The method may also include transmitting and/or receiving the control information on a physical uplink control channel and a control only physical uplink shared channel, or only on the control only physical uplink shared channel.

Abstract: A wireless communication system and a method for detecting downlink receiving power in the system are disclosed. N cells in the system respectively transmit data to at least one receiving terminal via N resource blocks using the same time-frequency resources; multiple channel state information reference signals (CSI-RSs) of a corresponding cell are set in each resource block, and orthogonality is maintained among the CSI-RSs of all the cells, wherein N is an integer greater than 1. Said method includes: an additional demodulation reference signal (DM-RS) used for indicating a receiving power is set in a puncture position in the resource block of the first cell which corresponds to a CSI-RS set in a resource block of another cell; and the receiving power of said first cell is detected according to said additional DM-RS. By using said method, the receiving power of a single cell in N cells can be detected, and the system overhead is not increased.

Abstract: A macro eNB (MeNB) triggers a small cell (eLA eNB) to transmit a sequence on a second frequency band using a triggering command that indicates a time to transmit the sequence. On a first frequency band the MeNB triggers at least one user equipment UE to detect the sequence on the second band, and this trigger also has a first indication of when the sequence will be transmitted. From a second indication the MeNB receives on the first band from the at least one UE in response to the triggering of the UE the MeNB can determine whether the UE is located proximate to the small cell. The indication may be as little as a single bit indicating whether the UE detected or not the sequence. The first and second bands may be on first and second component carriers that may not be synchronized to one another, and the aperiodic nature of the triggered sequences and detection reports saves UE power.

Abstract: A job may be divided into multiple tasks that may execute in parallel on one or more compute nodes. The tasks executing on the same compute node may be coordinated using barrier synchronization. However, to perform barrier synchronization, the tasks use (or attach) to a barrier synchronization register which establishes a common checkpoint for each of the tasks. A leader task may use a shared memory region to publish to follower tasks the location of the barrier synchronization register—i.e., a barrier synchronization register ID. The follower tasks may then monitor the shared memory to determine the barrier synchronization register ID. The leader task may also use a count to ensure all the tasks attach to the BSR. This advantageously avoids any task-to-task communication which may reduce overhead and improve performance.
