Aspects presented herein may improve the efficiency of power boosting of PDCCH by a base station and the blind PDCCH detection/decoding performed by a UE. In one aspect, the UE receives, from a base station, a power boost indication for a PDCCH. The UE determines at least one search space based on the power boost indication from the base station. The UE monitors for the PDCCH with the indicated power boost from the base station in the at least one search space. In another aspect, a base station transmits, to a UE, a power boost indication for a PDCCH. The base station applies a power boost to the PDCCH. The base station transmits the PDCCH with the power boost to the UE.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may determine, based at least in part on a first model, an estimated position of the first wireless communication device. The first wireless communication device may determine, based at least in part on a second model, an estimated direction for transmission of a packet to a second wireless communication device. The first wireless communication device may determine, based at least in part on a third model, an estimated transmit power for transmission of the packet. The first wireless communication device may determine, using a neural network, a narrow beam based at least in part on the estimated position, the estimated direction, and the estimated transmit power. The first wireless communication device may transmit the packet on the narrow beam to the second wireless communication device. Numerous other aspects are provided.

A method of demodulating a channel by a user equipment in a wireless communication system, include the steps of receiving information including a total power value of reference signals (RSs), a power difference value between power of a first RS for control information and a power of a second RS for data among the RSs, a port number of an additional RS, a cyclic shift (CS) value of the additional RS, and a power value of the additional RS and a power difference value between second RSs for the control information, performing channel estimation on a first channel on which the additional RS is received and a second channel received from a port identical to the port number of the additional RS and the second channel on which the first RS to which a CS value different from the CS value of the additional RS is applied is received, obtaining a power difference value between the power of the additional RS and the power of the first RS based on the channel estimation of the first and the second channels, and determining a number of rank of the second RS based on the total power value of the RSs, the power value of the additional RS, a power difference value between the power of the first RS and the power of the second RS, the obtained power difference value between the power of the additional RS and the power of the first RS, and the power difference value between the power of the second RSs.

There is provided a method, performed by a receiving node, for generating composite acknowledgement information for a Hybrid Automatic Repeat Request, HARQ, process. The composite acknowledgement information is generated in response to transport blocks received from a transmitting node. The method comprises the step (301) of providing, for each transport block, a positive acknowledgement/negative acknowledgement, ACK/NAK, indication for each of a plurality of transmissions of the transport block to define a respective set of ACK/NAK indications. The method also comprises the step (302) of generating the composite acknowledgement information based on the respective sets of ACK/NAK indications for the transport blocks over the plurality of transmissions. In this way, by considering respective sets of ACK/NACK indications over a plurality of transmissions, it is possible to generate an appropriate composite acknowledgment. A direct consequence of the proposed technology is that the composite acknowledgement information is generated as a positive acknowledgment, ACK, if two transport blocks have been successfully received even though the two transport blocks do not belong to the same transmission.

A vehicle-to-vehicle (V2V) communication transponder for use in V2V communication, safety, optimization and anti-collision systems wherein the transponder records and shares observed traffic signal timing and phasing, and uses this information to make recommendations or perform automatic operation to optimize parameters such as safety, gas mileage, travel time, and overall traffic flow. Methods for sharing and making recommendations are described. Embodiments include considerations of traffic and road history in recommendations. No central authority, road-side equipment, (RSU), or pre-determined lane maps are required. Embodiments include a hybrid protocol using both TDMA and CSMA. Some embodiments are free of MAC and IP addresses. Embodiments include equipped vehicles and V2V system using the transponder.

The present invention concerns a method (PR) for detecting an identifier (Id) for starting a motor vehicle (V), said motor vehicle comprising a first antenna (A1) and said identifier (Id) comprising a second antenna (A2).

Methods, systems, and devices for wireless communication are described. A wireless device may receive a configuration message that includes overlapping basic service set (OBSS) coordination parameters. The OBSS coordination parameters may be used to select an OBSS preamble detection (PD) threshold or a transmission (TX) power, or both. For example, an OBSS coordination parameter may include an indication of an OBSS PD threshold or the TX power or a range of OBSS PD thresholds or TX powers. In some cases, the coordination parameter may include selection criteria that may be used to select the indicated OBSS PD threshold or TX power. Additionally or alternatively, a range of selection criteria may be used to select from a range of OBSS PD thresholds and TX powers. The wireless device may use the selected OBSS PD threshold or TX power to communicate with an AP or other devices.
