An electronic device comprising circuitry that controls transmitting signals through a first communication link toward a base station or a second communication link toward a mobile station. The second communication link uses an uplink resource of the first communication link. The circuity determines transmission power for the second communication link based on a first parameter and a second parameter. The first parameter indicates a signal level, a power level, or a noise level in the first communication link. The second parameter corresponds to path loss information for the first communication link.

The present disclosure generally relates to the field of resource reservation. More specifically, the present disclosure relates to a technique of reserving communication resources in a wireless communication network. A method embodiment comprises: receiving (S402), by a node of the plurality of nodes, a resource reservation message including first reservation information indicating one or more communication resources for at least one link of the wireless communication network; modifying (S404), by the node, the received resource reservation message by including second reservation information indicating one or more communication resources for a link of the node in the received resource reservation message; and transmitting (S406), by the node, the modified resource reservation message to one or more neighbor nodes of the node.

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).

Techniques are described for wireless communication. A first method includes receiving a transmission including a paging group indicator and an indication of a time window. The transmission may be received at a user equipment (UE) over an unlicensed radio frequency spectrum band. The first method may also include monitoring, based on the paging group indicator, the unlicensed radio frequency spectrum band during the time window to receive an asynchronous paging message from a base station. A second method includes transmitting the transmission over the unlicensed radio frequency spectrum band; performing a number of clear channel assessments (CCAs) on the unlicensed radio frequency spectrum band during the time window; and transmitting the paging message over the unlicensed radio frequency spectrum band at a transmission time during the time window. The transmission time may be based on a result of at least one of the CCAs.

An Unlicensed Band (Uband) reference signal sending method, receiving method and devices are provided, a Uband channel includes multiple predetermined candidate transmission positions for transmitting a reference signal, and each candidate transmission position is a transmission occasion for the reference signal. The sending method includes that: an Evolved Node B (eNB) senses whether the Uband channel is idle or not at all or part of the candidate transmission positions, and determines idle candidate transmission positions; and the eNB selects to send the reference signal to User Equipment (UE) at all or part of the idle candidate transmission positions according to historical Uband channel contention state information.

The disclosure relates to a method for mitigating interference of a first radio signal received by a first transceiver of a first radio access technology (RAT) due to transmission of a second radio signal by a second transceiver of a second RAT, wherein the first transceiver and the second transceiver are physically collocated on a same device. The method includes: pre-setting a power of the second radio signal based on a throughput performance requirement for the first radio signal before transmission of the second radio signal, and tuning the power of the second radio signal during transmission of the second radio signal based on estimating the interference of the first radio signal.
