摘要： Methods and apparatus are provided for integrated communication and sensing. For example, an electronic device may transmit a radio frequency (RF) pulse signal in the active phase of a periodic sensing cycle, and sense in the passive phase of the sensing cycle, a reflection of the RF pulse signal reflected from an object. The RF pulse signal is defined by a waveform for carrying communication data between electronic devices. The sensed RF pulse signal is at least a portion of the transmitted or reflected RF pulse signal, wherein the portion is equal to or greater than a threshold value for the object being within a sensing range of the first electronic device. The electronic device may also receive a communication signal from another electronic device during the passive phase.

摘要： A system is provided for precoding in a coordinated multipoint (CoMP) joint transmission (JT) system. During operation, the system identifies, at a first base station (BS) of a first cell, a set of regular user equipments (UEs), which are located within the first cell and receive signals from the first BS; and one or more coordinated multipoint (CoMP) UEs, which are located within a second cell and receive signals. The CoMP UEs receive signals from both the first BS and a second BS of the second cell. The system obtains a first channel state information (CSI) associated with the regular UEs, receives a second CSI associated with the CoMP UEs from the second BS, and constructs a local precoder for the first cell in accordance with the first CSI and the second CSI.

摘要： In a wireless communication system, a base station assigns resources to mobile stations using indices. Each index is associated with an assignment schedule for assigning resources. Once the base station determines an assignment schedule to assign particular resources, it encodes the schedule into an index and transmits it. A mobile station receives the index and decodes it to recover the assignment schedule. Both the base station and the mobile station may use look-up tables and/or algorithms for storing or generating indices associated with assignment schedules. To assign resources so as to indicate transmission characteristics over the resources, the base station transmits assignment blocks. Each assignment block indicates original transmission, retransmission, persistent assignment, non-persistent assignment, HARQ signaling, RAS-HARQ signaling, DRCH assignment, and/or LRCH assignment.
