Embodiments of apparatus and methods for signaling for resource allocation and scheduling in 5G-NR integrated access and backhaul are generally described herein. In some embodiments, User Equipment configured for reporting a channel quality indicator (CQI) index in a channel state information (CSI) reference resource assumes a physical resource block (PRB) bundling size of two PRBs to derive the CQI index.

Signaling for resource allocation and scheduling in 5G-NR integrated access and backhaul

Embodiments of quasi-orthogonal space-time encoder, decoder and method for space-time encoding and decoding orthogonal frequency division multiplexed (OFDM) signals in a multiple-input multiple-output (MDMO) system are generally described herein. Other embodiments may be described and claimed. In some embodiments, a method of decoding received multicarrier signals comprises deriving objective functions from a received signal matrix, minimizing the objective functions to generate decoded hard bits, and solving a set of linear equations of the objective functions to generate decoded soft bits.

Quasi-orthogonal space-time block encoder, decoder and methods for space-time encoding and decoding orthogonal frequency division multiplexed signals in a multiple-input multiple-output system

An efficient channel quality indicator channel (CQICH) transport method and system are disclosed. The CQICH transport method defines five types of CQI transport formats, to cover known cases of CQI feedback. The CQICH transport method further defines the format of transportation, which enables any of the five types of CQI transport formats to be transmitted.

Efficient CQICH transport format

A beam selection method in open loop MU-MIMO is disclosed, for an asymmetric antenna configuration. The proposed beam selection method employs limited feedback, as compared with single-user closed-loop MIMO and multiple-user closed-loop MIMO, in which the base station requires channel state information (CSI). The multi-user MIMO beam selection method selects the portion of beams from candidate beams for data transmission, meaning that the base station is training M beams. From this, the subscriber station selects N beams from the total M beams, with N&#x2266;M.

Embodiments of methods and apparatus for a multiuser sector micro diversity system are described herein. Other embodiments may be described and claimed.

Multiuser sector micro diversity system

A base station is capable of unifying a single-user MIMO scheme with a multi-user MIMO scheme by receiving a Rank-1 CQI values from one or more subscriber stations. The base station also receives preceding vectors from the subscriber stations, and then determines which of the subscriber stations has a best Rank-1 CQI value. The base station then determines a beam forming matrix to use based at least in part on the vectors received from the subscriber station having the best Rank-1 CQI value. The base station then broadcasts data to the subscriber station using the beam forming matrix corresponding to the subscriber station having the best Rank-1 channel quality indicator to implement single-user MIMO in one or multiple streams to that subscriber station, or to the subscriber stations having the best Rank-2 channel quality indicators to implement multi-user MIMO in multiple streams.

Machine-readable media, methods, apparatus and system for scheduling transmissions in a wireless communication system are described. In some embodiments, a base station may comprise a network interface device to receive and process a long-term signal to interference plus noise ratio (SINR) and a channel quality indicator (CQI) from each subscriber station of a plurality of subscriber stations; a reference signal to interference plus noise ratio determining logic to determine a reference signal to interference plus noise ratio (Ref_SINR) for the each subscriber station; and a target fairness factor determining logic to determine a target fairness factor (TFF) for the each subscriber station; a real fairness factor determining logic to determine a real fairness factor (RFF) for the each subscriber station; and a pseudo CQI calculating logic to calculate a pseudo CQI for the each subscriber station based at least in part on the CQI, SINR, Ref_SINR, TFF and RFF.

Machine-readable media, methods, apparatus and system for allocating power in a MU-MIMO communicating system are described. In some embodiments, an apparatus of a base station in the MU-MIMO communication system may comprise: a power calculating logic to calculate a power for each user of a plurality of users communicating with the base station in the MU-MIMO system, based upon an average power and a power increment. The power calculating logic may further comprise an average power logic to calculate the average power among the plurality of users based upon a total power for the base station to communicate with the plurality of users, and a power increment logic to determine the power increment for the each user based upon at least one of a fairness algorithm and a throughput algorithm, and wherein different users of the plurality of users having different long-term signal to interference plus noise ratios (SINRs) are calculated with different powers. The apparatus may further comprise a power allocating logic to allocate the power to the each user.

Method and apparatus for allocating power in a MU-MIMO communication system

A unified open loop single-user/multiple-user multiple-input-multiple-output (MIMO) system and method are disclosed. The system and method operate without use of channel state information feedback. Instead, the method utilizes channel quality indicator feedback to schedule users to spatial resource blocks. Both symmetric multi-user MIMO schemes (like 2&#xd7;2 and 4&#xd7;4) and asymmetric multi-user MIMO schemes are considered. CQI feedback and reduction proposals are also introduced. The method may be used in a proposed network topology.
