FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for power supply category and power status reporting in a wireless multi-hop network.

BACKGROUND

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, and/or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, single-carrier frequency-division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

A wireless communication network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A user equipment (UE) may communicate with a base station (BS) via the downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a New Radio (NR) BS, a 5G Node B, and/or the like.

The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a municipal, national, regional, and even global level. New Radio (NR), which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there exists a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies.

SUMMARY

In some aspects, a method of wireless communication, performed by a node in a wireless multi-hop network, may include identifying a power supply category of the node based at least in part on a manner in which the node is supplied with power, wherein the power supply category indicates whether the node is supplied with power from an alternating current power supply or a battery power supply; and transmitting a power status report to another node in the wireless multi-hop network, wherein the power status report indicates the power supply category of the node. In some aspects, the power status report further indicates at least one of: a remaining level of battery power of the node, whether a battery of the node is being charged, a degree to which the battery of the node is being charged, an estimated remaining operating time of the node, or a combination thereof.

In some aspects, a method of wireless communication, performed by a first node in a wireless multi-hop network, may include receiving, from a second node in the wireless multi-hop network, a power status report that indicates a power supply category of the second node, wherein the power supply category indicates whether the second node is supplied with power from an alternating current power supply or a battery power supply; and transmitting an instruction to one or more nodes in the wireless multi-hop network based at least in part on the power status report. In some aspects, the power status report further indicates at least one of: a remaining level of battery power of the node, whether a battery of the node is being charged, a degree to which the battery of the node is being charged, an estimated remaining operating time of the node, or a combination thereof.

In some aspects, a node for wireless communication in a wireless multi-hop network may include memory and one or more processors operatively coupled to the memory. The memory and the one or more processors may be configured to identify a power supply category of the node based at least in part on a manner in which the node is supplied with power, wherein the power supply category indicates whether the node is supplied with power from an alternating current power supply or a battery power supply; and transmit a power status report to another node in the wireless multi-hop network, wherein the power status report indicates the power supply category of the node. In some aspects, the power status report further indicates at least one of: a remaining level of battery power of the node, whether a battery of the node is being charged, a degree to which the battery of the node is being charged, an estimated remaining operating time of the node, or a combination thereof.
