Abstract: Techniques for channel selection in a shared communication medium are disclosed. A communication apparatus may include one or more transceivers, a processor, and memory coupled to the processor and configured to store data and/or instructions. The one or more transceivers may be configured to monitor signaling on a plurality of available channels associated with a communication medium.

Abstract: Techniques for managing access to a shared communication medium are disclosed. Scheduling grants may be sent to different access terminals for different sets of resources for uplink transmission on the communication medium. A series of re-contention gaps may be scheduled for access terminal contention within or between the different sets of resources. Uplink and downlink transmission on the communication medium may be silenced during each of the series of re-contention gaps. Moreover, an access terminal may receive a scheduling grant that allocates a set of resources to the access terminal for uplink transmission on a communication medium and contend for access to the communication medium based on the scheduling grant. The access terminal may then selectively transmit uplink traffic over the allocated set of resources based on the contending.

Abstract: Techniques for managing re-contention on a shared communication medium are disclosed. In order to facilitate re-contending for access to the communication medium, an access point may adjust one or more uplink transmission parameters associated with a triggering condition for invoking a contention timer. In addition or as an alternative, the access point may mute transmission on the communication medium during one or more symbol periods designated for transmission. In addition or as an alternative, the access point may configure a timing advance to create a re-contention gap.

Abstract: A method of wireless communication includes adjusting a channel quality indicator (CQI) to compensate for coexistence interference experienced between communication resources (such as an LTE radio and a Bluetooth radio). The CQI may be set to zero, falsely indicating to a serving enhanced NodeB that a UE is out of range, thereby creating a gap in LTE operation that may be used by an alternate radio access technology. To compensate for fluctuating interference, the CQI may be adjusted to incorporate average coexistence interference over a period of time. Alternatively, the CQI at a time may incorporate coexistence interference regardless of whether interference is experienced at that specific time. A CQI value may also be boosted to compensate for a CQI backoff. CQI may be adjusted to avoid a spiral of death effect.

Abstract translation: 一种无线通信方法包括调整信道质量指示符（CQI）以补偿通信资源（例如LTE无线电和蓝牙无线电）之间经历的共存干扰。 CQI可以被设置为零，向服务增强型节点B虚拟地指示UE超出范围，从而在可能由替代无线电接入技术使用的LTE操作中产生间隙。 为了补偿波动的干扰，可以调整CQI以在一段时间内并入平均共存干扰。 或者，无论在该特定时间是否经历干扰，一次的CQI可以并入共存干扰。 还可以提升CQI值以补偿CQI回退。 可以调整CQI以避免死亡效应的螺旋。

Abstract: Techniques for managing operation over a communication medium shared between Radio Access Technologies (RATs) are disclosed. In one example, one or more parameters of a Time Division Multiplexing (TDM) communication pattern may be set to define activated periods and deactivated periods for communication over the medium. A first interlace may be selected among a plurality of interlaces for communication over the medium, the first interlace being reserved for a first operator. During the first interlace, transmission over the medium may be cycled in accordance with the TDM communication pattern, and deactivated during a second interlace among the plurality of interlaces that is reserved for a second operator.

Abstract: Techniques to more efficiently transmit pilot and signaling on the uplink in an OFDM system. With subband multiplexing, M usable subbands in the system are partitioned into Q disjoint groups of subbands. Each subband group may be assigned to a different terminal for uplink pilot transmission. Multiple terminals may transmit simultaneously on their assigned subbands. The transmit power for the pilot may be scaled higher to attain the same total pilot energy even though S instead of M subbands are used for pilot transmission by each terminal. Pilot transmissions from the terminals are received, and a channel estimate is derived for each terminal based on the pilot received on the assigned subbands. The channel estimate comprises a response for additional subbands not included in the assigned group. Subband multiplexing may also be used for uplink signaling transmission.
