Methods and apparatus for partial interference reduction within wireless networks
摘要
說明書
In one exemplary embodiment, the BS “community” (i.e., two or more designated BS that cooperate) can directly communicate among one another to transmit future schedules. Such communications can occur over literally any type of communications or network interface, whether wireline or wireless, and ideally is supported via extant communication channels between the base stations that support operation of the cellular network. For deterministic non-data signals of high repetition, this communication is implemented according to a protocol, such as one comprising messaging that minimally includes a request and response, or alternatively a periodic broadcast (multi-cast). For non-deterministic non-data signals, messaging may comprise a notification and an acknowledgment. For example, in one exemplary implementation, the BS 202 communicates their scheduling information within a 3GPP LTE system via the X2 interface 208 and associated protocol of the type previously referenced herein.
As an alternative to direct scheduling, the BS may also indirectly determine the schedule of neighboring BS. Enabled BS deployments with legacy devices may require the BS to determine the neighboring BS non-data transmissions in the same method that a UE typically would (e.g. reception and evaluation of a neighboring BS radio broadcast).
