摘要： Methods and apparatuses for providing adaptive search space definitions for wireless communications are provided where a code rate available for at least one selected downlink control information format is determined based on a determined control channel element size and an evaluation is performed whether said code rate is acceptable for transmission of control information. When said code rate is acceptable, at least one search space candidate is defined based on said control channel element size and code rate. When said code rate is unacceptable, iterative evaluation is provided whether a code rate determined on a higher aggregation level is acceptable.

摘要： A network access node/eNB selects one or more feedback modes for each of a plurality of channel state information reference signal CSI-RS resources so as not to exceed a predetermined maximum complexity; then configures a user equipment UE with them. Each CSI-RS resource is associated with a respective set of allowed feedback modes, and at least one of the sets has a fewer number of feedback modes than at least one other of the sets; for example the most complex feedback mode out of all possible feedback modes is excluded from the smaller set(s). An example formula is given for the predetermined complexity. If the UE receives a configuration that a) exceeds the maximum complexity, or b) configures a feedback mode for a given CSI-RS resource that is not in the respective associated set of allowed feedback modes, the UE can disregard the configuration as an error case.

摘要： A network signals an allocation (PDCCH) for a downlink shared channel (PDSCH); and also signals an indication (reference signal RS) whether a resource block (PRB) comprising the allocated downlink shared channel is used for a control channel transmission (E-PDCCH). Examples include the E-PDCCH being time or frequency multiplexed with the PDSCH; and the indication being a different RS sequence (at least one element being phase shifted) than an original RS sequence used if the PRB were not used for the E-PDCCH. The UE tests for the phase shift by blind decoding. If the phase shift is present the UE a) decodes a portion of the PRB for data if the network is using TDM for its E-PDCCH/PDSCH multiplexing, or b) decodes the full PRB only for the E-PDCCH if the network is using FDM for its E-PDCCH/PDSCH multiplexing.
