摘要： A base station that monitors one or more channel conditions of an unlicensed carrier to detect whether there is an interfering signal in the unlicensed carrier. The base station may detect an interfering signal that, for instance, is hidden from and difficult to detect by a WCD that has UL data to send. If the base station detects an interfering signal on the unlicensed carrier, it proceeds with transmitting a UL grant message to the WCD, however, the base station may configure the transmission of the UL grant message to the WCD based on the interfering signal. For instance, the base station may determine, based on the interfering signal, when to transmit the UL grant message, or may determine, based on the interfering signal, UL transmission parameter values to include in the UL grant message, or any combination thereof.

摘要： A wireless device receives configuration parameters comprising: first parameters of logical channel(s) indicating that each logical channel of the logical channel(s) is mapped to corresponding first transmission duration(s); and a second parameter indicating a first value for a buffer status report timer. The buffer status report timer is started with the first value in response to: receiving at least one uplink grant associated with a second transmission duration; and at least one logical channel, with data, of the logical channel(s) mapped to the second transmission duration. A buffer status report is transmitted in response to the buffer status report timer expiring.

摘要： Provided are a method for transmitting a buffer status report (BSR), and a device thereof, and to: a method by which a first terminal transmits and receives a BSR required for performing device-to-device communication with a second terminal in order to efficiently allocate a wireless resource to be used for the device-to-device communication; and a device therefor. Specifically, provided are a method and a device by which the first terminal performs device-to-device communication with the second terminal. Such a method includes triggering a BSR for the device-to-device communication with the second terminal, transmitting the BSR to a base station or a wireless resource allocation entity, and receiving wireless resource allocation information for the device-to-device communication with the second terminal from the base station or the wireless resource allocation entity.

摘要： This disclosure provides a Scheduling Request transmission method (10) for decoupled downlink-uplink in heterogeneous network, where the heterogeneous network comprises at least two cells in charge of downlink and uplink transmission separately and connected with any backhaul, the method comprising: determining (11) a positive Data Scheduling Request, D-SR, is to be transmitted in a current D-SR's subframe together with HARQ-ACK/NACK on PUCCH using PUCCH format 1a/1b/3; transmitting (12) a HARQ-ACK/NACK in the current D-SR's subframe on PUCCH together with a negative D-SR using PUCCH format 1/1a/1b or format 3 while transmitting a Scheduling Request, SR, in a next SR's subframe subsequent to the current D-SR's subframe. In this method, the Scheduling Request (SR) of the UEs can be correctly detected in the Pico base station to trigger UL transmission in decoupled UL/DL scenario in various case and any kinds of backhaul can be supported.

摘要： Uplink data is transmitted efficiently. A terminal device includes: a reception unit configured to receive a parameter included in an RRC message and receive downlink control information, by using a physical downlink control channel; and a higher layer processing unit configured to store an uplink grant as a configured uplink grant. The configured uplink grant is delivered to a HARQ entity in a case that the parameter is configured and a Semi-Persistent Scheduling release is indicated by using the downlink control information, and the configured uplink grant is cleared in a case that the parameter is not configured and the Semi-Persistent Scheduling release is indicated by using the downlink control information.

摘要： Network nodes and methods therein are provided for cooperation between different wireless communications networks, such as between a 3GPP network and a WLAN. Information related to a buffer status of at least one wireless device is provided by a first network node operating in a first wireless communication network, to a second network node operating in a second wireless communication network. The information may be an indication of a buffer status of a UE which the first network node considers steering to the second wireless network. The second network node may reply with an estimate of a possible throughput for the UE, where the estimate is based on the information related to a buffer status.

摘要： Depending on data (110) available in an uplink data buffer (400) of a communication device (10) for uplink transmission and further depending on uplink radio resources previously allocated to the communication device (10) for the uplink transmission in reoccurring time intervals, a fraction (111-1) of the data (110) available in the uplink data buffer (400) is determined. A buffer status report is sent to the cellular network. The buffer status report indicates the determined fraction (111-1) of the data (110).

摘要： A first apparatus may send, to a base station in a first carrier frequency, a request associated with determination of a first beam used for communication between the base station and the UE. The first apparatus may communicate with the base station in a second carrier frequency based on the request associated with the determination of the first beam, the first carrier frequency being different from the second carrier frequency. A second apparatus may receive, from a base station in a first carrier frequency, a message associated with determination of a first beam used for communication between the base station and the UE. The second apparatus may communicate with the base station in a second carrier frequency based on the message associated with the determination of the first beam, the first carrier frequency being different from the second carrier frequency.
