摘要:
A method for performing measurement by a radio apparatus is presented. In one embodiment, the method includes determining raw measurements (e.g., a channel estimation and a noise variance estimation) of a subband and determining a rank indicator (RI) without requiring a precoding matrix indicator (PMI) search. The method includes calculating, based at least on the raw measurements, a mean instantaneous capacity (MIC) for the subband and determining a channel quality indicator (CQI) and a PMI based at least on the MIC. In one embodiment, the method uses subband-based measurements for performing feedback/measurement.

A method and system of reducing false detection of control channel messages in a wireless communication system. This facilitates blind detection of control channel messages in the wireless communication network. In one embodiment of the invention, the control messages in the wireless communication system are randomized or scrambled to minimize or lower the probability of false detection of the control channel messages. The control channel message includes, but is not limited to, an Assignment Advanced Media Access Protocol (A-A-MAP) Information Element (IE) and the like. In one embodiment of the invention, the contents of the A-A-MAP IE are randomized or scrambled before encoding into A-A-MAP symbols.

An enhanced semi-explicit solution for HARQ feedback channel indexing in wireless communication systems is disclosed. The HARQ feedback channel indexing method may be applied to the HARQ feedback channel transmitted in the downlink, as well as the HARQ feedback channel transmitted in the uplink.
摘要:
Techniques for use in a blind detection process of information elements. Channels can be allocated into groups. For each group, resource blocks of each channel can be further divided into subspaces. A base station may communicate a number of channels in a group, a number of subspaces allocated to a group of channels, and a bit shift value to all mobile stations via non-specific user channels to a mobile station. The mobile station uses a blind detection scheme and the number of channels allocated per group, a number of sub-spaces per group of channels, and a bit shift value to locate an information element assigned to the mobile station. A number of blind detection trials may be capped to a sum of a number of channels for all allocated groups.

摘要:
A User Equipment and an eNodeB system are configured for performing interference mitigation in the UE. Input circuitry in the wireless communication device receives an OFDM downlink channel signal associated with a serving cell and receives downlink control information for an interfering cell. The downlink control information is used by the UE to perform channel estimation for the interfering cell. An interference mitigation module is provided for calculating an interference-mitigated version of the received channel signal using estimated channel transfer functions for both the serving cell and the interfering cell, power control parameters and using set of modulation constellation points corresponding to the OFDM downlink channel. Other embodiments may be described and claimed.

An embodiment of the present invention provides a method of improving subcarrier permutation to achieve high frequency diversity of OFDMA systems in wireless networks, comprising introducing different tone selections for different symbols, such that if a channel has only a few tones in each symbol of a resource unit it can still have sufficient frequency diversity.

Group size indications may be distributed from a base station to a mobile station in the form of assignment-advanced-MAP transmit control signaling. The signaling control information may be sent to a station, such as a mobile station, using a table that indicates the size of a group based on coding rates, such as one-half and one-quarter coding rates. Waste may be controlled by determining a size based on using an unoccupied resource in a group that is adjacent to data resource for data transmission by the station. However, an unoccupied resource in a group that is not adjacent to a data resource is not used for data transmission and is, therefore, wasted.
