Abstract: A first precoding matrix W1 is selected from a first codebook comprising sets of rank specific precoding matrices. The first codebook is characterized by there being fewer precoding matrices associated with higher ranks than associated with lower ranks, and characterized by precoding matrices associated with ranks above a certain rank all being diagonal matrices. The selected first precoding matrix W1 is used to select a rank-specific second precoding matrix W2 from a second codebook, such that the selected first and second precoding matrices form a joint precoder specific to a desired rank. The second codebook is characterized by differently sized precoding matrices associated with each of N total ranks, in which N is an integer greater than one. Information on the joint precoder is reported to a network node over an uplink transmission channel.

Abstract: A user's downlink component carriers DL-CCs are divided into groups. An aperiodic CQI/PMI report is triggered by signaling (for example one bit). There is a pattern that maps the signaled trigger to a particular DL-CC within a group of DL-CCs that are configured for a user equipment UE, and that mapped particular DL-CC is determined to be the subject of the aperiodic report. In various embodiments the pattern is implicit and points to the DL-CC for which an aperiodic report has not been sent for more than a threshold time interval; or to the DL-CC for which resources have not been allocated for a periodic report; or to every DL-CC in the group that are activated for the user equipment. Examples are detailed for apparatus, method and computer program from the perspective of the network and from the perspective of the UE.

Abstract: A persistent or a semi-persistent uplink resource allocation also includes an indication for a user equipment UE to send channel quality reports. The format for the channel quality report is determined (based on a transmission mode for which the UE receives a downlink shared channel). In at least first transmissions of user data for instances of the persistently allocated uplink resource the UE sends user data and a channel quality report according to the determined format. For the case that a NACK is received in reply to one of those sent user data with channel quality reports, four options are detailed: re-send the NACK'd user data on a next instance of the persistently allocated UL resource with or without a channel quality report, and re-send the NACK'd user data on a dynamically allocated uplink resource with or without a channel quality report.

Abstract: An apparatus and method for wireless devices have a scalable bandwidth allocation for operating in different bands at different data rates and provide interference prevention between co-existing modes of operation. MAC frame logic selectively defines first characteristics of a first operational mode corresponding to a first wireless link type and second characteristics of a second operational mode corresponding to a second wireless link type. A transceiver coupled to the MAC frame logic communicates, in response to the MAC frame specification, a first protocol data unit for the first operational mode having the first characteristics for the first wireless link type and a second protocol data unit for the second operational mode having the second characteristics for the second wireless link type. Interference detecting logic detects interference conditions in the first wireless link type and allocates suitable areas for operation of the second wireless link.
