    • A system and method of signal transmission in a wireless communications network is disclosed. A coordinated transmission is transmitted from a plurality of base stations, each including a transmission point. Each transmission point is configured to transmit a cell specific reference signal in a particular set of resource elements. Additionally, a determination is made regarding which of the plurality of base stations will serve as a lead base station in the coordinated transmission and data is mapped to all available resource elements in a physical resource block, except the resource elements in which the lead base station is configured to transmit a cell- specific reference signal. Further, each remaining base station is instructed to mute transmissions in the particular set of resource elements in which the corresponding transmission point is configured to transmit a cell specific reference signal.

    • A scheme for the transmission and reception of downlink control channel messages in LTE which can be applied in association with random access transmission (RACH) in the uplink. Initially, the UE monitors a specific search space on the downlink control channel (PDCCH) for specific types of message (DCI messages) from the eNodeB following a RACH transmission. Subsequently (112 - 120) the UE is configured to monitor a different search space and/or control channel (e.g. E-PDCCH) for the same type of DCI message. The UE then proceeds (122) to monitor the different search space and/or control channel. Allowing DCI messages to be transmitted on the E-PDCCH rather than the PDCCH reduces the loading on PDCCH and improves control channel efficiency (in terms of resource use). In the case of RACH, this raises the limit on the rate at which random access transmissions can be processed. The potential increase in total number of blind decodings required to receive the E-PDCCH may be mitigated by means of limiting the duration of monitoring the E- PDCCH to subframes where the expected DCI messages may be transmitted by the network.
    • 用于在LTE中发送和接收下行链路控制信道消息的方案,其可以在上行链路中与随机接入传输(RACH)相关联地应用。 首先,在RACH传输之后,UE监视来自eNodeB的特定类型消息(DCI消息)的下行链路控制信道(PDCCH)上的特定搜索空间。 随后(112-120),UE被配置为监视相同类型的DCI消息的不同搜索空间和/或控制信道(例如E-PDCCH)。 然后,UE继续(122)以监视不同的搜索空间和/或控制信道。 允许在E-PDCCH而不是PDCCH上发送DCI消息减少PDCCH上的负载,并提高控制信道效率(在资源使用方面)。 在RACH的情况下,这提高了可以处理随机接入传输速率的限制。 可以通过将监视E-PDCCH的持续时间限制为网络可能发送预期的DCI消息的子帧来减轻接收E-PDCCH所需的盲解码总数的潜在增加。
