Problems solved by technology

In order to take full advantage of the greater bandwidth available in wireless communication systems, the transmit-receive point TRP may need to provide greater bandwidth and lower latency than existing backhaul and / or fronthaul connections
In addition, the density of TRPs may be much higher than current deployments, and the cost required to lay wired high-capacity backhaul connections across all these TRPs may be prohibitive
Also, in some cases, some TRPs may be temporary or removable and may not support wired connections

Embodiment Construction

[0058] The making and using of the current example embodiments are discussed in detail below. It should be appreciated, however, that the present disclosure provides many applicable inventive concepts that can be implemented in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

[0059] figure 1 An exemplary wireless communication system 100 is shown. The communication system 100 includes an evolved base station (evolved NodeB, eNB) 105 serving multiple user equipment UEs such as UE 110 , UE 112 and UE 114 . In a first mode of operation, transmissions to and from UEs pass through the eNB. The eNB allocates network resources for transmissions to or from UEs. An eNB may also be generally referred to as a base station, NodeB, master base station (master eNodeB, MeNB), secondary base station (secondary eNodeB, SeNB), remote radio head, acces...

Abstract

A method for operating a transmission-reception point (TRP) includes determining a first cycle of backhaul communications modes for the TRP, each backhaul communications mode of the first cycle is associated with a different time period and prompts the TRP to either transmit or receive using a subset of communications beams available to the TRP during an associated time period, wherein the communications beams used by the TRP and neighboring TRPs of the TRP in each associated time period are selected to prevent mutual interference, and wherein at least one backhaul communications mode of the first cycle prompts the TRP to either transmit or receive using all of the communications beams available to the TRP, determining a backhaul frame configuration for the TRP in accordance with the firstcycle, the backhaul frame configuration specifying an arrangement of subframes of a frame used for backhaul communications.
