Abstract: Radio resource is allocated to a subscriber module in a fixed wireless access cellular wireless system comprising an access point and a plurality of subscriber modules at static locations, each subscriber module having a directional antenna aligned with the access point, and the area of coverage of the access point having a plurality of sectors, each sector being served by a respective radio transceiver of the access point. The same frequency allocation is allocated to each sector, the radio resource for each sector being allocated as a plurality of time slots each having the same frequency allocation. A suitability of the subscriber module for time slot re-use is determined based on a first criterion. If is suitable for time slot re-use based on the first criterion, time slots are allocated for communication to the subscriber module that are also allocated to an adjacent sector.

Abstract: This disclosure details a base station and client devices using dynamic spectrum access for communication within a frequency spectrum by selecting channels dynamically for efficient communication. This includes identifying active uplink and downlink channels from an available list and allocating them to multiple client devices based on their locations, with some devices sharing common active channels. A downlink channel is designated as a beaconing channel, used for beaconing with embedded information, including the coordinates of a region among a plurality of regions, available channels for the region, and a buffer slot in the channels, during a beaconing period occurring outside regular transmission times. Acknowledgments with medium access control (MAC) commands for an identified subset of client devices sharing an active channel are grouped and transmitted, with each message in the plurality of messages on the uplink channels followed by a downlink acknowledgment.

Abstract: In a wireless communication system, dynamic changes of a code block (CB) to resource element (RE) mapping type may improve decoding performance in some scenarios. A user equipment may provide an indication of a preferred CB mapping type. A base station may transmit a physical downlink shared channel (PDSCH) based on a first dynamic CB mapping type in one or more slots. A UE may receive the PDSCH and determine a second CB mapping type that is preferred by the UE based on a metric. The UE may transmit an indicator of the second CB mapping type, for example, as a one-bit or two-bit indicator, which may be coupled with a channel state information (CSI) report or signaled in uplink control information (UCI) independently from a CSI report. The base station may consider the indicator when selecting a new dynamic CB mapping type for the UE.

Abstract: Embodiments may relate to group addressed frame delivery over multi-link systems. Systems and methods are configured for identifying, by an access point (AP) multilink device (MLD) in a wireless network, a first sequence number space (SNS) that is to be used by the AP MLD to transmit data to a non-AP MLD over a first communications link and a second communications link, wherein frames with identical data that are transmitted over the first and second communications links will have an identical first SN based on the first SNS; identifying, by the MLD in the wireless network, the first SN based on the first SNS; and transmitting, by the AP MLD in the wireless network, a frame that includes the data to the non-AP MLD based on the first SN.

Abstract: Methods and apparatuses for multi-slot scheduling on unlicensed spectrum are disclosed. A method comprises: receiving a downlink control information (DCI) for scheduling time-contiguous data transmission in multiple slots, wherein the DCI includes an indicator indicating the time domain resource allocation in the multiple slots; determining, based on the indicator, a starting position and an ending position of the scheduled time-contiguous data transmission; and transmitting, in response to a successful listen-before-talk (LBT), data from the determined starting position to the determined ending position.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may start a timer or counter in connection with failing to transmit a feedback message at a time for which the feedback message is scheduled for transmission. The UE may defer transmission of the feedback message for one or more attempts at transmitting the feedback message. The UE may perform one of: transmitting the feedback message before expiration of the timer or before the counter satisfying a count threshold, or discarding the feedback message after expiration of the timer or in connection with the counter satisfying the count threshold. Numerous other aspects are provided.

Abstract: A communications method and apparatus are provided. A network device determines whether a first capability of a terminal device is less than or equal to a second capability of the terminal device. The first capability is a capability of the terminal device of working at a first frequency when the terminal device supports only a first radio access technology, and the second capability is a capability of the terminal device corresponding to the first frequency in a first frequency combination. When the first capability is less than or equal to the second capability, the network device sends a first message to the terminal device. The first message is used to indicate the terminal device to measure a second frequency, the first message does not include a configuration of a first measurement gap, and the first measurement gap is used to measure the second frequency.

Abstract: Systems and methods of communication synchronization are described herein. An exemplary system includes two or more radios and a cloud controller. The two or more radios are collocated with one another and they communicate with two far radios over a pair of long range wireless links. The two or more radios are configured to transmit and receive in synchronization with one another on a same channel. An off-axis response for each of the two or more radios is reduced compared to their on-axis response for improved signal to noise ratio. The on-axis response of the two or more radios being substantially equal to one another.
