In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application. The embodiments of this application include at least part of the following contents.

As NR systems evolve, research on NR systems can include new frequency bands such as 52.6GHz–71GHz or 71GHz–114.25GHz. The new frequency band may include licensed spectrum or unlicensed spectrum. In other words, the new frequency band includes dedicated spectrum and shared spectrum. The subcarrier spacing considered in the new frequency band can be larger than the subcarrier spacing supported by the existing NR system, for example, the subcarrier spacing can be 480kHz or 960kHz.

In order to facilitate a better understanding of the embodiments of the present application, the network energy saving related to the present application will be described.

Network energy saving is of great significance to environmental sustainability, reducing environmental impact (reducing greenhouse gas emissions), and saving operating costs. As 5G becomes more popular across industries and geographical regions, very high data transmission rates will need to be supported to handle more advanced services and applications (such as Extended Reality (XR)), and network deployments will become denser and more used. Multiple antennas, greater bandwidth and more frequency bands. Considering the impact of 5G on the environment, controlled, new solutions need to be developed to enhance network energy conservation.

Energy consumption has become a key part of operators' operational expenses (OPEX). According to the GSMA report, the energy cost of mobile networks accounts for approximately 23% of total operating costs. Most energy consumption comes from wireless access networks, more specifically from Active Antenna Units (AAUs), with data centers and fiber optic transmission accounting for a smaller share. The power consumption of a wireless access can be divided into two parts: the dynamic part only includes the power consumption when data is being sent or received; the static part includes the power required to maintain the necessary operation of the wireless access device at all times. Consumption, including power consumption when not sending or receiving data.

Therefore, based on the above purpose, it is necessary to research and develop network energy consumption models, key performance indicators (KPI), evaluation methods, etc. on the network device side to determine and study network energy-saving technologies in target deployment scenarios. Among them, the defined power consumption model on the terminal device side can be used as a reference. This research should focus on how to achieve more efficient dynamic operation and/or semi-static operation, and consider one or more network energy-saving technologies applied in the time domain, frequency domain, air domain and power domain, combined with potential terminal equipment feedback support , potential terminal device auxiliary information, and technologies such as information exchange or coordination between network interfaces to achieve more fine-grained data transmission and/or reception adaptation.

It is worth noting that this study not only evaluates potential network energy-saving gains, but also needs to observe KPIs such as spectral efficiency, capabilities, user perceived throughput (UPT), latency, and terminal equipment power consumption (UE power consumption). ), complexity, handover performance, call drop rate, initial access performance, service-level agreement (Service-Level Agreement, SLA) security-related KPIs, etc., to evaluate and balance the impact on network and user performance Influence. The research should avoid having a large impact on the above KPIs.

In order to facilitate a better understanding of the embodiments of the present application, the PDSCH resource mapping in the NR system related to the present application will be described.

In the NR system, when receiving the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) scheduled by the System Information Radio Network Temporary Identity (SI-RNTI) and the downlink control information corresponding to the SI-RNTI ( The system information indication included in Downlink Control Information (DCI) is 0 (or when receiving the PDSCH scheduled by SI-RNTI including SIB1 information), the terminal equipment should assume that the resource element (Resource Element, RE) included in the received PDSCH ) is used for Synchronization Signal Block (SSB) transmission.

When the PDSCH scheduled by SI-RNTI is received and the System Information (SI) indicator included in the DCI corresponding to SI-RNTI is 1 (or in other words, when the PDSCH scheduled by SI-RNTI is received, the system information other than SIB1 is included) , or receive Random Access Radio Network Temporary Identity (RA-RNTI), Message B Radio Network Temporary Identity (MsgB-RNTI), Paging Radio Network Temporary Identity (Paging When the PDSCH is scheduled by Radio Network Temporary Identity (P-RNTI) or Temporary Cell Radio Network Temporary Identity (TC-RNTI), the terminal equipment should be based on the SSB indication information such as the position in the SSB burst (ssb- PositionsInBurst) to assume the transmitted SSB. If the physical resource block (PRB) in the scheduled PDSCH overlaps with the PRB used to transmit the SSB, then the terminal device should assume this overlap on the symbols transmitted by the SSB. The resources corresponding to the PRB (or resources used to transmit SSB) are not used for PDSCH transmission.

It should be noted that SSB can also be called synchronization signal/physical broadcast channel block (SS/PBCH block).

The terminal device should expect that the SSB configuration provided by ssb-PositionsInBurst in the serving cell common configuration (ServingCellConfigCommon) is the same as the SSB configuration provided by ssb-PositionsInBurst in SIB1.

When receiving the Cyclical Redundancy Check (CRC) scrambling code, it is Cell Radio Network Temporary Identity (C-RNTI), Modulation and Coding Scheme Cell Radio Network Temporary Identity (Modulation and Coding Scheme Cell). Radio Network Temporary Identity, MCS-C-RNTI) or configured to schedule the Radio Network Temporary Identity (Configured Scheduling Radio Network Temporary Identity, CS-RNTI) physical downlink control channel (Physical Downlink Control Channel, PDCCH) scheduled PDSCH, or receive When Semi-Persistent Scheduling Physical Downlink Shared Channel (SPS PDSCH) is scheduled, the corresponding RE in the configured or dynamically indicated resource set is not used for PDSCH transmission. Further, the terminal equipment should assume the transmitted SSB based on the SSB indication information such as ssb-PositionsInBurst. If the PRB in the scheduled PDSCH overlaps with the PRB used to transmit the SSB, then the terminal equipment should assume that the SSB is transmitted on the symbol. The resources corresponding to the overlapping PRB (or resources used to transmit SSB) are not used for PDSCH transmission.

The terminal equipment does not expect to handle the situation where the physical downlink shared channel demodulation reference signal (Physical Downlink Shared Channel Demodulation Reference Signal, PDSCH DM-RS) RE partially or completely overlaps with the RE not used for PDSCH transmission, or the terminal equipment expects the PDSCH DM- RS REs are all transmitted REs (or effective REs). The REs not used for PDSCH transmission include at least one of the following: corresponding REs in configured or dynamically indicated resource sets, and PRBs that transmit SSB on symbols for SSB transmission.

On the unlicensed spectrum, the transmitted SSB determined according to the SSB indication information, such as ssb-PositionsInBurst, includes: all candidate SSBs corresponding to the transmitted SSB index determined according to the SSB indication information, such as ssb-PositionsInBurst.

The terminal equipment may be configured with a resource set, and the corresponding REs in the resource set are not used for PDSCH transmission. In this resource set, the terminal device can be configured with up to 4 rate matching patterns on each bandwidth part (Band Width Part, BWP), and can be configured with up to 4 rate matching patterns on each serving cell.

Among them, a rate matching pattern can include:

(1) Within the BWP, a set of reserved resources configured by BWP or by serving cell. Among them, when configured by BWP, the reserved resources configured on each BWP are determined based on the subcarrier spacing of the BWP; when configured by serving cells, the reserved resources configured on each serving cell are determined based on independent Determined by the configured subcarrier spacing. The set of reserved resources is indicated in the frequency domain by a bitmap corresponding to a resource block (RB) granularity, and in the time domain by a bitmap corresponding to a symbol granularity. Indicated, the time domain range indicated in the time domain is 1 or 2 time slots. When the bit value corresponding to the RB is 1 and the bit value corresponding to the symbol is 1, it indicates that the corresponding RB-symbol resource is not used for PDSCH transmission. This group of reserved resources appears periodically in the time domain. The terminal device can be configured with a bitmap corresponding to a period. Each bit in the bitmap corresponds to a group of reserved resources. When a certain bit has a value of 1, it indicates The set of reserved resources exists at the time domain position corresponding to the bit in this period. The length of the period can correspond to {1, 2, 4, 5, 8, 10, 20, 40} groups of reserved resources, but the maximum value is 40ms. Assume that the length of the period is P ms, then the first symbol in every 40 ms or every P ms is the first symbol in the wireless frame n _f that satisfies n _f mod 4=0. When the terminal device is not configured with a bitmap corresponding to a period, for a set of reserved resources corresponding to 2 time slots in the time domain, the first time slot and the second time slot respectively correspond to a wireless frame. Even-numbered time slots and odd-numbered time slots; for a set of reserved resources corresponding to 1 time slot in the time domain, the time slot corresponds to each time slot in a wireless frame. The set of reserved resources may be included in a resource set corresponding to rate matching pattern group 1 and/or rate matching pattern group 2.

(2) Within the BWP, the resources used to transmit PDCCH can be determined based on the frequency domain resource configuration of the Control Resource Set (CORESET), the number of symbols occupied by CORESET, and the time domain resource configuration of the search space. The resources of the PDCCH that are not used for PDSCH transmission may be included in the resource set corresponding to the rate matching pattern group 1 and/or the rate matching pattern group 2.

Optionally, the resource set is a resource set corresponding to RB-symbols, or in other words, the unit of the resource set in the time domain is a symbol, and the unit in the frequency domain is an RB.

The terminal device may be configured with rate matching pattern group 1 or rate matching pattern group 2. The rate matching pattern group 1 or the rate matching pattern group 2 includes one or more rate matching patterns. When the received PDSCH is scheduled using DCI format 1_0, or is an SPS PDSCH activated using DCI format 1_0, or is scheduled for DCI format 1_1 (or DCI format 1_2) and DCI format 1_1 (or DCI format 1_2) does not include rate matching When indicating the information, the terminal equipment shall assume that rate matching pattern group 1 or rate matching pattern group 2 is not used for PDSCH transmission.

If the DCI format 1_1 (or DCI format 1_2) includes rate matching indication information, the rate matching indication information is used to dynamically indicate whether the configured rate matching pattern group 1 or rate matching pattern group 2 is used for PDSCH transmission. Wherein, the PDSCH includes a PDSCH dynamically scheduled by DCI format 1_1 (or DCI format 1_2), and/or the PDSCH includes a SPS PDSCH activated by DCI format 1_1 (or DCI format 1_2). For example, the rate matching indication information includes 2 bits, where the first bit corresponds to rate matching pattern group 1 and the second bit corresponds to rate matching pattern group 2. If the bit in the rate matching indication information is 1, it means that the resources in the rate matching pattern group corresponding to the bit are not used for PDSCH transmission. For resources in the resource set that do not belong to rate matching pattern group 1 and do not belong to rate matching pattern group 2, when the received PDSCH is scheduled or activated using DCI format 1_1 (or DCI format 1_2), the terminal equipment should assume that the resource is not used transmitted on PDSCH.

Optionally, if DCI format 1_1 is scheduled or activated, rate matching pattern group 1 includes rate matching pattern group 1-1, and rate matching pattern group 2 includes rate matching pattern group 2-1. The rate matching indication information in DCI format 1_1 indicates whether the rate matching pattern group 1-1 or the rate matching pattern group 2-1 is used for PDSCH transmission.

Optionally, if DCI format 1_2 is scheduled or activated, rate matching pattern group 1 includes rate matching pattern group 1-2, and rate matching pattern group 2 includes rate matching pattern group 2-2. The rate matching indication information in DCI format 1_2 indicates whether the rate matching pattern group 1-2 or the rate matching pattern group 2-2 is used for PDSCH transmission.

Optionally, the rate matching pattern group 1-1, the rate matching pattern group 2-1, the rate matching pattern group 1-2, and the rate matching pattern group 2-2 correspond to different high-level configuration parameters.

In order to facilitate a better understanding of the embodiments of the present application, network energy-saving technologies related to the present application will be described.

One method is to increase the transmission period of SSB and SIB1 when the network is idle. However, this method will increase the initial access delay of the terminal device. Therefore, for an existing terminal device, it may not be able to correctly identify the cell during a long SSB transmission period, and thus be unable to access the network. .

For some scenarios, especially when the terminal device is already able to receive SSB and SIB1 through the first carrier, the common signal transmitted on the second carrier can be simplified, and/or the common signal transmitted on the second carrier can be The signal (such as System Information (SI)) sent on the first carrier is used to assist reception. As shown in Figure 2 below, the common signal transmitted on the second carrier (that is, other carriers) only occupies 2 symbols. Compared with the 4 symbols occupied by the existing SSB, the number of occupied symbols is smaller. At the same time, the common signal can also Reduce the impact on the synchronization accuracy performance and access delay of terminal equipment.

In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application will be described.

In the current network energy-saving technical solution, when the terminal device can already receive SSB and SIB1 through the first carrier, the common signals transmitted on the second carrier can be simplified, and/or the common signals transmitted on the second carrier can be Reception is assisted by signals transmitted on the first carrier. That is to say, for the terminal equipment, the common signal on the second carrier may be transmitted on the first carrier. In this case, when the terminal device is scheduled to receive a PDSCH, how to determine the resource mapping information of the PDSCH, or how to perform rate matching of the PDSCH, is a problem to be solved.

Based on the above problems, this application proposes a solution for determining the resource mapping information of the shared channel. The resources that may not be used for shared channel transmission on the first cell include the resources used for transmitting information of the second cell on the first cell. Therefore, the terminal device can accurately determine the resource mapping information of the first shared channel received on the first cell, thereby improving the reliability of data transmission.

Or a certain cell or part of two or more cells, such as the first cell, and for the carrier to which the terminal device is transferred, such as the second cell, the network device can turn off the second cell or only transmit on the second cell. Basic public signals are used to maintain the initial access, paging and other functions of terminal equipment, thereby achieving the purpose of saving network energy consumption.

In addition, the network device may also transmit public parameters and/or public signals in the second cell through the first cell that need to be transmitted in order to maintain necessary operations of the wireless access device. Since the first cell may include new terminal equipment with enhanced capabilities or old terminal equipment without enhanced capabilities, the old terminal equipment cannot identify the public parameters and/or corresponding to the second cell sent by the network device. Therefore, in this case, the network device needs to instruct the terminal device to perform rate matching on the common parameters transmitted in the first cell corresponding to the second cell and/or the resources occupied by the public signal.
