Embodiment Construction

[0036] figure 1 An exemplary cell 100 in a wireless communication system is shown. Cell 100 includes a plurality of user nodes 104-1 to 104-n and 110 connected to serving access node 102 via radio links 106-1 to 106-n and 108. For purposes of the description herein, user nodes 104 - 1 through 104 - n and 110 are generally referred to as user nodes 104 , while radio links 106 - 1 through 106 - n and 108 are referred to as radio links 106 .

[0037] The cell 100 may be based on any currently available wireless communication standard, such as Long Term Evolution (LTE), or may use future radio access technologies. The user nodes 104-1 to 104-n and 110 connected to the access node 102 may be any of various types of mobile communication devices, such as cell phones, smartphones, tablets, phablets, laptops, cars, etc. . Radio links 106-1 to 106-n and 108 are logical connections between each user node 104-1 to 104-n, 110 and the serving access node 102, and pass between the serving...

Abstract

An access node in a wireless communication system includes a transceiver and a processor. The transceiver is configured to receive one or more uplink pilots associated with a user node via a radio link. The processor is configured to determine a location of the user node and whether the radio link is a line-of-sight radio link or a non-line-of-sight radio link based on the one or more uplink pilots. When the radio link is a line-of-sight radio link, the processor determines a location-based precoding vector based on the location of the user node, and generates a precoded vector based on the determined location-based precoding vector. Encoded downlink control signals. The transceiver sends the precoded downlink control signal to the user node.

Description

technical field [0001] Aspects of the present disclosure relate generally to wireless communications, and more particularly to exchanging control information between nodes in a wireless communications network. Background technique [0002] The number of mobile devices or user nodes requesting services from wireless communication systems is expected to increase dramatically in the coming years, and the amount of control information used to coordinate and control these user nodes will increase proportionally. A control channel is a predetermined or agreed radio resource for exchanging control information, which reduces the radio resources available for data transmission. Accordingly, it is desirable to optimize or minimize the amount of radio resources used for control information within a wireless communication network. [0003] Conventional wireless communication systems based on current standards such as Long Term Evolution (LTE) employ non-precoded control channels. This...
