摘要： Wireless communications systems and methods related to reclaiming of resources in a shared frequency spectrum shared by multiple operators are provided. A first wireless communication device associated with a first operator of a plurality of operators identifies a transmission opportunity in a shared frequency spectrum shared by the plurality of operators, wherein the first operator has priority among the plurality of operators for accessing the shared frequency spectrum in the transmission opportunity. The first wireless communication device communicates with a second wireless communication device associated with the first operator, in the transmission opportunity without a prior reservation of the transmission opportunity.

摘要： Multiple base stations, which may be controlled by different network operators, share a transmission medium to serve multiple user equipment (UE). A first base station determines that the shared communication medium is free. The first base station transmits, during a first medium access slot on the shared communication medium, a pre-grant for a first UE associated with the first base station. The first UE transmits a response message during the first medium access slot. Optionally, a second base station may join the transmission by transmitting a pre-grant to a second UE during a subsequent medium access slot.

摘要： Wireless communications systems and methods related to sharing a frequency-division duplexing (FDD) spectrum among multiple network operating entities. In one embodiment, a first wireless communication device communicates, with a second wireless communication device in a downlink (DL) frequency band, a reservation signal in a first channel sensing time slot of a frame to reserve a transmission time slot in the frame. The first wireless communication device communicates, in an uplink (UL) frequency band, an UL control signal in the first channel sensing time slot. The UL frequency band and the DL frequency band are shared by a plurality of network operating entities for frequency-division duplexing (FDD) communications. In another embodiment, a first wireless communication device communicates, in a first frequency band of a FDD network shared by a plurality of network operating entities, a reservation signal to reserve the first frequency band for time-division duplexing (TDD) communications.

摘要： Aspects of the disclosure relate to reserving resources in wireless communication systems, such as those employing listen before talk (LBT). The disclosed methods and apparatus employ a channel reservation preamble used in a sequence of burst or data packet transmissions. The preamble including a channel reservation indication is included in a first data packet transmitted from a first network node. The channel reservation indication is configured to indicate a transmission time reservation of channel resources covering the data packet containing the preamble, a second data packet to be received from a second network node responsive to the first data packet, and at least a portion of a third data packet transmitted from the first network node subsequent to the transmission of the second data packet. In this manner, over-reservation of channel resources is mitigated. Other aspects, embodiments, and features are also claimed and described.

摘要： Uplink short transmissions (ULSTs) may be configured in a wireless communications system to be transmitted in configured uplink resources within a listen-before-talk (LBT) frame or within a ULST window during which a user equipment (UE) may transmit a ULST and during which the base station may monitor for ULSTs. A UE having an amount of data to be transmitted that is less than a threshold value may transmit the data in the ULST, and avoid the need to have the base station allocate separate uplink resources outside of the configured uplink resources or the ULST window.
摘要翻译：可以在无线通信系统中配置上行链路短传输（ULST），以在先听后（LBT）帧内或在ULST窗口内的配置的上行链路资源中发送上行链路资源，在该ULST窗口期间，用户设备（UE）可以发送ULST，并且在此期间基站可以监视ULST。具有小于阈值的要发送的数据量的UE可以在ULST中发送数据，并且避免需要让基站在配置的上行链路资源或ULST窗口之外分配单独的上行链路资源。 / p>

摘要： Methods, systems, and devices are described for a system that supports wireless communication with a first set of devices using a first OFDM symbol duration associated with a first tone spacing (i.e., a first physical layer (PHY) configuration) and second set of devices using a PHY configuration associated with a second tone spacing. A base station may transmit a set of discovery reference signals (DRS) in a narrowband region of a primary channel of a carrier. The DRS may have the first PHY configuration and a secondary channel of the carrier may support communications using the second PHY configuration. The base station may transmit a first system information (SI) message for one set of devices using the first PHY configuration, and it may transmit a second SI message for another set of devices using the second PHY configuration.

摘要： Techniques are described for wireless communication. One method includes identifying a plurality of counters used to contend for access to a plurality of channels of an unlicensed radio frequency spectrum band. Each of the plurality of counters is associated with a respective channel of the plurality of channels of the unlicensed radio frequency spectrum band. The method also includes measuring at least one channel of the plurality of channels of the unlicensed radio frequency spectrum band. The measuring is associated with a contention for access to the at least one channel of the unlicensed radio frequency spectrum band. The method also includes synchronizing or desynchronizing at least a subset of the plurality of counters based at least in part on the measuring.

摘要： A base station or user equipment (UE) may manage scheduling of code blocks to be transmitted and manage memory interface usage to enhance memory read and write operations and provide for enhanced efficiency for decoding of retransmissions of code blocks. In some aspects, a base station or UE may identify an available throughput, or budget, for performing read and write operations to a memory. The base station or UE may then estimate an amount of read and write operations to be performed during a particular time period. In the event that the amount of read and write operations exceed the budget, scheduling of code blocks to be transmitted may be adjusted, one or more read or write operations may be skipped, or combinations thereof may be employed to achieve the memory read and write budget.

摘要： Additional improvements to the design of enhanced physical random access channel (ePRACH) procedures are disclosed for communications systems having contention-based shared spectrum including unlicensed frequency bands. The additional improvements address the uncertainty of transmission in listen before talk (LBT) -based communications and cooperation with other radio access technologies competing for the same frequency spectrum. An extended clear channel Assessment over multiple subframes is performed by the UE, during which in particular the presence of channel reserving signals, such as CUBS, is monitored. In case of eCCA/CCA success,, the actual type 2 random access preamble is transmitted, before the subframe resync boundary, or else on the following subframe if does not fit anymore.
