example 1

[0102] Example 1: time domain (time domain) indication information and frequency domain (frequency domain) indication information are jointly encoded.

[0103] Wherein, the time domain indication information is the offset (offset) between the uplink transmission cancellation indication (UL CI) signaling and the time slot (slot) or symbol (symbol) to be canceled (cancel); the frequency domain indication information is the current uplink transmission bandwidth Part (UL BWP) of a subset.

[0104] In Example 1, there are many different combinations of the jointly coded time-domain indication information and frequency-domain indication information, and the largest set S of the different combination modes is set max , the largest set S max The number of combinations is M, and M can be predefined or configured.

[0105] For example, the base station can configure the maximum set S of combinations of time domain indication information and frequency domain indication information for ...

example 2

[0109] Example 2: Joint encoding of time domain indication information and frequency domain indication information.

[0110] Wherein, the time domain indication information is the offset between the UL CI signaling and the reference time region (reference time region), and the offset between the start time of the reference time region and the time slot or symbol to be canceled; the frequency domain indication information is the current A subset of the upstream transmission bandwidth section.

[0111] In example 2, there are many different combinations of the jointly coded time-domain indication information and frequency-domain indication information, and the largest set S of the different combination modes is set max , the largest set S max The number of combinations is M, and M can be predefined or configured.

[0112] For example, the base station can configure the UE with the largest set S of combinations of jointly coded time domain indication information and frequency d...

example 3

[0117] Example 3: Joint encoding of time domain indication information and frequency domain indication information.

[0118] Wherein, the indication information in the time domain is the offset between the start time of the reference time region (reference time region) and the time slot or symbol to be canceled; the indication information in the frequency domain is a subset of the current UL BWP.

[0119] In example 3, there are many different combinations of the jointly coded time domain indication information and frequency domain indication information, and the largest set S of the different combination modes is set max , the largest set S max The number of combinations is M, and M can be predefined or configured.

[0120] For example, the base station can configure the UE with the largest set S of combinations of jointly coded time domain indication information and frequency domain indication information through radio resource control (Radio Resource Control, RRC). max A ...

Abstract

Provided in an embodiment of the present invention are a method for transmitting an uplink transmission cancel signaling, a network side device and a user equipment, the method comprising: jointly encoding time domain indication information and / or frequency domain indication information in the uplink transmission cancel signaling to obtain an encoding result; and sending the uplink transmission cancel signaling to one or more pieces of UE, wherein the uplink transmission cancel signaling comprises the coding result. Thus, the time domain indication information and / or the frequency domain indication information in the uplink transmission cancel signaling are jointly encoded, and signaling overhead is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a transmission method for uplink transmission cancellation signaling, network side equipment and user equipment. Background technique [0002] Compared with previous mobile communication systems, the future fifth-generation communication technology (fifth-generation, 5G) system needs to adapt to more diverse scenarios and business requirements. For example, the main scenarios of New Radio (NR) include: Enhanced Mobile Broadband (Enhance Mobile Broadband, eMBB), Massive Machine Type Communication (Massive Machine Type Communication, mMTC), ultra-reliable and low-latency communication (Ultra Reliable&Low Latency Communication, URLLC), these scenarios put forward high reliability, low latency, large bandwidth, wide coverage and other requirements for the system. [0003] When the eMBB service and the URLLC service need to be multiplexed, there...
