Embodiment Construction

[0051] In order to make the objects, technical solutions, and advantages of the present application, the present application will be described in conjunction with the specific examples and corresponding drawings of the present application. Obviously, the described embodiments are merely the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative labor premises.

[0052]Multi-beam (ie, TRP) of uplink data repeatedly transmitted (pattern) should have sufficient flexibility to configure, to vary in the beam direction of the movement of the terminal and the rotation of the terminal in the case of high frequency bands. To achieve this, the idea of ​​this application is that two SRS resource sets are sent for multi TRP PUSCH, each resource collection contains one or more resources, select SRS resources through Mac CE signaling. For e...

Abstract

The invention discloses a multipoint uplink data grant-free scheduling transmission method and equipment. The method comprises the following steps: a high-level signaling RRC comprises two groups of SRS resource indications which are used for configuring two SRS resource sets, wherein each set comprises one or more SRS resources, each SRS resource set is associated with a TRP, and the physical layer MAC CE signaling is used for specifying a first SRS resource in the first group of SRS resource sets and specifying a second SRS resource in the second group of SRS resource sets; and determining a TRP mapping mode through at least one of the high-level signaling, the MAC CE signaling and the dynamic downlink control signaling. The equipment is used for implementing the method. According to the invention, the problem of inflexible uplink data transmission resource configuration of the mobile terminal under the multi-TRP condition is solved.

Description

Technical field [0001] The present application relates to the field of mobile communication, and more particularly to a method and apparatus for uplink data transmission. Background technique [0002] NR supports two types of uplink-free transmission, one is all of the high-level parameter configurations including time frequency domain resources, demodulation reference signals, open-loop function control, modulation coding schemes, waveforms, redundant versions, and repetitions. Transmission parameters. After the terminal receives the high-level parameters, the configured transmission parameters can be used to perform uplink data transmission on the configured time-frequency resources, and the other is the first high-level signaling configuration including the period, open-loop function, waveform, and Transfer resources and parameters in redundant versions, number of repetitions, and then use CS-RNTI scrambled DCI to activate second types of PUSCH transfers based on configuration...
