There are provided a light source device, which is more compact and inexpensive than a known light source device, and an endoscope system having a compact and inexpensive light source device. In a light source device, a light source unit includes a first light source that emits blue light, a second light source that emits broadband green light including not only a green component but also a red component, and an optical filter that adjusts the amount of broadband green light for each wavelength. The optical filter has a characteristic in which the reflectance of the green component is smaller than the reflectance of the red component in the case of reflecting the broadband green light or a characteristic in which the transmittance of the green component is smaller than the transmittance of the red component in the case of transmitting the broadband green light.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling identifying a configuration for a reference signal comprising a single carrier waveform and associated with single carrier signals for a plurality of symbol periods, the configuration indicating a plurality of channels associated with the reference signal and a set of functions associated with the reference signal. The UE may receive, according to the configuration, the reference signal in a first one or more symbol periods of the plurality of symbol periods and the single carrier signals on the plurality of channels in a second one or more symbol periods of the plurality of symbol periods. The UE may perform the set of functions on the received single carrier signals based at least in part on the received reference signal.

A base station transmits, to a wireless device, configuration parameters of a control resource set in a bandwidth part (BWP), and the control resource set includes resource block (RB) sets of the BWP. The base station transmits a control information via one or more control channel elements (CCEs) of first CCEs within a first RB set of the RB sets. The base station receives, from the wireless device, a signal via an uplink resource based on an index of a CCE of the one or more CCEs of the first CCEs. The index is determined based on first index values, of the first CCEs within the first RB set, starting from a same initial value as that of index values of CCEs within each respective RB set of the RB sets.

A method and system for transmitting data is provided. The method includes receiving by a first interface device, data. The data is divided into a plurality of data packets and stored within an internal buffer. A first group of data packets are transmitted to a network node communicatively coupled to the first interface device. The first group of data packets are transmitted from the first communication device to a second interface device via a first communication network. A second group of data packets are transmitted to a first communication device communicatively coupled to the first interface device. The second group of data packets are transmitted from the first communication device to the second interface device via a second communication network associated with the first communication device.

The present disclosure provides a method in a network device. The method includes: obtaining a node configuration associated with a set of Transmitting/Receiving Points, TRPs; selecting, from the set of TRPs, one or more IAB TRPs associated with a terminal device based on the node configuration and similarity metrics between an initial position estimate and historical positioning results for the terminal device; and transmitting a measurement request to a serving TRP associated with the terminal device and each of the one or more IAB TRPs; receiving, from each of the serving TRP and at least one of the one or more IAB TRPs, a measurement report indicating a Timing Advance, TA, associated with that TRP and the terminal device.

A method for performing transmission or reception by a first communication node (511) in at least one of: a first set of time-frequency resources (1201) and a second set of time-frequency resources (1202) in a frame (1200). The first and the second set of time-frequency resources (1201, 1202) are reserved for communication of reference signal and/or control information in a pre-arranged direction of: transmission and reception to or from one or more second communication nodes (512). The first communication node determines (1301) that the direction of communication of at least one of the first and second set is to be switched for at least one frame (1200). The first communication node also performs (1306) transmission or reception of control information in at least one of the first and second set of time-frequency resources (1202) according to the determined switched direction to or from, one or more third communication nodes (513).

This application provides a data transmission method. The method may include: determining that a position of a start bit of a first bit sequence and a position of an end bit of a second bit sequence are contiguous in a coded bit sequence, where the first bit sequence is a bit sequence in first transmission, the second bit sequence is a bit sequence in second transmission, the first transmission and the second transmission carry a same transport block, and the second transmission is previous transmission of the first transmission; and receiving and/or sending the first bit sequence.

Disclosed are a method and system for assigning a C-RNTI (Cell Radio Network Temporary Identity), aiming to assign the C-RNTI to UE in an aggregation scene of different eNBs by UE. The method comprises the following steps: in the scene that the User Equipment (UE) aggregating the resource of multi-eNBs, the initial access eNB and the target eNB UE aggregated respectively determine the C-RNTI which should be assigned, and then assign the determined C-RNTI respectively to the UE; or, the initial access eNB assigns the specific C-RNTI for bearer separation to UE, wherein the C-RNTI is on a presetting range of the bearer separation specific Radio Network Temporary Identity (RNTI) which is maintained by the eNB UE aggregated.

The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method and an apparatus for handling physical uplink control channel (PUCCH) resource for enhanced beam failure recovery (BFR) in wireless communication system are provided.

Opportunistic networking systems can utilize one or multiple bands/channels that are shared with other radio access technologies (RATs) (such as wireless local area networks (WLAN, such as Wi-Fi) and mmWave). An unconventional carrier type (UCT) can be defined to support opportunistic networking in licensed and/or unlicensed spectrum. For example, a primary base station can determine a secondary base station activated for use with user equipment (UE). The primary base station can schedule data to be sent to the UE via the secondary base station. The secondary base station can provide discovery information, reserve a wireless channel, transmit the data and/or release the channel (implicitly, explicitly, or by reservation).
