Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a power headroom (PHR) value for a component carrier (CC) based at least in part on a physical uplink shared channel (PUSCH) transmission in the CC, wherein the PUSCH transmission includes a first repetition associated with a first set of power control parameters and a second repetition associated with a second set of power control parameters, and wherein the PHR value is determined based at least in part on one or more of the first repetition or the second repetition. The UE may transmit information identifying the PHR value for the CC. Numerous other aspects are provided.

A communication system is disclosed in which a home base station operates a home cell and a macro base station operates a macro cell. The home base operates a cell located at least partially within the macro cell. The home base station can obtain information identifying a quantity of home base stations that each operate at least one respective cell that is located at least partially within the macro cell and from this information, and further information identifying resource usage via said home base station, can set a target power for said home base station.

A message relay arrangement is described. A first terminal sends a first message to a second terminal, where the first message that instructs the second terminal to determine a type of the second terminal based on the first message. Based on the terminal type, the second terminal operating as the first-type terminal sends first measurement information; or operating as the second-type terminal receives first measurement information sent by a first-type terminal, determines quality of a first link between the first-type terminal and the second-type terminal, and sends the quality of the first link to the first terminal. The first terminal receives the quality of the first link sent by the second-type terminal. The first terminal determines a mapping relationship between the first-type terminal and the second-type terminal based on the quality of the first link. The first terminal sends the mapping relationship to terminals corresponding to the mapping relationship.

The present technology relates to a wireless communication apparatus and method, and a program which enable communication to be performed more efficiently. The wireless communication apparatus includes a preamble generating unit configured to generate a preamble signal including header information, an inter-training generating unit configured to generate an inter-training signal including at least part of information of the header information, and a wireless transmission processing unit configured to transmit transmission data after transmitting the preamble signal in at least one or more frequency channels among a plurality of the frequency channels and transmit a plurality of the inter-training signals by utilizing one or a plurality of the frequency channels among the plurality of the frequency channels during a transmission period of the transmission data. The present technology can be applied to a wireless communication apparatus.

Aspects of the present disclosure provide techniques for addressing scenarios where the minimum transmit power supported by a wireless node (e.g., an Integrated Access and Backhaul (IAB) node) is above a minimum value specified by a standard. In some cases, the node may signal information regarding its power configuration so a network entity of the may take it into account (e.g., when allocating or scheduling resources). The power configuration may include an indication of the minimum transmit power supported by the node and/or an indication of a guard band that may help the IAB control adjacent channel leakage.

An infrastructure equipment as part of a mobile communications network receives an indication that data is to be transmitted to one of communications devices. In response the infrastructure equipment transmits a first paging message to the communications device to indicate the communications device is to receive the data via a wireless access interface. If a response to the transmitted first paging message is not received within a predetermined time, then if the infrastructure equipment can use a power boosting mode, to transmit the first paging message with a boosted power, or if the infrastructure equipment cannot use a power boosted mode for transmitting, to transmit a second paging message to one or more communications apparatus which can operate as a relay node for the communications device. The second paging message identifies the relay node and the communications device for which the infrastructure equipment is to transmit the data.

The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

Wireless networks share UE location information in order to identify possible inter-network aggressors. If a first network determines, based on the location data it receives from a second network, that one of the first network's UEs may cause excessive interference to one or more of the second network's UEs, the first network grants A-MPR to its UE (e.g., by signaling the UE). The first network's UE can then lower its transmit power in order avoid interfering with the second network's UE.

Aspects of the disclosure relate to techniques for peak-to-average power ratio (PAPR) reduction based on a tone reservation (TR) algorithm. For a TR algorithm, a suitable subset of tones from among a full set of tones in a given resource allocation are reserved for use as peak reduction tones (PRT). An apparatus such as a transmission/reception point receives a set of one or more PRT sequences and stores them in memory. The transmission/reception point then determines a set of PRTs based on one or more later-received PRT sequence selection parameters. Other aspects, embodiments, and features are also claimed and described.

Techniques for determining beam-sweeping patterns for synchronization signals transmitted in a region by several access nodes in a network, where each access node is connected to a corresponding array of antenna elements. An example method includes modeling a total power function for the power transmitted in the synchronization signals, as a factor graph having a plurality of check nodes and variable nodes, each check node corresponding to a virtual wireless device in the region and each variable node corresponding to an available beam for an access node. The virtual wireless devices are emulated so as to implement quality-of-service constraints on synchronization signals received by the virtual wireless devices. An iterative message-passing algorithm, such as a min-sum algorithm, is applied to the modeled total power function, to determine a sequence of power levels, for each access node, for sweeping synchronization signal beams, so as to minimize the total power function.
