A communication method and apparatus are provided, which relate to the field of communication technologies, to improve communication performance of a terminal device and improve resource utilization of a communication system. The method includes: a terminal device receives measurement information from a network device, where the measurement information indicates one or more measurement objects, and the measurement information includes one or more of the following: information about a measurement object of a serving cell, information about intra-frequency measurement of a neighboring cell, and information about inter-frequency measurement of a neighboring cell; and the terminal device performs, based on a reference signal associated with one or more measurement objects corresponding to a first bandwidth part (BWP), one or more of the following measurements: radio resource management (RRM) measurement, radio link monitoring (RLM) measurement, and beam failure recovery (BFR) measurement.

Various aspects of the disclosure relate to reporting power headroom of an apparatus such as a user equipment (UE). For an apparatus that uses beamforming, the power headroom associated with the beam the apparatus is using for wireless communication (e.g., with a base station) may be lower than the power headroom associated with another beam that the apparatus could use for the wireless communication. The disclosure relates in some aspects to using one beam for wireless communication and using the power headroom for another beam for a power headroom report. In this way, the apparatus may always report its full transmit power capability.

Maps of high wireless device movement and high wireless device traffic are created. These maps are correlated over selected periods of time to determine when, and where, large numbers of wireless devices are both moving and creating problematic traffic. Stationary wireless devices using an access node in the problem area are identified before the selected time period (e.g., 30 minutes before commuting time). These stationary wireless devices are handed over to a reserved frequency band. During the selected time period, wireless devices requesting access in the problem area are denied access using the reserved frequency band and are instead forced to use another frequency band.

Systems, methods, and computer-readable media herein dynamically assign user devices to communicate to cell sites and antenna arrays using either a first wireless communication protocol or a second wireless communication protocol. The sector power ratio (SPR) for a wireless communication protocol is monitored to determine if a key performance indicator (KPI) should be monitored. Once the SPR exceeds a pre-determined threshold, the KPI is monitored to determine to what degree, if any, the KPI has exceeded a threshold value. An upper limit to the number of user devices allowed to communicate to the cell cite using the first wireless communication protocol is then modified at least in part based on the SPR and the KPI values. User devices are then re-assigned from the first to the second wireless communication protocol based on the modified upper limit of user devices allowed to use the first wireless communication protocol.

A wireless device receives radio resource control message(s) from a base station indicating random access resources of an uplink bandwidth part of a cell, that comprises two-step random access resources. The wireless device may determine, while the two-step random access type and a four-step random access type are available for transmitting a preamble, that the two-step random access resources comprise contention-free two-step random access resources. The wireless device may also select from among the two-step random access type and the four-step random access type, the two-step random access type. The wireless device may then transmit a preamble to the base station using the two-step random access resources, based on the two-step random access type.

The present invention belongs to the field of communications, and discloses a cell handover method and a device. The method includes: determining, by a first base station to which a primary carrier cell belongs and according to a measurement report sent by user equipment UE, whether soft handover needs to be performed for the UE; if soft handover needs to be performed for the UE, transferring, by the first base station, a radio bearer RB between the first base station and the UE to a second base station to which a secondary carrier cell belongs; and selecting, by the first base station, a target cell according to the measurement report, and handing over the UE to a target base station to which the target cell belongs. The present invention can avoid service interruption caused when cell handover is performed for UE.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, in a first time slot, a set of resources to use for transmission to another UE; evaluate, in a second time slot, whether one or more resources of the set of resources is available; and transmit, based on the one or more resources of the set of resources being available, information to the other UE in a third time slot and using the set of resources, or reselect, based on the one or more resources of the set of resources being unavailable, another resource for transmission of the information to the other UE. Numerous other aspects are provided.
