Problems solved by technology

However, this dynamic switching may lead to interference between neighboring cells that have consistent downlink / uplink communication (i.e. the same subframes in neighboring cells are configured for downlink or configured for uplink) and subframes configured for inconsistent downlink / uplink communication (i.e. the same subframe in neighboring cells is configured for communication in different directions) frequently switch between

Embodiment Construction

[0021] Various aspects are now described with reference to the figures. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that these aspects may be practiced without these specific details.

[0022] Described herein are various aspects related to using a modified subframe structure when communicating between network nodes. The modified subframe structure may be modified from a legacy subframe structure that may be configured for one type of communication (eg, downlink or uplink) across the subframe. For example, a modified subframe structure may include a first portion (e.g., of one or more blank symbols) for monitoring communications from neighboring network nodes, and a first portion (e.g., of one or more blank symbols) for transmitting control information or data. the second part of the number of remaining symbols. As mentioned...

Abstract

The present disclosure provides methods, apparatuses, and computer-readable storage media for determining subframe configurations in wireless communications. A modified subframe structure is defined for a subset of the plurality of subframes. The modified subframe structure includes a first portion with one or more blank symbols on which a network node can measure monitoring to determine whether a subframe is used by a neighboring network node as a downlink (or uplink) subframe. The modified subframe structure may also include a second part of symbols in the subframe for transmitting control information or data, which may be based on determining whether the subframe is used by a neighboring network node for downlink (or uplink) subframe. This can reduce the impact of possible interference caused by a network node dynamically switching time division duplex (TDD) subframe configurations by enabling the network node to determine when a neighboring node is transmitting in a subframe and respond accordingly Avoid sending in this subframe.

Description

[0001] Claiming priority under 35 U.S.C. §119 [0002] This patent application claims priority from nonprovisional application No. 15 / 239,192, filed August 17, 2016, entitled "TECHNIQUESFOR WIRELESS COMMUNICATIONS USING A MODIFIED SUBFRAME STRUCTURE," and filed September 25, 2015 , Provisional Application No. 62 / 232,970 entitled "TECHNIQUES FOR WIRELESS COMMUNICATIONS USING A MODIFIED SUBFRAME STRUCTURE", both of which have been assigned to the assignee of the present application and are hereby expressly incorporated by reference to for all purposes. technical field [0003] The present disclosure relates to the field of wireless communication, and more particularly, the present disclosure relates to techniques for wireless communication using a modified subframe structure. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, data, and so on. These systems may be multiple-access sy...
