Various communication systems may benefit from improved wireless communications. For example, communication systems may benefit from a wireless broadband network that monitors and detects link latency. A method includes detecting latency information of data being transmitted on at least one link between a first base station and at least one second base station. In addition, the method includes forming at least one array comprising the latency information of the data. Further, the method includes modifying a system behavior relating to at least the first base station or the at least one second base station based on the at least one array.

Link latency and system behavior

There is provided a method comprising determining a first subset of cells served by a first base station to be suitable for handover to a user equipment associated with a second base station, the subset comprising at least one but not all of the cells served by the first base station and providing information to the second base station from the first base station, said information comprising an indication of the determined first subset of cells.

Serving cell management

Various communication systems may benefit from improved signaling. For example, certain communication systems may benefit from improved signaling before network access is revoked through a citizens broadband radio service. A method may include receiving at a network entity from a citizens broadband radio service device a warning message. The warning message may include a drop time after which communication between a network and a user equipment using the citizens broadband radio service will terminate. The method may also include triggering the performing of an action based on the warning message by the network before the drop time.

Warning of spectrum access revocation

In accordance with an example embodiment of the present invention, methods, apparatae and software products are presented for enabling transmission by devices requiring a priori and periodic authorization from a spectrum access server for transmission.

Method and apparatus for controlling high power transmission

Various communication systems may benefit from improved radio frequency transmissions. For example, communication systems may benefit from the selection of a frequency band based on measurements of a spectrum surrounding the user equipment. A method, in certain embodiments, may include taking measurements by a base station of a spectrum of an environment surrounding a user equipment. The method may also include determining based on the measurements and radio frequency capabilities of the base station at least one desired frequency for transmission by the user equipment. In addition, the method may include sending a request from the base station to a network entity requesting a grant of the at least one desired frequency for transmission by the user equipment.

Frequency selection for broadband transmissions among a shared spectrum

A method, a system and a computer device for initiating bi-directional compression of a video stream in a packet switched network, based on delay tolerance of a service or application. A video frame recompression (VFR) utility determines an end-to-end (E2E) delay tolerance retrieved from a Real-time Transport Control Protocol (RTCP) report. The VFR utility then determines the actual expected delay based on a deep inspection of packet headers. The VFR utility utilizes a processing opportunity delay (which determines whether the E2E delay tolerance is greater than the actual expected delay) to reprocess video content comprising Intra-coded (I) pictures/frames and Predicted (P) frames to improve compression efficiency. The VFR utility may also utilize a complexity ratio which is a ratio of the I-Frame rate and the P-Frame rate to select frames for compression. The VFR utility recompresses video content by replacing P-Frames with B-Frames.
