Abstract:
Cluster set management may benefit various communication systems. For example, a millimeter wave fifth generation (5G) system may benefit from cluster set management. A method can include receiving accessibility information to one or more access points from a user equipment. The method can also include determining a cluster set for the user equipment based on the received accessibility information. The method can further include communicating an identification of the cluster set to the user equipment.
Abstract:
An example technique may include determining, by a user device, downlink control channel timing information for each of a plurality of access points including for a serving access point that serves the user device and one or more standby access points; sending, by the user device to a cluster set manager via the serving access point, the downlink control channel timing information for each of the plurality of access points; receiving, by the user device from the cluster set manager via the serving access point, downlink control channel allocations including information identifying a downlink control channel allocated to the user device for each of a plurality of the access points; and receiving, by the user device, information from at least one of a plurality of the access points via a downlink control channel allocated to the user device for the at least one of the plurality of access points.
Abstract:
A method and apparatus may determine a plurality of access points. The plurality of access points belong to a cluster set of a user device. The method may also include allocating a plurality of uplink access channels to the plurality of access points. The plurality of uplink access channels may include uplink polling channels. The plurality of uplink access channels are allocated such that the plurality of access channels are staggered in time within a frame structure used by the plurality of access points and the user device.
Abstract:
Various communication systems may benefit from rerouting considerations. For example, fifth generation (5G) systems dealing with radio link failure detection and data rerouting, particularly mmWave 5G systems, may benefit from rapid rerouting methods and systems. A method can include transmitting, from an access point, a downlink control message to a user equipment. The method can also include attempting to detect a Fast-ACK transmission signal from the user equipment in response to the transmitted downlink control message. The method can further include transmitting a rerouting request for the user equipment when the Fast-ACK transmission signal is not detected.
Abstract:
Systems, methods, apparatuses, and computer program products for random access channel (RACH) with a grid of beams for communication systems are provided. One method includes transmitting, by a base station, a beacon signal in one time slot with multiple switched beams, wherein the beams cover an intended coverage area with a grid-of-beams in both horizontal and vertical directions. The method may also comprise switching receiving beams in the grid-of-beams at a network reserved random access channel (RACH) slot by following an identical or directly related beam switching pattern in a downlink (DL) beacon channel. Another method includes detecting, by a user equipment, a beam ID in the downlink beacon channel, selecting the RACH slot using the detected beam ID, and transmitting, by the user equipment, a random access channel (RACH) signature in one or multiple beam blocks within a random access channel (RACH) slot.
Abstract:
An example technique may include measuring a wireless link between a user device and an access point to obtain a first set of measurement values, detecting that the wireless link is temporarily blocked during the measuring, modifying, based on the wireless link being temporarily blocked, the first set of measurement values to obtain a second set of measurement values, and sending, to a network device, a report indicating the second set of measurement values.
Abstract:
A method and apparatus may determine a plurality of access points. The plurality of access points belong to a cluster set of a user device. The method may also include allocating a plurality of random-access-channel slots to the plurality of access points such that the plurality of random-access-channel slots are staggered in time over a random-access-channel period within a frame structure used by the user device.
Abstract:
A method and apparatus can be configured to receive a first scheduling request. The first scheduling request corresponds to a request for a first access point to process data. The method can also include transmitting a second scheduling request. The second scheduling request corresponds to a request to transmit data to a second access point. The transmitting the second scheduling request comprises transmitting the second scheduling request before the data is processed at the first access point.
