Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission schemes and apparatus with flexible transmission direction configurations in wireless communication. Background Technology

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the system. To meet the diverse performance needs of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to conduct research on New Radio (NR) (or 5G). The 3GPP RAN #75 plenary meeting approved the NR Work Item (WI), initiating standardization work for NR. The 3GPP RAN #86 plenary meeting decided to begin work on the NR Rel-17 Study Item (SI) and Work Item (WI), and it is expected that the NR Rel-18 SI and WI will be approved at the 3GPP RAN #94e plenary meeting.

[0003] In new air interface technologies, enhanced mobile broadband (eMBB), ultra-reliable and low-latency communications (URLLC), and massive machine-type communications (mMTC) are three main application scenarios. Summary of the Invention

[0004] In existing NR systems, spectrum resources are statically divided into FDD and TDD spectrum. For TDD spectrum, both base stations and user equipment operate in half-duplex mode. This half-duplex mode avoids self-interference and mitigates cross-link interference, but it also leads to decreased resource utilization and increased latency. To address these issues, supporting flexible duplex modes on either TDD or FDD spectrum is a possible solution. Power control is an effective means of reducing self-interference and cross-link interference.

[0005] To address the issue of uplink power control supporting flexible duplex modes, this application discloses a solution. It should be noted that the flexible duplex mode described in this application is merely a typical application scenario or example; this application is also applicable to other scenarios facing similar problems (e.g., scenarios where link direction changes, or other scenarios supporting multi-level configuration of transmission directions, or scenarios with more capable base stations or user equipment, such as supporting full-duplex on the same frequency), or for different application scenarios, such as eMBB and URLLC, achieving similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to eMBB and URLLC scenarios) helps reduce hardware complexity and cost.

Figure 3The radio protocol architecture for the control plane 300 between the first node device (UE or gNB) and the second node device (gNB or UE) is illustrated using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second node devices via PHY301. L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node device.

These are then transmitted by the transmit processor 415 via the transmitter 416 to the antenna 420 as radio frequency (RF) signals. At the receiver, each receiver 456 receives the RF signal through its corresponding antenna 460. Each receiver 456 recovers the baseband information modulated onto the RF carrier and provides the baseband information to the receive processor 452.

The first signal and the physical layer signal carrying the third information block are mapped by transmitter processor 455 to antenna 460 and transmitted as radio frequency signals. Receiver 416 receives the radio frequency signals through its corresponding antenna 420. Each receiver 416 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to receiver processor 412. Receiver processor 412 implements various signal reception processing functions for the L1 layer (i.e., physical layer), including receiving and processing the first signal and the physical layer signal carrying the third information block, and subsequently providing data and / or control signals to controller / processor 440. The L2 layer functions implemented by controller / processor 440 include interpreting higher-layer information such as the first signal (if the first signal carries higher-layer information) and the third information block.

[0614] Example 8 illustrates a schematic diagram showing the relationship between the resource block allocation type of a first signal and a first threshold according to an embodiment of this application, as shown in the attached diagram. Figure 8 As shown. In the appendix Figure 8In this context, ceil(x) represents the smallest integer greater than or equal to x. The resource block allocation type of the first signal depends on the frequency domain bandwidth of the first signal being less than or equal to ceil(first threshold / 2). The first threshold depends on at least one of the bandwidth of the first sub-band, the index value of the starting resource block of the first sub-band, and the index value of the ending resource block of the first sub-band.

[0697] As an example, the sum of the number of unallocated resource blocks for the first signal and the number of allocated resource blocks for the first signal is greater than a second threshold, the second threshold depending on the subcarrier spacing.

[0698] As a supplementary embodiment of this example, the second threshold is predefined under different subcarrier intervals.

[0743] In embodiment 13, the second transceiver 1301 transmits a first information block indicating configuration information of a first sub-frequency band. The first sub-frequency band is a full-duplex sub-frequency band, and the configuration information of the first sub-frequency band includes at least one of the resource blocks included in the first sub-frequency band or time-domain symbols for the first sub-frequency band. The second transceiver 1301 receives a first signal, which is allocated at least one resource block in the frequency domain. Any resource block allocated to the first signal in the frequency domain belongs to the first sub-frequency band. The transmit power of the first signal is equal to the smaller of a first transmit power and a maximum output power. The first transmit power depends on path loss, and the range of the maximum output power depends on the value of a first parameter. The value of the first parameter depends on the resource block allocation type of the first signal, and the resource block allocation type of the first signal depends on the frequency domain location of the first sub-frequency band.

[0744] As one embodiment, the second transceiver 1301 transmits a second information block; wherein the second information block indicates a target BWP, and at least one of the positions of the first sub-band in the target BWP or the positions of the first sub-band in the maximum channel bandwidth is used to determine the target frequency domain range; the resource block allocation type of the first signal depends on the starting resource block to which the first signal is allocated belonging to the target frequency domain range.

[0745] As an example, when the first sub-frequency band is at the upper end of the target BWP, the target frequency domain range depends on the index value of the starting resource block of the first sub-frequency band and the number of resource blocks of the maximum channel bandwidth; when the first sub-frequency band is at the lower end of the target BWP, the target frequency domain range depends on the index value of the ending resource block of the first sub-frequency band; otherwise, the target frequency domain range depends on the index value of the starting resource block of the first sub-frequency band and the index value of the ending resource block of the first sub-frequency band.

[0746] As an example, the resource block allocation type of the first signal depends on the up-rounded value of the frequency domain bandwidth of the first signal being no greater than half of a first threshold, wherein the first threshold depends on at least one of the bandwidth of the first sub-band, the index value of the starting resource block of the first sub-band, and the index value of the ending resource block of the first sub-band.

[0747] As an example, the first signal employs CP-OFDM, and the frequency domain bandwidth of the first signal is equal to the sum of the number of unallocated resource blocks for the first signal and the number of allocated resource blocks for the first signal. The ratio between the number of unallocated resource blocks for the first signal and the frequency domain bandwidth of the first signal is not greater than a first ratio value, which is predefined or configured. The number of unallocated resource blocks for the first signal is the total number of unallocated resource blocks among the allocated resource blocks of the first signal. The value of the first parameter depends on the number of unallocated resource blocks for the first signal and the number of allocated resource blocks for the first signal.

[0748] As one embodiment, the second transceiver 1301 receives a third information block; wherein the third information block indicates that the sender of the third information block supports uplink transmission within the first sub-band in symbols configured with the first sub-band.

[0749] As an example, there is an overlap between at least one time-domain symbol assigned to the first signal and at least one time-domain symbol for the first sub-band.
