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) technology (or 5G). The 3GPP RAN #75 plenary meeting approved the NR (New Radio) technology WI (Work Item), initiating standardization work for NR. The 3GPP RAN #86 plenary meeting decided to begin work on the NR Rel-17 SI (Study Item) and WI (Work Item), and the 3GPP RAN #94e plenary meeting initiated the NR Rel-18 SI and WI projects. The 3GPP RAN #102 plenary meeting decided to begin work on the NR Rel-19 SI and WI.

[0003] NR Rel-19 includes support for Subband Non-Overlapping Full Duplex (SBFD). SBFD is also one of the technologies that 6G may support. 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 becomes a possible solution.

[0005] This application discloses a solution to the problem of random access configuration in supporting flexible duplex modes. It should be noted that the description in this application uses flexible duplex mode as only a typical application scenario or example; this application is also applicable to 6G networks or 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 scenarios supporting full-duplex on the same frequency), or for different application scenarios, such as eMBB, URLLC, non-terrestrial networks, inductively coupled networks, smart metasurfaces, and terahertz networks, achieving similar technical effects. Furthermore, using a unified solution for different scenarios (including but not limited to eMBB, URLLC, non-terrestrial networks, inductively coupled networks, smart metasurfaces, and terahertz networks) or different application parameters helps reduce hardware complexity and cost. Where there is no conflict, the terminal embodiments and features in the embodiments of this application can be applied to the base station of this application, and vice versa.

The MAC sublayer 302 provides multiplexing between logical and transport channels. It is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among terminals. Furthermore, the MAC sublayer 302 handles HARQ operations. In the control plane 300, the RRC (Radio Resource Control) sublayer 306 in L3 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the base station and the terminal. The radio protocol architecture of the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture for terminals and base stations in the user plane 350 is largely the same as the corresponding layers and sublayers in the control plane 300 for Physical Layer 351, PDCP sublayer 354 in L2355, RLC sublayer 353 in L2355, and MAC sublayer 352 in L2355. However, PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.The L2355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for mapping between QoS (Quality of Service) streams and Data Radio Bearers (DRBs) to support service diversity. Although not illustrated, the terminal may have several upper layers above the L2355, including a network layer (e.g., the IP (Internet Protocol) layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.).

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 PRACH is transmitted by the transmitter processor 455 via the transmitter 456 to the antenna 460 in the form of a radio frequency signal. The receiver 416 receives the radio frequency signal through its corresponding antenna 420.

[0625] Example 12

[0626] Example 12 illustrates a structural block diagram of a processing device in a terminal according to an embodiment of this application, as shown in the attached diagram. Figure 12 As shown. In the appendix Figure 12 In the terminal, the processing device 1200 includes a first receiver 1201 and a first transmitter 1202. The first receiver 1201 includes the components outlined in the appendix of this application.

Figure 4The transmitter / receiver 456 (including antenna 460), the transmitter processor 455, and the controller / processor 490 are included.

[0627] In embodiment 12, a first receiver 1201 receives a first information block and a second information block. The first information block indicates the symbol type of at least one symbol, and the second information block indicates a first RO resource set and multiple preamble set lists. Each of the multiple preamble set lists includes at least one preamble set. A first transmitter 1202 transmits a first PRACH in a target RO, which belongs to the first RO resource set. The preamble sequence carried by the first PRACH belongs to the first preamble set. The first preamble set is a preamble set included in one of the multiple preamble set lists. The first preamble set is associated with a first feature combination, which includes at least one feature. The multiple preamble set lists correspond to multiple symbol types. The preamble set list to which the first preamble set belongs is the first preamble set list, which is a preamble set list among the multiple preamble set lists that corresponds to the symbol type of at least one symbol included in the target RO in the time domain.

[0628] As one embodiment, the first preamble set includes a plurality of consecutive preambles associated with a synchronous broadcast signal, and the second information block indicates the index value of the starting preamble of the plurality of consecutive preambles included in the first preamble set.

The second preamble set is one of the preamble sets in the first preamble set list that are not associated with any feature or one of the preamble sets outside the first preamble set list.

[0631] As an example, the symbol type of at least one symbol included in the target RO in the time domain depends on the relationship between the first RSRP and the first threshold and the relationship between the value of the first counter and the first value, wherein the value of the first counter is equal to the count value of PRACH transmission using the RO located on a full-duplex symbol; the first RSRP is an RSRP for downlink path loss reference; and the second information block indicates the first threshold and the first value.

[0633] As an example, when the target RO includes at least one full-duplex symbol in the time domain that is indicated as downlink by TDD uplink / downlink configuration, the first feature combination includes only features other than full-duplex features; when the target RO includes a non-full-duplex symbol in the time domain or is indicated as a flexible full-duplex symbol by TDD uplink / downlink configuration, the first feature combination may include full-duplex features.

[0634] Example 13

[0635] Example 13 illustrates a structural block diagram of a processing apparatus for a base station according to an embodiment of this application, as shown in the attached diagram. Figure 13 As shown. In the appendix Figure 13 In the base station, the processing device 1300 includes a second transmitter 1301 and a second receiver 1302. The second transmitter 1301 includes the components specified in the appendix of this application. Figure 4 The transmitter / receiver 416 (including antenna 420), the transmitter processor 415, and the controller / processor 440 are included; the second receiver 1302 includes the appendix to this application. Figure 4 The transmitter / receiver 416 (including antenna 420), receiver processor 412, and controller / processor 440 are included.

[0636] In embodiment 13, a second transmitter 1301 transmits a first information block and a second information block. The first information block indicates the symbol type of at least one symbol, and the second information block indicates a first RO resource set and multiple preamble set lists. Each of the multiple preamble set lists includes at least one preamble set. A second receiver 1302 receives a first PRACH in a target RO, which belongs to the first RO resource set. The preamble sequence carried by the first PRACH belongs to a first preamble set, which is a preamble set included in one of the multiple preamble set lists. The first preamble set is associated with a first feature combination, which includes at least one feature. The multiple preamble set lists correspond to multiple symbol types, and the preamble set list to which the first preamble set belongs is a first preamble set list, which is a preamble set list among the multiple preamble set lists that corresponds to the symbol type of at least one symbol included in the target RO in the time domain.

[0637] As one embodiment, the first preamble set includes a plurality of consecutive preambles associated with a synchronous broadcast signal, and the second information block indicates the index value of the starting preamble of the plurality of consecutive preambles included in the first preamble set.

[0638] As one embodiment, the first feature combination includes a full-duplex feature, the second information block indicates a target threshold for the first feature combination, and the terminal selects to initiate random access on a full-duplex symbol based on a measured RSRP value exceeding the target threshold.

[0639] As an example, when the first preamble set list does not contain the preamble set associated with the first feature combination, the preamble sequence carried by the first PRACH belongs to the second preamble set. The second preamble set is one of the preamble sets in the first preamble set list that are not associated with any feature or one of the preamble sets outside the first preamble set list.

[0640] As an example, the symbol type of at least one symbol included in the target RO in the time domain depends on the relationship between the first RSRP and the first threshold and the relationship between the value of the first counter and the first value, wherein the value of the first counter is equal to the count value of PRACH transmission using the RO located on a full-duplex symbol; the first RSRP is an RSRP for downlink path loss reference; and the second information block indicates the first threshold and the first value.

[0641] As an example, the ROs in the first RO resource set located on full-duplex symbols indicated as downlink by TDD uplink / downlink configuration and the ROs in the first RO resource set located on non-full-duplex symbols or flexible full-duplex symbols indicated as uplink / downlink configuration by TDD uplink / downlink configuration are each mapped to a synchronization broadcast signal.

[0642] As an example, when the target RO includes at least one full-duplex symbol in the time domain that is indicated as downlink by TDD uplink / downlink configuration, the first feature combination includes only features other than full-duplex features; when the target RO includes a non-full-duplex symbol in the time domain or is indicated as a flexible full-duplex symbol by TDD uplink / downlink configuration, the first feature combination may include full-duplex features.
