examples, a sidelink device generates a DMRS based on an initialization parameter and/or at least one scaling parameter. In some examples, the initialization parameter may be based on a first identifier of a sidelink device. In some examples, the at least one scaling parameter may be based on a second identifier of a sidelink device. In some examples, a first sidelink device synchronizes with a second sidelink device based on broadcast channel information that is obtained by using DMRS information to decode a received broadcast signal. In some examples, the DMRS information may be based on first and second identifiers of the first sidelink device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from one or more additional UEs, one or more indicators corresponding to one or more resource reservations. Accordingly, the UE may transmit data, to a second UE, on a sidelink channel, with at least one resource reservation, of the one or more resource reservations, indicated within a control element transmitted with the data. For example, the control element may include a list or a bitmap indicating the at least one resource reservation. Numerous other aspects are described.

Abstract: Aspects presented herein may enable a transmitting device to encode and transmit coordination information and data in separate transport blocks, such that the transmitting device may update the coordination information without altering the transport block carrying the data. In one aspect, an apparatus encodes coordination information for sidelink resources in a first transport block. The apparatus encodes data in a second transport block. The apparatus transmits a first transmission on a PSSCH, the first transmission including the first transport block comprising coordination information and the second transport block.

Abstract: A first UE may determine that a BPL with a second UE has degraded below a threshold and generate, based on the determination, a beam training frame for an on-demand beam training procedure. The beam training frame may include a first AGC symbol, SCI indicating that the beam training frame is for beam training, and one or more sets of an AGC symbol and beam sweeping reference signals. The first UE may transmit the beam training frame multiplexed with one or more data frames to the second UE. The second UE may receive the beam training frame for the on-demand beam training procedure based on a determination that the BPL with the first UE has degraded below the threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A network node may store, in a first buffer, a first set of transport blocks (TBs) received at the network node over a wireless channel during a first time window. The network node may store, in a second buffer, a second set of TBs received at the network node over the wireless channel during a second time window and according to at least one monitoring criterion. The network node may receive a first set of one or more network coding messages over the wireless channel. The network node may decode the first set of one or more network coding messages based on the first set of TBs in the first buffer. The network node may transmit a second set of one or more network coding messages corresponding to a portion of the second set of TBs in the second buffer.

Abstract: Aspects of the disclosure relate to wireless communications including sidelink communications between wireless devices. Adaptation of a resource exclusion reference signal receive power (RSRP) threshold for scheduling resources for a device using such sidelink communications includes utilization of first and second time/frequency windows of available resources to determine the number of free resources in each window. If the free resources in either window are less than a predetermined free resource threshold, the resource exclusion RSRP threshold is increased to gain further potential time/frequency resources that may be scheduled by the device.
