Embodiment Construction

[0193] Generally, in an LTE CA system, the number of simultaneous uplink carriers supported by a UE is limited. According to the characteristics of the limited uplink transmission capability, at the same time, in order to obtain the above-mentioned figure 2 For the downlink channel characteristics of the remaining three carriers, it may be considered to configure multiple uplink carriers for simultaneous transmission for the UE. The number of configured multiple uplink carriers exceeds the maximum number of simultaneous uplink carriers supported by the UE, and then the UE follows The SRS is sent on different uplink carriers in a time-division manner, so that the uplink transmission capability of the UE is not exceeded at the time of transmission, such as image 3 It is shown that at time 1, SRS is transmitted on carrier 1 and carrier 2; at time 2, SRS is transmitted on carrier 3 and carrier 4.

[0194] If no uplink data is sent on the uplink subframes of carrier 3 and carrie...

Abstract

The invention relates to wireless communication, in particular to terminal equipment, network equipment, an uplink sending method and an uplink receiving method, and aims to solve the problem that information such as downlink channel characteristics of carriers which do not send uplink reference signals cannot be obtained in a carrier aggregation scene. In the terminal equipment, a processing module selects one or more common carriers or special carriers from a first carrier set for an uplink subframe, and the first carrier set is composed of all carriers aggregated by carriers used by the terminal device for sending the first uplink subframe; and a sending module which gives up the sending of the uplink sub-frame on the one or more carriers. Wherein the special carrier is a carrier that the terminal device does not send uplink data or uplink control information in the uplink; wherein the common carrier is a carrier used by the terminal device for sending uplink data and / or uplink control information. By abandoning one uplink sub-frame on a part of carriers, the problem that information such as downlink channel characteristics and the like of carriers which do not send uplink reference signals cannot be obtained is solved.

Description

[0001] This application is a divisional application of the original application with the application number "201580065483.6" submitted on September 23, 2015, wherein the original application is incorporated in this application by reference. technical field [0002] The present invention relates to wireless communication technology, in particular to terminal equipment, network equipment, uplink sending method and uplink receiving method. Background technique [0003] During the evolution of the Long Term Evolution (LTE) protocol, the carrier aggregation (Carrier Aggregation, CA) technology was introduced in Release (R) 10, which allows the user equipment (User Equipment, UE) send and receive data. A network device such as an evolved NodeB (evolved NodeB, eNB) selects a cell as a primary cell (Primary Cell, Pcell) of the UE, and cells on other carriers are used as secondary cells (Secondary Cell, Scell) of the UE. A UE can send and receive data on the aggregated multiple cell...
