Provided are a channel or signal sending method and apparatus, and a storage medium. The method includes: if a transmission direction configuration of the first carrier or the first carrier group indicates that an uplink transmission is sent within the transmission time of the first transmission, sending, by a terminal, the first transmission, and canceling the sending of the second transmission or sending the second transmission with reduced power; otherwise, performing, by a terminal, at least one of the following modes: sending the first transmission, and canceling the sending of the second transmission or sending the second transmission with reduced power; sending the second transmission, and canceling the sending of the first transmission or sending the first transmission with reduced power; determining whether to send the first transmission or the second transmission by the terminal itself.

The present application is related to a method performed by a user equipment (UE). The method includes: obtaining a power based at least in part on path-loss of a link between the UE and a base unit; obtaining another power based at least in part on path-loss of a sidelink between the UE and another UE; selecting one of the power and the abovementioned another power as transmission power; and transmitting data on the sidelink using the transmission power.

According to an aspect, there is provided an apparatus for performing the following. The apparatus is configured to, first, allocate one or more of a plurality of available physical resource blocks to a plurality of terminal devices, wherein the allocating is performed so that a power spectral density for the plurality of terminal devices matches or exceeds a pre-defined limit or a plurality of respective pre-defined limits for power spectral density. In response to one or more physical resource blocks being still available following said allocating, the apparatus is configured to further allocate at least one of the one or more physical resource blocks still available to at least one of the plurality of terminal devices, wherein the further allocating is performed so that at least a pre-defined value for a modulation and coding scheme index is sustainable for said at least one of the plurality of terminal devices.

For scheduling transmissions of data channels, control channels, or random access channels using downlink control information (DCI) formats, a DCI format can configure a transmission of one or multiple data channels over respective one or multiple transmission time intervals. A first DCI format can configure the parameters for a channel transmission and a second DCI format can trigger the channel transmission and indicate respective one or more transmission time intervals.

Techniques for optimizing antenna parameters of a radio configured to transmit on spectrum shared by incumbent user(s) are disclosed. The incumbent user has priority to use the shared spectrum over the radio. The antenna parameters are optimized to reduce interference to incumbent user(s) and/or other radios utilizing the shared spectrum whilst maintaining satisfactory coverage area.

This disclosure pertains to a method for operating a user equipment (10) in a radio access network, the method comprising transmitting signaling based on an emission control parameter, the emission control parameter being based on a TTI configuration and/or structure. There are also disclosed related devices and methods.

Certain aspects of the present disclosure provide techniques for enhancing sidelink resource utilization for a user equipment (UE) that supports full duplex (FD) communications. For example, an FD UE may receive incoming sidelink communication over a first set of resources and, in FD mode, simultaneously transmit another sidelink communication over the same first set of resources. According to aspects of the present disclosure, the potential interference between the two sidelink communications will be mitigated or reduced, such as by having the FD UE negotiate with other sidelink UEs over transmission power levels and related aspects, such as beam coordination and/or resource subset designation, or the like.

Methods, systems, and devices for wireless communication are described. In some wireless systems, a base station may configure a user equipment (UE) for random access (RACH) message transmission in dedicated RACH resources during, for example, a handover process. The contention-free random access (CFRA) resources may allow the UE to transmit RACH messages at a higher transmission power than contention-based random access (CBRA) resources. The base station may indicate, to the UE, RACH transmission parameters for CFRA that are different than parameters for CBRA. These parameters may include configuration information, frequency division multiplexing information, RACH retransmission parameters, target received power, response window length, etc. The UE may use the indicated RACH transmission parameters to transmit a RACH message to the base station. The base station may respond with a RACH response message, and the base station and UE may synchronize upon completion of the RACH procedure.

A wireless system is shared amongst a hierarchal tier of entities. A communication management resource receives notification that a second-tier priority entity has been allocated use of a second wireless spectrum as a replacement to first wireless spectrum. In one embodiment, the first wireless spectrum is revoked from the second-tier priority entity based on use of the first wireless spectrum by a first-tier priority entity (such as incumbent entity). The communication management resource controls a wireless transmit power level of a third-tier priority entity in the hierarchy to provide protected use of the second wireless spectrum by the second-tier priority entity. According to one configuration, the communication management resource controls a power level of wireless communications transmitted by a wireless base station operated by the third-tier priority entity.

The disclosure provides a method and a device in a node for wireless communication. A first node receives a first signal and a second signal, and the first node transmits a first information block and a second information block in a first time window. The first information block and the second information block are used for determining whether the first signal and the second signal are correctly received respectively; transmit power values of physical layer channels carrying the first information block and the second information block are both a first power value. Through the design in the disclosure, a transmit power of a feedback channel on a sidelink is associated with a priority; and when multiple feedback channels are transmitted in one same time window, a proper transmit power can be determined to optimize performances of the feedback channels on the sidelink.
