A resource scheduling method and a related device configure a scheduled resource for a terminal device based on a dynamic analog beam determined by a network device, thereby increasing a throughput of the terminal device. The network device determines, based on information about an SRS of each first terminal device, a set of second terminal devices from a set of first terminal devices and static analog beam information of each second terminal device in the set of second terminal devices. Then, the network device determines beam domain channel information based on the static analog beam information. As such, the network device determines dynamic analog beam information of each second terminal device based on the static analog beam information and the beam domain channel information.

Resource scheduling method and related device

The present disclosure discloses example broadcast beam processing methods and apparatuses. One example method includes sending a first broadcast beam. A first measurement report is received from a first terminal after the first broadcast beam is sent, and a weak coverage area of the first broadcast beam is determined based on the first measurement report. A second broadcast beam is then sent, where the second broadcast beam is used to cover the weak coverage area of the first broadcast beam.

Broadcast beam processing method and communications apparatus

This application provides a method for adjusting a half-power angle of an antenna, to adjust a maximum half-power angle or a maximum beam gain of an individual transceiver channel. The method includes: first determining that M antenna elements in N antenna elements connected to a first transceiver channel of an access network device need to be turned on or off, where N>M≥1, and both N and M are integers, that is, a quantity of antenna elements driven by the first transceiver channel needs to be adjusted; and then sending first indication information to the access network device, where the first indication information is used to indicate to turn on or off the M antenna elements.

A method for adjusting a half-power angle of an antenna, to adjust a maximum half-power angle or a maximum beam gain of an individual transceiver channel, includes: first determining that M antenna elements in N antenna elements connected to a first transceiver channel of an access network device need to be turned on or off, where N&#x3e;M&#x2265;1, and both N and M are integers, that is, a quantity of antenna elements driven by the first transceiver channel needs to be adjusted; and then sending first indication information to the access network device, where the first indication information is used to indicate to turn on or off the M antenna elements.

A measurement method, a terminal device, and a network device are described. The measurement operation includes sending a channel state information-reference signal CSI-RS measurement beam to a terminal device. The CSI-RS measurement beam is obtained by the network device by weighting a CSI-RS by using a beamforming weight, and the beamforming weight is used to perform beamforming on the CSI-RS. The measurement operation further includes receiving a rank indicator and a channel quality indicator that are determined based on the CSI-RS measurement beam. The measurement operation further includes weighting and transmitting a downlink channel based on the rank indicator and the channel quality indicator. The CSI-RS is weighted and transmitted by using the beamforming weight, to help improve accuracy of rank measurement, thereby improving a user throughput.

Embodiments of the present invention relate to a method for improving handover performance in a cellular wireless communication system, said cellular wireless communication system employing a handover procedure in which a handover preparation for a mobile station is initiated if a channel quality value between a source cell for said mobile station and said mobile station is less than a channel quality threshold value; said method comprising: tuning said channel quality threshold value based on one or more handover performance criteria used in said cellular wireless communication system. Furthermore, the invention also relates to a device for improving handover performance, a computer program, and a computer program product thereof.

Method for improving handover performance in a cellular wireless communication system

An apparatus configured to operate in a telecommunications network comprising a first base station configured to serve at least a first cell and a second base station configured to serve at least a second cell, wherein said apparatus comprises a controller configured to receive measurements related to a successful handover of a user equipment from a first cell to a second cell, wherein said measurements relate to measurements being taken before and/or during said handover.

An automatic technique for a timely diagnostic uses a cloud service and includes (1) after a memory dump file is generated, uploading the dump file and system configurations to an analysis server, (2) extracting key call stacks from the dump file in the server, (3) searching a cloud-based knowledge base for entries corresponding to contents of the call stack and the system configurations (like model, SW version, etc.), these entries representing known issues having similar call stack contents and/or system configurations. If relevant knowledge base entries are found, then they are used to identify a root cause and suggest solutions. If no relevant knowledge base entries are found, this result is reported along with any other potentially useful data from the dump file analysis, such as an identification of a product area for a program identified by the dump file name.

Memory dump file collection and analysis using analysis server and cloud knowledge base

Described are methods, systems, and apparatus for reducing storage system polling when collecting and providing storage system state data. A plurality of poll requests for storage system state data is received. For each poll request of the plurality of poll requests, a poll request arrival time associated with the poll request is stored. A first poll is initiated to collect first storage system state data for a first poll request of the plurality of poll requests. A first poll start time associated with the first poll is stored. The first poll is completed, forming the first storage system state data. For each poll request of the plurality of poll requests, the first storage system state data is provided for the poll request provided that the poll request arrival time is before the first poll start time.
