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 may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

The main application scenario of 5G is: enhanced mobile Ultra-wideband (Enhance Mobile Broadband, emmbb), low latency high reliability communications (Ultra-Reliable and Low Latency Communication, URLLC), large scale machine type communications (massive machine type of communication, mctc).

embbs still target users to obtain multimedia content, services, and data, and their demand is growing very rapidly. On the other hand, since the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., the capability and demand of the eMBB are also relatively different, so that detailed analysis must be performed in connection with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical characteristics of mctc include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

NR is deployed at high frequencies, and in order to improve coverage, in 5G, the need for coverage (coverage with space and space with time) is met by introducing a beam scanning mechanism, as shown in fig. 2.

After the introduction of beam sweep, a synchronization signal needs to be transmitted in each beam direction, and the synchronization signal of 5G is given in the form of a synchronization signal block (SS/PBCH block, SSB), including a primary synchronization signal (Primary Synchronization Signal, PSS)/a secondary synchronization signal (Secondary Synchronization Signal, SSs)/a physical broadcast channel (Physical Broadcast Channel, PBCH).

The synchronization signal of 5G occurs periodically in the time domain in the form of a synchronization signal burst (Synchronization Signal burst set).

The number of beams (beams) actually transmitted by each cell is determined by the network side configuration, but the frequency point where the cell is located determines the maximum number of beams (beams) that can be configured.

In 5G, the maximum channel bandwidth may be 400MHz (e.g., wideband carrier), which is large compared to the maximum 20M bandwidth of LTE. If the terminal device remains operating on the broadband carrier, the power consumption of the terminal device is significant. Thus, the Radio Frequency (RF) bandwidth of the terminal device may be adjusted according to the actual throughput of the terminal device. And introduces a bandwidth Part (BWP) to optimize the power consumption of the terminal device. For example, the rate of the terminal device is low, a smaller bandwidth may be configured for the terminal device (as shown in (a) of fig. 3), and if the rate requirement of the terminal device is high, a larger bandwidth may be configured for the terminal device (as shown in (b) of fig. 3). If the terminal device supports a high rate or operates in a carrier aggregation (Carrier Aggregation, CA) mode, the terminal device may be configured with a plurality of BWPs (as shown in (c) of fig. 3). Another purpose of BWP is to trigger coexistence of multiple basic parameter sets (numerology) in one cell.

In some embodiments, up to 4 Uplink (UL) BWP and up to 4 Downlink (DL) BWP may be configured to one terminal device through radio resource control (Radio Resource Control, RRC) dedicated signaling, but only one DL BWP and UL BWP may be activated at the same time. In RRC dedicated signaling, the first activated BWP of the configured BWP may be indicated. Meanwhile, in the process that the terminal equipment is in a connection state, different BWPs can be switched through downlink control information (Downlink Control Information, DCI). When the carrier in the inactive state enters the active state, the first active BWP is the first active BWP configured in RRC.

In some embodiments, the configuration parameters for each BWP comprise:

subcarrier spacing (subsearrierspace);

cyclic prefix (cyclic prefix);

a first physical resource block (physical resource block, PRB) of the BWP and a consecutive number of PRBs;

location and bandwidth (locationAndBandwidth);

BWP identification (BWP-Id);

BWP Common configuration parameters (BWP-Common) and Dedicated configuration parameters (BWP-Dedicated).

In some embodiments, the UE performs on the active BWP only during the listening radio link monitoring (radio link monitoring, RLM), the inactive BWP does not need to operate, nor does it need to reset the RLM-related timer and counter when switching between different BWP. For radio resource management (Radio Resource Management, RRM) measurements, the RRM measurements are not affected, regardless of whether the UE is transceiving data on that activated BWP. For measurement of channel quality indication (Channel Quantity Indicator, CQI), the UE also only needs to perform on the activated BWP.

When a carrier is deactivated and then activated by a medium access control element (Media Access Control Control Element, MAC CE), the initial first activated BWP is the BWP corresponding to the first activated BWP identification (BWP id) in RRC signaling.

BWP id takes values 0 to 4 in RRC signaling, and 0 defaults to initial BWP.

The BWP indication (indicator) is 2 bits (bits) in the DCI. If the number of BWP configured is 3 or less, BWP indicator=1, 2,3 corresponds to BWP id=1, 2,3, respectively. If the number of BWP is 4, BWP indicator=0, 1,2,3 correspond to BWP configured in order index, respectively. And the network side uses consecutive BWP ids when configuring BWP.

Carrier aggregation (Carrier Aggregation, CA), i.e. by jointly scheduling and using resources on multiple component carriers (Component Carrier, CC), enables the NR system to support a larger bandwidth, enabling higher system peak rates. Spectrum continuity according to the aggregated carriers can be divided into continuous carrier aggregation and discontinuous carrier aggregation; the band in which the aggregated carriers are located is classified into an in-band (Intra-band) carrier aggregation and an out-of-band (inter-band) carrier aggregation according to whether the bands are identical.

The primary carrier (Primary Cell Component, PCC) has and only one, and the PCC provides RRC signaling connections, non-Access Stratum (NAS) functions, security, etc. The physical uplink control channel (Physical Uplink Control Channel, PUCCH) is present on and only on the PCC. The secondary carrier (Secondary Cell Component, SCC) provides only additional radio resources. The PCC and SCC are commonly referred to as serving cells. The maximum bandwidth of the aggregated carriers supports 5 carriers, namely the maximum bandwidth after aggregation is 100MHz, and the aggregated carriers belong to the same base station. All aggregated carriers use the same cell radio network temporary identity (Cell Radio Network Temporary Identity, C-RNTI), and the base station implements the guarantee that the C-RNTI does not collide in the cell where each carrier is located. Since both asymmetric carrier aggregation and symmetric carrier aggregation are supported, the carriers requiring aggregation must have downlink and may not have uplink. And there must be a physical downlink control channel (Physical Downlink Control Channel, PDCCH) and PUCCH of the own cell for the primary carrier cell, and only the primary carrier cell has PUCCH, and other secondary carrier cells may have PDCCH.

The SCell is configured through RRC dedicated signaling, and the initially configured state is a deactivated state, and data transmission and reception cannot be performed in the deactivated state. And then the data can be received and transmitted only by activating the SCell through the MAC CE. For example, as shown in fig. 4, an SCell is activated (Activation) or deactivated (Deactivation) by 1 8-bit byte (Oct) of the MAC CE. As another example, as shown in fig. 5, an SCell is activated (Activation) or deactivated (Deactivation) by 4 8-bit bytes (Oct) of the MAC CE. Specifically, for example, a bit set to 0 indicates that the corresponding Scell is deactivated, and a bit set to 1 indicates that the corresponding Scell is activated; alternatively, a bit set to 1 indicates that the corresponding Scell is deactivated and a bit set to 0 indicates that the corresponding Scell is activated.

In some embodiments, the state of the Scell may be in RRC signaling, and when the Scell adds configuration, the state of the Scell is configured to be an active state through RRC signaling, otherwise the state is deactivated by default.

In order to better understand the embodiments of the present application, the technical problems to be solved by the present application are described.

At present, the MAC CE mode requires a time delay from activation of a Scell to the actual transmission of data. Considering that the length of the large SSB period affects the time for which the Scell is actually activated, a TRS is introduced to assist the terminal device in quickly activating the Scell. The transmission of the TRS occupies two consecutive slots (slots), and may collide with other transmissions, for example, the TRS transmission and the transmission on the UL slot, so that the TRS transmission is unsuccessful, and how to identify the collision and process the collision is a problem to be solved.

Based on the above-mentioned problems, the present application proposes a scheme for identifying and processing transmission collision, which can identify and process collision between transmission of a first reference signal and uplink transmission, and in the case that the first reference signal is TRS, the terminal device can quickly activate SCell based on the first reference signal.

The technical scheme of the present application is described in detail below through specific embodiments.

Fig. 6 is a schematic interaction flow diagram of a method 200 of wireless communication according to an embodiment of the present application, as shown in fig. 6, the method 200 of wireless communication may include at least some of the following:

s210, the network equipment sends first information and second information; the first information is used for determining transmission direction information, the second information is used for determining time domain position information of a first reference signal, the first reference signal is used for activating a carrier, the time domain position information of the first reference signal comprises at least one reference signal cluster, and one reference signal cluster corresponds to two continuous time slots;

s220, the terminal equipment receives first information, wherein the first information is used for determining transmission direction information;

s230, the terminal equipment receives second information, wherein the second information is used for determining time domain position information of a first reference signal, the first reference signal is used for activating a carrier, the time domain position information of the first reference signal comprises at least one reference signal cluster, and one reference signal cluster corresponds to two continuous time slots;

s240, the terminal equipment determines a first receiving scheme for receiving the first reference signal according to the first information and the second information.

In some embodiments, the first reference signal is a TRS or a reference signal similar in function to a TRS. Of course, the first reference signal may be another reference signal, which is not limited in this application.

It should be noted that, the transmission of the first reference signal may collide with the uplink transmission sent by the uplink time unit, and/or the transmission of the first reference signal may collide with the uplink transmission sent by the flexible time unit, which may further result in failure of the transmission of the first reference signal. For example, as shown in fig. 7, the terminal device is configured to receive TRSs on a first TRS cluster including one DL slot and one UL slot and a second TRS cluster including two DL slots. As shown in fig. 7, in the first TRS cluster, there is a collision between the TRS transmission on the UL slot and the uplink transmission on the uplink slot. In addition, a channel state information reference signal (Channel State Information Reference Signal, CSI-RS) resource 1, a CSI-RS resource 2, a CSI-RS resource 3, and a CSI-RS resource 4 are present in the first TRS cluster, and a CSI-RS resource 1, a CSI-RS resource 2, a CSI-RS resource 3, and a CSI-RS resource 4 are also present in the second TRS cluster.

In this embodiment of the present application, the first information is used to determine transmission direction information, the second information is used to determine time domain location information of a first reference signal, the first reference signal is used to activate a carrier, the time domain location information of the first reference signal includes at least one reference signal cluster, and one reference signal cluster corresponds to two consecutive slots. Thus, the terminal device may determine a first reception scheme for receiving the first reference signal based on the first information and the second information. Therefore, the receiving mode of the first reference signal can be optimized, and the transmission of the first reference signal is prevented from colliding with the transmission of other signals.

In some embodiments, the time units described in embodiments of the present application include, but are not limited to, one of the following: time slot, symbol.

In the flexible time slot and the flexible symbol, uplink transmission and downlink transmission can be performed.

In some embodiments, the first information is carried by RRC signaling or DCI. For example, the first information may be at least one of an element, a field in RRC signaling or DCI. Of course, the first information may also be carried by other signaling, which is not limited in this application.

In some embodiments, the second information is carried by RRC signaling or DCI. For example, the second information may be at least one of an element, a field in RRC signaling or DCI. Of course, the second information may also be carried by other signaling, which is not limited in this application.

In some embodiments, the first information and the second information may be carried by the same signaling, or may be carried by different signaling, which is not limited in this application.

In some embodiments, the terminal device may also obtain the first information and the second information through other devices besides the network device, which is not limited in this application.

In some embodiments, the interval between any two adjacent reference signal clusters in the at least one reference signal cluster satisfies a protocol convention or a network configuration, e.g., is 2 slots apart.

In some embodiments, a reference signal cluster of the at least one reference signal cluster may be a TRS cluster (TRS burst).

In some embodiments, the first reception scheme includes: the terminal device does not expect any one of the time units for transmitting the first reference signal to be an uplink time unit.

Specifically, for example, the terminal device does not expect any one of the slots for transmitting the first reference signal to be an UL slot, or the terminal device does not expect any one of the symbols for transmitting the first reference signal to be an UL symbol. Typically, the network side needs to ensure that the time domain position of the triggered first reference signal transmission is not UL slot or UL symbol. Even if the network side cannot guarantee that the terminal device can adopt a mode which is not constrained by the protocol, for example, the terminal device does not receive the first reference signal on an uplink time slot or an uplink symbol.

In some embodiments, the first reception scheme includes: the terminal device does not expect any one of the time units for transmitting the first reference signal to be a flexible time unit.

Specifically, for example, the terminal device does not expect any slot for transmitting the first reference signal to be a flexible (flexible) slot, or the terminal device does not expect any symbol for transmitting the first reference signal to be a flexible (flexible) symbol. Typically, the network side needs to ensure that the triggered time domain position of the first reference signal transmission is not a flexible slot or a flexible symbol. Even if the network side cannot guarantee that the terminal device can adopt a mode which is not constrained by the protocol, for example, the terminal device does not receive the first reference signal on a flexible time slot or a flexible symbol.

In some embodiments, the first reception scheme includes: the terminal device does not expect that both consecutive slots in a reference signal cluster are uplink slots. That is, at least one time slot in one reference signal cluster is a downlink time slot. Even if the network side cannot guarantee that the terminal device can adopt a mode which is not constrained by the protocol, for example, the terminal device does not receive the first reference signal on the uplink time slot.

In some embodiments, the first reception scheme includes: the terminal device does not expect that both consecutive slots in a reference signal cluster are flexible slots. That is, at least one time slot in one reference signal cluster is a downlink time slot. Even if the network side cannot guarantee that the terminal device can adopt a mode which is not constrained by the protocol, for example, the terminal device does not receive the first reference signal on a flexible time slot.

In some embodiments, the first reception scheme includes: the terminal device does not expect two consecutive slots in a reference signal cluster, one slot being a flexible slot and the other slot being an uplink slot. That is, at least one time slot in one reference signal cluster is a downlink time slot. Even if the network side cannot guarantee that the terminal device can adopt a mode which is not constrained by the protocol, for example, the terminal device does not receive the first reference signal on an uplink time slot or a flexible time slot.

In some embodiments, the first reception scheme includes: the terminal device does not expect that the symbols in both consecutive slots in one reference signal cluster that are used for transmitting the first reference signal are uplink symbols or flexible symbols.

In some embodiments, the first reception scheme includes: the terminal device does not expect that the symbols in both consecutive slots in one reference signal cluster for transmitting the first reference signal are uplink symbols. Even if the network side cannot guarantee that the terminal device is not constrained by the protocol, for example, the terminal device does not receive the first reference signal on the uplink symbol.

In some embodiments, the first reception scheme includes: in the at least one reference signal cluster, the terminal device does not receive the first reference signal in case that a time unit for transmitting the first reference signal is an uplink time unit or a flexible time unit.

Specifically, for example, in the at least one reference signal cluster, the terminal device does not receive the first reference signal in the case that the slot used for transmitting the first reference signal is an uplink slot or a flexible slot. Or in the at least one reference signal cluster, the terminal device does not receive the first reference signal in the case that the symbol used for transmitting the first reference signal is an uplink symbol or a flexible symbol.

In some embodiments, in the at least one reference signal cluster, the network device does not send the first reference signal to the terminal device in case the time unit for transmitting the first reference signal is an uplink time unit or a flexible time unit.

Specifically, for example, in the at least one reference signal cluster, the network device does not send the first reference signal to the terminal device in the case that the slot used for transmitting the first reference signal is an uplink slot or a flexible slot. Or in the at least one reference signal cluster, the network device does not send the first reference signal to the terminal device in the case that the symbol used for transmitting the first reference signal is an uplink symbol or a flexible symbol.

In some embodiments, the first reception scheme includes: in the at least one reference signal cluster, the terminal device does not receive the first reference signal in case that a time unit for transmitting the first reference signal is an uplink time unit.

Specifically, if a time slot occupied by the transmission of any one of the first reference signals is an uplink time slot, the network device cancels the transmission of the first reference signal on the time slot. Or if the symbol occupied by the transmission of any one of the first reference signals is an uplink symbol, the network device cancels the transmission of the first reference signal on the symbol. Or any symbol occupied by the transmission of the first reference signal is a flexible symbol, and the network device cancels the transmission of the first reference signal on the symbol. Or if the time slot occupied by any one of the first reference signal transmission is a flexible time slot, the network device cancels the first reference signal transmission in the time slot. These combinations are equally applicable to the following schemes and will not be described in detail.

In some embodiments, the transmission of the first reference signal on the first time unit in the at least one reference signal cluster is in conflict with the uplink transmission. In this case, the terminal device receives the first reference signal at a second time unit subsequent to the first time unit. That is, the network device transmits the first reference signal to the terminal device at a second time unit subsequent to the first time unit. That is, the first reference signal that should have been transmitted on the first time unit is delayed to be transmitted on the second time unit.

In some embodiments, the first time unit may be a symbol or a slot.

In some embodiments, the second time unit is a downlink time unit nearest to the first time unit.

In some embodiments, the second time unit is determined based on a first time domain offset (timeoffset) carried in a MAC CE used to activate the secondary cell. Alternatively, the unit of the first time domain offset may be a slot or a symbol.

In some embodiments, when the unit of the first time unit is a symbol, the second time unit is the time slot nearest to the first time unit, and there is no collision between the transmission of the first reference signal and the uplink transmission in the corresponding pattern of the first reference signal.

In some embodiments, the pattern of at least one of the first reference signals may be agreed upon by way of a protocol agreement.

In some embodiments, transmissions of a first reference signal on a time unit in a first reference signal cluster in the at least one reference signal cluster collide with uplink transmissions. In this case, the terminal device receives the first reference signal on at least two consecutive downlink slots following the first reference signal cluster. Correspondingly, the network device sends the first reference signal to the terminal device on at least two consecutive downlink timeslots after the first reference signal cluster. That is, the first reference signal that should have been transmitted on the first reference signal cluster is delayed to be transmitted on the at least two consecutive downlink slots.

In some embodiments, the at least two consecutive downlink time slots are at least two consecutive downlink time slots closest to the first reference signal cluster.

In some embodiments, the at least two consecutive downlink timeslots are determined based on a second time domain offset carried in a MAC CE used to activate the secondary cell. Alternatively, the unit of the second time domain offset may be a slot or a symbol.

In some embodiments, the at least one reference signal cluster includes a first reference signal cluster and a second reference signal cluster, and the second reference signal cluster is located after the first reference signal cluster, if there is a collision between transmission of the first reference signal on a time unit in the first reference signal cluster and uplink transmission, and the first reference signal corresponding to the time unit in the first reference signal cluster where the collision occurs delays transmission of the first reference signal, the second reference signal cluster also extends backward, and an interval between a time unit in which a last first reference signal transmitted on the first reference signal cluster is located and a time unit in which a first reference signal transmitted on the second reference signal cluster is located is greater than or equal to a first threshold. For example, the first threshold is 2 time slots.

In some embodiments, the first threshold is configured by the network device or the first threshold is agreed upon by the protocol.

In some embodiments, the transmission of the first reference signal on the first symbol in the at least one reference signal cluster is in conflict with the uplink transmission. In this case, the terminal device receives the first reference signal according to the adjusted pattern of the first reference signal on the slot where the first symbol is located, where no symbol that conflicts between transmission of the first reference signal and uplink transmission exists in the adjusted pattern of the first reference signal. Correspondingly, the network device sends the first reference signal to the terminal device according to the adjusted pattern of the first reference signal on the time slot where the first symbol is located.

In some embodiments, the transmission of the first reference signal on the first symbol in the at least one reference signal cluster collides with the uplink transmission, and there is no pattern of the first reference signal in the at least one pattern of the first reference signal that collides with the uplink transmission. In this case, the network device does not send the first reference signal to the terminal device on the first symbol; or, the network device transmits the first reference signal to the terminal device on a first slot after the first symbol.

In some embodiments, the first slot is the slot closest to the first symbol, and there is no collision between the transmission of the first reference signal and the uplink transmission in the corresponding pattern of the first reference signal.

In some embodiments, the transmission of the first reference signal on a time unit in the at least one reference signal cluster is in conflict with the uplink transmission. In this case, the terminal device receives the first reference signal on a target downlink resource, wherein the target downlink resource is obtained by shifting the at least one reference signal cluster backward as a whole. Correspondingly, the network device sends the first reference signal to the terminal device on the target downlink resource. That is, the first reference signal that should have been transmitted on the at least one reference signal cluster is delayed until it is transmitted on the target downlink resource.

In some embodiments, the target downlink resource is the downlink resource closest to the at least one reference signal cluster, and the first reference signal corresponding to the at least one reference signal cluster may be transmitted.

Specifically, for example, the at least one first reference signal burst includes two reference signal clusters, if a collision occurs in a slot or symbol transmitted in the first reference signal, the first reference signals transmitted in the two reference signal clusters are delayed to the next nearest downlink resource location in which the two reference signal clusters can be transmitted as a whole, and an interval between the two reference signal clusters after the offset is unchanged.

In some embodiments, the target downlink resource is determined based on a third time domain offset carried in a MAC CE used to activate the secondary cell. Alternatively, the unit of the third time domain offset may be a slot or a symbol.

Therefore, in the embodiment of the present application, the first information is used to determine the transmission direction information, the second information is used to determine the time domain location information of the first reference signal, the first reference signal is used to activate the carrier, the time domain location information of the first reference signal includes at least one reference signal cluster, and one reference signal cluster corresponds to two consecutive slots. Thus, the terminal device may determine a first reception scheme for receiving the first reference signal based on the first information and the second information. Therefore, the receiving mode of the first reference signal can be optimized, and the transmission of the first reference signal is prevented from colliding with the transmission of other signals. Further, the present application further defines a processing manner after the collision between the transmission of the first reference signal and the uplink transmission, that is, the present application can identify and process the collision between the transmission of the first reference signal and the uplink transmission, so that the terminal device can quickly activate the SCell based on the first reference signal.
