摘要： A user equipment (UE) conducting machine-type communication (MTC) attempts to blindly decode a message it received using a pre-arranged and finite set of transport formats; and sends on an uplink radio resource feedback about the message, wherein the feedback is based on a result of the blind decoding. Each transport format of the pre-arranged set comprises a unique combination of modulation and coding scheme, physical resource block set;, and number of transmit repetitions. Prior to the message the pre-arranged set may be indicated to the UE in wireless signaling, or it may be specified in a radio standard. The set may be designated for downlink messages and a second set designated for uplink messages. Various embodiments are described for the uplink radio resource on which the feedback is sent, and conventional HARQ feedback is adapted for MTC in these teachings.

摘要： A user equipment UE determines at least one first set SI of physical resource blocks PRBs, and detects downlink signaling within search spaces of set(s) SI. Through that downlink signaling the UE obtains a configuration for a downlink control channel, and that configuration indicates at least one second set S2 of PRBs and at least one search space specific for the UE which lies within S2. The UE utilizes the obtained configuration to monitor at least some of the search spaces of SI and the at least one search space specific for the UE of S2 for further downlink control signaling. Multiple implementations are detailed for how the UE gets SI. This invention is particularly useful for a configurable ePDCCH region in a stand-alone carrier where the UE is not able to get the new configuration from some other carrier such as a PCell whose configuration does not change.

摘要： There is a predefined mapping of antenna ports to radio resources (REs/REGs/CCEs). An antenna port configuration for a user equipment (UE) is selected from among multiple predefined configurations each having two antenna ports. Each of the radio resources which map from at least one antenna port of the selected configuration are identified according to the predefined mapping to define a search space consisting of the identified radio resources in each physical resource block pair set that is assigned to the UE. The network transmits a control channel to the UE within the defined search space using the antenna ports of the selected configuration. The UE confines its blind search for the control channel to the defined search space and to the antenna ports of the selected configuration. The examples have the control channel as ePDCCH and show that both distributed and localized ePDCCH can be multiplexed even to the same PRB pair set.

摘要： Embodiments include a method for physical layer transmission in a network equipment comprising receiving, from a higher layer, messages to be transmitted during a subframe on one or more control channels; determining the number of elements required (i.e., aggregation level) for each control channel; allocating a plurality of physical resource blocks (PRBs) for transmitting the control channels and partitioning the PRBs into clusters; determining the interleaving depth (IDP) for each cluster; mapping each element to a cluster according to the IDP for that cluster; and generating a transmission signal comprising the clusters. In some embodiments, the IDP for each cluster is linearly related to the number of PRBs comprising that cluster, e.g., identical to the number of PRBs in that cluster. In some embodiments, the IDP for each cluster is related to the cluster index. Embodiments include network equipment and computer-readable media embodying one or more of the methods.

摘要： A user equipment determines(302) from a received downlink resource allocation that an uplink data channel is reconfigured for multi-cell periodic feedback of channel state information. In response, the UE utilises (306) at least a first and a second instance of the uplink data channel to send the multi-cell periodic feedback of the channel state information. Four different triggering mechanisms (304) are disclosed by which the UE determines the reconfiguration. The UE can detect a predetermined combination of at least two fields of the resource allocation; or a value of a channel state indication request state in the resource allocation; or a predefined sequence in a field of the resource allocation; or by de-scrambling at least a portion of the resource allocation using a temporary identifier dedicated for this purpose.

摘要： A method, apparatus and computer program product are provided to provide improved uplink control signaling so as to reduce downlink throughput loss. In the context of a method, the acknowledgement/negative acknowledgement (A/N) bits and channel state information (CSI) bits may be encoded utilizing two or more encoders. The number of encoders that are utilized is dependent on a number of bits to be encoded. The method may also rate match the encoded A/N bits and encoded CSI bits. At least one of the encoding and the rate matching is performed in accordance with a coding rate defined by a ratio γ of a coding rate of the A/N bits and a coding rate of the CSI bits. The method may also interleave the encoded A/N bits and the encoded CSI bits following the rate matching.
