Problems solved by technology

However, these two standard schemes have different potential problems: firstly, the physical uplink control channel (PUCCH) mechanism requires the availability of uplink beam pairs, which is not always satisfied because in many cases the downlink and Uplink beams may be the same
So in many cases when the downlink beam fails, the uplink beam also fails
Second, non-contention-free Random Access Channel (RACH) mechanism is very expensive in terms of resources, since non-contention (reserve space) needs to be maintained for each scheduled UE in the uplink resource, which is only available when the beam fails will be used
So this is not resource efficient

Abstract

The present invention relates to a first communication device for communicating with a second communication device and a third communication device using beamforming in a wireless communication network, wherein the first communication device is adapted to communicate with the second communication device in response to In the event of beam failure, a new beam is determined from a plurality of available beams of the second communication device, and a beam failure recovery request (BFRQ) message is sent to the third communication device, wherein the BFRQ message includes the first The communication device determines information about the new beam and receives a BFRQ response message from the second communication device.

Description

technical field [0001] Generally, the present invention relates to communication networks. More particularly, the present invention relates to a communication device for communicating using beamforming in a wireless communication network. Background technique [0002] Beamforming is widely used in the 5G New Radio (5G NR) standard. Beam failures in 5G NR usually occur in all serving beams (an allocated set of beams, which can be accessed by the receiving device (such as UE) from the serving gNB or Transmit and Receive Point (TRP) to the corresponding User Equipment (UE). ) selection and use. Not all of them are used at the same time) occurs when all of them fail, eg, the Packet Error Rate (PER) of all these allocated serving beams is too high for a certain period of time. This beam failure may occur because the UE transmits movement, or there is an object blocking the current beamforming link between the TRP and the UE, causing the beam direction of these serving beams to ...
