    摘要: A communication is provided that schedules both Distributed Virtual Resource Blocks (DVRB) and Localized Virtual Resource Blocks (LVRB) in a same frequency channel, thereby obtaining the benefits of frequency selective scheduling while minimizing the uplink feedback overhead. In one embodiment of the invention, the communication system assigns one or more downlink Physical Resource Blocks (PRBs) of multiple downlink Physical Resource Blocks (PRBs) to each user equipment (UE) given an LVRB to produce at least one reserved PRB and multiple non-reserved PRBs and assigns a part of each PRB of the multiple non-reserved PRBs to a UE given a DVRB. In another embodiment of the invention, the communication system assigns PRBs pre-reserved for localized transmission to UEs scheduled for LVRBs and assigns parts of multiple PRBs pre-reserved for distributed transmission to each UE given a DVRB.

    摘要: Various embodiments are described which can serve to mitigate interference between the control channel signaling of adjacent sectors/cells. Potentially, these techniques may have the benefit of reducing the system resource drain caused by control channels, particularly control channels in high frequency-reuse, OFDMA systems. A transmitting device (101) transmits primary control channel information to a plurality of user devices (102). The primary control channel information includes an indication that a first OFDMA resource region (e.g., 320 or 330) is assigned to at least one user device of the plurality of user devices. The transmitting device correspondingly transmits secondary control channel information to the at least one user device using the first OFDMA resource region.

    摘要: A network node constructs (22) a downlink transmission using at least one group of resource elements. A remote unit receives (12) the downlink transmission and determines (13) a lowest index of the at least one group of resource elements. The remote unit then determines (14) an uplink resource, for use in uplink (UL) acknowledgment signaling, using the lowest index. The network node then receives (23, 24) the UL acknowledgment signaling that corresponds to the downlink transmission, the UL acknowledgment signaling having been transmitted using the uplink resource based on the lowest index. To determine the uplink resource, both the remote unit and the network node implicitly use the lowest index of the at least one group of resource elements that were used to construct the downlink transmission. Implicitly determining the uplink resource in this manner, serves to reduce overhead related to acknowledgment signaling.
