Abstract
Provided is a signal forwarding method and related apparatus. In the method, a repeater determines which part of received signals, which are the cellular communication signals, are to be forwarded, according to a control of the network, and then utilizes a gain of the repeater to amplify the determined signals and forwarding the amplified signals. With this method, the effective power spectrum density transmitted by the repeater becomes larger. Multipath or multi-user interference may also be minimized.
Claims16
A signal forwarding method, applied to a first device operating as a repeater, in which the first device is used to amplify cellular communication signals between a second device and a plurality of third devices in a network, the method comprising:
- determining, by the first device, according to a control of the network, which part of received signals are to be forwarded, wherein the received signals are the cellular communication signals;
- and
- utilizing, by the first device, a gain of the first device to amplify the determined signals and forwarding the amplified signals,
- wherein the determining step comprises:
- obtaining required information of repeating signal selectivity transmitted from the network;
- and
- determining which part of the received signals are to be forwarded, based on the obtained required information,
- wherein the obtaining step comprises:
- obtaining a frame number that carries selectivity information and a frame number that will be applied selectivity control,
- wherein the selectivity information comprises symbol duration, symbol number and associated symbol selectivity controls.
A first device, operating as a repeater and used to amplify cellular communication signals between a second device and a plurality of third devices in a network, the first device comprising:
- a Rx circuit;
- a Tx circuit;
- and
- a controller, coupled to the Rx circuit and the Tx circuit, the controller of the first device being configured to:
- determine, according to a control of the network, which part of received signals, are to be forwarded, wherein the received signals are the cellular communication signals;
- and
- utilize a gain of the first device to amplify the determined signals and forwarding the amplified signals,
- wherein the controller is further configured to:
- obtain required information of repeating signal selectivity transmitted from the network;
- and
- determine which part of the received signals are to be forwarded, based on the obtained required information,
- wherein the controller is further configured to:
- obtain a frame number that carries selectivity information and a frame number that will be applied selectivity control,
- wherein the selectivity information comprises symbol duration, symbol number and associated symbol selectivity controls.
