Dynamic clear channel assessment
A first device determines a maximum allowable interference, and transmits a packet including an indicator of the maximum allowable interference. The maximum allowable interference corresponds to an amount of interference that can be present at the first device without preventing proper reception, by the first device, of packets from a second device, or to an amount of interference that can be present at the first device without resulting in a reduction in a Modulation and Coding Scheme of communications between the first and second device. A secondary transmitting device receives an indication of a maximum allowable interference, determines a maximum transmission power according to the maximum allowable interference, and transmits packets during a NAV protection period at a transmission power less than or equal to the maximum transmission power, when the NAV protection period does not reserve the medium the secondary transmitting device.
Uplink transmission parameter selection during random access message transmission and retransmission
Methods, systems, and devices for wireless communication are described for selecting different uplink transmission parameters for transmission or retransmission of a random access message. A user equipment (UE) may transmit or retransmit a random access message such as a layer 2 or layer 3 (L2/L3) message to a base station during a random access procedure. The UE may select a transmission beam, uplink resource or transmission power for the transmission of the L2/L3 message that differ from those used for transmission of a previous random access message. The selection may be based on path loss associated with synchronization signals or previous transmissions. The selection may also be based on a maximum number of retransmissions.
Techniques for uplink transmissions
Various aspects described herein relate to techniques for uplink transmissions in wireless communication systems. In an aspect, a method includes receiving, by a user equipment (UE), hopping information for two consecutive symbols, generating, by the UE, a first symbol of the two consecutive symbols using a format, generating, by the UE, a second symbol of the two consecutive symbols based on the format and the hopping information, and transmitting, by the UE, the two consecutive symbols in an uplink signal.
Establishing additional reverse link carriers in multi-carrier wireless systems
A method and apparatus for reliably and quickly establishing multiple reverse links in multi-carrier wireless networks is provided. Signaling channels are established on an existing forward link in order to transmit reverse link power control bits and the acknowledgment indications.
POWER CONTROL BASED ON SAR AND/OR HARQ
Certain aspects of the present disclosure provide techniques that may be used to manage transmission power at a UE, for example, based on a specific absorption rate (SAR) margin and/or hybrid automatic retransmission request (HARQ) retransmission count.

UE MEASUREMENT REPORTING IN SECONDARY CELL GROUP DORMANCY
A user equipment (UE) may enter a dormant state for a secondary cell group (SCG) of a secondary network (SN) having a primary serving cell (PSCell). The UE may maintain an uplink parameter set for the PSCell while the SCG is dormant for the UE. For example, the UE may receive a parameter change message from either the SN or a master network (MN) and transmit a parameter change acknowledgment to either the SN or the MN. The UE may transmit a periodic measurement report for at least the PSCell to the PSCell of the SN based on the uplink parameter set.
Method and apparatus for uplink repetition on basis of semi-persistent scheduling
A method for a terminal for transmitting a signal in a wireless communication system according to one embodiment of the present invention comprises: receiving repeated transmission related information comprising the count N by which an uplink signal transmission is to be repeated from a base station; determining the transmission power of the uplink signal; and transmitting repeatedly the uplink signal N times by the determined transmission power on the basis of the repeated transmission related information, wherein the terminal can determine the transmission power of the uplink signal on the basis of the count N by which the transmission of the uplink signal is to be repeated. The terminal is capable of communicating with at least one of another terminal, a terminal related to an autonomous driving vehicle, a base station or a network.
5G NEW RADIO WITH SHARING BETWEEN PRIORITY ACCESS LICENSE AND GENERAL AUTHORIZED ACCESS COMMUNICATIONS
A method of wireless communication may include determining a communication operation between a base station and one or more served UEs. The method may further include monitoring for radio frequency (RF) energy on a communication channel at a beginning of a listen before talk (LBT) window of a current frame in a shared spectrum shared between at least one or more opportunistic general authorized users. The method may further include transmitting an LBT trigger signal in response to detection of no RF energy above a minimum energy threshold at the beginning of the LBT window. The method may further include receiving an LBT trigger response signal from the one or more served UEs. The method may also include communicating, by the base station, with the one or more UEs during a channel occupancy time (COT) of the current frame after the LBT window.
