Abstract: A first number of wireless devices in communication with an access node over a first frequency band is determined. A total bandwidth and a spectral efficiency of the first frequency band are determined, and a throughput provided to each of the first number of wireless devices in the communication between the access node and the first number of wireless devices is calculated. Based on the total bandwidth of the first frequency band, the spectral efficiency of the first frequency band, and the throughput provided to each of the first number of wireless devices, a second number of wireless devices permitted to communicate with the access node over the first frequency band is determined. To determine a third number of wireless devices permitted to communicate with the access node over the first frequency band, the throughput provided to each of the first number of wireless devices is adjusted.

Abstract: Devices, systems, and methods to reduce interference in heterogeneous networks having a plurality of access nodes, such as combinations of macro cells, micro cells, pico cells, femto cells, etc. are disclosed. Interference caused in sectors of two or more access nodes that face each other is minimized by dividing a total number of resource blocks into resource block sets that are uniquely numbered and allocated across each sector of each access node. The allocation is rotated based on a different time stamp or a different starting number, or may be a random sequence of sets per access node. These independent allocations for each access node generally distribute the interference across the system, and provide better interference reduction, resulting in an increase in system capacity per sector of each cell.

Abstract: Scheduling full-duplex transmissions includes configuring adjacent time slots of an air interface resource with different ratios of uplink portions, downlink portions, and flexible portions, scheduling transmissions in each adjacent time slot based on whether or not the transmissions are latency-sensitive or delay-sensitive or control transmissions. The uplink portions, downlink portions, and flexible portions comprise symbols within time slots of a subframe, and can vary based on a numerology. The flexible portions are symbols configured to simultaneously transmit uplink data and downlink data.

Abstract: A method of operating a communication system includes communicating a traffic channel information stream with a wireless device using a first air-interface scheme while communicating control channel information with the wireless device using the first air-interface scheme. The control channel information is communicated with the wireless device using the first air-interface scheme is used to handover the wireless device from the first air-interface scheme to a second air-interface scheme. After the handover of the wireless device from the first air-interface scheme to the second air-interface scheme, the traffic channel information stream is communicated with the wireless device using the second air-interface scheme while still communicating control channel information with the wireless device using the first air-interface scheme.

Abstract: A wireless device is determined to be in communication with a first access node is at a location in a coverage area of a first communication network, and it is determined whether the wireless device is in communication with the first access node using a first radio access technology or a second radio access technology. The availability of the first r and the second radio access technologies from the first communication network are determined, and the wireless device is permitted to register with the PTT communication system when the wireless device is in communication with the access node using the first radio access technology. Further, the wireless device is prevented from registering with the PTT communication system when the wireless device is in communication with the access node using the second radio access technology and the first radio access technology is available for the wireless device.

Abstract: Reference signals (a.k.a., pilot signals) are broadcast to aid in at least channel estimation, cell selection, and handover. When a multi-antenna mode (i.e., MIMO) is used data signals on one antenna should not interfere with reference signals on another antenna. Reference signal resource elements (a.k.a., slots) being broadcast from one antenna are multiplied by a first Walsh code and the data (or reference) signal resource elements being broadcast from another antenna are multiplied by second Walsh code in the same family. Multiplication by Walsh codes reduces or eliminates the correlation between the data resource elements on a first antenna and the reference signal resource elements simultaneously broadcast on a second antenna.

Abstract: Push-to-talk messages are sent via a wireless multicast channel to multiple push-to-talk groups of devices regardless of group membership. Thus, all of the devices using the multicast channel receive all of the push-to-talk messages. To separate messages bound for one push-to-talk group from those bound for another, a push-to-talk group specific orthogonal code is applied to each message. The devices in a specific group use the group specific orthogonal code to decode the received multicast messages. If a device decodes the multicast message with the correct group specific orthogonal code, then the message is decoded and the device can play the message. If a device decodes the multicast message with a different group specific code (i.e., because it is not a member of the group the message was intended for), the message is will not be properly decoded and thus will be unplayable or scrambled.

Abstract translation: 一键通消息通过无线组播信道发送到多个即按即说的设备组，而不管组成员身份。 因此，使用多播信道的所有设备都接收所有即按即说消息。 为了将绑定到一个即按即说组的消息与绑定另一个一键通组的消息分开，对每个消息应用即按即说组特定的正交码。 特定组中的设备使用组特定正交码来解码所接收的多播消息。 如果设备使用正确的组特定正交码解码多播消息，则消息被解码，并且设备可以播放消息。 如果设备使用不同的组特定码来解码多播消息（即，因为它不是该消息所针对的组的成员），则该消息将不被正确解码，因此将不可播放或加扰。

Abstract: A wireless communication system serves a first wireless device with a first access node using a frequency band and serves a second wireless device in an adjacent cell with a second access node that uses the same frequency band. The communication of a first resource block is scheduled between the first wireless device and the first access node. The communication of a second resource block between the second wireless device and the second access node is also scheduled. The scheduling of the first resource block and the second resource block correspond in time and frequency. The first resource block is encoded with a first orthogonal code from a family of orthogonal codes. The second resource block is encoded with a second orthogonal code from the family of orthogonal codes. After encoding, the first resource block and the second resource blocks are transmitted using the frequency band.

Abstract: A first cell is selected as a center cell for testing. Downlink transmissions from a one or more surrounding cells are loaded with test load levels. The downlink transmissions, when loaded with test load levels, include a selected amount(s) of the data portions of their transmission frames carrying orthogonal channel noise (OCN). A performance indicator of the center cell is measured/determined while the surrounding cell(s) are transmitting test load levels and while the center cell is communicating user traffic between the center cell and a first plurality of wireless devices. The test load levels of the surrounding cells may also include user traffic in addition to the OCN.
