example 1

[0241] For example, four SSBs (SSB 0 to SSB 3) are associated with one PRACH Occasion (for example, RO 0), and one SSB corresponds to four Preambles (that is, preambles). The number of SSBs associated with a PUO is 2. The PUSCH resource unit is DMRS, and the number is 8.

Embodiment approach 1

[0242] Embodiment 1: The DMRS of the PUO is associated with the Preamble in the order of the Preamble first and then the SSB, and multiple consecutive DMRSs are associated with different SSBs.

[0243] For example, the DMRS of the PUO is first mapped to the Preambles corresponding to the two SSBs according to the numbering sequence of the Preambles, and then mapped according to the numbering sequence of the SSBs, and the mapping interval of the SSBs is V=1.

[0244] For another example, the Preamble of the SSB is associated with the DMRS of the PUO in the order of the PUSCH resource unit first and then the PUO, and multiple consecutive DMRS are associated with different SSBs.

[0245] Specifically, the SSB corresponding Preamble is first mapped to the DMRS of 1 PUO according to the numbering order of the PUSCH resource units, and then mapped according to the numbering order of the PUO; the PUSCH numbering interval L=2; the SSB of an RO is regarded as an SSB group, and 4 SSBs ar...

Embodiment approach 2

[0251] Embodiment 2: The DMRS of the PUO is associated with the Preamble in the order of the Preamble first and then the SSB, and multiple consecutive DMRSs are associated with the same SSB.

[0252] For example, the DMRS of the PUO is first mapped to the Preambles corresponding to the two SSBs according to the numbering sequence of the Preambles, and then mapped according to the numbering sequence of the SSBs, and the mapping interval of the SSBs is V=0.

[0253] For another example, the Preamble of the SSB is associated with the DMRS of the PUO in the order of the PUSCH resource unit first and then the PUO, and multiple consecutive DMRS are associated with the same SSB.

[0254] Specifically, the Preamble corresponding to the SSB is first mapped to the DMRS of one PUO according to the numbering order of the PUSCH resource units, and then mapped according to the numbering order of the PUOs; the PUSCH numbering interval L=1; the SSB of an RO is used as an SSB group, and 4 SSBs ...

Abstract

The invention provides a mapping method, terminal equipment and network side equipment, and the method comprises the steps: transmitting a random access message according to a target mapping relationbetween a physical uplink shared channel transmission PUSCH resource and a synchronization signal block SSB related resource; wherein the target mapping relationship is determined according to a preset mapping rule. According to the mapping method provided by the invention, blind detection on transmission positions on all possible SSB related resources and PUSCH resources can be avoided, so that the processing complexity is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mapping method, terminal equipment and network side equipment. Background technique [0002] Fifth generation (5 th Generation, 5G) mobile communication system, or New Radio (NR) system, needs to adapt to diverse scenarios and business requirements. The main scenarios of NR system include enhanced Mobile Broadband (eMBB) communication, large-scale IoT (massive Machine Type Communications, mMTC) communication and ultra-reliable and ultra-low latency communication (Ultra-Reliable and Low Latency Communications, URLLC). These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage. For services that occur periodically and have a fixed packet size, in order to reduce the overhead of downlink control signaling, network devices can use semi-static scheduling to continuously allocate certain resource...
